I'll tell you how to find the answers and just use the give angle measure to solve.
9) angle 11 = angle 14
10) angle 9 + angle 15 = 180
11) angle 10 = angle 3
12) angle 7 = angle 14
Answer:
I think you were right, that it was A.
Step One
========
Start with how much was transferred.
r = 4.4 megabytes / second
t = 32 seconds
amount transferred = ????
Formula: amount = r*t
amount = 4.4 * 32 = 140.8 megabytes were transferred.
Step Two
=======
Find the number of megabytes on the drive before the transfer took place.
The amount transferred = 140 megabytes.
The drive recorded when he was done there was 384 megabytes
The amount on the drive was 384 - 140 = 243.2 megabytes to begin with.
Step 3
=====
Find the number of megabytes left before the transfer.
1000 - 243.2 = 756.8 megabytes were left before he began his 32 second transfer.
Step 4
=====
Find the amount of time it would take to fill the drive.
He needs to transfer 756.8
The rate of transfer = 4.4 megabytes / second
t = ????
Formula: Amount transferred = r * t; t= amount / r
t = 756.8 / 4.4
t = 172 seconds.
Interesting question. Thanks for posting. It is a unique application of the more familiar formula
d = v * t
Answer:
Lev is incorrect because (9, 4) is not a solution to the equation.
Step-by-step explanation:
We are given the equation: 3y - 2x = 19
When we are to check if an ordered pair is a solution to an equation, we substitute the pair in the equation and compare the RHS and LHS.
If they come to be equal then we can say that the given pair is indeed a solution to the equation.
So, here, RHS = 19
LHS = 3(4) - 2(9) = 12 - 18
= -6
19
i.e., LHS ≠ RHS
So, we can say that (x, y) = (9, 4) is not a solution to the given equation.
