A store pays $13 for a bicycle helmet and marks up the price by 40% what is the amount of the mark-up?

Answer:

The area of the stage is 75 sq. ft. (ft²)

Step-by-step explanation:

Use " l * w = area"

6.25 * 12 = A

A = 75

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $1,800

Number of periods (t)= 6 months

Monthly interest rate (r)= 0.144/12= 0.012

To calculate the interest to be paid and the total amount due, we need to use the following formula:

I= P*r*t

I= 1,800*6*0.012

I= $129.6

Total amount= $1,929.6

Answer:

-2x^2 + x^2 +11x +2

Step-by-step explanation:

f(x) = 2x^2-5x -3

g(x) = x^2 + 6x -1

h(x) = g(x) - f(x)

x^2 + 6x -1 - 2x^2 +5x +3

-2x^2 + x^2 +11x +2

Step-by-step explanation:

Answer: x>4

Step-by-step explanation:

The solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.

The given inequality is 5x + 6 < 2(-3 - x).

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality can solved as follows:

5x + 6 < 2(-3 - x)

Multiply 2 to the bracket

5x + 6 < -6 - 2x

Add 2x to both the sides of inequality

5x + 6 + 2x < -6 - 2x + 2x

⇒7x+6<-6

Subtract 6 to both the sides of inequality

7x+6-6<-6-6

⇒7x<-12

Divide 7 to both the sides of inequality

7x/7<-12/7

⇒x<-12/7

⇒x<-1.7

Solution set = {-2, -3, -4, -5, -6,.......}

Therefore, the solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.

Try 122.

Step-by-step explanation:

Since x = 1, x^6 = 1.

Since y = 11, 11^2 = 121.

1 + 121 = 122.

Answer:82

Step-by-step explanation:

Answer:

Step-by-step explanation:

We will use a proportion to solve this.

x/y = x/y

let x = the number of families in each case

let y = the number of plants in each case

Since we don't know the second y, we will leave that as y and solve for it.

50/150 = 65/y

Cross-multiply

50y = 9750

Divide

195  = y

Now, we can check this by substituting the value of y back into the equation and seeing if both sides equal.

50 (195) = 9750

9750 = 9750 ✅

Answer:

The first increase was of 60%.

Step-by-step explanation:

The initial value of the product is x.

The first increase was of y.

The second increase is of 25%, that is, 1.25.

The final price was double the original, so 2x.

This situation can be modeled by the following equation:

[tex]xy(1.25) = 2x[/tex]

We want to find y.

Simplifying by x

[tex]1.25y = 2[/tex]

[tex]y = \frac{2}{1.25}[/tex]

[tex]y = 1.6[/tex]

After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

Answer:

B is the better detergent

Step-by-step explanation:

If A has a lower number on the 1-10 scale, that means on average it was closer to the lower end, or the least clean end. This means that A cleans worse than B., and B is better.

The two laundry detergents B cleans better.

Although the questions seems to be tricky at the begging because of a lot of numbers, but actually it is not.

Given to us in the question that, 25 pieces are randomly assigned to be cleaned with detergent A, and the remaining 25 pieces are cleaned with detergent B.

Thus, we can say that the sample size for both detergent A and detergent B is same. Also, the sample is distributed randomly meaning the sample is unbiased (fair).

Also, as given the mean rating for detergent A is found to be significantly less than the mean rating for detergent B. And we know that the mean is the average of a set of given numbers.

Therefore, we can conclude that if detergent A has a lower mean meaning, it has cleaned the clothes with less effectiveness as compared to detergent B.

Hence, Out of the two laundry detergents, B cleans better.
