Brody wants to build a model ship. He has already saved $30 for the materials and plans. The materials cost $24.89 and the plans

cost $8.29. Brody says he has to save $5.11 more to pay for the materials and plans. Which explanation explains whether Brody is correct or not?
A .Brody is not correct. Estimation: 24.89 – 8.29 is about 17. $30 – $17 = $13. Brody needs to save about $13 more.

B. Brody is not correct. Estimation: 24.89 + 8.29 is about 33. $33 – $30 = $3. Brody needs to save about $3 more.

C. Brody is correct. Estimation: 30.00 – 8.29 is about 22. $22 + $25 = $47. Brody needs to save about $47 more. Assessment navigation

B

Step-by-step explanation:

24.89 can be rounded up to 25, while 8.29 can be rounded down to 8. Adding these together gives 33, meaning that Brody needs to save about another $3. Hope this helps!

The diameter of a cylindrical construction pipe is 6 ft. If the pipe is 26 ft long, what is its volume?
Mandarinka [93]

Answer:

Step-by-step explanation:

First find the area of the circular base. The diameter is 6, so the radius is 3.

A circle is pi r square, so it is 3.14 x 3^2, = 28.26

Multiply that by the length 28.26 x 26 = 734.76, which rounds to 735 cubic feet.

Solve each prportion. (2/y-4)=(y+3/4)
vampirchik [111]

Answer:

y = 5, -4

Step-by-step explanation:

To solve proportions you cross-multiply.

\frac{2}{y-4} =\frac{y+3}{4} \rightarrow 2\times4 = (y-4)\times(y+3) \rightarrow 8=y^2-y-12

Now that we have 8 = y^2 - y - 12, we must make the entire trinomial equal to 0 by subtracting 8 from both sides.

y^2 - y - 20 = 0

Factor the trinomial.

(y - 5)(y + 4) = 0

Make both factors equal to 0 to solve for both values of y.

  • y - 5 = 0 --> y = 5
  • y + 4 = 0 --> y = -4

y = 5, -4
