Answer:
46 of the total vehicles are minivans
Step-by-step explanation:
Let the number of minivans be x
and the number of other types of vehicles be y
From the question,
Carla noticed that for every 2 minivans, there were 5 other types of vehicles.
This means the ratio of minivans to other types of vehicles is 2:5.
Therefore,
x:y = 2:5
We can then write that
x/y = 2/5
∴ 5x = 2y ...... (1)
Also from the question,
There are 161 total vehicles in the parking lot
That is
x + y = 161 ...... (2)
From equation (2), we can write that
y = 161 - x
Put this into equation (1)
5x = 2y
Then
5x = 2(161-x)
5x = 322 -2x
5x+2x = 322
7x = 322
x = 322/7
x = 46
Since x represent the number of minivans
Hence, 46 of the total vehicles are minivans.
Some one please help and find the domain and range. If your not sure about your answer don’t give the answer unless your 100% sure.
Answer:
Domain x=1 and range is 0≤f(x)≤3
Step-by-step explanation:
Domain corresponds to the value of x and range corresponds to the value of y
Here we see the graph exists at x=1 so the domain is x=1 or simply 1 and the range is a range of values from 0 to 3 so we write it in the way
0≤f(x)≤3

1. Tara already knew 4 appetizer recipes before starting culinary school, and she will learn 3 new appetizer recipes during each week of school. Write an equation that shows the relationship between the number of weeks and the number of appetizer recipes.
(a) Define your variables.
(b) Write a linear equation that can be used to determine the number of appetizer recipes she will learn during school
(c) Solve your linear equation to determine the number of recipes that Tara will know after 18 weeks in school
(d) Explain your answer to Part 1c.
Answer:
See below.
Step-by-step explanation:
(a)
Let w = number of weeks since she started culinary school.
Let r = number of recipes she knows at the end of week w.
(b)
Each week she learns 3 new recipes. In w weeks she learns 3w new recipes.
She already knew 4 recipes before starting school.
The equation is:
r = 3w + 4
(c)
After 18 weeks of school, w = 18.
r = 3w + 4
r = 3(18) + 4
r = 54 + 4
r = 58
(d)
After 18 weeks of school, she will know 58 recipes.
She knew 4 recipes before starting school. in 18 weeks of school she learned 18 * 3 = 54 recipes. Altogether, after 18 weeks of school, she knows 58 recipes.

Luigi and Mario are growing plants for a science fair. Luigi's plant grew 11 inches in five days. Mario measured his at one foot three inches in one week. Which student has the fastest growing plants? Show work to justify your answer.
Answer:
Luigi has the fastest growing plant
Step-by-step explanation:
Luigi and Mario are growing plants for a science fair.
Mario measured his at one foot three inches in one week.
1 foot = 12 inches
Hence, the height of Mario's plant in one week
= 12 inches + 3 inches = 15 inches
Luigi's plant grew 11 inches in five days.
7 days = 1 week
5 days = 11 Inches
7 days = x
5x = 7 × 11
x = 77/5
x = 15.4 inches
Which student has the fastest growing plants?
Luigi has the fastest growing plants

Which multiplication expression is equal to 5/6 divided 1/2 ?
A: 6/5 times 1/2
B: 5/6 times 1/2
C: 6/5 times 2/1
D: 5/6 times 2/1
Answer:
D
Step-by-step explanation:
Another way to divide fractions is to multiply by the reciprocal, which is basically the fraction with the denominator put on top and the numerator put on the bottom.
The reciprocal of 1/2 is 2/1, so the correct answer choice is D
Hope this helps! Good luck :)
The multiplication expression that is equal to 5/6 ÷ 1/2 is 5/6 times 2/1, which simplifies to 5/3.
Thus, option (D) is correct.
Given: 5/6 ÷ 1/2
To find the reciprocal of 1/2, invert the fraction, which means switching the numerator and denominator:
Reciprocal of 1/2 = 2/1
Now, multiply the first fraction (5/6) by the reciprocal (2/1):
= (5/6) × (2/1)
Multiplying the numerators and denominators:
= (5 × 2) / (6 × 1)
= 10/6
To simplify the fraction, divide the numerator and denominator by their greatest common divisor (GCD):
GCD(10, 6) = 2
= (10/2) / (6/2)
= 5/3
Therefore, the equivalent multiplication expression is5/6 times 2/1.

What is the slope of a line perpendicular to the line y=8x+1
The slope of a line perpendicular to the line y=8x+1 is -1/8.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The product of slopes of line are m₁m₂=-1
The equation of line is y=8x+1
m₁=8
We need to find m₂

The area of a rectangular wall of a barn is 12 square feet. Its length is 14 feet longer than the width. Find the length and width of the wall of the barn.
Answer:
w = 0.81 ft
l = 14.81 ft
Step-by-step explanation:
The equation of the area of a rectangle is given by:
[tex]A_{r}=l*w[/tex]
But we know that l=14+w and [tex]A_{r}=12 ft^{2}[/tex]
So we will have:
[tex]12=(14+w)*w=14w+w^{2}[/tex]
[tex]w^{2}+14w-12=0[/tex]
Solving this quadratic equation we have:
w = 0.81 ft
We just take the positive solution
So, the length will be l = 14 + 0.81 = 14.81 ft

The greatest ocean depth of -35,836 feet (35,836 feet below sea level). An unmanned research submarine dives form sea level to that depth in 17 equal steps. At what depth is the submarine located after the first step?
Answer:
2,108 feets below sea level
Step-by-step explanation:
Given that:
Greatest depth = - 35,836 feets
Unmanned submarine dives to the depth in 17 equal steps
That is ; 17 equal steps was taken to reach a depth of 35,836 feets below sea level.
Depth of submarine after first step :
Depth per step :
Total depth / number of steps
35836 / 17
=2,108 feets below sea level.
Hence, Depth of submarine after first step = 2,108 feets below sea level.
