the length of the swimming pool is 8 m longer than its width and the area is 105 m squared write in quadratic equation ​

Answers

Answer 1

Answer:

Step-by-step explanation:

The length of the swimming pool is 8m longer than it's width.

If we say L = length, W = width

From the information above, we can say

L= 8 + w

We are also told the area is 105 m squared.

Note:

Area of a Rectangle = Length x Width

105 =  (8 + w ) x w

[tex]105 = 8w + w^2\\[/tex]

Subtract 105 from both sides:

[tex]w^2 + 8w - 105 = 0[/tex]

At a local pizza shop, large pizzas cost $14.50 and small pizzas cost $9.00. On Thursday, the number of large pizzas sold was 3 less than twice the number of small pizzas sold. The total value of all pizzas sold was $640.50. How many of each type of pizza did the pizza shop sell?

Answers

Answer:

Small pizzas = 21

Large pizzas = 39

Step-by-step explanation:

The number of small pizzas sold be x

So, the number of large pizzas sold be 2x - 3

And the total value is $640.504

Now the equation would be

$14.50x + $9 × (2x - 3) = $640.50

$14.50x + 18x - $27 = $640.50

$32.50 = $640.50 + $27

$32.50x = $667.50

x = 21

Now the large pizzas is

= 2 × 21 - 3

= 39

10 Brynlee's monthly cell phone bill
is $60 a month plus $2.50 per
gigabyte used. Raylin's cell phone bill is $450
per month plus $3.25 per gigabyte used.
Determine after how many gigabytes used
would the cell phone plans cost the same
for the month what is the answer??

Answers

Answer:

20 gigabytes

Step-by-step explanation:

Let n represent the amount of gigabytes used.

First make an equation for each senario, Brynlee's would be 60+2.50n and Raylin's would be 45+3.25n.

Set them to equal each other, 60+2.50n=45+3.25n.

Then isolate for n.

60-45=3.25n-2.50n

15=0.75n

Divide both sides by 0.75 to get 20

Jane and her friends are going on a hiking trip. Jane wants to make snack packs to take on a trip. She has 24 apples and 36 small bags of trail mix. Each snack pack must have the same number of apples and the same number of bags of trail mix. What is the greatest number of snack packs Jane can make? Explain.

Answers

Answer:

The greatest number of snack packs Jane can make is 12 snack packs

Step-by-step explanation:

We solve this question using the greatest common factor method

First step would be to find the factors of 24 and 36

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

Then the greatest common factor amongst the above factors for 24 and 36 is 12.

Therefore, the greatest number of snack packs that she can make is 12 packs.

A three-digit personal identification number is chosen using the digits 1–9. The digits cannot be repeated. What is the approximate probability that the first digit will be 6? 0.00595 0.03571 0.11111 0.66667

Answers

Answer: C

Step-by-step explanation:it’s the 3rd ans on edge

The question is an illustration of probability, and the approximate probability that the first digit will be 6 is (c) 0.11111

How to determine the probability?

The number of digits in the pin = 3

Given that each digit cannot be repeated, the total number of pin is:

Pin = 9 * 8 * 7

Evaluate

Pin = 504

If the first digit is 6, the number of pins is:

First digit6 = 1 * 8 * 7

First digit6 = 56

So, the probability that the first digit is 6 is:

P = 56/504

Evaluate

P = 0.1111

Hence, the approximate probability that the first digit will be 6 is (c) 0.11111

A magic carpet is made with three colors of yarn. The ratio of each color in the carpet is shown below: 10 parts gold yarn 7 parts bronze yarn 3 parts silver yarn The magic carpet is made with a total of 150 meters of yarn. How much silver yarn is in the magic carpet?

Answers

Answer:

There are 22.5 meters of silver yarn

Step-by-step explanation:

Gold yarn : bronze yarn : silver yarn

10 : 7 : 3

Gold yarn = 10

bronze yarn = 7

silver yarn = 3

Total ratio = 20

Total meters = 150 meters

How much silver yarn is in the magic carpet?

Quantity of silver yarn in the carpet = silver yarn ratio / Total ratio × total meters of yarn

= 3 / 20 × 150

= 450 / 20

= 22.5 meters

There are 22.5 meters of silver yarn

Bronze yarn = bronze yarn ratio / Total ratio × total meters of yarn

= 7 / 20 × 150

= 1,050 / 20

= 52.5 meters

Bronze yarn = 52.5 meters

Quantity of gold yarn in the carpet = gold yarn ratio / Total ratio × total meters of yarn

= 10 / 20 × 150

= 1500 / 20

= 75 meters

Gold yarn = 75 meters
