Answer:

85%

Step-by-step explanation:

To find the percentage we will have to start by dividing the amount he brings home by the gross.

156.4 / 184 = 0.85

By doing this, we get the answer in decimal form, which is not what we want.

Multiply it by 100 to convert it into a percent.

0.85 x 100 = 85.

Now, we know that he brings home 85% of his gross.

Use the substitution methods to solve the system of equations. Choose the correct ordered pair. y=7x+8 y=x+20

krek1111 [17]

Answer:

Step-by-step explanation:

Solution by substitution method

y=7x+8

∴y-7x=8

and y=x+20

∴y-x=20

Suppose,

-7x+y=8→(1)

and -x+y=20→(2)

Taking equation (1), we have

-7x+y=8

⇒y=7x+8→(3)

Putting y=7x+8 in equation (2), we get

-x + 7x + 8 = 20

6x = 20-8

6x = 12

x= 12 / 6

x = 2

substitute for x in equation (3)

y = 7(x) + 8

y = 7(2) + 8

y = 22

Answer:

The volume of the solid is $1,021m^3$

Step-by-step explanation:

1. Cylinder

For find the volume of a cylinder we use the next formula:

$V_{cylinder} = \pi h r^2 = \pi \cdot 9m\cdot (5m)^2 \approx 706.86m^3$

Then the volume of the cylinder is equal to $706.86m^3$

2. Cones

For find the volume of a cone we use the next formula:

$V_{cone} = \pi \frac{h}{3} r^2 = \pi \cdot \frac{6m}{3} \cdot (5m)^2 \approx 157.08m^3$

However there are two cones so we have to multiply the volume of one cone for two and we get the total volume for the cones which is $314.16m^3$

3. Sum of the volumes

Finally we sum the volumes of the cylinder and the cones for get the final result

$V_{cylinder} + V_{cones} = 706.86m^3 + 314.16m^3 \approx 1021m^3$

So approximating the result is $1021m^3$

Answer:

222

Step-by-step explanation:

Closely pay attention to the transversal line running from up-left to down-right.

y) you will notice that the angle to the right of z is corresponding with 50 then 50 will be vertically opposite 6y + 2 hence making them equal.

6y - 2 = 50

6y = 50 - 2

6y = 48

y = 6

z) vertically opposite angles are equal hence the 50 will be equal to the empty space in the triangle.

z + 60 + 50 = 180

z + 110 = 180

z = 180 - 110

z = 70

2y + 3z

2(6) + 3(70)

12 + 210

= 222

3 3Cylinder A 3 3 4 4Cylinder B 2 2 What is the ratio of the volume of Cylinder A to the volume of Cylinder B? Choose 1 answer:

frutty [35]

Answer:

(D) $\dfrac{27}{16}$

Step-by-step explanation:

Volume of a Cylinder = $\pi r^2h$

Cylinder A

Height = 3 Units

Radius = 3 Units

$Volume =\pi \times 3^2 \times 3 =27\pi$ cubic units$

Cylinder B

Height = 4 Units

Radius = 2 Units

$Volume =\pi \times 2^2 \times 4 =16\pi$ cubic units$

$\dfrac{\text{Volume of Cylinder A}}{\text{Volume of cylinder B}}=\dfrac{27\pi}{16\pi}\\\\=\dfrac{27}{16}$

The correct option is D
