Given:
Ratio of white shapes to black shapes is 5:11
Ratio of white circles to white squares is 3:7
Ratio of black circles to black squares is 3:8
To find: fraction of all the shapes that are circles
Solution:
As ratio of white shapes to black shapes is 5:11,
let number of white shapes be 5 k and number of black shapes by 11 k
As ratio of white circles to white squares is 3:7,
Number of white circles = [tex]\frac{3}{10}(5k)=\frac{3}{2}k[/tex]
Number of white squares = [tex]\frac{7}{10}(5k)=\frac{7}{2}k[/tex]
As ratio of black circles to black squares is 3:8,
Number of black circles = [tex]\frac{3}{11} (11k)=3k[/tex]
Number of black squares = [tex]\frac{8}{11}(11k)=8k[/tex]
Total number of circles = [tex]\frac{3}{2}k+3k=\frac{9}{2} k[/tex]
Total number of shapes = [tex]5k+11k=16k[/tex]
Therefore,
Fraction of circles [tex]=\frac{\frac{9}{2} k}{16k} =\frac{9}{32}[/tex]
Alex works as a nanny. Her regular hourly wage is $10.25. If she regularly works 28 hours per week, what is her regular weekly pay?
Answer:
She normally gets $287 a week
Step-by-step explanation:
Answer:
$287 per week
Step-by-step explanation:
If she gets paid $10.25 per hour, and she works 28 hours in one week you'd have to multiply the two values to find how much she gets paid every week. 10.25 x 28 = 287
(Honestly, that's pretty good as a nanny lol)
Hope that helps and have a great day!
A golfer earned the following scores over several rounds of golf: −3, 2, 0, −1, 2, −4. Jamar says these numbers can all be described as integers, while Sophia says they are whole numbers. Which student is correct? Explain how you know.
Answer: Jamar is correct
Step-by-step explanation:
Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.
A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.
From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.
Joanne slices a large banana bread into 12 pieces. There are 2 adults and 2 children who get a piece of banana bread. The rest of the pieces will be donated to the homeless. What fraction of the banana bread will be donated?
Answer:
⅔ of the banana bread will have been donated
Step-by-step explanation:
12 pieces of banana bread
4 pieces were eaten
12-4=8
8/12 is simplified into ⅔

Expression is Blue
Coefficient is Red
Term is Green
Equation is Black
Step-by-step explanation:
It is a funny problem
Let us revise the meaning of the given names
Constant: It is a numerical termVariable: it is an unknown quantityExpression: it is a mathematics statement with a minimum of two terms and at least one math operation.Coefficient: it is the number of the variableTerm: it is formed from a variable or a number or both multiplied togetherEquation: it is formed from two equal sidesEx:
3 x² + 5x + 7 = 2a - 5 are called equation
[3x² + 5x + 7] and [2a - 5] are called expressions (algebric expression)
[3x²], [5x], [2a] are called terms
[x], [m] are called variables
[7], [-5] are called constants
[3], [5], [2] are called coefficients
Let us answer the question
52x² - 9x + 36 is an expression ⇒ Blue
9x is a term ⇒ Green
7 is a coefficient ⇒ Red
82 is a constant ⇒ Purple
m is a variable ⇒ Grey
52x² - 9x + 36 = 7m + 82 is an equation ⇒ Black

200 applicants applied to volunteer at an international tennis tournament. 14 of the applicants were successful. However, of the successful applicants, 15 couldn't make all the training sessions and were discounted. How many were selected to help at the tournament?
Answer:
The statement is a False statementStep-by-step explanation:
This question is somewhat lacking in detail or the information is not properly delivered/presented, this can be seen in the two statements bellow
1. 14 of the applicants were successful
2. Of the successful applicants, 15 couldn't make all the training sessions.
The two statements cannot hold true especially statements two, because if 14 volunteers were successful, then 15 volunteers cannot be selected from 14.

