What would the slope of a line be that is perpendicular to the line 3x + 2y = 6?
And why is it right
Answers
Answer:
2/3
Step-by-step explanation:
The slope of a line that is perpendicular to another line must be the negative reciprocal of the other line. This means that the slope is flipped (3/2 would be 2/3, or 5 would be 1/5) and that the sign is also changed. If the slope of the other line is positive, then the slope of this line would be negative, and vice-versa.
First, we try to get the variable y by itself, so subtract 3x from that side of the equation and then divide everything by 2. So, it would now be y= -3/2 + 3.
Then, you find the negative reciprocal of 'm', so -3/2 would be change to 2/3

If there are a total of 180 school days, how many times will the cafeteria serve hot dogs and hamburgers together this year?
Answers
Answer:
The Answer is 12 days or times.
Step-by-step explanation:
The LCM of 6 is 3 and 2, the LCM of 4 is 2 and 1, so we multiply 3 by 2 and 4 by 2 together to get 12, which is the number of days or times.

Step-by-step explanation:
The Oates family went out to
dinner. The price of the meal was
$33.95. They left a 15% tip.
What was the total cost?
Answers
Answer:
$39.04
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the amount of tip that was left, then add the value to the cost of the meal. The amount of tip given can be found by dividing the percent value of the tip by (100) and then multiplying the result by the price of the meal.
2.Find the amount of tip
To find the amount of tip that was left, divide the percent value of the tip by (100). This technique converts the percent into a decimal. After doing so, multiply the result by the cost of the meal.
Tip as a percent: 15%
Tip as a decimal: 0.15
Amount of tip left:
33.95 * 0.15 = 5.0925
Round the result
~5.09
3.Find the total bill
Disincluding the tax, one now has to add the tip to the cost of the meal to find the total amount paid.
(tip) + (price)
= (5.09) + (33.95)
= (39.04)
A monthly salary is $1622.31. It is given an increase of 3.8%. After the first increase, it receives a second increase of 6.2%. What is the new monthly salary after both increases? Round your answer to two decimal places. Do not put the $ sign in your answer or any units. Only put the number value for your answer.
Answers
Answer:
the new monthly salary after both increase is 1,788.37
Step-by-step explanation:
The monthly salary is 1,622.31
There is an increase of 3.8%
So, the salary after first increase is
= 1,622.31 × (1 + 3.8%)
= 1,683.96
Now there is a second increase of 6.2%, so the salary after second increase is
= 1,683.96 × (1 + 6.2%)
= 1,788.37
Hence, the new monthly salary after both increase is 1,788.37

Peter is 8 years younger than Jonne. In 5 years time, Jonne will be twice as old as Peter. How old is Peter now?
Answers
Answer:
Age of Peter = 3 year
Step-by-step explanation:
Given:
Peter is 8 years younger than Jonne
Assume;
Age of Jonne = a
So,
Age of Peter = a - 8
After 5 years,
2[a - 8 + 5] = a + 5
2a - 6 = a + 5
a = 11
Age of Jonne = 11
Age of Peter = 11 - 8
Age of Peter = 3 year

The equation is ;
4x - y = 13
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from what we are given, let us write the second equation in the general form
x + 4y = 10
4y = -x + 20
y = -1/4x + 20/4
y = -1/4x + 5
mathematically, when two lines are perpendicular, the product of their slope is -1
So for the second line with slope m2
m2 * -1/4 = -1
m2 = 4
So, using the general form, we have the equation as;
y = 4x + b
To get the value of b, we substitute the coordinates of the given point (3,-1)
-1 = 4(3) + b
-1 = 12 + b
b = -1-12
b = -13
So the equation is;
y = 4x - 13 which can be rewritten as;
4x-y = 13
A person invested $7,400 in an account growing at a rate allowing the money to
double every 6 years. How much money would be in the account after 4 years, to the

Answers
Using an exponential function, it is found that $11,747 will be in the account after 4 years.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem, considering the initial investment of $7,400, and the fact that it doubles every 6 years, the equation is given by:
[tex]A(t) = 7400(2)^{\frac{t}{6}}[/tex]
Hence the amount in 4 years is given by:
[tex]A(4) = 7400(2)^{\frac{4}{6}} = 11747[/tex]

Adrian and Violetta gat a soccer ball. The soccer ball is size 4.They want it to be size 5.They know the diameter is 9 inches. Find the volume of the soccer ball.
Answers
Answer:
382 inches
Step-by-step explanation:
Given that :
The size of the soccer ball that Adrian and Violetta got is = 4
The diameter of the soccer ball is = 9 inches
Therefore, the radius of the soccer ball is, r = [tex]$\frac{9}{2}$[/tex] inches
So the volume of the soccer ball is :
[tex]V = \frac{4}{3} \pi r^3[/tex]
[tex]V = \frac{4}{3} \times \frac{22}{7} \times \left(\frac{9}{2}\right)^3[/tex]
[tex]V = \frac{4}{3} \times \frac{22}{7} \times \frac{9}{2} \times \frac{9}{2} \times \frac{9}{2}[/tex]
V ≈ 382 inches
Sam rented a truck for one day. There was a base fee of $14.95, and there was an additional charge of 97 cents for each mile driven. Sam had to pay $265.21 when he returned the truck. For how many miles did he drive the truck?
Answers
Answer:
258 miles
Step-by-step explanation:
y = # miles truck driven
m = each mile driven
y = 14.95 + 0.97m
265.21 = 14.95 + 0.97m
250.26 = 0.97m
m = 258

The goal of the students in the club was to raise $500. They sold 43 flowerpots. By what amount did the students exceed their goal of raising $500?
Answers
Answer:
Exceeded by 145 dollars.
Step-by-step explanation:
First you multiply 15 by 43 because each pot costs 15 dollars and they sold 45.
Then you get the answer of 645 and the goal was 500 so that means you need to subtract to see how much they exceeded by.
Subtract 500 from 645 and you get the answer of 145.
So they exceeded 145 dollars.

Mia found the volume of a rectangular prism to be 840 mm3. As she was telling her father about it. she remembered that the base had a length of 10 mm and a width of 12 mm, but she could not remember the height maybe there is a way you can find it by going backwards . her father suggested. Can you help Mia find the height of her prism. Explain your solution.
Answers
Answer:
H = 7mm
Step-by-step explanation:
Height of Prism
So to calculate the height, multiply L · H · W. But since there is no height we will multiply what is given and then divide the volume by the product. For this case, the volume of the prism is 840 and its length is 10 and its width is 12. Multiply 10 and 12 then dividing 840 by 120. The height of the prism is 7.
Solve
Volume if the rectangular prism is given by the formula
V = L · H · W
Length, Height, Width of the prism
L = 10mm H = 12mm Volume = 840mm³
10 · 12 · h = 840
∴ 840 ÷ 120 = 7
H = 7mm
