An 80 metre long train crosses a 120 metre long platform in 20 seconds, what is the speed of the train per hour?

ans:
Total distance= length of train + length of platform

I.e 80+120= 200 m but need in kmph so 0.2 km

Time = 20 second but need in hours so 20/(3600)= 1/(180)

Speed = distance / time = 0.2*180= 36 kmph

Step-by-step explanation:

4. The revenue from each of x cupcakes is 2.50, so the total revenue from cupcake sales is 2.50x.

The revenue from each of y cakes is 15.00, so the total revenue from cake sales is 15.00y.

The total revenue from sales of cupcakes and cakes is more than 510, so we can write the inequality ...

2.5x +15y > 510 . . . . possible combinations of cakes and cupcakes

5. For x=144 the constraint on y is ...

2.5(144) +15y > 510

360 +15y > 510

15y > 150

y > 10 . . . . possible number of cakes sold

19. The velocity of an object fired directly upward is given by V = 35 – 9.8t, where t is time in seconds. Which inequality describes the velocity when t is between 0.5 and 1.5 seconds? (HINT: Remember that when you multiply an inequality by a negative number, you must switch the direction of the inequality.)
A. 20.3 > 35 - 9.8t > 30.1
B. 4.9 > t > 14.7
C. 0.5 35 - 9.8t > 4.9
D. V < 30.1
E. 20.3 < 35 - 9.8t < 30.1
F. 14.7 > 35 - 9.8t > 4.9

Answers

Answer:

20.3 < 35 - 9.8t < 30.1

Step-by-step explanation:

Given the Velocity model:

V = 35 – 9.8t ; t = time in seconds

V when t is between 0.5 and 1.5

V when t = 0.5

V = 35 - 9.8(0.5)

V = 35 - 4.9 = 30.1

Vt=0.5 = 30.1

V when t = 1.5 ;

V = 35 - 9.8(1.5)

V = 35 - 14.7 = 20.3

Vt= 1.5 = 20.3

Hence V, between, t = 0.5 and t = 1.5

Vt=1.5 < V < Vt=1.5

20.3 < V < 30.1

V = 35 - 9.8t

20.3 < 35 - 9.8t < 30.1

Titus took 30 minutes to walk 2 miles at a constant rate. Let d represent the distance Titus walks in miles after t minutes. What are two different constants of proportionality for the relationship between distance, in miles, and time, in minutes?

Answers

Answer:

15 and 1/15

Step-by-step explanation:

Given

Time (t) = 30 minutes

distance (d) = 2 miles

To determine the first constant of proportionality

Let time be directly proportional to distance.

t = kd

Where k is the constant of proportionality

Make k the subject

k = t/d

Substitute values for t and d

k = 30/2

k = 15

To determine the second,

Let distance be directly proportional to time.

d = kt

Make k the subject

k = d/t

Substitute values for d and t

k = 2/30

k = 1/15

Hence, the constant of proportionality are

15 and 1/15

While mining, Jason found a large metal bar that weighed 50 ounces. Jason was also able to determine that the bar contained 60% nickel. How many ounces of nickel are in the metal bar?

Answers

Answer:

The answer is 30

Step-by-step explanation:

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

If 60% of nickel is present in the metal bar that weighs 50 ounces.

The amount of ounces of nickel in the metal bar is 30 ounces.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% of 100 = 50/100 x 100 = 50

20% of 40 = 20/100 x 40 = 8

We have,

Weight of the metal bar = 50 ounces.

The percentage of nickel in the metal bar = 60%

The amount of nickel in the metal bar:

= 60% of 50 ounces

= 60/100 x 50 ounces

= 30 ounces

Thus,

If 60% of nickel is present in the metal bar that weighs 50 ounces.

The amount of ounces of nickel in the metal bar is 30 ounces.

A backpack will hold 2,808 grams. If a T-shirt weighs 156,000 milligrams, how many T-shirts will the backpack hold?

Answers

Answer:

18 T-shirts

Step-by-step explanation:

1gram = 1000milligrams

1gram × 156000milligrams ÷ 1000milligrams

The milligrams unit cancel out each other thus grams remains as the main unit.

=156grams

1 T-shirt = 156grams

1 T-shirt × 2808grams ÷156grams

The grams unit cancel out each other thus T-shirt remains as the main unit.