Catherine earns a yearly salary of $75,000. Lola earns a yearly salary of $80,000. Catherine will receive a salary increase of $4,800 per year, and Lola will receive a salary increase of $3,900 per year.
Which equation can be used to find n, the number of years it will take Catherine to earn the same salary as Lola?
A - 75,000 + 4,800n = 80,000 + 3,900n
B - 75,000n + 4,800 = 80,000 + 3,900n
C - 75,000n + 4,800n = 80,000n + 3,900n
D - 75,000n + 4,800 = 80,000n + 3,900

polynomial example
example of a polynomial
this one has 3 terms
To add polynomials we simply add any like terms together ... so what is a like term?
Like Terms
Like Terms are terms whose variables (and their exponents such as the 2 in x2) are the same.
In other words, terms that are "like" each other.
Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.
Example:
7x x -2x πx
are all like terms because the variables are all x
Example:
(1/3)xy2 -2xy2 6xy2 xy2/2
are all like terms because the variables are all xy2
Example: These are NOT like terms because the variables and/or their exponents are different:
2x 2x2 2y 2xy

3 blue marbles, 2 red marbles, and 5 yellow marbles. What is the ratio of red to total?
Answer:
1:6
Step-by-step explanation:
I'm good at ratio
Answer:
2:10
Step-by-step explanation:
We know that the number of red marbles is 2 so all we need to do is add up all the marbles to find the total so that equation would be 3+2+5 and that equals 10. Since we are comparing red to total the number of red would come first and the total after that so the ratio would be 2:10.

Step-by-step explanation:
Imagine that you randomly select a sample of 30 newborn infants and find that their mean weight is 8.1 pounds. The population mean of newborn infants is known to be 7.4 pounds with a standard deviation of 1.1 pounds. Would a sample mean as large as 8.1 be more or less likely if N = 10? Why?
Answer: more likely
Step-by-step explanation:
Given that :
Population Mean = 7.4
Population standard deviation = 1.1
Sample mean with a sample size of 30 = 8.1
A sample mean of 8.1 will be more likely with a sample size (N) of 10 because, the sampling distribution gets wider with decreasing sample size and narrower with larger sample sizes, hence, sample mean seems to conform with the population mean when the sample size are very large according to the central limit theorem. Hence, since a sample size of 30 results in a sample mean of 8.1, reducing the sample size will either give a similar sample mean or a sample mean further away from the population mean.
10+6x = 15+9x-3x
is this one solution, no solution, or multiple solution if one of 2 please tell me what is x
Answer:
No solution
Step-by-step explanation:
Let's solve this equation to see if there are any solutions.
First we need to simplify it;
10 + 6x = 15 + 9x - 3x
Combine like terms:
6x - 9x + 3x = 15 - 10
0x = 5
0 = 5
Zero cannot be equal to 5, so there is no solution

I NEED HELP ASAP
Answer:
27/30
Step-by-step explanation:
we need to find the common denominator of 5 and 2. Which is 10. We multiply the factors of the denominators by the numerator. This results in 1/10. Now, we subtract 2/3 from 1/10. We need to find common denominators also. Which is 30. 20/30 minus 3/30 is 27/30

2. A drink recipe calls for orange juice and pineapple juice. This equation represents the proportional relationship
between the number of cups of orange juice (r) and pineapple juice (p) in the recipe.
3r= 12p
What is the number of cups of orange juice used for 1 cup of pineapple juice?
a. 1/4
b. 3
c. 4
d. 12
Answer:
a. 1/4
Step-by-step explanation:
3r=12p
Divide the left side by 12 to get 1 cup of pineapple juice.
3r=12p
---- = p
12
So now you have
3r=p
BUT you have to divide BOTH sides by 12 so
3r=p
---
12
NOW you have
3/12 r = p
Simplify.
1/4r = p
So 1 cup of pineapple juice is equivalent to a quarter cup of orange juice!
