Eddi Din [679]

Answer:

She must work at least 7 hours. All possible values are 7, 8, 9, 10

Step-by-step explanation:

14 - 4 = 10

4($7)=$28

$130-$28=$102

$102÷$15=6.8

$15x7=$105

$105+$28=$133

$15x8=$120

$120+$28=$148

$15x9=$135

$135+$28=$163

$15x10=$150

$150+$28=$178

10(5 - n) - 1 = 29<br><br> n = ?<br> Help!

nydimaria [60]

n = 2

distribute and simplify left side of equation

50 - 10n - 1 = 29

49 - 10n = 29 ( subtract 49 from both sides )

- 10n = 29 - 49 = - 20

n = $\frac{-20}{-10}$ = 2

The functionâ€‹ s(t) represents the position of an object at time t moving along a line. Suppose s (3 )equals 156 and s (6 )equa

bixtya [17]

Answer: The average velocity of the object over the time interval [3,6] is 20.

Step-by-step explanation:

Since we have given that

s(3) = 156

s(6) = 216

We need to find the average velocity over the time interval [3,6].

So, average velocity becomes

$\dfrac{s(t_1)-s(t_0)}{t_1-t_0}\\\\=\dfrac{s(6)-s(3)}{6-3}\\\\=\dfrac{216-156}{3}\\\\=\dfrac{60}{3}\\\\=20$

Hence, the average velocity of the object over the time interval [3,6] is 20.
