Answer:

x = 4

Step-by-step explanation:

Since the rectangles are similar, use a ratio.

15/6 = 10/x

or

6/15 = x/10

I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.

15/6 = 10/x

Cross Multiply:

6(10) = 15x

Solve:

60 = 15x

x = 4

Step-by-step explanation:

Answer:

87

Step-by-step explanation:

Hi!

First you add all of the numbers up together:

77+81+93+97= 348

Next, you divide the answer you got above by how many numbers are in your data set:

348/4 = 87

4 because 77,81,93,97 thats four numbers :)

Therefore, Marla's test average is 87!

So anytime you need find the average of any data set, you just add all the numbers together, then divide by the quantity of numbers there are.

The correct answers are E and C.

The question is incomplete, the complete question is;

The radius of the sphere is 10 units.What is the approximate volume of the sphere? Use π = 3.14 and round to the nearest whole cubic unit. cubic units

Answer:

4187 cubic units

Step-by-step explanation:

According to the question;

radius (r) = 10 units

 π = 3.14

Volume of a sphere = 4/3*π*r^3

Substituting values;

V = 4/3*(3.14)*(10)^3

V = 4186.67 cubic units

V = 4187 cubic units (To the nearest whole cubic unit)

Answer:

It's C on Edge

Step-by-step explanation:

Answer:

2(x + 3) = 2x + 6

Step-by-step explanation:

Here, we want to expand

2(x + 3)

To do this, we simply multiply the term outside the bracket with each of the terms inside it

That will be;

(2 * x ) + (2 * 3)

= 2x + 6

Answer:

x = 12

A = 30

Step-by-step explanation:

Here, we want to solve for the value of x

The angle at the top of the triangle is 8x + 4

The reason for this is because vertically opposite angles are equal

Mathematically;

8x + 4 + 3x - 6 = 130

The reason for this is that opposite interior angles equal the exterior angle

Thus;

8x + 3x + 4- 6 = 130

11x -2 = 130

11x = 130 + 2

11x = 132

x = 132/11

x = 12

The value of A is 3x - 6

A = 3(12)-6

A = 36-6

A = 30

Answer: $1.25

Step-by-step explanation:

Given

Graham spends a total of $15.05 on 10 apples and a packet of strawberries

Cost of strawberries packet $2.55

Suppose the cost of each apple is x

So, [tex]10x+2.55=15.05[/tex]

On solving

[tex]\Rightarrow10x=15.05-2.55\\\Rightarrow10x=12.5\\\Rightarrowx=\frac{12.5}{10}=\$1.25[/tex]

The cost of each apple is $1.25

Answer:

Step-by-step explanation:

Answer:

The point-slope equation of the line is y - 2 = 3(x + 9)

Step-by-step explanation:

The form of the point-slope equation is y - y1 = m(x - x1), where

∵ The slope of a line is 3

∴ m = 3

∵ The line passes through point (-9, 2)

∵ x1 = -9

∴ y1 = 2

→ Substitute the values of m, x1, and y1 in the point-slope form

∵ y - y1 = m(x - x1)

∴ y - 2 = 3(x - (-9))

→ Remember (-)(-) = (+)

∴ y - 2 = 3(x + 9)

∴ The point-slope equation of the line is y - 2 = 3(x + 9)

Answer:

Mr. Selan would pay $2.15 for the sandwiches with tax.

Step-by-step explanation:

Given that:

Cost of each sandwich = 99 cents

Cost of two sandwiches = 99*2 = 198 cents

Sales tax = 8.5%

Sales tax = [tex]\frac{8.5}{100}*198=16.8\ cents[/tex]

Sales tax = 17 cents

Total cost = 198 + 17 = 215 cents

Total cost = $2.15

Hence,

Mr. Selan would pay $2.15 for the sandwiches with tax.

Answer:

The required graph is shown below.

Step-by-step explanation:

Consider the given system of linear equations.

[tex]y=x+4[/tex]

Put x=0 in the above equation.

[tex]y=0+4[/tex]

[tex]y=4[/tex]

Now, put y=0 in [tex]y=x+4[/tex].

[tex]0=x+4[/tex]

[tex]x=-4[/tex]

The coordinates are (0,4) and (-4,0). Draw the line by using the points.

Similarly,

Consider the equation [tex]y = 3x - 1[/tex]

Put x=0 in the above equation.

[tex]y=3(0)-1[/tex]

[tex]y=-1[/tex]

Now, put y=0 in [tex]y = 3x - 1[/tex].

[tex]0=3x-1[/tex]

[tex]x=\frac{1}{3}[/tex]

The coordinates are (0,-1) and ([tex]\frac{1}{3}[/tex],0). Draw the line by using the points.

The required graph is shown below.

Answer:

Por tanto, la cantidad de ingredientes necesarios para 6 personas es:

450 g de queso, 15 ml de leche, 150 g de azúcar, 150 g de mantequilla y 75 g de harina.

Step-by-step explanation:

Por lo tanto:

Para queso

4 personas = 300g de queso

6 personas = x

Cruz multiplicar

4x = 6 × 300g

x = 6 × 300 g / 4

x = 450 g de queso

Por 10ml de leche

4 personas = 10 ml de leche

6 personas = x

Cruz multiplicar

4x = 6 × 10 ml

x = 6 × 10 ml / 4

x = 15 ml

Por 100 g de azúcar

4 personas = 100 g de azúcar

6 personas = x

4x = 6 × 100g

x = 6 × 100 g / 4

x = 150 g de azúcar.

Por 100 g de mantequilla

4 personas = 100 g de mantequilla

6 personas = x

4x = 6 × 100g

x = 6 × 100 g / 4

x = 150 g de mantequilla

Por 50 g de harina

4 personas = 50 g de queso

6 personas = x

4x = 6 × 50g

x = 6 × 50 g / 4

x = 75 g de queso.

Por tanto, la cantidad de ingredientes necesarios para 6 personas es:

450 g de queso, 15 ml de leche, 150 g de azúcar, 150 g de mantequilla y 75 g de harina.

Answer: ↓↓↓

Step-by-step explanation:

1. a = ?   b = 16  c = 18

a² + b² = c²

a² + (16)² = (18)²

a² +  256 = 324

     - 256   -256

a² = 68

√a² = √68

a ≈ 8.25

2. a = 4     b = 8     c = ?

a² + b² = c²

(4)² + (8)² = c²

16 + 64 = c²

80 = c²

√c² = √80

c ≈ 8.94

Answer:

5x + 3

Step-by-step explanation:

Since we can see DC is the median of Triangle ABC

So it breaks the into two equal parts

Given

AD = 2x + 5

BD = 3x - 2

Now

AB = AB + BD

= 2x + 5 + 3x - 2

= 5x + 3

Answer:

250 jars

6 hours

Step-by-step explanation:

We know they make 50 jars in an hour, so 50 times 5 is 250 jars in 5 hours. Since 300 is 50 more than 250, and we know 50 times 6 is 300, we can say that we would need 6 hours to make 300 jars.
