Cameron's hourly salary is $13. If Cameron
gets to work in the morning at 9 has lunch
from 12 to 1. and then works until 2. then hou
much did Cameron make that day?
Answer: 52 dollars
Step-by-step explanation:
Cameron's hourly salary is 13, which means that for each hour she works, she earns 13 dollars.
If she words from 9 - 12, then that is 3 hours. Then she has a lunch break from 12 - 1, and then works again until 2. The time period between 1 and 2 o'clock is 1 hour.
Now we have to add up the total hours that Cameron works. If she worked 3 hours in the morning, and then 1 hour after lunch, then the total is 4 hours. Now we have to mutliply 4 by 13 to find her salary for that day.
4 x 13 = 52. Therefore, Cameron made 52 dollars that day.
6. At the Winter Olympics, the ratio of Canadian medals to US to Russia was 1:8:5. If Russia won 25
medals, how many did Canada and US won?
Answer:
Step-by-step explanation:
Let x be the total number of medals won by the Russians.
The way to do this is to add the ratios together
1 + 8 + 5 = 14
(5/14) x = 25
Multiply by 14
5*x = 25 * 14
5x = 350
divide by 5
70
8/14 = x / 70
14x = 8 * 70
14x = 560
x = 560 / 14
x = 40
The USA won 40 medals.
1/14 = x / 70
14x = 70
x = 5
Canada Won 5 medals.
Check
Russia Won 25 medals
Canada Won 5 medals
USA Won 40 medals
Total 70

x is 1/4 of y. so divide 24 by 4 and get 6
find the following square by using the identities
[tex](2xy + 5y) {?}^{2} [/tex]
Given:
Consider the given square is
[tex](2xy+5y)^2[/tex]
To find:
The value of given square by using the identities.
Solution:
We know that,
[tex](a+b)^2=a^2+2ab+b^2[/tex] ...(i)
We have,
[tex](2xy+5y)^2[/tex]
Using the identity (i), we get
[tex](2xy+5y)^2=(2xy)^2+2(2xy)(5y)+(5y)^2[/tex]
[tex](2xy+5y)^2=4x^2y^2+20xy^2+25y^2[/tex]
Therefore, the value of given square expression is [tex]4x^2y^2+20xy^2+25y^2[/tex].

Find the Least Common Multiple
The left denominator is : 4
The right denominator is : 6
Number of times each prime factor
appears in the factorization of:
Prime
Factor Left
Denominator Right
Denominator L.C.M = Max
{Left,Right}
2 2 1 2
3 0 1 1
Product of all
Prime Factors 4 6 12
Least Common Multiple:
12
Calculate multipliers for the two fractions
Denote the Least Common Multiple by L.C.M
Denote the Left Multiplier by Left_M
Denote the Right Multiplier by Right_M
Denote the Left Denominator by L_Deno
Denote the Right Multiplier by R_Deno
Left_M = L.C.M / L_Deno = 3
Right_M = L.C.M / R_Deno = 2
Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction, multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 9 • 3
—————————————————— = —————
L.C.M 12
R. Mult. • R. Num. 17 • 2
—————————————————— = ——————
L.C.M 12
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
9 • 3 - (17 • 2) -7
—————— = ——

Step-by-step explanation:
Julio bought 7 science fiction novels (s) and 7 comic books (c) from the bookstore. His purchases can be represented by the expression 7(s + c). Part A: Simplify the expression by using the distributive property. Part B: The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. What is the total amount that Julio spent at the bookstore? Round your answer to the nearest cent. Show your work.
Answer: See explanation
Step-by-step explanation:
A. 7(s + c)
= 7s + 7c
B. The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. The total amount that Julio spent at the bookstore would be calculated as:
= 7s + 7c
= 7($5.99) + 7($6.49)
= $41.93 + $45.43
= $87.36
We then add tax which will then be:
= $87.36 + (6% × $87.36)
= $87.36 + (0.06 × $87.36)
= $87.36 + $5.24
= $92.60

Answer:
D. 48
Step-by-step explanation:
In the experiment, 16/40 landed exactly on heads. If you do 16/40 * 3/3 = 48/120.
This means that you can estimate 48 of the next 120 trials have 2 coins showing heads.
Yun Sil added twice as many new songs on her MP3 player as Matt, who added 5 more new songs on his MP3 player than Sierra. The sum of the
songs added on all three players is 15 more than the cube of the number of songs added on Sierra's player. About how many songs are on each
person's player?
Answer:
Sierra=2songs
Matt=7songs
Yun SIl=14songs
step-by-step explanation:
Step 1
Let,The number of songs YunSil added = x
Number of songs Matt added = y
And number of songs Sierra added = z
Such that Matt has 5more than Sierra =y = 5 +z
Yun SIl has 2 times more thann Matt, x = 2y
x =2(5+z)=10 +2z
Step 2
The expression used to determine number of songs on each player given that the total of songs added on the three players =15 +z^3
Such that
YunSil+Matt+Sierra==15 +z^3
10+2z+ 5+z +z = 15 +z^3
4z +15 = 15 +z^3
4z=15-15+z^3
4z=+z^3
4=z^3/z
4=z^2
Z=√4 =2
Therefore Sierra has z=2songs
Matt has 5+z=5+2=7songs
YunSil has 2(5+z)= 2x7=14songs
The song that are on each person player are as follows;
matt song = 7
Yung Sil song = 14
Sierra song = 2
Let
a = Matt song added
b = Yun Sil song
c = Sierra song =
Therefore,
b = 2a
a = c + 5
(c + 5 + 2a + c) - c³ = 15
(2c + 2(c + 5) + 5) - c³ = 15
2c + 2c + 10 + 5 - c³ = 15
4c + 15 - c³ = 15
4c - c³ = 0
c³ = 4c
c² = 4
c = √4
c = 2
a = 2 + 5 = 7
b = 2(7) = 14

Cindy is make a display for a project. She plans on 100 stickers that are 2 inch by 2 inch square on a poster board. The poster board she is using has a length of 3 feet and width of 2 feet. Does she have enough room for all her stickers
Answer:
YES
Step-by-step explanation:
the dimensions of the poster board has to be converted to inches to add comparability
1 feet = 12 inches
3 x 12 = 36 inches
width = 2 x 12 = 24 inches
Area = length x breadth
36 x 24 = 864 cm^2
area of sticker = 2 x 2 = 4cm^2
Number of stickers that can be put on the board = 864 / 4 = 216
216 is greater than 100. So the board has enough room for the stickers

1. What percent of 200 is 0.5?
Answer:
Step-by-step explanation:
My guess is % 1/400
Answer:
0.5 is 0.25% of 200.
Step-by-step explanation:
1 is 1/200 of 200.
Therefore, 0.5 is 1/400 of 200.
1/400 = 0.0025 = 0.25/100
Therefore, 0.5 is 0.25% of 200.
