Step-by-step explanation:
Convert both perecentages to decimal form by dividing each of them by 100 to get 0.60 and 0.65. Next, multiply by 0.60 and 0.65 to get 0.39. Multiply the product by 100 to get the percentage form, 39%. So, the answer is 39%.
D
is certainly wrong. You could extend the length of AD as far as you want and the two triangles (ABD and ACD) would still be congruent.
C
is wrong as well. The triangles might be similar, but they are more. They are congruent.
B
You don't have to prove that. It is given on the way the diagram is marked.
A
A is your answer. The two triangles are congruent by SAS
(3x+2)-(2x-2)
3x+2-2x-2
3x-2x=x
2-2+0
X
Answer:
$330
Step-by-step explanation:
What is mean/average?
It is the "sum of all the numbers" divided by the "number of numbers".
An average of 200 for 6 numbers means:
THus, if we were to add the 6 numbers, we would get "1200". Let the 6th number be x, so we can write:
120 + 110 + 200 + 300 + 140 + x = 1200
870 + x = 1200
x = 1200 - 870
x = 330
To make the average $200, Pedro needs to make $330 on 6th day.
