Tresset [83]

Answer:

45 degrees

Step-by-step explanation:

A straight line is an angle with a measure of 180°, but becasue it looks like we have two angles that create the 180° angle, therefore, it is a supplementary angle.

Knowing this

2X = 90° (right angle)

so (2X) + (2X) = 180° (supplementary angle)

Therefore, to find X you can do

2X = 90

divide by 2 on both sides (to isolate the variable we are trying to find which is X)

and you get....

X= 45 becasue 2 times 45 equals 90

answer: X=45°

Answer:

m < Q = 40°

m < M = 60°

Step-by-step explanation:

1.) All angles in every triangle altogether equal 180°

From the 4 measurements, you can tell angle Q and S are equal in order to make all angles equal 180 and those angles to be equal (below)

180 - 100 = 80

80/2 = 40

2.) This is an isoceles (all angles and sides are equal) There are three angles (divide 180 by 3)

180/3 = 60

The average salary for a teacher is $55,000 per year. A physician makes on average $220,000. If you consider the earning potenti

Evgen [1.6K]

Answer:

The difference between the teacher's earnings as compared to the physician's earning over 30 years is $4,950,000

Step-by-step explanation:

Given as :

The average salary for a teacher in a year = $55,000 per year

The average salary for a physician in a year = $220,000 per year

Let The difference between the teacher's earnings as compared to the physician's earning over 30 years = $x

Now,

The average salary for a teacher for 30 years = $55,000 × 30 = $1,650,000

The average salary for a physician for 30 years = $220,000 × 30 = $6,600,000

So,

The difference between the teacher's earnings as compared to the physician's earning over 30 years = The average salary for a physician for 30 years - The average salary for a teacher for 30 years

Or, $x = $6,600,000 - $1,650,000

∴ x = $4,950,000

So, The difference between the teacher's earnings as compared to the physician's earning over 30 years = x = $4,950,000

Hence, The difference between the teacher's earnings as compared to the physician's earning over 30 years is $4,950,000 . Answer

Fourteen out of 20 teens said they eat breakfast every morning what is a reasonable prediction for the number of teens out of 12

Oksi-84 [34.3K]

Answer:

896

Step-by-step explanation:

14 of 20 teens eats breakfast every morning.

The percentage of those who eat breakfast every morning

= 14/20 x 100%

= 0.7 x 100%

= 70%

So, 70% of 20 teens eat breakfast every morning.

The reasonable prediction for the number of teens that eats breakfast every morning from 1280 teens will be 70% of 1280.

70/100 x 1280

0.7 x 1280

896

The prediction would be 896 out of 1280 teens eats breakfast every morning
