Answer:
See below.
Step-by-step explanation:
Cinder cone volcanoes = 13
Shield volcanoes = 18
Stratovolcanoes = 6
Total number of volcanoes:
= 13 + 18 + 6
= 37
________________
P (cinder cone):
13/37 = 0.35
P (shield):
18/37 = 0.49
P (stratovolcano)
6/37 = 0.17

Step-by-step explanation below.
This is proportion so we have to set it up as _/_=_/_
So we would set this up as 18/2=x/10
We multiply 5 on both side.
2x5= 10
18x5= 90
So answer is 90 donuts in 10 boxes.
The arcs in the corners of the triangle mean that all 3 angles are the same.
Because the 3 angles are all the same this means that all 3 sides are also the same.
To solve for X, we can set 2 of the equations to equal each other and solve for x:
6x-3 = 3x +6
Add 3 to each side:
6x = 3x +9
Subtract 3x from each side:
3x = 9
Divide both sides by 3:
x = 9/3
X = 3
And if you replace x with 3 in each of the equations, they all equal 15.
Answer:
area of triangle = 4.5*6/2 = 13.5 sq.yd.
Step-by-step explanation:
The area of a right triangle is half of the product of the sides adjacent to the right angle.
Here the sides adjacent to the right angle are 6 yd and 4.5 yd.
Therefore the
area of triangle = 4.5*6/2 = 13.5 sq.yd.
