Answers

Answer:

The list of angles of the triangle in order from smallest to largest will be: A < C < B

Hence, option 'e' is true.

i.e (A,C,B)

Step-by-step explanation:

We know that in a triangle the greater angle has the longer side opposite to it.

From the given triangle,

Side AC = 7.2 is the longer side. Thus, B is the largest angle as it is opposite to the longer side AC = 7.2.

Then comes the second-longest side AB=4.9. Thus, C is the 2nd largest angle it is opposite to the second-longest side AB=4.9.

Finally comes the shortest side BC = 3.2. Thus, A is the shortest angle as it is opposite to the shortest side BC = 3.2.

Thus, the list of angles of the triangle in order from smallest to largest will be: A < C < B

Hence, option 'e' is true.

Ryan bys plates and cups for a party. There are 12 plates in a pack and 10 cups in a
pack. He wants an equal number of plates and cups for a the party. What is the least number
of packs of plates and the least number of packs of cups that Ryan must buy?

Help please

Answers

Answer:

• 5 packs of plates

• 6 packs of cups

Step-by-step explanation:

5 packs of plates = 60 plates (5×12)

6 packs of cups = 60 cups (6×10)

Answer:

5 packs of plates

6 packs of cups

========================================================

Explanation:

GCF = greatest common factor

LCM = lowest common multiple

The GCF of 12 and 10 is 2 since

12 = 2*610 = 2*5

It's the largest factor they have in common together.

Multiply 12 and 10, then divide by the GCF to get the LCM

LCM = (12*10)/GCF = 120/2 = 60

The LCM is 60. We can verify this by looking at a few multiples like so

multiples of 12 are: 12, 24, 36, 48, 60, 72, ...multiples of 10 are: 10, 20, 30, 40, 50, 60, 70, ...

The LCM is the amount of plates and cups that match up.

Buying 5 packs of 12 plates gets 5*12 = 60 plates total

Buying 6 packs of 10 cups each gets 6*10 = 60 cups total

You need to paint a decorative garden ornament that is in the shape of pyramid with a square base

that is 9 inches long and has a slant height of 12 inches.

a. A smaller pyramid has linear dimensions that are

times that of the larger pyramid. Does the

smaller pyramid require times the amount of paint? Explain.

b. Another pyramid has the same base lengths but the slant height. Does this pyramid require

the paint as the original pyramid? Explain.

Answers

Step-by-step explanation:

Total Surface area of a pyramid is given as

= Lateral surface area + area of base.

Lateral surface area = 1/2×perimeter of base×slant height

given the base is square with side 9 in , and slant height of 12 inches.

therefore, LSA = 1/2(9*4)×12 = 216 in^2

Now, TSA = LSA + Base area = 216+9^2 = 297 in^2

a) It is given that the pyramid is smaller therefore, it will require lesser paint than the original pyramid ( The TSA of the smaller pyramid cannot be calculated as its dimentions are not given).

b) It can not be solved as dimensions are missing in the question.

However, the logic has been explained in the soluion one easily put values to find the solution.

Gladys scored 42 points in a basketball game. She only took 2-point shots and 3-point shots. She made a total of 18 shots. Write a system of equations to find the number of 2-point shots and 3-point shots Gladys made. Let LaTeX: xx represent the number of 2-point shots and LaTeX: yy represent the number of 3-point shots that Gladys made.

Answers

Answer:

[tex]x+y=18 \\2x+3y=42[/tex]

Number of 2-point shots taken = 12

Number of 3-point shots taken = 6

Step-by-step explanation:

Total number of points scored by Gladys = 42

Only 2-point and 3-point shots are taken by Gladys.

Let number of 2-point shots taken = [tex]x[/tex]

Let number of 3-point shots taken = [tex]y[/tex]

Total number of shots taken = 18

Therefore, first equation can be written as:

[tex]x+y=18[/tex]

Total points scored = 42

Therefore, second equation can be written as:

[tex]2x+3y=42[/tex]

System of equations is:

[tex]x+y=18 .... (1)\\2x+3y=42 .... (2)[/tex]

Using elimination method to solve the system of equations.

Multiplying equation by 2 then subtracting it from equation (2):

[tex]3y - 2y = 42 - 36\\\Rightarrow y = 6[/tex]

By equation (1):

[tex]x+6=18\\\Rightarrow x = 12[/tex]

Therefore, Number of 2-point shots taken = 12

Number of 3-point shots taken = 6

HELPP I NEED TO SUMBIT SOON

Answers

The distributive property states: a(b+c)=a•b+a•c. In other words, the terms inside the parentheses are multiplied by the factor outside the parentheses; remember that a(b)=a•b

1.) 4x+12

2.) -28+7y

3.) 18x+30y-24

4.) For number 4, is the question 9(a-3/3) or a different expression? If it’s the first one, then it equals 9a-9.

5.) To factor out the GCF, we need to find the greatest factor that divides into both 64 and 24. We will find that 8 is the largest factor of 24 and 64. Therefore, all terms are divided by 8, and 8 remains out in front. We are essentially “undoing” distribution. We need to factor out a number that will make the multiples of 64 and 24.

(64+24)/8

5.) Answer: 8(8x+3)

Notice that if we distribute, we end up with 64x+24, so we simply revers distribution. Since distribution is multiplication, and division reverse multiplication into a simplified form, we divided each term by the GCF of 8.

6.) Factor out a GCF that divides into -5y and -35. The GCF is 5, since 5 divides evenly into both terms.

(-5y-35)/5

5(-y-7) is the answer.

