Evaluate and simplify each square root(simplest form). To create a square root symbol type sqrtt.

Answers

All this is, is plugging in numbers. Then taking the square root of it. The first one would be the square root of 6 squared - 4(5)(-3). That would simplify to the square root of 36+60. Then add the numbers to get the square root of 96. The square root of 96 is about 9.798. I hope that helped. If you still need help with the second one or with the rest of the formula (if there is one) just ask!

A 64-ounce container of sports juice costs $6.50. A 48-ounce container of the same juice costs $4.25. Which juice container is the better buy.

Answers

Answer:

The juice container that is a better buy is the 48 ounce container because the price per ounce is lower.

Step-by-step explanation:

In order to determine the juice container that is the better buy, you have to find the one that has a lower cost per ounce by dividing the price of each juice container by the number of ounces it has:

64-ounce container: 6.50/64=0.10

48-ounce container: 4.25/48=0.08

According to this, the answer is that the juice container that is a better buy is the 48 ounce container because the price per ounce is lower.

The Hendricksons are in charge of bringing treats for 50 football players. They brought 3 coolers of popsicles and 2 coolers of ice cream sandwiches. Each player is going to randomly select a cooler from which to get their treat. Which statement best predicts how many players will get a popsicle?

Answers

3/5 of the players (30 players) will get a popsicle.

There are 5 coolers in total. There are 3 coolers of popsicles, which means 3/5 of the coolers are popsicle coolers.

To find out how many football players will get a popsicle, multiply the amount of football players (50) by the chance they will pick a popsicle cooler (3/5).

50 x 3/5 = 30 football players

Answer:

There will be close to 30 football players but probably not exactly 30 football players who get a popsicle.

How can you use the DISTRIBUTIVE PROPERTY solve the equation: 3(x-4) = 24 ? *

Answers

By using the Distributive Property, you would multiply 3 into the parenthesis (3 · x and 3 · -4)

3(x - 4) = 24

3x - 12 = 24

Then, you would solve like any normal one-step equation.

3x - 12 = 24

     +12   +12

__________

3x      36

__  =  __

3        3

x = 12, which is your final solution.

If you need any further explanations, please ask me :)

Answer:

3(x - 4) = 24 This is the normal equation.

3x - 12 = 24 Next, use the distributive property and multiply everything in the parentheses by the number on the right of the parentheses, which in this case is 3. 3 times x is 3x, and remember to use any symbols to the left of the numbers and use as if it was a negative. 3 times -4 -12. Get rid of the parentheses and replace with the new numbers, which are 3x and -12.

3x = 36  I think you are solving for X so that's what i'm doing.

x = 12

Please help with an explanation ​

Answers

Answer:

n = 6

Step-by-step explanation:

To isolate n, subtract 1 from both sides:

4n + 1 = 25

4n = 24

Then divide by 4 on both sides:

4n = 24

n = 6

Hope this helped :)

Answer:

6

Step-by-step explanation:

4n+1= 25

or,4n= 25- 1

or,4n=24

or,n=24/4

so n= 6

5n+3=18

Answers

Answer:

n=3

Step-by-step explanation:

5n+3=18

subtract 3 from both sides

5n=15

divide by 5 on both sides

n=3

Answer:

n=3

Step-by-step explanation:

step 1- subtract 3 to both sides

+3-3=0    18-3=15

5n=15

step 2- divide both sides by 5

5÷5=1       15÷5=3

step 3- check answer by plugging in for n

5(3)+3=18

15+3=18

18=18

Simplify the expression -(6 - 4p)

Answers

Hey there!

The answer to your question is [tex]-6+4p[/tex]

Given:

[tex]-(6-4p)[/tex]

First, we distribute the negative sign to both terms ([tex]6[/tex] [tex]and[/tex] [tex]-4p[/tex]) This would make the [tex]6[/tex] negative and the [tex]-4p[/tex] positive, so we have:

[tex]-6[/tex] [tex]and[/tex] [tex]4p[/tex]

Add them together and we get:
