You will need 16 dollars
Step-by-step explanation:
Since there are 3 feet in a yard divide the 6 by three that will be 2 dollars per foot. Then 2×4 equals 8. Take the 8 and multiply it by 2 then you will get the total of 16 dollars

What is the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line represented by y=34x−8?
Answer:
The equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]Step-by-step explanation:
We know the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Given the line
[tex]y=34x-8[/tex]
comparing with the slope-intercept form of the line equation
The slope m = 34
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 34
Thus, the slope of the the new perpendicular line = – 1/m = -1/34 = -1/34
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values of slope = -1/35 and the point (12, 5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=-\frac{1}{34}\left(x-12\right)[/tex]
Add 5 to both sides
[tex]y-5+5=-\frac{1}{34}\left(x-12\right)+5[/tex]
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]
Therefore, the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]V

A couple is starting a family and decides to have four children. Assume that the probability of having a boy or have a girl are equal. a) Find a probability model for the number of girls the couple has. b) Find the probability that the couple has at least one girl. c) What is the probability that the couple has exactly one boy or exactly one girl
Answer:
0.9375 ; 0.5
Step-by-step explanation:
Given that :
p = 0.5
Probability model for the Number of girls the couple has :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 0) = 4C0 * 0.5^0 * 0.5^4 = 0.0625
P(x = 1) = 4C1 * 0.5^1 * 0.5^3 = 0.25
P(x = 2) = 4C2 * 0.5^2 * 0.5^2 = 0.375
P(x = 3) = 4C3 * 0.5^3 * 0.5^1 = 0.25
P(x = 4) = 4C4 * 0.5^4 * 0.5^0 = 0.0625
Probability of having atleast one girl
Number of trials, n = 4
P(x ≥ 1) = p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)
Using the relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using calculator ;
P(x ≥ 1) = 0.9375
Probability of having exactly one boy or exactly one girl
1 boy 3 girls OR 1 girl 3 boys
P(x = 1)
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 1) = 4C1 * 0.5^1 * 0.5^3
P(x = 1) = 4 * 0.5 * 0.125
P(x = 1) = 0.25
The probability of having one girl, 3 boys and vice versa is 0. 25
Hence, Probability of having exactly one boy or exactly one girl
0.25 + 0.25 = 0.5

Find the unit rate. Ryan can mow 3/5 of the yard in 2
hours. How much of the yard can Ryan mow in one hour?
Answer:
3/10 of the yard in one hour
Step-by-step explanation:
[tex]3/5(1/2)=3/10[/tex]
Answer:
3/10 of the yard.
Step-by-step explanation:
What we know:
Ryan can mow 3/5 of a yard in 2 hours.
What we need to know:
How much of the yard Ryan can mow in 1 hour, so the unit rate.
How do we do this:
It's simple if you think about it.
Just divide 3/5 by 2 (or multiply by 1/2)
3/5 * 1/2
3/(5*2)
3/10 of the yard can be mowed in one hour.
Find the value of x in the triangle shown below
Answer:
x = 50
Step-by-step explanation:
Since the 2 legs are congruent, both 7, then the triangle is isosceles and the 2 base angles are congruent, then
x = [tex]\frac{180-80}{2}[/tex] = [tex]\frac{100}{2}[/tex] = 50
16 - x = -18
A. x = -18
B. x = -14
C. x = 14
D. x = 18
Answer:
None of these are correct? The correct answer is 34.
Step-by-step explanation:
Subtract 16 from each side, you get -x=-34
multiply each side by -1, you get x= 34
Answer:
18 or -18 depending if that is -x or x

solve a package of 17 sliced apples $2.21.How much would a package with 25 sliced apples cost at the same price per slice?????solve pleaseee middle school
Answer:
$3.25
Step-by-step explanation:
So,
If a package of 17 sliced apples is $2.21, lets find out the price per apple.
2.21 / 17 = 0.13
so, the price per apple is $0.13
Now, we find the price of a package with 25 sliced apples.
0.13 x 25 = 3.25
So, the price of a package with 25 sliced apples is $3.25

Nancy is trying to decide which cell phone plan would be the right one for her. She has
narrowed her choices down to two, Spirit and Horizon. Spirit (s) has a fixed fee of $20 and an
additional charge of 5 cents per minute. Horizon (h) has no fee and charges 15 cents per minute.
Write two equations that could be used to determine the total cost for each plan for 300 minutes?
A. s = 5x + 20
h=15x
B. s = 0.05x + 20
h = 0.15x
C. s = 15x
h = 5x + 20
D. s = 0.15x
h = 0.05x + 20

490 divided by 7 and i need to know the answer for that please
The result of 490 divided by 7 is 70.
To calculate 490 divided by 7, we can perform long division as follows:
70
__________
7 | 490
- 49 (7 times 7)
_______
0 (no remainder)
In the first step, we divide 7 into the first digit of 490, which is 4. The quotient is 0, and we bring down the next digit, which is 9.
Next, we divide 7 into 49. The quotient is 7, and there is no remainder.
Therefore, the answer to 490 divided by 7 is 70.

Please help me. Due tonight.
Answer:
The sum of the interior angles of any triangle are equal to 180
therefore in this triangle, m<a+m<c+m<b=180
we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,
9x-26+a=180
9x+a=206
a=206-9x
(206-9x)+(2x-12)+(4x+43)=180
combine like terms
-3x+237=180
-3x=-57
x=19
if x=19 then we can substitue it in for c
4x+43=c
4(19)+43=c
c=119

The midpoint of AB is M(-4,2). If the coordinates of A are (-6,5), what are the
coordinates of B?
Answer:
(-2,-1)
Step-by-step explanation:
Midpoints are found when you do ([x(subscript A) + x(subscript B)]/2, [y(subscript A) + y(subscript B)]. Therefore your equation (for x of B) should look like this:
-4 = ([-6+x]/2)
After you solve for x, you should have gotten -2 for x.
Then you do the same for y:
2 = ([5+y]/2)
You should get -1. Your final answer should be (-2, -1)

Jim works in real estate sales. His annual salary is
$20,000 plus 2.5% of his home sales. What was the total
value of all homes he sold if his annual pay for the year
was $120,000?
Helppppp
Answer:
4,000,000
Step-by-step explanation:
We start by subtracting his salary (20k) from his annual income. That means he got 100,000 from selling homes.
So, what is 100,000 2.5% of?
I used the equation:
100,000 = .025x
with x being the value of all the homes.
Just divide and conquer, and you end up with a final answer of 4 Million
