What number is 133% of 200

Answers

Rewrite 133% as a decimal by dividing by 100:

133% = 1.33

Now multiply:

200 x 1.33 = 266

Answer: 266

133% of 200 = 266

Explanation:

133 of 200 can be written as:

133/200

To find a percentage, we need to find an equivalent fraction with the denominator 100. Multiply both numerator & denominator by 100

Multiply both numerator & denominator by 100 Therefore, the answer is 66.5%If you are using a calculator, simply enter 133÷200×100 which will give you 66.5 as the answer and as we know 66.5 is also known as 226.

Jeremy can row 2/3 of a mile in 1/2 hour how long will it take him to row 1 mile?

Answers

Answer:

It takes 3/4 of an hour to go 1 mile

Step-by-step explanation:

You can do this by setting up a proportion and by using decimals for some fractions

2/3 = 0.66667 Miles

1/2 = 0.5 hours

0.66667/0.5 = 1/x Cross multiply

0.66667 * x = 0.5 * 1 Simplify

0.66667 * x = 0.5 Divide both sides by 0.66667

x = 0.5 / 0.66667

x = 0.74999625 Notice when rounded this is 0.75

x = 0.75 Now notice that 0.75 as a fraction is 3/4

x = 3/4

Jeremy can row 2/3 of a mile in 1/2 hour then it will take him 3/4 hour to row 1 mile.

If Jeremy can row 2/3 of a mile in 1/2 hour, then the time it takes him to row 1 mile can be found by setting up a proportion:

(2/3 mile) / (1/2 hour) = 1 mile / (x hours)

Cross-multiply:

(2/3) × x = 1 × (1/2)

Now solve for x:

x = (1/2) / (2/3)

x = 3/4

So, it will take Jeremy 3/4 of an hour (or 45 minutes) to row 1 mile.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Maya utilized a drawing to partition 86 she made gatherings of 17 with 1 remaining over.

Then the number of the groups that may make will be given as,

⇒ (86 - 1) / 17

Simplify the expression, then we have

⇒ (86 - 1) / 17

⇒ 85 / 17

⇒ 5

If Lucia lost approximately 100 balls after playing at Rolling Hills rr times and Meandering Meadows mm times, which of the following equation best represents the relationship between rr and mm?

8r+12m=1008r+12m=100

12r+8m=10012r+8m=100

12r-8m=10012r−8m=100

8r-12m=1008r−12m=100

Answers

The relationship between the number of balls Lucia lost at the golf

courses can be expressed as an equation.

The equation that best represents the relationship between r and m is; 12·r + 8·m = 100

Reasons:

The given parameters are;

The number of balls Lucia loses at the Rolling Hills, r = 12 balls

The number of balls Lucia loses at the Meandering Meadows, m = 8 balls

The total number of balls Lucia lost after playin at Rolling Hills and Meandering Meadows = 100 balls

The relationship between r and m is therefore;

Number of balls lost at Rolling Hills + Number of balls lost at Meandering Meadows = 100

12 × r + 8 × m = 100

12·r + 8·m = 100

The equation that best represents the relationship between r and m is therefore; 12·r + 8·m = 100
