Answer:
Step-by-step explanation:
Look at the 3rd decimal digit (the digit after the hundredths).
if it is the digit is less than 5 then round the number down by taking away the decimal point of the number after the 2nd decimal place;However if it is 5 or more then round the number up by adding one on to the hundredths digit and removing the rest of the decimal part of the number after itFor example,4.749 rounds up to 4.75 because the 3rd decimal digit is a 9.

Aram has been studying the mathematics behind pinball machines. He made the following diagram of one of his
observations. Determine the measure of the missing angle.
Given:
A diagram of Aram's observations.
To find:
The measure of the missing angle.
Solution:
From the given figure it is clear that the three angles [tex]52^\circ,x^\circ,68^\circ[/tex] lie on a single point and right side of a straight line.
So, the sum of angle [tex]52^\circ,x^\circ,68^\circ[/tex] must be [tex]180^\circ[/tex].
[tex]52^\circ+x^\circ+68^\circ=180^\circ[/tex]
[tex]x^\circ+120^\circ=180^\circ[/tex]
[tex]x^\circ=180^\circ-120^\circ[/tex]
[tex]x^\circ=60^\circ[/tex]
Therefore, the measure of the missing angle is [tex]x^\circ=60^\circ[/tex].
The radius of a cylindrical construction pipe is 2 ft. If the pipe is 17 ft long, what is its volume?
Use the value 3.14 for it, and round your answer to the nearest whole number.
Answer:
[tex]volume \: = \: \pi \times r {}^{2} \times length(height) \\ = 3.14 \times 2f \times 17ft \\ = 106.76ft {}^{3} [/tex]
Answer:
V = 106.76ft
Step-by-step explanation:
Cylinder Formulas in terms of r and h
Calculate the volume of a cylinder: V = πr2hCalculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrhCalculate the top and bottom surface area of a cylinder (2 circles): T = B = πr2Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)- 3y + 4xy -2x^2 + 2x + y^2 - 4xy + 2y + 3x^2
Answer:
x² + y² + 2x - y
Step-by-step explanation:
-3y + 4xy - 2x² + 2x + y² - 4xy + 2y + 3x²
3x² - 2x² + y² + 2x - 3y + 2y + 4xy - 4xy
x² + y² + 2x - y
this is so confusing to me

1.) Finding the top volume mean multiplying the height of the top (6 m) , width, and length.
2.) Finding the bottom is the height of the bottom (5 m) , width, and length.
3.) Finding the total is adding both bottom and top!
what is y=-x-4 if x=-2
Answer:
-2
Step-by-step explanation:
The answer is -2
Explanation:
First of all we need to identify the problem.
Y= -X-4
We can tell already from this that the X is going to be negative.
If X=-2
Now we can change the problem to:
Y= -2-4
And can even change it to
-2-4
Well the way I learned it

The length of the side AC will be equal to 5.69 cm
What is quadrilateral?A figure consisting of four sides connected together and forming a total angle of 360 degrees is called a quadrilateral.
Given that:-
ABCD is a kite, so AC I DB and DE= EB.
AD = 4 cm BD = 4 cm and CD = 3 cm.
The side AC will be calculated as:-
Since AC is bisecting the line BD so BE = ED and BE = 2 cm and ED = 2 cm. WE have AD = 4 cm so we will calculate AE first by using the Pythagorean theorem.
AE² = AD² - ED²
AE² = 4² - 2²
AE² = 16 - 4 = 12
AE = √12 = 3.46 cm
Similarly, we will find the value of EC.
EC² = 3 ² - 2²
EC² = 9 - 4 = 5
EC = √5 =2.23
WE know that AC = AE + EC
AC = 3.46 + 2.23
AC = 5.69 cm
Therefore the length of the side AC will be equal to 5.69 cm

32$
50$
30$
Answer:
It would be 30$.
Step-by-step explanation:
Lets break this down.
50% off 100 would be 50. 50 is half of 100, therefore we know that 50% is half off of something.
We can either divide 60 by 2, or split 60 in half. In turn, we receive 30.

A three-dimensional L-shaped figure is made of two rectangular prisms joined at a right angle. A horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. A vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. What is the total volume of the composite figure?
The total volume of the composite figure is 64 in³.
Volume of a rectangular prismThe volume of a rectangular prism, V = lwh where
l = length, w = width and h = heightVolume of horizontal rectangular prismSince horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. So,
l = 8 in, w = 2 in and h = 2 in.So, its volume V' = lwh
= 8 in × 2 in × 2in
= 32in³
Volume of vertical rectangular prismSince the vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. So,
l = 2 in, w = 2 in and h = 8 in.So, its volume V" = lwh
= 2 in × 2in × 8 in
= 32 in³
Volume of composite figureThe volume of the composite figure V"' = V' + V"
= 32 in³ + 32 in³
= 64 in³
So, the total volume of the composite figure is 64 in³.
