Does the equation represent a direct variation? If so, find the constant of variation.
4x -5y = 0
a. yes; k = -5 b. no c. yes; k = 4/5 d. yes; k = - 4
Answer:
C
Step-by-step explanation:
4x-5y=0
5y=4x
y=4x/5, or rather y = (4/5)*x
k thus equals 4/5, and that is your constant of variation.
Answers: Yes, direct variation, k=4/5

A piece of duct measures 48 inches. When pieces are fitted together, 1 72 inches is lost connecting each successive length of duct. On the job 7 and 12 pieces of ducting are used. What, in inches is the total length of the finished duct?
Answer:
A piece of duct measures 48 inches.
In each connection, we lost 1.72 inches (it also could be 1/2 inches, but i will go with the other option)
Then:
If we have 7 pieces of duct connected we have 5 connections (the ones in the extremes are not connected between them)
So here we have 7 times 48 inches for the pieces, minus 5 times 1.72 inches for the connections, the length is:
L = 7*48in - 5*1.72in = 327.4 inches.
for the 12 pieces duct, we have 12 pieces and 10 connections, so the length is:
L = 12*48in - 10*1.72in = 558.8 in
Now, if we want to make only one duct with those two, then we must add their lengths, but if we connect them, we also need to subtract the 1.72in of the new connection:
L = 558.8 in + 327.4 in - 1.72in = 884.48 in

The perimeter of a square is 3x-4 units. If the area of the square is 25 square units, what is the value of x?
Answer:3
Step-by-step explanation: 3(3)-4 =5
Area now is 5•5 equivalent to 25 :)
The value of x is 8.
Given that, the perimeter of a square is 3x-4 units, and the area of the square is 25 sq units, we need to find the value of x,
We know that the perimeter of the square = 4(sides)
Therefore,
4(sides) = 3x-4
sides = 3x-4 / 4
Now, the area = side²
= (3x-4 / 4)²
therefore,
(3x-4 / 4)² = 25
Taking the roots,
3x-4 / 4 = 5
3x-4 = 20
3x = 24
x = 8

pierre, an art dealer, earns 25% commission of the dollar value of the art pieces that he sells at the bizzell Gallery. Pierre earns $10,800 this month. what is the total dollar value of the art that he sells?
Answer:
$43,200
Step-by-step explanation:
25% is 1/4 of the total dollar value, to find the answer we need to multiply 10,800 by 4 (it is 1/4, and the answer will be equivalent to the 4/4)
10,800 * 4 = 43,200
The total dollar value of the art that he sells is 43200 dollars.
What is percentage ?Percentage is the value per hundredth.We can also convert percentages into decimals by dividing he percentage value by 100.
According to the given question Pierre, an art dealer, earns 25% commission of the dollar value of the art pieces that he sells at the Bizzell Gallery. Pierre earns $10,800.
∴ 25% of the total value is 10800 dollars.
Assuming total value to be x dollars.
So, (25/100)x = 10800
(1/4)x = 10800
x = 10800 × 4
x = 43200 dollars.

Answer: 3: 42.49
Step-by-step explanation:
_________________________________
Hey!!
Solution,
Marked price (MP)=$ 49.99
Discount percent=15%
Sale price (SP)=?
Now,
Discount amount=discount% of MP
=15% of 49.99
=$7.4985
Again,
Sale price=MP- Discount
=49.99-7.4985
=$ 42.49
So the sale price is $42.49
Hope it helps..

If two right triangles each have a 30° angle, then the
triangles must be
a equilateral
b.similar
C. obtuse
D. congruency
Answer:
b. Similar
Step-by-step explanation:
Although angles are congruent the triangles are not as sides need to be the same too. Both shapes have 90 degree and 30 degree and add up to 180 degree in each triangle. Therefore each shapes angles are congruent but we dont know there size or scale, so they are similar. if they are the same (shape and size)- in other words, if the lengths of the sides and the angles are the same. So they are similar.
Because the angles are congruent and sizes are not shown they must be similar.
They cannot be obtuse as no angle is larger than 90 degrees and to be obtuse it would have to be larger than 90 deg and lower than 180 deg.
They cannot be equilateral as that means it couldn't be 30 degree and a right angle as equilateral means same angle sizes within 'one' triangle or for every or each triangle; as we know all triangles that are equilateral are 60, 60, 60 degrees to add up to 180 degree and cannot be an equilateral for this reason too as we have right angle triangles and equilateral are not right angles due to being 60 degree angle measures.
They are not fully congruent as we do not know there side measures so they have to be similar.
Answer:
B
Step-by-step explanation:
Two triangles are similar when they share at least two angles and the only difference is size.

A jar of quarters and dimes contains $20.00. There are 110 coins in all. How many of each are there?
Answer:
There are 50 dimes and 110-50 = 60 quarters in the collection.
Step-by-step explanation:
Let D be the number of dimes.
Then the number of quarters is (110-D).
The "value equation" is
10D + 25*(110-D) = 2000.
Simplify and solve for D:
10D + 2750 - 25D = 2000,
-15D = 2000 - 2750,
-15D = -750,
D = %28-750%29%2F%28-15%29 = 50.

Answer
102
Step-by-step explanation:
X means 3 not times, lots of people mess that up sometimes. Anyways, do 8+3 which equals 11. 8+3=11. So next what you do is you do 11 + 16 which is 27,
equations:
8+3=11
11+16=27
21/1=27
27/4= 6.75
6 x 3= 27
27 + 72 + 3= 102
Then go back to the beginning and do 1/4. If this confuses let me fix it.
now divide it with 4. Look at the equations list. Okay now do 6.72/4x. MAKE SURE TO MULTIPLY DON'T DIVIDE! You multiply 6 and 4 then you add 72 and three! Then you should end up with 102! I hope this worked message me back if it did :)
