A craft store buys 50 yards of satin ribbon for $13.50. The store
sells the ribbon by the foot. A customer can purchase 5 feet of
ribbon for $0.80. How much profit does the craft store earn if
they sell 45 yards of the ribbon and scraps the rest?
Answer:
$8.10 in profit
Step-by-step explanation:
First convert from yards to feet. 50 yards is equal to 150 feet. To find the unit price for how much they bought it for divide $13.50 / 150 to find that they bought the satin for 9 cents a foot.
Next find how much they sold it for. To find this divide $0.80 / 5 to find that they sold the satin for 16 cents a foot.
To find the profit for 45 yards, convert 45 yards to feet which is 135 feet. Then multiply this by the unit price for sales, 135 * $0.16 to get $21.60
To find the profit subtract the amount they spent on the fabric by the amount they made.
21.60-13.50 = $8.10
Determine the value of each variable.
Answer:
a=9, b=45, c=31.5, d=18, f=27
Step-by-step explanation:
To find the value of a, you can take 72-54=18 and do 18/2=9
a=9
To find the value of b, you can multiply the three a's. 27 is the product of the 3 a's. Next, you will do 72-27 to find the value of b
b=45
To find the value of c, you can take 9 and subtract it from 72, or in other words: 72-9=63. You will then divide 63/2 to find the value of c
c=31.5
To find the value of d, you can multiply (9*4)=36. You can then take 72-36 and get 36. To find the value of d, you will then divide 36/2.
d=18
To find F, you are given a clue that 1 a and 1 d together=f.
9+18=f
f=27
Answer:
a=9
b=36
c=45
d=31.5

An analysis of variance is used to evaluate the mean differences for a research study comparing four treatments with a separate sample of n = 8 in each treatment. If the data produce an F-ratio of F = 4.60, which of the following is the correct statistical decision? a. Reject the null hypothesis with α = .05 but not with α = .01 b. Reject the null hypothesis with either α = .05 or α = .01 c. Fail to reject the null hypothesis with either α = .05 or α = .01 d. There is not enough information to make a statistical decision
Considering the p-value of the f-ratio, it is found that the correct option is given by:
a. Reject the null hypothesis with α = .05 but not with α = .01.
What is the relation between the p-value and the test hypothesis?Depends on if the p-value is less or more than the significance level:
If it is more, the null hypothesis is not rejected.If it is less, it is rejected.In this problem, the test statistic is of F = 4.60, with 4 x 7 = 28 df between treatments and 7 df in a single treatment, hence, using a calculator, the p-value is of 0.0218, which is less than 0.05 but more than 0.01, meaning that option A is correct.

There were 30 cookies in a basket. Haley ate 10% of the cookies. Erin ate 1 6 of the cookies. Hannah ate 1 5 of the cookies. Madison ate 30% of the cookies. How many cookies are left in the basket?
The number of cookies left in the basket after everyone has eaten out of the cookies is 7.
How many cookies are left?The first step is to convert the fractions to percentages.
1/6 x 1000 = 16.67%
1/5 x 100 = 20%
Now determine the sum of the percentages of the cookies eaten : 10% + 30% + 16.67 + 20% = 76.67%
Determine the percentage of cookies left = 100 - 76.67 = 23.33%

Benson has a bankruptcy on his credit report, so he pays higher interest rates on his current loans. he calculates that the extra money he pays in additional interest each year, if invested at the rate of 2% for one year, could earn him simple interest totaling $180. how much does benson pay in additional interest each month? a. $360 b. $750 c. $900 d. $1,000 please select the best answer from the choices provided. a b c d
The additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year, option (b) is correct.
What is simple interest?It is defined as the interest on the based on the principal amount, it does not include the compounded amount. The interest calculate on the initial amount or borrowed amount.
We know the formula for the simple interest is given by:
I = PRT
Where I is the simple interest.
P is the principal amount
R is the rate of interest
We have in the question:
I = $180
R = 2% = 0.02
T = 1 year
Put the above values in the formula, we get:
180 = P(0.02)(1)
P = $9000
The additional interest Benson pay each month is:
= 9000/12
= $750
Thus, the additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year option (b) is correct.

