Answer:
Step-by-step explanation:
5 3/4 + 2 1/2
Add the whole numbers first
5 + 2
Add the fractions next
3/4 + 1/2 = 3/4 + 2/4 = 5/4 = 1 and 1/4
The total is
7 + 1 1/4 = 8 1/4
The answer is 75 % you just have to divide 84 and 112 and u get 75%
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
Answer:
y = 8x
Step-by-step explanation:
The equation for any straight line is y= bx + c
b is equal to the gradient, meaning you have to draw a triangle (like in the image above)
You then divide 8 by 1 to get you the gradient which is what goes in front of x.
c is the y intercept which is where the line crosses into the y axis. In this case it is zero.

Since the place just to the right of the decimal is the tenth, we look at the digit to the right of it & if it is 5 or higher, we'll round up. If it's 4 or less, we'll leave it as is (taking out the hundredth place, or the digit to the right). Hope this helps!
