Circle the letter that is true about the grain size in rock

You're given two side lengths of 3 centimeters and 5 centimeters. Which measurement can you use for the length of the third side

igomit [66]

Answer: To find the third side of a triangle (there are two answers you could get), you need to use the Pythagorean formula: a^2+b^2=c^2. First answer, 3^2+5^2=c^2. Solve for c. c=5.83. The second answer, 3^2+b^2=5^2. Solve for b. b=4.

Each year Lizzie’s school purchases student agenda books, which are sold in the school store. This year, the school purchased 35

Stells [14]

The school can charge $7.54 for each agenda book.

Step-by-step explanation:

Given,

Purchase price of 350 books = $1137.50

Profit they want to make = $1500

Total amount = 1137.50 + 1500 = $2637.50

Therefore;

The school must sell 350 books for $2637.50

Thus,

350 books = 2637.50 dollars

1 book = $\frac{2637.50}{350}$

1 book = $7.535

Rounding off to nearest cent

1 book = $7.54

The school can charge $7.54 for each agenda book.

Answer:

The tap drains approximately half the water from the tank in 15 minutes

The tank initially has 50 gallons of water

Step-by-step explanation:

The tap drains approximately half the water from the tank in 15 minutes. True.

This is true because see that the point (15,25) lies on the graph of the line.

Which means after 15 minutes the amount of water left in the tank is 25 gallons and 25 is half of 50.

The tap drains exactly one gallon from the tank every minute. False

This is false because the slope of the graph is $m=\frac{50-25}{0-15}=-\frac{5}{3}$

The tank initially has 30 gallons of water. False.

The y-intercept is the initial gallons of water which is 50.

The tank initially has 50 gallons of water. True.

The y-intercept is the initial gallons of water which is 50.

The tank takes 50 minutes to drain completely. False.

It is false because the x-intercept tells us the tank is drained completely and it is not 50 minutes but rather 30 minutes.

2 tons of mulch cost $14,720.00. What is the price per pound?

Norma-Jean [14]

Answer:the anser is $7,360

Step-by-step explanation:

all you need to do is divide 14,720 by 2 to get 7,360 because you are needing to know how much is one pound of mulch and you have twice the mount so all you need is to divide :)
