Answer:
The correct option is;
B. GT PT ET GV PV EV
Step-by-step explanation:
The given information we have;
The number mathematics topics Travis has to chose from tonight = 3 topics
The number of ways he can chose to study each topic = 2 ways
Therefore the number of different combo Travis can chose from is given as follows;
The number of combos = The number of topics × The number of ways
∴ The number of combos = 3 × 2 = 6 combos
Therefore, the possible combos are;
B. GT PT ET GV PV and EV which is the same as GT, GV, PT, PV, ET, and EV.

What is a circle?The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.
The minor arc is 75°. And the another arc is 130°.
We know that the complete circle subtends 360 degrees.
Then the measure of the major arc will be
Major arc + 130° + 75° = 360°
Major arc + 205° = 360°
Major arc = 155°
Then the value of the angle x will be given by the half of the difference of the major arc to minor arc.
x = (Major arc – minor arc) / 2
x = (155 – 75)/2
x = 80 / 2
x = 40°
Thus, the value of the angle x will be 40°.
Then the correct option is B.

Increase #500 in the ratio 16:10
Answer:
Answer is 900.
Step-by-step explanation:
To find:
Increase #500 in the ratio 16:10
Solution:
New Number: Old Number = 16:10
We are given the old number as 500.
Let the new number after increase = [tex]x[/tex]
Now, using the above ratio:
[tex]x[/tex]: 500 = 16:10
[tex]\dfrac{x}{500} = \dfrac{16}{10}\\\Rightarrow x = 500 \times \dfrac{16}{10}\\\Rightarrow x = 50 \times 16\\\Rightarrow x = 900[/tex]
Therefore, the increased value of 500 in the ration 16:10 is 900.
Write an algebraic expression to represents the verbal expression: the difference between the product of 4 and a number and the square of the number
Answer:
[tex]4n-n^2[/tex]
Step-by-step explanation:
I use 'n' as the unknown value, but you can use any letter you want as the variable.
The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.
The square of the number would be n². Squaring a number is multiplying a number by itself.
The phrase 'difference between...' means subtraction.
Putting it together:
"The difference between the product of 4 and a number and the square of the number" would be:
[tex]4n-n^2[/tex]

If on adding 9 to twice of a whole number gives 31, then the whole number is
Answer:
Hey there!
We can let x be that number.
2x+9=31
2x=22
x=11
The number is 11.
Let me know if this helps :)
Answer:
The whole number is 11.
Step-by-step explanation:
Let's call the whole number x. We can write the following equation:
2x + 9 = 31
Subtracting 9 from both sides of the equation gives us:
2x + 9 - 9 = 31 - 9
2x = 22
Dividing both sides of the equation by 2 gives us:
2x / 2 = 22 / 2
x = 11

) I went from my house to a playground, 300
metres away in 10 minutes. I ran back and
reached in 2 minutes. What was my average
speed? give answer fast!
Answer:
v = 0.834 m/s or 3 km/h
Step-by-step explanation:
Given that,
Distance between house and playground is 300 meters
If you went 300 metres away in 10 minutes and ran back and reached in 2 minutes, it means total distance covered by you during whole journey is 300 m + 300 m = 600 m
Total time, t = 10 min + 2 min = 12 min = 720 seconds
Total distance covered divided by total time gives average speed. So,
[tex]v=\dfrac{600\ m}{720\ s}\\\\v=0.834\ m/s[/tex]
or
v = 3 km/h
So, the average speed is 0.834 m/s or 3 km/h.

Answer:
(D) [tex]x>-10[/tex]
Step-by-step explanation:
If we have the inequality [tex]-7x + 4 > -8x - 6[/tex], we can simplify it down and get [tex]x[/tex] isolated on one side of the equation.
Add 6 to both sides:
[tex]-7x + 4 + 6 > -8x - 6 + 6\\\\-7x + 10 > -8x[/tex]
Add [tex]8x[/tex] to both sides of the inequality:
[tex]-7x + 10 + 8x > -8x+8x\\\\x + 10 > 0[/tex]
Subtract 10 from both sides of the inequality:
[tex]x + 10 - 10 > 0 - 10\\\\x > -10[/tex]
So (D) [tex]x>-10[/tex] is the correct simplification.

a) Work out the angle x
x=
b)Write down the value of angle y,giving your reason
Answer:
(A) 70°
(B) 67°, because they are alternate interior angles
Step-by-step explanation:
For a:
The angles of a triangle will all add up to 180°. Using the "feathers" (lines that signify congruence), we can tell that the angle connecting the two congruent lines will be different than the other two, which will be equivalent to each other.
This means that the angle measure of x will be [tex]180-55-55[/tex], or just [tex]180-110[/tex].
This is equal to 70°.
For b:
We know that the 67° angle and y are formed by the same line intersecting two parallel lines. This means that the angle measures of each intersection point will be the same as the other intersection point, however they will be flipped. This makes the concept of alternate interior angles. We know that the 67° angle and y are formed by the same line, this means that their angle lengths are the same - therefore y is 67°.

Pick out three equivalent fractions from the group 1/2 , 1/3, 3/4,3/6,2/4,4/10
Answer:
1/2, 3/6 and 2/4 are equivalent fractions.
Step-by-step explanation:
To know if the fractions are equivalent, their simplest form should be the same.
So we must simplify all the fractions to their simplest form.
To find the simplest form of a fraction, we must divide the numerator and denominator with their GCF (Greatest Common Factor)
So:
1/2 = 1/2
1/3 = 1/3
3/4 = 3/4
3/6 = 1/2 ( The GCF for 3 and 6 is 3)
2/4 = 1/2 ( The GCF for 2 and 4 is 2)
4/10 = 2/5 ( The GCF for 4 and 10 is 2)
Because 1/2, 3/6 and 2/4 has the same simplest form, they are equivalent fractions.
