Alyssa took a math test with 30 questions, and she answered 25 questions correctly in order to get an a, she needs to answer at least 90% of the questions correctly did Alyssa get an a on his math test? Show your work or explain your answer.

No, she did not. She got an 83% which is a B.

Step-by-step explanation:

she got 25 questions right out of 30

that is the same as 25 out of 30

or 25/30

which is the same as 25 points out of the possible 30

so

25 divided by 30

that is the same as 25/30

25/30= 0.83333333

to get the percentage

multiply that number by 100 (it is the same every time)

0.83333 times 100 = 83.333

round, 83

add %

83%

that is less than 90%

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
