Answer:
[tex]k = 3[/tex]
Step-by-step explanation:
A function must put in a input to get that exact output.
This means that if we for example, put 8 in the function we must get out 2.
If we put in 3, we cant get 4 so
k=3 is the answer.

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What percent of the volume of the planet is the volume of its moon?
The volume of the planet's moon is % of the volume of its planet.
(Round to the nearest whole number as needed.)
Answer:
4%
Step-by-step explanation:
Volume of sphere
v = (4/3)πr^3
Volume moon/ volume planet
We don't actually need the numeric value of the radius
just the 35% ratio
Radius of moon = .35 radius of planet
Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3
Cancel like terms
Vm / Vp = .35^3
Vm / Vp = 0.042875
Expressed as a percentage
Vm / Vp = 4.2875%
Rounded
Vm / Vp = 4%
You are given a bag of jelly beans there are 7 red, 8 blue, 4 yellow, and 10 pink. Find the probability of drawing two blue in a row with replacement
Answer:
8 / 29 = .276
Step-by-step explanation:
29 is the total number of jelly beans
When we have replacement, we do not reduce the number of total jelly beans, so the probably of drawing blue stays the same.
Answer:
.276

has a y-intercept of (0,2) and passes through the point (3,128)
Answer:
y = 42x + 2
Step-by-step explanation:
The equation of a line is expressed as y = mx+b
Slope = y2-y1/x2-x1
Slope = 128 - 2/3-0
Slope m = 126/3
Slope = 42
Since the y intercept is (0, 2), hence b = 2
Get the equation;
Recall that y = mx+b
y = 42x + 2
This gives the required equation

Step-by-step explanation:
A bus departed from New York at 11 pm with 44 passengers. An hour later, a few passengers got off at New Jersey. The number of passengers who boarded the bus at New Jersey were twice the number of passengers who got off the bus. If the bus has 50 passengers now, how many passengers got off at New Jersey?
Answer:
6 got off at NJ
Step-by-step explanation:
if u write an equation it would be 44-x+2x=50. -x+2x=x so the equation would now be 44+x=50. If you subtract both sides by 44, it would be x=6. x was the number of people that got off at NJ so 6 people got off there.

Answer:
Option B = 5,881.96
Step-by-step explanation:
Volume of a sphere = 4π (r³/3)
If the diameter is 22.4, then the radius would be: 11.2 cm which is half of the diameter.
Therefore, the volume =
=> 4π (r³/3)
=> 4(3.14) (11.2³/3)
=> 12.56 * (1404.928/3)
=> 12.56 * 468.31
=> 5881.97
Therefore the approximation would be Option B = 5,881.96

what is the product of 3.4* 10^2 and 1.8* 10^3 expressed in scientific notation
Answer:
6.12 x 10⁵
Step-by-step explanation:
You just multiply 3.4 and 1.8 which gives 6.12
And for the notation you add the exponents 2 and 3 which give 5
Answer:
6.12 × 10^5.
Step-by-step explanation:
3.4 × 10² × 1.8 × 10³
To solve this, we can group.
[tex](3.4 * 1.8) * (10^2 * 10^3) =[/tex] [tex](6.12) *(10^5).[/tex]

Based on these results, which is the most reasonable
balls she will have blocked after 8 games?
A 96
B 32
C 72
D 56
Answer:
theanswer is D.72
Step-by-step explanation:
this.is because she blocked 36 balls in the first 4 games
As per the given data, it can predict that after 8 games the number of blocks would be 72 balls. Option c is correct.
Given that,
Based on these results, which is the most reasonable balls she will have blocked after 8 games is to be determined.
The average of the values is the ratio of the total sum of values to the number of values.
Here,
Average balls blocked in 4 games = 8 + 12 + 9 + 7 / 4 = 36 / 4
= 9
For the 8 games the number of ball blocked would be = 8 × 9 = 72
Thus, as per the given data, it can predict that after 8 games the number of ball blocks would be 72 balls. Option c is correct.

when we combine speed with direction indicated by the sign of the number, it is called velocity. True or False: this means that if you are moving 5 meters per second to the right, then your velocity is +5 meters per second?
What is the value of x ?
Answer:
x = 9°
Step-by-step explanation:
The full arc of the angles equals 360°. So, we can subtract all of the measures of angles we are given from the total 360 to find the value of x.
We can add the given angles together and subtract the sum from 360 as well.
73 + 63 + 89 = 225
This means the measure outside 15x is a combines 225°.
Now, subtract the known measures from our total, 360.
360 - 225 = 135
The unknown, or 15x, is equal to 135°.
15x = 135
Solve this like a normal equation. Divide both sides by 15 to isolate x and solve for the variable.
[tex]\frac{15x}{15}[/tex] = [tex]\frac{135}{15}[/tex]
x = 9
x is equal to 9°.
We can check by adding all our values together again to see if they amount to 360°.
73 + 63 + 89 + 15(9) = 360
360 = 360
The equation is correct, so we can be sure that we are right.
The answer is x = 9°.

Step-by-step explanation:
8 > 2 - x/3
Multiply the equation by 3.

Flip around to make working with it easier.
6 - x < 24
Subtract 6 from both sides.
-x < 18
Divide by -1. When dividing by a negative in an inequality, flip the sign.
