what is the answer to 15 and 18? pls help it will mean a lot:)
Answer and Step-by-step explanation:
15. [tex]-\frac{27}{20}[/tex] or [tex]-1\frac{7}{20}[/tex]
-1.35 = -135/100 = [tex]-1\frac{35}{100}[/tex] (Mixed number)
Multiply the number by 100, then divide the number by 100 (but keep it in fraction form).
-1.35 x 100 = -135
[tex]-\frac{135}{100}[/tex] = [tex]-\frac{27}{20}[/tex]
(Mixed Fraction = . To check, multiply the 20 by the 1, then add 7, to get -27/20)
18. [tex]\frac{49}{11}[/tex] or [tex]4\frac{5}{11}[/tex]
4.45 = 49/11 = [tex]4\frac{5}{11}[/tex]
4.4545.....
Multiply the number by 100 (because there is 2 numbers being repeated.
445.4545....
Now subtract by the original number.
445.4545....
- 4.4545....
441.00
Write this as an equation:
(100 x fraction) - fraction = 441 (100 x fraction) - fraction = 99 x fraction
99 x fraction = 441 (Divide both sides by 99)
fraction = [tex]\frac{441}{99}[/tex] (which simplifies down to [tex]\frac{49}{11}[/tex])

In 2015, 120000 people voted. The number of viewers who voted in 2015 was 20% more than those in 2014. Calculate the numbers of viewers who voted in 2014
Answer:
Given;
120,000 people voted in 2015.
In 2015, 20% more people voted than 2014.
Therefore:
How many more people voted in 2015 = 20% of 120,000
= 24,000
Total number of people voted in 2014 = 120,000 - 24,000
= 96,000
Ans) 96,000 people voted in 2014.
Martin spent $300 from his savings account on a new bike. He also deposited $300 in his savings account that he earned from selling his used textbooks. Which integer represents the change in Martin's savings? A) $100 B $0
C. -100$ D. -$200
Answer:
B
Step-by-step explanation:
a money account works in the same way as real things we can touch.
so, when I have 300 apples at a place (e.g. a grocery store), then I take away 300 apples, and then put again 300 apples there - how many apples will be there at that moment ?
we had 300 and took away 300.
300 - 300 = 0
at that moment we have 0 apples.
but then we put again 300 apples there.
0 + 300 = 300
so, we end up with 300 apples. the same number we started with.
and the same way for the savings account.
he takes out $300.
that means he has now $300 less on his account.
and then he adds $300.
so, he added exactly the same amount as he took out earlier, which means nothing else than that he undid his earlier action regarding his bank account.
so, his balance is now exactly the same as before he did the first transaction.
therefore the change is exactly : $0

Step-by-step explanation:
How to find the absolute value of |2x+3|=13
Answer:
x=5 or x = -8
Step-by-step explanation:
|2x+3|=13
There are two solutions to this problem, one positive and one negative
2x+3 =13 and 2x+3 = -13
Subtract 3 from all sides
2x+3-3 = 13-3 2x+3-3 = -13-3
2x = 10 2x = -16
Divide each side by 2
2x/2=10/2 2x/2 = -16/2
x = 5 x = -8
If a1=1. And r=1/5 find a8
Answer:
a₈ = [tex]\frac{1}{78125}[/tex]
Step-by-step explanation:
The nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
Here a₁ = 1 and r = [tex]\frac{1}{5}[/tex] , then
a₈ = 1 × [tex](\frac{1}{5}) ^{7}[/tex] = 1 × [tex]\frac{1}{78125}[/tex] = [tex]\frac{1}{78125}[/tex]

What is the slope of the line containing (–1, 8) and (3, –12)? A. 5 B. – C. –5 D.
Answer:
-5
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
=(-12 -8)/(3 - -1)
=(-12-8)/(3+1)
= -20/4
= -5
Thomas has 3 boxes, each with 8 balls.
He wants to place the balls evenly into 4 boxes.
How many balls will be in each of the 4 boxes?
Answer: 6 balls will be in each of the 4 boxes.
Step-by-step explanation:
Multiply 3x8 to find out how many balls there are total.
3x8=24
Then to split them evenly, you divide by 4 (the amount of boxes they are split into)
24/4= 6
Find the distance between the ponits.
(-3, -6) and (3, x6)
Help please
Step-by-step explanation:
Hey there!
The given points are: (-3,-6) and (3,-6).
x 1 = -3 y1 = -6
x 2 = 3 y2 = -6
Use distance formula;
[tex]d = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} } [/tex]
Keep all the values;
[tex]d = \sqrt{( {3 - ( - 3))}^{2} + ( { - 6 - ( - 6))}^{2} } [/tex]
Simplify:
[tex]d = \sqrt{ {(6)}^{2} + {( - 6 + 6)}^{2} } [/tex]
[tex]d = \sqrt{ {(6)}^{2} } [/tex]
Therefore, the distance is 6 units.
Hope it helps!
kendra revived a bonus that was 30%of her monthly earnings is her monthly earnings were 930 how much was kendras bonus
Hey there! I'm happy to help!
30% is the same thing as 0.3 because 0.3 is 30% of 1. If you multiply something by 1, it will just stay the same, so you need that percent of 1.
To convert a decimal to a percent, you move the decimal to the left two spaces.
Now, we simply multiply this by 930.
0.3×930=279
So, Kendra will receive a bonus of $279.
Have a wonderful day and keep on learning! :D

To solve for WX, we have to find the length of the part of the line that isn't XY. Since we know the full length of the line, we subtract the length of XY from WY to get WX:
100-89.6
10.4
The length of WX is 10.4 centimeters.
I hope this was helpful, keep learning :D
Answer: WX = 10.4 cm
Concept:
Here, we need to know the idea of the segment addition postulate.
The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
Given information
XY = 89.6 cm
WY = 100 cm
Given expression deducted from the segment addition postulate
WX = WY - XY
Substitute values into the expression
WX = 100 - 89.6
Simplify by subtraction
WX = [tex]\boxed{10.4cm}[/tex]
Hope this helps!! :)

Find the last three digits of the sum A=11!+12!+13!+...+2006!
Answer:
996
Step-by-step explanation:
