Answer:
Step-by-step explanation:
Given a triangle has points:
(-5,1),(2,1), (2,-1)
Let us label the points:
A(2,1),
B(-5,1) and
C(2,-1)
To find:
Distance between (−5, 1) and (2, −1) i.e. BC.
Horizontal leg AB and
Vertical leg, AC.
Solution:
Please refer to the attached diagram for the labeling of the points on xy coordinate plane.
We can simply use Distance formula here, to find the distance between two coordinates.
Distance formula :
For BC:
Horizontal leg, AC:
Vertical Leg, AB:
Answer:
a. 30%
b. $893.59
c.
Step-by-step explanation:
a. Given that the carpet costs $427.35, the labor costs $212.52 and other flooring supplies costs $75.
#To get the percent of the flooring bill that will go towards the cost of labor:
Hence, labor costs 30% of the total flooring costs.
b.The total flooring costs is :
Given that she spends 25% more on furniture than on flooring, we multiply the flooring cost by 125% to get the furniture costs:
Hence, she spends $893.59 on furniture.
c.To get what percentage of furniture cost was the night stand.
-Given the total furniture cost is $893.59:
Let x be the cost of the dresser and y the cost of the nightstand;
The percentage is then calculated as:
Hnece the percentage cost of the night stand is
Answer:
$4080
Step-by-step explanation:
We have the amount she will pay back, but first, we need to find the Interest accrued.
Simple Interest is given as:
where P = principal
R = rate
T = time taken (in years)
Therefore, the interest on $3,000 at 9% simple interest for 4 years is:
I = $1080
Therefore, the amount she will pay back is:
$3000 + $1080 = $4080
