An hour has 60 minutes in it, so the simplified form would be
2 14/60 (The 2 should be the whole number in front of the fraction)

In order to change it into a decimal, change it into an improper fraction and divide
134/60

Zack has two savings accounts with the total of $9,000. He withdew 10 percent from one and 60 percent from the other to buy his
klio [65]

The remaining balances in the first and second account are $5805 and $1020 respectively.

<em><u>Explanation</u></em>

Suppose, the initial balance in the first account was  x dollar.

As the total amount in two accounts was $9000, so the <u>initial balance in the second account was</u>  (9000-x) dollar

He withdrew 10% from the first and 60% from the second account to buy the ring which cost $2175. So, the equation will be......

0.10x+0.60(9000-x)=2175\\ \\ 0.10x+5400-0.60x=2175\\ \\ -0.50x= 2175-5400= -3225\\ \\ x=\frac{-3225}{-0.50}= 6450

So, <u>the initial balance</u> in the first account was $6450 and in the second account was ($9000 - $6450)= $2550

Thus, the remaining balance in the first account = 90% of $6450 = (0.90*6450)= \$5805

and the remaining balance in the second account = 40% of $2550 = (0.40*2550)=\$1020

Describe how the circumference and the diameter of a circle are related.
Readme [11.4K]
The circumference of a circle is the distance around the outside of the circle. The diameter is the distance across the circle. It must pass through the center or the circle. For any circle, regardless of diameter, there is a consistent ratio between the circle's circumference and the length of its diameter.

const2013 [10]

Answer:

Circle = 7

Pentagon = 8

Square = 12

Square + Square + Square = 36

Step-by-step explanation:

Since you know the circle is 7, the square plus the pentagon must be 20. That means the pentagon in the third equation is 8. This means the square is 12.

So, 12 + 12 + 12 = 36.

Complete the following to analyze the graph shown.
Svetradugi [14.3K]
At zero, the value of the function is zero. It then rises to its maximum value, then falls to zero and then to its minimum value and then back to zero.

So, the graph follows the pattern of Sine Function: <span>(B. zero-max-zero-min-zero) starting at the origin. This suggest the coefficient a of the sine function is positive.

Maximum value of the function as seen from the graph is 5, and the minimum value is -5. So the amplitude of the function is 5 and the vertical translation k = 0 as the graph rises equally above and below x-axis.</span>
