Answer:

4. 11/6, 121/36

5. 5/8, 25/64

6. 4/7, 16/49

7. 14/9, 196/81

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of corresponding legs:

perimeter ratio = red leg/blue leg

The area ratio is the square of that:

area ratio = (perimeter ratio)²

perimeter ratio = 11/6

area ratio = (11/6)² = 121/36

perimeter ratio = 5/8

area ratio = (5/8)² = 25/64

perimeter ratio = 4/7

area ratio = (4/7)² = 16/49

perimeter ratio = 14/9

area ratio = (14/9)² = 196/81

Sam takes x minutes yo walk from home to library and 5 minutes more to walk from the library to school than fron home to the lib

LuckyWell [14K]

Answer:

$2x+5\ minutes$

Step-by-step explanation:

Given:

Sam takes x minutes yo walk from home to library.

And takes 5 minutes more to walk from the library to school than from home to the library.

Express the total time taken for Sam to walk from home to school via the library in terms of x.

<u>Solution:</u>

Time taken by Sam to walk from home to library = $x\ minutes$

Time taken by Sam to walk from library to school = $x+5\ minutes$

Total time taken by Sam to walk from home to school via the library = Time taken to walk from home to library + Time taken to walk from library to school

Total time taken = $x+x+5=2x+5$

Therefore, the total time taken for Sam to walk from home to school via the library is $2x+5\ minutes$

An equation was used to predict possible sales of phones for 6 months. The actual sales of phones are also listed.Actual sales 5

Vikki [24]

Answer:

Step-by-step explanation:

To calculate the sum of the residuals, subtract the predicted sales from the actual sales in the table below.

Actual sales 55 150 325 510 780 990

Predicted sales 40 150 300 500 800 1,000

This will show the change between them. Add each residual to find the sum.

55 - 40 = 15

150 - 150 = 0

325 - 300 = 25

510 - 500 = 10

780 - 800 = -20

990 - 1000 = -10

These add up to be 15 + 25+ 10 +-20 +-10 = 20
