Note: Consider x be the breadth of the box.
Given:
The surface area of the box is 204.25 square feet.
Length of the box = 10 ft
Breadth of the box = x ft
Height of the box = 6.5 ft
To find:
The value of x.
Solution:
The surface area of a cuboid is:
Where, l is length, b is breadth and h is height of the cuboid.
Putting 
in the above formula, we get
Using distributive property, we get
Divide both sides by 33.
Therefore, the correct option is B.
a. irrational numbers
This is because irrational numbers are number like pi and non perfect square roots, etc
Answer:
D
Step-by-step explanation:
To find the answer,we can set an equation:
Let the time he used to drive in the afternoon be y miles.
Time used in the afternoon = y
Time used in morning = y - 70
Total time used = 248
The value of y:
y + (y - 70) = 248
2y-70 = 248
2y = 248+70
2y = 318
y = 318/2
y = 159
Therefore, he droved 159 miles in the afternoon.
Hope it helps!
Answer:
- $17,500 at 14%
- $16,000 at 12%
Step-by-step explanation:
Let x represent the amount loaned at 14%. Then the total interest earned is ...
0.14x +0.12(33,500 -x) = 4,370
0.02x = 350 . . . . . . . . . . subtract 4020 and simplify
x = 17500 . . . . . . . . . divide by 0.02
The amount loaned at 12% is $33,500 -17,500 = $16,000.
$17,500 was loaned at 14%
$16,000 was loaned at 12%
