Answer:
12x+4
Step-by-step explanation:
For the perimeter, we have to add up all sides of the triangle.
(3x-4) + (4x+5) + (5x+3)
3x-4+4x+5+5x+3
(3x+4x+5x) + (-4+5+3)
12x+4
Hello! For this question, we are looking for the percent of change. The formula for percent of change is change/original = x/100, where change is tge difference between two numbers, and the original is the previous number. 136,500 - 130,000 is 6,500. The original number is 130,000. It would be set up like this:
6,500/130,000 = x/100
Let's cross multiply the values. 6,500 * 100 is 650,000. 130,000 * x is 130,000x. That makes 650,000 = 130,000x. Now, divide each side by 130,000 to isolate the x. 130,000x/130,000 cancels out. 650,000/130,000 is 5. There. x = 5% increase. The answer is A: 5%.

<em>The theoretical probability to draw a black marble is </em><u><em>0.23</em></u><em>. </em>
Step-by-step explanation:
First add up the total amount of marbles in the bag.
14 gray marbles + 7 black marbles + 10 white marbles = 31 total marbles.
Since we need the odds of a black marble being drawn, divide 7 (the amount of black marbles) by 31 (the amount of total marbles).
7/31 ---> 0.22580645161 <u><em>(it is easiest to use a calculator on this step)</em></u><em> </em>
Lastly, round the decimal to the nearest hundredth.
0.22580645161 ---> <em>0.23</em>
<em>0.23</em> would be the odds of drawing a black marble.

Answer:
The cow with 4 legs is going 50 miles per hour, while the cow with two legs is going 40 miles per hour.
Step-by-step explanation:
Take the 500 miles apart from your question and divide it by 10 (the hours) after that you get your total: 50 for the 4 legged cow. Minus 10 to get the two legged cow.
