You are drawing a map of your school and want to make sure all the measurements are accurate. You decide to use a scale of 1 cm = 3 feet. In your drawing, the main hallway ends up being 12 cm long.
The drawing is a little too big so you decide to change the scale to 1 cm = 4 feet.
Keeping the length in feet the same, how many centimeters long should the main hallway be in your new drawing?
Answer:
the main hallway should be 12cm in the new drawing

Answer:
7u -63
Step-by-step explanation:
The distributive property says you can eliminate parentheses by applying the outside factor to each term inside parentheses.
(u -9)7 = (u)(7) +(-9)(7) = 7u -63
Answer:
(u -9)7 = (u)(7) +(-9)(7) = 7u -63

ME NEED HELP HERE SO CONFUSED
Answer:
106°
Step-by-step explanation:
By exterior angle theorem:
[tex]m \angle \: 1 = 62 \degree + 44 \degree \\ \\ m \angle \: 1 = 106 \degree[/tex]
Step-by-step explanation:
Let the unknown angle in the triangle be x.
x + 44 + 62 = 180(sum of angles in a triangle)
x + 106 = 180
x = 180 - 106
x = 74
Angle 1 + x = 180 (Sum of angles on the same straight line)
angle 1 + 74 = 180
Angle 1 = 180 - 74
= 106

What’s the length of a segment whose endpoints are (8,-6) and (-4,2)?
Answer:
Step-by-step explanation:
Imagine or draw a triangle with horizontal leg length 8 - (-4), or 12, and vertical leg length |-6 - 2|, or 8. Use the Pythagorean Theorem to find the length of the hypotenuse:
length of hypotenuse = +√(8² + 12²) = √208 = 4√13 (Answer A)

Answer:
Add 3 after multiplying 1 and x.
Step-by-step explanation:
In this question we have to convert the given algebraic expression into a verbal expression.
Given algebraic expression is,
y = x + 3
Here, x is multiplied by 1
And 3 is added to x.
Therefore, verbal expression or statement will be,
Add 3 after multiplying 1 and x.
This rule defines the relationship between x and y.

Find x
a(21)
b(27)
c(9)
d(18)
9514 1404 393
Answer:
a. 21
Step-by-step explanation:
The external part of the hypotenuse of the right triangle is shown. The full length of the hypotenuse is 9+20 = 29. The Pythagorean theorem can be used to find x.
x^2 +20^2 = 29^2
x^2 = 841 -400
x = √441
x = 21
__
Alternate solution
The diameter of the circle is 2·20 = 40 units, so the product of distances from the external vertex to the opposite sides of the circle along the secant is (9)(40+9). The product of the distances along the tangent is x·x. These two products are equal, so ...
x^2 = 9(49)
x = (√9)(√49) = 3·7
x = 21

It's Homework #1: Odds
Answer:
1/2 ; 7/10
Step-by-step explanation:
1) we have ten letters A, E, I, O, U are five letters, so the odd can be expressed with the fraction 5/10, that can be simplified in 1/2
2) we have 7 non black parts in a total of ten parts, so the odd is 7/10
After applying the distributive property to the expression 8(12-4) and then multiplying what will be the first term in the resulting subtraction expression
Answer:
The first term in the resulting subtraction expression is 96.
Step-by-step explanation:
Given - After applying the distributive property to the expression 8(12-4) and then multiplying
To find - What will be the first term in the resulting subtraction expression ?
Proof -
Given the expression is -
8( 12 - 4) = 8(12) - 8(4)
= 96 - 32
⇒8( 12 - 4) = 96 - 32
So,
The first term in the resulting subtraction expression is 96.
Calculate the area of the shape below:
6 in
6 in
12 in
O 54 in?
0 432 in?
O 216 in
O 108 in?
Answer:
54
Step-by-step explanation:
The square in the middle = 36, as 6x6=36
There are 2 triangles on each side of the center square.
Since the base of the trapezoid is 12, and the base of the square is 6, that leaves 3 for the base of each triangle.
3x6=18x1/2 (As a triangle's area is b (base) x h (height) x (one half) 1/2
18x1/2 is 9.
Each triangle equals 9.
36+9+9=54
The final answer is 54
The two legs of a right triangle measure 7 inches and 5 inches. Find the measure of the acute angle that is included between the longer leg and the hypotenuse. WILL GIVE BRAINIEST TO FIRST RIGHT ANSWER
Answer:
44.4 degrees
Step-by-step explanation:
Given the following
Hypotenuse = 7
Longer leg = 5 (adjacent])
Let the acute angle angle between both sides be x
According to SOH CAH TOA
Cos theta = adj/hyp
Cos x = 5/7
x= arccos (5/7)
x = arccos (0.7143)
x = 44.4degrees
Hence he measure of the acute angle that is included between the longer leg and the hypotenuse is 44.4 degrees
find the nth term of this quadratic sequence 4 9 16 25 36
Answer:
aₙ = n² + 2n + 1Step-by-step explanation:
a₁ = 4 = 2² = (1 + 1)²
a₂ = 9 = 3² = (2 + 1)²
a₃ = 16 = 4² = (3 + 1)²
a₄ = 25 = 5² = (4 + 1)²
a₅ = 36 = 6² = (5 + 1)²
Therefore:
aₙ = (n + 1)² = n² + 2n + 1
The ceiling of Katie’s living room is a square that is 15 ft long on each side. To decorate for a party, she plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner. Katie can buy rolls that each contain 20 ft of crepe paper. What is the minimum number of rolls she should buy? Show your work.
Answer:
6 rolls because the total perimeter is 102 ft and five rolls is only 100 feet. So she needs 6 rolls.
Step-by-step explanation:
to find perimeter, add up all the side lengths.
so 15*4 (it's easier than 15+15+15...)
60 ft.
now we have to use Pythagorean's Theorum to find corner to corner.
so [tex]a^2+b^2=c^2[/tex]
we have a and b
[tex]15^2+15^2=c^2[/tex]
do the math...
225+225= 450
square root of 450=
21.213
double that because it's used twice (corner to corner and corner to corner)
42.426
now add it all up
42.426 + 60 = 102.426
we can round
102
20*5 = 100
so she needs 6
MY ORIGINAL ERROR WAS 5, BUT 5 TIMES 20 IS ONLY 80, SO THEREFORE 6 IS REQUIRED SO THERE IS ENOUGH TO COVER 102.
Answer:
Katie needs 6 crepe rolls.
Step-by-step explanation:
Hello!
Katie originally needed ~5.1 crepe rolls, but since its a question on how many rolls she should by, she should get 6.
There are a couple of steps in order to solve this.

What’s the probability?
Answer:
[tex]\frac{1}{8}[/tex]
Step-by-step explanation:
The probability for a flip on either side of the coin is always 50% or [tex]\frac{1}{2}[/tex]
So to get the probability for the three flips just do:
[tex](\frac{1}{2}) ^{3}[/tex] or [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex]
Either way you solve it the answer is [tex]\frac{1}{8}[/tex]
