The sum of two numbers is 32 their difference is 10. Find the numbers.
The two numbers are: 21 and 11
Step-by-step explanation:
Let x and y be the two numbers.
x+y = 32
x-y = 10 Rewrite this as x = y+10 and substitute for x in the first equation.
(y+10) + y = 32 Simplify and solve for y.
2y+10 = 32 Subtract 10 from both sides.
2y = 22 Divide both sides by 2.
y = 11
x = y+10
x = 11+10
x = 21
Answer:
y = 11
Step-by-step explanation:
x + y = 32
10 + y + y = 32
10 + 2y = 32
2y = 22
y = 11

The volume of a cylinder is given by the formula y = rrah, where r is the radius of the cylinder and h is the height.
Which expression represents the volume of this cylinder?
n = 2x + 7
0 0
0 24x3 – 12xx2 - 24 xX+63%
O 28x3 - 5 xX2 – 24 xX+63x
O 28x3 + 7 xx? - 18xx-63
The volume of the cylinder with radius r = x - 3 and height h = 2x + 7 is given by the expression V = π ( 2x³ - 5x² - 24x + 63 )
What is a Cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is
Volume of Cylinder = πr²h
Surface area of cylinder = 2πr ( r + h )
where r is the radius of the cylinder
h is the height of the cylinder
Given data ,
Let the volume of the cylinder be represented as V
Now , the radius of the cylinder r = ( x - 3 ) units
Let the height of the cylinder be h = ( 2x + 7 ) units
And , Volume of Cylinder = πr²h
On simplifying the equation , we get
Volume of Cylinder = π ( x - 3 )² ( 2x + 7 )
Volume of Cylinder = π ( x² - 6x + 9 ) ( 2x + 7 )
On further simplification , we get
Volume of Cylinder = π ( 2x³ - 5x² - 24x + 63 )
Hence , the expression for the cylinder is V = π ( 2x³ - 5x² - 24x + 63 )

Please.... I really need help with this ASAP
Answer:
90km/h
Step-by-step explanation:
The average speed is the total distance travelled/the time taken to do so. Being a distance-time graph, it shows that the car travelled 60km away from the starting point, stayed for a bit and then drove back. This gives a total distance of 120km. It also says that they started at 7:00am and finished at 8:20am which is 1 and 1/3 hours or 1.33 hours (1 hour 20minutes).
120/1.333...=90
Their average speed for the entire journey was 90km/h.

Rewrite the equation y-2=-(x+5) in slope intercept form.
Answer: y-2=-(x+5)= Slope = -2.000/2.000 = -1.000
Step-by-step explanation: y is -3.000 and for x=2.000, the value of y is -5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.000 - (-3.000) = -2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

130% of what number is 20.8
Answer 16
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
The equation would be 130% x N = 20.8
To solve you would have to switch the equation around and to do that you would divide. 130% is the same as 1.30 or 1.3
20.8 ÷ 1.3 = 16
N = 16

Determine the value of x
Answer:
x would be 10
Step-by-step explanation:
angles across from each other are always equal so x would be 10 because 3 times 10 is 30 and then add the other 10 to get 40
Answer:
x = 10
Step-by-step explanation:
Since these angles are vertical angles, we know that 40 = 3x + 10. Subtract 10 from both sides to get 30 = 3x. Divide both sides by 3 to get x = 10.

Identify the number of molecules in the chemical formula for Butane.
5C4H10
2
4
5
or 10
Answer:
the way you have the question on here is weird, but I'm pretty sure the answer is 5
Step-by-step explanation:
molecules are groups of bonded atoms, so one molecule of Butane would be C4H10 by itself, but if you have 5 of those, you have 5 molecules.
however, if you're talking about the number of ATOMS in one molecule of Butane, there would be 14 (4 carbon, 10 hydrogen)
