What is the value of y in the solution to this system of equations?
y=3-2x/2
4x-6y=36

Answer:

[tex]V=251.32\ ft^3[/tex]

Step-by-step explanation:

The radius of cylindrical pipe, r = 2 ft

Length of the pipe, h = 20 ft

We need to find the volume of the pipe. We know that the volume of the cylinder is given by :

[tex]V=\pi r^2 h\\\\V=\pi \times (2)^2\times 20\\\\=251.32\ ft^3[/tex]

So, the volume of the cylinder is [tex]251.32\ ft^3[/tex].

Answer:

33.3%

Step-by-step explanation:

To get the gain percent, first we need to calculate the unit selling price and cost of each cosmetics.

If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then one cosmetic will cost 360/12 = Rs. 30

Also if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40

Selling price = Rs. 40

Cost price = Rs. 30

% gain = SP-CP/CP * 100%

% gain = 40-30/30 * 100

% gain = 10/30 * 100

% gain = 100/3

% gain = 33.3%

Hence the percentage gain is 33.3%

D. 7 intervals of 500 feet

Step-by-step explanation:

Got it right

Jamie used 5 intervals of 1000 feet as per the given data. The correct option is b.

A tally chart is a straightforward method of recording and counting frequencies. Each occurrence is represented by a tally mark, and every fifth tally is drawn diagonally to form a five-pointed star.

The first interval has a frequency of 7, which corresponds to the first 7 data points in the list:

1010

1470

1600

2000

2800

1053

1495

The last interval has a frequency of 2, which corresponds to the last 2 data points in the list:

2310

4260

Since there are 25 data points in total, and the first 7 and last 2 have been accounted for, that leaves 16 data points for the remaining intervals.

If Jamie used 1000-foot intervals, each interval would cover a 1000-foot range. The remaining data points range from 1200 to 4200 feet, so they are divided into 1000-2000, 2000-3000, and 3000-4000 foot intervals.

If Jamie used 500-foot intervals, each interval would cover a 500-foot range.

Thus, because the remaining data points range from 1200 to 4200 feet, they are divided into 1000-1499, 1500-1999, 2000-2499, 2500-2999, 3000-3499, 3500-3999, and 4000-4499 foot intervals.

Step-by-step explanation:

Answer:

[tex]\frac{4}{8}[/tex] = [tex]\frac{x-2}{x+3}[/tex] ( set the two triangles proportional to each other)

4(x+3)= 8(x-2) (Do the distributive property)

Answer:

Subtract 8.5

Step-by-step explanation:

To solve the equation, y has to be isolated (only y will be on one side of the equation)

To do this, we have to get rid of the 8.5, so it has to be subtracted from both sides.

So, the correct answer is subtract 8.5

Subtract 8.5 from both sides to solve equation.

We have the following equation -

y + 8.5 = 17.2

y + 8.5 - 8.5 = 17.2 - 8.5

y = 8.7

Therefore, Subtract 8.5 from both sides to solve equation.

SRQ = 66 degrees

Step-by-step explanation:

QRT = 33 degrees

A bisector bisects angles evenly, which means that SRTis also 33 degrees. ADD these two together you get 66 degrees for this angle.

Answer:

<SRQ = 66

Step-by-step explanation:

bisect means to "cut" in half so the line pretty much separates half and half

Step-by-step explanation:

Given

Dogs : Cats = 2 : 3

Required

Determine the possible number of dogs and cats at the store

The question requires options; since there are none, I'll answer on a general terms.

We have the dog to cat ratio to be:

Dogs : Cats = 2 : 3

Multiply ratio by any number (say 7)

Dogs : Cats = 2 * 7 : 3 * 7

Dogs : Cats = 14 : 21

This means that if there are 14 dogs, then there are 21 cats.

Multiply the ratio by another number (say 4)

Dogs : Cats = 2 * 4 : 3 * 4

Dogs : Cats = 8 : 12

This implies:

8 dogs and 12 cats

In conclusion, the number of dogs, when divided by the number of cats must equal ⅔.

Answer:

The equation of the line is:

Step-by-step explanation:

Given the points

Finding the slope between the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-5,\:8\right),\:\left(x_2,\:y_2\right)=\left(-1,\:9\right)[/tex]

[tex]m=\frac{9-8}{-1-\left(-5\right)}[/tex]

[tex]m=\frac{1}{4}[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1/4 and the point (-5, 8)

[tex]y-8=\frac{1}{4}\left(x-\left(-5\right)\right)[/tex]

[tex]y-8=\frac{1}{4}\left(x+5\right)[/tex]

Add 8 to both sides

[tex]y-8+8=\frac{1}{4}\left(x+5\right)+8[/tex]

[tex]y=\frac{1}{4}x+\frac{37}{4}[/tex]
