Kalvin sells bottles of water at baseball games. He pays $0.75 per bottle and $3.78 for the ice to keep the water cold. Let b represent the
number of bottles of water he buys and C represent his total cost.
Which equation shows the relationship between his total cost and the number of bottles?
O A. C = b +0.75
O B. C = b +3.78
OC. C = 0.75 +3.78
OD. C = 3.78b+0.75
Answers
Multiply the cost per bottle by the number of bottles and add that to the cost of ice.
Answer : C = 0.75b + 3.78
Answer:
C = 0.75b + 3.78
Use the equation to answer the questions. Round both answers to nearest whole number. Y=51.75−1.25X If Y equals 4, what is X?
Answers
Answer:
38.2, or 38 1/2
Step-by-step explanation:
Steps for Solving Linear Equation:
4=51.75−1.25x
Swap sides so that all variable terms are on the left hand side.
51.75−1.25x=4
Subtract 51.75 from both sides.
−1.25x=4−51.75
Subtract 51.75 from 4 to get −47.75.
−1.25x=−47.75
Divide both sides by −1.25.
x=−1.25−47.75
Expand −1.25−47.75≈38.2 by multiplying both numerator and the denominator by 100.
x=−125−4775
Reduce the fraction −125−4775≈38.2 to lowest terms by extracting and canceling out −25.

Find the center of this circle by completing the square. x^2+y^2-6x+8y+10=0
Show work
Answers
Answer:
Center: (3, - 4)
Step-by-step explanation:
We can start to solve this problem by converting this equation into standard form. In other words, by completing the square --- (1)
Subtract " 10 " from either side of the equation x² + y² - 6x + 8y + 10 = 0
x² + y² - 6x + 8y = - 10
Step 1: Complete the square for the expression " x² - 6x "
Using the quadratic equation ax² + bx + c we know that a = 1, b = - 6, c = 0. Assume that d = b / 2a. We have...
d = - 6 / 2(1) = - 6 / 2 = - 3
Now let's assume that e = c - (b²) / 4a...
e = 0 - (-6)² / 4(1) = 0 - 36 / 4 = 0 - 9 = 9 (Substitute values d and e)
(x - 3)² - 9
Step 2: Respectively we can complete the square for the remaining expression " y² + 8y "
Here a = 1, b = 8, c = 0
d = 8 / 2(1) = 8 / 2 = 4
e = 0 - (8)² / 4(1) = 0 - 64 / 4 = 0 - 16 = - 16 (Substitute values)
(y + 4)² - 16
This leaves us with the expression " (x - 3)² - 9 + (y + 4)² - 16 = - 10. " If we simplify this a bit further it leaves us with the following circle equation. Using this we can identify the center of the circle as well --- (2)
[tex]\mathrm{Standard}\:\mathrm{Circle}\:\mathrm{Equation} : (x - 3)^2 + (y +4)^2 = 15,\\\mathrm{General}\:\mathrm{Form} : (x - h)^2 + (y +k)^2 = r^2,\\\mathrm{Properties} : \mathrm{Center} = (3, - 4), \mathrm{Radius} = \sqrt{15}[/tex]
As you can see our center here is (3, - 4)
Solve the following System of Three Equations: x−3y+z=−15
2x+y−z=−2
x+y+2z=1
Answers
Answer:
x = -3 , y = 4 , z = 0
Step-by-step explanation:
Solve the following system:
{x - 3 y + z = -15
2 x + y - z = -2
x + y + 2 z = 1
Hint: | Choose an equation and a variable to solve for.
In the first equation, look to solve for z:
{x - 3 y + z = -15
2 x + y - z = -2
x + y + 2 z = 1
Hint: | Solve for z.
Subtract x - 3 y from both sides:
{z = 3 y + (-x - 15)
2 x + y - z = -2
x + y + 2 z = 1
Hint: | Perform a substitution.
Substitute z = -15 - x + 3 y into the second and third equations:
{z = -15 - x + 3 y
15 + 3 x - 2 y = -2
x + y + 2 (-15 - x + 3 y) = 1
Hint: | Expand the left hand side of the equation x + y + 2 (-15 - x + 3 y) = 1.
x + y + 2 (-15 - x + 3 y) = x + y + (-30 - 2 x + 6 y) = -30 - x + 7 y:
{z = -15 - x + 3 y
15 + 3 x - 2 y = -2
-30 - x + 7 y = 1
Hint: | Choose an equation and a variable to solve for.
In the second equation, look to solve for x:
{z = -15 - x + 3 y
15 + 3 x - 2 y = -2
-30 - x + 7 y = 1
Hint: | Isolate terms with x to the left hand side.
Subtract 15 - 2 y from both sides:
{z = -15 - x + 3 y
3 x = 2 y - 17
-30 - x + 7 y = 1
Hint: | Solve for x.
Divide both sides by 3:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
-30 - x + 7 y = 1
Hint: | Perform a substitution.
Substitute x = (2 y)/3 - 17/3 into the third equation:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
(19 y)/3 - 73/3 = 1
Hint: | Choose an equation and a variable to solve for.
In the third equation, look to solve for y:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
(19 y)/3 - 73/3 = 1
Hint: | Isolate terms with y to the left hand side.
Add 73/3 to both sides:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
(19 y)/3 = 76/3
Hint: | Solve for y.
Multiply both sides by 3/19:
{z = -15 - x + 3 y
x = (2 y)/3 - 17/3
y = 4
Hint: | Perform a back substitution.
Substitute y = 4 into the first and second equations:
{z = -x - 3
x = -3
y = 4
Hint: | Perform a back substitution.
Substitute x = -3 into the first equation:
{z = 0
x = -3
y = 4
Hint: | Sort results.
Collect results in alphabetical order:
Answer: {x = -3 , y = 4 , z = 0

