Hi!
If you're given a net and measurements like this, then you can take it part by part to figure out the area of all the different shapes you're given and add it all together.
I'm going to first do the two triangles. The two have the same measurements, 6 by 8, and since there are two of them, you can combine the two. The formula for the area of a triangle is 1/2bh, and since there are two, you can make it 2 * 1/2bh. The 2 cancels out with the 1/2, and you just get bh.
The base, I'm just going to set 8 equal as it, and 6 as the height. 8 * 6 = 48, so the area of the two triangles is 48 cm squared.
Now to find the area of the rest. Since they all have a dimension of 15 cm, you can add together their other dimensions, and just multiply it all together.
6 + 8 + 10 = 24 cm
Now just multiply base * height, or 24 * 15. 24 * 15 = 360 cm squared.
Now add the two together. 360 + 48 = 408 cm squared.
Hope this helped!
Answer:
I would say a becuase you have a better chance to get heads then a five on a number cube
Step-by-step explanation:
1 nickel = 5 cents
1 dime = 10 cents
The total = $2.40
There’s a total of 30 coins.
12 nickels = $0.60
18 dimes = $1.80
Isabelle has 12 nickels.
Suppose, initially the ladder is so close that height of the ladder, which is 10 m to the point at which its upper end has reached.
When we pull the bottom of the ladder to such a place that it has come down by 7 m and its upper end is now 3 m from the ground. If we take the base y m, then
Using Pythagorus theorem,
y2 = 10^2 - 3^2 = 100 - 9 = 91
y = 9.54 m
The speed by which ladder was pulled was 2 m/min
So time taken to cover 9.54 m woulds be 4.77 min
As the ladder has come down by 7 m in 4.77 min, its speed for coming down was 7/4.77 = 1.47 m/min
