Answer:
LA = 120 sq cm
SA = 132 sq. cm.
Step-by-step explanation:
LA = ph where p = perimeter of the base and h = the height of prism.
Your base is a triangle. The third side = 
= 
Now, the perimeter of the triangle is 3 + 4 + 5 = 12
So, LA = 12(10) = 120 sq cm
The area of the base is the area of a triangle. A = bh/2 = 4(3)/2 = 6
SA = 2B + LA where B is the area of the base
SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.
Hello,
1) k = (-5) * (-5) = 25
3) x = 12 * 0 = 0
5) y = (-4) * (-12) = 48
7) z = 0 * 9 / 1 = 0
9) x= 18 / -3 = -6
11) p = -8 / 8 = -1
13) h = 42 / 14 = 3
15) m = -42 / 6 = -7
17) x = -9 * -11 = 99
19) v = -17 / -17 = 1
21) h = 3,136 / 56 = 0,056
23) x = 4,200 / 30 = 0,14
25) m = 21 * -3 = -63
Bye :)

Find the middle number
905,910,928,964,971,978,984,988,994,994
971 and 978 are the middle numbers
Find average of the numbers 971 and 978
Median = 974.5
Answer:
A
Step-by-step explanation:
since it is <= we know that it is including the possibility of being equal so it is not a dotted line leaving only A and B as options. since its is <= it must be on the as the x increases the y must decrease. so the answer is A.
Answer:
315 people
Step-by-step explanation:
Using the given ratio, we can figure out the number of children on the train by doing cross multiplication.
Let x = # of children on train.
7/2 = 245/x
7x = 490
x = 70 children
The total number of people = 70 + 245 = 315 people total
