Answer: If 36/7 is one of the options, choose that one.

If the question involves an exponent, you should use the "caret" which is ^ found above the 6 on a keyboard. [Shift + 6]. That helps avoid confusion.

Step-by-step explanation: 7 is equal to 35/5 because 7×5=35

Add 1/5 and you end up with 36/5. A Common rational number.

7^(1/5) = the 5th root of 7. A very small irrational number!

Find the fraction of stundents enrolled in each language

blondinia [14]

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$

Solution:

Total number of students = 51 + 33 + 42

= 126

Number of students enrolled in Chinese = 51

Fraction of students enrolled in Chinese

$$=\frac{\text{Number of students enrolled in Chinese}}{\text{Total number of students}}$

$$=\frac{51}{126}$

Fraction of students enrolled in Chinese = $\frac{51}{126}$

Number of students enrolled in French = 33

Fraction of students enrolled in French

$$=\frac{\text{Number of students enrolled in French}}{\text{Total number of students}}$

$$=\frac{33}{126}$

Fraction of students enrolled in French = $\frac{33}{126}$

Number of students enrolled in Spanish = 42

Fraction of students enrolled in Spanish

$$=\frac{\text{Number of students enrolled in Spanish}}{\text{Total number of students}}$

$$=\frac{42}{126}$

Fraction of students enrolled in Spanish = $\frac{42}{126}$

A certain family can afford a monthly mortgage payment of $1,340.00. With an APR of 5.25% per annum, what is the maximum mortgag

irina [24]

Answer:

$198,859.03

Step-by-step explanation:

The amortization formula is good for this. Fill in the given numbers and solve for the unknown.

A = P(r/n)/(1 -(1 +r/n)^(-nt))

where A is the monthly payment, P is the principal amount of the loan, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.

1340.00 = P(0.0525/12)/(1 -(1 +0.0525/12)^(-12·20)) ≈ 0.00673844·P

P ≈ 1340/0.00673844 ≈ $198,859.03

The family can afford a loan for $198,859.

Write the equation of the line that contains (8,0) and is parallel to the line -3x+4y=4

Kobotan [32]

Answer:

y = (3/4)x - 6

Step-by-step explanation:

if line is parallel to -3x + 4y = 4, that means that they both have the same slope

Slope of that second line is 3/4.

now time to find the y-intercept

0 = 3/4*8 + b

therefore, b = -(3/4)*8 = -3*2 = -6

Therefore, equation of line is y = (3/4)x - 6

Part 1:

emmasim [6.3K]

Here are my answers to the given questions above:
Part 1. Here is my example of a real life scenario that describes what is happening. Let us say, I have 2 cookies and the bottle of milk costs 11 dollars, and 3 cookies and 4 bottles of milk cost 24 dollars.
Part 2.
y=11-2x
3x+4(11-2x)=24
3x+44-8x=24
-5x=-20
x=4
y=11-8
y=3
Therefore, each cookie costs 4 dollars, and a bottle of milk costs 3 dollars.
Hope this answer helps. Let me know if you need more help next time.
