Answer:
Correct
The solution is Sarah; The pi button on the calculator gives a more accurate representation for pi than 3.14. Using 3.14 as an approximation for pi yields a less accurate result.
Step-by-step explanation:
You need to change 3/4 to the same denominator of each option and none of them are greater.
He should first multiply both sides by 8, to get rid of the denominator.
5/8 m = 25
8(5/8 m) = 8(25)
5m = 200
He should then divide both sides by 5, to get rid of the coefficient
5m/5 = 200/5
m = 40
So m = 40 by these steps
Answer:
224
Step-by-step explanation:
Hello!
To find f(-7) you simply plug the value, -7, into the function.
This will get you:
f(-7) = 4(-7)^2 - 4(-7)
Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!
This will get you:
f(-7) = 4(49) - 4(-7)
f(-7) = 196 - (-28)
f(-7) = 224
Hope this helps!
First we can either add 19 and 11, or we can do this another way.
19 + 11 = 30 To find how much thirty tens are, just add a 0 on the end of 30: 300
The other longer way to do it is: add a 0 to 19: 190, then add a 0 to 11: 110
110 + 190 = 300
There is your answer!
