For this you would want to break this figure up with familar shapes. You can do two triangles and one big rectangle.
First triangle:
(3)(2)(1/2)= 3 feet squared
Second Triangle:
(3)(4)(1/2)= 6 feet squared
Rectangle:
(11)(3)= 33 feet squared
Now you add:
33+3+6= 42 feet squared
So, for this hole you will need 42 feet squared of outdoor carpet
Answer:
your answer is A. 92.4
Step-by-step explanation:
Diagonal Length = v(92.4² + 50²)
V(8537.76 + 2500)
V(1037:76)
Diagonal Length 105
There are 23 sharks and 7 octopi in the aquarium
- Let the number of sharks in the aquarium be x
- Let the number of octopi in the tank be y
If the total number of animals in the tank is 30, therefore;
- x + y = 30 ....................... 1
If the total number of legs in the tank is 171 with starfish having 5 legs and Octopus having 8 legs, the required expression will be:
- 5x + 8y = 171 ................ 2
From equation 1, x = 30 - y ................... 3
Substitute equation 3 into 2 to have:
5(30-y) + 8y = 171
150 - 5y + 8y = 171
3y = 171 - 150
3y = 21
y = 7
Recall that x = 30 - y
x = 30 - 7
x = 23
Hence there are 23 sharks and 7 octopi in the aquarium
