The correct answer is $3.1
Explanation : $0.62 x 5 = $3.1
Step-by-step explanation:Step-by-step explanation:
For Sienna to be able to take the square root of both sides while solving a quadratic equation, she must have an expression with square on at least, the side that contains the variable she is trying to determine. Equation of the form:
(x + a) ² = b
'a' and 'b' could be any number, -1, 0, 1/3, -5/6, anything really.
So, she can take square roots of both sides then, like this
√(x + a)² = √b
x + a = ±√b
x = -a ± √b
Square roots always cancel out squares, and the '±' is because a square is satisfies by both + and -, 3² = 9, and (-3)² = 9.
It is the nature of the problem being solved that determines if we take just one or both of these answers.
Answer:Mean is 63. There is no mode. Median is 64.
- Step-by-step explanation: The mean was solved by adding the listed numbers and dividing them by the amount of listed numbers. 86+17+64+63+89+42+80=144 144/7=63 There are no repeated numbers, therefore there is no mode. 64 is the middle number so it is the median.
If you are looking for this equation simplified, your answer will be -2w^2-5wz-14z^2+6w+5z
Answer:
15/60.
Step-by-step explanation:
25/100 is 1/4 so a 4th of 60 would be 15. 1/4 = 1/4
