A recipe for brownies calls for 4 cups of flour to 6 cups of sugar. How many cups of sugar, per cup of flour, does the recipe require? Show your work.

Answer:

3 Quarters 9 dimes 14 pennies

Step-by-step explanation:

so dimes are x, quarters are y, and pennies are z. Next we know that x*3 y is what dimes are and 5 more pennies then dimes so z+5. Now we do 3 quarters since thats about 100  but less then 3*3=9 so 190 we have 90+75 cents now then we add 14 the cursed number lol but we add 14 because 9+5 is 14 and there are 5 more pennies then dimes.

Area of parallelogram [tex]A=base\times height[/tex]

Using base as AB and height as DE

[tex]Area=8\times 5[/tex]

Now, using base BC and height as DF

[tex]Area=6.4\times x[/tex]

Equating area

[tex]8\times5=6.4\times x\\x=6.25\ cm[/tex]

The height of the building is 21.38 m

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The image attached shows the measures and angles provided in the problem. The first angle of elevation is y=22°, the man walks B=20 m and finds the new angle of elevation is x=33°.

It's required to find the height of the building H.

The tangent ratio relates the opposite side with the adjacent side of a given angle. Applying it to the larger triangle:

[tex]\displaystyle \tan y=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

[tex]\displaystyle \tan 22^\circ=\frac{H}{D+B}[/tex]

Multiplying by D+B:

[tex]\tan 22^\circ(D+B)=H[/tex]

Dividing by tan 22°

[tex]\displaystyle D+B=\frac{H}{\tan 22^\circ}[/tex]

Subtracting B:

[tex]\displaystyle D=\frac{H}{\tan 22^\circ}-B\qquad\qquad[1][/tex]

Applying to the smaller triangle:

[tex]\displaystyle \tan 33^\circ=\frac{H}{D}[/tex]

Multiplying by D:

[tex]\tan 33^\circ D=H[/tex]

Substituting from [1]:

[tex]\displaystyle \tan 33^\circ \left(\frac{H}{\tan 22^\circ}-B\right)=H[/tex]

Substituting values:

[tex]\displaystyle 0.6494 \left(\frac{H}{0.4040}-20\right)=H[/tex]

Operating:

[tex]1.6074H-12.988=H[/tex]

[tex]1.6074H-H=12.988[/tex]

[tex]0.6074H=12.988[/tex]

[tex]H = 12.988/0.6074[/tex]

H = 21.38 m

The height of the building is 21.38 m

Answer:

Step-by-step explanation:

It would be easier to just show you.

Because we're using variables, I'm going to plug in a random set of numbers to stand for x and y.

(x+y)^2

(2+4)^2=36

vs.

x^2+y^2

2^2+4^2=20

The difference is because, following the order of operations, in the first situation you must first take care of what is in the parenthesis, which means you add x and y together-then you multiply that combined number by the 2nd power. Whereas in the second situation, you multiply x and y by the 2nd power separately, and then add the product of that together. So opposite order. In the first situation you add, then multiply. In the second, you multiply then add.

Answer:

The rule for the linear function will be:

f(x) = -2x+1

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear  as shown in the attached graph

Taking two points

Finding the slope between (0, 1) and (1, -1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [-1 - 1] / [1 - 0]

                = -2 / 1  

                = -2

Thus, the slope of the line = m = -2

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 1

Thus, the y-intercept b = 1

Now, substituting m = -2 and b = 1 in the slope-intercept form of linear function

y = mx+b

y = (-2)x + 1         ∵ m = -2, b = 1

y = -2x+1

f(x) = -2x+1

Therefore, the rule for the linear function will be:

f(x) = -2x+1

Answer:

4(2+t)

Step-by-step explanation:

A term is a single mathematical expression.  We can see in this expression there are four terms, each separated by an operation:

8, 6t, -3t, and 1.

