Answer:
the last option
Step-by-step explanation:
Answer:
- 1) 18 quarters and 30 nickels
- 2) 8 quarters and 12 nickels
Step-by-step explanation:
1) Let quarters be x and nickels be y.
<u>Equations based on given, 48 coins, total of $6 = 600c:</u>
<u>Substitute y in the second equation, y = 48 - x</u>
- 25x + 5(48 - x) = 600
- 25x + 240 - 5x = 600
- 20x = 360
- x = 18
<u>Then value of y is:</u>
2) <u>Similarly to problem 1.</u>
<u>Substitution: y= 20 - x</u>
- 25x + 5(20 - x) = 260
- 25x + 100 - 5x = 260
- 20x = 160
- x = 8
<u>Then finding y:</u>
okay, i have to be honest, this equation is a little tricky because the use of "h" is kind of weird, using it twice to show...what exactly i am not too sure.
the answer:
The variable "t" is the amount of taxes she has to pay for repairing her cracked phone. "t" is shown as an extra amount of money to pay, and since it does not state that taxes were dependent on the amount of time it took to repair the phone, it must have been a fixed price. The amount of money it takes to repair the phone (tax not included) is shown to be dependent on time, though.
Answer:
The volume of ball is <u>33.5 inches³</u>.
Step-by-step explanation:
Given:
Jackie bought a game that contained a ball of 10 jacks. The ball had a radius of 2 inches.
Now, to find the volume of the ball.
As, the ball is in spherical in shape.
Radius(r) of ball = 2 inches.
Now, to get the volume we put formula of sphere:
<em>Taking the value of π = 3.14.</em>
<u><em>So, the volume of ball rounding to nearest tenth = 33.5 inches³. </em></u>
Therefore, the volume of ball is 33.5 inches³.
I think the correct answer would be that they are all 90 degrees. The transversal line cuts the parallel lines into four segments perpendicularly so the angles should be 90 degrees. Hope this helps. Have a nice day. Feel free to ask more questions.
