Hey!
So you have a net of the figure. It's broken into several 2D shapes. What you an do it find the area of each shape and add it together.
Triangles:
A = (b*h)/2
A= (5 * 3) / 2
A = 15/2
same thing for the second one
15/2 * 2 = 15
Don't forget, there are 2 triangles so it's really 15 for both
Rectangles:
A=b*h
A= 7*5
A=35
A=7*5
A=35
A=3*7
A=21
35+35+21=91
Now add the sum of the area of the triangles and the sum of the area of the rectangles
91+15 = 106
106 is the surface area
Hope this helps!
1/2, 4/8, etc. Because they all equal to one half. <span />
Answer:
£562.43
Step-by-step explanation:
£500 is invested for 3 years at a rate of compound interest of 4% per annum how much will be in the account after three years
Given data
P= £500
t= 3 years
r= 4%
The expression for the compound interest is given as
A= P(1+r)^t
substitute
A= 500(1+0.04)^3
A= 500(1.04)^3
A= 500*1.124864
A= 562.432
Hence the final amount is £562.43
Take the price of pears (£1.30 per kilogram) and multiply it by the amount of pears (7kg). You get 9.1 so now you take the total amount spent (£12.70) and subtract the 9.1 and you get 3.6 now that is the amount you spent on the apples. So take 3.6 and divide it by the amount of apples you got (2kg) you will get 1.8 and that is your overall answer.
18 = 2x + 4
2x = 14
x = 7
answer
first line: 1st box: 18 and 2nd box: 4
