What percent of 200 is 28

Mathematics
2 answers:
Dafna1 [17]3 years ago

1. We assume, that the number 200 is 100% - because it's the output value of the task. 
2. We assume, that x is the value we are looking for. 
3. If 200 is 100%, so we can write it down as 200=100%. 
4. We know, that x is 28% of the output value, so we can write it down as x=28%. 
5. Now we have two simple equations:
1) 200=100%
2) x=28%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
200/x=100%/28%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 28% of 200


<span>x=56
</span>
so <span>now we have: </span>
<span>28% of 200=56</span>

green pepper, onion, tomato

= 2x, 5x, 9x

Number of cups = 96

therefore 2x + 5x + 9x = 96

16x=96

x= 96÷16 = 6

Onion = 5x

therefore answer = 6 x 5 = 30

C. 30 is the correct answer :)

The graph of f(x) = 2x + 3 shifts 10 units to the right when it is replaced with the graph of f(x) = 2x − k. What is the value o
Nezavi [6.7K]

Answer:

k=17

Step-by-step explanation:

Given F(x)=2x+3  shifts 10 units when it is replaced with the graph f(x)=2x-k.

The method to solve this kind of questions is find where the graph meets the x axis then add ten units to it .The obtained x coordinate is the point where the second graph meets the x axis.

Now first find where the F(x)=2x+3 meets the x axis by substituting F(x)=0.

2x+3=0

x=-\frac{3}{2}

Now add 10 to this x coordinate , we get x1=10-3/2=17/2

this is x coordinate where the second line meets the x-axis.

The second line is F(x)=2x-k.

now f(x)=0 and x=17/2

On substitution we get 0=2*17/2-k

k=17

Sonbull [250]

Answer:

F(x) = 6x + 5.

Step-by-step explanation:

Given that :

Number of cards Given to Sébastian = 4

Number of baseball cards purchased every month = 6 cards

Number of months = x

Linear function f(x) which shows the number of cards after a number of months:

(Number of cards produced per month * Number of months) + number of card `

F(x) = 6x + 5

This handy application of LCMs is used by astronomers. All the planets in our solar system revolve around the sun. The planets o
TiliK225 [7]

To find number of years we take LCM of planets revolution times.

Planet's revolution times are given in the chart

Solar System Planet Revolution Time

Earth 1 year

Mars 2 years

Jupiter 12 years

Saturn 30 years

Uranus 84 years

Neptune 165 years

We take LCM of 1,2,12,30,84 and 165

Prime factorization of 2 = 2

Prime factorization of 12 = 2^2 * 3

Prime factorization of 30 = 2 * 3* 5

Prime factorization of 84 = 2^2 * 3 * 7

Prime factorization of 165 = 3*5*11

We take set of prime factors that has highest exponent,

So LCM = 2^2 * 3 * 5 * 7 * 11 = 4620

Therefore it will take 4620 years.
