an aquarium has a ratio of 5 rays for every 3 sharks. What percent of this grouping of animals are rays

sashaice [31]

Answer:

62.5%

Step-by-step explanation:

Total number of animals in a group= 5+3=8 animals

Number of rays=5

Since we only have 5 rays out of the total 8, to express the number of rays as a percentage of the total animals, we divide the number of rays by the total animals then multiply by 100 to express in percentage as needed in the question

Percentage of rays= $\frac {5}{8}\times 100=62.5$

Therefore, the percentage is 62.5%

Find the slope of the line 8x – 4y = 8\ (hint: find 2 points; then use the slope formula)

Vera_Pavlovna [14]

8x - 4y = 8

-4y = -8x + 8

y = -8x/-4 + 8/-4

y = 2x - 2, comparing to y = mx + c, slope m = 2

Slope = 2.
