the answer would be (1, 7). because slope=change in y/change in x
Answer:
3rd one I believe
Step-by-step explanation:
Answer: 5.5%
Step-by-step explanation:
Since the money invested has grown to $8300 and the principal was $600, this means the interest is:
= $8300 - $6500
= $1800
Simple interest = (Principal × Rate × Time)/100
1800 = (6500 × Rate × 5)/100
Cross multiply
1800 × 100 = 32500 × Rate
Rate = 180000/32500
Rate = 5.5%
Answer:
AB = DC = 12
AD = BC = 10
Step-by-step explanation:
For ABCD to be a parallelogram, opposite side pairs must be congruent. That will be the case when ...
AB = DC
x+4 = 12 . . . . substitute expressions for length
x = 8 . . . . . . . subtract 4
Then the lengths of AD and BC must be ...
BC = AD = x+2 = 8+2 = 10
___
The figure will be a parallelogram when x=8 and sides have lengths ...
AB = DC = 12
AD = BC = 10
_____
<em>Comment on the problem</em>
Of course, if x ≠ 8, or BC ≠ AD, the figure will not be a parallelogram. You are asked to show the figure IS a parallelogram, but all you can really show is that the figure CAN BE a parallelogram. In order to do anything useful with the given expressions for side lengths, <em>you must assume the figure is a parallelogram</em>.
To solve this problem you must apply the proccedure shown below:
1. You must apply the formula for calculate the surface area of a cone, which is:
Where is the radius () and is the slant height () and
2. You need to substitute these values into the formula:
Therefore, the answer is the last option:
