What’s the fraction of the T-shirts

Check step-by-step explanation.

In order to form the table, we must take several values of x (any values you want to evaluate) and find it's correspondent y value. This is how you  do it:

[tex]y=3x+12[/tex]

[tex]x=0, \\y=3(0)+12\\y=12[/tex]

As you may notice, we are just substituting the x value for the x variable into the equation and calculating y. Do this with several values and form a table (check attached image 1).

[tex]x=1, \\y=3(1)+12\\y=15[/tex]

[tex]x=2, \\y=3(2)+12\\y=18[/tex]

Using the calculated points, draw them in the cartesian plane. Remember that "x" means how many spaces you move horizontally, and "y" means vertical spaces.

Check attached image 2.

Let's take point (2, 18) as an example. This point is generated when you substitute the x value of 2, meaning 2 hotdogs and the souvenir hat. Then, the functions gives a result of 18, which would be the cost of those 2 hotdogs in addition to the souvenir hat. Point (0, 12), on the other hand, means that you didn't buy any hotdogs but you still have to pay $12 for the souvenir hat.

Check the picture below, so the ellipse looks more or less like so

[tex]\textit{ellipse, horizontal major axis} \\\\ \cfrac{(x- h)^2}{ a^2}+\cfrac{(y- k)^2}{ b^2}=1 \qquad \begin{cases} center\ ( h, k)\\ vertices\ ( h\pm a, k)\\ c=\textit{distance from}\\ \qquad \textit{center to foci}\\ \qquad \sqrt{ a ^2- b ^2} \end{cases} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\begin{cases} h=-4\\ k=10\\ a=8 \end{cases}\implies \cfrac{(x- (-4))^2}{ 8^2}+\cfrac{(y- 10)^2}{ b^2}=1\implies \cfrac{(x+4)^2}{ 8^2}+\cfrac{(y- 10)^2}{ b^2}=1 \\\\\\ \stackrel{\textit{we know that c = 6}}{6=\sqrt{8^2 - b^2}}\implies 6^2=8^2-b^2\implies b^2=8^2-6^2\implies \underline{b^2=28} \\\\\\ \cfrac{(x+4)^2}{ 8^2}+\cfrac{(y- 10)^2}{ b^2}=1\implies {\Large \begin{array}{llll} \cfrac{(x+4)^2}{ 64}+\cfrac{(y- 10)^2}{ 28}=1 \end{array}}[/tex]

Answer:

  (c)  50 units²

Step-by-step explanation:

You want to know the area of the rectangle with vertices (-5, 5), (-1, 7), (4, -3), and (0, -5).

The distance formula can be used to find the lengths of the sides. That formula is ...

  d = √((x2 -x1)² +(y2 -y1)²)

The distance between the first two points is ...

  d = √((-1 -(-5))² +(7 -5)²) = √(4² +2²) = √20

The distance between the next two points is ...

  d = √((4 -(-1))² +(-3 -7)²) = √(5² +(-10)²) = √125

The area is the product of two adjacent side lengths:

  A = LW

  A = (√125)·(√20) = √(125·20) = √2500 = 50 . . . . square units

The area of the rectangle is 50 units².

Answer: (3x^2)(y^3√y)

Step-by-step explanation:

1. To simplify the radical

> break the radicand (the number under the radical sign) into a product (the result of two numbers being multiplied together) of known factors.

2. Assume all numbers are real.

Answer:you have 2 lines that cross.

the left angle formed is equal to 3x + 8

the right angle formed is equal to 5x - 20.

the bottom angle formed is equal to 5x + 4y

since the lines are crossed, the opposite angles to each other are equal.

this means that:

3x + 8 = 5x - 20

solve for x to get x = 14 degrees.

the angle on the left side will be equal to 3(14) + 8 = 50 degrees.

the angle on the right side will be equal to 5(14) - 20 = 50 degrees.

this is at it should be since the angles are equal to each other.

since the sum of the 4 angles formed is equal to 360 degrees, the sum of the remaining 2 angles is equal to 260 degrees.

since those 2 angles are equal, then each one must be equal to 130 degrees.

one of those angles is equal to 5x + 4y.

you get 5x + 4y = 130

since x was already found to be 14, replace x with 14 to get:

5(14) + 4y = 130

solve for y to get y = (130 - 5(14)) / 4 which is equal to 15 degrees.

when x = 14 and y = 15, 5x + 4y = 5(14) + 4(15) = 70 + 60 = 130 which confirms the value of 15 for y is good.

your answers are:

x = 14 degrees

y = 15 degrees

2 of the angles measure 50 degrees each.

2 of the angles measure 130 degrees each.

