Answer:
6
Step-by-step explanation:
6 is the answer because 6 times 8 equals 48, so if you divide 48 by 8 then the quotient would equal 6.
The number 48 should be divided by 6 to equal eight is 48 ÷ 6 = 8
To find what number 48 should be divided by to equal eight, we can set up the division equation and solve for the unknown value.
Let's represent the unknown number by 'x':
48 ÷ x = 8
Now, to find the value of 'x,' we can isolate it by performing the inverse operation of division, which is multiplication. We can multiply both sides of the equation by 'x':
x * (48 ÷ x) = x * 8
On the left side, 'x' cancels out with the 'x' in the denominator, leaving us with:
48 = 8x
Next, we can solve for 'x' by dividing both sides by 8:
48 ÷ 8 = 8x ÷ 8
6 = x
Therefore, the number 48 should be divided by 6 to equal eight:
48 ÷ 6 = 8

The area A of the rectangle shown
is described with the inequality
60 A 140. Write and solve a
compound inequality for x.
Step-by-step explanation:
Simplifying
4x + -5 = 20x
Reorder the terms:
-5 + 4x = 20x
Solving
-5 + 4x = 20x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20x' to each side of the equation.
-5 + 4x + -20x = 20x + -20x
Combine like terms: 4x + -20x = -16x
-5 + -16x = 20x + -20x
Combine like terms: 20x + -20x = 0
-5 + -16x = 0
Add '5' to each side of the equation.
-5 + 5 + -16x = 0 + 5
Combine like terms: -5 + 5 = 0
0 + -16x = 0 + 5
-16x = 0 + 5
Combine like terms: 0 + 5 = 5
-16x = 5
Divide each side by '-16'.
x = -0.3125
Simplifying
x = -0.3125

Cleo and jandi are having a Halloween party. They have 3 1/2 pounds of candy to divide into 14 goodie bags. How much candy will be in each bag?
Answer:
1/4 pound(s) of candy in each bag
Step-by-step explanation:
3 1/2 (pounds of candy) ÷ 14 (goodie bags) = ?
To make this easier let's turn 3 1/2 into a improper fraction and flip 14/1 (14/1 to 1/14):
3 1/2 = 7/2 14/1 = 1/14
Now we multiply:
7/2 x 1/14 = 7/28 = 1/4
(When you divide fractions, you can flip the second fraction and multiply and get your answer. Remember to simplify once you get your answer!)
Hope I helped! Sorry if wrong!

A test tube is cylindrical in shape with a length of 152 mm and a radius of 6.5 mm. What is the volume of the test tube? Report your answer in mm3 but do not include the unit mm3 in your answer box. Round your answer to the nearest whole number and do not include commas in your answer. The formula for volume of a cylinder is V=πr2h.
Answer:
20165
Step-by-step explanation:
Given:
Length/height (h) of cylindrical test tube = 152 mm
Radius of cylindrical test tube = 6.5 mm
Volume = [tex] \pi r^2h [/tex]
Required:
Volume of cylinder to nearest whole number
Solution:
The volume is given as [tex] V = \pi r^2h [/tex]
Take π as 3.14 and plug the values of r and h into the volume formula.
[tex] V = 3.14*6.5^2*152 [/tex]
[tex] V = 3.14*6.5*152 = 20165.08 [/tex]
Volume of the test tube = 20165 mm³ (nearest whole number)

If 12 cats can catch 6 rats in 2 hours, how many hours would it take 50 cats to catch 75 rats?
Answer:
50 cats would take 6 hours to catch 75 rats.
Step-by-step explanation:
After reading the statement we noticed the existence of two relationships:
1) The amount of cats is directly proportional to the quantity of caught rats.
2) The amount of cats is inversely proportional to time taken to catch rats.
That is to say:
[tex]n \propto \frac{x}{y}[/tex]
[tex]n = k\cdot \frac{x}{y}[/tex] (Eq. 1)
Where:
[tex]n[/tex] - Amount of cats, dimensionless.
[tex]x[/tex] - Amount of caught rats, dimensionless.
[tex]y[/tex] - Time, measured in hours.
[tex]k[/tex] - Proportionality ratio, measured in hours.
Then, we obtain the following relationship by eliminating the proportionality ratio in (Eq. 1):
[tex]\frac{n_{1}\cdot y_{1}}{x_{1}} = \frac{n_{2}\cdot y_{2}}{x_{2}}[/tex] (Eq. 2)
Where:
[tex]n_{1}[/tex], [tex]n_{2}[/tex] - Initial and final amounts of cats, dimensionless.
[tex]x_{1}[/tex], [tex]x_{2}[/tex] - Initial and final amounts of caught rats, dimensionless.
[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final times, measured in hours.
Now we clear final time in (Eq. 2):
[tex]y_{2} = y_{1}\cdot \left(\frac{n_{1}}{n_{2}} \right)\cdot \left(\frac{x_{2}}{x_{1}} \right)[/tex]
By knowing that [tex]y_{1} = 2\,h[/tex], [tex]n_{1} = 12[/tex], [tex]x_{1} = 6[/tex], [tex]n_{2} = 50[/tex], [tex]x_{2} = 75[/tex], then we get that time taken by 50 cats to catch 75 rats is:
[tex]y_{2} = (2\,h)\cdot \left(\frac{12}{50} \right)\cdot \left(\frac{75}{6}\right)[/tex]
[tex]y_{2} = 6\,h[/tex]
50 cats would take 6 hours to catch 75 rats.

Answer:
Simplify the expression.
7x2+14x−3
Step-by-step explanation:
The required simplification can be given as 7x²+ 14x - 3
What is simplification?
The operation in mathematics to process and interpret the relation to make function simple or more simple is called simplify and the phenomenon is called simplification.
We have,
= (5x² + 8x - 3) + (2x² - 7x + 13x)
= 5x²+ 2x²+ 8x - 7x + 13x - 3
= 7x²+ 14x - 3
