Step-by-step explanation:

Step 1: <em>Calculate per apartment;</em>

<em>⟼</em> 228,000 ÷ 24

⟼ 9,500

Step 2: <em>Multiply the price per apartment by 10;</em>

⟼ 9,500 × 10

⟼ 95,000

Step 3: <em>Substract the amount of 10 apartments from 24 apartments.</em>

<em>⟼</em><em> </em>228,000 - 95,000

⟼ 133,000

<u>Therefore, </u>$133,000 is still available for the remaining apartments.

Integrate with respect to x <br><br> 1/√(1-2x)
Ilia_Sergeevich [38]

Answer:

-√(1 - 2x) + C

Step-by-step explanation:

1/√(1-2x)

We want to integrate it. Thus;

∫1/√(1 - 2x) dx

Let u = 1 - 2x

Thus;

du/dx = -2

Thus, dx = -½du

Thus,we now have;

-½∫1/√(u) du

By application of power rule, we will now have;

-½∫1/√(u) du = -√(u) + C

Plugging in the value of u, we will have;

-√(1 - 2x) + C

A shipping carton is in the shape of a triangular prism. How many cubic inches
olga55 [171]

Answer: 90 inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a rectangular prism =area of the base x length  

Area of the base is the area of a triangle:

Area of a triangle = base x height x 1/2

Replacing with the values given:

A = 4 x 3 x 1/2 = 6 in2

Back on the volume formula:

V = A x h = 6 x 15 = 90 cubic inches  

Feel free to ask for more if needed or if you did not understand something.

Andre is preparing for the school play and needs to paint the cardboard castle backdrop that measures  feet by 6 feet.
7nadin3 [17]

Answer:

a. 85.5 sq ft

b. 3 bottles

Step-by-step explanation:

a. The cardboard is rectangular in shape. How much he needs to paint is the same as the cardboard that he needs to paint.

The area of a rectangle is given as:

A = L * B

where L = length and B = breadth

Therefore, the area of the cardboard having dimensions 14 1/4 feet by 6 feet is:

A = 14 1/4 * 6

A = 57 / 4 * 6 = 85.5 sq feet

He needs to paint 85.5 sq feet of the cardboard.

b. On bottle of paint covers 40 sq feet. The number of bottles he will need for his backdrop will be the area he needs to paint divided by the amount of paint that can cover 40 sq feet:

85.5 / 40 =  2.14

Since the number of bottles he will need is a whole number and its greater than 2, then it must be 3.

To paint the entire cardboard, he must have 3 bottles of paint.

A public opinion survey investigated whether a majority (more than 50%) of adults supported a tax increase to help fund the loca
soldier1979 [14.2K]

Answer: C. At the α=0.05 significance level, they should conclude that more than 50% of adults support the tax increase.

Step-by-step explanation:

Given: Null hypothesis: H_0:p=0.5

Alternative hypothesis: H_a: p>0.5

p-value = 0.033

If the p-value is greater than alpha (p > . 05), then we fail to reject the null hypothesis.

If α=0.01 , then p-value > α i.e. we fail to reject the null hypothesis.

Conclusion: Exactly 50% of adults support the tax increase.

If α=0.05 then p-value < α i.e. we reject the null hypothesis.

Conclusion: more than 50% of adults support the tax increase.

Thus, Correct option: C .
