Step-by-step explanation:

h represents the number of houses. How i know this:

(1) the question states that each house costs $0.75. So 0.75h means 0.75 times a number of houses.

(2) h is used because houses starts with h. Also, h can't represent bikes because the "bikes" only appears in 1 number and doesn't have anything per bike. It only appears once.

15 represents the initial price of bike rentals.

- It says in the question, "Cycle City charges an initial price of $15 plus $0.75 per house for bike rentals". All of the information related to what 15 stands for is underlined. "Initial price" means a 1 time price that doesn't repeat. the 0.75 repeats based on how many houses you get.

0.75h represents the total cost for any number of houses.

(1) The question says "$0.75 per house" which means that each house costs 0.75. The h next to the 0.75 only means a number of houses. Whenever you see "something per something", expect the first letter of the 2nd word to be placed after the number.

If it doesn't make sense, let's say that h=1. In other words, we are buying 1 house. 0.75h means 0.75xh, so 0.75x1= 0.75. It's true. 1 house costs 0.75. You can also do 0.75x2, 0.75x3, and so on.

I hope i could help :)))

Answer:

Step-by-step explanation:

h= number of houses

0.75= cost per house

15= the initial price (price first paid)

No Solutions

Step-by-step explanation:

Hello!

We can approach this system using the Elimination method. Since the coefficients of the the x terms are the same, we should vertically subtract the two equations.

Since 0 does not equal to -11, there are no solutions to the system.

We can also look at this graphically. The two lines have the same slope but different y-intercepts, meaning that they would be parallel lines with no intersection. If there is no intersection, there are no solutions.

Answer:

Divide by -2

Step-by-step explanation:

Since we need to isolate h, we need to do the opposite operation that -2 is doing to h. In this case, -2 is being multiplied by h, and the opposite operation to multiplication is division.

This means that we need to divide both sides by -2.

Firstly, brainly allows 1 question per question. So do not try this again.

Lets make the fractions all like terms.

242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.

1. 51  1/4.

2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.

3. 36/5=72/10.      72/10 - 37/10 = 35/10. As a mixed it is 3 1/2

4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.

70/6 - 51/6 = 19/6. 3 1/6.

Answer: 4 yards

Step-by-step explanation: The formula for the volume of a cylinder is Pi * Radius squared * height.

If the end result is 256pi, and the height is 16, then the radius must be 4, because 4^2 = 16, and 16*16 = 256, and 256*pi = 256pi.

Please mark as brainliest if this was helpful.

Answer:

r = 4yd (Answer A)

Step-by-step explanation:

The volume of a cylinder of radius r and height h is V = πr²h, and the applicable V value here is 256π yd³.  We divide this by 16 yd to find the area of the base:  16π yd².

The base is a circle of radius r, which is to be determined:

πr² = 16π yd²

This reduces to r² = 16 yd², and so r = 4yd (Answer A)

Stepheet-by-step explanation:

Answer: -15.36, -1.44, 0.85, 4

Step-by-step explanation:

#1: -4.8x3.2= -15.36

#2: 2 1/4+ -1 2/5

2 1/4= 2.25

-1 2/5= -1.4

2.25+-1.4

*Whenever you have a +- something, it always becomes -

2.25 - 1.4= 0.85

#3: 4.32÷-3= -1.44

#4: -2 3/5 - -12/5

2 3/5= 2.6

-1 2/5= -1.4

2.6 - -1.4

*Whenever you have 2 minuses like - -, it always becomes a +.

So 2.6 - -1.4 becomes 2.6+1.4

2.6+1.4= 4

Okay so the numbers we have are:

-15.36, 0.85, -1.44, 4

The least number is the one farthest away from 0. This number would be -15.36, because, here's a rule to remember:

The "bigger" the negative number looks, the smaller it actualy is beacuse it is farther away from 0. For example, -29 is smaller than -1 even though it looks bigger because -29 is farther from 0. If it were positive numbers, 29 would definitely be greater though.So -15.36 is the smallest or the least.

Next, you see that -1.44 is the next in line because its the only remaining negative number and it has to be smaller than the others, which are positive.

3rd of all, i know that 0.85 comes next on the list because it is smaller than 4. It is still above 0, making it positive.

