Answer:

z= 117°

y = 34

Hope it helps!

Step-by-step explanation:

(5y - 53) + 63 =180°

5y + 10 =180

5y = 170

y= 34

z and y are congruent (vertical angles)

5 (34) - 53 = z

170 - 53 = z

z = 117

You can use the rules of parallel angles for these so the angles within the c shape add up to 180, this means that z=117 degrees (180-63=117) now you can workout what y is as opposite angles on a point are equal to each other therefore (5y-53) will equal 117
So now you can use this and rearrange to find y
So 5y-53=117
5y=117+53 as the sign changes
5y=170
y=170/5
y=34

Step-by-step explanation:

$19.50

Estimate 62% of 196.<br> A. 80<br> B. 100<br> C. 120<br> O D. 140<br> HURRY PLEASE
Mrac [35]

Answer:

The answer is C: 120

Step-by-step explanation:

Ok so to solve this, you need to know that when "of" is in an equation, it always means multiply.

So 62% of 196 = 62% * 196.

62%  * 196 = 121.52

Then you need to round 121.52 to the nearest option, which is Option C: 120.

Good luck on your assignment (or whatever this is)!! Have a nice day!!

Determine if the following event is mutually exclusive:
sp2606 [1]

Answer:

Ask yourself: "Can I roll a prime number and an odd number at the same time?"

Since the answer is "yes it is possible" (eg: rolling a 3), this means the two events are not mutually exclusive. Mutually exclusive events have nothing in common.

In terms of a venn diagram, mutually exclusive events have no overlapping shared region.Step-by-step explanation:

If a bank has total deposits of $7,200 and reserves of $1,600: instructions: round to the nearest whole number. (a) what is its
Serjik [45]
A.) The current reserve ratio is given by the fraction of the bank's total deposits held in reserves.
Given that the bank's total deposits is $7,200 and the reserves is $1,600, the current reserve ratio is given by:

\frac{1,600}{7,200} \times100\%=22\%.


b.) The loan portfolio is given by (total deposit - reserves) / total deposits

Thus, the loan portfolio of the given bank is given by:

\frac{7,200-1,600}{7,200} \times100\%= \frac{5,600}{7,200} \times100\% \\  \\ =78\%
