Zahara mixed 5 quarts of dry ingredients and 2 quarts of water and a batch of concrete .She ran out of the mixture before finishing her project so she made another batch 10 quarts of dry ingredients . How many quarts of water does zahara need to add to keep the consistency the same? Complete the ratio square
Answer: 4 quarts.
Step-by-step explanation:
Given data:
Amount of dry ingredients = 5 quarts.
Amount of water in the mixture = 2 quarts.
Solution:
Let’s a represent the amount of dry ingredients.
Let b represent the amount of water
For first Batch
a/b = 5/2.
b = 2/5a ....... equation 1
For second Batch
a= 10
substitute a into equation 1 to solve for b
b = 2/5(10)
b = 4.
The ratio for batch b = 10/4.
Zahara needs to add 4 quarts of water to the mixture.
Answer:4 quarts!

Consider the two graphs above.
Which statement best describes the graphs?
A. Graph 1 represents a proportional relationship, but graph 2 does not.
B. Graph 2 represents a proportional relationship, but graph 1 does not.
C. Both graph 1 and graph 2 represent proportional relationships.
D. Neither graph 1 nor graph 2 represent a proportional relationship.
Answer:
B. Graph 2 represents a proportional relationship, but graph 1 does not.
Step-by-step explanation:
All proportional relationships pass through the origin. Graph 2 does but Graph 1 does not. Additionaly, Graph 2 is a straight line that represents a proportional relationship. Another way to find out if it is proportional is to find the constant of proportionality by dividing the y by the x in different parts of the line. The numbers should all have the same constant of proportionality.
Examples (all found in Graph 2):
15/3 = 5
10/2 = 5
5/1 = 5
Peter says, "If you subtract 12 from my number and multiply the difference by −7, the result is −175." What is Peter's number
Answer:
37
Step-by-step explanation:
let’s say peter’s number is x
(x-12)(-7) = -175
-7x + 84 = -175
-7x = -259
x = 259/7
x = 37
Answer:
The number is 37.
Step-by-step explanation:
-175 ÷ -7 = 25
25 + 12 = 37
You have to work backwards from -175 by doing the reverse of what peter did to get the original number.
The directions on a sewing pattern say to buy an extra 12.5% of fabric to account for error. Sam needs 2.75 yards of fabric to make a shirt, so he buys 2.4 yards. Choose the correct statement.
A.Sam bought the correct amount of fabric because he bought what was suggested.
B.Sam bought the correct amount of fabric because he needs less than 2.4 yards.
C.Sam did not buy the correct amount of fabric because he needs less than 2.4 yards.
D.Sam did not buy the correct amount of fabric because he should have bought 3.09 yards
Answer:
Sam should have bought 3.09 yards of fabric instead of 2.4 yards
So, Option D is correct.
Step-by-step explanation:
Total fabric needed by Sam = 2.75
According to directions on a sewing pattern they say to buy an extra 12.5%
So, extra fabric would be: 12.5% of 2.75
Solving
[tex]12.5\% \ of \ 2.75\\=\frac{12.5}{100}\times 2.75 \\=0.343[/tex]
Now adding 0.343 into 2.75 to get extra fabric quantity:
2.75+0.343
=3.09
Therefore Sam should have bought 3.09 yards of fabric instead of 2.4 yards
So, Option D is correct.

Chick-fil-A offers its customers a choice of regular and diet soda. Last night, Chick-fil-A served 50 sodas in all, 27 of which were regular. What percentage of the sodas were regular?
Answer:
54%
Step-by-step explanation:
We know Chick-fil-A served 50 sodas in all, 27 of which were regular. The fractional form of this is 27/50. Now, we can convert this to a fraction with a denominator with 100, then a percentage. 27/50 is equal to 54/100.
54/100 is 54%
Answer:
is 54.the max is 100 percent.the percentage of regular sodas is 54 percent.you do this by timing 50 and 27 by 2 to get 100 and 54.

A store buys a camera for $80 and decides to markup the price 35%. How much does the camera sell for?
Step-by-step explanation:
80$ is original price so 100%
markup by 35% make price 135%
crossmultiplication
ans=108
Based on the cost of the camera and the percentage markup, the selling price of the camera is $108.
The camera's selling price is 35% more than its cost price. That 35% is:
= 80 x 35%
= $28
The selling price of the camera is therefore:
= Cost of camera + Increase
= 80 + 28
= $108
In conclusion, the camera is being sold for $108.

OB. 1-1) = 7 - 21:
oc/) = 1 - 1
OD. (I) = 12 - 211
Answer:
Gah! Inverses!
Step-by-step explanation:
This is a pretty simple concept, just switch the x and f(x) values!
If you don't understand, look at how I solve it!
[tex]f(x)=\frac{1}{3} -\frac{1}{21} x[/tex]
Switching the positions of the x and f(x) values...
[tex]x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\[/tex]
Note: That f(x)^-1 is the proper notation for inverse functions.
[tex]x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7[/tex]
There you go!

3/5
all u have to do is find two point and count down and to the side basically find the distance of those two points to find the slope.
Answer:
3/5
Step-by-step explanation:
From what I can see two points of the line are (0,1) and (5,4) so you can just count and do rise/run which is y/x or the formula which is like y^2-y^1/x^2-x^1 they both get the same answer which is 3/5
If you plug the numbers into the formula it gives you 4-1/5-0 which is 3/5

Find the value of c that completes the square
x^2-x+c
Please help me with how to do this, and show me. Thank you.
Answer:
The value of c is 1/2
Step-by-step explanation:
We have to find the value of c that completes the square [tex]x^2-x+c[/tex]
So, completing square is of form: [tex]a^2-2ab+b^2=(a-b)^2[/tex]
In the question given the value c can be found by breaking the middle term. we are given -x while the general formula is 2ab for middle term so, our c = 1/2 i.e 2(x)(1/2) we get x so, solving:
[tex]x^2-x+c\\=x^2-2(x)(\frac{1}{2})+(\frac{1}{2})^2-(\frac{1}{2})^2\\=(x-\frac{1}{2})^2-(\frac{1}{2})^2[/tex]
The value of c is 1/2

The area of a circular garden is 121pi
square feet. How much fencing would
be needed to enclose the garden?
Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft
Answer:
1. Use area to find radius.
A = π r^2
121 π = π r^2
2. Divide each side by π.
121 = r^2
3. Take in the square root .
[tex]\sqrt{121} = \sqrt{r^{2} }[/tex]
11 = r
4. Find the circumference .
C = 2 × π × r
C = 2 × π × 11
C = 22 π ft
A total of 202 tickets were sold for a theatre showing. If child tickets cost $6 and adult tickets cost $10, how many tickets of each were sold if the theatre earned a total of $1708.
Answer:
167 adult tickets were sold
35 children tickets were sold
Step-by-step explanation:
Let the number of adult tickets be x
Let the number of children tickets be y
Total number of each ticket sold;
x + y = 202 equation 1
Total cost of the tickets
10x + 6y = 1708 equation 2
Let
x= 202 - y equation 3
Substitute 3 into 2
10(202 - y) + y = 1708
2020 - 10y + y = 1708
-9y = 1708 - 2020
-9y = -312
y= 35
Substitute y =35 into 1
x + 35 =202
x= 202 - 35
x= 167
Therefore;
167 adult tickets were sold
35 children tickets were sold
