1 answer:
Marta_Voda [28]3 years ago
7 0

Answer:

13. ft per minute is 150. ft per hour is 9,000.

work:

  • 300÷ 2 = 150
  • 150 times 60 min.

14. x ÷ y = feet per minute.

it is this because the time divided by the depth will equal the time that it took.

15. it would be more reasonable to use feet by minute, because of the accuracy of the answers. with measuring it using feet per hour, your answers will be less precise.

16. the distance will double because the proportional relationship says that the distance is 3 km away if thunder is 9 secs apart from lightning.

will answer next question later

7th grade math problem! Please help!
ANTONII [103]

Volume of the hexagonal prism = 1732.7772 ft³

Solution:

Height of the prism (H) = 15.4 ft

Side of the hexagon base (b) = 6.58 ft

Height from center to the side length (h) = 5.7 ft.

Let us first find the area of the base.

Area of the base (B) =  6\times\frac{1}{2}\  bh

                                 $=6\times\frac{1}{2}\times 6.58 \times 5.7

Area of the base (B) = 112.518 ft²

To find the volume of the hexagonal prism:

Volume of the hexagonal prism = Area of the base × Height

                                                     = 112.518 × 15.4

                                                     = 1732.7772 ft³

The volume of the hexagonal prism is about 1732.7772 ft³.

b. -0.5 > 0 . . . . . false

c. -1.5 < -0.5 . . . TRUE

d. 1/2 > 0.5 . . . . false (these are the same number) 1/2 = 0.5

_____

In order on the number line from left to right, you will see ...

  (left end) ... -1.5 ... -0.5 ... 0 ... 0.5 ... (right end)

__

The inequality relation appropriate to these is ...

What is the value of the missing angle?a, 720b, 120c, 128d, 138
Zigmanuir [339]
The sum of all the interior angles in a hexagon is 720°, so if you add up all the angles and then take them away from 720, you'll get your answer:
152 + 85 = 237
237 + 85 = 322
322 + 125 = 447
447 + 135 = 582
So 720 - 582 = 138°, which is your answer. I hope this helps!
