Class 10R sat a test
The mean mark for the class was 70%.
There are 30 students in class 10R, 20 of whom are boys.
The mean mark for the boys is 62%.
Work out the percentage for the girls
Answer:
86%
Step-by-step explanation:
You want the girls' average if the 20 boys in the 30-student class had an average of 62%, and the class average was 70%.
Weighted averageThe class average is the weighted average of the boys' score and the girls' score. The weights are the fraction of students of each gender.
class average = (1/3)(girls' average) +(2/3)(boys' average)
Girls' averageSolving this equation for the girls' average, we get ...
(1/3)(girls' average) = (class average) -(2/3)(boys' average)
girls' average = 3(class average) -2(boys' average)
girls' average = 3(70%) -2(62%) = 210% -124%
girls' average = 86%
__
Alternate solution
The sum of differences from the class average must be zero. The boys' average is 8 points below the class average, and there are 2 times as many boys as girls. Thus, compared to the girls, the boys contribute a total of 2·8 = 16 points below the class average. The girls must counter by having an average 16 points above the class average: 70+16 = 86.

ZA and B are supplementary angles. If mA (x - 9)° and
m/B= (7x + 21)°, then find the measure of ZB.
The measurement of ∠B is 168°
Given,
In the question:
Angle A and Angle B are supplementary angles.
If mA (x - 9)° and m/B= (7x + 21)°
To find the measure of ∠B
Now, According to the question;
What are supplementary angles?
Two angles are Supplementary when they add up to 180 degrees.
Now, ∠A+∠B = 180°
So,
⇒(x - 9)˚+(7x + 21)°=180°
=> 8x +12 = 180°
=> 8x = 180° - 12
=> 8x = 168
=> x = 168/8
=> x = 21
For the measure of ∠B :
∠B = (7x + 21)
∠B = 7 x 21 + 21
∠B = 168°
Hence, The measurement of ∠B is 168°

Which inequality represents the the maximum number of concert tickets Tayah can buy for the reduced price of $15.00?
Answer: 25 + 15x
x = 6 tickets.
Step-by-step explanation:
First of all, we need to write an equation.
The equation will be x = $25 + $15x.
Now, we need to use trial and error. I'm going to try plugging in 9 into X because I know that 10 would be too big.
25 + 15(9)
25 + 135

How long would it take the auxiliary equipment to fill the order working alone
It take the auxiliary equipment to fill the order working alone x is 70/3
How long would it take?Formulate based on the conditions stated:
10 * x/(10+x) = 7
In a defined fraction, the denominator cannot be zero.
10+x is not equal 0
Equation from inequality:
10+x=0
Unknown terms should be moved to the left side of the equation:
x = -10
Equation to inequality conversion
x is not equal to 10
As the domain, append the inequality:x is not equal to 10
Divide the common denominator by both sides of the equation:
10x(10+x)/10+x = 7(10+x)
Cut the fractions in half:
10x = 7(10+x)
Use the law of multiplicative distribution
10x = 70 +7x
Unknown terms should be moved to the left side of the equation:
10x-7x=70
combining similar terms 3x =70
Subtract the coefficient of the variable from both sides of the equation:
x = 70/3
the intersection, then: 70/3
get the outcome:x = 70/3
It take the auxiliary equipment to fill the order working alone x is 70/3

What are congruent triangles?The size of the sides and angles determines whether two or more triangles are congruent. The three sides and three angles of a triangle define its size and shape, accordingly. Two triangles are said to be congruent if their respective side and angle pairs are the same. They are identical in terms of both dimensions shape and size.
Given AB = AC
∠1 = ∠2
Consider, triangke BDC
If two angles are equal then their opposite sides are equal. Therefore,
BD = DC
Now consider triangles ADB and ADC
AB = AC (given)

Now, for the first one, we have to find number of children to be supervised by 8 adults.
1 adult = 6 children
8 adults = 8*6 children
8 adults = 48 children
Now, for the second one, we have to find the number of adults for 66 children:
1 children = 1/6 adult
66 children = 66/6 adults
66 children = 11 adults
Now, for the third one, we have to find number of children for 15 adults:

Options:
1. The height of the ball would be zero at 20 seconds.
2. The ball will be on the ground and 20 seconds.
3. The ball would bounce and go back to a height of 50 feet.
4. g(x) = 0.
5. there is not enough information to answer this question.
Tell me all the options like this: Option 1,2,4.
Step-by-step explanation:
the correct answer IS options 1, 2, 4.
the curve shows us that the ball hits the ground (height 0) at 12 seconds and then stays there.
so, at 20 seconds the height is 0, as the ball is on the ground, and so the functional result g(x) = 0.
actually that is g(20) = 0.
as g(x) gives us the height of the ball x seconds after throwing it out of the window.
although I have to say : the graph does not show us the situation at 20 seconds (it ends at 16 seconds). maybe somebody picks it up (so, it would move up again). we don't know.
so, there is some point for option 5.
but normally, we can say 1, 2, 4 are correct.
option 3 is definitely out, because the ball would not suddenly, after 8 seconds (from 12 to 20 seconds) flat on the ground, start bouncing again.
