Q1: The temperature outside dropped 13°F in 7 hours.
The final temperature was -2°F. What was the starting temperature?
Answer:
11
Step-by-step explanation:
To get the answer, we need to add 13 to -2.
First, we need to add 2 to -2 to get it to 0.
Now we add 11 to zero to get 11.

Answer:
6x+2y=8
Step-by-step explanation:
We can multiply both sides of the equation by 3 to get 6x+2y=8.
(Note there is more than one possible answer, you could've multiplied both sides by any number.)
If f(x) = 3(x+5) +-, what is f(a+2)?
xx, (a?
X
Given a defined function
f(x), we can evaluate the function at any constant by replacing every x
with that constant.So if f(x)=3x+5x, then f(a+2)=3(a+2)\+5a+2

Answer:
If you were to make these two equations in slope intercept form, here's what it would be like;
First the formula for slope intercept form is, y = mx + b
where m represents the slope and b is the y intercept(where the line meets the y axis)
First equation;
x + y = 3
we need to isolate y so we subtract x from both sides
-x -x
y = -x + 3 (we put the -x before the 3 because that's how the formula is formatted)
Second equation;
2x + 3y = 7
Isolate y by subtracting 2x away from both sides
-2x -2x
3y = -2x + 7, y is not fully isolated because it has a coefficient and it's supposed to be just y, so we divide both sides by 3:
/3 /3
y = -2/3x + 2 1/3

Population (thousands) Land Area (square miles) Total Income (billions of dollars)
159.2 1,536.7 4.8
Determine the per capita income for this county. Round to the nearest cent.
The per capita income is the ratio of the total income to the population
The per capita income of the county is $30150.75
How to determine the per capita incomeThe given parameters are:
Population = 159.2 thousand
Land area = 1,536.7 square miles
Total income = $4.8 billion
The per capita income is then calculated as:
Per capita income (p) = total income /population
So, we have:
[tex]p = \frac{\$4.8\ billion}{159.2\ thousand}[/tex]
Evaluate the quotient
[tex]p = \$30150.75[/tex]
Hence, the per capita income of the county is $30150.75

Graph circles A and B in the coordinate plane. circle A with center at (0,0) and radius of 6,circle B with center at (-4,-2) and radius of 4.
A circle can be represented as an equation or on a graph
The equations of the circles are [tex]x^2 + y^2 = 36[/tex] and [tex](x + 4)^2 + (y + 2)^2 = 16[/tex]
How to graph the circlesThe equation of a circle is represented as:
[tex](x - a)^2 + (y - b)^2 =r^2[/tex]
Where:
Center = (a,b)
Radius = r
For circle A, we have the equation to be:

[tex]x^2 + y^2 = 36[/tex]
For circle B, we have the equation to be:
[tex](x + 4)^2 + (y + 2)^2 =4^2[/tex]
[tex](x + 4)^2 + (y + 2)^2 = 16[/tex]
Hence, the equations of the circles are [tex]x^2 + y^2 = 36[/tex] and [tex](x + 4)^2 + (y + 2)^2 = 16[/tex]

The volume of this right prism is 240.5 ft³. What is the height, x, of the prism? Enter your answer as a decimal in the box.
Answer:
7.4 is the correct answer
Step-by-step explanation:
Height 'x' of the given right prism is 7.4 feet.
Volume of right prism:What information do we have?
Height of base = 5 ft
Length of first parallel line = 5 ft
Length of Second parallel line = 8 ft
Volume of prism = 240.5 ft³
Volume of prism = Area of base × height
Volume of prism = (1/2)(sum of parallel line)(Height) × height
240.5 = (1/2)(5+8)(5) × height
240.5 = (1/2)(13)(5) × height
240.5 = 32.5 × height
Height of prism = 7.4 feet

A farmer sells 8.9 kilograms of pears and apples at the farmer's market.
3
4
of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Answer:
2.225 kg
Step-by-step explanation:
We know that the total weight the farmer sold was 8.9 kilograms.
- 3/4 of this weight is apples, and the rest is pears.
Therefore, to calculate the amount of kilograms of pears she sold at the farmer's market (which you can call x), you need to apply the following procedure.
The kinetic energy of an object is given by:
Kinetic energy = 1/2 * mass * velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0. All of the kinetic energy is converted to potential energy, and the pendulum starts moving in the opposite direction after this point in time.
Answer:
TYSM!! I wanted to know how to calculate the kinetic energy of an object for so long!
A pendulum at the top of its swing, when it stops moving does not have any speed and therefore it has no kinetic energy.
What is kinetic energy?Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force.
Given that, Kinetic energy = 1/2 × mass × velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0.
Here, mass m = 0, This shows that the pendulum has no mass and
velocity (v) = 0 meaning the velocity is zero, it is stopped at once.
The velocity that is moving one way or direction can be said to be in a positive direction or positive velocity.
It does slows down when it reaches the top of its swing then move again back to the opposite direction making it to move in the opposite or negative direction with negative velocity. This make a positive velocity and a negative velocity which has pass through to be zero.
Therefore, a pendulum at the top of its swing, when it stops moving does not have any speed and therefore it has no kinetic energy.
