10 pounds of flour cost $8. How much does 40 pounds of flour cost? What is the cost per pound of flour?

Step-by-step explanation:

10<=x<=20

10 less than or equal to x , less than or equal to 20

Answer: $14

Step-by-step explanation: You have to multiply 20 by .3 (30%) which is 6. Now you subtract 6 from 20 and get 14.

Answer:

It takes him 1 minute and 25 seconds

Step-by-step explanation:

5 ÷ 4 = 1.25

The number of laps per minute is 1.25 laps.

Given that, time = 4 minutes and the number of laps = 5.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here,

Number of laps per minute = Total number of laps/Number of minutes

= 5/4

= 1.25 laps

Therefore, the number of laps per minute is 1.25 laps.

Answer:

15/13

Step-by-step explanation:

Convert to improper fractions: 5/2 divided by 13/6

Multiply the first term by reciprocal: 5/2 * 6/13 = 30/26

Simplify: 30/26 can become 15/13

[tex] = 2 \frac{1}{2} \div 2 \frac{1}{6} [/tex]

[tex] = \frac{5}{2} \div \frac{13}{6} [/tex]

[tex] = \frac{5}{2} \times \frac{6}{13} [/tex]

[tex] = \frac{30}{26} [/tex]

[tex] = \frac{30 \div 2}{26 \div 2} [/tex]

[tex] = \frac{15}{13} [/tex]

[tex]\color{hotpink} = 1 \frac{2}{13} [/tex]

[tex]\therefore\color{olive}2 \frac{1}{2} \div 2 \frac{1}{6} = \color{hotpink} \frac{15}{13}\color{olive} (or) \color{hotpink}1\frac{2}{3} [/tex]

Answer:

x=7

Step-by-step explanation:

4 (3x+4)= 100 ft (Perimeter = sum of all 4 sides)

12x + 16 =100 ft (Multiply length of one side by 4, which is number of side on a square)

12x = 84 (This is what is left after subtracting 16 form both sides of the equation making the equation still true)

x = 7 (84 divided by 7 to let X stand alone and get the value of x)

Answer:

The boxes are classified as underweight or not. X, the number of underweight boxes will be approximately ___normally___distributed

Step-by-step explanation:

For a normal distribution the sample size must be less than or equal to 30.

The central limit theorem states that if a variable X from a population has a mean u and a finite variance σ² then the sampling distribution of the sample mean x bar approaches  a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.

In the given question the sample size n= 10 and population size N= 3000.

Here n < 30 . But if the population is normal this theorem holds true for sample size n < 30.

The number of underweight boxes should be normally distributed.

It is the distribution where the sample size should be lower than or equal to 30

Since the size of the sample is n = 10 and the size of the population is N = 3000

So here n should be less than 30

Therefore, it is normally distribution.

Answer: C=-3t+30

Step-by-step explanation:

The equation of remaining chocolate C  in terms of t could be C =30 - 3t.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given that the Initial number of chocolates in box = 30

Also after 8 nights, number of remaining chocolates = 6

Then we have

In 8 nights, 24 chocolates were treated.

In 1 night, 3 chocolates were treated.

The equation of remaining chocolate C  in terms of t can be written by;

C =30 - 3t.