Answer:

y = 5x/6 + 3/2

Step-by-step explanation:

First, find the slope (m):

m=(y2-y1)/(x2-x1)

m=(9-4)/(9-3)

m=5/6

y=mx+b ==> slope-intercept form equation

y = 5x/6 + b==> substitute the value of the slope for m

9 = 5(9)/6 + b ==> substitute a point (x, y) or (9, 9) into the equation

9 = 45/6 + b ==> simplify

(9 = 45/6 + b)*6 ==> multiply the equation by 6 to remove denominators

54 = 45 + 6b ==> simplify

54 - 45 = 45 - 45 + 6b ==> solve for b

9 = 6b

9/6 = 6b/6

b = 3/2

y = 5x/6 + 3/2 ==> plug in b for the slop-intercept equation

Altogether, Abby and Annie have 2,400 coins, using the Lowest Common Multiple of 75 and 80.

The lowest common multiple (LCM) of two or more numbers is the common multiple shared by the numbers.

LCM of 75 and 80 can be obtained by multiplying common prime factors of 75 and 80, and then raising them to their respective highest power, i.e. 2^4 × 3^1 × 5^2, which gives 1200.

For instance, 1,200 can be divided by both 75 and 80 evenly without a remainder.  And there is no other number less than 2,000 that 75 and 80 can divide evenly without a remainder.

Abby's coins = 1,200

Annie's coins = 1,200

Total coins = 2,400

Abby's 80 coins will have 15 groups (1,200/80)

Annie's 75 coins will have 16 groups (1,200/75)

Thus, using the LCM of 80 and 75, the total number of coins held by Abby and Annie is 2,400.

Answer:

El otro extremo dista :

12.5 decímetros

Step-by-step explanation:

1 dm = 1 decímetro = 10 cm

1 m = 1 metros = 10 decímetros = 10 dm

3.5 metros = 3.5 * 10 = 35 decímetros

125 cm = 125/10 = 12.5 decímetros

Entonces:

35 dm - 12.5 dm = 22.5 dm

Step-by-step explanation:

Slope = (y2 - y1) / (x2 - x1)

Slope = 5/2

x1 = -6

y1 = y

x2 = 4

y2 = 8

5/2 = (8-y) / (4 - (-6))

5/2 = (8-y) / (4+6)

5/2 = (8-y) / 10

5 x 10 = 2 x (8-y)

50 = 16 - 2y

2y = 16 - 50

2y = -34

y = -17

The speed of the humming bird when converted to miles per minute is; 0.67 miles per minute

In scientific problems, sometimes, it is necessary to change units from one to another as specifically needed.

The procedure for unit conversion is;

1. Identify the unit you have.

2. Identify the unit you desire or require.

3. Identify appropriate unit conversion factor(s).

4. Cancel units and carry out the math calculations.

5. Evaluate the result.

We are given the speed as 40 miles per hour. Now, the unit of conversion factor from mph to miles per minute is;

1 mile per hour = 1/60 miles per minute

Thus;

40 miles per hour = 40 * 1/60 = 0.67 miles per minute

Answer:

36mins

Step-by-step explanation:

So, the time of travel to cover 5 1/5 miles at a speed of 8 2/3 mph is 36 minutes.

Answer:

a = 70 degrees

b = 20 degrees

c = 20 degrees

Step-by-step explanation:

First, we can find "c":

angleBCA = 90

angleBCA = angleBCD + c

90 = 70 + c

90 - 70 = c

20 = c

Knowing "c", we can find "a".

angleADC = 90

triangleADC = 180

triangleADC = angleADC + c + a

180 = 90 + 20 + a

180 = 110 + a

180 - 110 = a

70 = a

Knowing "a", we can find "b".

angle BCA = 90

triangleACB = 180

triangleACB = angleBCA + a + b

180 = 90 + 70 + b

180 = 160 + b

180 - 60 = b

20 = b

9 feet is the same as = 2.74 m

Given

1 ft≈ 0.305 m

To find out 9 feet is the same as how many meters:

To convert a foot measurement to a meter measurement, multiply the length by the conversion ratio.

Since one foot is equal to 0.3048 meters, you can use this simple formula to convert:

meters = feet × 0.3048

= 9 * 0.3048

= 2.7432 m

The length in meters is equal to the feet multiplied by 0.3048.

Hence the answer is the 9 feet is the same as meters = 2.74m.

The bottle of grapefruit juice at store A is $6.63 less than the store B.

According to the question,

We have the following information:

The equation y = 1.75x represents what Lamonte would pay in dollars and cents, y, for a bottles of grapefruit juice at store A.

Cost of 17 bottles of grapefruit juice at store B = $36.38

Now, we will find the cost of 17 bottles at store A.

y = 1.75*17

y = $29.75

Now, the difference in their price = 36.38-29.75

Difference = $6.63

Hence, the bottle of grapefruit juice at store A is $6.63 less than the store B.
