Answer:
what do you need help with?
2.8 X 10^-8 (........characters space so that I can post this..)
First, you subtract 8 by both sides ( 8-8/ 20-8) so now your equation is 3n=12. Next, you multiply 3n by 3, and get 0, and 12 multiplied by 3 and the answer is 36! Hope this helped.
Answer:
Height of the kite is
meters.
Ground distance from the kite to the person flying the kite is 50 meters.
Step-by-step explanation:
Given that a string of a kite is 100 meters long and it makes an angle of 60° with horizontal.
Which mans we are getting a shape of right angle triangle as shown in picture. Where "y" is the height of the kite and "x" is the ground distance from the kite to the person flying the kite. Now we can use trigonometric ratios to find the values of x and y.
![\sin\left(60^o\right)=\frac{\left[opposite\right]}{\left[hypotenuse\right]}=\frac{y}{100}](https://tex.z-dn.net/?f=%5Csin%5Cleft%2860%5Eo%5Cright%29%3D%5Cfrac%7B%5Cleft%5Bopposite%5Cright%5D%7D%7B%5Cleft%5Bhypotenuse%5Cright%5D%7D%3D%5Cfrac%7By%7D%7B100%7D)




Hence height of the kite is
meters.
similarly:
![\cos\left(60^o\right)=\frac{\left[adjcent\right]}{\left[hypotenuse\right]}=\frac{x}{100}](https://tex.z-dn.net/?f=%5Ccos%5Cleft%2860%5Eo%5Cright%29%3D%5Cfrac%7B%5Cleft%5Badjcent%5Cright%5D%7D%7B%5Cleft%5Bhypotenuse%5Cright%5D%7D%3D%5Cfrac%7Bx%7D%7B100%7D)




Hence ground distance from the kite to the person flying the kite is 50 meters.
Answer:
80
4
Step-by-step explanation:
You are correct in placing 80 in the box in the table. If you examine the table and the pattern, you'll see that as the number of marbles increases by 10, the weight of the bags increases by 40.
We can determine the rule by dividing 40 by 10: 40 ÷ 10 = 4.
So, the rule is actually to divide the weight of the bag by 4 to find the number of marbles.
Note that this is likely because each marble is 4 grams.
