Answer:
False, True, True, False
Step-by-step explanation:
I'm pretty sure all your answers are right except the second one. I'm no genus or anything like that tho so I'm not sure. Plus I'm not good at graphs. Well depends how it is.
There are 51 students in total
3:5, 6:10, 9:15, 12:20, 15:25, 18:30, 21:35
21+35= 51
answer: 5h + 2g = 23
to solve problems like this, pull apart the equation.
the sum of five times h and twice g is equal to 23
so, we know we're going to be adding two terms, what are they?
five times h and twice g
so, 5h + 2g.
what does it equal?
the sum of five times h and twice g is equal to 23
this means 5h + 2g = 23

Answer:
20 ft
Step-by-step explanation:
The two triangles in this problem are proportional to each other: so, the ratio between their height and the length of their base is equal for the two triangles.
Therefore, we can apply the rule of three, and we can write:

where:
H = 25 ft is the height of the large triangle
B = 10 ft is the length of the base of the large triangle
h is the height of the small triangle
B = 8 ft is the length of the base of the small triangle
And solving for h, we find:
