Answer:
C
Step-by-step explanation:
The answer would be C because dilation ( unless by 1 ) doesn't preserve congruence so every other answer that isn't dilation would be right and C would be the answer because the factor is 2 not 1.

6. Place your work for both Part A and B in the space provided.
Part A: Select the option that best fits the scenario.
Gloria earned $400. She needed $320 for a new Chromebook.
What percent of the amount earned is the amount needed?
Which is the correct expression of this situation? (a or b)
a) 400 is what percent of 320?
b) 320 is what percent of 400?
Part B: Show your work to find the percent.
9514 1404 393
Answer:
A: (b) 320 is what percent of 400
B: 80%
Step-by-step explanation:
Part A:
This is a reading comprehension question. You are told that ...
$320 is the amount needed
$400 is the amount earned
and you are asked to find ...
what percent of the amount earned is the amount needed?
The question can be rephrased as ...
the amount needed is what percent of the amount earned?
Filling in the amounts you are told, the rephrased question becomes ...
$320 is what percent of $400 . . . . . matches choice (b)
__
Part B:
If we let x represent "what percent", then we can write the above question as ...
320 = x · 400
Dividing by 400 gives ...
320/400 = x = 0.80 = 80%
That is, 320 is 80% of 400.

Apply Newton’s method to estimate the solution of x3 − x − 1 = 0 by taking x1 = 1 and finding the least n such that xn and xn + 1 agree to three digits after the decimal point.
Solution :
Given
[tex]$f(x)=x^3-x-1, x_1=1$[/tex]
[tex]$f'(x)=3x^2-1$[/tex]
Let the initial approximation is [tex]$x_1 =1$[/tex]
So by Newton's method, we get
[tex]$x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)},n=1,2,...$[/tex]
[tex]$x_2=x_1-\frac{f(x_1)}{f'(x_1)}=1-\frac{1^3-1-1}{3(1)^2-1}=1.5$[/tex]
[tex]$x_3=1.5-\frac{(1.5)^3-1.5-1}{3(1.5)^2-1}=1.34782608$[/tex]
[tex]$x_4=1.34782608-\frac{(1.34782608)^3-1.34782608-1}{3(1.34782608)^2-1}=1.32520039$[/tex]
[tex]$x_5=1.32520039-\frac{(1.32520039)^3-1.32520039-1}{3(1.32520039)^2-1}=1.32471817$[/tex]
[tex]$x_6=1.32471817-\frac{(1.32471817)^3-1.32471817-1}{3(1.32471817)^2-1}=1.32471795$[/tex]
[tex]$x_5 \approx x_6$[/tex] are identical up to eight decimal places.
The approximate real root is x ≈ 1.32471795
∴ x = 1.32471795

What is 25 percent of 200?
What is 50 percent of 600?
Answer:
Step-by-step explanation:
50,300
Answer:
1. 50, 2. 300
Step-by-step explanation:
For 25 of 200, we can duplicate 100 and 25, which would turn out to be 50 and 200.
For 50 and 600, we can divide 600 by 2 to get 50 percent of it.
Answers:
25 of 200 = 50
50 of 600 = 300

Answer:
C. and E.
Step-by-step explanation:
Complimentary angles are two angles that both measures create the same degree as a right angle, or 90 degrees
Looking at the graph, we see 1 right angle, which is 9. Therefore we can cross out any answer that includes <9 in it.
Let's look at 7, this is an obtuse angle, WAY more than 90 degrees, therefore we can cross out any answer that includes <7 in it.
Meaning we only have three exceptable degrees, <6, <5, and <8.
There are only 2 answers that follow these rules. C and E
Allyson walked 10.8 km to the school. If 1 mile = 1.6 km, about how many miles did she walk?
Answer:
According to my calculations, 1.6 goes into 10.8 a total of 6 times with a remainder of 1.1999999999999993. If you continue the long division beyond the decimal point, the result would be 6.75.
Step-by-step explanation:
Answer:
6.75 miles
Step-by-step explanation:
1.6 km = 1 mile
1 km = 1/1.6 mile
10.8 km = [tex]\frac{1}{1.6}*10.8[/tex]
= 6.75 miles

Marta’s customer bought 4 large oranges at $0.75 each and 8 small oranges at $0.50 each plus tax was a total of $7.49. She used t to represent the amount of tax. Explain her errors in the diagram.
A bar diagram. The top box contains t. The bottom 3 boxes contain 7.49, 0.75 (8), and 0.50 (4).
Answer:
T should not have been in the top box the top box should have had 7.49 in it
Answer:
The total, 7.49, should be the top bar, and the variable, t, should be one of the partial bars. The prices for a certain number of oranges is also incorrect. $0.75 should be multiplied by 4 and $0.50 multiplied by 8.
