Mo played 30 games of chess. He won 18 of these games. (b) He played 20 more games. He had then won 64% of all of his games. How many of the 20 games did he win?
Answer:
14
Step-by-step explanation:
First of all he played a total of 50 games which he won 32 of due to 64% of 50 being 32 then you subtract the 18 games he won at the start to get 32-18=14
would be amazing if you marked this as brainliest
Answer:
Total no of games played =50
percentage of the win game=64%
total no of won games =64/100×50
=32
no of games he won of the 20 =32-18
=14
so he won 14 games from 20

Find the missing angle.
Answer:
x = 81
Step-by-step explanation:
180 (62 + 37) = x
81 = x
Hope this helps!
Answer:
81
Step-by-step explanation:
x + 37 + 62 = 180
x + 99 = 180
x = 180 - 99
x = 81

determine whether 3y - 7 = 2x -7 represents direct variation or not. If it does, find the
constant of variation.
Answer:
Yes, it represents direct variation.
The constant of variation is 2/3.
Step-by-step explanation:
Rearrange the equation to put it into y = kx form, which is the direct variation equation
3y - 7 = 2x - 7
Add 7 to both sides:
3y - 7 = 2x - 7
3y = 2x
Divide each side by 3:
y = 2/3x
So, the equation is y = 2/3x, which represents direct variation because it is in the form y = kx.
In y = kx, k is the constant of variation. Since the equation is y = 2/3x, k = 2/3.
So, the constant of variation is 2/3.

The auditorium seated 375, but this was enough for only 30% of those who wanted a seat. How many wanted a seat but couldn't get one?
Answer: 875 people
Step-by-step explanation:
The 375 people seated represent 30% of the total number of people who wanted seats but these ones got them.
This means that the number of people who wanted seats is 70% of the number of people who wanted seats.
Assume the number of people who wanted seats is x:
30% * x = 375
x = 375 / 30%
x = 1,250 people wanted seats.
Those who wanted seats but couldn't get:
= 1,250 * 70%
= 875 people

Graph the system of inequalities.
Y > x+3
y > -2x+1
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The boundary lines of both inequalities are dashed lines, because neither includes the "or equal to" case. Shading is above the boundary line in both cases.
The boundary line of the first inequality has a y-intercept of +3 and a slope of 1, so goes up 1 unit for each 1 unit to the right of (0, 3).
The boundary line of the second inequality has a y-intercept of +1 and a slope of -2, so goes down 2 units for each 1 unit to the right of (0, 1).
The solution space is the top quadrant of the X where the boundary lines cross. That is where the two solution spaces overlap. It includes parts of quadrants I and II.
Find the measure of the indicated angle. Need help please.

THANK YOU
Answer: Approximately 28 km
The more accurate, yet still approximate value, is roughly 27.995735464379
Round that however you need to.
=============================================================
Explanation:
As the diagram shows, the uppercase letters A,B,C represent the corner points of the triangle. They also represent the angles. The diagram says that:
angle A = 59angle B = 91The missing angle C is....
A+B+C = 180
C = 180-A-B
C = 180-59-91
C = 30
which we'll use later.
Convention usually has the side lengths be lowercase letters 'a', b, and c. Those lowercase letters are opposite their uppercase counterpart. We'll have side 'a' opposite angle A, then b is opposite B, and c is opposite C. This allows us to quickly label a triangle and find the missing sides and/or angles. The phrasing "solve the triangle" basically means "find all the missing sides and angles". For this problem, we're only concerned with one side.
The diagram says that side c = 14 due to it being opposite angle C.
The goal is to find side b, which is the shorter way of saying "find AC".
-------------------------
From here, we can use the law of sines to find side b
b/sin(B) = c/sin(C)
b/sin(91) = 14/sin(30)
b = sin(91)*14/sin(30)
b = 27.995735464379 which is approximate
b = 28
Side AC is roughly 28 km long.
I rounded to the nearest whole number since the "14 km" is also a whole number. Your teacher may want you to round differently.

