Answer:
98 ft²
Step-by-step explanation:
There are a couple of ways you can think about this one. Perhaps easiest is to treat it as a square with a triangle cut out of it. The cutout triangle has a base (across the top) of 14 ft and a height of 14 ft, so its area is ...
A = (1/2)(14 ft)(14 ft) = 98 ft²
Of course the area of the square from which it is cut is ...
A = (14 ft)² = 196 ft²
So, the net area of the two triangles shown is ...
A = (196 ft²) - (98 ft²) = 98 ft²
_____
Another way to work this problem is to attack it directly. Let the base of the left triangle be x. Then the base of the right triangle is 14-x, and their total area is ...
A = A1 + A2 = (1/2)(x ft)(14 ft) + (1/2)((14-x) ft)(14 ft)
We can factor out 7 ft to get ...
A = (7 ft)(x ft + (14 -x) ft)
A = (7 ft)(14 ft) = 98 ft²
Answer:
The first step should be adding 14 to both sides of the equation.
Step-by-step explanation:
14 must be added on both sides of the equation to get 13y by itself. The ultimate goal is to get y by itself if we are solving for y.
Once 14 is added on both sides, you'll get:
13y = 56.
Then 13 would be divided from both sides.
y = 4.3
Answer:
28 small
9 large
Step-by-step explanation:
4200 ÷ 150 = 28 small
4200 ÷ 450 =9 large
Well there is a total of 20 different outcomes and you can only get a sum of 7 four times and 11 once so in total 5 times out of 20 so that is 5 to the twentieth place beyond the decimal but you can round that up to 0.5%.
Answer:
Perimiter= 27
Step-by-step explanation:
It equals that, because in order to find the perimeter of something, you just add all of the sides together. I don't know how to do the area, but I'm sure you'll be able to find how on google. I hope this helped in some way
