Given:
height : 3 feet
base : 19 feet
Area of a triangle = (height * base) ÷ 2
A = (3 ft * 19 ft) ÷ 2
A = 57 ft² ÷ 2
A = 28.5 ft²
The area of the figure is 28.5 ft². Choice A.
Answer:
Divide by 13, you will get 10x - 1
Answer:
The density would be 2.89 g/ml
Step-by-step explanation:
To find this, we first need to find the mass of the rock. we can do this by subtracting the weight of the water and cylinder from the weight after the rock is added.
250g - 120g = 130g
Now we need to find the volume. To get this, we subtract the volume of the water before and after the rock is added.
75ml - 30ml - 45ml
Now we use the density formula and solve
D = m/v
D = 130g/45ml
D = 2.89 g/ml
Hey there!
This is a little confusing. But it’s 10. If there’s 2 sides with the length of 4 and one with 10, then it’s not a closed triangle. With two sides lengths of 10 and one with 4, the triangle is able to be closed.
I hope this helps!
