850 students so those with no participation would be 12% of 850, which is also 0.12*850. Only one sport would be 0.42*850. Two sports would be 0.28*850. Three or more sports would be 0.18*850.
No participation: 102 students
Only one sport: 357 students
Two Sports: 238 students
Three of more sports: 153 students
Answer:
No Participation: 102 students
Only One Sport: 357 students
Two Sports: 238 students
Three or More Sports: 153 students
Step-by-step explanation:
The percentages represent parts of the total.
To calculate the number of students, we would need to take a percentage of the total.
So for the No Participation group, we would take 12% of 850. "Of" indicates that we would multiply the terms together.
To multiply a %, we first need to convert it to a decimal by moving the decimal point to the left two times.
The No Participation group would then be 0.12 × 850 which equals 102.
The 1 sport group would be 0.42 × 850 = 357
The 2 sport group would be 0.28 × 850 = 238
And the 3+ sport group would be 0.18 × 850 = 153

plss someone help my do this problem (a^14 • a^-6 / a^25)^3
Answers
Answer:
[tex]a^{-51} = \frac1{a^{51}}[/tex]
Step-by-step explanation:
When you're multiplying two powers with the same base (in our case, a) you add together the exponents.
[tex](\frac{a^1^4\cdot a^-^6}{a^{25}})^3 =\\(\frac {a^{14+(-5)}}{a^2^5})^3= (\frac {a^{14-6}}{a^2^5})^3 = (\frac {a^{8}}{a^2^5})^3[/tex]
Now, when you are dividing two powers with the same base (in our case, a again) you subtract the exponents:
[tex]= (a^{8-25})^3 = (a^{-17})^3[/tex]
Finally, when you're calculating the power of a power, you multiply the exponents together:
[tex]a^{-17\cdot 3} = a^{-51} = \frac1{a^{51}}[/tex]
At this point you just have to choose - or check with your book/teacher if you prefer a negative exponent, or a fraction.
if P1 is (3,-3) and the midpoint is (-2,1), what are the points of P2?
Answers
Step-by-step explanation:
Hey there!
The points P1(3,-3) and midpoint is (-2,1). Let (X,y) be the end point.
Note: Find through using midpoint formula.
midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )
Put all values.
(\frac{X+3}{2},\frac{-3+y}{2})
Since they are equal, equating with it's corresponding components.
\frac{3 + x}{2} = - 2
-2 = 3 + x
-4 -3= x
Therefore, X= -7.
Now,
[tex] \frac{ - 3 + y}{2} = 1[/tex]
[tex] - 3 + y = 2[/tex]
Therefore, y= 5
Therefore, the other end point is (3,5).

Diego pays $4.50 for 3 pounds of bananas and 2 pounds of oranges. One pound of oranges cost $0.75 more than one pound of bananas let b represent the price per pound of bananas. Which equation represents the situation, and what is the price per pound of each fruit?
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Let banana = b
Oranges = a
3b + 2a = 4.50 - - - (1)
a = 0.75 + b - - - (2)
Substitute (2) into (1)
3b + 2(0.75 + b) = 4.50
3b + 1.5 + 2b = 4.50
5b = 4.50 - 1.50
5b = 3
b = 3/5
b = $0.6
a = 0.75 + 0.6
a = $1.35

Answer:

