Answer:

#1

  • 30% of 70 ⇒ 0.3*70 = 21
  • x% of 84 = 21
  • x*84/100 = 21
  • x = 2100/84
  • x = 25%

#2

  • 75% of 36 = x% of 58
  • 0.75*36 = 0.58x
  • 0.58x = 27
  • x = 27/0.58
  • x = 46.55%

#3

  • 1/2 of 3/5 ⇒ 1/2*3/5 = 3/10
  • 3/10 of 20 days ⇒ 3/10*20 = 6 days

Cerrena [4.2K]
If I understand correctly, just substitute 15 for C in f = 1.8c + 32, then solve for F
-------------------
f=<span><span>(1.8)(15)</span>+<span>32
</span></span>------------
Simplify
f=<span><span><span>(1.8)</span><span>(15)</span></span>+<span>32
</span></span>f = 27 + 32

Find a so that the point (-1, 2) is on the graph of f(x)=ax^2+5.
Gnesinka [82]
We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3
