Answer:
A=119cmsquare
Perimeter =53.8cm
Step-by-step explanation:
Area =1/2*7(10+24)
=1/2*7(34)
=7*17
=119cmsquare
Perimeter is the distance round the shape
9.9+10+9.9+24
=53.8cm
Answer:
22 and 1/2
Explanation: 1/5(n-10)=6- 7/2
1/5(n-10)= 6(2)/2- 7/2
1/5(n-10)= 6(2)-7/2- 7/2
1/5(n-10)= 5/2
Multiply both sides by 5
n-10=25/2
Add 10 to both sides
45/2
Turn into a proper fraction which is 22 and 1/2
Your answer would be "0.02222222222221333".
I did 5/60 showing how many gallons there were per minute.
I then converted US Gallons per minute to US cups per second using a website.
Hope this helps! Have an amazing rest of your day! :)
6b/9=15
6b = 135
135/6= 22.5=b
6(22.5)/9 = 15
135/9=15
15=15
Explanation
I first did inverse operations and multiplied 15 by 9. Now, we can divide is by the coefficient to find b. Then check to see if our answer is correct.
