Answer:
0.615
Step-by-step explanation:
Just round up.
$6.90 divided by 3 is $2.30 which is the unit rate and if you multiply $2.30 by 10 you get $23
Answer:
3a+5p= 45
Step-by-step explanation:
If a bag of apples costs $3 and a bag of pears costs $5 and you buy 11 bags that costed 45$, then to find out how many bags you bought for each you would need to set up an equation. I go this equation by a being amount of bags of apples and p being amount of bags of pears. since each bag of apples cost $3 and you do not know how many you got you would use 3 times amount of bags of apples (3a) this would be 3a because each bag costs 3 dollars and since you do not know how many bags of pears you bought you would use 5 times the amount of bags of pears (5p) this would be 5p because each bag of pears costs 5 dollars. It equals 45 because you spent $45 total.
Answer:
74 (square) cm
Step-by-step explanation:
First, to find the surface area of both faces, make each face into two right triangles.
Use the formula A = ab/2 to find the surface area of one of the new right triangles. in this case, A = 2x3.5/2 is equal to 3.5.
Double this to find the full surface area for each face, 7 (square) cm.
Next, find the surface area of the base by multiplying the length by the width. in this case, 4x5 = 20, your base surface area.
Next, find the surface areas of the sides the same way as the base. This example has the same measurements as well. 5x4 = 20.
Last, add all of the solutions together to get the surface are of the whole object. 7 + 7 + 20 + 20 + 20 = 74 (square) cm
Answer:
3:1
Step-by-step explanation:
who did not wear = 28 - 21
= 7
ratio = 21: 7
= 3:1
