The next model sports car will cost 5.2% more than the current model. The current model costs $55,000. How much will the price increase in dollars? What will be the price of the next model?
Answer: The price increase = $2,860.
The price of the next model will be $57,860.
Step-by-step explanation:
Given: The next model sports car will cost 5.2% more than the current model.
Current model costs $55,000.
Price increase = 5.2% of (Cost of current model)
= (0.052) x ($55000)
= $ 2860
So, the price increase = $2860.
Price of the next model = Cost of current model + price increase
= $(55000+2860)
= $ 57,860
Hence, the price of the next model will be $57,860.

Aminer started at 8 feet above sea level
and then traveled 23 feet straight down
into a mine shaft. What was the miner's
elevation after traveling down the mine
shaft?
Answer:
-15 ft or 15 ft below sea level
Step-by-step explanation:
He started at +8 ft.
Then he went 23 ft down, that is -23 ft.
8 ft + (-23 ft) = 8 ft - 23 ft = -15 ft
Answer: -15 ft
Describe the steps needed to solve 8x-12y=-3 for y.
Answer:
y = (2 x)/3 + 1/4
Step-by-step explanation:
Solve for y:
8 x - 12 y = -3
Subtract 8 x from both sides:
-12 y = -8 x - 3
Divide both sides by -12:
Answer: y = (2 x)/3 + 1/4
Below the two way table is given for a class of students if a student is selected at random find the probability the student is male round to the nearest whole percent
Answer:
47%
Step-by-step explanation:
Total number of males=14
Total number of females =16
Total number of students =16+14
=30
Probability of a selecting a male student
[tex] = \frac{number \: of \: male \: students}{total \: number \: of \: students} \\ = \frac{14}{30} \\ \frac{7}{15} \\ to \: the \: nearest \: whole \: percent \\ = \frac{7}{15} \times 100 \\ = 46.66 [/tex]

Monica needs to gain 10 pounds in order to be able to donate blood. She gained 5/6 pound the first week, 3/4 pound each of the next two weeks, 3/4 pound the fourth week, and lost 3/8 pound the fifth week. How many more pounds does she still have to gain?
Answer: [tex]7\dfrac{7}{24}\text{ pounds}[/tex]
Step-by-step explanation:
Given, Monica gained weight in first week = [tex]\dfrac{5}{6}[/tex] pounds
She gained weight in second week = [tex]\dfrac34[/tex] pounds
She gained weight in third week = [tex]\dfrac34[/tex] pounds
She gained weight in fourth week = [tex]\dfrac34[/tex] pounds
She lost weight in fifth week = [tex]\dfrac38[/tex] pounds
Now, net weight she gained= [tex]\dfrac{5}{6}+\dfrac34+\dfrac34+\dfrac34-\dfrac{3}{8}[/tex]
[tex]=\dfrac{20+18+18+18-9}{24}\\\\=\dfrac{65}{24}\\\\=2\dfrac{17}{65}\text{ pounds}[/tex]
She need to gain [tex]10-\dfrac{65}{24}=\dfrac{240-65}{24}=7\dfrac{7}{24}\text{ pounds}[/tex]
Hence, she still have to gain [tex]7\dfrac{7}{24}\text{ pounds}[/tex]more.

What is the equation for the line through P that is parallel to L and perpendicular to L. P(0,0), L:y=-x+2
Answer:
A. The equation of the line parallel to line L is y = – x
B. The equation of the line perpendicular to line L is y = x
Step-by-step explanation:
We'll begin by calculating the slope of line L.
This can be obtained as follow:
y = –x + 2
Comparing the above equation with:
y = mx + c
We can see that the slope (m) = –1.
Therefore, the slope of line L is –1
A. Determination of the equation of the line parallel to line L. This is illustrated below:
When two lines are parallel, their slope (m) is equal i.e
m1 = m2
m1 = – 1
– 1 = m2
This means that the slope of the line parallel to line L is –1
Now we shall determine the equation of the line parallel to line L as follow:
Coordinate = (0, 0)
x1 coordinate = 0
y1 coordinate = 0
Slope (m) = –1
y – y1 = m(x – x1)
y – 0 = –1 (x – 0)
y = – x
Therefore, the equation of the line parallel to line L is y = – x
B. Determination of the equation of the line perpendicular to line L. This is illustrated below:
When two lines are perpendicular, the product of their slope (m) is –1 i.e
m1 • m2 = – 1
but m1 = –1
–1 x m2 = – 1
Divide both side by – 1
m2 = –1/–1
m2 = 1
Now, we shall determine the equation of the line perpendicular to line L as follow:
Coordinate = (0, 0)
x1 coordinate = 0
y1 coordinate = 0
Slope (m) = 1
y – y1 = m(x – x1)
y – 0 = 1 (x – 0)
y = x
Therefore, the equation of the line perpendicular to line L is y = x

