Answer:

30°

Step-by-step explanation:

If the measure of the arc KL is 25°, then the central angle KOL has measure 25° and the inscribed angle KML subtended on the arc KL has the measure 12.5°.

If the measure of the arc MJ is 85°, then the central angle MOJ has measure 85° and the inscribed angle MLJ subtended on the arc MJ has the measure 42.5°.

Thus, the measure of the angle ELM is 180°-42.5°=137.5°.

Consider triangle EML. In this triangle,

m∠MEL=180°-137.5°-12.5°=30°.

Thus, m∠MEJ=30°.

Find the value of x so that the function has the given value.

For h(x) = -7x + 10, x =1

For r(x) = 4/5x+ 7 , x = -15

Step-by-step explanation:

in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values

So,

h(x) = -7x + 10; h(x) = 3

$h(x) = -7x+10\\3 = -7x+10\\3-10 = -7x+10-10\\-7 = -7x$

Dividing both sides by -7

$\frac{-7x}{-7} = \frac{-7}{-7}\\x = 1$

r(x) = 4/5x+7; r(x) = -5

$r(x) = \frac{4}{5}x +7\\-5 = \frac{4}{5}x +7\\-5-7 = \frac{4}{5}x\\-12 = \frac{4}{5}x\\x = -12 * \frac{5}{4}\\x = -15$

In the last 6 years the population of Manchester, England, has grown at a rate of 0.8% per year to 530,300. If this rate continu

Rzqust [24]

Given parameters:

Current population = 530,300 people

Growth rate = 0.8% per year

Unknown

Population in 15 more years = ?

To solve this problem, we must compound the increase per year.

This implies that we treat the problem like that of a compound interest.

Since we know that population increases by 0.8%,

it is similar to 1 + $\frac{0.8}{100}$ = 1.008 increase

Now the population in 15years will be;

530300 x (1.008)¹⁵ = 597626 people

So, the population after 15yrs is 597626 people

What is the degree measure of FEG? A 20° B 31° C 56° D 124°

Blizzard [7]

Answer:

C) 56

Step-by-step explanation:

DEG and FEG are on a straight line forming 180 degree.

Set your formula up as

180 = (3x+31)+(2x-6)

180 = 3x +2x +31 - 6

180 - 31 + 6 = 5x

155 = 5x

155/5 = x

31 = x

Now substitute 31 in place of x

FEG = (2*31-6)

FEG = 56

What is 3/4 of 4/5. Plz help

Dmitriy789 [7]

Answer:

3/5

Step-by-step explanation:

We want to find 3/4 of 4/5.

The keyword of tells us that we need to multiply. Therefore:

$\frac{3}{4}\times\frac{4}{5}$

Multiply:

$=12/20=3/5$

So, 3/4 of 4/5 is 3/5.

We can confirm this by converting them to decimals.

4/5 is 0.8.

3/4 is 0.75.

0.75 or 75% of 0.8 is indeed 3/5 or 0.6.
