Answer:
"When you will get the factors of 80 you will get 2 * 2 * 2 * 2 * 5.
These numbers are the prime numbers that make them the prime factor of the 80.
It is known as prime because the number will not be divided by any other number except themselves or 1."

1. Identify and explain one way in which the movie portrays historical facts accurately in the movie (History vs. Hollywood).
Hal is downloading a file from the internet. So far he has downloaded 25% of the file.
If 10 minutes have passed since he started, how long will it take to download the rest of the file?
Answer:
30 minutes
Step-by-step explanation:
If it takes 10 minutes to download 25%, and there is 75% left to reach 100%.
25% + 25% +25% = 75% there are 3 25% left thus,
10min + 10min + 10min = 30 minutes left to complete download.
The amount of time in minutes it will take to download the rest of the file
is 30 minutes.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Let, 'x' be the number of minutes required to download the complete movie.
Therefore,
25% of 'x' is 10 minutes, This can be numerically expressed as,
(25/100)×x = 10.
0.25x = 10.
x = 10/0.25.
x = 40 minutes.
So, it would take 40 10 = 30 minutes.

6. What is the solution of the system
of equations?
2x + 3y = 12
-6y = 4x - 24
A. X = 3, y = 2
B. X = 6, y = 0
C. Infinitely many solutions
D. No solution
Answer:
C
Step-by-step explanation:
If you rewrite the questions into linear form (y=mx+b) then you get
For the first one
2x-12= -3y
Divide by -3 and get
-2/3x +4 =y
For the second one
-6y=4x -24
Divide by -6 and get
y= -4/6x +4
Simplify the fraction and you get -2/3x+4 =y
Obviously these two lines are identical meaning that any number will work

independent practice: tangents of circles
Find the value of x in each of the following:
(see picture)
Answer:
Step-by-step explanation:
9). "Tangent is perpendicular to the radius of a circle"
By applying Pythagoras theorem in the given triangle,
x² = 15² + 20²
x = √625 = 25
10). By applying Pythagoras theorem in the given triangle,
(r + x)² = r² + 15²
(8 + x)² = 8² + 225
8² + x² + 16x = 8² + 225
x² + 16x = 225
x² + 16x - 225 = 0
x² + 25x - 9x - 225 = 0
x(x + 25) - 9(x + 25) = 0
(x + 25)(x - 9) = 0
x = -25, 9
But x > 0
Therefore, x = 9 is the answer.
11). By the property of the tangents drawn to the circle from a point,
"Tangents drawn from a point lying outside the circle are equal in measure"
AC = BC
3x + 4 = 40
3x = 36
x = 12
12). By the same property used in question (11)
DE = DC = 4 units
BA = BC = 3 units

can anyone help me create the equation of the given parabola . is it x^2-x-3?
Answer:
The function of this parabola is is equal to [tex]f(x) = (x-1)^{2} - 4[/tex]
Step-by-step explanation:
If we look at this picture we cans see that the most bottom point of this parabola is located 4 units below and 1 unit tot he right of the origin point. From here we know tha tthe function will lokk something like this....
[tex]f(x) = (x^-1)^{2} + bx - 4[/tex]
But in our case b is equal to zero and so we get that the following parabola is represented by the following function....
[tex]f(x) = (x-1)^{2} - 4\\[/tex]
(If you don't believe me you can check this function on a graphing site called Desmos)

Step-by-step explanation:
a ball is launched upward from the ground with an initial velocity of 20 ft/s. The height of the ball at time t is represented by the function h(t). h(t)=-16t^2+20t, where t is measured in seconds and h(t) is measured in feet. drag the values to the lines to complete each sentence.
1. The ball reaches its maximum height when t is ____ seconds.
2. The maximum height of the ball is ____ feet.

OPTIONS: 0.4 0.625 0.8 1.25 5.44 6.25 12.5 25
Answer:
1.-t₁ = 0,625 s
2.-h(max) = 6,25 f
3.-t = 1,25 s
Step-by-step explanation:
V₀ = 20 f/s
h(t) = - 16*t² + 20*t
h(max) = ??
h´(t) = - 32*t + 20
h(max) will occurs when V = 0 dh/dt = 0 then
- 32*t + 20 = 0
- 32*t = -20
t = 20/32
t₁ = 0,625 s
h(max) = h(0,625) = - 16*(0,625)² + 20*0,625
h(max) = - 6,25 + 12,5
h(max) = 6,25 f
c) The ball will hit the ground
t = 2*t₁
t = 2*0,625
t = 1,25 s

Lily, Juliet, and Willow are baking muffins. Lily has 1 1/2 cups of flour, Juliet has 3/4 cup of flour, and Willow has 1 2/6 cups of flour. How many cups of flour do they have altogether?
Answer: 3 7/12
Step-by-step explanation:
From the question, we are given the information that Lily has 1 1/2 cups of flour, Juliet has 3/4 cup of flour, and Willow has 1 2/6 cups of flour.
The number of cups of flour that they have altogether would be the addition of all the fractions of each girl. This would be:
= 1 1/2 + 3/4 + 1 2/6
The lowest common multiple is 12, therefore we make them have a common denominator
= 1 6/12 + 9/12 + 1 4/12
= 2 19/12
= 2 + 1 7/12
= 3 7/12 cups

Answer:
The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}
Step-by-step explanation:
The domain is the set of values of the input (x)
The range is the set of values of the output (y)
In the given figure
∵ x is the input
∴ The set of the values of x is the domain
∵ Y is the output
∴ The set of the values of y is the range
∵ The smallest value of y is -6
∵ The greatest value of y is 8
→ That means values of y of the graph are from -6 to 8
∴ -6 ≤ y ≤ 8
∴ The range = {y : y ∈ R, -6 ≤ y ≤ 8}
∴ The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}

Sneakers at Mr. Lou's garage sale cost the same price. Alexander paid $90.52 for four pairs. How many pairs of sneakers did Justin buy if he paid $135.78? Write a proportion and use cross products to solve for d, the number of sneakers that David bought
Answer:
6 pairs
Step-by-step explanation:
Since we are given a ratio/proportion problem and 3 values and 1 variable then we can use the Rule of three to solve this problem. We simply multiply the diagonal values available and divide by the 3 value to find the variable of the ratio like so...
4 pairs <======> $90.52
d pairs <======> $135.78
(4 * 135.78) / 90.52 = 6 pairs
Finally, we can see that Justin ended up buying a total of 6 pairs of sneakers.
