RoseWind [281]

Answer:

Labels did she print is 36.

Step-by-step explanation:

Given : Ms kaimal prints out address labels on 3 sheets of paper each sheet is entirely covered in labels each label takes up \frac{1}{12} of a sheet.

To find : How many labels did she print ?

Solution :

\frac{1}{12} of a sheet takes up 1 label.

So, 1 of a sheet takes up  \frac{1}{\frac{1}{12}} label.

1 of a sheet takes up 12 label.

Then, 3 of a sheet takes up  12\times 3 label.

 3 of a sheet takes up 36 label.

Therefore, Labels did she print is 36.

Addie walked 2 1/2 miles in 45 minutes. Suzie covered 2 2/5 miles in 2/3 of an hour.
N76 [4]

Answer:

Suzie's speed was 3.6 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph (miles per hour)

x ----> the distance in miles

y ----> the time in hours

so

s=\frac{x}{y}

Find Suzie's speed

we have

x=2\frac{2}{5}\ mi

y=\frac{2}{3}\ h

substitute

s=2\frac{2}{5}:\frac{2}{3}

Convert mixed number to an improper fraction

2\frac{2}{5}=2+\frac{2}{5}=\frac{2*5+2}{5}=\frac{12}{5}

substitute

s=\frac{12}{5}:\frac{2}{3}=\frac{36}{10}=3.6\ mph

What is the second step in sketching the graph of a rational function?
Elodia [21]

Answer:

C. Choosing test numbers to the left and right of each of the function's zeros and finding the value of the function at each test number

Step-by-step explanation:

Rational function: In mathematics, the term "rational function" is determined as any specific function that can be described through any "rational fraction", in other words, an algebraic fraction, involving both the denominator and the numerator are considered as polynomials. Therefore, the coefficients of specific polynomials are ought not to be in rational numbers and can be considered in the K field.

In the question above, the given statement represents option C is correct.

If (-9,2) is on the graph of F(x), which point must be on the graph of the inverse function F^-1(x)
Paha777 [63]

Answer:

On the other equation, there would need to be the point (2, -9)

Step-by-step explanation:

This is because when we find the inverse equations, it is the same as simply switching the x and y values. So in the ordered pair, we would just change the order.

Solve for x: 3 over 3 x plus 1 over quantity x plus 4 equals 10 over 7x. (2 points)
riadik2000 [5.3K]
Let me see if I can decipher that :P

3/(3x)+1/x+4=10/(7x)  first we need to make all terms have a common denominator of 21x...

(21+21+84x)/(21x)=30/(21x)  multiplying both sides by 21x leaves you with

21+21+84x=30  combine like terms on left side

42+84x=30  subtract 42 from both sides

84x=-12  divide both sides by 84

x=-1/7
