Given m || n, find the value of x and y.
m(7x+13)
n(3y-17) (9x-19)
Answer:
[tex]9x - 19 = 7x + 13 \\ 2x = 32 \\ x = 16 \\ 3y - 17 + 9x - 19 = 180 \\ 9x + 3y = 180 + 17 + 19 \\ 9x + 3y = 216 \\ 3y = 216 - 144 = 72 \\ y = \frac{72}{3} = 24[/tex]

Kate has 3 quarts of a 5% sugar solution she wants to mix this with 2478% sugar solution and X quarts of a 12% sugar solution to make a 10% sugar solution how many quarts of a 12% sure solution to Katie‘s
Answer:
The volume of the 12% sugar solution required, 'X' for a given volume of the 8% sugar solution, 'Y' is;
X = (2·Y + 15)/2
When the volume of the 8% sugar solution, Y = 2 quartz, the volume of the 12% sugar solution required, X = 9.5 gallons
Step-by-step explanation:
The data of the sugar solutions are;
The volume of 5% sugar solution Kate has = 3 quarts
The volume of the 12% sugar solution = X
Let 'Y' represent the volume of the 8% sugar solution, we have;
The volume of the resultant solution, Z = X + Y + 3
The concentration of the resultant solution = 10%
0.05 × 3 + 0.08·Y + 0.12·X = 0.1·(X + Y + 3)
Solving gives the relationship between the volume of the 12% sugar solution, 'X', and the 8% sugar solution, 'Y' in quartz, as follows;
X = (2·Y + 15)/2
When the volume of the 8% sugar solution, Y = 2 quartz, we have;
X = (2 × 2 + 15)/2 = 9.5
Therefore, the volume of the 12% sugar solution Katie requires to make the 10% sugar solution is 9.5 quartz.

Mila and Nadia have R480 between them.
Mila has 7 times as much as Nadia.
How much does each of them have?
Answer:
Mila= 420 Nadia= 60
Step-by-step explanation:
Let's call Mila 7x. And x to Nadia. The two of them had a total of 480s.
Then we say 7x + x. Their total is 8x. So 480 = 8x. We divide both sides by 8. Here x = 60. Since Mila is 7x, we find Mila as 7.60 = 420, and since Nadia as x, we find Nadia as 1.60 = 60.

Math HW Mr Thompson May 24
Answers:
B) 0A) 27D) 50See the diagram below.C) 143================================================
Explanations:
Refer to the top left corner of the table. This is the intersection of the "less than 1 year" column and "antlers" row.Add up everything in the "1 year or older" column to get 12+15 = 27.There are 0+12 = 12 deer with antlers, and 23+15 = 38 deer with no antlers. I'm adding across the rows. This in turn means there are 12+38 = 50 deer total. You could also add across the columns, meaning we have 0+23 = 23 deer less than 1 years old, and 12+15 = 27 deer that are 1 year or older. So we have 23+27 = 50 deer total. The explanation is lengthy. There's not much room here so I'll explain in the section below. Refer to the table below as well.Dividing everything by 143 will help us get the values into percentages. For instance, 62/143 = 0.4336 = 43.36% approximately represents the number of people who wear a belt and also wear a watch (top left corner).-----------
Explanation for problem 4
We have 68 people who split the check out of 122 total. That leaves 122-68 = 54 people who don't split the check. These two values are the row totals for rows 1 and 2 in that order. So you'll have 68 at the end of row 1, and 54 at the end of row 2. Refer to the diagram below.
We have 56 people who prefer to skip dessert, meaning 122-56 = 66 people who order desert. We'll have 66 followed by 56 along the first two items in the bottom row. The grand total 122 is in the bottom right corner. The 122 is both in the total row and total column.
Then we're told that 50 people order desert and split the check. We had 68 people split the check, leaving 68-50 = 18 people who split the check, but didn't get dessert. For the first row, we have the values 50, 18, and 68. Note that 50+18 = 68.
In the second row, we must have the values 16, 38, and 54 in that order. The blank spaces are filled in using the same ideas as I've discussed in previous paragraphs.
The terms in gray boxes represent the totals, which would be left out when forming the table in your final answer. Meaning you'll have a 2x2 table instead of a 3x3 table.

Answer:
Step-by-step explanation:
the geo. mean is the nth root of the product of n numbers
Here there are two numbers; geo. mean is the square root of their product
g = √(16 * 36)
g = 4 * 6
g = 24
Geometric mean is the mean which is the average of a set of a product.
The geometric mean of the given numbers is 24.
What is geometric mean?Geometric mean is the mean which is the average of a set of a product.
It can be given as,
[tex](\prod_{i=1}^{n}x_i)^{1/n}=\sqrt[n]{x_1\times x_2\times x_3...........x_n}[/tex]
Here [tex]x_i[/tex] is the values of the average and [tex]n[/tex] is the number of values.
Given information-
The numbers given in the problem is 16 and 36.
The Geometric mean for the number 16 and 36 has to find out.

the cost of fencing a circular field at the rate of Rs 12. per metre is Rs 2640 . find the radius of the field
Radius = 35 m
Step-by-step explanation:Given:Cost of fencing circular field is Rs 2640 at rate of Rs 12 per metre.
To Find:What is the radius of the circular field ?
Solution:Let the radius of circular field be r metre.
Here , if we'll divide the total cost by per metre cost of fencing then we'll get circumference of the circular field.
★ Circumference = Total cost/Cost per metre ★➯ Circumference = 2640/12
➯ 220 m
As we know that , formula of circumference is
★ Circumference = 2πr ★
⟹ 220 = 2 × 22/7 × r⟹ 220 = 44/7 × r⟹ 220 × 7/44 = r⟹ 20 × 7/4 = r⟹ 5 × 7 = r⟹ 35 = rHence, the radius of circular field is 35 metre.
Answer:
Solution given:
total cost =Rs 2640
rate=Rs 12/metre
We have
circumference of circle =[tex] \frac{total cost}{rate} = \frac{2640}{12} [/tex]
2πr=220m
r=[tex] \frac{220}{2π} [/tex]=35.01
r=35m(approximately)
the radius of the field is 35m.

(Use 21

as an estimate for n.)
A. 7 meters
B. 11 meters
C. 22 meters
D. 44 meters
Answer:
C. 22
Step-by-step explanation:
C = circumference
n (pi) = 22/7
r = 3 1 /2
Plug in the numbers for each variable.
C = 2x (22/7) x (3 1/2)
Change the mixed number inIto an improper fraction by multiplying 3 x 2 and adding the 1 which gives us 7 over 2 because 2 is our denominator so, 3 1/2 = 7/2. It also helps to have 1 as the denominator for 2.
C = (2/1) x (22/7) x (7/2)
Lastly, just multiply the numerators across which give us 308 then multiply the denominators across which gives us 14, so then we divide 308 by 14 and get 22.

Answer:
21.91 meters
Step-by-step explanation:
Since they already give you the hypotenuse, you will find the other missing side using this formula:
A= [tex]\sqrt{c^2 - b^2}[/tex]
So c² = 1,156
and b² = 676
1156 - 676 = 480
------
The square root of 480 is around 21.91
Let's double check, to double check, pretend that you don't know the hypotenuse, but you know the a and b sides.
So: 480.05 + 676 = 1,156.05
[tex]\sqrt{1156.05}[/tex] ≈ 34