Finally, 4 is the greatest. It's bigger than 0.85, which obviously is less than 1.  Now here's the list of numbers from least--> greatest:

-15.36, -1.44, 0.85, 4

Now all you have to do is put these numbers into the boxes in order. If it doesn't make sense, try putting the first 2 numbers into the first 2 boxes. By doing this you get -15.36<-1.44, which is a true statment. If you want to go further, put 0.85 in the 3rd bubble to get -1.44<0.85 which is also true. Finally, when you put 4 in the last bubble, you get 0.85<4, which is true. That's how i know my answer is correct.

Hope this helps :))

Answer: $638.40

Step-by-step explanation:

45% converted to a decimal is 0.45

0.45 of $1200 = 0.45* $1200 (of in this case means multiply)

0.45 * $1200= $440

Because they said 11% of remaining salary, we have to do:

$1200-$440=$760

Now 11% converted to a decimal is 0.11

5% converted to a decimal is 0.05

So 0.11+0.05

0.11+0.05= 0.16

Now 0.16 *$760=$121.60

Now we find the remaining amount so we subtract: $760-$121.60= $638.40

So our answer is $638.40 left

Answer:

x = 0 or x = 1

Step-by-step explanation:

Given equation:

[tex]\dfrac{x}{x-2}+\dfrac{x-1}{x+1}=-1[/tex]

Multiply the two denominators to get the same denominator:

Multiply the numerator of the first fraction by the denominator of the second fraction to get the new numerator of the first fraction.

Multiply the numerator of the second fraction by the denominator of the first fraction to get the new numerator of the second fraction.

[tex]\implies \dfrac{x(x+1)}{(x-2)(x+1)}+\dfrac{(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]

Add the numerators and keep the denominator so that there is now one fraction:

[tex]\implies \dfrac{x(x+1)+(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]

Simplify the numerator by expanding the brackets:

[tex]\implies \dfrac{x^2+x+x^2-3x+2}{(x-2)(x+1)}=-1[/tex]

[tex]\implies \dfrac{2x^2-2x+2}{(x-2)(x+1)}=-1[/tex]

Simplify the denominator by expanding the brackets:

[tex]\implies \dfrac{2x^2-2x+2}{x^2-x-2}=-1[/tex]

Multiply both sides by the denominator of the left side:

[tex]\implies 2x^2-2x+2=-1(x^2-x-2)[/tex]

Simplify and move everything to the left side:

[tex]\implies 2x^2-2x+2=-x^2+x+2[/tex]

[tex]\implies 3x^2-3x=0[/tex]

Factor:

[tex]\implies 3x(x-1)=0[/tex]

Therefore:

[tex]\implies 3x=0 \implies x=0[/tex]

[tex]\implies x-1=0 \implies x=1[/tex]

Therefore, x = 0 or x = 1

Answer:

Option B       1 : 3

Step-by-step explanation:

Volume formulas & definitions:

To solve this problem, we must remember the formulas for volume of each shape:

[tex]V_{cylinder}=\pi r^2h\\V_{cone}=\frac{1}{3} \pi r^2 h[/tex]  where r represents the radius of the circular part of the shape, and h represents the height of the shape (the plural of height is "heights", and the plural of radius is "radii")

So, when the question states that the shapes "have congruent heights and radii" it means that the height of both objects is the same, and the radius of both objects is the same.

Ratios

To find the ratio of the volume of the cone to the volume of the cylinder, we must setup the ratio.  Ratios can be setup as a fraction where the first quantity is the numerator (top of fraction), and the second quantity is the denominator (bottom of the fraction):

[tex]\dfrac{V_{cone}}{V_{cylinder}}=\dfrac{\frac{1}{3} \pi r^2 h} {\pi r^2 h}[/tex]

Since the pi, the "r", and the "h" are the same in both the numerator and denominator (and since there is only multiplication & division in the fraction) these common factors can cancel, and reduce the fraction to the following:

[tex]\dfrac{V_{cone}}{V_{cylinder}}=\dfrac{\frac{1}{3}} {1}[/tex]

Any number divided by 1 doesn't change, so one-third divided by 1 is still one-third.

[tex]\dfrac{V_{cone}}{V_{cylinder}}=\frac{1}{3}[/tex]

Other representations of ratios

Lastly, we must remember that a ratio an also be written with a colon symbol, where the numerator is written first, and the denominator is written second.

So, the ratio of the volume of the cone to the volume of the cylinder is:

1 : 3
