Answer:
7/8
Step-by-step explanation:
1/4 times 2/2 = 2/8. you would have to do this because the only way you can add fractions is if they have the same denominator. so 2/8 + 5/8= 7/8
Answer:
You ate 7/8 of the chocolate bar.
Step-by-step explanation:
First, we need to change 1/4 and 5/8 so that they have the same denominators (bottom numbers).
There's a common multiple of 8.
What you do to the bottom needs to be done to the top.
1 x 8 = 8
1 x 5 = 5
5/8
Your amount of chocolate stays the same.
4 x 2 = 8
1 x 2 = 2
2/8 is how much the sister had,
Finally, add the two fractions together.
2/8 + 5/8 = 7/8
You ate 7/8 of the chocolate bar.
Hope this helps, have a good day! :D

Answer:
Step-by-step explanation:
put it on a coorinate grid,
circle circumference = 2*pi*r = 100.53
so the arc 19.2/100.53 = about 0.15 times the circumference of the circle
0.15*2pi = angle AOB in radians = 0.97
length DE is like 7.44
angle DOE is approx 0.485 radians beacuse it's half of angle AOB

Two friends race against each other in 100-meter and 800-meter races. Of the 200 races they ran this year, the wins, losses, and ties are shown below.
100 meter (Event D) 800 meter (Event E)
A won the race (Event A) 30 50
B won the race (Event B) 60 25
A and B tied (Event T) 10 25
B did not win the race today. What length of race was it more likely to have been? 100 meter or 800 meter? How much more likely?

A won the race (Event A) 30 50
B won the race (Event B) 60 25
A and B tied (Event T) 10 25
What percentage of all the races are ties?
If someone wins the race today, is it more likely for A to win or B to win? How much more likely?
Answer:
Its a long answer.........
Let makes the table neater. event D= 100m, even E=800m
(Event D) (Event E)
A won the race (Event A) 30 50
B won the race (Event B) 60 25
A and B tied (Event T) 10 25
B did not win the race today. What length of the race was it more likely to have been? The question is asking in what event did the chance of B did not win(lose + ties) is more likely. Then, you need to determine the chance for B did not win in both race.
Chance of B did not win 100-m= 30+10/10=40%
Chance of B did not win 800-m= 50+25/10=75%
The difference would be 75%-40%=35% more likely to lose 800-m race
________________________________
1. What percentage of all the races are ties?
IfThe chance for the race become tie is 10% for 100m and 25% for 800m. Assuming that the 200 race is divided equally, then there would be 100 race of 100-m and 100 race of 800-m.
The number of the event of ties would be:
(100*10% + 100*25%)/ 200= 35/200= 17.5%
__________________________________
2. If someone wins the race today, is it more likely for A to win or B to win? How much more likely?The event should be independent because the two events should not influence each other. That means the probability will not change and no one becomes more likely to win the next race.

The rectangular floor of a classroom is 32 feet in length and 36 feet in width. A scale drawing of the floor has a length of 8 inches. What is the perimeter, in inches, of the floor in the scale drawing?
Answer:
34
Step-by-step explanation:
32 / 8 = 4
36 / 4 = 9
perimeter of rectangle = 2(Length) + 2(width)
P = 2(8) + 2(9)
P = 16 + 18
P = 34

D. T= 4n-3
Answer:
C. T = 4n+6/2
Step-by-step explanation:
4n = 2(T-3)
or, 4n = 2T-6
or, 4n + 6 = 2T
or, 4n + 6 / 2 = T

for SPECIAL RIGHT TRIANGLES specifically a 30°-60°-90° triangle.
The longest side is the hypotenuse. The longest side is twice the shortest side. Or the other way around, the shortest side is half the longest side.
Here the longest side (hypotenuse) is 12, so the shortest side is 6.
Also, since you seem to be trying to get this subject.

