Quadrilateral A'B'C'D'is a rotation of quadrilateral ABCD 180° about the origin.
What is the length of A'B'?
A. 6 units
B. 7 units
C. 3 units
D. 4 units
Answers
Answer:
Answer- B, 7 units
Step-by-step explanation:
I took the quiz
A.P.E.X
The length of side A'B' is 7 units, so the correct option is B.
What is the length of A'B'?We know that the side length is invariant under rotations, that means that the equivalent sides of the preimage and the image have equal length, then:
AB = A'B'.
We can see that AB= 7, then we can conclude that the correct option is B.
A'B' = 7 units.

What are the points on y-axis which are at a distance of 4 units from 4x+3y=12
Answers
Given:
The equation of line is
[tex]4x+3y=12[/tex]
To find:
The points on y-axis which are at a distance of 4 units from the given line.
Solution:
The point lie on the y-axis. So, their x-coordinate must be zero.
Let the points are in the form of (0,k).
The distance between a point [tex](x_0,y_0)[/tex] and a line [tex]ax+by+c=0[/tex] is
[tex]d=\dfrac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}[/tex]
The given equation can be written as
[tex]4x+3y-12=0[/tex]
The distance between (0,k) and [tex]4x+3y-12=0[/tex] is 4 units.
[tex]4=\dfrac{|4(0)+3(k)-12|}{\sqrt{4^2+3^2}}[/tex]
[tex]4=\dfrac{|0+3k-12|}{\sqrt{16+9}}[/tex]
[tex]4=\dfrac{|3k-12|}{\sqrt{25}}[/tex]
[tex]4=\dfrac{|3k-12|}{5}[/tex]
Multiply both sides by 5.
[tex]20=|3k-12|[/tex]
[tex]\pm 20=3k-12[/tex]
[tex]12\pm 20=3k[/tex]
[tex]\dfrac{12\pm 20}{3}=k[/tex]
Now,
[tex]k=\dfrac{12-20}{3}\text{ and }k=\dfrac{12+20}{3}[/tex]
[tex]k=\dfrac{-8}{3}\text{ and }k=\dfrac{32}{3}[/tex]
Therefore, the two points are [tex]\left(0,\dfrac{-8}{3}\right)\text{ and }\left(0,\dfrac{32}{3}\right)[/tex].

A new phone costs $230 and the sales tax rate is 7%. What is the total cost of the camera after tax?
Answers
That's a question about percentage.
One way to represent percentage is using decimal number. In this way, 1 is equivalent to 100% and the other less percentages using numbers between 0 and 1.
Examples:
90% is equivalent to 0,90.5% is equivalent to 0.05. It's not 0.5 because 0.5 is equivalent to 50%.13.17% is equivalent to 0.1317.245% is equivalent to 2.45.If we want to know the percentage of a number, we should multiplacate the number by the porcentage in the decimal number form.
Examples:
55.90% of 200 is equal to: [tex]200 \times 0.5590 = 111.8[/tex]360% of 88 is equal to: [tex]88\times 3.6 = 316.8[/tex]In our problem, we have a phone with a increase of 7%. To solve that, it's important to perceive that $230 is equal to 100% and with a increase of 7%, we will pay 107%.
107% in the decimal number form is 1.07. With that information, we should multiplicate 1.07 by the original value and we will find the answer.
We know that [tex]230\times 1.07 = 246.1[/tex], therefore, the total cost of the phone after tax is $246.1.

Answer:

y=5
Answer:
x = 9
y = 5
Step-by-step explanation:
3x + y = 32...(1)
3x - 2y = 17....(2)
multiplying equation (1) by 2 we get,
6x + 2y = 64...(3)
Adding eq(2) and (3) we get,
6x + 2y = 64
+ 3x - 2y = 17
----------------------
9x. = 81
therefore, x = 81/9
therefore, x = 9
substituting value of x in eq( 1)
3 * 9 + y = 32
27 + y = 32
y = 32 - 27
y = 5

Six friends share 3/4 of a pound of roasted almonds. What fraction of a pound does each friend receive
Answers
Answer: 1/8 pounds of roasted almonds
Step-by-step explanation:
There are six friends and each of them are to receive and equal piece out of a 3/4 pound of roasted almonds.
The almonds each friend will get will therefore be the 3/4 pack divided by 6:
= 3/4 ÷ 6
= 3/4 * 1/6
= 3/24
= 1/8 pounds of roasted almonds
When dividing by a number, you can instead multiply by the inverse of that number.

Hence, value of y = 5.5.
Answer: y = 5 ½ or y = 5.5
Step-by-step explanation:
4y - 7 = 15
Add 7 to both sides of the equation.
4y = 22
Divide both sides by 4
y = 5.5
Substitute y in the original equation.
4(5.5) - 7 = 15

Determine how much you would receive in return for a 8 month, $500 loan to a friend if you charged the 3% annual interest.
Answers
Answer:
You would receive $510.08 in return.
Step-by-step explanation:
In order to find the answer, you can use the formula to calculate the future value:
FV=PV*(1+i)^n
FV=future value
PV= present value= 500
i= interest rate=0.03/12=0.0025 per month
n= number of periods of time= 8
Now, you can replace the values in the formula:
FV=500*(1+0.0025)^8
FV=500*(1.0025)^8
FV=510.08
According to this, the answer is that you would receive $510.08 in return.
