Answer:
Answer is equation C
Step-by-step explanation:
They are converting Celsius temperature to Fahrenheit temperature.
F = 1.8C + 32
F = 1.8(0) + 32 = 32 Fahrenheit
F = 1.8(30) + 32 = 86 Fahrenheit
F = 1.8(100) + 32 = 212 Fahrenheit
Answer:
C) F = 1.8C + 32
Step-by-step explanation:
Hello! The easiest way to do this is to substitute the numbers from your table into your possible answer choices until you find numbers that make a true/correct statement.
For A:
F = 32C + 1.8 <== substitute any number for F and C from your table
32 = 32(0) + 1.8 <== multiply
32 = 0 + 1.8 <== add
32 = 1.8
This statement is false/incorrect
For B:
C = 1.8F + 32 <== substitute any number for F and C from your table
0 = 1.8(32) + 32 <== multiply
0 = 57.6 + 32
0 = 89.6
This statement is false/incorrect
For C:
F = 1.8C + 32 <== substitute any number for F and C from your table
32 = 1.8(0) + 32 <== multiply
32 = 0 + 32 <== add
32 = 32
This statement is true/correct
For D:
C = 32F + 1.8 <== substitute any number for F and C from your table
0 = 32(32) + 1.8 <== multiply
0 = 1024 + 1.8 <== add
0 = 1025.8
This statement is false/incorrect
As we can see, the only equation that makes a true statement is C.
Therefore, the correct answer is C.

Answer:
Northside
Median: 36
Range: 32
IQR: 17
Southside:
Median: 39
Range: 38
IQR: 22
Step-by-step explanation:
Northside first
Order the ages from least to greatest
24, 28, 32, 32, 32, 36, 41, 44, 49, 49, 56
Median is 36 since it's in the middle
Subtract the greatest number from the smallest number to find the range (56-24) = 32
To find the IQR you need the ages least to greatest
24, 28, 32, 32, 32, 36, 41, 44, 49, 49, 56
Find the lower quarter = 32
Find the upper quarter = 49
Subtract 49 and 32 (49-32) = 17
Southside
The Median is the line at the middle of the box, in this case its between 38 and 40 which is 39.
The range is 61 - 23 = 38 (Greatest - least)
The IQR is 52 - 30 = 22

What is the system of linear equations for the following graph? Please just list the two equations
The equation of the blue line is y = 7x - 8 and the equation of the red line is y = -2x + 2
How to write a linear equationEquations are written as a function of two or more variables with input and output.
The standard linear equation is given in the form y = mx + b
m is the slope
b is the y-intercept
For the red line, the y-intecept is 2
Using the coordinate point on the red line (0,2) and (1, 0)
Slope = -2/1
Slope = -2
Equation of the red line is y = -2x + 2
For the blue line, we will use the coordinate points (2, 6) and (1, -1)
m = -7/-1
m = 7
-1 = 7(1) + b
-1 - 7 = b
b = -8
Hence the equation of the blue line is y = 7x - 8

The volume of a sphere is 2,000π m3. What is the surface area of the sphere to the nearest square meter?
Answer:
Volume of a sphere = 4/3 πr³
4/3 * 3.14 * r³ = 4000
4.19 * r³ = 4000
r³ = 4000 / 4.19
r = ∛1058
r = 10.19
Now, surface area = 4πr² = 4 * 3.14 * (10.19)²
S.A. = 12.56 * 104
S.A. = 1307
In short, Your Answer would be Option D) 1307 m²

Suppose ABCD is a parallelogram. If AB = 9x + 2, CD = 12x - 4, BC = x + 7, determine the length of AD.
Need help asap
======================================================
Explanation:
For any parallelogram, the opposite sides are parallel and are the same length.
AB = CD
9x+2 = 12x-4
2+4 = 12x-9x
6 = 3x
x = 6/3
x = 2
Which leads to
AB = 9x+2 = 9(2)+2 = 20CD = 12x-4 = 12(2)-4 = 20BC = x+7 = 2+7 = 9Side AD is opposite BC, so AD = BC = 9

