Step-by-step explanation:
it's a right angle so x + 63 = 90
that means x = 90-63
therefore x = 27
Answers:
After simplifying the following expression, the coefficient of the m^2 term will be <u> 13 </u>
The solution is <u> 13m^2 + 6mn^2 - 5nm^2 </u>
====================================================
Explanation:
Highlight all the terms that have m^2 in them and nothing else (so that means no variables of n or n^2)
You should highlight 3m^2, 16m^2 and -6m^2 as the three terms.
The coefficients 3, 16 and -6 combine to 3+16-6 = 13
Meaning that 3m^2+16m^2-6m^2 = 13m^2
----------------
There are no other like terms that pair up.
The 6mn^2 and -5nm^2 are different because the exponent 2 is over a different letter each time. Put another way: mn^2 is not the same as nm^2
So we cannot combine 6mn^2-5nm^2. We leave it as is.
Overall, the entire expression simplifies to 13m^2 + 6mn^2 - 5nm^2
Hello!
First of all, we can subtract the stretching time. This gives us 20. If we divide by the four laps we get 5 minutes per lap.
Now, one lap is 400 meters (most tracks are), which is equal to 15,748.03 inches. This means it takes her five minutes to walk 15,748.03 inches. This is also equal to 300 seconds, so it takes her 300 minutes per 15,748.03 inches.
But if we round our big inches number to the nearest ten thousandth, we get 16,000, so in a simpler form her pace is 300/16,000. But we need to find in per second. Therefore we will divide by 300 to find how many inches she walks per second. This means she walks about 53.33 inches per second.
I hope this helps!
Answer:
<em>$550,000</em>
Step-by-step explanation:
You need to find 2% of 500,000 first.
2 x 500,000 = 1,000,000
1,000,000 ÷ 100 = 10,000.
It increases value by 10,000 dollars each year
5 x 10,000 = 50,000.
<em>It will be worth 550,000 dollars in 5 years.</em>
I hope thats answer choice D, sorry if I am wrong.
Answer:
Total students = 68
boys = 24
football total = 3
running = 16
therefore probability = 16/68
which is = 4/17
hope it helps
