Answer:

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

-7 -7

2x = 8

divide by 2 to isolate x

x = 4

2nd pic) y - 3 <= 6

y - 3 <= 6

+3 +3

y <= 9

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

-0.5 -0.5

x = x + 5.5

NO SOLUTION

4th pic) 5m + 10 <= 130

5m + 10 <= 130

-10 -10

5m <= 120

divide by 5 to isolate the m

m <= 24

5th pic) 2c - 8 > 0

2c - 8 > 0

+8 +8

2c > 8

divide by 2 to isolate the c

c > 4

For lines a , c , and d , line c is parallel to line d and m ∠ 1 = 55 ° . Part A: For the given diagram, use the measure of ∠ 1

pentagon [3]

Answer:

Part A:

1, 4, 5, and 8 = 55 degrees.

3, 2, 6, and 7 = 125 degrees.

Part B:

I know that angle 1 is 55 degrees so angle 7 would be 125.

I know that angle 1 is 55 and to get angle 2, both angles should add up to 180 so 180 - 55 is 125, that is how I find angle 2 = 125 degrees.

Step-by-step explanation:

This is what I wrote, I hope it helps and tell me if I am wrong but I think it is right.

Use differentials to estimate the amount of paint needed to apply a coat of paint 0.07 cm thick to a hemispherical dome with dia

Mademuasel [1]

An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.

We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.

This differential volume that the dome is increased is equal to the volume of the coat of paint.

The volume of the dome can be written as:

$\begin{gathered} V=\frac{4\pi}{3}r^3 \\ \frac{dV}{dr}=\frac{4\pi}{3}\cdot3r^2\Rightarrow dV=\frac{4\pi}{3}\cdot3r^2\cdot dr=4\pi r^2\cdot dr \end{gathered}$

Now, we can calculate dV as:

$\begin{gathered} dV=4\pi r^2\cdot dr \\ dV\approx4\cdot3.14\cdot(30m)^2\cdot0.07\operatorname{cm}\cdot\frac{1m}{100\operatorname{cm}} \\ dV\approx12.57\cdot900m^2\cdot0.0007m \\ dV\approx7.92m^3 \end{gathered}$

Answer: the paint needed for this coat is approximately 7.92 m^3
