Which cannot be the angle measurements of triangle ABC? OmZA = 55°, mZB = 65°, mZC = 60°
Mashutka [201]

Answer:

Last option is the correct answer.

m\angle A = 61°, m\angle B = 57°, m\angle C = 61°

Step-by-step explanation:

Since, 61° + 57° + 61° = 179° < 180°

Therefore,

m\angle A = 61°, m\angle B = 57°, m\angle C = 61° cannot be the measurements of triangle ABC.

How do I round 0.3 to the nearest thousandth
Luda [366]
0.3 is 3 tenths.
The order of "ths" is tenths, hundredths, thousandths.
Since there are no numbers after the 3, you simply have to add 2 zeros to make it 300 thousandths.

A circular disc has a circumference of 16pi meters. if we multiply the radius of the circular disc is by 10, what is the circumf
Flauer [41]

The circumference of the new disc 160Π that is 10 time of old circumference.

Step-by-step explanation:

Given,

Circumference of circular disc = 16Π (pi = Π)

Let, the radius of the circle be 'r'

Formula

The circumference of a circle with r radius = 2 Π r

According to the problem,

2 Π r = 16Π

or, 2r = 16 ( by eliminating the value of Π from both the side)

or, r = 8

Now, we multiply the radius by 10

so, the new radius is 8 X 10 = 80

Now the circumference = 2 Π X 80

= 160Π

Hence, the new circumference also will be 10 times of the older one.

Melinda and Marcus each have a job. Melinda earns $12 an hour. She also receives a $75 weekly bonus.
Olenka [21]
According to given information,
Equation of Melinda Earning = 75 + 12x
Equation of Marcus Earning = 15x
Where, x = Number of hours they worked.

Now, we need to calculate when they will have same amount of money, so for that instance they shall equal to each other.
75 + 12x = 15x
15x - 12x = 75
3x = 75
x = 75/3
x = 25

After 25 hours, they will have the money = 15(25) = $375

So, your final answer is $375

Hope this helps!
