she walked 1 week at one-half her regular
rate for 4 hours. write and evaluate a
numerical expression to find the total
number of miles hailey walked last month.

Hailey walked 70 miles last month.

Step-by-step explanation:

Consider the provided information.

Hailey walks at an average rate of 3.5 miles  per hour.

She walked 3 weeks  at her regular rate for 6 hours per week.

Hence, she walk 63 miles in last 3 weeks.

She walked 1 week at one-half her regular  rate for 4 hours.

Half of her regular  rate is

Therefore, the distance covers

The sum of distance is: 63+7=70

Hailey walked 70 miles last month.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
