Last month, Curtis bought a new mountain bike for $250. In a store advertisem*nt, the mountain bike is on sale for $210. What is the percent of the decrease in the value of the mountain bike?

### Answers

**Answer:**

16%

**Step-by-step explanation:**

say the percent decrease = x. Then

x/100 x 250 = 210.

x/2 x 5 = 210

x/2 = 210/5

x/2 = 42

x = 42 x 2

x = 84.....

BUT this is not the answer. We need 100-84=16 for the answer.

So the bike dropped 16%. Thank me later :)

If Curtis bought a new mountain bike for $250. In a store advertisem*nt, the mountain bike is on **sale** for $210. Then 16% of the **decrease** in the **value **of the mountain bike

What is Percentage?

percentage, a relative value indicating **hundredth parts **of any quantity

Given,

Curtis bought a new mountain bike for $250.

the mountain bike is on sale for $210.

We need to find the **percent **of the decrease in the value of the mountain bike.

Let the percent **decrease **be x.

x/100 x 250 = 210.

5x/2= 210

**Divide **both sides by five

x/2 = 210/5

x by two equal to two ten by 5, we get x by two equal to forty two

x/2 = 42

Apply **cross multiplication**

x = 42 x 2

x = 84.

We need 100-84=16.

Hence 16 percent of the **decrease** in the value of the mountain bike

How would you graph the solution to 3x ≤ -15?

Draw an open circle on -5 and shade to the left.

Draw an open circle on -5 and shade to the right.

Draw a closed circle on -5 and shade to the left.

Draw a closed circle on -5 and shade to the right.

### Answers

**Answer: C) Closed circle at -5; shading to the left**

The given inequality [tex]3x \le -15[/tex] solves to [tex]x \le -5[/tex] when we divide both sides by 3. The inequality sign does not change because we didn't divide both sides by a negative number.

The graph has a closed circle at -5 to include this value as part of the solution set. Shading is to the left to indicate values smaller than -5. Overall, the graph says "x can be -5 or smaller". If you wanted to exclude -5, you would say [tex]x < -5[/tex] and use an open circle; but that's not the case here.

The Shredder, Inc. produces two types of paper shredders, home and office. The office model requires 6 hours to assembly and 2 finishing work units for finishing work, the home model requires 4 hours to assemble and 12 finishing work units for finishing. The maximum number of assembly hours available is 96 per day, and the maximum number of finishing hours available is 96 per day.

Let

x = the number of office model shredders produced per day and

y = the number of home model shredders produced per day.

Write the system of inequalities that represents the maximum number of shredders that can be produced in one day.

NOTE: 4 inequalities are expected.

### Answers

Answer:

4y + 6x ≤ 96

12y + 2x ≤ 96

Step-by-step explanation:

Paper shredders produced :

Home :

Assembling time = 4 hours

Finishing work unit = 12

Office :

Assembling time = 6 hours

Finishing work unit = 2

Maximum number of assembly hours = 96 / day

Maximum number of finishing hours = 96/ day

Let

x = the number of office model shredders produced per day and

y = the number of home model shredders produced per day

(office Assembly hours x Number of office model) + (Assembly hours * number home models)

OFFICE MODEL:

Assembly operation :

Home + office ≤ 96

4y + 6x ≤ 96

Finishing operation :

Home + office ≤ 96

12y + 2x ≤ 96

Two-thirds of the fruit in a basket are apples. One-fourth of the apples are green apples. What fraction of the fruit in the basket are green apples?

**Step-by-step explanation:**

PLS GIVE BRAINLIEST

First, we need to find the least common denominator. This would be 12. So, our new fractions would be 8/12 and 3/12. We know that 8/12 of the basket are apples, and we need to take away the 3/12 of the green apples. This means there are 5/12 of the red apples.

In a recent year, grade 8 Washington State public school students taking a mathematics assessment test had a mean score of 281 with a standard deviation of 34.4. Possible test scores could range from 0 to 500. Assume that the scores are normally distributed.

A random sample of 60 students is drawn from this population. What is the probability that the mean test score is greater than 290? Leave answers in decimal form, not percentages. Round to the nearest Hundredth (two decimal places).

### Answers

**Answer:**

The probability that the mean test score is greater than 290

P(X⁻ > 290 ) = 0.0217

**Step-by-step explanation:**

* Step(i):*-

Mean of the Population (μ) = 281

Standard deviation of the Population = 34.4

Let 'X' be a random variable in Normal distribution

Given X = 290

[tex]Z = \frac{x -mean}{\frac{S.D}{\sqrt{n} } } = \frac{290-281}{4.44} = 2.027[/tex]

**Step(ii):-**

** The probability that the mean test score is greater than 290**

P(X⁻ > 290 ) = P( Z > 2.027)

= 0.5 - A ( 2.027)

= 0.5 - 0.4783

= 0.0217

The probability that the mean test score is greater than 290

P(X⁻ > 290 ) = 0.0217

### Answers

**Answer:**

7.64 in.

**Step-by-step explanation:**

The **diameter **of the **circle **whose circumference is 24 inches is 7.654 **inches**.

What is a circle?

A **circle **is a two-dimensional object made up of **points **that are spaced out from a given point (**center**) on the plane by a fixed or constant distance (**radius**).

**Given**:

The circumference of the circle, C = 24 inches,

Calculate the radius of the circle as shown below,

Circumference = [tex]2\pi r[/tex]

C = 2 × π r

r = 24 / 2π

r = 3.819

r = 3.82 inches

Calculate the diameter as shown below,

Diameter = 2 × r

Diameter = 2 × 3.82

Diameter = 7.639 inches

Thus, the diameter is 7.64 inches.
