Use the equation .8x + x = 252
x is the number, and .8 is the decimal equivalent of 80%.
1.8x = 252
x = 140
Answer:
A
Step-by-step explanation:
The volume (V) of a pyramid is
V =
area of base × perpendicular height (h)
area of square base = 4² = 16 and h = 4, hence
V =
× 16 × 4 =
= 21
ft³
Answer:
D
Step-by-step explanation:
because when x = -2 on the graph the y is -2 (-2,-2)
when the x values is 0 the y value is 1 (0,1)
and when x is 1 the y value is 2. (1,2)
hope this helps. have a good day
Answer:
- cos(A) = 3/5
- cos(B) = 0
- cos(C) = 4/5
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between the cosine of an angle and the sides of the triangle.
Cos = Adjacent/Hypotenuse
__
<h3>Angle A</h3>
In the given triangle, the hypotenuse is AC. The side adjacent to angle A is AB, so its cosine is ...
cos(A) = AB/AC
cos(A) = 3/5
__
<h3>Angle B</h3>
The right angle in the triangle is angle B. The cosine of a right angle is 0.
cos(B) = 0
__
<h3>Angle C</h3>
The side adjacent to angle C is CB, so its cosine is ...
cos(C) = CB/AC
cos(C) = 4/5
