Answer:
x=4
Step-by-step explanation:
You do a^2 x b^2 = c^2
so 5^2 x ? = 10^2
25 x ?= 100
?= 100/25
?= 4
Answer: a
Step-by-step explanation:
The graph has a vertex at x=3, so eliminate d and e.
The graph's vertex is at x=1, so eliminate c.
The graph opens upward, so eliminate b.
let's firstly convert it to an improper fraction.

Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle (
).
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
Answer:
<h2>Net proceed= s-0.98nd-11</h2>
Step-by-step explanation:
Given that the shares cost $d
n shares will be =$dn
paid 2% commission to her broker= (2/100)*nd= 0.02nd
sold the share for $s
paid a fee of $11
Her net proceeds algebraically will be
Net proceed= s-nd-11-0.02nd
collect like terms
Net proceed= s-(nd-0.02nd)-11
Net proceed= s-0.98nd-11
