35300 tons of sugar beet we need in order to get 7,413 tons of sugar.

Step-by-step explanation:

Given that  in sugar beet, there is 21% of sugar.  Need to find out how much sugar beet we need in order to get 7,413 tons of sugar. Let we need x tone of sugar beet. So, according to the asked data, we have

                        21 \% \text { of } x=7413

                        (21)/(100) * x=7413

                        0.21 * x=7413

                        x=(7413)/(0.21)

                        x = 35300 tones

Evaluate the expression 6x-x2 for x= 0, 1, 2, 3, 4, 5, and 6. Use your results to fill in the table. Describe any pattern that you see.

Answers

assuming that x2=x^2 or x squared
so evaluate
basically subsitute values for x

0
6(0)-0^2
0-0
0

1
6(1)-1^2
6-1
5

2
6(2)-2^2
12-4
8

3
6(3)-3^2
18-9

6(4)-4^2
24-16
8

5
6(5)-5^2
30-25
5

6
6(6)-6^2
36-36
0

if we were to display the results on a table with the numbers we subsituted on the left and results on the right we would get
0,0
1,5
2,8
3,9
4,8
5,5
6,0

we notice that the outputs/results go up then down
the outputs were
0,5,8,9,8,5,0 when the inputs were
0,1,2,3,4,5,6

Can someone answer this for me pls and thank you

x in terms of b:

-2(bx - 5) = 16

-2bx + 10 = 16

-2bx =  6

    x = 6 / -2b

    x = -3/b

--------------------------------

when b = 3 then

-2(3x - 5) = 16

-6x + 10 = 16

-6x =  6

  x = -1

Answer

The value of x in terms of b is -3/b

The value of x when b is 3 is -1

How do i round 3,176 to the nearest thousand

Answers

Here is the rule: 4 and below let it go (round down), 5 and above give it a shove (round up)
Look to the place after the thousandths in the number 3,176 (the 1)
Since it is below 5, you would round down to 3,000
Well you would look at the 176 in 3,176. Since it is less then half (500) you would round it down. So 3,176 rounded to the nearest thousand would be 3,000
