Answer:
8 bags of rye & bluegrass mix
10 bags of bluegrass
Step-by-step explanation:
RB = bags of rye & bluegrass mix
B = bags of bluegrass
348B + 255RB = 5334
RB+B = 18 then RB = 18-B
substitute for RB
348B + 255(18-B) = 5334
348B + 4590 - 255B = 5334
reduce
93B = 744
B = 8
RB = 10

Jason owns a cabin that he rents to people for a maximum of 21 nights. He uses the function f(x) = 175x + 50 to calculate the rental cost for nightsWhat is the domain for the function in this context?
Answer:
domain: all natural numbers greater than zero and less than or equal to 21
Step-by-step explanation:
You cannot go for zero nights, and the maximum number of nights you can stay is 21. You also cannot have fractional night, so your answer has to be in natural numbers.

According to Wikipedia, the average weight of an adult male in the U.S. is 197.7 pounds with a standard deviation of 18 pounds, while the average adult female weighs 168.7 pounds with a standard deviation of 15 pounds. Both weights vary according to a Normal distribution.
7.) If you randomly selected one adult woman, what is the probability that her weight exceeds (is higher than) 130 pounds?
Suppose you randomly selected one adult male and one adult female from the entire U.S. population. Let the variable D = the difference in their weights (male – female).
8.) Calculate and interpret the mean of D.
9.) Interpret your answer from #8 in context.
10.) Calculate the standard deviation of D.
11.) Calculate the probability that the randomly selected male would weigh less than the randomly selected female.
Expand and simplify (x+5) (x+5)
Answer:
x² + 10x + 25
Step-by-step explanation:
To expand two quantities, we need to distribute each value in each quantity.
For example:
Start with multiplying the x in the first quantity with the x in the other quantity.
(x+5)(x+5) = x²...
Then multiply the x in the first quantity with the 5 in the other quantity.
(x+5)(x+5) = x² + 5x...
Repeat with the 5 in the first quantity.
(x+5)(x+5) = x² + 5x + 5x +25
Combine like-terms to simplify.
x² + 10x + 25
Answer:
x^2+10x+25 or (x+5)^2
Step-by-step explanation:
(x+5)(x+5)
Multiply x+5 and x+5 to get (x+5)^2 .
(x+5)^2
Use binomial theorem (a+b)^2 =a^2 +2ab+b^2 to expand (x+5)^2 .
x^2+10x+25

To eliminate the x terms and solve for y in the fewest steps, by which constants should the equations be multiplied
by before adding the equations together?
First equation: 6x-5y=17
Second equation: 7x + 3y = 11
The first equation should be multiplied by 3 and the second equation by -5.
O The first equation should be multiplied by 3 and the second equation by 5.
O The first equation should be multiplied by 7 and the second equation by -6.
The first equation should be multiplied by 7 and the second equation by 6.
Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.
Simultaneous equation6x - 5y = 17
7x + 3y = 11
Using elimination method
Multiply equation (1) by 3 and (2) by 518x - 15y = 51
35x + 15y = 55
Add the equation18x + 35x = 51 + 55
53x = 106
x = 106/53
x = 2
Substitute x = 2 into6x - 5y = 17
6(2) - 5y = 17
12 - 5y = 17
-5y = 17 - 12
-5y = 5
y = 5/-5
y = -1
Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1

Hope this helps! :)
Answer: B. (5,11)
Step-by-step explanation:
c = 6 + 1s In this case we know that c is your total cost and s is the number of downloaded songs.
If we were to do it in terms of x and y, y will be c, and x will be s.
Now is asking for the cost of 5 songs, so you will input the value 5 into the equation for s and solve for c.
c = 6 + 1(5)
c = 6 + 5
c = 11
Now we know that for 5 songs it will cost you $11, and if x is the same as the number of songs, and y is the total cost then we can say that the point will be,

Answer:
Step-by-step explanation:
First you have to multiply both sides by 4
4 (3x - 1) by 4 > 3 x 4
Then simplify it:
3x-1 > 12
Now add one to both sides
3x - 1 + 1 > 12 + 1
Then simplify it again:
3x > 13
Now divide both sides by 3
3x ÷ 3 > 13 ÷ 3
Answer:
x = 13 ÷ 3

We wish to determine the proportion of small- to medium-sized streams in eastern North Carolina which have runoff from hog farms in order to prepare for issues arising from water quality in the aftermath of hurricanes. A random sample of 242 small- to medium-sized streams is selected and it is found that 55 of them have runoff from hog farms. Which of the following is the value of the parameter of interest in this setting?
a. 0.555
b. 0.03298
c. 0.445
d. The value of the parameter of interest cannot be determined from the given information.
Answer:
The value of the parameter of interest in this setting is:
d. The value of the parameter of interest cannot be determined from the given information.
Step-by-step explanation:
To determine the parameter of interest in this setting, we need information about the population figure of the small-to-medium-sized streams in eastern North Carolina. We also require the population proportion of these streams, which have runoff from hog farms. But in this situation, the information is lacking. Instead, we are given information about the sample, which only produces statistics. For example, we can calculate the average (mean) proportion of the sample of 242 small-to-medium-sized streams using the 55 that were found to have runoff from hog farms.

Two friends are playing the same games on their phones. One is already on level 6, and levels up two hours. Her friend is on level 3, but levels up every 60 minutes. After how many will they have reached the same level? What level that be?
Answer:
6 hours level 9
Step-by-step explanation:
The number of hours after which both friends are on the same level is 6 hours.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
One friend:
At level 6 and every two hours, it levels up.
Another friend:
At level 3 and every hour, it levels up.
Now,
The number of hours after which both friends are on the same level.
6 + x/2 = 3 + x
6 - 3 = x = x/2
3 = x/2
x/2 = 3
x = 6
Thus,
After 6 hours both friends will be at the same level.

Answer:

Step-by-step explanation:
I had to look up 'balanced hanger' because that was not a term from my own math education, but I found it no problem.
See the attached picture.
There are 2 x's on the left and 4 1's on the right.
This means the equation has 2 x's on the left of the equal sign and 4 1's on the right.
Each unit of different size should be in a different shape.
The idea is that the hanger 'balances', just like a set of scales, or the same way an equation balances both sides.

the perimeter of a triangle is represented by 3x² +8x-9. Two of its sides are represented by (x²+11x+5) and (-2x²-4x+2) What expression would represented the third side
Answer:
The third side has a length of 4x² + x - 16
Step-by-step explanation:
We can solve this by taking the value given for the perimeter, and subtracting the values of the other two sides:
3x² + 8x - 9 - (x² + 11x + 5) - (-2x² - 4x + 2)
= 3x² + 8x - 9 - x² - 11x - 5 + 2x² + 4x - 2
= (3 - 1 + 2)x² + (8 - 11 + 4)x - (9 + 5 + 2)
= 4x² + x - 16
