Answer:
radius = 6.15
Step-by-step explanation:
cuz ik can u mark me brainliest?
To figure out the interior angles you multiply the number of sides minus 2 by 180 so for a triangle there are 3 sides so you minus 2 to get 1 multiply it by 180 and you get 180 which is the interior angles of a triangle so to do this one you minus 2 from 6 to get 4 multiply it by 180 and you get 720 degrees
So 3/4 of an hour is 45 minutes (3/4 × 60min)
1/3 of 45 minutes is 15 minutes (1/3 × 45min)
Then for 5 walls, he will take 5 × 15 = 75 minutes
Answer: He will take 1 hour 15 minutes to paint 5 walls
1: because it is a rectangular you can find the area by using this equation:
A = b*h
2: So you know that 180 feet is for three sides of the garden:
180 = 2h+b --> b = 180-2h
and you also know that:
A = b*h = (180-2h)*h
If you differentiate (solve A'=0) for this equation, you will find that h=45.
Therefore b must be equal to 90.
3: the greatest area is therefore A = 90*45 = 4050
I hope that helped.
Answer: B
. $23.42 is your answer
Hailey went to Frank’s Market and bought 1 3/4 pounds of coffee at $13 a pound and 8 1/2 pounds of rice at $0.45 per pound. If Hailey paid for her purchase with a $50 bill, how much change did she receive?
Answer:
$23.43
Step-by-step explanation:
First, you need to find the total amount she needs to pay for the items she purchased:
1 3/4=1.75
8 1/2=8.5
Total purchase=(1.75*$13)+(8.5*$0.45)
Total purchase=22.75+3.82
Total purchase=26.57
No, you need to subtract the total amount you have to pay for your purchase from $50:
$50-$26.57=$23.43
According to this, the answer is that she received $23.43 as change.
