88 Is 20 percent of what number?
ValentinkaMS [17]

Answer:

  440

Step-by-step explanation:

You can write the problem statement in math terms as ...

  88 = 0.20 × (what number)

To solve this, divide by the coefficient of the variable, 0.20.

  88/0.20 = (what number)

  440 = (what number)

The number you're looking for is 440.

_____

Of course you know that 20% = 20/100 = 0.20.

(% is a shorthand way to write /100.)

If ∠3 and ∠4 are complementary angles, m∠3 = (x+24)°, and m∠4 = x°, then find the measures of ∠3 and ∠4.
kobusy [5.1K]

Answer:

\huge\boxed{3 = 57 \textdegree}

\huge\boxed{4 = 33 \textdegree}

Step-by-step explanation:

When two angles are complementary, their angle lengths add up to 90°.

Therefore, we can make the equation

(x+24) + (x) = 90

Now we can solve for x.

  • 2x+24=90
  • 2x=66
  • x = 33

Since the measure of ∠4 is just x°, and we know x is 33, that means ∠4 is 33°.

We also have the expression for ∠3, x+24. Since we know x is 33, we can substitute it into the expression.

33+24\\\\57

Hope this helped!
