Answer:
I might be wrong but i looked it over, and I think the answer can be B
Step-by-step explanation:
I dont know for sure but i think it might be.
Think of the 13-ft length of the ladder as the hypotenuse of a right triangle. Represent the horiz. distance from foot of ladder to base of tree by x, or 5 ft.
Represent the vert. dist. from base of tree to top of ladder by y, which is unknown.
Then (13 ft)^2 = (5 ft)^2 + y^2, or
169 ft^2 = 25 ft^2 + y^2. This simplifies to y^2 = 144. Thus y = + 12 feeet.
Note: Please pay attention to your spelling: "lader i up agenst a tree" should be "the top of a 13-ft ladder is placed against a tree."
Answer:
= 20 ft
Step-by-step explanation:
The perimeter is found by
P = 2(l+w)
= 2(6+4)
=2(10)
= 20 ft
Answer:
What is the circumference of a circle whose radius is 20 feet? Leave answer in terms of π.
A) 10π feet
B) 20π feet
<u>
C) 40π feet </u>
D) 100π feet
Step-by-step explanation:
circumference = 2πr
circumference=2×π×20
circumference=40π
Answer:
A. Cube A
Given:
Cube A volume = 5832 in³
For Cube B dimension in inches:
So Volume of Cube B:
L × B × H = 14.4 × 12 × 12 = 2073.6 in³
Cube A has a larger volume that Cube B.
