Answer:
<u>f(5) = -45</u>
Step-by-step explanation:
f(x) = -5(x + 4)
<h3>f(5)</h3>
f(5) = -5(x + 4)
f(5) = -5(5 + 4)
f(5) = -5(9)
f(5) = -45
C) 22
86/4 = 21.5
*5 Or more, raise the score*
(rounds to 22)
you should have 2 lightbulbs left over but you would be 2 lightbulbs short if you were to get 21 packages as opposed to 22
X = 25 +4*(90 -x) . . . . . x is 25 more than 4 times its complement
x = 385 -4x . . . . . . . . . eliminate parentheses
5x = 385 . . . . . . . . . . . .add 4x
x = 77 . . . . . . . . . . . . . . divide by 5
The measue of angle x is 77°.
Answer:
- Angle E corresponds to angle L
- The two triangles are similar
Step-by-step explanation:
<u>Angle E corresponds to angle L</u> because <u>the two triangles are similar</u> (and we know this becuase corresponding sides are proportional.
Answer:
V = 10,240mm^3
Step-by-step explanation:
The volume of pyramid is given by the following formula:
(1)
b: base of the pyramid = (32mm)^2
h: height
Thus, it is necessary to find the value of h, by using the Pitagoras's theorem, one half of the base and the slant height (which forms a rectangle triangle with h):
by replacing in (1) you obtain:
hence, the volume is 10240mm^3
