Answer:

12/18 every hour

Step-by-step explanation:

2/3 =10 minutes

4/6 = 20 minutes

6/9 = 30 minutes

8/12 = 40 minutes

10/15 =50 minutes

12/18 = 60 minutes

Answer:

They need more than 2.5 inches.

Step-by-step explanation:

average = 5.3

June: 6.3

July: 7.1

August: x

The average of the amounts for June, July, and August is

(6.3 + 7.1 + x)/3

To exceed the average, the average must be greater than 5.3.

(6.3 + 7.1 + x)/3 > 5.3

Multiply both sides by 3.

6.3 + 7.1 + x > 15.9

x + 13.4 > 15.9

Subtract 13.4 from both sides.

x > 2.5

Answer: They need more than 2.5 inches.

Answer:

$12.55 per CD

Step-by-step explanation:

If each CD is of equal price, you must then divide the price by the number of CD's. (75.30/6=12.55)

Answer:

$75.30/6 = $12.55 per CD

Step-by-step explanation:

Since the CDs are equally-priced, my thought is that you would divided the quantity that you purchased by your total to get your answer. So, your total, $75.30 divided by, the amount of CDs purchased, 6. This would lead you to the answer $12.55, which is the cost of each CD. To check your answer you would multiply $12.55 by 6 to get $75.30.

Answer:

a. f(1) = -4

b. One value of x for which f(x) = -1 : 2 (or -2)

Step-by-step explanation:

a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.

b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.

I hope you find my answer and explanation to be helpful. Happy studying.

Step-by-step explanation:

The value of the wavelength will be equal to 2 meters.

It is given that a radio is broadcasting at 150 MHz .

We have to calculate the wavelength.

What is the formula for wavelength ?

The wavelength is given by L = c/f , where c = speed of wave and f is the frequency of wave.

∵ L = c/f

Let's assume c = 3 × 10^8

Given that frequency (f) is 150 MHz .

Wavelength (L) is approximately ;

L= (3 × 10^8 )/ (150,000,000)

L= 2 meters

Thus, the wavelength of a radio wave broadcast at 150 MHz will be equal to 2 meters.

Answer:

Things like:

2/9 + 7/9  = 9/9 = 1

3/4 + 1/4 = 4/4 = 1

If the number is the same for the numerator and denominator it adds up to 1.

More examples:

6/10 + 4/10 = 10/10 = 1

9/15 + 6/15 = 15/15 = 1

Answer:

A

D

Step-by-step explanation:

Answer:

●A. (4x + 16)° = 180°

○B. x° = 49°

○C. m<A = 99°

● D. From smallest to largest: <B, <C, <A

The answers are both A and D.

Answer:

Quest 5. No, 2^4 = 16, 2.4 =2 x 4 = 8.

Quest 6. let No. of cells = Nc, let No. of Hours = Nh.

then Nc = (6hrs x 2cells)/1hr = 12 cells.

if 1,024 cells, then

Nh = (1hrs x 1,024cells)/2hrs = 512 hrs.

Quest 7. No, cos 10^7 is only 10,000,000, so 39 & 10 million are not any way equal.

Quest 8. 1 = 1^3, 8 = 2^3, 27 = 3^3, 1 = 1^3, 64 = 4^3, 125 = 5^3,

Quest 9. 2^8 = 2 x 2 x 2 x 2 x 16 = 256, this cos 256 is a product of 8, 2s & there are 4, 2s in 16.

so altogether its all 8, 2s.

2x+3(x-5)=20

2x+3x-15=20

5x-15=20

5x=35

x=7

Answer:

x = 5

Step-by-step explanation:

2x + 3(x - 5) = 20

simplify

5x - 5 = 20

get the variable and the number on different sides

5x - 5 + 5 = 5x

20 + 5 = 25

5x = 25

now divide each side by 5

5x / 5 = x

25 / 5 = 5
