Split the figure into three shapes: right triangle no.1, rectangle, and right triangle no.2.

rectangle:
A = l × w
A = 3 × 11
A = 33 cm²

right triangle no.1 (on the left of the rectangle):
find leg 1 first: 17 - 11 = 6
A = ab/2
A = 6 × 3/2
A = 9 cm²

right triangle no.2 (on the right on the rectangle):
A = ab/2
A = 3 × 1/2
A = 1.5 cm²

Add:
33 + 9 + 1.5 = 43.5 cm² (choice b)

(FIRST PERSON TO ANSWER GETS BRAINLIEST!!!) A student earned $2500.75 at his summer job making $12.50 per hour. Let h represent

laiz [17]

Answer:

$12.50 \space\ h = 2500.75$

Step-by-step explanation:

We know from the question that the student earned $12.50 per hour.

Using this information, we can say that if the student worked for h hours, they would make a total of 12.50 × h dollars.

We also know that the total money they earned is $2500.75.

∴ Therefore, we can set up the following equation:

$\boxed {12.50 \times h = 2500.75}$

From here, if we want to, we can find the number of hours worked by simply making h the subject of the equation and evaluating:

h = $\frac{2500.75}{12.50}$

= 200.6 hours

An animal shelter houses dogs, cats, and rabbits. there are 126 animals at the shelter. of the animals, 1/3 are cats. three four

viva [34]

Given that an animal shelter houses three kinds of animals: dogs, cats and rabbits and it has a total of 126 animals. 1/3 of the animals are cats. This means, 1/3 of 126 is 42. So there are 42 cats. 3/4 of the remaining animals, which is 84 are dogs. So 3/4 of 84 is 63. So there are 63 dogs. 63 dogs plus 42 cats is 105 animals. 126 minus 105 is 21. Therefore, there are only 21 rabbits. Hope this helps.
