Answer:7
Step-by-step explanation:
This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....
Also the 3 has a recurring symbol above it
The 7 is times seven so uh yeah<3
We see nothing below that makes the situation clear for us.
We have no way to know what the angles 'x' and 'y' are, or
even whether they're on the same planet as the circle.
Answer:
A = 1,307 cm^2
Step-by-step explanation:
Formula of Surface Area of a Rectangle:
A = 2 (lw + lh + wh)
length*width = (20)(23) = 460
length*height = (23)(4.5) = 103.5
width*height = (20)(4.5) = 90
A = 2 (460 + 103.5 + 90)
A = 2(653.5)
A = 1,307 cm^2
well the formula i came up with is the t=time d= drove and r=rate
youre trying to find the Time, so therefore the beginning of the equation is t= ?? so theres a lil hint :)
