Answer:
428
Step-by-step explanation:
Its says out of 60, 29 of them play sports
so we want to use proportions to solve for how many would play if there were 887 kids
[tex]\frac{60}{29} =2.068965517\\\frac{887}{2.068965517} = 428[/tex]
thus meaning that out of 887 kids 428 of them would play sports
ben positions his ladder against a wall so that the top of the ladder is 15 feet above the ground. about how long is his ladder?
A. 16.2 feet
B. 18.6 feet
C. 10.5 feet
D. 21 feet
Answer: 16.2 ft
Step-by-step explanation:
Using the Pythagorean theorem, if we let the length of the ladder be x,
[tex]6^{2}+15^{2}=x^{2}\\\\261=x^{2}\\\\x=\sqrt{261} \approx \boxed{16.2 \text{ ft}}[/tex]

Answer:
(b) ... confirm ∠C≅∠E
Step-by-step explanation:
The first step is to read and understand the problem statement. It is asking for a way to prove ΔABC ~ ΔADE by AA similarity. That means you want to show any two of the three ...
∠A≅∠A∠B≅∠D∠C≅∠EFor this purpose, lengths of line segments are irrelevant (eliminating the last two answer choices). The fact that ∠A≅∠A is given, so you only need to find an answer choice that will show one of the last two angle congruences.
Obviously, showing ∠B≅∠E (choice A) is not relevant to the problem.
The only answer choice that is relevant to the question is the second one, showing ∠C≅∠E.
The scientist measured the wingspans of another random sample of hawks in the national park. There were 100 hawks in the sample, and the number of hawks in the park is about 2,750. There were 82 hawks in the random sample that had a wingspan less than 50 inches. Which value best estimates the number of hawks in the national park that have a wingspan less than 50 inches?

Answer:A
Step-by-step explanation:
The average of 15 test scores is 80. If the average of first eight test scores is 65 and that of the last eight test scores is 70, then the eighth score is 80.
True or False?
Answer:
FalseStep-by-step explanation:
The average of 15 test scores is 80.
The total is:
15*80 = 1200The average of first eight test scores is 65.
The total is:
8*65 = 520The average of last eight test scores is 70.
The total minus 8th score is:
8*70 - 80 = 480The sum gives us the total of 15 scores:
520 + 480 = 1000 < 1200The answer is FALSE
There are 8 pieces of fruit in a bowl and 6 of them are apples. What percentage of the pieces of fruit in the bowl are apples?
_______% are apples.
Answer:
80%
Step-by-step explanation:
Because the answer is 80%
Answer:40 percent
Step-by-step explanation:Total number of fruit in a bowl is 15 pieces.
Number of apples are 6 pieces in a bowl.
6/15 times 100 equals 40%
Find the average of the following numbers. -100 and 102.
The average is the sum of the numbers divided by the quantity of numbers.
-100 + 102 =2
2/2 = 1
The average is 1
Answer:
1
Step-by-step explanation:
To find average, add up all of the numbers and divide it by how many numbers there are.
[tex]\frac{-100+102}{2} = \frac{2}{2} =1[/tex]

B. 3(2x+1)(x-2)
C. 3(2x+2)(x-1)
D. 3(2x+2)(x-6)
all my points are yours for your answer
Answer:
B. 3(2x+1)(x-2)
Step-by-step explanation:
For this case we have the following trinomial:-
6x^2-9x-6
Rewriting we have:-
3(2x^2-3x-2)
Factoring we have:-
3(2x+1)(x-2)

Answer:
22/29
Step-by-step explanation:
Add up all the eight grade student that participated in this survey which is 29.
Then add all the eight grade students that do not play guitar which is 22. So 22/29 is the amount of students that play an instrument other than a guitar in fraction form.
Hopefully you got the correct answer. Let me know if you got it wrong.
Sean took 6 tests and currently has an average of a 90. His range of his scores was 18 and the mode of the test scores is 89.
Answer:
what is the question?
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
Total scores = 6*90 = 540.
He had more than one 89 ( mode) and max score - min score = 18.
Let max score = x then min = x-18.
Lets say he has 3 89's then
x + x - 18 + 3*89 + y = 540 where y is another score then:
2x + 249 + y = 540
2x + y = 291
x = 98 and y = 95 will fit this so the 6 scores could be
80, 89, 89, 89, 95, 98.

List the key features of the quadratic function y = –x2 + 4x – 3.
The key features of the quadratic function are
vertex is (2, 1)Axis of symmetry: x = 2The domain of the function is the set of all real valuesDetermining the key features of the quadratic functionFrom the question, we have the following parameters that can be used in our computation:
y = -x² + 4x - 3
A quadratic function is represented as
y = ax² + bx + c
By comapring the equations, we have
a = -1, b = 4 and c = -3
For the key features
Axis of symmetry: x = -b/2a
So, we have
x = -4/(2 * -1)
x = 2
The domain of the function is the set of all real values
For the vertex, we have
(h, k) = (symmetry, f(symmetry))
So, we have
y = -2² + 4(2) - 3
y = 1
So, the vertex is (2, 1)

What’s the answer and how to get it done without me
Answer:uhmmmmm
Step-by-step explanation:
The university has decided that for the following year lecture costs will increase by 20% workshop costs by 10% and examination costs will stay the same .For level 2 the current hourly costs are 10,24,and 60 respectively. how much would the level 2 course cost in the following year
Answer:
$98.4.
Step-by-step explanation:
Since the university has decided that for the following year lecture costs will increase by 20%, workshop costs by 10%, and examination costs will stay the same, and that for level 2 the current hourly costs are 10, 24, and 60 respectively To determine how much the level 2 course cost in the following year, the following calculation must be performed:
10 x 1.2 + 24 x 1.1 + 60 = X
12 + 26.4 + 60 = X
98.4 = X
Thus, the level 2 course will cost $ 98.4 next year.
Alex needs 36 boxes in the carton above.
Answer:
1 stack of 36
Step-by-step explanation:
First find how much one carton can hold
length is 45
width is 20
height is 40
40 * 20 * 45 = 36,000
Then find how much volume each box has
length is 20
width is 10
height is 5
5 * 10 * 20 = 1000
so each box is 1000 volume
1 stack of 36 is good

TRIGONOMETRY
Answer:
9). x = 36.9°
10). x = 18.3°
Step-by-step explanation:
9). By applying tangent rule in the given triangle,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{9}{12}[/tex]
x = [tex]\text{tan}^{-1}(\frac{3}{4})[/tex]
x = 36.87°
x = 36.9°
10). By applying sine rule in the given triangle,
sin(x) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(x) = [tex]\frac{11}{35}[/tex]
x = [tex]\text{sin}^{-1}(\frac{11}{35})[/tex]
x = 18.32
x ≈ 18.3°

Answer:
y=2 and x=1
Step-by-step explanation:
sub 2 into 1
3(15-7y) + 4y= 11
45 - 21y +4y =11
-21y+4y= 11-45
-17y= - 34
y=2
Therefore sub y into x equation
x=15-7(2)
x= 1
Answer:
3x + 4y = 11
x = 15 -7 y
3 (15-7y) = 11
45 - 21y + 4y = 11
45 - 17 y = 11
-17 y =11 -45
-17y ÷ -17 = -34 ÷ -17
y = 2
x = 15 - 7y
x = 15 - 7(2)
x = 15 - 14
x = 1
there for y = 2 and x = 1 is the solution
