Answer:
9d^2/(2d + 4).
Step-by-step explanation:
18d^2 / (4d + 8)
First factorise the denominator:
= 18d^2 / 4(d + 2)
The GCF of 18 and 4 is 2 so this simplifies to:
9d^2/2(d + 2)
= 9d^2/(2d+ 4).
The perimeter of the worksheet is 28 inches. The worksheet is 6 inches tall. How long is it?
Answer:
The anwser is that it's 8 inches
Step-by-step explanation:
How i figured this out is since it's a woksheet,
I can guess that its a rectangle or quadrtilateral. One side is 6 inches, so the exact opposite side is also the same size, so we would have to double the 6 to 12. We know that the perimeter is 28, we can subtract 28 from 12 so that we can find out how long it is. We get 16 from 28-12 and we need to half the amount to find out how long one side is. let me know if you have any more quesitons because i dont know if i explained it well

Answer:
A=105.12ft sq
Step-by-step explanation:
Area of the rectangle
A=8(10)
A=80
Area of the circle
if d=8 then r=4
A= (1/2) 3.14(4)
A= (1/2) 3.14(16)
A=3.14(8)
A=25.12
Area of the whole thing
A=80+25.12
A=105.12ft sq

Answer: Figure A to Figure B is a scale factor of 0.5
Step-by-step explanation:
It's not too hard to figure out scale factor, since the two shapes are the same aside from their scale. Notice how Figure A is 4 units tall, and that Figure Bis 2 units tall. From one figure to another, use the equation Figure B/Figure A to find the scale factor. Although you won't really need to memorize all this, you can count the amount of units on your fingers and figure it out from there.
please solve for M<PRQ
Answer:
[tex] m\angle PRQ =49\degree [/tex]
Step-by-step explanation:
[tex] m\angle PSQ = 360\degree - (128\degree + 134\degree )[/tex]
[tex] m\angle PSQ = 360\degree - 262\degree [/tex]
[tex] m\angle PSQ = 98\degree [/tex]
Now, by inscribed angle theorem:
[tex] m\angle PRQ = \frac{1}{2} \times m\angle PSQ [/tex]
[tex] m\angle PRQ = \frac{1}{2} \times 98\degree [/tex]
[tex] m\angle PRQ =49\degree [/tex]
find the value of x.
Answer:
x = 4
Step-by-step explanation:
Given a line parallel to a side of the triangle and intersecting the other 2 sides then it divides those sides proportionally, that is
[tex]\frac{10-x}{x}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )
3x = 2(10 - x)
3x = 20 - 2x ( add 2x to both sides )
5x = 20 ( divide both sides by 5 )
x = 4

Find the surface area of the regular pyramid. 14mm and height is 11.
Answer:
504
Step-by-step explanation:
TSA (total surface area) = 1/2(p)(l) + B
p (perimeter) = 4(14) = 56
l (slant length) = 11
B (area of vase) = 14(14) = 196
TSA = 1/2 (56) (11) + 196
= 28(11) + 196
= 308 + 196
= 504

What is the unit rate, in dollars per pound?
Answer:
4 dollars for every pound
Step-by-step explanation:
Mr Chua borrows a sum of money from the bank which charges a compound interest of 4.2% per annum, compounded quarterly. Given that Mr Chua had to pay $96.60 in interest payments at the end of the first year, find their original sum of money borrowed, giving your answer correct to the nearest cent.
Answer:
Original sum of money = $2246.51
Step-by-step explanation:
Interest = $96.60
Interest is compounded 6 times in a year ; n = 6
time = 1 year ; Rate of interest (r) = 4.2%

[tex]4x - 6 + 2x = 3(2x - 2)[/tex][tex]6x - 6 = 6x - 6[/tex]the required solution is
6x - 6 = 6x -6
Answer:
All real numbers
Step-by-step explanation:
-distrubute 3 through parentheses
4x-6+2x=6x-6
-cancel equal terms on both sides
4x+2x=6x
-collect like terms
6x=6x
the statement is true for any value of x because both sides are true

Pls help with this circles problem for math.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
Point A is arbitrarily located. We have drawn the circle on a grid, so have made points A and E on orthogonal axes through point O.
1. Point B can be anywhere on the circle except on line AO.
2. Making circle A have the same radius as circle O puts points C and D 120° apart.
3. In this diagram, OF bisects right angle EOA, so central angle EOF is 45°.

what is the sum of the following equation?
3/10 + 39/100=
Answer:
69/100
Step-by-step explanation:
You need to make the denominators equal, so multiply 10 by 10, which makes 100. Whatever you do to the denominator, do to the numerator.
30/100 + 39/100 = 69/100
Answer:
69/100
Step-by-step explanation:
3/10 + 39/100
In order to find the sum of this equation, you must first identify the least common denominator.
10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120
100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200
The lowest number 10 and 100 have in common is 100.
Second, we must make both fractions have a denominator of 100.
**MULTIPLY THE NUMERATOR AND DENOMINATOR BY THE SAME THINGS!!**
3/10 x 10/10 = 30/100
39/100 x 1/1 = 39/100
Lastly, we add the new fractions.
30/100 + 39/100 = 69/100
69/100 is already in the simplest form.
Therefore, 3/10 + 39/100 = 69/100

Combine the like terms to create an equivalent expression:
-3.2 - 6+ (-1)
Answer:
-3x + (-7)
Step-by-step explanation:
First you want to find the like terms, in this case it is the numbers without a coefficient, (6 and -1). So you are then left with -6+(-1) which equals to -6-1 = -7. Finally, you combine the number with the coefficient (-3x) with the number without it (-7) and you get -3x-7
Answer:
-3x-7
