Answer:
Therefore the length of AB is 15 unit.
Step-by-step explanation:
Given:
A ≡ ( -7 , 4 ) ≡ (x₁ , y₁)
B ≡ ( 8 , 4 ) ≡ (x₂ , y₂)
C ≡ ( 8 , -3 )
D ≡ ( -7 , -3 )
To Find:
Length of AB =?
Solution:
Distance Formula between two points is given as
Substituting the values we get
Therefore the length of AB is 15 unit.
(84)5 = 420
(73)9 = 657
420 + 657 = 1077
Answer:
D
Step-by-step explanation:
Hi,
By definition, interest rate is <span>the proportion of a loan that is charged as interest to the borrower, typically expressed as an annual percentage of the loan outstanding.
To find interest rate you need the principle, interest earned, and time.
</span><span>
Solve for Rate (R)
</span><span>Where: r = I / Pt
</span>
I = 837 (dollars)
P = 3100 (dollars)
t = 6 (years)
r = 837 / ( 3100 × 6 ) = 0.045
<span>r = 0.045
</span>
*converting r decimal to a percentage
R = 0.045 * 100 = 4.5%/year*
The interest rate required to accumulate simple interest of $ 837.00 from a principal of $ 3,100.00 <span>over 6 years is 4.5% per year.
</span>
In short, rate: 4.5% / year

Answer:
20 minutes
Step-by-step explanation:
Remember that
we know that
Hector has 3/4 hour to spend his homework
Convert to minutes
so
1) He wants to spend 1/3 of this time on math homework
To find out the time on math homework, multiply 45 minutes by 1/3
2) He wants to spend 10 minutes of his time on reading homework
3) He wants to spend the remaining time on science homework
The time spend on math homework plus the time spend reading homework, plus the time spend on his science homework must be equal to 45 minutes
Let
x ----> the time spend on his science homework
Solve for x
