The best player on a basketball team makes 95% of all free throws. The second-best player makes 90% of all free throws. The third-best player makes 80% of all free throws. Based on their experimental probabilities, estimate the number of free throws each player will make in his or her next 40 attempts. Explain.
Answer: See explanation
Step-by-step explanation:
The best player on a basketball team makes 95% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 95% × 40
= 95/100 × 40
= 0.95 × 40
= 38
The second-best player makes 90% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 90% × 40
= 90/100 × 40
= 0.90 × 40
= 36
The third-best player makes 80% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 80% × 40
= 80/100 × 40
= 0.80 × 40
= 32

Triangle ABC is a right triangle. Triangle A B C is a right triangle. Angle A C B is 90 degrees, angle C B A is 31 degrees, and angle B A C is 59 degrees. What is the relationship between angles A and B?
Answer:
see explanation
Step-by-step explanation:
Complementary angles sum to 90°
∠ CBA = 31° and ∠ BAC = 59° , sum to 90° (31° + 59° = 90° )
Thus
∠ A and ∠ B are complementary angles
Answer: They are complementary

The diagram compares the ratio of girls in the chorus to boys in the chorus. What is the ratio of girls to boys? If there are 50 students in the chorus, how many are girls, and how many are boys? ??50 The ratio of girls to boys is too. The number of girls in the chorus is. The number of boys in the chorus is.
Answer:
there are a total of 20 boys and 30 girls in the choir of 50 students
Step-by-step explanation:
Scale the ratio 2:3. so that the numbers on either side sum to 50 . 2+3=5 , and 50÷5=10 , so we scale our ratio by a factor of 10 . So there are a total of 20 boys and 30 girls in the choir of 50 students

Answer:
y=(-4/3)x+2
Step-by-step explanation:
we have two points (3,-2) and (0,2) given from the statement
the equation of the lines is:
y=mx+b
m=slope
m=(y2-y1)/(x2-x1)
m=(2-(-2))/(0-3)
so we have the slope is
m=4/-3 =-4/3 =-1.3333
we need to find "b"
using the point (0,2)
we have :
2=m*0+b
2=b
finally, we have
the answer is y=(-4/3)x+2

Which equation represents the line that is perpendicular to y = $5 + 23 and passes through (-40,2012

y = - = - 30
= 5 + 52
= - 56
ОВ.
Ос. y =
OD.
Answer:
The question is written kinda bad, so i take the next two assumptions:
The original line is:
y = 5*x + 23
And we want to find a perpendicular line that passes through the point (-40, 2012)
Suppose that we have a linear equation:
y = a*x + b
A perpendicular line to this one, will have a slope equal to -(1/a)
Then a random perpendicular line to the one above, is:
y = -(1/a)*x + c
In this case, we start with the line:
y = 5*x + 23
Then the family of perpendicular lines to this one, will be like:
y = (-1/5)*x + c
Where c can be any real number.
Now, we also want this line to pass through (-40, 2012)
This means that when x = -40, the value of y must be 2012
We could replace these values in our equation above and solve it for c.
2012 = -(1/5)*(-40) + c
2012 = 40/5 + c
2012 = 8 + c
2012 - 8 = c = 2004
Then the equation is:
y = -(1/5)*x + 2004.
A deli owner sold 90 sandwiches in one day. Of those sandwiches, 36 were pastrami. Write an equation to show what percent of sandwiches sold were pastrami
Answer:
36/90 * 100 = p
(p is percent sold that were pastrami)
Step-by-step explanation:
First, 36/90 (part over whole), simplifies to 40/100. We can multiply that by 100 to get a percentage. And that is your equation.

