What do you call two ratios that have the same value

Answers

The ratios are called equivalent ratios, which have the same values.

What are ratios?

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given to name the  two ratios that have the same value,

The ratios are called   equivalent fractions,

Comparable to equivalent fractions are equivalent ratios. An equivalent ratio results from multiplying or dividing the antecedent (the first term) and the consequent (the second term) of a given ratio by a non-zero value.

for example, 1/3 is also written as  2/6, 3/9, and so on,

and each of them has a value equal to 1/3.

Hence the ratios are equivalent fractions.

You put $500 in your bank account. With an interest rate of 5%, how long will it take the account to reach $600? Use the formula: I = Prt.

Answers

Hence, It will take 4 years.

What is interest?

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

Here, we have,

formula: I = Prt.

i.e. t = I/Pr

we have,

Note the 600 is the total amount in the account.

Therefore Interest, I = 600 - 500 = 100.

t = 100 / (500 * 5%)

t =  100 / (500 *0.05)

t = 4

Hence, It will take 4 years to reach $600.

Like earlier take the bigger shape and divide the smaller one.
8.4 divide by 4 and you get 2.1.
a) Scale factor is = Second Value / First Value
                           =    8.4 / 4 = 2.1

b)  0.25 =  Second Value / First value

0.25 =  Second Value / 9

Second value = 0.25 * 9 = 2.25.

How do you find the surface area of a circle?

Answers

Answer:

πr²

Step-by-step explanation:

The surface area of a circle is πr²

Pie is 22/7 or 3.14

While the radius of a circle is any line from the centre of a circle to any part of the circumference of the circle. A diameter is any line that cuts the circle into two equal halves, cutting the circle from the centre.

To get the surface area of a circle, you draw a line from the centre of the circle, and then touch any part of the circumference of the circle. Then you measure the line, that's the radius.

If for instance, the radius gives 7cm, you find the Square, And then multiply it with pie.

22/7 X 7 ²

22/7 X 7 X 7

22 X 7

154cm²
