Write a situation for 15x - 20 ≤ 130 and solve

Answers

Final answer:

To write a situation for the inequality 15x - 20 ≤ 130 and solve it, let's assume that x represents the number of hours a student can study. The solution to the inequality is x ≤ 10, meaning the student needs to study for 10 hours or less to complete the required amount of work.

Explanation:

To write a situation for the inequality 15x - 20 ≤ 130, let's assume that x represents the number of hours a student can study. In this situation, the left-hand side of the inequality represents the amount of work the student has already completed (15x - 20) and the right-hand side represents the total amount of work the student needs to complete (130). The inequality states that the amount of work completed should be less than or equal to the total amount of work required. To solve the inequality, we can follow these steps:

Add 20 to both sides of the inequality: 15x - 20 + 20 ≤ 130 + 20, which simplifies to 15x ≤ 150.Divide both sides by 15 to isolate the variable x: 15x/15 ≤ 150/15, which simplifies to x ≤ 10.

Therefore, the solution to the inequality is x ≤ 10. This means that the student needs to study for 10 hours or less in order to complete the required amount of work.

Amy is in a craft store looking at packages of Pom-poms. Amy sees packages of four red pom-poms. Amy says she can buy seven packages of four pom-poms or four packages of seven pom-poms because she will get the same total of pom-poms. Is Amy correct? Show all mathematical thinking.

Answers

First, let's calculate the number of pom poms she get if she buys 7 packages of 4.
Multiply each number to get the value.
7 x 4 = 28
Shell get 28 pom poms.

Now let's calculate the number of pom pom if she gets 4 packages of 7.
4 x 7 = 28
She gets 28 pom poms.

Therefore, both of these options gets the same amount of pom poms, which is 28, therefore Amy is correct.
Final answer:

Amy is incorrect because both options will give her the same total number of pom-poms.

Explanation:

Amy is incorrect in her statement. Let's calculate the total number of pom-poms in each scenario. If she buys 7 packages of 4 pom-poms, she would have 7 * 4 = 28 pom-poms. On the other hand, if she buys 4 packages of 7 pom-poms, she would have 4 * 7 = 28 pom-poms as well. So, both options result in the same total number of pom-poms.

the original cost of a lamp is $18.95 . The lamp is on sale for 75% off . How much will you pay ?

Answers

18.95x0.75=14.2125

18.95-14.2125=4.73

You will pay $4.73

Answer:

$4.74

Step-by-step explanation:

We have been given that the original cost of a lamp is $18.95 . The lamp is on sale for 75% off.

The cost of lamp after sale would be 25% (100-75) of $18.95.

[tex]\text{The cost of lamp after sale}=\$18.95\times \frac{25}{100}[/tex]

[tex]\text{The cost of lamp after sale}=\$18.95\times 0.25[/tex]

[tex]\text{The cost of lamp after sale}=\$4.7375[/tex]

[tex]\text{The cost of lamp after sale}\approx \$4.74[/tex]

Therefore, you will have to pay $4.74 for the lamp.

factor the polynomial completely y^3+6y^2-4y-24

Answers

 y3-6y2-4y+24 Final result : (y + 2) • (y - 2) • (y - 6)

You might try factoring by grouping first.

Note that y^3+6y^2 = y^2(y+6), and that -4y-24 = -4(y+6).  So, (y+6) is a factor common to the first group of 2 terms and the 2nd grp of 2 terms.

We get  (y+6)[y^2 - 4].  Note that y^2-4 is easily factorable:  (y-2)(y+2),
so we now have three factors of the original poly:

what is the price of a remote control helicopter is $34.40. A remote control boat cost 4/5 the price of the helicopter. Sales tax on the remote control boat is 8%. What is the price of the remote control boat, including sales tax? Round your answer to the nearest penny

Answers

The answer rounded would be 29.94
First, let’s multiply 34.4 to get 1% of that price.
34.4 x 0.01 = 0.344
Then, let’s multiply that 1% by 80 to get the price of the remote controlled boat, since it’s 4/5 the price of the helicopter.
0.344 x 80 = 27.52
$27.52 is the regular price of the boat.
Now, let’s find the 8% of that price. We’ll first first 1% and then multiply our answer by 8 to get 8%.
27.52 x 0.01 = 0.2752
0.2752 x 8 = 2.2016
Sales tax will be $2.20
The total will add the sales tax to the regular total of the boat.
$27.52 + $2.20 = $29.72
$29.72 is your answer.