Also notice that even though both terms were divided by 5, we kept the 5 out in front to distribute. This is because the goal of factoring is to break the expression down into a simplified, equivalent form.

37: given the line y=3/4x-2

39: write an equation of a line that passes through (-4,-6) and is parallel to y=3x-8

40: write an equation of a line that passes through (2,5) and is perpendicular to y=1/4x-12

Answers

Step-by-step explanation:

Two lines are parallel if they have the same slope and are perpendicular if the product of their slopes is -1

37.a.Parallel slope=¾

b.Perpendicular slope =-1/¾=-4/3

38.a. -2x+5y=9 and 5x+2y=-6

For the first line,5y=2x+9,y=2/5x+9/5

For the second line,2y=-6-5x,y=-3-5/2x

Compare the slopes

2/5 vs -5/2 we see that -5/2 is the negative reciprocal of 2/5 therefore they are perpendicular

39. If both lines are parallel then their slopes are equal. The slope of y=3x-8 is 3

Using the point-slope form, y-y1=m(x-x1)

y--6=3(x--4)

y+6=3(x+4)

y+6=3x+12

y=3x+12-6

y=3x+6

40.The slope of y=¼x-12 is ¼

The negative reciprocal of it is the slope of it's perpendicular that is -1/¼=-4

Using the point slope form, y-y1=m(x-x1)

y-5=-4(x-2)

y-5=-4x+8

y=-4x+8+5

y=-4x+13

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

Given that

⇒ f(x) = -x² – 10x

To determine the value of f(-5)

Substitute the value x = -5

⇒f(-5 ) = -(-5)² - 10(-5)

⇒f(-5 ) = 25

Hence, the value of f(-5) is 25 when x = -5

The function f(t) = 750t + 20,000 models the number of movie theaters in the United States t years after 1985. Use this equation to predict the year in which the United States will have 35,000 movie theaters.

Answers

Given:

The function models the number of movie theaters in the United States t years after 1985.

[tex]f(t)=750t+20,000[/tex]

To find:

The year in which the United States will have 35,000 movie theaters.

Solution:

We have,

[tex]f(t)=750t+20,000[/tex]

Putting f(t)=35000, we get

[tex]35,000=750t+20,000[/tex]

[tex]35,000-20,000=750t[/tex]

[tex]15,000=750t[/tex]

Divide both sides by 750.

[tex]\dfrac{15,000}{750}=t[/tex]

[tex]20=t[/tex]

It means, United States will have 35,000 movie theaters 20 years after 1985.

[tex]1985+20=2005[/tex]

Therefore, United States will have 35,000 movie theaters is 2005.

The function h(x) passes through the point (-8,9). What point must lie on h^-1(x)?

Answers

Answer:

Step-by-step explanation:

h^-1(x) is the inverse of h(x) so its graph is the reflection of h(x)

in the lines y =- x.

This reflection is (x, y) ---> (y , x)

So the required point is (9, -8)

The point (9, -8) must lie on the inverse function [tex]h^{(-1)}(x)[/tex].

To find the point that must lie on the inverse function [tex]h^{(-1)}(x)[/tex], use the fact that points on the original function and its inverse are reflections over the line y = x.

If the point (-8, 9) lies on the function h(x), then the inverse function [tex]h^{(-1)[/tex](x) will have a point that is the reflection of (-8, 9) over the line y = x.

The coordinates of the reflected point will simply swap the x and y values. So, the point that must lie on [tex]h^{(-1)[/tex](x) is (9, -8).

Therefore, the point (9, -8) lie on the function [tex]h^{(-1)}(x)[/tex].

mrs. page needed two types of paper for her art class. the premium color paper costs $40 per case and the plain white paper costs $30 per case. if she bought 20 cases all together and spent $720 total, how many cases of plain white paper did she buy?

Answers

Mrs. Page bought 8 cases of plain white paper.

To solve for the number of cases of plain white paper Mrs. Page bought, we will use algebraic expressions.

Algebraic expression is an expression consisting variables ad coefficient.

We will designate a variable for the unknown and solve it using the algebraic expressions made.

The number of cases of plain white paper and premium color paper is unknown.

Let x = number of cases of plain white paper

and y = number of cases of premium color paper

If Mrs. Page bought 20 cases altogether, then

x + y = 20

If Mrs. Page spent a total of $720 for the 20 cases, and the premium color paper costs $40 per case and the plain white paper costs $30 per case, then:

30x + 40y = 720

Multiplying the first equation by 30, we get:

30x + 30y = 600

Subtracting it to the 2nd equation,

30x + 40y = 720

- 30x + 30y = 600

10y = 120

y = 12

Recall that x + y = 20. Then,

x + 12 = 20

x = 8

Hence, Mrs. Page bought 8 cases of plain white paper and 12 cases of premium color paper.

The surface area of a solid is 4500 square inches. Is the surface area greater than 3 square yards

Answers

If the surface area of the solid is 4500 square inches, then the surface area of the solid is greater than 3 square yards

What are areas?

The area of a shape is the amount of space on the shape.

For most regular quadrilaterals, the area is the product of the length and the width of the quadrilateral

Is the surface area greater than 3 square yards?

The surface area of the solid is given as

Surface area = 4500 square inches

As a general rule of unit conversion

1 square inches = 1/1296 square yards

Next, we multiply both sides of the equation by 4500

So, we have

4500 * 1 square inches = 4500 * 1/1296 square yards

Evaluate the products in the above equation

4500 square inches = 3.5 square yards

3.5 square yards is greater than 3 square yards

Hence, the surface area of the solid is greater than 3 square yards
