Answer:
62.8
In a triangle the sum of interior angles is always 180 degree. So by appropriate equation we get the result as
angle C = 90 -27.2=62.8
Answer:
Step-by-step explanation:
x= money earned per hour working as a cashier.
y=money earned per hour working delivering newspapers.
We propose the following system of equations:
5x + 4y =77
6x + 3y=78
We solve the system by reduction method:
-6*(5x+4y=77) ⇒ -30x-24y=-462
5*(6x+3y=78)⇒ 30x+15y=390
---------------------------
-9y=-72 ⇒ y=-72 /-9=8
Now, we get the value of "x" replacing the value of "y" by "8" in any part of the equation above.
5x + 4(8)=77
5x+32=77
5x=77-32
5x=45
x=45/5=9
therefore;
money earned per hour working as a cashier= $9/ hour
money earned per hour working delivering newspapers=$8/hour
Answer:
B. 1/3 or 33.3%
Step-by-step explanation:
<em>H-</em> 1 ,2 ,3, 4, 5, 6
<em>T-</em> 1, 2, 3, 4, 5, 6
Multiples of <em>3:</em> 3, 6, 9, 12, etc..
<em>2/6 simplified is 1/3 </em>
So, the probability that the penny will land on heads and the number cube will land on a multiple of 3, is 1/3 or 33.3%
