Answer:
Race completed in 48 minutes.
Step-by-step explanation:
Let the speed of Max on hoverboard is = x
Then as per question speed of Victoria on hoverboard = 3x
Now it has been given in the question that speed of Victoria on foot is 1/3 of the speed of Max on hoverboard that will be = x/3
Now we will form the equation.
As we know the formula speed = distance/time
Let the time taken by both to complete the race be t minutes.
Distance covered by Victoria in 12 minutes + Distance covered by Victoria on foot = distance covered by Max on hoverboard
Then the equation will be
12(3x)+(1/3)x(t-12)=xt
So 48 minutes it took to complete the race.
3000 Quick answer
Let your calculator do the work. Be careful how you enter this in. (Are you supposed to estimate it? We'll get around to that.) Write it like this.
1.2 * 10^3 divided by 4 * 10^-1 Your calculator will do this nicely. The trick is the - 1. Put it in the calculator like this.
1.2
*
10
^
3
=
÷
4
*
10
^
(-1)
= The calculator should read 3000
That's one way to do it. Another way is just to do it all by hand. The numbers are easy enough
1.2 * 10^3 means shift the decimal 3 places right. 1 200 which is 1200
4 * 10^-1 can be handled 2 ways 10 to the minus 1 in the denominator becomes 10^1 in the numerator. Notice the sign change on the 10 when you shift if :it becomes plus! That's why you did it.
1200 * 10^1
12000
Now you are still left with 4 in the denominator.
12000/4 = 3000.
The first method always works. The second one gives you a better understanding of how powers work. There are other ways of doing this, but these are the two best, I think.
Answer:
8)55°
9)35°
10)55°
11)69°
12)64°
Step-by-step explanation:
8)180-125=55
9)90-55=35
10)180-125=55
11)180-111=69
12)45+69=116
180-166=64
Y= -35
Y = -1
I put the work in the picture below!
(Hint: just substitute the x for its number and do simple adding and subtracting)
Answer:
<h2>25m²</h2>
Step-by-step explanation:
If you want to find the area, you have to use this formula:
Formula:
LxW
L: length
W: Width
Here we have a square, and the sides are all 5 meters long, that means that we have to just do 5x5 to get the answer.
5x5=?
Hope ya remember the 5 table, lol, I know everyone does
5x5=25
so hence, your answer is 25m²
Thanks!
