Question

Alan is giving a basic math test in his class. One of the questions in the test is about finding two factors of the number 221. Which are the two factors of the given number? The two factors of the number 221 are ___ and ____.

Solution 1

The two factors of the number 221 are 13 and 17.

A factor refers to a whole number, which fits evenly into another whole number. Thus, factors are the numbers, which we multiply together to get another number. The two numbers that can be multiply together to get 221 are 13 and 17.

A factor refers to a whole number, which fits evenly into another whole number. Thus, factors are the numbers, which we multiply together to get another number. The two numbers that can be multiply together to get 221 are 13 and 17.

Solution 2

1,13,17 are three of them

Question

What is 4.6 repeating as a fraction???
please help!! :'(

Solution 1

Your answer would be 4 2/3.

Let

Let

x=4.66¯6

Then 10x=46.66¯6

So 10x−x=46.66¯6

4.66¯6.−−−−−−−− subtract

9x=42

Divide both sides by 9

x=429=423

Question

What is the approximate volume of a cylinder with a radius of 8 cm and height of 5 cm? A. 62.8
B. 251.2
C. 25.1
D. 502.4
E. 1004.8

Solution 1

V(cylinder)=πr² *h

r=8 cm

h=5 cm

V(cylinder)=πr² *h =3.14*8²*5= 1004.8 cm³

Answer : E.

r=8 cm

h=5 cm

V(cylinder)=πr² *h =3.14*8²*5= 1004.8 cm³

Answer : E.

Question

What is the y-intercept of x^2+2x+6

Solution 1

The y-intercept occurs when x = 0.

y = x^2 + 2x + 6

Let x = 0

y = 0^2 + 2 * 0 + 6

y = 6

Answer: 6

y = x^2 + 2x + 6

Let x = 0

y = 0^2 + 2 * 0 + 6

y = 6

Answer: 6

Solution 2

Y-intercept is a point when x=0,

so

y=x²+2x+6=0²+2*0+6=6

y=6

So y-intercept is (0,6)

so

y=x²+2x+6=0²+2*0+6=6

y=6

So y-intercept is (0,6)

Question

6x – 2y = 10 2x + 3y = 51 Solving the first equation above for y gives

Solution 1

**Answer with Step-by-step explanation:**

6x – 2y = 10

2x + 3y = 51

Solving the first equation above for y:

6x-2y=10

⇒ 2y=6x-10

dividing both sides by 2

**y=3x-5**

Putting value of y in second equation

2x + 3(3x-5) = 51

2x+9x-15=51

11x=51+15

11x=66

⇒ x=6

y=3×6-5

=18-5

= 13

**Hence, solution is: x=6 and y=13**

**and Solving the first equation above for y gives: y=3x-5**

Solution 2

The answer is

**x=****6 and ****y****=****13**

Question

Hello everyone, please explain this with details. Jay traveled from Miami to Jacksonville, a distance of 320 miles. He left Miami at 8:00 A.M., stopped for lunch for 30 minutes, and stopped for two 15 minute breaks at rest
areas. He arrived in Jacksonville at 2:15 P.M. What was his average rate of speed during
his travel time?

Solution 1

Travel from 8 AM to 2:15 PM is a total of 6 hours and 15 minutes. If you subtract the 30 minute lunch and two 15 minute breaks you are left with 5 hours and 15 minutes or 5.25 hours. To get his average speed divide 320 miles by 5.25 hours

320 ÷ 5.25 = 60.9 mph or 61 mph rounded to the nearest one.

320 ÷ 5.25 = 60.9 mph or 61 mph rounded to the nearest one.