Step-by-step explanation:
Let the number of people be x.
Rs. 1000 is distributed equally among x people, so each person gets 1000/x.
If there were 5 people more, there would be x + 5 people.
Then, each person would get 1000/(x + 5). Each of the x + 5 people would get Rs. 10 less than before.
1000/x - 10 = 1000/(x + 5)
Multiply both sides by the LCD, x(x + 5).
x(x + 5) × 1000/x - x(x + 5) × 10 = x(x + 5) × 1000/(x + 5)
(x + 5) × 1000 - (x² + 5x) × 10 = x × 1000
1000x + 5000 - 10x² - 50x = 1000x
5000 - 10x² - 50x = 0
10x² + 50x - 5000 = 0
x² + 5x - 500 = 0
(x + 25)(x - 20) = 0
x + 25 = 0 or x - 20 = 0
x = -25 or x = 20
The actual number of people is 20.
Check:
Rs. 1000/20 = Rs. 50
Rs. 1000 divided equally among 20 people gives Rs. 50 per person.
If there are 5 people more, then there are 25 people.
Rs. 1000/25 = Rs. 40
Rs. 1000 divided by 25 people gives Rs. 40 per person which is Rs. 10 less per person.

A kite is inscribed within a square with a side lengths of 9 units. A kite is inscribed in a square with a side length of 9 units. What is the area of the kite? 27. 5 square units 36. 0 square units 40. 5 square units 45. 0 square units.
Answers
Answer:
40.5 Units
Step-by-step explanation:
The area of a kite is A = (d1d2) / 2, where d1 and d2 are the diagonals of the kite.
Since the kite is inscribed in the square, and the sides of the square are 9 units, the diagonals of the kite are both 9 units.
d1 = 9 units
d2 = 9 units
A = (9units * 9units) / 2
A = 81units² / 2
A = 40.5 units²

The sum of 5 consecutive even numbers is 200
Answers
Answer:
36, 38, 40, 42, 44
Step-by-step explanation:
We can denote an even number as 2n (where n is a natural number).
Each consecutive even number will be 2 more than the previous number.
Let 1st number = 2n
⇒ 2nd number = 2n + 2
⇒ 3rd number = 2n + 4
⇒ 4th number = 2n + 6
⇒ 5th number = 2n + 8
Sum of all 5 numbers is 200.
⇒ 2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 200
⇒ 10n + 20 = 200
⇒ 10n = 180
⇒ n = 18
If n = 18, then 2n = 36
Therefore, the numbers are 36, 38, 40, 42, 44

D) v = x + 1
Answers
Answer:
Option (D)
Step-by-step explanation:
Let the equation of the line be,
y = mx + b
where m = slope of the line
b = y-intercept
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Since, line 'l' is passing through two points (0, 1) and (-1, 0),
Therefore, slope 'm' = [tex]\frac{1-0}{0+1}[/tex] = 1
y-intercept 'b' = 1
Therefore, equation of the line will be,
y = 1(x) + 1
y = x + 1
Option (D). will be the answer.

A window seat is in the shape of a trapezoid. Write the polynomial that represents the area of the window seat.
Answers
The polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).
What is the Area of a Trapezoid?Area of trapezoid = 1/2(a + b)h, where a and b are length of the parallel sides, and h is the height.
Given:
a = 3x + 5
b = x - 2
h = 2x - 5
Thus:
Area of trapezoid = 1/2(3x + 5 + x - 2)(2x - 5)
Area of trapezoid = 1/2(4x + 3)(2x - 5)
Area of trapezoid = 1/2(8x² - 14x - 15)
Therefore, the polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).

Carrie wants to make half of the recipe to make 12 pancakes. In simplest form, how many cups of dry pancake mix will she need in order to make 12 pancakes?
A
16/3
B
5 2/3
C
5 1/3
D
21 1/3
Answers
=======================================================
Explanation:
The box says 10 & 2/3 cups of mix will make 24 pancakes.
Carrie only wants to make half that and only wants 12 pancakes.
So we'll divide the mixed number in half.
This means we divide each piece of the mixed number in half like so
10 divided by 2 = 52/3 divided by 2 = 1/3, which you can think of it like 2/2 = 1 then place that over 3.Overall, the mixed number 10 & 2/3 divides in half to get 5 & 1/3 which is the final answer.
------------
To check the result, notice that
2*5 = 102*(1/3) = 2/3Meaning that doubling 5 & 1/3 lands us on 10 & 2/3.
The answer has been confirmed.
