Caleb’s school is five blocks due north of his home, and the library is two blocks due west of his home. If each city block is a square with sides measuring 275 feet, which of the following is the closest to the straight-line distance from Caleb’s school to the library?
Answer:
The closest straight-line distance from Caleb's school to the library is:
1480.92 feetStep-by-step explanation:
Imagine a triangle, where five blocks are a side and two blocks another side, to obtain the closest straight-line distance from Caleb's school to the library you can use the Pythagoras theorem, where the hypotenuse is the closest straight-line:
[tex]perpendicular^{2} +base^{2} =hypotenuse^{2}[/tex]Clearing the hypotenuse is:
[tex]\sqrt{perpendicular^{2}+base^{2}}= hypotenuse[/tex]Now, you only need to identify the distance in each case:
Five blocks = 275 feet * 5 = 1375 feet.
Two blocks = 275 feet * 2 = 550 feet.
At last, you must replace the distances found in the equation cleared:
[tex]\sqrt{1375 feet^{2}+550 feet^{2}}= hypotenuse[/tex]Hypotenuse or closest straight-line = 1480.92 feet.Identifying this, the closest straight-line distance from Caleb's school to the library is 1480.92 feet.

If you had a triangle with side lengths of 2, 4, and 5, and
dilated it with a scale factor of 2.5, what would be the
side lengths of the resulting image?
Answer:
5,9,12.5
Step-by-step explanation:
After dilation, the final side lengths of the triangle become -
a' = 5 units, b' = 10 units, c' = 12.5 units
What is Dilation?A dilation is an enlargement or reduction of a figure about a center of dilation by a specified scale factor [k].
Given is a triangle with side lengths of 2, 4, and 5 and is dilated with a scale factor of 2.5
We have a triangle whose side lengths are -
a = 2 units
b = 4 units
c = 5 units
Scale factor = [k] = 2.5
Now, after dilation the final side lengths will become -
a' = 2.5a = 2.5 x 2 = 5 units
b' = 2.5b = 2.5 x 4 = 10 units
c' = 2.5c = 2.5 x 5 = 12.5 units
Therefore, after dilation, the final side lengths of the triangle become -
a' = 5 units, b' = 10 units, c' = 12.5 units

Solve: 3x -6/3 = x + 3/6
Answer:
x= 1/2
Step-by-step explanation:
start by adding 6/3 to both sides. the negative 6/3 on the left side will disappear, and the right side will equal one. (6/3 + 3/6= 9/9 = 1).
Youll end up with:
3x=x+1
now, subtract x from both sides to get:
2x=1
Divide both sides by two to get
x=1/2

In the alphabet, x comes before y. Use this fact to describe a method for remembering how to write ordered pairs.
Answer:
Step-by-step explanation:
so when remembering how to write ordered pairs, think of the monkey bars. you have to get there before you can climb up, x being walking to the monkey bars and y being climbing up them. Think of the steps to get to the monkey bars compared to the fact that x is before y. getting to the monkey bars comes before climbing them, is x (run) and climbing them would be y (rise), and not the other way around because like the question said; x comes before y.
I really hope this wasn't too confusing. I'm really sorry if it was!

A veterinarian is vaccinating cattle. One bottle of vaccine is 8 ounces. How many 2 3 3 2 -ounce doses can the veterinarian get out of one bottle of vaccine? How many ounces of vaccine will be left in the bottle after she draws the maximum number of doses out?
Complete Question
A veterinarian is vaccinating cattle. One bottle of vaccine is 8 ounces.
a) How many 2/3 -ounce doses can the veterinarian get out of one bottle of vaccine?
b) How many ounces of vaccine will be left in the bottle after she draws the maximum number of doses out?
Answer:
a) 5 1/3 ounces or 5.3333333333 ounces
b) 2 2/3 ounces or 2.67 ounces
Step-by-step explanation:
a) How many 2/3 -ounce doses can the veterinarian get out of one bottle of vaccine?
This is calculated as:
2/3 ounces of 1 bottle
2/3 ounces of 8 ounces
= 16/3 ounces
= 5 1/3 ounces or 5.3333333333 ounces
b) How many ounces of vaccine will be left in the bottle after she draws the maximum number of doses out?
This is calculated as:
8 ounces - 5 1/3
= 2 2/3 or 2.67 ounces

Shop 1 requires $260 down and a monthly payment of $20. Shop 2 requires $140 down and a monthly payment of $30. Write an equation to represent the payment plans where m is the number of months payments are made.
Answer:
Shop 1 = $260 + $20m
Shop 2 = $140 + $30m
Step-by-step explanation:
m = number of months payments are made
Total payment made = down payment + monthly payment
Shop 1 requires $260 down and a monthly payment of $20.
Shop 1 = $260 + $20m
= 260 + 20m
Shop 2 requires $140 down and a monthly payment of $30.
Shop 2 = $140 + $30m
= 140 + 30m
The equations that represent the payments plans are:
Shop 1 = $260 + $20m
Shop 2 = $140 + $30m
