Interpreting Points on Graphs of Proportional Relationships

Mathematics
1 answer:
HACTEHA [7]1 year ago
5 0

There are the following conclusions:

Not true

  1. The pumpkin grew to a weight of 3 ounces in 18 weeks.
  2. The quotient 3 / 18 equals the growth rate of the pumpkin in ounces per week.

Cannot be determined

  1. Each crate can hold 18 pumpkins.

True

  1. In 3 weeks, the pumpkin grew to a weight of 18 ounces.
  2. The pumpkin grew at a rate of 6 ounces per one week.

<h3>How to interpret graphs of proportional relationships</h3>

The graph shows the graph of proportional relationship, in which the weight of a pumpkin, in ounces, is directly proportional to time, in weeks. Then:

y ∝ x

y = k · x

Where k is the constant of proportionality, in ounces per week.

The point (x, y) = (3, 18) indicates that a pumpkin reaches a weight of 18 ounces after 3 weeks and the constant of proportionality is equal 6 ounces per week.

Then, we have the following conclusions:

Not true

  1. The pumpkin grew to a weight of 3 ounces in 18 weeks.
  2. The quotient 3 / 18 equals the growth rate of the pumpkin in ounces per week.

Cannot be determined

  1. Each crate can hold 18 pumpkins.

True

  1. In 3 weeks, the pumpkin grew to a weight of 18 ounces.
  2. The pumpkin grew at a rate of 6 ounces per one week.

Water level in a well was 20m below ground level. During rainy season, rainwater collected in different water tanks was drained
IgorC [24]

Answer:

17 m

Step-by-step explanation:

As shown in the figure,  A_0-B_0 is the ground level, A_1-B_1 is the old level of water which was at 20 m below ground level, A_2-B_2 is the new level of water which is 5m above of old level. The height of wall of the well, 1.20 m, and the the pelly at 80 cm =0.80 m, has been shown too.

The minimum length of the rope is equal to the distance between the pully and the new water level, indicated by the length L_0 in the figure.

So, L_0= 20-5+1.20+0.80= 17m

Hence, Raghu must use a rope having the minimum length 17 m to draw water from the well.

If an object is dropped from a height of 144 feet, the function h(t)=-16t^2+144 gives the height of the object after t seconds.
shtirl [24]

Answer:

A. 3s

Step-by-step explanation:

The height of the object after t seconds is given by:

h(t) = -16t^2 + 144

When will the object hit the ground?

It hits the ground after t seconds, and t is found when h(t) = 0. So

h(t) = -16t^2 + 144

0 = -16t^2 + 144

16t^2 = 144

t^2 = \frac{144}{16}

t^2 = 9

t = \sqrt{9}

t = 3

3 seconds, so the correct answer is given by option a.

If x+9.8=14.7, what is the value of 8(x-3.7?
yulyashka [42]
First find X by subtracting 9.8 from 14.7
X should equal 4.9
than fill in the equation for x
8(4.9-3.7)
you then subtract in the parenthasis
getting the answer of 1.2
finally multiply 1.2x8
Your final answer is 9.6