5x + 15 = 55
5x = 40
x = 8
Correct Answer: B, 40
Hope this helps!
Answer:
x = 8
Step-by-step explanation:
Reorder the terms:
15 + 5x = 55
Solving
15 + 5x = 55
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = 55 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = 55 + -15
5x = 55 + -15
Combine like terms: 55 + -15 = 40
5x = 40
Divide each side by '5'.
x = 8
f(x)=2x+1/x-1 then f^-1(1)
Answer:
f⁻¹(x) = (x + 1) / (x - 2)f⁻¹(1 ) = - 2Step-by-step explanation:
Given function:
f(x) = (2x + 1) / (x - 1)Find its inverse, substitute x with y and f(x) with x, solve for y:
x = (2y + 1) / (y - 1)x(y - 1) = 2y + 1xy - x = 2y + 1xy - 2y = x + 1y(x - 2) = x + 1y = (x + 1) / (x - 2)Substitute y with f⁻¹(x):
f⁻¹(x) = (x + 1) / (x - 2)Find f⁻¹(1 ):
f⁻¹(1 ) = ( 1 + 1) / (1 - 2) = 2 / - 1 = - 2Factor completely. If the polynomial is not favorable, write prime.

Explain this, "Invest what you can afford to lose"
Answer:
If you lost something that you can't afford to lose, then it would greatly affect you. If you lost something that you can get again, then it wouldn't be as bad but it still would affect you. Say you invested your money into buying 30 stocks, each stock costed 12 dollars, and the next day it went down to 11.5. You only lost 15 dollars total. But if you spent your money on more stocks, you would have lost more money.
Clare is cycling at a speed of 12 miles per hour. I she starts at a position chosen as zero, what will her position be after 45 minutes?
Answer:
60÷12=0.2
0.2miles per minute
0.2x45=9miles
Answer:
9 miles
Step-by-step explanation:
The speed of 12 miles per hour means that for every hour, Clare is 12 miles further from the starting point.
1 hour ----- 12 miles
Since an hour is equivalent to 60 minutes,
60 mins ----- 12 miles
We can divide both sides by 60 to find the distance travelled per minute.
1 min ----- 12 ÷60= 0.2 miles
Multiply both sides by 45 to find the distance travelled in 45 minutes:
45 mins ----- 0.2(45)= 9 miles
Given that the starting position is at zero, Clare's position is at 9 miles after 45 minutes.

Answer:
One solutionKind Note:
This question is incomplete. You need to provide the question in order to get the best answer on brainly. In this answer, I will tell you how many solutions are in this system of equations.
Step-by-step explanation:
This question involves the use of 'system of equations'.
=> 4x + 10y = 2-4x + 8y = 16
=> (4x - 4x) + (10y + 8y) = (2 + 16)=> 18y = 18=> y = 1 (No further check required)Since the y-intercept is valid, the system of equations has one solution.
Hence, this system of equations has one solution.

What remainder is represented by the synthetic division below? A vertical line and horizontal line combine to make a L shape. There are two rows of entries within the shape. Row 1 has entries 2, 10, 1, 5. Row 2 has entries blank, negative 10, 0, negative 5. Entry negative 5 is on the outside to the left of the shape, and a third row of entries is outside and below the shape. Row 3 has entries 2, 0, 1, 0. –5 0 1 2.
The remainder represented by synthetic division is -5.
GivenA vertical line and a horizontal line combine to make an L shape.
There are two rows of entries within the shape.
Row 1 has entries 2, 10, 1, 5.
Row 2 has entries blank, -10, 0, -5.
What is synthetic division?Synthetic division can be defined as a simplified way of dividing a polynomial with another polynomial equation of degree 1.
Entry -5 is on the outside to the left of the shape.
The entry represents the zero of the divisor.
This entry to the variable (assume the variable is x) is;
[tex]\rm x=-5\\\\x+5=0[/tex]
Hence, the divisor of the synthetic division is -5.
