Answer:
The direct variation equation is y = 6x
Step-by-step explanation:
The direct variation equation is y = kx, where
k is the constant of variationTo find the value of k, use the initial values of x and y
∵ y = 5, y = 30
∵ y = k x
→ Substitute the values of x and y to find k
∵ x = 5 and y = 30
∴ 30 = k (5)
∴ 30 = 5k
→ Divide both sides by 5
∴ [tex]\frac{30}{5}=\frac{5k}{5}[/tex]
∴ 6 = k
→ Substitute it in the form of the equation
∴ y = 6x
The direct variation equation is y = 6x
6. You earn 8% commission on sales. What is the commission if the sales
were as follows. 4 items at $1200,7 items at $650; 7 items at $600, and 6
items at $450? (no commas)*
Answer:
The total commission is=$1300
Step-by-step explanation:
The commission rate is a fixed number that applies to all the sales made by a salesperson. In our problem, the fixed commission rate is 8%, and the sales were as follows:
4 items at $1200 for a total of $4800. The commission is:
8% of 4800 = 0.08*4800 = $384
7 items at $650 for a total of $4550. The commission is:
8% of 4550 = 0.08*4550 = $364
7 items at $600 for a total of $4200. The commission is:
8% of 4200 = 0.08*4200 = $336
6 items at $450 for a total of $2700. The commission is:
8% of 2700 = 0.08*2700 = $216
The total commission is: $384+$364+$336+$216=$1300
The total commission is=$1300
Choose the inequality that Caroline's hair is
7 inches long and grows about 1/5 inch each month. Trinity's hair is 10 inches long and
grows about 1/10 inch each month. How many months will it take for Caroline's hair to be
at least as long as Trinity's hair?*
Answer:
7 +1/5x ≥ 10 +1/10x . . . . . lower left picture of those shown here
Step-by-step explanation:
Caroline's hair length in inches can be expressed as ...
c = 7 + 1/5x . . . . after x months
Trinity's hair length in inches can be expressed as ...
t = 10 + 1/10x . . . . after x months
When Caroline's hair is at least as long as Trinity's, we have ...

Cal jogs from 10:28 AM until 11:15 AM. For about how long does Cal jog?
Answer:
47 minutes
Step-by-step explanation:
In elapsed time, it's better to make your problem more readable so it's easier to solve. Add 2 minutes into 10:28 so it turns into 10:30. Then add 30 minutes so it turns into 11:00 AM. Finally, add 15 minutes so it turns into the 11:15 you were looking for. When you combine the minutes allotted (2, 30, and 15) you get 47 minutes.

The range is the vertical extent of the graph.
Left Graph
We assume the curve is intended to touch, not cross, the line y=4, so the range is ...
range: (-∞, 4]

Two functions are shown below
f(x)=6x+3
g(x)=3x-2
What is the product of f(3) and g(-4)
Answer:
-294
Step-by-step explanation:
f(3) = 6(3) + 3
f(3) = 18 + 3
f(3) = 21
g(-4) = 3(-4) - 2
g(-4) = -12 - 2
g(-4) = -14
f(3) * g(-4) = 21 * -14 = -294
Hope this helps!
Answer:
a. -294
Step-by-step explanation:
f(x)=6x+3
f(3)=6(3)+3
f(3)= 18 +3
f(3)= 21
g(x)=3x-2
g(-4)=3(-4)-2
g(-4)=-12-2
g(-4)=-14
21 x -14 = -294

A wall measures 2 meters 30 centimeters in width.
What is the width of the wall in millimeters?
A:0.0023 mm
B:0.23 mm
C:2.3 mm
D:2,300 mm
Answer:
The answer is D
Step-by-step explanation:
1 meter = 1,000 millimeters
1 centimeter = 10 millimeters
2 meters = 2,000 millimeters
30 centimeters = 300
2,000+30=2,300
Answer: D. 2,300
Step-by-step explanation:
There is 1000 millimeters in a meter which gets you 2000 plus the 30 centimeters. 30 centimeters is equal to 300 millimeters because for every centimeter its 10 millimeters. Add the 2000 to the 300 and get 2300 millimeters.
Karen invests $2,400 into an account with a 6.8% interest that is compounded annually. How much money will she have in this account if she keeps it for 8 years? Round your answer to the nearest cent. Do NOT round until you have calculated the final answer.
Answer:
The answer is 4062.39
Step-by-step explanation:
A=$2,400(1+0.0681)1(8). Simplify using the order of operations: A=$2,400(1.068)8=$2,400(1.692661131)≈$4,062.39.
The amount of money after 8 years will be $4062.38.
What is compound interest?In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.
Given that Karen invests $2,400 into an account with a 6.8% interest that is compounded annually. The amount after 8 years will be calculated as below:-
Amount = P [ 1 + ( r / n )]^(nt)
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Amount = 2400 [ 1 + ( 0.068 / 1 ) ] ⁸
Amount = 2400 [1.068 ) ] ⁸
Amount = 4062.38
Therefore, the amount of money after 8 years will be $4062.38.
