The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

Step-by-step explanation:

Please look at the picture below also as you read the answer!

1.

To find the cubic inches of pasta, first, let's find the diameter.

If the radius (always half of the diameter) is 3.2, then what's the diameter?

3.2+3.2=6.4

So, the diameter is 6.4 inches

2.

Find how much height is the pasta at

The container is 14 inches high, but the past is only filled till the top leaving 1.5 inches of space, what can we do to find out how much height is the pasta filled till?

14-1.5=12.5

So, the height till what the pasta is filled till is 12.5

3.

The formula for finding this...

V=BxH

V=Volume

B=Base

H=Height

4.

Applying the formula

BxH=?

Base = 6.4 inches

Height = 12.5 inches

6.4x12.5=?

64x125=8000

           =80.00

(after removing 2 zeros in the back, because the original number was having decimal)

So, hence, the volume of our awesome cylinder of pasta is 80 Cubic Inches!

Answer:

A) solution 2 is more acidic than solution 1

Step-by-step explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

The relationship is 2 because 6/3=2

Answer: 10

Step-by-step explanation: The answer is 10 because xy means x times y, and since x = 10 and y = -2, 10 times -2 equals -20. Now you have to divide that by --2 which is just 2. So -20/2 equals -10. -10's absolute value is 10. Thus the answer is 10.

Answer:

8 times more clay than the original cube

Step-by-step explanation:

There's no picture here so I'll say it variably. If the original cube has side length \(x\), then the amount of clay needed is \(x^3\) because the formula for volume of a cube is \(v=s^3\). Similarly, a cube with side lengths twice as long would have a side length of \(2x\). The volume of this new cube would be\((2x)^3=8x^3\), 8 times the volume of the original cube.

Step-by-step explanation:

Square Area

8-3 to get the right side of the square which equals 5. So the square is 5*6=30

Triangle Area

To get the area of a triangle the formula is a=b*h*1/2, so base is 3 and height is 3, we would do 3*3*1/2 which equals 4.5

but you have 2 triangles so multiply 4.5*2 and that's 9.

Answer:

See Below

Step-by-step explanation:

Take the the given information and compare to the question being asked

\(\frac{y}{x}\). So insert the x & y's of both equations (ima do y over x to make it easier)

\(\frac{14}{4} =\frac{y}{40}\)

divide 14/4

3.5 = \(\frac{y}{40}\)

then multiply both sides by 40 to isolate y

140 = y

Check by reinserting 140 and divide it by 40

Answer:

y= 140

Step-by-step explanation:

if they are directly proportional, that means when one increases/decreases the other does as well.

x increased by multiplying itself by ten. Like before, since they are both directly proportional that means that y is multiplied by 10.

14*10= 140, y=140
