A rectangle is 64cm long 40cm wide find is area and perimeter
Answers
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.

Which expression is equivalent to 2w? w+w
2w+w
2w-w
w+2
Answers
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
If the simple interest on $1,000 for 8 years is $ 480 then what is the interest rate?
Answers
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%

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.

what are sides 'a' and 'b' called in a right triangle
Answers
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.

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? *
Answers
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.

- Brooklynn Deka
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
