Answer:
$3456
Step-by-step explanation:
We are given;
- Money deposited (principle) as $2,700
- Rate of interest is 3.5%
- Time is 8 years
We are required to determine the amount that will remain after 8 years
- We first need to determine the interest earned after eight years using the simple interest formula.
Simple interest = (Principle × rate × interest periods) ÷ 100
Therefore;
Interest = ($2,700 × 3.5% × 8 yrs)÷ 100
= $756
Then determine the amount after 8 years
Amount = Principle + Interest
Therefore;
Amount = $2700 + $756
= $3,456
Therefore, the money in the account after 8 years is $3456
Given:
The graph of two lines.
To find:
The slope of each line and check whether they are same or different.
Solution:
If a line passes through two points, then the slope of a line is:

From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:



The slope of first line is 10.
From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:



The slope of second line is 10.

Therefore, the slopes of both lines are same, i.e. 10.

Answer:
A. 68 units2
Step-by-step explanation:
First of all to solve this problem we have to know the formula to calculate the surface area of the cone
A = area
r = radius = 4
L = 13
π = pi
A = π*r² + π*L*r
we replace with the known values
A = π * (4u)² + π * 13u * 4u
A = 16π u² + 52π u²
A = 68π u²
The surface area of the cone is 68π u²
