Harper knows he is 50 yards from school. The map on his phone shows that the school is 34 inch from his current location.
How far is Harper from home, if the map shows the distance as 3 inches?
Answers
Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. We know that 1 yard is 36 inches, therefore, 50 yards expressed in inches is:
(50)(36)=1800in
2. If he is 50 yards from school and the map shows that the school is 34 inches from his current location, when it shows 3 inches the real distance is:
(1800)(3in)/24in=158.82
3. If you can to express it in yards:
158.82/36=4.41yd
Therefore, the answer is: 158.82 inches or 4.41 yards.

What is the slope of a line that is perpendicular to the line y = -1/2x + 5
Answers
To find the slope of a line perpendicular to another line, we simply need to find the inverse negative of the slope of the first one. This makes sense if you visualize it on a graph or in your head.
The slope of the line given is -1/2.
To find the inverse negative we first inverse the number, then take then negatuve of that (or opposite order).
The inverse of -1/2 is, -2 (switch the numerator and denominator or do to the power of -1, ^-1).
The negative of -2 is, 2.
Therefore the slope of the line perpendicular to y = -1/2x + 5 is 2.

Which is the equation of the function?
Answers
Step-by-step explanation:
A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

a square has a perimeter of 72 units. if its length measures 3y and its width measures 2x, what is the area of the square
Answers
Answer:
324
Step-by-step explanation:
square has 4 sides.
perimeter adds all sides to make 72
72/4=18 units each side
length * width =area of square
square has all sides equal, so 3y and 2x are tricks to confuse. All sides are 18.
18*18= 324

A particular plant root grows 2.5 inches per month. How many centimeters is the plant root growing per month? (1 inch = 2.54 centimeters).
Answers
Answer:
The plant root is growing 6.35 cm per month.
Step-by-step explanation:
This is a conversion problem. You are converting 2.5 inches to centimeters.
2. 5 inches * 2.54 cm/1 inch
inches cancels out and now you are left with multiplying 2.5 and 2.54.
2.5 * 2.54 cm = 6.35 cm

Answer:
yesnoyesnoyesStep-by-step explanation:
The function is quadratic if the highest degree of any term is 2. Equations 2 and 4 have degree 1, so are linear (not quadratic) functions. Equations 1, 3, and 5 have terms of degree 2 (at most), so are quadratic functions.
_____
We assume that two terms of degree 2 in equation 5 is intentional. If one of those is supposed to be of degree 3 (or more), then that function is not quadratic.

What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) tru
Answers
Answer: 1/10 or 0.1
Step-by-step explanation:
-(-7 - 4x) = -2(3x - 4)
7 + 4x = -6x + 8
* subtract 7 from both sides
4x = -6x + 1
* Add 6x to both sides
10 x = 1
* Divide both sides by 10
x = 1/10 or 0.10
This step makes sure that you know to distribute the negative.
-5x + [-(-7-4x)] = -2(3x-4)
Continue to simplify. Start by distributing across the parentheses.
-5x+(7+4x)= -6x+8
-5x+4x+7= -6x+8
-x+7=-6x+8
Once you can’t simplify either side any more, you try and isolate the variable onto one side.
-x+7=-6x+8

________
7=-5x+8
Then isolate the constants into one side.

Step-by-step explanation:
y and 67 are vertically opposite angles.
Vertically opposite angles are equal.

x and 67 are linear pair angles.
Sum of linear pair angles is 180,
x + 67 = 180
x = 180 - 67
x = 113

Answer:
Exact area = 1800 - 450pi square cm
Approximate area = 387 square cm
I used 3.14 for pi to get the approximate value.
============================================================
Explanation:
Check out the diagram below.
As the diagram shows, the largest radius possible is half of the shortest dimension of this rectangle. So the radius of each identical circle is 30/2 = 15 cm. The radius cannot exceed this value, or else the circle will spill outside the rectangle.
The area of one circle would be
A = pi*r^2
A = pi*15^2
A = pi*225
A = 225pi
Two identical circles like this combine to a total area of 2A = 2*225pi = 450pi square cm.
The area of the brown shaded region in the figure, aka the amount of cardboard leftover, is exactly 1800 - 450pi. The 1800 is from the computation of 60*30 = 1800, which is the area of the original rectangle before we made any cuts.
If we wanted to find the approximate area, then we could use pi = 3.14 to get
1800 - 450pi = 1800 - 450*3.14 = 387
The approximate area remaining is 387 square cm. This value is approximate because pi = 3.14 is approximate. If you were to use more decimal digits of pi, then you'd get some other approximate area.
