In the first half of the basketball season, Jean made 15 free throws out of the 25 free throws she attempted, for a free-throw shooting percentage of 60%. How many consecutive free-throw shots would Jean have to make to raise her free-throw shooting percentage to 80%?
Answer:
She has to make 25 consecutive free throws
Step-by-step explanation:
Let the number of consecutive throws be x
So, that would mean the number of free throws would total 25 + x
while the number of free throws made would be 15 + x
So for us to have an 80% raise ;
That would mean;
(15 + x)/(25 + x) * 100 = 80
100(15 + x) = 80(25 + x)
1500 + 100x = 2000 + 80x
2000-1500 = 100x-80x
20x = 500
x = 500/20
x = 25
Answer:
She has to make 25 consecutive free throws
Step-by-step explanation:
Let the number of consecutive throws be x
So, that would mean the number of free throws would total 25 + x
while the number of free throws made would be 15 + x
So for us to have an 80% raise ;
That would mean;
(15 + x)/(25 + x) * 100 = 80
100(15 + x) = 80(25 + x)
1500 + 100x = 2000 + 80x
2000-1500 = 100x-80x
20x = 500
x = 500/20
x = 25

For x = [tex]-9\frac{1}{2}[/tex]
Value of the expression will be,

What is the median. I have 3 more questions that have to deal with the median.
Answer:
47.5Step-by-step explanation:
Median - The middle number in a list of numbers starting from least to greatest.
Knowing this, we can start.
The first step is to rewrite all the numbers from least to greatest
15, 19, 28, 32, 43, 52, 66, 72, 72, 81
Now cross off a number from the least and greatest until there is 1 or 2 numbers left
19, 28, 32, 43, 52, 66, 72, 72
28, 32, 43, 52, 66, 72
32, 43, 52, 66
43, 52
If you are left we 1 number, that is your answer. If you are left with 2 numbers, there is an extra step
In the case that you have 2 numbers, you need to add them together, and divide by 2
43 + 52 = 95
95 ÷ 2 = 47.5
Thus 47.5 is our answer
Plz help! Sam had an appointment 90 miles away from home at 2pm. He drove there at 60 mph, and was 15 minutes late. What time did Sam start driving at?
Example: 1:50
Answer:
12:45 pm
Step-by-step explanation:
First we find out the amount of time it takes to drive 90 miles at 60 mph.
speed = distance/time
time * speed = distance
time = distance/speed
time = 90 miles / 60 mph
time = 1.5 hour = 90 minutes
It takes 1.5 hour, or 90 minutes, to drive 90 miles at a speed of 60 mph.
To get there at 2:00 pm, he should have left at 12:30 pm.
He got there 15 minutes late, so he must have left 15 minutes late.
He left at 12:45 pm.
Answer: 12:45 pm

Some people use SOH - CAH - TOA to remember the trigonometric ratios for sine, cosine, and tangent. Why do you think that word might help?
Answer:
hope this is helpful
Step-by-step explanation:
SOH-CAH-TOA is really helpful in remembering what each of the ratios should look like.
For sine, SOH means --> Sine- Opposite- Hypotenuse
This helps to remember that when using sine, you should use the Opposite length over the Hypotenuse in your ratio.
For cosine, CAH means --> Cosine- Adjacent- Hypotenuse
Your ratio should have the Adjacent length over the Hypotenuse
For tan, TOA means --> Tangent- Opposite- Adjacent
Your ratio should have the Opposite length over the Adjacent length

In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.
Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth.
Note: The unit for Force (the Newton) is measured in .
Answer:
2.2
Step-by-step explanation:
if force equals mass times acceleration then you divide 7.92(the force) by 3.6(the mass) to find out what would be multiplied by 3.6 to get 7.92.
Sorry if I'm wrong.
The acceleration of an object with F=7.92 newtons and m=3.6 kilograms is 2.2 m / s²
What is force:Force is a pull or push upon an object that causes motion .
Mathematically, force is express as follows:
F = ma
where
m = mass
a = acceleration
Force is measured in Newton.
Let's find the acceleration of an object with F =7.92 newtons and m = 3.6 kilograms.
7.92 = 3.6a
divide both sides by 3.6
a = 7.92 / 3.6
a = 2.2 m / s²

Answer:
x = 15Step-by-step explanation:
Since the quadrilateral is inscribed into circle, its opposite angles are supplementary:
m∠H + m∠K = 180°Substitute the values and solve for x:
5x - 22 + 8x + 7 = 18013x - 15 = 18013x = 195x = 195/13x = 15Answer:
Solution ::According to the property of Cyclic Quadrilateral
5x - 22 + 8x + 7 = 180
(5x + 8x) - (22 - 7) = 180
13x - 15 = 180
13x = 180 + 15
13x = 195
x = 195/13
x = 15

I hope it's helps you
Answer:
x=154
Step-by-step explanation:
The figures provides us with a variable and the number 154.
In this situation, the value of x and the given angle are corresponding angles.
The theorem of corresponding angles states that if a transversal is cut by two parallel lines the corresponding angles are CONGRUENT.
When an angle is congruent, they are equal to each other.
So in this case, x=154, x≅154.
