Answer: Here we have a real life multiplication situation for which an estimate make sense:-
Miley has 212 fiction books. Sharon has 3 times fiction books has many as Miley has, how many fiction books Sharon has
Solution :- Number of fiction books Miley has = 212
Number of fiction books Sharon has= 3 times 212
We know that 212 is near to 200 , so round off 212 to 200 (to the nearest hundred)
Thus the product becomes 
Therefore, the estimated number of fiction books Sharon has=600
Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
Answer) -5/2 quarts per hour
Work) There are 60 minutes in an hour and the faucet is losing water every 15 minutes so divide 60/15 and you get 4, next you take the 5/8 and times it by the 4 and you get -5/2
Let the volume of the cylinder be V cubic meters, the diameter be d meters and the height be h meters.
Now we can write the formula for the volume as follows:
Rearranging the formula, the height becomes:
Well there are multiple different ways to write the equation of a line. The easiest way to do so in this situation would be to use point-slope form: (y-y_1)=m(x-x_1)
y_1 is the y coordinate of any point on the line, x_1 is the x-coordinate of the same point, and m is the slope. In this case it would look like (y-7)=3(x-5).
However, you might be required to answer in slope-intercept form. The equation of the line would then look like y=mx+b, where m is the slope, and b is the y-intercept. To solve for b we need to plug in the point (5,7) into the equation:
y=3x+b
(7)=3(5)+b
7=15+b
b=-8
Now plug b back into the initial equation and then you have your final, fully formed equation:
y=3x-8
