Umnica [9.8K]3 years ago

Answer: 480

Step-by-step explanation:

We can create a ratio for this!

We have:

\frac{number of hamburgers}{total students}= \frac{new number of hamburgers}{new number of students}

We can use substitution to input the information we already know:

\frac{12}{30} = \frac{x}{1200}

Using cross multiplication, we get:

1 200(12) = 30x

14,400 = 30x

\frac{14,400}{30}=\frac{30x}{30}

x = 480

Hope this helps! :)

Help I be trying so but can figure out the answer
Sphinxa [80]

Answer:

b

Step-by-step explanation:

Surface of the earth =3959×3.14

=12,437.565

if 20%is suitable so we multiply it by the surface

12,437.565×0.2=2,487.513 per people

2,487.513/7,700,00,00

So I think it will be the closest to b

Point K on the number line shows Kelvin's score after the first round of a quiz: In round 2, he lost 9 points. Which expression
weqwewe [10]

Complete question :

Point K on the number line shows Kelvin's score after the first round of a quiz: A number line is shown from negative 10 to 0 to positive 10. There are increments of 1 on either side of the number line. The even numbers are labeled on either side of the number line. Point K is shown on 3. In round 2, he lost 9 points. Which expression shows how many total points he has at the end of round 2? 3 + (−6) = −9, because −9 is 6 units to the left of 3 3 + 6 = −9, because −9 is 6 units to the left of 3 3 + (−9) = −6, because −6 is 9 units to the left of 3 3 + 9 = −6, because −6 is 9 units to the left of 3

Answer: 3 + (−9) = −6, because −6 is 9 units to the left of 3

Step-by-step explanation:

Given the following :

Width of number line = - 10 to + 10

Point K on the number line = +3 ( kelvin's score after the first round of quiz).

If Kelvin losses 9 points in round 2  = - 9

Hence at the end of round 2, He'll have a total of :

Point at the end of round 1 + point lost in round 2

3 + (-9) = - 6

If f'(x) = 12x^3 - 2x^2 - 17 and f(1) = 8 , find f(x).
Cloud [144]

Answer:

f(x) =  3x⁴ - \frac{2X^{3} }{3} - 17x +  \frac{68}{3}

Step-by-step explanation:

To find f'(x), we will follow the steps below:

We will start by integrating both-side of the equation

∫f'(x) = ∫(12x^3 - 2x^2 - 17)dx

f(x)  = 3x⁴ - \frac{2X^{3} }{3} - 17x + C

Then we go ahead and find C

f(1) = 8

so we will replace x by 1 in the above equation and solve for c

f(1)  = 3(1)⁴ - \frac{2(1)^{3} }{3} - 17(1) + C

8 = 3 - \frac{2}{3} - 17 + C

C =8 - 3 + 17 + \frac{2}{3}

C = 22 +  \frac{2}{3}

C =\frac{66 + 2}{3}

C = \frac{68}{3}

f(x) =  3x⁴ - \frac{2X^{3} }{3} - 17x +  \frac{68}{3}
