The complement of an angle is $5^{\circ}$ more than four times the angle. what is the number of degrees in the measure of the an

Anna11 [10]

Answer:

17°

Step-by-step explanation:

Let x represent the measure of the angle.

(90 -x) = 5 + 4x . . . . the complement is 5° more than 4 times the angle

85 = 5x . . . . . . . . . . add x-5 to both sides

17 = x . . . . . . . . . . . . divide by 5

The measure of the angle is 17°.

Tomika uses 6 1/9 inches of wire to make a necklace and 3 1/3 inches of wire to make a bracelet. How many necklace and bracelet

ser-zykov [4K]

One necklace and bracelet set is equal to 6 1/9 inches + 3 1/3 inches. That makes the total amount of wire in one set to be 9 4/9 inches. If you divide 28 1/3 by 9 4/9, you get 3.
85/3 * 9/85 = 255/85 = 51/17 = 3

Taya2010 [7]

Answer:

The probability that the person will not be a senior

P(E⁻) = 1 - P(E)

= $1- \frac{5}{9} = \frac{4}{9}$

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given A high school club has 10 members who are seniors and 8 members who are juniors

n(S) = 10 + 8 = 18

If a member is randomly selected to be the club president

Let 'E' be the event that the person will be a senior

The probability that the person will be a senior

$P(E) = \frac{n(E)}{n(S)}$

$P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}$

The probability that the person will not be a senior

P(E⁻) = 1 - P(E)

= $1- \frac{5}{9} = \frac{4}{9}$

What is the area of the shaded region to the nearest tenth?

Aleks04 [339]

Answer:

15.1

Step-by-step explanation:

We know that the area of the circle is $\pi r^{2}$ , but we are looking for the portion of the circle, this means we multiply it by the portion of the circle that is shaded.

Area of shaded region = $\pi r^{2} (\frac{x}{360} )$

where r = 4 and x = 108, the 360 comes from the fact that the total degrees around the circle is 360, so dividing the total amount of degrees by the angle will give us the portion we are looking for.

Area of shaded region = $\frac{108}{360} \pi 4^{2}$ = 15.1

Another way to think about it is that the area of the total circle is $\pi r^{2}$ , multiplying it by a fraction, a number less than 1, would give us a smaller value.

Hope this helps.
