Answer:
I'm assuming we're solving for the hypotenuse, which is 21.5
Step-by-step explanation:
If a^2+b^2=c^2
Then 19^2+10^2 =461
This is c^2 so we must find the square root of 461
the square root of 461 is 21.47, or 21.5 rounded to the nearest tenth
256.
EXPLANATION:
When you are using exponents, you are basically just doing repeated multiplication.
Whatever the exponent (smaller number is) is how many times you multiply the base number by itself.
So 4 ^4 is 4 x 4 x 4 x 4. (4 fours.)
So 4 x 4 x 4 x 4 is 256.
HAVE A GUD DAY
Let's create expressions and equations to model this situation. Let Anthony's age be a.
"Jim is 3 times as old as his cousin, Anthony." Jim's age is 3a.
"The difference in their age is 18." 3a - a = 18
How old is Jim?
Let's solve the above equation for a to first find Anthony's age.
3a - a = 18
2a = 18
a = 9
Remember, Jim's age is represented by the expression 3a. Substitute Anthony's age, 9, into the expression to find Jim's age.
3a
3(9)
27
Answer:
Jim is 27 years old.
Answer:
sorry cant :(
Step-by-step explanation:
write out the equation:
8y=3+7y (I'm assuming y is the amount of comic books)
8=3+7
8=10
Obviously the equation isn't equal. The nonfiction is greater. By the way, I took out the y because I assumed that y was the amount of books and there was no need to write out 8 times one. On a test, make sure you specify this of the teacher may take off points, if she is using Common Core.
