D. 82

Answer:

[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

In which r is the radius.

Center (-12, – 7)

This means that [tex]x_0 = -12, y_0 = -7[/tex]. So

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - (-12))^2 + (y - (-7))^2 = r^2[/tex]

[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]

Passes through the point (-3,7).

This means that we use [tex]x = -3, y = 7[/tex] to find the radius squared. So

[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]

[tex](-3 + 12)^2 + (7 + 7)^2 = r^2[/tex]

[tex]81 + 196 = r^2[/tex]

[tex]r^2 = 277[/tex]

The equation of the circle is:

[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]

[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]

Answer:

The answer is n = 13

Step-by-step explanation:

1) Divide both sides by 3.

[tex] \frac{3}{24} = n - 5 [/tex]

2) Simplify 24/3 to 8.

[tex]8 = n - 5[/tex]

3) Add 5 to both sides.

[tex]8 + 5 = n[/tex]

4) Simplify 8 + 5 to 13.

[tex]13 = n[/tex]

5) Switch sides.

[tex]n = 13[/tex]

Therefor, the answer for this equation is n = 13.

Answer:

a) You have a 30% of not drawing yellow or green

b) You'd have a 46% of frawing a red or green bead

Step-by-step explanation:

Total beads: 42 + 28 + 12 + 18 = 100

Green beads + yellow beads = 28 + 42 = 70

100 - 70 = 30

30/100 = 0.3 or 30%

Red beads + green beads = 18 + 28 = 46

46/100 = 0.46 or 46%

Answer:

1. 30%

2.46%

Step-by-step explanation:

The probability of Kayla not drawing a yellow or a green bead is 30 %. The probability of Kayla drawing a red or a green bead is  46 %.

Answer:

101.9 degrees

General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

Let's define what we have:

Conner's morning temperature: 101.2 degrees

Conner's last night temperature: morning temperature + 0.7 degrees

We know that Conner's last night temperature is addition because it was higher (key word) than the morning temperature.

Therefore, we simply add the values together to get our answer:

101.2 + 0.7 = 101.9 degrees

Answer:

y = -1, x = -2

Step-by-step explanation:

First, multiply the top equation by 2 to make 3x become 6x:

6x - 8y = -4

Second, multiply the bottom equation by 3 to make -2x become -6x:

9y - 6x = 3

Add the two equations together, and you get:

y = -1

Plug in y as -1 into the first or second equation:

3x - 4(-1) = -2

OR

3(-1) - 2x = 1

x = -2

Answer:

y = 1

Step-by-step explanation:

-3y + 14 + y = 12

-3y + y + 14 = 12

-2y + 14 = 12

-2y + 14 - 14 = 12 - 14

-2y = -2

-2y/-2 = -2/-2

y = 1

Answer:

y=1

Step-by-step explanation:

Hey There!

So to solve this type of problem we use inverse operations

-3y+14+y=12

step 1 subtract 14 from each side

14-14

12-14=-2

now we have

-3y+y=-2

step 2 combine like terms

-3y+y=-2y

now we have -2y=-2

step 3 divide each side by -2

-2/-2=1

so we can conclude that y=1

Answer:

12,228 ounces

Step-by-step explanation:

There are 128 ounces in a gallon. So multiply 128 ounces by the number of gallons.

128 x 96 = 12,228

96 bottles of perfume will fill 12 gallons.

Given that a perfume manufacturer puts 16 fluid ounces in each bottle.

We need to find how many gallons will fill 96 bottles,

To find the total number of gallons required to fill 96 bottles, we need to calculate the total volume in fluid ounces and then convert it to gallons.

Given that each bottle contains 16 fluid ounces, the total volume in fluid ounces for 96 bottles can be calculated as:

Total fluid ounces = 16 fluid ounces/bottle x 96 bottles

Total fluid ounces = 1,536 fluid ounces

To convert the total volume from fluid ounces to gallons, we use the conversion factor:

1 gallon = 128 fluid ounces

Therefore, the total volume in gallons is:

Total gallons = Total fluid ounces / 128 fluid ounces/gallon

Total gallons = 1,536 fluid ounces / 128 fluid ounces/gallon

Total gallons = 12 gallons

So, 96 bottles will fill 12 gallons.

Answer:

Must understand distance and slope formula first:

slope y_2-y_1/x_2-x_1

distance d=√((x_2-x_1)²+(y_2-y_1)²)

(Just search up the formulas if this isn't clear)

Step-by-step explanation:

For #13 take two points and put them in the distance formula remember (#,#) the first # is 'x' the second # is the 'y' in a point.

then you could simply type all that in a calculator and a single number should pop up indicating one of the lines (doesn't matter the #) then do the same for the second points (cuz you used two already you have two left) If the number is same as the first two points it's a pallelagram. (I tested it out got 7.07...)

For the slope you're doing something similar to the distance formula, you're filling out two sets of points into the slope formula if they come out the same # it's parallel.

The equation that will represent the number of grams present after n hours is [tex]A(n) = 150(0.85)^n[/tex]

3.035 grams will be left one day from now.

Step-by-step explanation:

Exponential equation for the amount of a substance:

The exponential equation for the amount of a substance is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time period.

A radioactive isotope is decaying at a rate of 15% every hour.

This means that [tex]r = 0.15[/tex]

Currently there are 150 grams of the substance.

This means that [tex]A(0) = 150[/tex]

Write an equation that will represent the number of grams present after n hours.

[tex]A(n) = A(0)(1-r)^n[/tex]

[tex]A(n) = 150(1-0.15)^n[/tex]

[tex]A(n) = 150(0.85)^n[/tex]

How much will be left one day from now?

One day is 24 hours, so this is A(24).

[tex]A(24) = 150(0.85)^{24} = 3.035[/tex]

3.035 grams will be left one day from now.

Answer:

Step-by-step explanation:

The sum of the measures of the exterior angles of a convex polygon is always 360°. If each is 60°, there are 360°/60° = 6 of them.

There are 6 sides.

The adjacent interior angle is the supplement of the exterior angle, so is ...

  180° -60° = 120°.

Each interior angle measures 120°.
