Answer:
36 is 25% of 144
Step-by-step explanation:
25% means 25/100 or 1/4. Thus, 36 is 1/4 of 36*4 = 144
Answer:
(My answers are not rounded!)
Problem A:
Area: 285 cm^2
Perimeter: 70 cm
Problem B:
Area: 30 m^2
Perimeter: 30 m
Problem C:
Area: 28 m^2
Perimeter: 24 m
Problem D:
Lateral Area: 150 in^2
2 (l + w) h
= 2 (11 + 4) 5
= 2(15)5
= 30(5)
= 150
Surface Area: 238 in^2
2 (lw + hl + hw)
2 (11 x 4 + 11 x 5 + 5 x 4)
= 2 ( 44 + 55 + 20)
= 2 (119)
= 238
Volume: 220 in^3
Length x width x height (rectangular prism)
use formula: 11 x 5 x 4 = 220
Problem E:
Area: 379.94 m^2
Formula: πr^2 (circle)
3.14(11^2)
= 3.14(121)
= 379.94
Circumference: 69.08 m
Formula: 2πr
= 2(3.14)11
= 6.28(11)
=69.08
Problem F:
Area: 49 m^2
length x width
7 x 7 = 49
Perimeter: 28 m
2 (l + w)
= 2 (7 + 7)
= 2(14)
= 28
Problem G:
Area: 1,056 cm^2
length x width
48 x 22 = 1,056
Perimeter: 140 cm
2 (l + w)
2 (48 + 22)
2(70)
=140
Problem H:
Lateral Area: 94.2 in^2
2πrh
= 2(3.14) x 1.5(10)
= 6.28 x 15
= 94.2
Surface Area: 108.33 in^2
2πrh+2πr2
=2(3.14) 1.5(10) + 2(3.14) 1.5^2
= 108.33
Volume: 70.65 in^3
πr2h
= 3.14(1.5^2) 10
= 3.14(2.25) 10
= (7.065) 10
= 70.65
Given :
A 18-mile taxi ride takes 21 minutes and costs $12.60.
To Find :
The cost of a 39- mile taxi ride. What unit price do you need.
Solution :
Unit price per mile :
Cost of 39 mile taxi ride :
Therefore, unit price is $27.3 and unit price is $0.7 / mile .
Hence, this is the required solution.
Answer:
(6,5), (3,-4) either one of those...
Answer:
Sometimes true
Step-by-step explanation:
This is only true for the numbers 0 and 1 because 0 squared is 0 and 1 squared is 1 making the different of their squares 1 and the difference of the numbers also 1.
For every other number combo this is untrue.
