divide 15 and 27 by 3, 6, 9
Answer:
15: 5, 2.5, 1.6666......
27: 9, 4.5, 3
Step-by-step explanation:
For 15:
So first you divide 15 by 5, which equals 3
Long division:
then by 6. 15/6 can be simplified to 5/2, which can be easier to figure out.
And by nine. 15/9 can be simplified to 5/3 which is harder than 5/2, but you can figure it out by long division. 3 fits once in 5, and there is two left over. Add a decimal after 1 and a zero after the two. 3 fits 6 times into 20 (18), but the cycle continues forever resulting in 1.666666.......
For 27:
27/3 is nine
for 27/6 you can simplify to 9/2, which is like 90/2=45, just move the decimal over one spot to make 4.5
for 27/9, the answer is 3

What sum of money, invested at 9%
interest per year, is needed to provide an
income of $45 per year?
Answer:
$500
Step-by-step explanation:
Intrest = P. A * Intrest Rate * Time
Time = 1 year, Intrest Rate = 9%, P. A. is what we need to find, Intrest is 45
45=x*9/100*1, x=500
Answer:
500
Step-by-step explanation:
I = PRT where I is the interest, P is the amount invested, R is the rate and T is the time
We want 1 year at 9% to get 45 dollars in interest
45 = P ( .09) (1)
45 = .09P
Divide each side by .09
45/ .09 = P
500 =P
10. What is the multiple zero and multiplicity of f(x) = (x - 3)(x - 3)(x + 5)?
Multiple zero is -3; multiplicity is 2
Multiple zero is 5; multiplicity is 1
Multiple zero is -5; multiplicity is 1
Multiple zero is 3; multiplicity is 2
Answer:
D. Multiple zero is 3; multiplicity is 2
Step-by-step explanation:
f(x) = (x-3)(x-3)(x+5)
0 = (x-3)(x-3)(x+5)
x = -5,3,3
notice 3 shows up twice. That would be your answer...So D.
Answer:
Multiple zero is 3; multiplicity is 2
Step-by-step explanation:
f(x) = (x - 3)(x - 3)(x + 5)
Rewriting
f(x) = (x - 3)^2(x + 5)
Setting equal to zero
0 = (x - 3)^2(x + 5)
Using the zero product property
(x-3)^2 = 0 x+5 = 0
x-3 = 0 x= -5
x=3 x-5
Since x-3 was squared, the multiplicity is 2
The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area
Answer:
96
Step-by-step explanation:
The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area
width + 4 = length
width = width
2l + 2w = p
width+width +width +width +4 +4 = 40
4width +8 = 40
4width = 32
width = 8
length x width = area
width = 8
length = 12 (width + 4)
12x 8 = 96

In your own words tell how you can use the number line to add and subtract integers.
Answer:
We can use number lines for adding as well as subtracting integers. For doing this:
1. First mark the first integer on the number line.
2. Now to add a positive integer to this number, move to the right on the number line from this number.
3. In case you have to add a negative integer, move to the left on the number line from this number.
4. Subtracting an integer means adding its opposite and hence, if you have to subtract a positive integer from this number, move to the left on the number line from this number.
5. But if you have to subtract a negative integer from this number, move to the right on the number line from this number.

BRAINLIEST TO BEST ANSWER There are ten numbered bags on the table with ten coins in each bag. The coins in one of the bags are fake. A real coin weighs 10 grams, and a fake coin weighs 9 grams. How do you find the bag that contains the fake coins with just one weighing?
Answer:
There are 10 bags. 9 of the bags have real coins, 1 bag has fakes. A real coin weighs 10 g, a fake coin weighs 9 g.Take 1 coin from the first bag, 2 coins from the 2nd bag, 3 coins from the 3rd bag, 4 coins......., 5 coins............, .........10 coins.......
If there are no fakes at all, the total weight should be: 550 grams.
If the weight is 545 grams, there would be 5 fakes, and so the fake bag would be Bag 5. (because there is a 5 gram difference)

B.5 Additive property of length 7RA
If TU = 4x, UV = 2x + 14, and TV = 7x – 5, what is UV?
T
4x
U
2x + 14
7x - 5
Simplify your answer and write it as a proper fraction, mixed number, or integer
Submit
Answer: UV = 52
Concept:
Additive property of length, or the segment addition postulate, states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
Given information
TU = 4x
UV = 2x + 14
TV = 7x - 5
Given expression deducted from the additive property of length
TV = TU + UV
Substitute values into the expression
7x - 5 = 4x + 2x + 14
Combine like terms
7x - 5 = 6x + 14
Subtract 6x on both sides
7x - 5 - 6x = 6x + 14 - 6x
x - 5 = 14
Add 5 on both sides
x - 5 + 5 = 14 + 5
x = 19
Find UV by substituting the value of x
UV = 2x + 14 = 2 (19) + 14 = [tex]\boxed{52}[/tex]

