<u>Complete Question: </u>

Janet completed this entire column of math homework in 10 minutes. How many seconds per question did Janet spend?

BTW there is 8 questions in the row

<u>Answer: </u>

Janet spent 75 seconds on each of 8 question

<u>Step-by-step explanation:</u>

We know, every 1 minute consists of 60 seconds. In question, given as 10 minutes. So, it can be expressed in seconds as below,

1 minute = 60 seconds

Hence 10 minutes = 10 (60) = 600 seconds

Let’s consider ‘x’, the time spent on every single question by her.

To find the time spent by Janet on each question, divide 600 seconds by the number of questions she did.

Divide 600 by the number of questions, generally the equation can be formed as ,

           \frac{600}{\text { number of questions }}= 'x' seconds per question

If the number of question is ’8’, then

          'x' seconds per question =\frac{600}{8}=75 seconds

Hence, Janet spent 75 seconds on each of 8 question

Find the center and radius of the circle represented by the equation below.
valina [46]

Answer:

radius 4

center (3,6)

Step-by-step explanation:

(x - h)^2 + (y - k)^2 = r^2

coordinates of the center (h, k) and the radius is (r)

x² + y²- 6x - 12y +29=0

x² - 6x + y²- 12y +29=0

(x² - 6x) + (y²- 12y) +29=0

complete the square

(x² - 6x) + 9 + (y²- 12y) +36 +29=  + 9  +36

(x² - 6x + 9) + (y²- 12y + 36) = + 9  +36 -29

(x-3)^2 + (y-6)^2 = 16

(x - h)^2 + (y - k)^2 = r^2

coordinates of the center (h, k) and the radius is (r)

center (3,6)

radius 4

Hello!

\large\boxed{x^{2} + x - 3 + \frac{4}{2x+3}}

**Process pictured below**

When dividing, find how many times the first time in the divisor (2x + 3) fits into the first time of the dividend (2x³ + 5x² - 3x - 5). In this step, it fits x² times.

Multiply x² by the terms in the divisor and subtract from the dividend. Bring down the next term in the dividend to continue the process.

Repeat this step until you reach the last number. In this case, there was a remainder of 4. In order to write the remainder, you must express it over the divisor which makes it 4 / 2x + 3.

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
boyakko [2]
452.16 = 3.1416 r^2
r^2 = 452.16  /  3.1416
r^2 = 143.93
r = 11.997

C = 2 (3.1416) (12) =75.38 m

In a police chase on the interstate, the suspect’s car reached a speed of 88 miles per hour for a total 15 minutes. In that time
Klio2033 [76]

Answer:

22 miles

Step-by-step explanation:

time must be in hours, hence

15 minutes = \frac{15}{60} = \frac{1}{4} hour

distance = 88 × \frac{1}{4} = \frac{88}{4} = 22 miles
