Answer:
[tex]\frac{17}{25}[/tex]
Step-by-step explanation:
So because it is a repeating decimal we have to round it off first. We can round it to the nearest hundredth making it 0.68. This then becomes [tex]\frac{68}{100}[/tex] as a fraction which can be reduced to its lowest terms by dividing both the numerator and denominator by 4 and then it becomes [tex]\frac{17}{25}[/tex].

Select one:
a.
whole numbers
b.
irrational numbers
c.
integers
d.
rational numbers
Answer:
b.
Step-by-step explanation:
30×0.5×63 = 945
this is not a square number. therefore, the sqrt(945) is a number of infinite digit positions after the decimal point without repeating pattern.
so, it is a prime example of an irrational number.

Simplify 4^2 ⋅ 4^8.
A)4^16
B)4^10
C)1^616
D)1^610
You will get 27pts if you answer this!!!
Answer:
4^2 * 4^8 = B)4^10
Step-by-step explanation:
When multiplying numbers with exponents, you will always add the exponents together. Therefore, 2+8=10 which is 4^10. You can also simplify the numbers and multiply them together. For example, 4^2=16 and 4^8=65,536 and when u multiply those numbers you get 1,048,576. The one that matches is 4^10=1,048,576.

given xz with x(1,9) and z(5,-11) if y lies on xz such that the ratio of xy to xz 1:4, find the coordinates of y
If a segment XZ joining two endpoints X[tex](x_1,y_1)[/tex] and Z[tex](x_2,y_2)[/tex] is divided by a point Y(x, y) externally in the ratio of m : n,
Coordinates of the point will be,
x - coordinates → [tex]\frac{mx_2-nx_1}{m-n}[/tex]
y - coordinates → [tex]\frac{my_2-ny_1}{m-n}[/tex]
If the coordinates of the endpoints X and Z are (1, 9) and (5, -11) respectively and the ratio in which a point Y divides the segment is 1 : 5,
(Since, XY : XZ = 1 : 4 therefore, XY : YZ = 1 : 5)
Therefore, coordinates of Y will be,
x- coordinates → [tex]\frac{1(5)-5(1)}{1-4}=0[/tex]
y-coordinates → [tex]\frac{1(-11)-5(9)}{1-5}=\frac{-56}{-4}=14[/tex]
Therefore, coordinates of Y will be [tex](0,14)[/tex].

Solve the equation for the indicated variable.
y(a-b)=c(y+a);y
Answer:
y = [tex]\frac{ac}{a-b-c}[/tex]
Step-by-step explanation:
Given
y(a - b) = c(y + a) ← distribute parenthesis on both sides
ay - by = cy + ac ( subtract cy from both sides )
ay - by - cy = ac ← factor out y from each term on the left side
y(a - b - c) = ac ← divide both sides by a - b - c
y = [tex]\frac{ac}{a-b-c}[/tex]
The value of y is ac/ (a-b-c)
What is an equation?An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.
For example, 3y = 16 is an equation.
Given equation:
y(a-b)=c(y+a)
Now, using distributive property
ay-by = cy + ac
ay-by-cy = ac
y(a-b-c)=ac
y= ac/ (a-b-c)
Hence, the value of y is ac/ (a-b-c).

Temperature at 9 am = 4° F

A store is having a sale on CDs. Adrian buys five CDs and spends $40. If he decides to go back to the sale, and buy two more CDs, how much will he pay? How much with he pay for eight CDs?
Answer:
If Adrian buys 2 more CDs, he will pay $56.
Adrian will pay $64 for eight CDs.
Step-by-step explanation:
So, we already know that 5 CDs costs $40. That means that we can use this information to figure out how much 1 CD costs.
40 ÷ 5 = $8 per CD
Now that we know that each CD costs $8, we know that if Adrian buys 2 more CDs, then he will pay $16 ($8 x 2) more than his current price.
$40 + $16 = $56.
If Adrian buys 2 more CDs, he will pay $56.
Now, in order to find out how much 8 CDs costs, we just need to divide $8 by 8.
$8 x 8 = $64
Therefore, Adrian will pay $64 for eight CDs.
I hope this helps! :)

How long did Kajal speak on the phone?
Answer:
1 hour and 29 minutes
Step-by-step explanation:
4:50 pm to 6:00 pm is 1 hour and 10 minutes.
6:00 pm to 6:19 pm is 19 minutes.
1 hour and 10 minutes + 19 minutes = 1 hour and 29 minutes.
Explanation:
Let's find out how long Kajal spoke on the phone.
4:50 + 10 mins = 5:00
5:00 + 60 mins = 6:00
6:00 + 19 mins = 6:19
To find the total time between 4:50 + 6:19, we add the distances.
10 mins + 60 mins + 19 mins = 89 mins
Thus, Kajal spoke on the phone for 89 minutes.

Answer:
y=3
Step-by-step explanation:
6=2(y+2)-4
6=2y+4-4
6-4+4=2y
6=2y
3=y
The answer you are looking for is y=3.
Solution/Explanation:
First, writing out the problem,
6=2(y+2)-4.
Next, using the Distributive Property for 2(y+2), which is 2y+4,
6=2y+4-4.
Now, canceling out the 4, since 4-4=0,
6=2y+0, or 6=2y.
Finally, dividing both sides by 2,
6/2=2y/2.
6/2=3.
2y/2=y.
3=y, or y=3.
So, therefore, the final answer is y=3.
I hope that this has helped answer your question. Good day to you.
