Answer:
She deposits $350 into the account at the beginning of the year.
Step-by-step explanation:
Let us assume that Keegan deposits $P into her savings account at the beginning of the year.
The account earns 3% simple interest each year and she has $360.50 in her account at the end of the year.
If Keegan did not make any additional deposits or withdrawals during the year.
So, we can write that ![P[1+\frac{3}{100} ]= 360.50](https://tex.z-dn.net/?f=P%5B1%2B%5Cfrac%7B3%7D%7B100%7D%20%5D%3D%20360.50)
⇒ P = $350 (Answer)
Answer
Exterior,18°
Interior,162°
Step-by-step explanation:
To calculate exterior,360°÷no of sides, i.e
360°÷20=18°
Interior is gotten by 180°-exterior angle
180°-18°=162°
Answer: 7 to 4
Step-by-step explanation: There are 16+12=28 total students, and 16 boys. Therefore, the ratio is 28:16, but you must simplify that, you can do this by dividing both values by 4 to get 7:4.
Answer:
y = -1/2x + 2
Step-by-step explanation:
A perpendicular line will have a opposite reciprocal slope.
Since the line's slope is 2, the perpendicular line will have a slope of -1/2
Plug in the slope and given point into y = mx + b, and solve for b
y = mx + b
3 = -1/2(-2) + b
3 = 1 + b
2 = b
Plug in the slope and b into y = mx + b
y = -1/2x + 2
So, the equation is y = -1/2x + 2
