what is the length of x

Answers

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar, then the ratios of corresponding sides are equal, that is

[tex]\frac{9}{3}[/tex] = [tex]\frac{x}{5}[/tex] ( cross- multiply )

3x = 45 ( divide both sides by 3 )

x = 15

Convert the following repeating decimal to a fraction in simplest form.
.78

Answers

Answer:

78/100

Step-by-step explanation:

Since .78 is in the hundredths place just move the decimal two places to the right then put it over 100. But idk if you mistyped this because .78 is not a repeating decimal

Answer:

6/9

Step-by-step explanation:

Change 0.7878 to a fraction.

Let n = 0.7878... Multiply both sides by 100 (by 100 when there are two repeating decimal digits)

100n = 78.7878... Subtract n from 100n.

99n = 78 Divide both sides by 99

n = 78/99 but n is 0.7878..., so

0.7878... = 78/99

Similarly with 0.66...

Let n = 0.66... Multiply both sides by 10 (by 10 when there is only one repeating digit)

10n = 6.66... Subtract n from 10n.

9n = 6 Divide both sides by 9.

n = 6/9 but n is 0.66..., so

0.66... = 6/9

Roberta bought 9/10 to pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5-pound bags can Roberta fill? Does she have any left over?

Answers

Answer:

Step-by-step explanation:

The number of the 2/5-pound bags can Roberta fill will be 2.25.

What is an expression?

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Roberta bought 9/10 pounds of raisins. She put 2/5 pounds in bags for her lunch.

The number of bags will be calculated as below:-

Number = ( 9 / 10 ) / ( 2 / 5 )

Number = 2.25

Therefore, the number of the 2/5-pound bags can Roberta fill will be 2.25.

in order to find this out you would first divide the original price of 39.99 by 100 in order to find out what 1% is. Then you would multiply this number by 25 to find out what 25% is. Then you would subtract the original amount of 39.99 by the 25% amount in order to find out how much is taken off
