Answer:

Colten took test reveiw on edge!

Step-by-step explanation:

Colton got the wrong answer

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Garcia’s students were asked to find 220% of 75, we need to find who did incorrect answer among Amy, Braden, Colton and Danielle

Amy multiplied 2.20 by 75 to find my answer.”

220/100×75=2.2

His answer is correct

Barden

Braden created table for 100, 100 and 20% and added. This will be equivalent to finding 220%

Braden is correct.

Colton created table for 100%, 10% and 10% percent and added these.

But this addition would result in 100+10+10 =120%  not 220%

Hence Colton is wrong.

Danielle divided 75 by 5 to find 20%.

Then he added 75 twice to find his answer.

Danielle is correct.

Hence Colton got the wrong answer

Answer:

The answer is 25 cups of apple juice and 10 cups of sparkling water

Step-by-step explanation:

5+2=7, 35/7=5, so you must multiply each ingredient by 5

Answer:

175 cups of apple juice and 70 cups of sparkling juice

Step-by-step explanation:

Answer:

98%

Step-by-step explanation:

Test 1 - 83%

Test 2 - 91%

Test 3 - 88%

Test 4 - ?

If we use x to represent Test 4, we can create the following equation:

1/4 (83 + 91 + 88 + x) = 90

We find the average here by adding up the four test scores and dividing by 4.

Proceed to solve it:

1/4 (262 + x) = 90

262 + x = 360

x = 98

Therefore, Sam needs to get a 98% to have and average of 90% on all four tests.

Answer:

Since there are 32 fluid ounces in 1 quart and we need 3 quarts we multiply 32 and 3 and get the result of which is 96 we need to divide that by eight to get the correct number to multiply 4.50 by so we get the result of 12 now it is 12 times 4.50 which is 54 so it costs 54 dollars.

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function

The sum of the coordinates of the point is 7.25

The reason the above values are correct is as follows;

The given parameter is;

The point (9, 7) is on the graph y = f(x)

Required:

A point on the graph, 2·y = (f(2·x)/2) + 2

Solution:

Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;

f(2·x) = f(2 × 9/2) = f(9) = 7

Therefore;

2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5

y = 5.5/2 = 2.75

y = 2.75

The coordinate of the point is (x, y) = (2.75, 9/2)

The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

Answer:

1. QS and RT= 15

2. Im not positive but I think it's TQ=18

Step-by-step explanation:

For question 1, you would do 6x+3=8x-1 and solve to get the result of x=2

Then you'd plug in 6 and get QS and RT=15

For the second one I am unsure because I wasn't positive how to solve but it seems like the side RQ might be 1/2 of TQ. Sorry if thats wrong I can try and help more if you need

Answer:

He can wire

[tex] \frac{1}{4} [/tex]

of a room with 3/4 of a roll of wire.

Step-by-step explanation:

We can solve by using proportions.

Let's set it up.

[tex] \frac{3 \: rolls}{1 \: room} = \frac{ \frac{3}{4} \: of \: a \: roll}{x} [/tex]

We are now going to cross multiply. By cross-multiplting, you would get:

[tex] \frac{3}{4} = 3x[/tex]

You are now going to divide both numbers by 3 in order to get the x by itself.

[tex] \frac{ \frac{3}{4} }{3} = \frac{3x}{3} [/tex]

By dividing, you get:

[tex] \frac{1}{4} = x[/tex]

Therefore, the answer is 1/4.

The number of rooms he can wire with 3/4 of a roll of wire is 1/4.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Given that, an electrician needs 3 rolls of electrical wire to wire each room in a house.

Let the number of rooms he can wire with 3/4 of a roll of wire be x.

Now, the proportion is

[tex]\frac{3}{1}=\frac{\frac{3}{4} }{x}[/tex]

3x=3/4

x=1/4

Therefor, number of rooms he can wire is 1/4.

The number of students in the group are 17.

Two or more expressions with an Equal sign is called as Equation.

Given that a group of adults and students buy tickets for a dance performance.

The cost of each ticket is $4.65.

The total cost of the tickets for the group is $93.00.

There are exactly 3 adults in the group

We need to find  the number of students in the group.

Let x be the number of students.

3(4.65)+4.65x=93

13.95+4.65x=93

Subtract 13.95 on both sides

4.65x=93-13.95

4.65x=79.05

Divide both sides by 4.65

x=17

Hence, the number of students in the group are 17.

This is one slight annoyance when it comes to sig figs, in my opinion anyway. You did the steps correct. The 639 bumps up to 640, so 6396 rounds to 6400 when rounding to 3 sig figs.

Normally the trailing zeros, ie zeros on the right, are not significant. So 6400 shows only 2 sig figs. What we need to do is draw a horizontal line over the first zero to show that it is significant (while the other zero is not significant)

So you'll write it like this [tex]64\overline{0}0[/tex]

This notation can be problematic when it comes to decimals because it could be easily mixed up with the repeating decimal notation.

When you convert [tex]64\overline{0}0[/tex] to scientific notation, you would get [tex]6.40 \times 10^3[/tex].

In short: [tex]64\overline{0}0 = 6.40 \times 10^3[/tex]

Here the zero is significant because the zero is present in the scientific notation result. Writing [tex]6.4 \times 10^3[/tex] shows 2 sig figs while [tex]6.40 \times 10^3[/tex] has 3 sig figs.

It's similar to how the number [tex]5.7[/tex] has 2 sig figs while [tex]5.70[/tex] has 3 sig figs. While the zero is trailing, having it after a decimal point indicates to the reader that you achieved this level of accuracy.
