Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

The three ratios that would form a proportion with the ratio of 5/3 are,

(5×2)/(3×2), (5×3)/(3×3) and (5×4)/(3×4).

Write an equation and show your work: There were five different Foil Kites that each descend 50 feet per second for 5 seconds. Find the total change in altitude for all 5 kites.

Answers

Answer: Change in altitude = (50 x 5) feet

The total change in altitude for all 5 kites. = 250 feet

Step-by-step explanation:

Given : Rate of descent = 50 feet per second  (speed)

Time = 5 seconds

Since, distance = speed x time

Change in altitude = Rate of descent x Time

Change in altitude = 50 x 5 feet  [required equation]

= 250 feet

Hence, the total change in altitude for all 5 kites. = 250 feet

A cat can travel a distance of 32.5 meters in 13 seconds. What is the average speed of the cat to the nearest hundredth of a m/s? *

A 2.5 mph

B 0.4 mph

C 2.5 m/s

D 0.4 m/s

Answers

Answer:

C. 2.5 m/s

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex]

[tex]S = \frac{d}{t}[/tex]

Given the following data;

Distance = 32.5m

Time = 13secs

Substituting into the above equation;

[tex]S = \frac{32.5}{13}[/tex]

Speed, S = 2.5m/s

Diana is comparing the membership costs at two fitness centers. The community fitness center costs $60 per month. The fitness center located where she works has a $100 registration fee and costs $40 per month. After how many months of membership will the costs be the same? 2 3 4 5

Answers

Answer:

The indifference point is 5 months.

Step-by-step explanation:

First, we need to structure the total cost formula for each fitness center:

Community center= 60x

Work center= 100 + 40x

x= number of months

Now, we equal the formulas and isolate x:

60x = 100 + 40x

20x = 100

x= 5

The indifference point is 5 months.

If -4 is a solution of the equation f(x) = 2, which must be the coordinates of a point on the graph of f?
(4,-2)
0 (-2,4)
O (2,-4)
O (-4, 2)

Answers

the answer is (-2,4) (:

The coordinates of the point on the graph of is (-4,2).

What is a function?

A function is defined as the relationship between input and output, where each input has exactly one output. The inputs are the elements in the domain and the outputs are elements in the co-domain.

If -4 is a solution of the equation f(x) = 2,

When giving the input as  -4 the output will be 2.

Thus these can be written in ordered pair as (-4,2).

Hence, the coordinates of the point on the graph of is (-4,2).

Find the value of y for which the value of 8y+3 is 7 more than the value of 6yTom and Sam can finish a plowing job in two hours if they work toghether. Tom working alone can do the job in 7 hours. How long would it take Sam to finish the same job alone?

Answers

Answer:

19 ; 2.8 hours

Step-by-step explanation:

Find the value of y for which the value of 8y+3 is 7 more than the value of 6y

8y + 3 = 7 + 6y

8y - 6y = 7 - 4

2y = 3

y = 3/2

y = 1.5

Let

Tom's rate = x

Sam's rate = y

Rate = 1 / time

Hence,

x = 1/7

Rate when they work together = 1/2

Tom's rate + Sam's rate = 1/2

1/7 + y = 1/2

y = 1/2 - 1/7

y = (7 - 2) / 14

y = 5/14

Since, rate = 1/time

Time = 1/ rate

Sam's time = 1/ rate = 1/y = reciprocal of y

Sam's time = 14/5 = 2.8 hours

2.8 hours = 2 hours (0.8 * 60) = 2 hours 48 minutes

cupcake, and the total cost of the order was $53.50. What was the price of each cupcake?

Answers

Answer:

$1.50

Step-by-step explanation:

The total cost was $52. Subtracting out the cost of the layer cake ($16) leaves us with $36 to pay for the 24 cupcakes.

 

This means that each cupcake must have cost $1.50 ( = $36 / 24 cupcakes )
