Answer:
scale = ½
center = (2, -5)
Step-by-step explanation:
The distance between A and B is 8
The distance between A' and B is 4
therefore the dilation scale factor is 4/8 = ½
As B and B' have the same x value, the center must also have the same x value of 2
The y value for A is -1
The y value for A' is -3
IF the y value for the center is Y
½(Y - (-1)) = (Y -(-3))
½(Y + 1) = (Y + 3)
½Y + ½ = Y + 3
-2.5 = ½Y
Y = -5
The factory produces 770 gaskets per hour
<h3><u>Solution:</u></h3>
Given that, A factory produces gaskets at a constant rate
After 6 hours 4620 gaskets have been produced
<em><u>To find: Gaskets produced by factory per hour</u></em>
We have been given that 4620 gaskets is produced in 6 hours. So in one hour number of gaskets produced can be found by dividing 4620 by 6
![\text { Number of gaskets produced in } 1 \text { hour }=\frac{4620}{6}=770](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Number%20of%20gaskets%20produced%20in%20%7D%201%20%5Ctext%20%7B%20hour%20%7D%3D%5Cfrac%7B4620%7D%7B6%7D%3D770)
So per hour, 770 gaskets are produced
<em><u>Verification:</u></em>
Gaskets produced in 6 hours = 6 x number of gaskets produced per hour
Gaskets produced in 6 hours = 6 x 770 = 4620
Hence our solution is correct
Answer: Choice D) earns 5 times as many points compared to previous level
Reasoning:
Let's say she's at level x = 1. That means she earns y = 5^x = 5^1 = 5 points.
At level x = 2, she earns y = 5^x = 5^2 = 25 points
When x = 3, we have y = 5^x = 5^3 = 125 points
And so on. Each new level earns her 5 times as many points as the previous level.
Not sure but I think
a) 4/6 which is 66.67%
b) 2/6 which is 33.33%
c) 4/6 which is 66.67%
i haven’t even finished high school so please don’t blame me if im wrong I do think that is the answer
Because an equivalent decimal names the same amount as another decimal. the 0 has no value