Chicken eggs can be categorized as large if they weigh at least 2 ounces. Clare weighs 48 large eggs and finds that they have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces. Interpret 0.08 ounces in this situation.
Answer:
0.08 ounces is interpreted as the Mean Absolute Deviation and this means that
the various weights of each of the 48 eggs deviates from the mean of the egg (2.1 ounces)by 0.08 ounces.
Step-by-step explanation:
Mean Absolute Deviation of a data set is defined as the distance or the deviation between a given data set and the calculated mean.
Mean Absolute Deviation tells us about how much a data set varies from it's mean.
From the above question, we are told that after weighing 48 eggs we have a mean of 2.1 ounces and mean deviation of 0.08 ounces
Therefore this means that the various weights of each of the 48 eggs deviates from the mean of the egg (2.1 ounces)by 0.08 ounces

Is the point (2,4) a solution of the equation y= 17x- 12?
Answer: Hi!
So, to find the answer to this question, we would substitute the variables in the equation with the x, y coordinated of the solution.
x = 2 and 4 = y
Our equation now looks like this:
4 = 17(2) - 12
4 = 34 - 12
4 = 22
This is not a true statement! Therefore, the point (2,4) cannot be a solution for this equation.

A ball is thrown vertically upward. After t seconds, its height h, in feet, is given by the function LaTeX: h\left(t\right)=-16t^2+64th ( t ) = − 16 t 2 + 64 t. How many seconds will it take the ball to reach its maximum height?
Answer:
The time it will take for the ball to reach maximum height of 64 feet is 2 seconds
Step-by-step explanation:
The given equation for the height, h, in feet the ball reaches is given by the function;
h(t) = -16·t² + 64·t
To reach maximum height, [tex]h_{max}[/tex], we have;
At [tex]h_{max}[/tex], we have;
[tex]\dfrac{\mathrm{d} h}{\mathrm{d} t} = 0[/tex]
[tex]\dfrac{\mathrm{d} \left (-16\cdot t^{2} + 64\cdot t \right )}{\mathrm{d} t} = 0[/tex]
Which gives;
64 -32·t = 0
64 = 32·t
t = 64/32 = 2 seconds
Therefore, it will take 2 seconds for the ball to reach maximum height
The maximum height reached is given as follows;
h(2) = -16×2² + 64×2 = 64 feet
The time it will take for the ball to reach maximum height of 64 feet is 2 seconds.
What are the solutions of |3x + 2| > 9?
Absolute value means the distance the number zero.
(3x+2) is (3x+2) from 0.
So right now, 3x+2>9, you have to get rid of the 2 on the left side (because you don't want the variable and the constant on the same side) .
Subtract 2 from the left side and 2 from the right.
Now it is 3x > 9-2
9-2=7
3x > 7

A bike wheel. The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What is the weight of each tire in pounds? There are 453.592 grams in one pound. Round answers to 2 decimal places. 800 grams = pounds 700 grams = pounds
Answer:
a. 800 grams = 1.76 pounds
b. 700 grams = 1.54 pounds
Step-by-step explanation:
Here is a weight conversion problem.
In this question, we shall be making conversions from grams to pounds.
Kindly note that 453.592 grams = 1 pound as stated in the question
a. 800 grams
Kindly recall;
453.592 grams = 1 pound
800 grams = x pound
Thus;
453.592 * x = 800 * 1
x = 800/453.592
x = 1.764 pounds which is 1.76 pounds to 2 decimal places
b. 700 grams
1 pound = 453.592 grams
y pound = 700 grams
y * 453.592 = 700 * 1
y = 700/453.592
y = 1.543 pounds which is 1.54 to 2 decimal places
Answer:
1.76

6n+5n simplify expressions
Answer:
The answer is 11n.
Step-by-step explanation:
This is because 6n and 5n have the common term of n and you can add them up as if it were just 6 + 5.
6n + 5n = 11n
Answer:
11n
Step-by-step explanation:
We are given the expression:
6n+5n
and asked to simplify.
To simplify, we must combine like terms. Let's analyze the terms.
6n ⇒ has a variable "n"
5n ⇒ also has a variable "n"
The like terms in this expression are the terms with a variable, n.
To combine like terms, add the coefficients and leave an n on the end.
(6+5)n
11n
The expression 6n+5n simplified is 11n.

12. Mr. Gooding works at the local appliance store. His base salary is $360a week plus an
1/6
additional of his sales. If his total salary for the week is $570, what were his total sales for that
week?
Answer: total sales $1260
Step-by-step explanation:
GIVEN
Base salary: $360
Additional salary: 1/6 of total sale
Total salary: $570
-------------------------------------------------------
Let x= the total sales
360+(1/6)x=570
Subtract 360 on both sides
(1/6)x=210
Divide 1/6 on both sides
x=210 ÷ (1/6)
Turn division of fraction into multiplying its reciprocal
x=210 × 6
Simplify
x=1260
