Answer:
k=2
Step-by-step explanation:
(3/5k)-5=7/10k
we multiple both sides by 10k to get only one k
10k(3/5k)-5 = 7
(30k/5k)-5 =7 now we add 5 to other side and simplify our k fraction
6k= 12 divide by 6
k=2

Step-by-step explanation:
Explain how you calculate the constant of variation.
Answer:Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
Step-by-step explanation:The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
When 40% of a number is added to the number, the result is 168.
What is the number?
Answer:
-100.8
Step-by-step explanation:
Answer:
120
Step-by-step explanation:
Let's call the number x. 40% of that number is 4/10x, or 0.4x
So x + 0.4x = 168
1.4x = 168
1.Divide each side by 1.4
x = 120
The number is 120
C.
tan(450)
Help please!
Answer:
The answer is 0
Step-by-step explanation:
A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).
y -(-8) = -6(x - 2)
y -(-8) = -6x + 12
y -(-8) + 8 = -6x + 12 + 8
y = -6x + 20

1.) An American tourist changed US $925 into Trinidad and Tobago currency at the exchange rate US $1.00= TT $ 4.25
a.) Calculate the amount of TT dollars he received.
b.) The tourist spent TT $ 1806.25 and changed the remaining TT dollars into American currency at the same exchange rate. Calculate the amount of US dollars he received.
2.) A bank gives two dollars and seventy-five cents in Eastern Caribbean currency (EC $2.75) for one United states dollar (US$ 1.00).
Given that 1% tax is charged on all foreign exchange transaction, calculate the amount, in E.C. currency, which a tourist receives in exchange for US $1200.00.
3.) Given that TT $1.00= EC $ 1.12
And TT $ 4.25= US $1.00
Convert (a.) TT $55.00 to EC $
(b.) EC $850.00 to US $
4.) a.) A tourist changed US $ 1200 to Trinidad and Tobago currency. Calculate the amount she received at the exchange rate US $1.00= TT $2.40
b.) Calculate the amount she would receive at the exchange rate US $1.00=TT $ 5.76
Step-by-step explanation:
1)a) 925×4.25=3931,25
b) 1806.25:4.25=425

One dollar can buy a bottle of mineral water two empty bottles can be exchanged for a bottle of mineral water question:how many bottles of mineral water can you drink at most with 20 dollars
Step-by-step explanation:
If one dollar can buy a bottle of mineral water, then;
$1 = 1 bottle
To determine the amount of mineral water you can drink with at most 20 dollars, we will say;
$20 = x bottle
Solving both equality postulate;
$1 = 1 bottle
$20 = x bottle
Cross multiply
1 * x = 20 * 1
x = 20
Hence about 20 bottles of mineral drink can be bought with at most 20 dollars
Answer: 39
Step-by-step explanation:
You exchange $20 for twenty bottles of mineral water.
[Drank: 20
Exchanged: 20/2=10]
[Drank: 20+10
Exchanged: 10/2=5]
[Drank: 20+10+5
Exchanged: 4/2=2]
[Drank: 20+10+5+2+1
Exchanged: 2/2=1]
Drank in total: 20+10+5+2+1+1
which is = 39

Find the measures of the exterior angles of the polygon.
Step-by-step explanation:
180 - 34 = 146
one angle is a right angle, angle across it is 146, 360 - 90 - 146 = 124
divide that by two to get the measures of the remaining two angles (62 degrees)
180 - 62 = x
118 = x

A. 35
B. 85
C. 50
D. 25
Answer: B
Step-by-step explanation:
Use the exterior angle theorem, which states that the exterior angle of a triangle is equal to the sum of the two remote interior angles.
In this case: 120-x= 10+x+60
Simplifying it by combining like terms: 120-x=70+x
Solving by isolating the variable: 50= 2x, x=25
Now use what we know, which is that angle A is 35 degrees, and angle B is 60, to find out that the correct answer is B, 85 degrees.

3-for-1 split. After the split, the price of one share was $39.24. What was the pre-split price per share?
======================================================
Explanation:
Let's say that the company is valued at $300 just as a simple example.
Also, let's say there are 100 shares each worth $3, so we have 100*3 = 300 as the total value of the company.
A 3-for-1 split means that for each share, it will get turned into 3 shares. So you turn in 1 share and in return you get 3 shares back. Or put another way, each share is ripped/cut into 3 equal pieces.
After doing this split, we would have 3*100 = 300 shares and each share would be now worth (1/3)*3 = 1 dollar. Note the new number of shares multiplied with the new value per share is still the same total valuation of $300. Doing a stock split, or a reverse stock split, will not change the value of the company. This is a good thing or else companies would simply do (reverse) splits all the time to increase their value however large they wanted without actually contributing anything to society.
------------------------
So quite simply, when we do a 3-for-1 split, we multiply the old price per share by 1/3 to get the new price per share.
Let
x = old price per share
y = new price per share
So x happens before the split and y is after the split.
For a 3-to-1 split, we can form this equation
y = (1/3)x
which solves to
x = 3y
when we multiply both sides by 3
We know that y = 39.24, which means,
x = 3y
x = 3*39.24
x = 117.72
The pre-split price per share was $117.72
------------------------
So in short, all we did was multiply the given number (39.24) by 3.

Susan and Jayne have part-time jobs selling tickets at the theater. This week, Jayne's paycheck was twice the amount of Susan's paycheck. They both were paid $7.50 an hour, and Jayne's paycheck was $60. How many hours did Susan work this week?
Answer: 4 hours
Step-by-step explanation:
So if Jayne worked twice the amount of susans paycheck, it would be 60/2..so 30 is how much Susan has in her paycheck
Then you would divide both amounts by 7.50 because that’s how much they earn in a hour
J = 60/7.50 = 8 hours
S = 30/7.50 = 4 hours
Susan worked 4 hours
