Answer:
Sandhya performed better.
Step-by-step explanation:
You can either or simplify the fractions:
[tex]\frac{630}{900}[/tex] and [tex]\frac{650}{1300}[/tex] to simpler forms like [tex]\frac{7}{10}[/tex] and [tex]\frac{1}{2}[/tex] from there you can make the [tex]\frac {1}{2}[/tex] and multiply it by [tex]\frac{5}{5}[/tex] to get [tex]\frac{5}{10}[/tex] and then from there you can see Sandya performed better.
OR
You can divide 630 by 900 and 650 by 1300
630/900 gives you 70
and
650/1300 gives you 50
Clearly, once again Sandhya performed better.

The point Q(-6, 3) is reflected over the y-axis. What are the coordinates of the resulting
point, Q'?
Answer:
Q' = (6,3)
Step-by-step explanation:
You can think of this problem in two ways:
Graph:
I've shown my working for this, where I've counted how many units it takes to get from point Q to the axis through which im reflecting. There are 6 units between Q and the y axis, so naturally there should be 6 units between Q' and the y axis.
Coordinates:
Since this is a reflection through an axis, we can assume that the the x coordinate of point Q' will be equal and opposite to Q. Therefore, while the x coordinate of Q was -6, of Q' it's 6

a. Start with: 60
Rule: Increase by 20%
60 , 72, ?, ?, ?
Answer:
60, 72, 86.4, 103.68, 124.42
Step-by-step explanation:
How do I add 20% to a number?
Divide the original number by 100 to get 1% of it.
Multiply 1% by your desired percentage, in this case 20.
Add the product of the previous step to your original number.
Congratulate yourself on adding 20% to your number!
Answer:
60, 72, 86.4, 103.68, 124.416, ...Step-by-step explanation:
Given sequence:
60, 72, ...The rule is adding 20%
Adding 20% is converted to common ratio:
x + 20% =120% of x =1.2xThe sequence is the GP with common ratio of 1.2:
60, 72, 72*1.2= 86.4 , 72*1.2² = 103.68 , 72*1.2³ = 124.416Write the slope-intercept form of the equation of the line through the given points.
through: (5,1) and (1, -3)
Answer:
y = x-4
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -3 -1)/( 1 - 5)
= -4/-4
= 1
Then using slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 1x+b
Substitute one of the points in
1 = 5 +b
1-5 = b
-4 =b
y = x-4

Answer:
the third expression
Step-by-step explanation:
x=10.8
(x2 / 18) + 33.52
10.8 x 10.8=116.64
116.64 divide by 18=6.48

If you roll a fair 6 sided die and then roll a second fair what is the probability that you roll 1, 2, or 3 on the first die and roll 5 on second
Given:
A fair 6 sided die is rolled and then a second fair die is rolled.
To find:
The probability that you roll 1, 2, or 3 on the first die and roll 5 on second.
Solution:
If two fair die are rolled, then the total possible outcomes are
S= {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)}
So, total outcomes = 36.
Favorable outcomes of getting 1, 2, or 3 on the first die and roll 5 on second are (1,5), (2,5), (3,5).
So, favorable outcomes = 3
We know that
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{3}{36}[/tex]
[tex]\text{Probability}=\dfrac{1}{12}[/tex]
Therefore, the required probability is [tex]\dfrac{1}{12}[/tex].

What are the solutions to the system of equations?
x^2 + y^2 = 5
y = 2x
The solution with the smaller x value is (?)
The solution with the larger x value is (?)
Answer:
(- 1, - 2 ) and (1, 2 )
Step-by-step explanation:
Given the 2 equations
x² + y² = 5 → (1)
y = 2x → (2)
Substitute y = 2x into (1)
x² + (2x)² = 5
x² + 4x² = 5
5x² = 5 ( divide both sides by 5 )
x² = 1 ( take the square root of both sides )
x = ± [tex]\sqrt{1}[/tex] = ± 1
Substitute these values into (2) for corresponding values of y
x = - 1 : y = 2(- 1) = - 2 ⇒ (- 1, - 2 )
x = 1 : y = 2(1) = 2 ⇒ (1, 2 )
The solution with smaller x- value is (- 1, - 2 )
The solution with the larger x value is (1, 2 )
A garden table and a bench cost $935 combined. The garden table costs $85 more than the bench. What is the cost of the bench?
Answer:
The bench costs $425
And the Table costs $510
Step-by-step explanation:
table + bench = $ 935
$85 + 2b = $935
$935 - $ 85 = $ 850
$850/ 2 = 425 = b