Answer:
BD = 12.1 (nearest tenth)
Step-by-step explanation:
∆ABC is an isosceles triangle, since it has two equal sides, AB and BC. Also, this means that <BAD and <BCD = 60° each.
BD divides ∆ABC into two equal parts.
Apply trigonometric ratio to find BD.
Reference angle = <BAD = 60°
Adjacent = AD = 7
Opposite = BD
Thus, we would have:
tan 60 = opp/adj
Tan 60 = BD/7
7*Tan 60 = BD
12.1 = BD
BD = 12.1 (nearest tenth)
Gabby has 20 coins in her pocket that are quarters, dimes, and nickels. The total value of the coins is $2.70. The number of nickels that she has is equal to the number of quarters plus the number of dimes. Choose the system of equations that can be solved to find the number of quarters, 9, dimes, d, and nickels, n, that Gabby has.
Answer:
There's 9 nickels and no dimes
Step-by-step explanation:
the quarters equal $2.25
so there is at least 9 nickel's witch equals .45 cents add them and get $2.70 so
The system of equations to find the number of quarters, 9, dim, d, and nickels, n, that Gabby has are;
n = q + dn = 10q +d = 10Since, the total value of quarters, dim, and nicke is; $2.70.
Since the number of nickels that she has is equal to the number of quarters plus the number of dimes; we have;
n = q + dSince, Gabby has 20 coins in her pocket.
n + q + d = 20Therefore 2n = 20 from n = q + d
n = 10Read more on system of equations:

[tex]consider \: triangle \: BDE \\m<BCD = m<BED \\ angles \: of \: triangle \: sum \: up \: to \: 180 ° \\ (14x + 4)° + 55° + 51° = 180° \\ 14x = 180° - (4 + 55 + 51)° \\ 14x = 70° \\ x = \frac{70}{14} \\ x = 5[/tex]
Answer:
x = 5
Step-by-step explanation:
all angles at corners in parallelogram must add to 360
bcd = 51 thus angle at opposite corner (bed) must also equal 51
adding = 51 + 51 = 102
angles at ebc and edc are also equal to each other
edf = 55 and cbf = 55
adding 55+55 = 110
360 - 110 - 102 = 148
divide by 2 for angles ebf and cfd
148/2 = 74
now solve
14x + 4 = 74
14x = 70
x = 5

Tamara has $50 to spend on craft supplies. She spends $30
plus a 5% tax at the store. How much change should she
receive?
Answer:
the answer is $18.5
Step-by-step explanation:
30 + tax is $31.50
Answer:
$18.50
Step-by-step explanation:
Before Tax Price: $30
Sales Tax Rate: 5%
After Tax Price: $18.50
How can you find how much the sales tax is? Let's say you're buying a $100 item with a sales tax of 5%. Your math would be simply:
[cost of the item] x [percentage as a decimal] = [sales tax]
Step 1 : $30 x .05 (5%) = $1.50 Step 2 : $30 + $1.50 = $31.50Step 3 : $50 - $31.50 = $18.50How do i get the answer x= 3, -1 for equation (3/x^2)+ 2/x =1
Answer:
Steps below
Step-by-step explanation:
(3/x²)+ 2/x =1 (x ≠ 0)
(3/x²) + 2x/x² = 1
(3 + 2x) / x² = 1
3 + 2x = x²
x² - 2x - 3 = 0
(x + 1) (x - 3) =0
x = -1 or x = 3

Han earns $33.00 for babysitting 4 hours. At this rate, how much will he earn if he
babysits for 7 hours. You may solve with any method but you must show your work.
Step-by-step explanation:
First, you want to find the unit rate, or how much Han earns per hour
You can do this by setting up an equation
x= amount earned per hour
4x= 33 Initial equation
4x/4 = 33/4 Isolating the variable
x = 33/4 = 8 1/4 = 8.25 The unit rate
Now you want to set up a new equation to find out how much he makes for 7 hours
x= amount earned per hour
y = total amount earned
y = 7x Initial equation
y = 7 ( 8.25) Substitution
y = 57.75 The answer
Han earns $57.75 for every 7 hours
Checking the answer....
y = 7x
57.75 = 7x Substitute y instead
57.75/7 = 7x/7
8.25 = x
Your answer should be correct

Kayla thinks that the slope of a vertical line is undefined, while Joshua argues that the slope of a vertical line is zero. Who is correct? *
Answer:
Kayla is correct
Step-by-step explanation:
For a vertical line, the x-value is the same
This means there is no change in the x value
A slope is calculated by dividing by the change in x value
since in this case , we will be dividing by zero, it means that the value of our slope is going to be undefined
This means that Kayla is correct
