If the simple interest on $1,000 for 8 years is $ 480 then what is the interest rate?
Answer:
6%
Step-by-step explanation:
Given data
Principal = $1,000
Time= 8 years
Simple interest= $480
The expression for the simple interest is
Simple interest= PRT/100
Substitute
480= 1000*R*8/100
Cross multiply
480= 8000R/100
480*100= 8000R
48000= 8000R
Divide both sides by 8000
R= 48000/8000
R=6%
A rectangle is 64cm long 40cm wide find is area and perimeter
Answer:
Area= 2560 Perimeter= 208
Step-by-step explanation:
Answer:
64 x 40 = 2,560 <------- your area because multiply the two given lengths.
64 + 64 + 40 + 40 = 208 <---------- your perimeter since opposite sides are parallel which means 2 sides are different. So two of both of the different lengths will be your perimeter.

Answer:
y = 3x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, - 1) and (x₂, y₂ ) = (5, 5)
m = [tex]\frac{5+1}{5-3}[/tex] = [tex]\frac{6}{2}[/tex] = 3 , then
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 5 ) , then
5 = 15 + c ⇒ c = 5 - 15 = - 10
y = 3x - 10 ← equation of line

what are sides 'a' and 'b' called in a right triangle
Answer:
The relation between the sides and angles of a right triangle is the basis for trigonometry.
Step-by-step explanation:
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).
Answer:
The legs
Step-by-step explanation:
In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

Which expression is equivalent to 2w? w+w
2w+w
2w-w
w+2
Answer:
It is equivalent to w+w
Step-by-step explanation:
w+w= 2w
Answer:
A w+w
Step-by-step explanation:
because 2w means 2 * w ( 2 times w)
when you multiply 2 time any number, you add that number twice,
exp... 4 times 2 = 4 + 4
therefore 2w is also w+ w
Need help on a statistics question
Given:
The equation of the line of best fit is :
[tex]y=4.722392638x+50.99539877[/tex]
To find:
The x-intercept and check whether it make sense in this context.
Solution:
We have,
[tex]y=4.722392638x+50.99539877[/tex]
Substitute [tex]y=0[/tex] to find the x-intercept of the given best fit line.
[tex]0=4.722392638x+50.99539877[/tex]
[tex]-50.99539877=4.722392638x[/tex]
[tex]-\dfrac{50.99539877}{4.722392638}=x[/tex]
[tex]-10.7986359202=x[/tex]
So, the x-intercept is at point (-10.7986359202,0). It means the score on final examination is 0 if -10.7986359202 hours spent on studying.
But is does not make sense because the number of hours cannot be negative.

Mark and his three friends ate out at Applebee’s. Their bill totaled $52. If they left the server a 20% tip, how much would each person pay if they split the bill evenly? *
Answer:
$15.71 each
Step-by-step explanation:
I just followed the answer sheet
Answer:
$13.05
Step-by-step explanation:
Given: Mark and his 3 friends = 4 Total cost = $52, percent off: 20%
To find: How much each person would pay if they split the bill evenly.
Solution:
Firstly, since they left the server a 20% tip, multiply 20% by the total cost. Convert it to a fraction. Note: you're adding 20% to the total cost.
[tex]\frac{20}{100}[/tex] + [tex]\frac{52}{1}[/tex]
= [tex]_{52.2}[/tex]
Now, that is done, let's divide the newly found cost by the four friends.
[tex]\sqrt[4]{52.2}[/tex]
= [tex]{13.05}[/tex]
So, they would pay $13.05 evenly.
