Each box is 20 inches long, 30 inches wide, and 20 1/2 inches in hieght.
What is the volume of the box?
Answer:
Volume = 12,300
Step-by-step explanation:
20 x 30 = 600
600 x 20.5 =12300
Answer:
Volume of the box is length ×breadth×height
[tex]20 \times 30 \times 20 \frac{1}{2} \\ = 600 \times \frac{41}{2} \\ = 12300[/tex]

The volume of a cuboid is 140 cm
The area of its base is 88 cm2. Then
its height is
5cm
6 cm
8 cm
7 cm
Volume of cuboid =l×b×h
area of base of the cuboid =l×b
hence
volume of cuboid is = area of base × height
140=88×h
h=140÷88
h=5

Chirstine baked a pumpkin pie. She ate 1/6 of the pie. Her brother ate 1/3 f it ang gave leftovers to his friends. What fraction of the pie did he give to his freinds?
Answer:
1/2
Step-by-step explanation:
Let the total pie be 2
She ate 1/6
Her brother ate 1/3
If she gave her Friend the remaining, the fraction of the amount her friend collected is expressed as:
1-(1/6+1/3)
= 1-((1+2)/6)
= 1-3/6
= 1 - 1/2
=1/2
Hence the fraction she gave her friend is 1/2

The value of the angle,x=50.531°. The angle is obtained by the sin law.
What is the triangle?A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
From the sin rule;
[tex]\rm \frac{AB}{sin \angle ACB} =\frac{BC}{sin \angle BAC} \\\\ \rm \frac{5.6}{sin \angle ACB} =\frac{9.3}{sin \angle 50^0} \\\\ \angle ACB=27.49^0[/tex]
For the same angles;
[tex]\rm \angle ACB=\angle BCD[/tex]
From the exterior angle theorm ;
[tex]\rm \angle BCD+\angle CBD= \angle ADB[/tex]
∠CBD=x
∠ABD=78°
Putting the obtained values;
27.469°+x=78°
x=78°-27.469°
x=50.531°
Hence,the value of the angle,x=50.531°.

What is the approximate average rate of change for f(x) = 20(0.5) from
x = 2 to x = 2?
Answer:
It is: (f(2) - f(0))/(2 - 0)
f(2) = 250(0.5)(2) = 250
f(0) = 250 (0.5)(0) = 0
So: (250 - 0)/(2 - 0) = 250/2 = 175
The average rate of change is 175.

simplify 1/2 (4x+2) - (-2x)
Answer:
4x + 1 is the simplified expression
Step-by-step explanation:
We have to use order of operations in order to solve. We basically need to simplify it with multiplication and addition.
The first step involves mulitplication and distribution property:
1) Do 1/2(4x + 2). If you use distribution property, it would be 1/2(4x) + 1/2(2)
2) Then use multiplication 1/2(4x) is 2x (since 4 multiplied by 1/2 is 2) and 1/2(2) is 1 (since 1/2 times 2 is 1).
Bow the expression is almost simplified as it is:
2x + 1 -(-2x)
The 2nd stop involves addition. First we have to know what -(-2x) means. Think of the negative sign on the outside as -1. This way it would be:
3) -1(-2x), and then do -1(-2) which is 2 since a negative times a negative is positive.
4) Now we know that -(-2x) is the same as: + 2x.
5) So the expression would be 2x + 1 + 2x. Combine like terms ( 2x and 2x) and you will get 4x + 1.

if 15 sandwiches are sold for 12 Rand what would 12 sandwiches be sold for
Answer:
$9.60 for 12 sandwiches
To solve the problem we will calculate the cost of 1 sandwich first.
The cost of 12 sandwiches is 9.6 Rands.
Given
15 sandwiches are sold for 12 Rand
What is the value of 1 sandwich?We know the cost of 15 sandwiches is 12 Rand, therefore,
[tex]\text{Cost of 1 Sandwich} = \dfrac{\rm 12\ Rand}{\rm 15\ Sandwich}[/tex]
[tex]\text{Cost of 1 Sandwich} = \dfrac{12}{15} = 0.8\ \rm Rand/Sandwich[/tex]
What is the cost of 12 Sandwiches?The cost of 12sandwiches can be calculated using the cost of 1 sandwich,
[tex]\text{Cost of 12 Sandwiches} = \text{Cost of 1 sandwich} \times 12[/tex]
[tex]= 0.8 \times 12 = 9.6\ \rm Rand[/tex]
Hence, the cost of 12 sandwiches is 9.6 Rands.

5x/5=15/5-3y/5 (divide 5 on both sides)
x=3-3/5y
For Y:
-5x on both sides will result in:

Answer:
a) 13%

To calculate what percentage is one number (a) of another (b), you have to divide a by b and then multiply result by 100. In this case number of students with grade A is 4, total number of students is 31, therefore 4/31 * 100 = 12.9%. Rounding it to the nearest percentage will give you 13.

Step by step explanationMom buys a rectangular rug with an area of LaTeX: 7\frac{1}{6}7 1 6 square meters. The length of the rug is LaTeX: 3\frac{1}{3}3 1 3 meters. What is the width of the rug?
Answer:
2 3/20 metres
Step-by-step explanation:
Area of the rug = Length × width
Given
Area = 7 1/6 metres = 43/6 m
Length = 3 1/3 metres = 10/3 m
Required
Width
From the formula
A = LW
W = A/L
Substitute the given values
W = 43/6÷10/3
W = 43/6×3/10
W = 43/2 ×1/10
W = 43/20
W = 2 3/20 m
Hence the width of the rug is 2 3/20 metres
