PLEASE HELP I WILL GIVE BRAINLIEST!! Mike and his sister did some laundry at the laundromat. To wash a load costs $2 and to dry a load costs another $2. Mike and his sister washed and dried 4 loads of laundry. They also had to buy 4 packets of detergent for $1 per packet. How much money did Mike and his sister spend to do their laundry?
a) $16
b) $28
c) $12
d) $20

answer is d) $20

Step-by-step explanation:

because 2x4=8 + 2x4=8 = $16 then 4 packets for $1 is $4 16+4= $20

D) $20

Step-by-step explanation:

Wash plus dry = $4

$4 times 4 times = $16

$1 for one detergent times the four packets = $4

Total is $20

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
