Answer:
8%
Step-by-step explanation:
To find the percent change, we first have to find the amount changed, which is (46000-42500) = 3500. Then, we find what percentage that is of the original amount. Remember that when calculating percentage change, it's important to calculate change with respect to the initial value.
To find the percentage, we can divide 3500 by 42500, and multiply that by 100, resulting in 8 being our nearest whole percent
Answer:
21.5cm
Step-by-step explanation:
41,572=4/3*pi*r^3
Work backwards to solve for r
I know this but I don’t have a paper with me !! Omg
So to start off with this problem, let us call the amount invested in Plan A and B as a and b respectively.
So equation 1: a + b = 250,000
Next, we need to get an equation which is equal to 10,000. So the interest rate in plan a + interest rate in plan b would be equal to 10,000. Rewriting this sentence will give us:
Equation 2: .028a + 0.078b = 10,000
Rewrite the first equation into a = 250,000 - b, and then plug the value into equation 2.
.028(250,000 - b) + 0.078b = 10,000
7,000 - 0.028b + 0.078b = 10,000
-0.028b + 0.078b = 10,000 - 7,000
0.05b = 3,000
b = $60000 amount invested at 2.8% while
250,000 - 60,000 = $190,000 is the amount invested at 7.8%
The mountain climber has travelled 75 feet below sea level while descending down a cliff.
Given:
- A mountain climber at sea level starts descending down a cliff.
- Her location can be represented by -75 ft.
To find:
The distance travelled by a mountain climber.
Solution
- Distance ascending above sea level is taken in a positive direction.
- Distance descending down sea level is taken in a negative direction.
- This negative and positive only represents the direction
The location of mountain climber after descending from cliff = -75 ft
The distance covered by the mountain climber = 75 ft
The mountain climber has travelled 75 feet below sea level while descending down a cliff.
