Answers

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.

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?

Answers

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

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

Answers

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

Please help with this question (10 points)

Answers

Answer:

48 in.

Step-by-step explanation:

We know that the dimensions are 144 by 96.

144  = 96(quotient) + remainder,

144 = 96(1) + 48

Solution: side of largest square = 48

Step-by-step explanation:

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

—————— =   ——

       12                 12

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=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].

Lilian says that 25% of a number will always be less than 75% of any other number. Complete one inequality to support Lillian's claim and one to show that she is incorrect.

Answers

She is incorrect cause if we take the number 20 and take 25% of it it equals 5 so now 20 is only 15. They if we take 75% away from 20 is equals 15 so then we only have 5 from 20 left. Therefore she’s incorrect because 75% leaves 5/20 and 25% leaves 15/20. Hope that makes sense.

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?

Answers

I believe Cameron made 52 dollars

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.

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.

Answers

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
