2.) Solve:
-24 - 2m = -4m - 8(m + 8)
Answer:
m = -4
Step-by-step explanation:
First, you should distribute -8 into m + 8 to get -8m - 64. Then, you should combine -4m and -8m together to get -12m as a result. Your equation should now be -24 - 2m = -12m - 64. Add 12 on both sides to get -24 + 10m = -64. Add 24 on both sides to get -40 on the right side. Finally, divide 10 on both sides to get your m value which is -4.
Answer:
-4
Step-by-step explanation:
-24 - 2m = -4m - 8(m + 8) (Remove the parentheses)
-24 - 2m = -4m - 8m - 64 (Collect like terms)
-24 - 2m = -12m - 64 (Move the term)
-2m + 12m = -64 + 24 (Collect like terms, Calculate)
10m = -40 (Divide both sides)
m = -4

What is the radius of a cylinder with a volume of 1650
cubic feet and a height of 10 feet?
Answer:
The radius of cylinder = 7.428 feet
Step-by-step explanation:
Volume of cylinder = 1650 cubic feet
Height = 10 feet
We need to find radius of cylinder
The formula used is: [tex]Volume=\pi r^2h[/tex]
Putting values and finding radius
[tex]Volume=\pi r^2h\\1650=3.14\times r^2 \times 10\\1650=31.4\times r^2\\r^2=\frac{1650}{31.4}\\r^2=52.547\\Now,\:taking\:square\:root\:on\:both\:sides\\\sqrt{r^2}=\sqrt{52.547}\\r= 7.248\:feet[/tex]
So, the radius of cylinder = 7.428 feet
The price of a new car was £12500
It is reduced to £11625
Work out the percentage reduction.
Answer:

What is the equation of a line that has a slope of -3, and passes through the point (-4,8)
Answer:
y = -3x - 4
Step-by-step explanation:
[tex]\frac{8-y}{-4-x} = \frac{-3}{1}[/tex]
[tex]y = 11\\x = -5[/tex]
(-5,111)
y = -3x + b
8 = -3(-4) + b
8 = 12 + b
b = -4
y = -3x - 4

If in a parallelogram, its diagonals bisect each other right angle and are
equal, then it is a
(a)Square (b)Rectangle (c)Rhombus (d)Kite
Answer:
The parallelogram is a "Square" ⇒ (a)
Step-by-step explanation:
In a parallelogram
Every two opposite sides are parallelEvery two opposite sides are equalEvery two opposite angles are equalIts diagonals bisect each otherIf the diagonals of a parallelogram are equal, then it is a rectangleIf the diagonals of a parallelogram are perpendicular to each other, then it is a rhombusIf the diagonals of a parallelogram are equal and perpendicular, then it is a square∵ In a parallelogram, its diagonals bisect each other at right angles
∴ Its diagonals are perpendicular
∵ Its diagonals are equal
→ By using rule 3 above
∴ The parallelogram is a square

the number 1953125 is equal to 5^9
explain how the infomation above informs that 1953125 is not a square number
Step-by-step explanation:
Given
[tex]1953125=5^9[/tex]
For a perfect square, its square root must be an integer
The square root of 1953125 i.e. [tex]\sqrt{1953125}=\sqrt{5^9}[/tex]
or, [tex]\sqrt{5^9}=5^\frac{9}{2}[/tex]
Clearly, [tex]\frac{9}{2}[/tex] is not an integer so, [tex]5^{\frac{9}{2}}[/tex] is also not an integer
Hence, 1953125 is not a square number
