Find the value of x. Then find the measure of each labeled angle.

Nat2105 [25]

Answer:

x = 70; the labeled angles are 110º and 70º.

Step-by-step explanation:

The full degrees will add up to 180º. There are 2x and +40.

Equation: $2x+40=180$

Solve: $2x+40=180\\\\180-40=140\\\\2x=140\\\\x=70$

Since x=70, 70+40 will equal to 110.

Therefore, "x = 70; the labeled angles are 110º and 70º." is correct.

A family goes on a long car trip. The number of miles, y, they have left to drive is given by the equation y=510−60x, where x re

Korvikt [17]

Answer:

0,1.5

Step-by-step explanation:

y = 510 - 60x

We want to find the domain or the x values where x represents the time

We need to determine the possible values for x

Y cannot be greater than 510 or less than 0. 510 means they have not started the trip, and 0 means they have arrived

510 = 510 -60x

Subtract 510 from each side

510-510 = 60x

0 = 60x

The smallest value of x can be 0

0 = 510 - 60x

Subtract 510 from each side

-510 = 510-510-60x

-510=-60x

Divide by -60

-510/-60 = -60x/-60

8.5 = x

The maximum value of x is 8.5 hours

So x must be between 0 and 8.5 inclusive.

A right cylinder has a radius of 6 m and a surface area of 84 m². Find the surface area of a similar cylinder with a radius of 2

dlinn [17]

Answer:

The surface area of the second cylinder is equal to $9.33\ m^{2}$

Step-by-step explanation:

we know that

If two figures are similar then

the ratio of their surfaces areas is equal to the scale factor squared

Let

z-------> the scale factor

x------> the surface area of the smaller cylinder (second cylinder)

y-------> the surface area of the original cylinder (first cylinder)

$z^{2}=\frac{x}{y}$

Step 1

Find the scale factor

$z=\frac{2}{6}=\frac{1}{3}$

Step 2

Find the surface area of the second cylinder

we have

$z=\frac{1}{3}$

$y=84\ m^{2}$

substitute and solve for x

$(\frac{1}{3})^{2}=\frac{x}{84}$

$x=\frac{1}{9}*84=9.33\ m^{2}$
