Electric guitar kits originally cost d dollars online. You buy the kits on sale for 50% of the original price, plus a shipping fee of $4.50 per kit.
After painting and assembly, you sell each guitar online for (1.5d + 4.5) dollars. Find your profit on each guitar sold
Answer:
your profit is Double the price that you bought the kits
Step-by-step explanation:
x= cost of kit
you buy it x/2
x/2 + 4.5 .... (1)
x + x/2 +4.5 .... (2)
let x = 40
40/2 + 4.5 = 24.5
40 + 40/2 + 4.5 = 64.5
64.5 - 24.5 = 40
so
you buy it in x/2 = 40/2 = 20
and sell it in x = 40
40/20 = 2
your profit is Double the price that you bought the kits
The profit is Double the price that you bought the kits.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given that the cost of the kits on sale for 50% of the original price, plus a shipping fee of $4.50 per kit.
Let x be the cost of kit.
Therefore,
x/2 + 4.5 .... (1)
x + x/2 +4.5 .... (2)
let x = 40
40/2 + 4.5 = 24.5
40 + 40/2 + 4.5 = 64.5
64.5 - 24.5 = 40
Therefore, buy it in x/2 = 40/2 = 20
and sell it in x = 40
40/20 = 2
Hence, the profit is Double the price that you bought the kits.

Determine the value of the missing digits
Answer:
M = 6
N= 7
Step-by-step explanation:
M + 7 = 3
M= 6
6 + 7 = 13, so we get 3 and carry 1
Now 1 + 4 + N = 12
1 + 4 + 7 = 12
So N = 7
Therefore,

In ΔABC, the measure of ∠C=90°, BA = 41, CB = 40, and AC = 9. What ratio represents the cosine of ∠B?
Answer:
40/41
Step-by-step explanation:
From the given diagram;
BA is the hypotenuse = 41
AC is the opposite = 9
CB is the adjacent = 40
Cos<B = adjaccent/hyp
Cos<B = CB/BA
Cos<B = 40/41
Hence the required ratio is 40/41

Step-by-step explanation:
I took all of the numbers and added them the subtracted 1 because you don't wanna include the basketball
The probability of not selecting a basketball from the bag is 18/19, or approximately 0.9474 (rounded to four decimal places).
Here, we have,
To find the probability of not selecting a basketball from the bag, we need to calculate the ratio of the number of items that are not basketballs to the total number of items in the bag.
Let's calculate it step by step:
Total number of items in the bag = 8 (tennis balls) + 2 (volleyballs) + 1 (basketball) + 3 (baseballs) + 5 (footballs) = 19.
Number of items that are not basketballs = 8 (tennis balls) + 2 (volleyballs) + 3 (baseballs) + 5 (footballs) = 18.
Therefore, the probability of not selecting a basketball is:
Number of items that are not basketballs / Total number of items in the bag = 18 / 19.
Hence, the probability of not selecting a basketball from the bag is 18/19, or approximately 0.9474 (rounded to four decimal places).

What is the slope?
m= 1/2
m=2/1
m= -1/2
m= -2/1
Answer:
m = 2/1
Step-by-step explanation:
Slope is rise over run
Looking at the graph we know the slope is positive since it goes up from left to right
We have a point at (2,0)
We have another point at (3,2)
m = (y2-y1)/(x2-x1)
= (2-0)/(3-2)
= 2/1
Kawai requires a loan of $33,000 to buy a used sport utility vehicle. His banks offers financing at 6.75% compounded monthly, for a term of 6 years, payable monthly. What is the total cost of this loan?
Answer:
$49,126.87
Step-by-step explanation:
Given data
Principal= $33,000
rate= 6.75%
Time= 6 years
First, convert R as a percent to r as a decimal
r = R/100
r = 6.65/100
r = 0.0665 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 33,000.00(1 + 0.0665/12)^(12)(6)
A = 33,000.00(1 + 0.005541667)^(72)
A = $49,126.87
Hence the final amount is $49,126.87

Help please thank you I have 1 more question-after this sorry for all the questions
Answer:
A - 6 units from the y axis. B - 5 units form the x axis. C - 8 units from T to V.
Step-by-step explanation:
So lets go over each question.
A asks for how many units point W is from the y axis. The y axis is the vertical line that goes up and down in the middle of the graph. This line is at x=0.
So we can think of the units between W and the y axis as the distance between W's x coordinates and 0.
In this case, we can see W's x coordinate is at 6.
So this means that W is 6 units from the y axis.
Next we have the distance between the x axis and point U.
The x axis is the line that goes left to right, and is at y=0.
We need to look at the y coordinate of U to find the difference between y=0 and U.
We can see that U is at y=5 on the graph.
So U is 5 units from the x axis.
The last question is the distance between point V and T.
We can see that the x coordinate for both points is x=2.
However, their y coordinates are different.
To find the difference, subtract the y coordinate of one point from the other.
In this case, the y coordinate of V is 5. The y coordinate of T is -3.
So lets see:
v-t=difference of y.
Plug in the values:
5--3
And since the negative sign and the minus sign cancel out:
5+3
=
8
So the difference in y is 8!
