Answer 1

Arthur and Austin have triangular gardens in front of their houses, as shown below.

Two houses are shown one marked as Arthur’s house and the other marked as Austin’s house. The houses are shown as rectangles with same length of 70 feet each and different width. Both the houses are shown to have triangular gardens in the front at right angles to the length of the house. The angle formed between the length of the house and the hypotenuse of the triangular garden is shown equal for both Austins and Arthur’s house by way of hash marks.

If the garden in front of Arthur’s house has an area of 1400 square feet, what is the width x of the garden in front of Austin’s house?

10 ft

Answer 7

A wooden pyramid, 9 inches tall, has a square base. A carpenter increases the dimensions of the wooden pyramid by a factor of 4 and makes a larger pyramid with the new dimensions. Describe in complete sentences the ratio of the volumes of the two pyramids.

Answer 8

nd I need help like really fast cuz my time is almost up on my quiz

Answer 9

since each of the dimension of the new pyramid is larger by a factor of 4, the side of new pyramid's square base would be 4 times larger, and the new pyramid's height also would be 4 times larger.

Answer 10

we have the formula for volume of square pyramid = 1/3 s^2 * h

volume of new pyramid = 1/3 (4s)^2 * (4h)
= 1/3 4^3 *s^2 * h
= 4^3 * 1/3 s^2 * h
= 4^3 * volume of original square pyramid

Answer 11

so the volume of new square pyramid would be 4^3 = 64 times larger than the original pyramid.
