Answer:
a < 3
Step-by-step explanation:
divide both sides by -3
so -3/-3 = a
-9/-3 = 3

Select the correct answer from each drop-down menu. The velocity, v, in meters/second, of an object with a mass of m, in kilograms, and kinetic energy of K, in joules, is given by this equation. Use the equation to complete this statement. The kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second is joules.
Answer:
25
Step-by-step explanation:
The kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules
Calculating Kinetic energyFrom the question, we are to determine the kinetic energy of the ball
From the given equation for the velocity,
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
We will make K the subject of the equation
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
Take the squares of both sides
[tex]v^{2} ={\frac{2K}{m} }[/tex]
Multiply both sides by m
[tex]mv^{2} ={\frac{2K}{m} } \times m[/tex]
[tex]mv^{2} =2K[/tex]
∴ [tex]K = \frac{1}{2} mv^{2}[/tex]
Now, for the kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second
That is,
m = 2 kg
and v = 5 m/s
Putting the parameters into the equation, we get
[tex]K = \frac{1}{2} \times 2 \times 5^{2}[/tex]
K = 25 J
Hence, the kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules

Question 15
Consider this set of ordered pairs: {(-2,-1), (2,1), (1,5), (-2,4)}. What is the range?
A
{-2, 1, 2}
B
All Real Numbers
С
{-1, 1,4,5)
D
{-2,-1, 1, 2, 4, 5)
Answer:
Option (C)
Step-by-step explanation:
Domain of a function is a set of x-values (input values) of the function.
Similarly, Range of a function is a set of y-values (output values).
Given set of ordered pairs is {(-2, -1), (2, 1), (1, 5), (-2, 4)}.
Domain → {-2, 2, 1, -2}
Range → {-1, 1, 4, 5}
Option C will be the correct option.

Jason needs to save at least $200 by the end of the summer. He already has $40, and he has 8 weeks to save. Which inequality can he use to decide how much he needs to save each week?
Step-by-step explanation:
y=mx+b
200 = 8x + 40
Rearrange,
x = 160/8 = 20
He would need to save $20 a week
200= 20 × 8 + 40
Answer:
8x + 40 ≥ 200At least $20 each weekStep-by-step explanation:
Target amount = at least $200Jason already has = $40Time = 8 weeksSaved amount each week = xRequired inequality:
8x + 40 ≥ 2008x ≥ 160x ≥ 160/8x ≥ $20Which transformation takes ABCD to A’B’C’D?

2x 22/7 x 35 x 100
Plz tell me fastttt
Answer:
22000
Step-by-step explanation:
[tex]2 \times \frac{22}{7} \times 35 \times 100[/tex]
35 is divisible by 7. So reducing 35 by 7 gives 5.
[tex] = > 2 \times 22 \times 5 \times 100[/tex]
Lets multiply 2 & 5 for making the calculation easy.
[tex] = > 22 \times 10 \times 100 = 22000[/tex]
4(2x−3)= 28 solve for x
Answer:
5
Step-by-step explanation:
multiply
8x - 12 = 28
add 12 to both sides
8x = 40
divide
5
Answer:
Start with what we know:
4(2x-3) = 28
Now we do rainbow property aka distributive property:
4*2x=8x
4*-3=-12
now we have:
8x - 12 = 28
we have to get 8x alone:
we will add 12 to both sides:
8x= 40
now we have to get x alone:
8x/8=x
40/8=5
now we put that into a equation:
x=5

If there are 40 boys and 60 girls in a room, fill out all of the possible ratios of boys to girls that could be made.
40+60=100. So one person equals 1%, meaning 40% are boys and 60% are girls. By simplifying, we will find that possible ratios below the value of 100 are 40:60, 4:6, 2:3, and 20:30.
Answer:
40:60 or 60:40
Step-by-step explanation:
This is the answer because a ratio looks like this
#:# <that just means a number by a number
and since the question is telling you to fill out all of the possible ratios of boys to girls that could be made.
There is really only one way you can write boys to girls but since they saying this try flipping the answer around like this: 60:40

Una inversión de $$4250 produce $125 de rédito en u
año, ¿cuánto producirán $10200 a la misma tasa de
interés?
Answer:
The correct answer is $300
Step-by-step explanation:
According to the given scenario, the computation of the interest produced is shown below;
Given that
The investment of $4,250 produced $125 return
So for $10,200 the return would be
= (Production × return) ÷ (investment made)
= ($10,200 × $125) ÷ ($4,250)
= $300
Hence, the interest produced is $300

Answer:
93
Step-by-step explanation:
the total of all those are 150 so if you multiply it by three you get 450
so multiply pizza by three too
to get 93
Answer:
93 students
Step-by-step explanation:
You first need to add up all the numbers on the chart, 36 + 29 + 54 + 31. You would then get 150. Divide 450 / 150 = 3. You multiply the amount of students chose pizza by 3 and you get 93. 31 * 3 = 93.
Therefore, 93 students would say pizza is there favorite food.
