C) 120

Step-by-step explanation:

Use three times five and minus one times

you will get 12 and multiply by 10

C. 120

or a faster way to solve these is just 150 (total # of students) and multiply by the percent in decimal form which in this case would be 0.80 (because percentage is out of 100, 80% is 80/100, which is 0.80 as a decimal)

150 • 0.8 = 120!!! :)

Answer:

I believe the answer is D

Step-by-step explanation:

Which of the following equations has no solutions?
A) 2x – 6 = 2x + 8
B) 4x – 8 = 10
C) 5x + 20 = 5x + 20
D) 9x = 9

Answers

Answer: I did the math in my head and I think it’s B

Step-by-step explanation:

Your answer is A.
2x - 6 = 2x + 8
Just looking at this, it doesn’t make sense. Two times a number - 6 cannot equal two times the same number +8.

But solving it mathematically, we want to get the variables on one side of the equation, so we subtract 2x from both sides:
2x - 2x -6 = 8
Then add 6 to both sides:
2x - 2x = 14
0 = 14 is untrue.


The other options’ answers:

B: x = 4.5
4x - 8 = 10
4x = 18
x = 4.5

C: has an infinite number of solutions. Anything you plug into x on one side of the equation you will plug in on the other side. Both sides are identical.

D: x = 1

ZA and ZB are complementary angles. If mZA = (2x + 10)° and m
ZB = (3x + 15)', then find the measure of ZB.

Answers

Answer:

∠ZB = 54°

Step-by-step explanation:

Given:

Pair of complementary angles

∠ZA = (2x + 10)° and m

∠ZB = (3x + 15)

Find:

Measure of ∠ZB

Computation:

complementary angles

a + b = 90°

∠ZA + ∠ZB = 90°

(2x + 10) + (3x + 15) = 90

5x + 25 = 90

x = 13

So,

∠ZB = (3x + 15)

∠ZB = 13(3) + 15

∠ZB = 54°

Which expression models the phrase "Wally mowed two more lawns than he mowed last week"? n + 2 n minus 2 2 minus n 2 n

Answers

Given:

The phrase is "Wally mowed two more lawns than he mowed last week".

To find:

The expression that models the given phrase.

Solution:

Let the number of lawns mowed by Wally last week be n.

We know that, we use plus sign "+" for "more".

If Wally mowed two more lawns than he mowed last week, then the lawns mowed by the Wally this week is the sum of n and 2.

Lawns mowed this week = [tex]n+2[/tex]

The required expression for the phrase "Wally mowed two more lawns than he mowed last week" is n+2.

The prime numbers are: 151, 157, 163, 167

You just need to know what numbers are prime numbers.

Answer:

4 prime numbers

Step-by-step explanation

A prime numbers is a natural number greater than 1 that is not a product of two smaller natural numbers. For example, 5 is a prime number because it is multiplied by 1 and itself. On the contrary, 4 is not a prime number because it is multiplied by 2. Remeber 1 is not a prime number because it has only 1 factor and prime numbers have exactly 2 factors. Therfore the prime numbers in between 150 and 170 are.... 151, 157,163, and 167.

                               

             The 4 prime numbers between 150 and 170 are:

IF ME is a diameter, the length of TE is 6, and the length of MT is 8, what is the EXACT circumference of circle D?

Answers

Answer:

10π

Step-by-step explanation:

Since ME is the diameter of the circle,

angle MTE = 90° (∠ in semicircle)

By pyth. theorem we can obtain,

ME = √8² + 6²

ME = 10

The diameter of the circle is 10

The circumference of circle D is 10π

Answer:

<MTE =90°

the inscribed angle from the diameter is 90°

in triangle MTE

MT=8 unit

TE=6unit

by using Pythagoras law

D=ME=√(8²+6²)=10 unit

radius =D/2=10/2=5unit

circumference of circle D=2πr=2π×5=10π or31.4unit

The volume of a cylinder is 65 cubic centimeters. Which equation can be used to find h, the height of the cylinder?
A. h = 65/b, where B is the base area of the cylinder.
B. h = 65 - B, where B is the base area of the cylinder.
C. h = 65B, where B is the base area of the cylinder.
D. h = B/65, where B is the base area of the cylinder.

Answers

Answer:

Im so sorry for do this but can you help me click my profile pic the click the last question PLZZZZZZZ will give 50 brain  

Step-by-step explanation:

The equation that can be used to find h, the height of the cylinder, is h = B/65. The correct option is D.

How to calculate the height?

The formula for the volume of a cylinder is:

V = Bh

Where V is the volume, B is the base area, and h is the height of the cylinder. We are given that the volume of the cylinder is 65 cubic centimeters, so we can write:

65 = Bh

To solve for h, we can divide both sides of the equation by B:

h = 65/B

Therefore, the equation that can be used to find h, the height of the cylinder, is:

D. h = B/65, where B is the base area of the cylinder.

Given the system of equation 7x-3y = 48 .......Eq 1 2x+ y = 35 ........Eq 2 __________ To solve this system by elimination and multiplication , i can ...............................

Answers

Answer:

x = 11.75

y = 11.5

Step-by-step explanation:

By Elimination Method:

   7x - 3y = 48    ---- (1)

-

   2x + y = 35   -----   (2)

Multiply equation (1) by 2 and equation (2) by 7

   14x - 6y = 96

-

   14x + 7y = 245      

     0   -13y = -149

-13y = -149

y = -149/-13

y = 11.5

From equation (2); replace y with 12

2x + y = 35

2x + 11.5 = 35

2x = 35 - 11.5

2x = 23.5

x = 11.75
