the length of a rectangle is 3 times its width. the rectangle's width is 4 m. what is area of the rectangle?
Answers
when width is 4 and length is 3 times greater than it so length is 12m now, area=length x breadth =12mx 4m =48m²

What is unit conversion?
It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
2,200 yards ____(1)
1 mile = 1760 yards _____(2)
Now,
From (1) and (2),
1 mile = 1760 yards
Multiply 2,200/1760 on both sides.
2,200/1760 x 1 mile = 2,200/1760 x 1760 yards
1.25 miles = 2,200 yards
Rounding to the nearest tenths.
1.3 miles = 2,200 yards
Thus,
There are 1.3 miles in 2,200 yards.

Answer:
1.25 mi
Step-by-step explanation:
First, we want to convert a yard into feet; recall 1 yard = 3 feet.
Then we want to divide that by the number of feet in a mile 1 mile = 5280feet.
So 2200*3 =6600, then divide by 5280
6600/5280 = 1.25 mi
2200 yard is 1.25 miles

Answer:
Slope = rise/run =3/12 =1/4
Step-by-step explanation:
Slope is defined as the rate of change of y wrt x.
Rate of change of y is sometimes named as rise and rate of change of x is named as run.
Given that Rate of change of y i.e. rise is 3 and rate of change of x i.e. run is 12.
Hence slope = 3/12 =0.25

Answer:
Option B. x = -1, 19
Step-by-step explanation:
The given equation is x² - 18x = 19
We can get the value of x by factorizing the expression or by quadratic formula.
We will try to factorize the equation first. If we find no factors then we will apply quadratic formula to get the value of x.
x² - 18x - 19 = 0
x² - 19x + x - 19 = 0
x(x - 19) + 1(x - 19) = 0
(x - 19)(x + 1) = 0
x = 19, -1 will be the solutions.
So there is no need to apply quadratic formula.
Option B. x = -1, 19 is the answer.
REMEMBER THIS
ok
first, make sure that a is 1
done
now take 1/2 of b and square it
-18/2=-9, (-9)^2=81
add that to both sides
x²-18x+81=19+81
x²-18x+81=99
factor perfect square
(x-9)²=100
square root both sides
don't forget positive and negative root
x-9=10
x-9=-10
ad 9 to both sides
x=19
x=-1
answer is -1; 19

Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
We need a parabola with a vertex at (0,-3)
If we select the equation:
When we put x = 0, we get
And similarly, when we put y = -3, we get
Hence, third option is correct.
