Answer:
Scale factor = 4
Step-by-step explanation:
Scale factor = [tex]\frac{\text{Dimension of the larger (Image) triangle}}{\text{Dimension of the smaller (Preimage) triangle}}[/tex]
From the given triangle,
Length of one side of the larger triangle = 8 units
Length of the corresponding side of the smaller triangle = 2 units
By substituting the values in the formula of scale factor,
Scale factor = [tex]\frac{8}{2}[/tex]
Scale factor = 4
Tom needs to plow 1.1 acres of land. If he can plow 5.5 acres in an hour, how many hours will it take?
Help! (16 pts if you answer!)
Given:
Tom needs to plow 1.1 acres of land.
He can plow 5.5 acres in an hour.
To find:
The time taken by Tom to plow 1.1 acres of land.
Solution:
We have,
Time take by Tom to plow 5.5 acres = 1 hour
Time take by Tom to plow 1 acre = [tex]\dfrac{1}{5.5}[/tex] hour
Time take by Tom to plow 1.1 acres = [tex]\dfrac{1.1}{5.5}[/tex] hour
= [tex]0.2[/tex] hour
Therefore, the time taken by Tom to plow 1.1 acres of land is 0.2 hour.

How do you find the value of x in the triangle?
To find the value of x in a triangle, you need to subtract the sum of the two angles from 180 degrees. Know that the sum of all the angles of a triangle will always equals 180 degrees. Then write down the difference of subtracting the sum of the two angles from 180 degrees and that would equal the value of x.

Answer:
Negative
Step-by-step explanation:
On the line, we see that a = 0.5 and b is after -1. a + b will be negative because anything after -1 added to .5 will be negative.
Example:
-1 + .5 = -.5
-2 + .5 = -1.5
-3 + .5 = -2.5
Answer: Negative
Step-by-step explanation: the b we can see is far away from -1 that means its around - 2 and if we were to add 0.5 and - 2 we would get -1.5

Answer:
The m∠YXW is 125°.
Addition equation: m∠YXW = m∠YXZ + m∠ZXW = 85° + 40° = 125°
Step-by-step explanation:
To find the m∠YXW you would need to add the m∠YXZ and m∠ZXW together:
m∠YXW = m∠YXZ + m∠ZXW = 85° + 40° = 125°

If m∠RQS=22x-11 and m∠RQT=12x-8, find m∠TQS
Answer:
∡TQS = 10x -3
Step-by-step explanation:
∡TQS = ∡RQS - ∡RQT
= 22x - 11 - (12x - 8)
= 10x -3

PLS HELP Choose the solution to this inequality. 43<−83y y < −12 y > 12 y < 43 y > 4
Given:
The inequality is:
[tex]\dfrac{4}{3}<-\dfrac{8}{3}y[/tex]
To find:
The solution of the given inequality.
Solution:
We have,
[tex]\dfrac{4}{3}<-\dfrac{8}{3}y[/tex]
Multiply both sides by 3.
[tex]4<-8y[/tex]
Divide both sides by -8 and change the sign of inequality.
[tex]\dfrac{4}{-8}>\dfrac{-8y}{-8}[/tex]
[tex]-\dfrac{1}{2}>y[/tex]
It can be written as:
[tex]y<-\dfrac{1}{2}[/tex]
Therefore, the correct option is A.
