Answers

Answer 1

Answer: i dont know what the question is but the answer is 1/5 of an hour
720sec/60sec=12mins
then you do 12mins/60mins= .2hr or 1/5 of an hour

hope that kind of helped

the refreshment stand at the fair was open for 3 hours four people took turns working at the stand for the same amount of time how many minutes did each person work

Answers

first off, simplify 3 hours. One hour is equal to 60 minutes, so we get 180 minutes. Next we divide 180 by four. We can make this easier by dividing 180 by ten, and multiplying it by 10 after we do everything. 4 times 4 is 16, and then the remaining 2 divided by 4 is .5. We have 4.5, but now we need to multiply 4.5 by 10, and we get 45. The answer is 45.

13) v2 - 110 + 18 = 0
14) 5x7 - 12x +7 = 0
Solve by factoring

Answers

Answer:

see explanation

Step-by-step explanation:

(13)

v² - 11v + 18 = 0 ← in standard form

(v - 2)(v - 9) = 0 ← in factored form

Equate each factor to zero and solve for v

v - 2 = 0 ⇒ v = 2

v - 9 = 0 ⇒ v = 9

solutions are v = 2, v = 9

(14)

5x² - 12x + 7 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 7 = 35 and sum = - 12

The factors are - 5 and - 7

Use these factors to split the x- term

5x² - 5x - 7x + 7 = 0 ( factor the first/second and third/fourth terms )

5x(x - 1) - 7(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(5x - 7) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

5x - 7 = 0 ⇒ 5x = 7 ⇒ x = $(7)/(5)$

solutions are x = 1, x = $(7)/(5)$
