$\bf 2log(x-3)+1=5\iff 2log_{10}(x-3)+1=5\\\\\\ 2log_{10}(x-3)=4

5. Ms. Lee has 220 students in all her classes. If her classes collected 2860 pounds of food, how many meals did each student pr

jarptica [38.1K]

Answer:

Each students provides 13 pounds of meal

Step-by-step explanation:

Total students in Ms. Lee class = 220

Total pounds of food collected = 2,860

how many meals did each student provide?

Meals provided by each student = Total pounds of food collected / total number of students

= 2,860 / 220

= 13 pounds

Each students provides 13 pounds of meal

Note: 1.2 pounds of food equals one meal

1.2 pounds : 1 meal = 13 pounds : x meals

1.2/1 = 13/x

1.2 * x = 1 * 13

1.2x = 13

x = 13 / 1.2

= 10.83 meals

Approximately 11 meals to the nearest number

Note:1 kilogram is 2.2 pounds

1 kg : 2.2 pounds = x kg : 13 pounds

1/2.2 = x / 13

1 * 13 = 2.2 * x

13 = 2.2x

x = 13/2.2

= 5.91 kilogram

Approximately x = 6 kilograms

Answer:

Step-by-step explanation:

The only point that is on the line is (3, 6).

I find a graphing calculator to be a useful tool.

For solving this "by hand," you put the x- and y-values into the equation and check to see if it is true.

A. 2(0) +3(12) = 36 ≠ 24

B. 2(2) +3(9) = 31 ≠ 24

C. 2(3) +3(6) = 24 . . . . . a solution

D. 2(8) +3(0) = 16 ≠ 24

If the dimensions of the following cylinder are quadrupled, what will be the volume of the new similar cylinder?

Alik [6]

Answer: First option is correct.

Explanation:

Since we have given that

Radius = 11 inches

Height = 14 inches

Now, according to question, we have mentioned that all the dimensions of the cylinder is to be quadrupled i.e. four times.

Then,

Radius is given by

$4\times 11=44 inches$

Height is given by

$14\times 4=56\ inches$

As we know the formula for " Volume of cylinder ":

$V=\pi r^2h\\\\V=3.14\times 44\times 44\times 56=340426.24\ in^3$

Hence, our volume of new similar cylinder is 340426.24 cubic in.

Therefore, First option is correct.
