James is 12 years old and his brother is 16. Which ratio represents James' age to his brother's age 4 years from now?
Answer:
16/20=1/4
Step-by-step explanation:
James is 1/4 younger then his brother
4:5 is the ratio which represents James' age to his brother's age 4 years from now.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that James is 12 years old
James brother is 16 years old.
We need to find the ratio which represents James' age to his brother's age 4 years from now.
After 4 years the James age is 12+4, 16 years
After 4 years the James brother age is 16+4, 20years
The ratio of James' age to his brother's age is 16/20
4/5
Hence, 4:5 is the ratio which represents James' age to his brother's age 4 years from now

Cecily claims that the equation y = mx + b, where b is a real number,
represents a function whose graph is a line. Which statement BEST
classifies this claim?
Cecily's claim is true only when b is zero.
Cecily's claim is true for all values of b.
Cecily's claim is not true for any value of b.
Cecily's claim is true only when b is not zero
Answer:
Cecily's claim is true for all values of b.
Step-by-step explanation:
Cecily's claim is true for all values of b.
If she graphs y = mx, and then y = mx + b, and then y = mx + c, and so on, she will find that her graphs are all straight lines that are parallel to each other (as they will all have the same slope, m).
A shooting star forms a right triangle with the Earth and the Sun, as shown below:
A right triangle is shown with the vertices labeled Earth, Sun, and Shooting Star. The angle formed by the Sun is labeled x deg
A scientist measures the angle x and the distance y between the Earth and the Sun. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star. (10 points)
NO LINKS OR ABSURD ANSWERS
The distance between the Shooting Star and planet Earth is equal to the distance between the Sun and the Shooting Star multiplied by the sine of angle x.
How to calculate the distance?Fist of all, we would assign variables to the distance between these astronomical objects as follows:
Let EM be the distance between the Shooting Star and planet Earth.Let y be the distance between the Sun and the Shooting Star.Since the triangle is right-angled, we would use the sine trigonometry to determine the value of the distance between the Sun and the Shooting Star:
Sinθ = Opp/Hyp
Sinθ = EM/y
EM = y × Sinθ
Therefore, the distance between the Shooting Star and planet Earth is equal to the distance between the Sun and the Shooting Star multiplied by the sine of angle x.

A jar contains black beads and green beads. Forty percent of the beads in the jar are green. A number generator simulates randomly selecting 10 beads from the jar. The number generator is used 12 times and the number of green beads in each trial is shown in the dot plot. Which description is correct about the number generator being fair or not? The number generator is not fair. The dot plot shows that 4 of 10 beads drawn are often green. The number generator is fair. The dot plot shows a distribution that is skewed right. The number generator is fair. It shows that 40% of the beads selected are green most of the time. The number generator is not fair. In most of the experiments, considerably less than 40% of the selected are green.
Answer:
The number generator is not fair. In most of the experiments, considerably less than 40% of the selected are green
Step-by-step explanation:
Given
[tex]Pr(Green) = 40\%[/tex]
See attachment for plots
Required
Is the number generator fair or not
From the number line, we have the following outcomes:
[tex]0 \to 1[/tex]
[tex]1 \to 1[/tex]
[tex]2 \to 7[/tex]
[tex]3 \to 2[/tex]
[tex]8 \to 1[/tex]
Divide each outcome by 12, to get the proportion of green in each trial
[tex]0 \to 1[/tex] [tex]\to 8.33\%[/tex]
[tex]1 \to 1[/tex] [tex]\to 8.33\%[/tex]
[tex]2 \to 7[/tex] [tex]\to 58.33\%[/tex]
[tex]3 \to 2[/tex] [tex]\to 16.33\%[/tex]
[tex]8 \to 1[/tex] [tex]\to 8.33\%[/tex]
The above shows that the proportion of green in most of the trial is less than 40%
Hence, the number generator is not fair.

You can transform ⨀A to ⨀A' by translating it and then performing a dilation centered at A'. Find the translation rule and the scale factor of the dilation
Simplify the scale factor and write it as a proper fraction, improper fraction, or whole number.
Translation: (x,y)↦ (____, ____)
Scale Factor: ____?
Answer: x=-10, y=-5 or -2/1. And it's dilated by 2. & i believe the scale factor is 2.
Step-by-step explanation:
What i did was simply count from the radius (the tiny dot in the center) up, and i counted 3, and did the same w/ the A' so I got 6, why makes me assume the scale factor is 2. then i did rise/run and i went 10 left and 5 down. So that makes -10,-5.

The function that represents the exponential graph is, [tex]y = 2^{x+2} + 3[/tex].
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
We know a function is called an exponential function when the exponent is the independent variable, For example, aˣ.
From the graph of the function, When x = 0, y = 7.
Observing the options we have,
[tex]y = 2^{x+2} + 3[/tex].
When x = 0.
[tex]y = 2^{0+2} + 3.[/tex]
[tex]y = 2^{2} + 3.[/tex]

Sara was choosing songs for her "Birthday Dance Party" shuffle tonight. She wanted to choose: 3 of her 8 Beyonce songs, 4 of her 12 Justin Timberlake songs, 2 of her 5 Drake songs, and finish it off with either Micheal Jackson or the Beatle's version of Happy Birthday. How many different ways can she make her Birthday song mix?
Answer:
554400
Step-by-step explanation:
To answer this question, we use combination as we are just interested in selection rather Than arrangement.
Beyonce songs ; 3 from 8 = 8C3
Justin ; 4 from 12 = 12C4
Drake ; 2 from 5 = 5C2
Version of happy birthday = 1 from 2 = 2C1
Recall :
nCr = n! ÷ (n-r)!r!
However, the answers can also be obtained using a calculator :

The Law of Sines works for any triangle and is given by [tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex] (the ratio of any angle and its opposite side is equal to the ratio of all other angles and their respective opposite sides).
Thus, we have:

A parent deposits $2000 into their child's bank account. The account earns 4%
interest each year. Write an explicit function that represents the situation. *
A(t) = 2000(1.04)-1
A (t) = 2000(4)'
A(t) = 2000(1.04)'
A(t) = 2000 + 4t
O
Answer:
A = 2000(1.04)^t
Step-by-step explanation:
Using the compound interest formula;
A = P(1+r)^t
P is the principal = $2000
r is the rate = 4% = 0.04
On substituting
A = 2000(1+0.04)^t
A = 2000(1.04)^t
Hence the required expression is A = 2000(1.04)^t

A squirrel moved 200 meters in 7,200 seconds. What was the speed of the squirrel in meters per hour? *
Answer:
100 meters per hour.
Step-by-step explanation:
7,200 seconds / 60 = 120 minutes
120 minutes / 60 = 2 hours
200 meters / 2 hours = 100 meters
Since the squirrel moved 200 meters in 2 hours, the squirrel moved 100 metres per hour.