What is a magic square?A magic square is a square grid of numbers, typically integers, where the numbers in each row, column, and diagonal add up to the same constant value.
Here,
To create a magic square using the numbers 6, 8, 10, 13, 15, 17, 20, 22, and 24, we can follow these steps,
Start by placing the number 15 in the center square of the grid.
Place the number 6 in one corner of the grid. We'll choose the top left corner for this example.
Place the number 24 in the opposite corner. We'll choose the bottom right corner for this example.
Place the remaining numbers in the empty squares of the grid, following these rules:
a. If a square is already occupied, move to the next square in the same direction.
b. If you reach the edge of the grid, wrap around to the other side.
c. If you reach a square that is diagonally adjacent to a previously filled square, move to the next empty square in a clockwise direction.
Using these rules, we can fill in the rest of the grid as follows:
| 6 | 8 | 10 |
| 13 | 15 | 17 |
| 20 | 22 | 24 |

Answers
Answer:
Larger angle= 153°
Smaller angle= 27°
Step-by-step explanation:
Supplementary angles are two angles that add up to 180°
Let the smaller angle= x
Let the larger angle= y
X+y= 180... equation one
Y-126= x..... equation two
(Y-126) +y = 180

2y= 306
Y= 153°
Y-126= x.

Answer:
-18
Step-by-step explanation:
We are given the expression:

A lumber company is making boards that are 2599.0 millimeters tall. If the boards are too long they must be trimmed, and if the boards are too short they cannot be used. A sample of 23 is made, and it is found that they have a mean of 2600.3 millimeters with a standard deviation of 13.0. A level of significance of 0.05 will be used to determine if the boards are either too long or too short. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the boards are either too long or too short?
Answers
Answer:
There is no sufficient evidence to support the claim that the boards are either too long or too short
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 2599.0[/tex]
The sample size is [tex]n = 23[/tex]
The sample mean is [tex]\= x = 2600.3 \ mm[/tex]
The standard deviation is [tex]\sigma = 13.0[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \mu = 2599.0[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 2599.0[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{ \= x - \mu }{ \frac{\sigma}{ \sqrt{n} } }[/tex]
=> [tex]t = \frac{ 2600.3 - 2599.0 }{ \frac{13}{ \sqrt{ 23} } }[/tex]
=> [tex]t = 0.3689[/tex]
Now from the normal distribution table the critical value of [tex]\alpha[/tex] is
[tex]Z_{\alpha } = 1.645[/tex]
Hence from the evaluated and obtained value we see that
[tex]t < Z_{\alpha }[/tex]
Hence we fail to reject the null hypothesis
Thus we can conclude that there is no sufficient evidence to support the claim that the boards are either too long or too short
