Answer:
C) a gain of 72.47 points
Step-by-step explanation:
because on 1/28 it has 13,881.93 and the next day 1/29 it has 13,954.4
subtract 13,954.4 - 13,881.93= 72.47
72.47 is the greatest amount change
And it can’t be 93.98 because in the instructions it said one day to the next not 2 day’s in advance

4. y = 1/2x + 10
Courtney has $21.50 to buy a gift for her brother. She found a stuffed animal that costs $19.65. With 10.1% sales tax added on, what is the sales tax? What is the total cost of the stuffed animal with tax included? Will Courtney have enough money to buy the gift?
The sales tax is: $_________
The total cost is: $_________
Is it enough money?
Answer:
11.95
Step-by-step explanation:
21.50-19.65+ 10.1 = 11.95
Point U on a graph is located at (4,8), Point V on the same graph is located at (12, 14).
Which point lies on Line UV?
A. ( 7 , 12 )
B. ( 10 , 14 )
C. ( 16 , 22 )
D. ( 20 , 20 )
Answer:
D
Step-by-step explanation:
gradient is change in y/change in x
gradient of UV = 14-8/12+4=3/4
use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use one of the coordinates of U or V, I'll use (4,8)
[tex]y = mx + c[/tex]
[tex]8 = \frac{3}{4} (4) + c[/tex]
[tex] 8 = 3 + c[/tex]
c is 5
the equation for UV is
[tex]y = \frac{3}{4} x + 5[/tex]
insert each X coordinate given in the question to see if it gives the same y coordinate
when x is 20, y is also 20 so the answer is D
Explain, in detail, how you know if these are equivalent.
Answer:
they are equivalent.
Step-by-step explanation:
to find equivalent fractions, we need to multiply the numerator and denominator of the first fraction by the same number. this creates an equivalent fraction. 5 goes into 15 3 times, and 8 goes into 24 3 times. this shows that if we multiply both the numerator and denominator of the first fraction by 3, then we end up with the second fraction, proving that they are the same. hope this helps!
5/8. Each one you multiply by 3 is gonna be 15/24. 5 is a common factor of 15 and 8 is the common factor of 24

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.
________________________________________________
Kenzie has $7.25. What is the maximum number of scrunchies she can buy?
______________________________
Answer:
48
Step-by-step explanation:
20 scrunchies=3 dollars
7.25 dollars = ?
1 dollar=6.66666666
0.25 dollar=1.666666666666
7*6.66666666=46.666666
:)
Answer:
Kenzie can buy 48 Scrunchies
Step-by-step explanation:
You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.
I hope that helped :)

In this exercise we have to use the conditions given in the statement, that is, when adding the extreme pairs they must give the middle number, so the only number that follows this condition is:
The next year to have to same property will be 2307
are analyzing the condition given in the statement and the example we can buy as follows:
[tex]1978 \rightarrow 19+78= 97 \\2307 \rightarrow 23+07= 30[/tex]
so the year 2307 corresponds to the conditions given in the statement.

Two teams working together can finish a job in 8 days. if the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains. How many days will it take each team to finish the work alone?
x is the days that the first team finishes the work alone (x>8)
y --------------------------second-----------------------------------------(y>8)
In a day:
The first team finishes 1/x (the work) The second team finishes 1/y (the work) Two teams working together finish 1/8 (the work)⇒ [tex]\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}[/tex] (1)
If the first team works alone for two days and the second team works alone for 5 days, 5/8 of the total work still remains:
⇒ [tex]\frac{2}{x}+\frac{5}{y}=\frac{3}{8}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{1}{x}+ \frac{1}{y} =\frac{1}{8}} \atop {\frac{2}{x}+\frac{5}{y}=\frac{3}{8}}} \right. <=>\left \{ {{x=16} \atop {y=24}} \right.[/tex]
It'll take the first team 16 days and the second team 24 days to finish the work alone
ok done. Thank to me :>

The three oldest children need shoes. You find a store that has shoes on sale. All shoes in the store are marked $10 per pair. You have a choice of “Three for the price of two” or “Buy one and get 25% off the second.” Which of these is the best deal? Explain your reasoning.
Answer:
3 for the price of 2
Step-by-step explanation:
I had this question
Okay, they all equal 30 bucks. The first one would change into 20 bucks and the other would be Take off 10 by 30, 20, 20 with 25% off is 15. Then 15 + 10 is 25.
First one = 20.
Second one = 25.
Three for the price of two is cheaper.

A school assembly had 600 students in attendance, and 35% of them were first-graders. How many first-graders were at the assembly?
can u also list the formula on how to do this while ur at it pls and ty
Answer:
210 Were First Graders
Step-by-step explanation:
35 percent of 600 is the same as 35 per hundred of 600. We can therefore make the following equation:
35/100 = X/600
To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
35/100 = X/600
X/600 = 35/100
X*600/600 = 35*600/100
X = 21000/100
X = 210
The work above shows the long way to explain how to calculate 35 percent of 600 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 35 percent of 600?", Y is 600 and P is 35:
(600 * 35)/100 = 210
And once again you see that the answer is 210.
Answer:
210 kids
Step-by-step explanation:
So the formula is basically part over whole is equal to x/100%
So for here it would be x/600 = 35/100
Solve that and you will get 210
