Jimmy typed a 36-word paragraph in 2/3 minute. What is his typing speed in words per minute?

Jimmy's typing speed is 54 words per minute

Step-by-step explanation:

2/3?/60

2(20)/3(20)

40/60 is 2/3 of a minute

36/40 =9/10

9(6)/10(6) = 54/60

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

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
