harmaine spent a total of $20 at the grocery store. Of this amount, $9 she spent on fruit. What percentage of the total did she
zheka24 [161]

Answer:

45%

Step-by-step explanation:

First, let's set up a fraction of how much money she spent for fruit out of the total amount of money she spent.

\frac{9}{20}

For a percentage, we need a fraction out of 100. To do this, we can multiply  the fraction by 5/5 (5*20=100). Notice we can only do this since 5/5 is equivalent to 1, so you are technically multiplying the fraction by 1.

\frac{9}{20}*\frac{5}{5}=\frac{45}{100}

A percentage is just the numerator of a number over 100 therefore it is equal to...

45%

Can the sides of a triangle have lengths 1, 7, and 11? Explain
Airida [17]

No

Given 3 sides of a triangle, the sum of any 2 sides must be greater than the third side.

Consider the 3 given sides 1, 7 and 11

7 + 11 = 18 > 1

1 + 11 = 12 > 7

1 + 7 < 11 ⇒ not valid

Hence these sides do not form a triangle

Tamiku [17]

Answer:

Therefore first number is 3 and second number is 18

Step-by-step explanation:

Sum of the two numbers is 21 and Second number is six times the first number

x+6x = 21

 7x = 21

x = 21/7

x = 3

substitute x value in 6x to find second number,

 = 6x

 = 6*3

 = 18
