This is a Pythagorean Problem. Use the formula
c ^2 = a^2 + b^2
Givens
a = 8 - 7 = 1 cm
b = 12 cm
c = ?
solution
c^2 = 1^2 + 12^2
c^2 = 1 + 144
c^2 = 145 Take the square root of both sides
√c^2 = √145
c = 12.04
c = 12.0 to 3 sig digs.
Answer:
12
Step-by-step explanation:
There are 4 different digits to choose from. Since we want 2-digit number, we will see what digits can we put in place of 1st digit and what digit can we place in place of 2nd digit.
Hence, <u><em>how many digits (from 1,5,6 and 8) can be placed in the 1st digit of the number we want?</em></u>
Any one of the four digits (1,5,6, or 8).
Now, <em><u>How many digits (from 1,5,6 and 8) can be placed as the 2nd digit of the number we want?</u></em>
Any one of the THREE digits (since repetition is not allowed, we disregard the initial digit).
Thus the number of two-digit positive integers is 4 * 3 = 12
Answer:
A
Step-by-step explanation:
x+y=34 (add the seperate hours together to get the total amount of hours)
10x+15y=410 (multiply the money made each hour by the hours worked and add them together to get the amount of money joy made)
Step-by-step explanation:
If there are two straight lines the opposite angles equal each other
so 4x+2=150
subtract both sides by 2
4x=148
divide both sides by 4
x=37
Hope that helps :)
