The ratio of dogs to cats at the pet store is 1:2. There are 15 dogs. How many cats are there?

Answers

30 cats because 15 times 2 is 30 and 15 times 1 is 15
Final answer:

To find the number of cats at the pet store, set up a proportion using the given ratio of dogs to cats and the number of dogs. Cross multiply to solve for the number of cats.

Explanation:

To find the number of cats at the pet store, we need to use the given ratio of dogs to cats. Since the ratio is 1:2 and there are 15 dogs, we can set up a proportion to solve for the number of cats. We can write the proportion as 1/2 = 15/x, where x represents the number of cats. We can cross multiply to find x, which gives us x = 30. Therefore, there are 30 cats at the pet store.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The time taken by both Robin and Brandy will be calculated as follows:-

Total Efficiency = ( 1 / 4 + 1 / 3 )

                         = ( 4 + 3 ) / 12

would a field with a width 75 yards and an area of 7500 square yards be within FIFA regulation?why or why not.

Answers

Final answer:

Yes, a field with a width of 75 yards and an area of 7500 square yards would be within FIFA regulation.

Explanation:

The area of a rectangle is calculated by multiplying its length by its width. In this case, the width of the field is 75 yards and the area is 7500 square yards. To determine if the field is within FIFA regulation, we need to compare its area to the typical dimensions of a soccer field.

A typical soccer field has a length of 100-130 yards and a width of 50-100 yards. Since the field in question has a width of 75 yards, it falls within the acceptable range. Therefore, the field with a width of 75 yards and an area of 7500 square yards would be within FIFA regulation.

3/5 pt of juice is poured into 6 glasses.How much juice is in each glass?

Answers

Each glass contains 1/10 pt of juice when 3/5 pt of juice is evenly divided into 6 glasses.

To determine how much juice is in each glass when 3/5 pt of juice is poured evenly into 6 glasses, one must divide the total amount of juice by the number of glasses. This is a basic division problem often encountered in converting customary units in real-world situations.

First, convert the pint (pt) measurement to a more convenient unit if needed. In this case, we can keep it in pints since the division is straightforward. Next, divide the 3/5 pt of juice by 6.

Calculate the amount of juice in each glass: 3/5 ÷ 6 = 3/5 × 1/6 = 3/30 = 1/10.

Convert the fraction to pint measurement if necessary: 1/10 pt.

So each glass would contain 1/10 pt of juice.

What is 4/7 of 49

Please explain why

Answers

4/7 of 49 = 28, the reason why is because if you divide 49 into 7 different groups, you will get 7 groups of 7(7x7=49). And if you take 4 of those groups, the answer is 28(7x4=28)
28 because if you divide 49 by 7 you would get 7 and then multiply it by 4. Then you get the answer of 28.

A clockwise rotation of 90 degrees is equivalent to a counter clockwise rotation of how many degrees?

Answers

Equivalent to 180 degrees. 90 degrees clockwise +90 degrees

The counter-clockwise rotation of the clockwise 90-degree rotation will be  180 degrees.

What is clockwise rotation?

Clockwise motion, also known as CW, moves from top to bottom, then down and left, and then back to top in the same manner as a clock's hands. The opposing direction of rotation or revolution is anticlockwise (ACW) or counterclockwise (CCW).

Given that there is a rotation of 90 degrees clockwise. The counterclockwise rotation will be calculated as.

The counterclockwise rotation will be equal to 180 degrees because the rotation will be first of 90 degrees and again of 90 degrees, Mathematically written as,

Counterclockwise rotation = 90 + 90

Counterclockwise rotation = 180

Therefore, the counter-clockwise rotation of the clockwise 90-degree rotation will be  180 degrees.

20(−1.5r+0.75) expand the expression and combine like terms

Answers

20(−1.5r + 0.75)

here, you need to distribute the "20" to the inside of your parentheses. you'll be multiplying 20 and -1.5 first:

-30r

then 20*0.75 second:

-30r + 15 is your expanded expression. you can't combine like terms any further.

Answer:

-30r + 15

Step-by-step explanation:

We have been given that

20(−1.5r+0.75)

Use the distributive property a(b+c)=ab+ac.

20×(−1.5r)+20×0.75

Multiplying, we get

-30r +15

These two are not like terms. Hence , we cannot combine them.

Therefore, we cannot simplify it more.

Hence, the simplified expression is -30r + 15

17. 1/6 years.

18. 1/4 years.

19. 1/3 years.

20. 1/2 years.

What is a percentage?

In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100).

Part 14.

Mathematically, percentage increase can be calculated by using the following mathematical equation:

Percentage increase = (Final value - Initial value)/Initial value × 100

Percentage increase = (45 - 35)/35 × 100

Percentage increase = 10/35 × 100

Percentage increase = 28.57 ≈ 29%.

Part 15.

Mathematically, percentage decrease can be calculated by using the following mathematical equation:

Percentage decrease = (Final value - Initial value)/Final value × 100

Percentage decrease = (60 - 38)/60 × 100

Percentage decrease = 22/60 × 100

Percentage decrease = 36.67 ≈ 37%.

Note; 1 year is equal to 12 months.

In order to express each number of months in years, we would divide the number of month by 12;

Part 17.

Time = 2/12

Time = 1/6 years.

Part 18.

Time = 3/12

Time = 1/4 years.

Part 19.

Time = 4/12

Time = 1/3 years.

Part 20.

Time = 6/12

Time = 1/2 years.