What are the domain and range of the function f(x)=square root x-7 +9?
Answer:
Domain is all real numbers greater than or equal to 7. Range is all real numbers greater than or equal to 9.
Step-by-step explanation:
The domain is possible x-values while the range is possible y-values. This question look like
[tex] \sqrt{x - 7} + 9[/tex]
The domain of square root function cant have a the radical inside being a negative number because we can't take the sqr root of a negative number and graph it on a cartisean plane We can take the sqr root of 0 . So we set x-7=0. And which x=7 so the domain is all real numbers that are equal to or greater than 7. The range of a sqr root function can only yield any positive y-values. So we must find the lowest point of it. Since the lowest x value we can possible use is 7 we plug it in
[tex] \sqrt{7- 7} + 9[/tex]
which equals 9. So the range is all real numbers greater than or equal to 9.

To travel to school, Gavin must walk to the bus stop. The bus trip covers
four times the distance that he walks. He then needs to walk 500 m to
school. If the school is 10 km away from Gavin's home, how far does he
walk to the bus stop?
Answer:
2,375 m
Step-by-step explanation:
The computation of the distance from his walk to the bus stop is given below:
Let us assume he walks be x
So the bus trip be 4x
4x + 500m
From Home to school, it would be 10km
As we know
1km = 1000m
So for 10km it would be = 10,000 m
4x + 500 m = 10,000 m
4x = 10,000 m - 500 m
4x = 9,500 m
x = 2,375 m

There are 42 girls and 56 boys who want to play a game. Each team will have both boys and girls on it. The ratio of boy to girls has to be the same for each team. Everyone must participate in the game. What is the greatest number of teams that can be formed?
Answer:
7 teams with 6 girls and 8 boys on each team
Step-by-step explanation:
Both 42 (girls) and 56 (boys) are divisible by 7 (getting 6 and 8).
Therefore, there would be 6 girls and 8 boys on each team.
The ratio would be 6 girls:8 boys per team.
Check:
6•7=42 ––(6 girls amongst 7 teams = 42 girls total)
8•7=56 ––(8 boys amongst 7 teams = 56 boys total)
Billy Bob bench presses 200 lbs. He wants to bench more than 300 lbs. If he improves by 20 lbs a month how long will it take him to bench over 300 lbs.
Write your answer like x>3 make sure you use the right sign.
WILL GIVE BRAINLIEST
it will take him 5 months
Find how much more he wants to bench:
300-200 = 100
He needs to increase by at least 100 pounds.
So 20 pounds per month has to be greater than 100 pounds.
20x > 100
Divide both sides by 20:
X > 5 months

5x – 2x = 12
How do I solve
Answer:
4
Step-by-step explanation:
Replace X with 4
(5*4)-(2*4) = 12
Answer:
x =4
Step-by-step explanation:
5x - 2x =12 (Subtract 5x - 2x and you'll get 3x)
3x = 12 (Now divide by 3 from both sides to get x)
x = 12/3 (Now that you got x, you want to simplify)
x = 4 (12 divided by 3 is 4)

Answer:
16
Step-by-step explanation:
because it is
Answer: 16
Step-by-step explanation: Here's a little tip for you. Any number can be converted to a fraction if you use 1 as the denominator:
64/1
So now that we've converted 64 into a fraction, to work out the answer, we put the fraction 1/4 side by side with our new fraction, 64/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:
1x64/4x1 = 64/4
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers:
The GCF of 64 and 4 is 4.
We can now divide both the new numerator and the denominator by 4 to simplify this fraction down to its lowest terms:
64/4 = 16
4/4 = 1
When we put that together, we can see that our complete answer is:
16/1
The complete and simplified answer to the question what is 1/4 of 64 is:
16
Hopefully, this tutorial has helped you to understand how to find the fraction of any whole number. You can now go give it a go with more numbers to practice your newfound fraction skills.
