Answer:
8
Step-by-step explanation:
A^2 + B^2 = C^2
36+?=100
100-36= 64
Square root of 64 is 8
Answer:
The area is 72 cm².
Step-by-step explanation:
Since it is equivalent triangle
h = b
so,
b + b + b (since all sides are equal)= 36 cm
3b = 36 cm
or, b = 36/3
so, b = 12 cm
so
area of triangle = (1/2)×b×h
= (1/2)×12cm×12cm
= 6cm × 12cm
= 72 cm²
The answer is B
5*5 = 25
25-5 = 20
Answer: $3.25
Step-by-step explanation:
First you need to calculate the cost of the 8 pounds of nuts.
Cashews = 4 x $4 = $16
Peanuts = 4 x $2.50 = $10
The total cost of 8 pounds of nuts equals $16 + $10 = $26
In order to calculate the cost of 1 pound of the mixture you need to divide the total cost by the total weight.
$26 / 8 lbs = $3.25 / lb
The cost of one pound of the mixture is $3.25.