Consider the line - 3x +9y = 5.
Find the equation of the line that is perpendicular to this line and passes through the point (5, -1).
Find the equation of the line that is parallel to this line and passes through the point (5, -1).
Answer:
[tex]\textsf{Perpendicular to given line}:y=-3x+14[/tex]
[tex]\textsf{Parallel to given line}: y=\dfrac13x-\dfrac83[/tex]
Step-by-step explanation:
Rewrite the given equation to make y the subject:
[tex]\begin{aligned}-3x+9y &=5 \\ \implies 9y &=3x+5 \\ \implies y &=\dfrac13x+\dfrac59\end{aligned}[/tex]
Therefore, the slope of the given equation is [tex]\frac13[/tex].
If two lines are perpendicular to each other, the product of their slopes will be -1. Therefore, the slope (m) of the line that is perpendicular to the given line is:
[tex]\begin{aligned}m \times \dfrac13 & =-1\\ \implies m & =-3\end{aligned}[/tex]
To find the equation of the line, substitute the found slope (-3) and the point (5, -1) into the point-slope form of a linear equation:
[tex]\begin{aligned}y-y_1 & =m(x-x_1)\\ \implies y-(-1) &=-3(x-5) \\ y+1 & =-3x+15 \\ y &=-3x+14\end{aligned}[/tex]
If two lines are parallel to each other, their slopes will be the same. Therefore, the slope (m) of the line that is parallel to the given line is [tex]\frac13[/tex]
To find the equation of the line, substitute the slope ([tex]\frac13[/tex]) and the point (5, -1) into the point-slope form of a linear equation:
[tex]\begin{aligned}y-y_1 & =m(x-x_1)\\\\ \implies y-(-1) &=\dfrac13(x-5) \\\\ y+1 & =\dfrac13x-\dfrac53 \\\\ y &=\dfrac13x-\dfrac83\end{aligned}[/tex]
Slope =m=1/3
Note that perpendicular lines have slopes negative reciprocal to each other .
Slope of the perpendicular line=-3Equation in point slope form
y+1=-3(x-5)y+1=-3x+15y=-3x+14And

The two triangles shown are congruent.
Find the value of x
Answer:
x = 11
Step-by-step explanation:
right triangle ABC
using Pythagoras' identity
BC² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )
BC = [tex]\sqrt{625}[/tex] = 25
Since the triangles are congruent then corresponding sides are congruent.
ST = BC , that is
3x - 8 = 25 ( add 8 to both sides )
3x = 33 ( divide both sides by 3 )
x = 11
5. How long is the diagona of a 12 ft-by-16 ft rectangular garden?
A. 6 ft
B. 14 ft
C. 18 ft
D. 20 ft
Answer:
The correct answer is option D, 20ft
Step-by-step explanation:
After drawing the picture below, you can just use pythagorean theorem to solve for the diagonal, or the hypotenuse in this case;
(Length)² + (Width)² = (Diagonal)²
(16)² + (12)² = (Diagonal)²
256 + 144 = (Diagonal)²
400 = (Diagonal)²
[tex]\sqrt{400}[/tex] = [tex]\sqrt{Diagonal^{2} }[/tex]
20 = Diagonal
Hope this helps!
Answer:
D. 20 ft
Step-by-step explanation:
Use pythagorus! We can imagine the rectangle is split into 2 equal triangles, one side of the triangle being 12, and the width being 16.
Pythagorus theorum is used to calculate the hypotenuse (long side) of a right-angled triangle. This is the formula:
[tex]\sf{a^{2}+b^{2} = c^{2} }[/tex]
So, we do 12^2 (squared) + 16^2 =
144 + 256 = 400
Now, we have to find the square root of 400, which is equal to
20
So our answer is 20ft