Answer:
-8, -2, 4, 10
Step-by-step explanation:
Plug the x value into the function.
2(-6)+4 = -8
and so on for all of the values in the table.
Answer:
y = 2(-6) + 4
y = -12 + 4
y = -8
y = 2(-3) + 4
y = -9 + 4
y = -5
y = 2(0) + 4
y = 0 + 4
y = 4
y = 2(3) + 4
y = 6 + 4

Pierre has more money than Alex.
If Pierre gave Alex £20, they would have the same amount.
If Alex gave Pierre £22, then Pierre would have twice as much as Alex.
How much does each one actually have?
Answer:
Pierre has £ 146 and
Alex has £ 106
Step-by-step explanation:
Let the money with Pierre be = p
Let the money with Alex = a
If Pierre gave Alex £20, they would have the same amount.
So, we should subtract £ 20 from p and add £ 20 to a
p - 20 = a + 20
p = a + 20 + 20
p = a + 40 ----------------(I)
If Alex gave Pierre £22, then Pierre would have twice as much as Alex.
p + 22 = 2*(a -22)
p + 22 = 2a - 44
p = 2a - 44 - 22
p = 2a - 66
p -2a = - 66 -----------------(II)
Substitute p = a + 40 in equation (II)
a + 40 - 2a = -66
a - 2a + 40 = -66
-a = - 66 - 40
-a = - 106
Multiply both sides by (-1)
[tex]\boxed{a = \£ \ 106}[/tex]
Substitute a = 106 in equation (I)
p = 106 + 40
[tex]\boxed{p = \£ 146}[/tex]

Answer:
[D] (-1,3)
Step-by-step explanation:
To know which ordered pair is in the solution set of -3x+4y < 20 we first need to identify the x-value in the ordered pair and plug it into the equation. When simplify, on the condition the y-value you get is identical as the y-value in the ordered pair, then that ordered pair is a solution to the equation.

x -3 -2 -1 0 1
y=?
Answer:
x | -3 -2 -1 0 1
y | 0 -3 -4 -3 0
Step-by-step explanation:
f(x) = x² + 2x - 3
x = -3 then y = (-3)² + 2(-3) - 3 = 9 - 6 - 3 = 3 - 3 = 0
x = -2 then y = (-2)² + 2(-2) - 2 = 4 - 4 - 3 = 0 - 3 = -3
x = -1 then y = (-1)² + 2(-1) - 1 = 1 - 2 - 3 = -1 - 3 = -4
x = 0 then y = (0)² + 2(0) - 3 = 0 + 0 - 3 = 0 - 3 = -3
x = 1 then y = (1)² + 2(1) - 3 = 1 + 2 - 3 = 3 - 3 = 0

The length of the extension ladder that is against the outside wall of the house is 22.58 feet.
What is the length of the ladder?When the ladder lies against a house, a right triangle is formed. The length of the ladder is the hypotenuse. The distance from the base of the ladder to the house is the base. The lenfth off the house is the length.
To find the length of the ladder, Sin would be used:
Sin = opposite / hypotenuse
Sin 77 = 22 / h
h = 22 / 0.9743 = 22.58 feet

The deck off the back of the house creates a right triangle. The side of the deck resting against the house is the hypotenuse of the triangle. You decide to put new stain on the wood. One edge of the deck measures 15 feet and the other edge of the deck measures 20 feet. Answer the follow- ing questions: 1. What is the area of the deck? 2. Each gallon of stain covers a maximum of 350 square feet. How many do you need? 3. If each gallon costs $36.98, what will the project cost you?
Approximately 2 gallons will be needed if each gallon of stain and the project will cost be $73.96 if each gallon costs $36.98
How to find the area of a triangleThe formula for calculating the area of a triangle is expressed as:
A = 0.5bh
where
base = 15feet
height = 20feet
Area of the deck = 20 * 15 * 0.5
Area of the deck is 150 square feet
Number of gallons needed = 350/150 = 2.3
Hence approximately 2 gallons will be needed if each gallon of stain covers a maximum of 350 square feet.
Cost of the two gallons = 36.98 * 2
Cost of the two gallons = $73.96
Hence the project will cost be $73.96 if each gallon costs $36.98
