Suppose that y varies directly as the square root of
x, and that y = 16 when x = 4. Find x when
y = 24.
Answer:
x is 6
Step-by-step explanation:
x is 1/4 of y. so divide 24 by 4 and get 6
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.

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].

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

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.

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

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
