Option B

The volume of sand he will need to fill half of the sandbox is 55.35 cubic feet

<em><u>Solution:</u></em>

<em><u>The volume of rectangular prism is given as:</u></em>

Volume = base\ area \times height

From given,

Area of base = 49.2 square feet

Height = 2.25 feet

<em><u>Substituting the values we get,</u></em>

Volume = 49.2 \times 2.25\\\\volume = 110.7

Thus volume of sand box is 110.7 cubic feet

Mr. Berger plans to fill the sandbox half full of sand

So find half the volume

volume of sand he will need to fill half of the sandbox is given as:

\rightarrow \frac{110.7}{2} = 55.35

Thus the volume of sand he will need to fill half of the sandbox is 55.35 cubic feet

If line t is a transversal of lines l and m, name the angle relationship of the given angle pairs.
Ghella [55]

Answer:

\angle 1\ and\ \angle 3 are corresponding angles and are congruent to each other.

\angle 8\ and\ \angle 4 are alternate exterior angles and thus congruent to each other.

\angle 2\ and\ \angle 3 are interior angles on the same side, and they are supplementary(sum=180°).

Step-by-step explanation:

Given:

Line l\parallel m

Line t is traversal.

By angle properties we can name the angle relationship of given angle pairs.

\angle 1\ and\ \angle 3 are corresponding angles and are congruent to each other.

\angle 8\ and\ \angle 4 are alternate exterior angles and thus congruent to each other.

\angle 2\ and\ \angle 3 are interior angles on the same side, and thus they are supplementary.

A family purchased basketball tickets online. The total cost, c, in dollars, of t tickets can be found using the function below.
Reptile [31]
Solution:
C=32.50t+8.50
236=32.50t+8.50
236-8.50=32.50t
227.50=32.50t
227.50/32.50=32.50t/32.50
t=7

The family bought 7 tickets.

Hi! ❤️ , im looking for some help here. ill give brainliest if able to.
Alexeev081 [22]

Answer:

A. 2^11

Step-by-step explanation:

(They are basically asking what's 2^4 × 2^7, but with more words.)

I usually do each exponent individually:

2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)

2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128

Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.

BUT, you can also:

(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)

2^4 × 2^7

4 + 7 = 11

2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).

Hope this helps friend :)

The last part I learned from another user, while answering one of your other questions. I personally find this mind blowing, lol.
