Answer:
AB = 5
Step-by-step explanation:
The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be √3 times as long, and the side opposite the 90 degree angle will be twice as long.
In this case we just divide 10 by 2
I think the answer is 22mn2+66m2n-64 since there are no more like terms
Answer:
Question 1 = c) Medium: 88 ft²
Question 2 = d) 46.7 ft³
Step-by-step explanation:
Question 1
We would be solving this question by finding the surface area of the tent. The shape of the tent is a square based pyramid.
The surface area of a square based pyramid(tent) =
a² + 2ah
Where in the diagram,
a = base length = 4 ft
h = height of the pyramid (tent ) = 9ft
Surface area = 4² + 2 × 4 × 9
= 16 + 72
= 88ft²
Therefore, the size tarp should she purchase is Medium: 88 ft²
Question 2
For question 2, from the attached diagram, we can see that the diagram is a square based pyramid.
To calculate the amount of water that would fill the square based pyramid, we would have to find the Volume of the tent(square based pyramid).
The formula for the Volume of the tent(square based pyramid) = 1/3(a²h)
Where a = base edge
h = height of the pyramid.
From the diagram,
a = base edge => 4ft.
From the question,
h = height of the tent is given as how tall the tent is = 8.75ft.
Therefore, 1/3(a²h)
1/3 × (4ft)²× 8.75ft
= 46.67ft³
Approximately = 46.7ft³
Therefore, the amount of water it would it take to fill the tent, if the tent is 8.75 ft tall is 46.7ft³
so 253 doubles is 506, 506 divided by two = 253
therefore the answer will be '' 506 divided by 2 = 253''
Answer:
1. 1,016 sq. m.
2. 119 sq. m.
Step-by-step explanation:
1.
14 x 18 = 252
18 x 8 = 144
14 x 8 = 112
2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )
504 + 288 + 224 = 1,016 sq m
2.
4 (7 x 5 divided by 2) + (7 x 7) =
7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.
I hope this helps
sorry if i'm wrong
