Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h
23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified
24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values
.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.
Answer:
y=5
Step-by-step explanation:
all you have to do is divide 6 on both sides
to get 5 cause negatives cancel
X=7 and x= -2. You can use calculator find the answer
Y= mx+b
7= 2(5)+b
7= 10+b
-3= b
The answer is:
y= 2x-3
Well, since we have not actually done this experiment, we cannot use a experimental probabiltity, so we can say the correct answer is: <span>
</span><span>D. The theoretical probability is 50%.</span>
