Answer:

m = 24

Step-by-step explanation:

m + 7° + 2m + 11° = 90°

3m + 18° = 90°

3m = 90°- 18°

3m = 72

(divide both sides by 3)

therefore : m = 24

90-11=79
79=2m+m+7
79=3m+7
79-7=3m
72=3m
72/3=3m/3

24=m

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%

OlgaM077 [116]

Answer:

Students collected

$85+255=340$ pounds of paper;
$18+90=108$ pounds of cans;
$340+108=448$ pounds of paper and cans combined in September and October.

Step-by-step explanation:

In September, the students collected 85 pounds of paper and 18 pounds of cans to recycle.

In October, their goal is to collect three times the amount of paper and five times the amount of cans they collected in September.

Hence, in October they collected

$85\times 3=255$ pounds of paper;
$18\times 5=90$ pounds of cans.

In total, they collected

$85+255=340$ pounds of paper;
$18+90=108$ pounds of cans;
$340+108=448$ pounds of paper and cans combined in September and October.
