What is the solution to the proportion 42 over 56 equals 12 over x ? x =_______

1 answer:

3 0

42 12
—- = —-
56 x

Simplified:

3 12
— = —-
4 x

Multiply both sides by 4:

3 = 48
—-
x

Multiply both sides by x:

3x = 48

Divide both sides by 3:

x = 16

The position of a particle moving to the right on the x-axis is given by x(t), where x(t) is measured in inches and t is measure

wlad13 [49]

Answer:

No options

Step-by-step explanation:

Knowing that V=in/min = x(t)/t and according to the graph,

V=20in/20min=in/min, so

No options since speed is not inches per minute, spedd (V) = inches over minutes

Computing if a computer can do one calculation in 0.0000000015 second, then the function t(n) = 0.0000000015n gives the time req

Lelechka [254]

Answer:

t(5,000,000,000) = 7.5 sec

Explanation:

A computer take 0.0000000015 sec to do a calculation.

Given a function t(n) = 0.0000000015n

where n represent the number of calculation.

We need to find the total time computer to do 5 billion calculations.

We plug n = 5 billion = 5,000,000,000

Total taken time t(n) =0.0000000015n

t(5,000,000,000) = (0.0000000015)*(5,000,000,000)

t(5,000,000,000) = 1.5*5

t(5,000,000,000) = 7.5 sec

That's the final answer.

I hope it will help you.

Every morning, a deli offers a “commuter special” in which customers can select a pastry, beverage, and a copy of one of the loc

mars1129 [50]

To find the number of possible combinations, you multiple the possible number of outcomes for each category together. For example, there are 5 choices of pastries, 4 choices of drinks, and 2 newspaper choices, so normally there are 5 x 4 x 2=40 possible combinations. Without a muffin, these numbers would change to 4 x 4 x 2=32. The difference would be 8 possible options, so choice C.

The function f(x)=tan(3/2x-pi/2) has:

zlopas [31]

I think the best option here is B. <span>period 2pi/3 and asymptote at x=0
</span>because period of tanx is pi so period of tan(3/2x) is pi/(3/2) = 2pi/3. I hope this can work good for you.

The graph shows the level of ibuprofen, y units, in a patient’s bloodstream x hours after the ibuprofen was taken. Select the co

ElenaW [278]

The graph is missing, so i have attached it.

Answer:

From 0 hours to 2 hours.

Step-by-step explanation:

From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.

Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.

After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.

Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.
