Say you're making a recipe that needs 2 1/2 cups of water. But you want to make two servings, so you need to know what 2 1/2 + 2 1/2 equals. Or maybe you need a half cup of milk but you don't have enough. You need to know how much left you need so you can buy or borrow the right amount.

False, False, True
**********
The first is false since the square root of 19 is 4 and 4/7 is not a whole number

The second is false since the square root of 40 is 6.32 which is less than 7

The last is true because the square root of 30 is 5.48 and that makes the fraction equal 3.65 which again is a whole number while 2/3 is not

A 5 person sports team has an average 40 yard dash time of 5. 7 seconds. When a 6th player is added to the team, the new mean is
DanielleElmas [232]

The new player's personal time  is 4.5 seconds.

<h3>What is the new player's personal time?</h3>

The first step is to determine the total time the 5 persons complete the dash.

Total time = 5 x 5.7 = 28.5 seconds

The second step is to determine the total time for the 6 people to complete the dash.

Total time = 6 x 5.5 = 33 seconds

The third step is to find the difference of the time in the previous two steps: 33 - 28.5 = 4.5 seconds

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand co
jok3333 [9.3K]

Answer:

76 mL of 8% and 304 mL of 13%

Step-by-step explanation:

Set up a table like this (this is the same table for any mixture problem):

                   mL total     *           % vinegar       =              % vinegar/mL

8%

13%

total %

What you do with this table is multiply the first 2 columns and they equal the last column.  We already know the middle column's entries from what we are given.  But remember that a percent needs to be expressed as a decimal:

                       mL total     *       % vinegar      =        % vinegar/mL

8%                                                 .08

13%                                                .13

total %                                  

Now we also know that the total he wants to make is 380 mL that is 12%, so all that info goes into the last row:

                      mL total       *       % vinegar        =        % vinegar/mL

8%                                                   .08

13%                                                  .13

total %            380                          .12

If he wants this total mixture to come from the 8% and the 13% vinegars, he is mixing them together, or adding them.  We need to know how much 8% + how much 13% will give us 380 mL of 12%.  So we can fill in the amounts accordingly.  If he has x mL of 8%, then he will have 380 - x of 13%.  The table tells us that we are multiplying the first 2 columns to get the third, so we will do that at the same time:

                       mL total         *          % vinegar        =        % vinegar/mL

8%                        x                *             .08                =          .08x

13%                 380 - x            *             .13                 =      .13(380 - x)

total %               380              *             .12                 =          45.6

Since we are adding the different vinegars together to get the total, we can do that with the last column as well.  This is our equation:

.08x + .13(380 - x) = 45.6  Multiply everything through by 100 to get rid of the decimals now:

8x + 13(380 - x) = 4560 and

8x + 4940 - 13x = 4560 and

-5x = -380 so

x = 76

This means that there is 76 mL of 8% and 380 - 76 = 304 mL of 13%

Please help. 10 points and brainliest.
Snezhnost [94]

Answer:

\frac{a^2}{b^2}

Step-by-step explanation:

Apply the exponent rule a^b*a^c=a^b+c to a

a^4*a^-^2=a^4^-^2=a^2

b^3a^2b^-^5

Apply the exponent rule to b

b^3*b^-^5=b^3^-^5=b^-^2

Apply the exponent rule a^-^b=\frac{1}{a^b}

b^-^2=\frac{1}{b^2}=\frac{1}{b^2}a^2=\frac{a^2}{b^2}
