Answer:

2250

Step-by-step explanation:

We have, 14% × x = 315

or,

14

100

× x = 315

Multiplying both sides by 100 and dividing both sides by 14,

we have x = 315 ×

100

14

x = 2250

If you are using a calculator, simply enter 315×100÷14, which will give you the answer

Answer:

2250

Step-by-step explanation:

Let x be the number

14% of x = 14/100 * x

14/100 * x = 315

Multiply 100 on both the sides,

14x = 31500

Divide by 14 on both the sides,

x = 31500/14 = 2250

A box of cereal states that they are 72 cal in a 3/4 cup serving. What is the calories per cup? How many calories are there in 4
Illusion [34]

Answer:

The answer is simple, you have 72 calories as 3/4 of a cup. So you calculate 1/4 of a cup by dividing 72 by 3. We get 24, now we get a total of 96 calories in one cup. Now we have 96x4 which is 384.

An arithmetic sequence is shown below. You are not given many terms of this sequence, but you do have enough to fill in the miss
kicyunya [14]

Answer:

B.35

Step-by-step explanation:

The sequence is

14, ,56,....

14 , x , 56

Think of it as 14 + d = x

x+ d = 56

d is the common difference

We now have 2 equations and 2 unknowns

Substitute the first equation in for x   into the second equation

x+d =56

(14+d) +d = 56

Combine like terms

14 + 2d = 56

Subtract 14 from each side

14-14 + 2d = 56-14

2d = 42

Divide by 2

2d/2 =42/2

d = 21

The common difference is 21

Now we can find x

14 + d = x

14+ 21 = x

35 =x

The unknown term is 35

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.
andrey2020 [161]

Answer:

Hey! The answer is 25,4 centimeters.

Step-by-step explanation:

In a linear function you can use y=mx+n

So if x = hours and y= height.

You know that

\left \{ {{27,8=11m +n} \atop {24,8=26m +n}} \right.

So:

If you multiply (24,8=26m +n) x-1

It is: -24,8 = -26m -n

Adding up the other equation

-24,8 = -26m -n

<u>27,8 = 11m + n</u>

<u>3 = -15m</u>

<u>m= -0,2</u>

So

27,8 = 11 x 0,2 + n

27,8 = -2,2 + n

30 = n

This results that te linear function for this equation is:

y = -0,2x + 30

The answer is

y=23(-0,2) + 30

y=-4,6+30

y=25,4
