She uses 2 1/2 cups of flour in one batch of her famous chocolate chip cookies.
She needs to bake 3 1/4 batches for her annual cookie swap. She has 7 cups of
flour at home.
Does she have enough flour?
If so, how much extra will she have? If not, how much
more does she need?
Answers
Answer:
No
Step-by-step explanation:
I did it
Answer:
She doesn't have enough flour
8 1/8 - 7 = 1 1/8 cups more of flour
Step-by-step explanation:
2 1/2 = 5/2
3 1/4 = 13/4
5*13 = 65
2*4 = 8
65/8 = 8 1/8
She doesn't have enough flour

How can Diego package all the 48 brownies and 64 cookies so that each bag has the same combination of items? How many bags can he make, and how many of each will be in each bag? Find all the possible ways to package both items.
I don't know how to do this, can someone please walk me through the process and help with the answer(s)?
Answers
Divide 48(brownies) by 2, you get 24, and if you divide 64(cookies) by 2, you get 32. So you will need 2 boxes ( since we divided both the numbers by 2 ) and each box will have 24 brownies and 32 cookies in each.
2nd way:
Divide 48( brownies) and 64(cookies) by 4, and you will get 12(brownies) and 16(cookies), so you will need 4 boxes with 12 brownies and 16 cookies in each since we divided the numbers by 4.
So basically, you can keep doing this until no more numbers equal to 48 or 64 when you divide them. And the number you divide them with is how many boxes you will need. Hope this helps.
Sam will take four science tests this quarter. Her scores on three of the tests are shown below.
What does Sam need to score on the fourth test to ensure that she will have an average of 90% for all four tests?
Answers
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.

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.

When I round 6396 to 3 significant figures, I get 6400. I was double checking my work and used scientific notation for 6400, which is 6.4*10³, but when I counted the significant figures in scientific notation, I only get 2, which are 6 and 4, but there were supposed to be 3. Anyone can help to explain?
Answers
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.

An electrician needs 3 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 3/4 of a roll of wire?
Answers
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.
What are proportions?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.

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%

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
