On Saturday mornings, Charlie volunteers ate the hospital where his mom works. One Saturday, he answers phone calls at the information desk while the receptionist is away. Then, he spends 20 minutes delivering flowers to patients' rooms. In all, Charlie volunteers at the hospital for 60 minutes that day. Which equation can you use to find the amount of time t, that Charlie answers phone calls?

Answers

Answer 1

Answer: t + 20 = 60; 40 minutes are spent answering phone calls.

Step-by-step explanation: We know that 20 minutes are spent out of a 60 minute day of volunteer work. So, with the equation, t + 20 = 60, we can solve to find out that 40 minutes are spent answering phone calls.

A.Radius:12 inches,
Height:5 inches

B.Radius:10 inches
Height:4 inches

C.Radius:6 inches
Height:5 inches

D.Radius:6 inches
Height:10 inches

Answers

Answer:

C

Step-by-step explanation:

Try each one using the formula for the volume of a cylinder, pi * r^2 * h:

A. 3.14 * 12^2 * 5 = about 2261 which does not equal 565

B. 3.14 * 10^2 * 4 = about 1256 which does not equal 565

C. 3.14 * 6^2 * 5 = about 565 which is correct!

D. 3.14 * 6^2 * 10 = about 1130 which does not equal 565

Therefore C is the right answer.

Jordan needs 15.5 grams of potassium chlorate for a science experiment. He was able to get 9.72 grams from his science club, and his mom found that they had 3.4 grams in their home science kit.

How many more grams of potassium chlorate does Jordan need?

Answers

Answer:

Jordan needs 2.38 grams✔

Step-by-step explanation:

First you add 9.72+3.4=13.12 than you have to subtract 15.5-13.12=2.38 that's how I got my answer

The number of more grams of potassium chlorate does Jordan need is 2.38 grams

Calculation of number of more grams:

Since the science club is 9.72 grams and there are 3.5 grams for home science kit

So, the total is

= 9.72+3.4

=13.12

Now

The number of more grams should be

= 15.5 - 13.12

=2.38

Answer: x=−2

Step-by-step explanation: Step 1: Subtract 2x from both sides.

−3x−3−2x=2x+7−2x

−5x−3=7

Step 2: Add 3 to both sides.

−5x−3+3=7+3

−5x=10

Step 3: Divide both sides by -5.

−5x/-5=10/-5

Answer:

[tex] - 3x - 3 = 2x + 7 \\ 2x + 3x = - 7 - 3 \\ 5x = - 10 \\ x = \frac{( - 10)}{5} \\ \boxed{x = - 2}[/tex]

x=-2 is the right answer.