Coefficients are the numbers that multiply variables.  You can also just think of them as the number in front of any variable.  Here we see we have two terms with variables:

6t, -3t

and therefore our coefficients are:

6, -3

Constants are numbers that are, well, constant - you could also just think of them as "normal" numbers.  We can see in this expression you have two:

8, 1

Like terms are terms of the same type.  We have two like terms with a variable in them:

6t, -3t

and two like terms that are constants:

8, 1

Step-by-step explanation:

Answer:

80%

Step-by-step explanation:

We can write the ratio of first graders to students as 56:24.

We have to find the total amount of students so we add those two up and we get 70

Out of 70, there are 56 first graders, so we can write that as a fraction which will be 56/70

To get this to a percent, we have to get it so the denominator is 100, I can do some weird thing, multiplying a decimal over decimal to get to the answer, but that isn't what you would most likely do

The best thing to do in this scenario is to simplify this equation so it has a denominator of 10, so we do divide by 7 on the bottom, divide by 7 on the top, and we get the more simplified fraction, 8/10. And 8/10 is also equal to 80/100 which makes the percent 80%

Answer:

8.6

Step-by-step explanation:

From the above question, we know that the length of the third side is the longest. Hence, we apply Pythagoras Theorem

c² = a² + b²

a = 5, b = 7

c = Third side

c = √a² + b²

c = √5² + 7²

c = √25 + 49

c = √74

c = 8.602325267

Approximately c = 8.6

Possible length of the third side = 8.6

Answer: -9

Step-by-step explanation: Your welcome

Answer:

first option

Step-by-step explanation:

Given

f(x) = [tex]\frac{2x^2+5x-12}{x+4}[/tex] ← factorise the numerator

     = [tex]\frac{(x + 4)(2x-3)}{x+4}[/tex] ← cancel (x + 4) on numerator/ denominator

     = 2x - 3

Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is

x = - 4

Substitute x = - 4 into the simplified f(x) for y- coordinate

f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11

The discontinuity occurs at (- 4, - 11 )

To obtain the zero let f(x) = 0, that is

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

There is a zero at ( [tex]\frac{3}{2}[/tex], 0 )

Thus

discontinuity at (- 4, - 11 ), zero at ( [tex]\frac{3}{2}[/tex], 0 )

Answer:

Step-by-step explanation:

[tex] = > 5(x + 6) - 15(2 - x) = 10(3x - 1)[/tex]

[tex]5x + 30 - 30 + 15x = 30x - 10[/tex]

[tex] = > 20x = 30x - 10 \\ = > 20x - 30x = - 10 \\ = > - 10x = - 10 \\ = > x = 1[/tex]

Answer: 7) No   8) No

Step-by-step explanation:

According to the Pythagoras theorem of the right triangle,

Square of largest side = Sum of square of other two sides.

8) Given sides: 5cm, 12cm, 14cm

Here, Largest sides = 14 cm

[tex]5^2+12^2=25+144=169\neq14^2 \ \ \ [14^2=196][/tex]

These sides do not represent a right triangle.

7) Given sides:  9m, 4m, 5m

Largest side = 9 m

[tex]4^2+5^2=16+25=49\neq 9^2 \ \ \ \ \ [9^2=81][/tex]

These sides do not represent a right triangle.

Answer:

V = hπr^2

V = 5 X π X 15^2

V = 3534.29173

V = 3534.2 cubic feet

The equation that can be used to find the volume V of the swimming pool is πr²h

The swimming pool is circular and has a diameter of 30 feet and a depth of 5 feet.

This simply means the swimming pool follows the shape of a cylinder. The

two bases are circular and has a height of 5 feet.

Therefore, the volume of the swimming pool in cubic feet is the volume of a cylinder.

volume = πr²h

where

r = radius = 30 / 2 = 15 feet

h = 5 feet

volume = 3.14159 × 15² × 5 = 3.14159 × 225 × 5 = 3534.28875 = 3534.3 ft³
