Answer/Step-by-step explanation:
Ok so there is
3, 0-4 4, 5-9 2, 10-14 1, 15-19 1, 20-24
so you can get rid of the last one saying it has more than 1 number between 20-24.
The 3rd one has to short of numbers for 0-4.
the second one has way to many 0-4's when there should be 3 of them.
therefore your answer is The firstone.
Answer:
It’s the 2nd,3rd,and 4th

I just took the quiz
Answer:
A, C, and D.
Step-by-step explanation:
The other does not go through the origin, therefore it is not proportional.
The maximum number of microwave ovens the two employees can take on the elevator is 7.
<h3>How to find the maximum number of microwave ovens the two employees can take on the elevator?</h3>
To solve the question, we have to find the simple equation showing the relationship between all the weights an the maximum weight the elevator can carry
Let
- x = number of microwave ovens
Since the micro wave weighs 45 pounds, the total weight of microwave ovens is W = 45x.
Also, there are 20 televisions on the elevator. If each television weighs 85 pounds, the total weight of televisions is W' = 20 × 85 = 1700 pounds
Also, the weight of the equipment and the two employees is W" = 400 pounds.
Since the maximum weight on the elevator is 2400 pounds, we have that the required simple equation is
W + W' + W" = 2400
45x + 1700 + 400 = 2400
45x + 2100 = 2400
45x = 2400 - 2100
45x = 300
x = 300/45
x = 6.67
x ≅ 7
So, the maximum number of microwave ovens the two employees can take on the elevator is 7.

<span>1) force to pull it up 0.8 m
= 101.93 * 0.8
= 81.54 N
2) force for horizontal displacement
which can be found out by subtracting above value from total force applied
= 200-101.93
=98.07
Now finding horizontal displacement
98.07 = 101.93 * d
d= 0.96 m
Now since we found out hori. and vertical dist. apply Pythagoras theorem to find out length of ramp.
l^2= 0.96 ^2 + 0.8 ^2
= 0.9216 + 0.64
= 1.56
L = 1.25 m approx.</span>
