Answer:

$\frac{4}{20} = \frac{5}{x} \\ 4 \times 20 = k \\ 5 \times x = k \\ 4 \times 20 = 5x \\ 80 = 5x \\ \frac{80}{5} = \frac{5x}{5} \\ x = 16$

it get <u>16</u> hours.

I need homework help! Its proportions, but the thing is, I'm terrible at them. All I know is that is/of=x/100.

masha68 [24]

19) 15/a = 3/2

Start by cross multiplying....

3a = 30

Divide both sides 3

a = 10

21) 2/7 = 4/d

2d = 28

   d= 14

23) 8/p = 3/10

80 = 3p
p = 26.66

25) 2 / -5 = 6/t
  2t = -30

  t = -15

I need help solving problem 11.

Lunna [17]

Since triangle ABC is isosceles, then angles 1 and 9 are congruent.

4x + 3 = 9x - 47

-5x = -50

x = 10

m<1 = 4x + 3 = 40 + 3 = 43

m<1 = m<9 = 43

Triangle DBE is equilateral, so it is also equiangular.

m< 4 = m<5 = m<6 =60

Angles 3 and 8 are supplementary to congruent angles that measure 60 deg, so 180 - 60 = 120, so

m<3 = m<8 = 120

For angles 2 and 7, use the sum of the measures of the angles of a triangle is 180 deg.

m<1 + m<2 + m<3 = 180

43 + m<2 + 120 = 180

m<2 + 163 = 180

m<2 = 17

m<2 = m<7 = 17

The radii of two circles are in the ratio of 3 to 1. Find the area of the smaller circle if the area of the larger circle is 27

Naddik [55]

ANSWER
$3\pi sq.\: in.$

EXPLANATION

Let R be the radius of the bigger circle and r, be the radius of the smaller circle.

Then their ratio is given as,

$R:r=3:1$

We can rewrite it as fractions to get,

$\frac{R}{r} = \frac{3}{1}$

We make R the subject to get,

$R = 3r$

The area of the bigger circle can be found using the formula,

$Area=\pi {r}^{2}$

This implies that,

$Area=\pi ({3r})^{2}$

$Area=9\pi {r}^{2}$

But it was given in the question that, the area of the bigger circle is 27π.

$27\pi=9\pi {r}^{2}$

We divide through by 9π to get,

$3 = {r}^{2}$

This means that,
$r = \sqrt{3}$

The area of the smaller circle is therefore

$= \pi {( \sqrt{3}) }^{2}$

$= 3\pi$
