Step-by-step explanation:
I divided 4.5 by 32 to get how many miles she runs in a minute (.1406) then I multiply it by 54 to get how many she runs in 54 minutes.
Answer:
whats the question? not enough info
Sum of two angles that are complementary = 90°
<em>m</em>∠1 + <em>m</em>∠2 = 90°
Given :
<em>m</em>∠1 = 12°
Then :-
<h2>∴ <em>m</em>∠2 = 78°</h2>
Expression that represents the change from $20 after the purchase of an item that costs d dollars is:
20-d
K² + 13k + 30 = 0
This is a quadratic equation. Let's attempt solving it by factorization.
Coefficient of k² = 1, last term = 30
Multiply these two together 1*30 = 30
We think of two numbers that multiply to give 30 and add to give the middle term 13.
The two numbers are 3 and 10.
3*10 = 30, 3 + 10 = 13.
we replace the 13k with 3k + 10k
k² + 13k + 30 = 0
k² + 3k + 10k + 30 = 0
k(k + 3) + 10(k + 3) = 0
(k + 3)(k + 10) = 0
(k + 3) = 0 or (k + 10) = 0
k = 0 - 3 or k = 0 - 10
k = -3, or -10
I hope this helps.
