Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Answers

Answer:30M + 1500 less than or equal to 4500

this should be the right awnser

Step-by-step explanation:

Answer:

100 minutes (or 1 hour and 40 minutes)

Step-by-step explanation:

to start I subtracted 4,500( how much it can hold) by 1,500 (how much it has already) to get 3,000.  

4500 - 1500 = 3000 (300 + 1500 = 4500)

so the pool would need 3,000 more gallons of water to reach the limit,

then divide 3,000 by 30 to know how many 30 gallows would be needed to reach the limit

3,000 ÷ 30 = 100 (100 x 30 = 3,00 so this is correct)


He would need to add water for 100m to avoid exceeding the limit.

That is as far as I know, you can utilize this problem to write an appropriate Inequality, I hope this is helpful!

Step-by-step explanation:

U 2 can help me by marking as brainliest.....

Remember whole numbers are shown as 15 or 15/1. So the first step is to see it as this. 15/1 divided by 1/9.

Next you have to flip the 1/9 to its reciprocal which is 9/1 AND change the division to multiplication.

So now you have 15/1 x 9/1. This equals 135/1

Hans is saving money to buy a game. So far he has saved $24, which is three-fourths of the total cost of the game. How much does the game cost?

Answers

Answer: The game costs $ 32 if $24 is three-fourths of total cost of the game. It is solved by making a mathematical equation containing fractions.

Step-by-step explanation:

Let's assume total cost of the game is $Y,

We know that three-fourths of Y is $24.

so we get the following mathematical equation

3/4 x Y= 24

Multiplying with 4/3 on both sides of the equation,we get

(4/3) x (3/4) x Y= 24 x (4/3)

since (4/3 x 3/4 =1), we get the equation

Y=24 x (4/3) =96/3 =32

Therefore, the cost of the game is $32

Answer: The total cost of the game is $32.

Step-by-step explanation:

Let's assume the total cost of the game is represented by the variable "x".

Given information says that, Hans has saved $24, which is three-fourths (3/4) of the total cost of the game. We can set up the following equation:

3/4 * x = $24

To find the value of "x," we can solve this equation:

3/4 * x = $24

To isolate "x," we can multiply both sides of the equation by the reciprocal of 3/4, which is 4/3:

x = ($24) * (4/3)

x = $32

Therefore, the total cost  is $32.

Step-by-step explanation:

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3800 and his stock in Company B was worth $3400. The stock in Company A has decreased 22% since last year and the stock in Company B has decreased 12%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answers

Answer: The total percentage decrease in the investor's stock account is 34%

Step-by-step explanation:

The investor's stock in Company A= $3800

The investor's stock in Company B= $3400

Percentage decline in stock of company A= 22%

Decline in value of stock of company A= 3800× 22/100

= 38×22

= $836

Percentage decline in stock of company B= 3400×12/100

= 34×12

=$408

Total decline in wealth of investor= 836+ 408

= $1244

Total percentage decline in wealth= 1244×100/7200

= 124400/7200

= 17.27%

The percentage decrease in investor's stock is 17.27%

A container has a cylinder shape has volume of 125.6 cm cubed the hight is 10 cm what is the radius . Also use 3.14 for pi

Answers

The formula for the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius, h is the height, and π is pi.

Substituting the given values, we have:

125.6 = 3.14 x r^2 x 10

Dividing both sides by 3.14 x 10, we get:

r^2 = 4

Taking the square root of both sides, we get:

r = 2 cm

Therefore, the radius of the cylinder is 2 cm.