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
Given:
The quadratic equation is:
[tex]10m^2-7m+3=0[/tex]
To find:
The solutions for the given equation by using the quadratic formula.
Solution:
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have,
[tex]10m^2-7m+3=0[/tex]
Here, [tex]a=10,b=-7,c=3[/tex]. Using the quadratic formula, we get
[tex]m=\dfrac{-(-7)\pm \sqrt{(-7)^2-4(10)(3)}}{2(10)}[/tex]
[tex]m=\dfrac{7\pm \sqrt{49-120}}{20}[/tex]
[tex]m=\dfrac{7\pm \sqrt{-71}}{20}[/tex]
[tex]m=\dfrac{7\pm i\sqrt{71}}{20}[/tex] [tex][\because \sqrt{-a}=i\sqrt{a},a>0][/tex]
Therefore, the solution set of the given equation is [tex]\left\{\dfrac{7- i\sqrt{71}}{20},\dfrac{7+ i\sqrt{71}}{20}\right\}[/tex]. Hence, the correct option is D.
A system of linear equations has no solutions. One of the equations of the system is shown y=2x-1 which equation could be the other equation of the system
Answer:
D y = 2x + 2
Step-by-step explanation:
Set the equations equal
2x -1 = 2x + 2
Subtract 2x from both sides
-1 = 2 ... not possible
therefor no solution
there is no solution.

PLEASE HELP I’LL GIVE BRAINLIST!!!!!!!!
An object in free fall is dropping using only the force of gravity. Let's assume that is the case with the Drop of Doom for a moment just for the sake of our calculations.
When using feet to measure the distance traveled over time, we can approximate the force of gravity as -16ft/sec^2. That means every second, the speed of the ride is increasing at a rate of 16 ft/sec down towards the ground (hence the negative sign).
Zumanjaro is said to be a 415-foot drop. We can represent this fall using the function: h(t)= -16t^2+415, where h is the height above the ground (or in this case the height above the stopping point of the ride) in feet and t is the time in seconds.
Using this function, how long does the ride take to complete its 415 drop?

Solve this system of equations. Explain how you determined your answer.
2x−4y=−14
−8x+4y=−4
Answer:
(3, 5 )
Step-by-step explanation:
Given the 2 equations
2x - 4y = - 14 → (1)
- 8x + 4y = - 4 → (2)
Adding (1) and (2) term by term will eliminate the y- term
- 6x + 0 = - 18
- 6x = - 18 ( divide both sides by - 6 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (2)
- 8(3) + 4y = - 4
- 24 + 4y = - 4 ( add 24 to both sides )
4y = 20 ( divide both sides by 4 )
y = 5
solution is (3, 5 )
A new surgery is successful 70% of the time , if the results of 8 such surgeries are randomly sampled, what is the probability that more than 5 of them are successful?
Answer:
P (x>5) = 0.5324014=0.523
Step-by-step explanation:
Here success = p= 0.7 and failure = q= 1-p= 1-0.7 = 0.3
Number of surgeries= n= 8
Applying the binomial distribution
( p+q) ^n= nC x p^x . q^n-x
More than 5 means 6,7, and 8
( p+q) ^8= 8C 5 (0.7)^5 . (0.3)^3
=56* 0.16807*0.027
= 0.254121
( p+q) ^8= 8C 6 (0.7)^6 . (0.3)^2
= 28* 0.1177* 0.09
= 0.296604
( p+q) ^8= 8C 7 (0.7)^7 . (0.3)^1
= 8* 0.0824* 0.3
= 0.19776
( p+q) ^8= 8C8 (0.7)^8 . (0.3)^0
= 1* 0.05765* 1
=0.05765
Adding the above all probabilities gives
P (x>5) = P (x=6) + P(x=7) + P(x=8)
= 0.296604+0.19776+0.05765
= 0.5324014