What should be subtracted from 13/(-56) to get 11/28
Answer:
-5/8
Step-by-step explanation:
13/ -56 -x = 11/28
Add 13/56 to each side
13/ -56 + 13/56 -x = 11/28+ 13/56
-x = 11/28 + 13/56
Get a common denominator
-x = 11/28 *2/2 +13/56
-x = 22/56 + 13/56
-x = 35/56
Divide top and bottom by 7
-x = 5/8
Multiply both side by -1

What is dh/dx if h(x) = cπ, where c is a constant? Please show work. Will mark the best answer as brainliest.
Answer:
[tex]h'(x)=0[/tex]
Step-by-step explanation:
By definition, the derivative of [tex]f(x)[/tex] is given by:
[tex]\displaystyle \frac{dy}{dx}=f'(x)=\lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}[/tex]
Given [tex]h(x)=c\pi[/tex], [tex]h(x+4)[/tex] must also be [tex]c\pi[/tex]. Therefore, we have:
[tex]\displaystyle h'(x)=\lim_{h\rightarrow 0}\frac{c\pi - c\pi }{h},\\h'(x)=\lim_{h\rightarrow 0}\frac{0}{h}=\boxed{0}[/tex]
Note that the derivative of a constant is always zero since for [tex]f(x)=c[/tex], where [tex]c[/tex] is some constant, [tex]f(x)=f(x+h)[/tex] and we obtain [tex]c-c[/tex] in the numerator, yielding a final answer of zero.

Find the area.
This is a triangle DEN. Side NE has a length of 37 meters. Side DN has a length of 36 meters. The altitude from point D measures 30 meters.
A. 1100 m²
B. 555 m²
C. 338 m²
D. 1066 m²
The area of a triangle is the product of its height and base divided by 2. The area of [tex]\triangle DEN[/tex] is [tex]555m^2[/tex]
Given that:
[tex]NE = 37[/tex]
[tex]DN = 36[/tex]
[tex]h = 30[/tex] --- altitude from point D
The altitude from point D will meet with side NE.
So, we have:
[tex]Base = NE = 37[/tex]
[tex]Height = 30[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} \times base \times Height[/tex]
This gives:
[tex]Area = \frac{1}{2} \times 37 \times 30[/tex]
[tex]Area = 555[/tex]
Hence, the area of [tex]\triangle DEN[/tex] is [tex]555m^2[/tex]

Answer:
I HOPE IT WILL HELP YOU.....
Answer:
see explanation
Step-by-step explanation:
Given 2 equal matrices, then corresponding elements are equal , so
4 + p = 10 ( subtract 4 from both sides )
p = 6
5 + 2q = 6 ( subtract 5 from both sides )
2q = 1 ( divide both sides by 2 )
q = 0.5
7r = 7 ( divide both sides by 7 )
r = 1
4s = 16 ( divide both sides by 4 )
s = 4
A solid is formed by rotating the region bounded by y = x − x^2 and y = 0 about the line x = 2 . Use the shell method to find the volume of the solid.
Answer:
The volume of the resulting solid is π/2 cubic units.
Step-by-step explanation:
Please refer to the diagram below.
The shell method is given by:
[tex]\displaystyle V = 2\pi \int _a ^b r(x) h(x)\, dx[/tex]
Where the representative rectangle is parallel to the axis of revolution, r(x) is the distance from the axis of revolution to the center of the rectangle, and h(x) is the height of the rectangle.
From the diagram, we can see that r(x) = (2 - x) and that h(x) is simply y. The limits of integration are from a = 0 to b = 1. Therefore:
[tex]\displaystyle V = 2\pi \int_0^1\underbrace{\left(2-x\right)}_{r(x)}\underbrace{\left(x - x^2\right)}_{h(x)}\, dx[/tex]
Evaluate:
[tex]\displaystyle \begin{aligned} V&= 2\pi \int_0 ^1 \left(2x-2x^2-x^2+x^3\right) \, dx\\ \\ &= 2\pi\int _0^1 x^3 -3x^2 + 2x \, dx \\ \\ &= 2\pi\left(\frac{x^4}{4} - x^3 + x^2 \Bigg|_0^1\right) \\ \\ &= 2\pi \left(\frac{1}{4} - 1 + 1 \right) \\ \\ &= \frac{\pi}{2}\end{aligned}[/tex]
The volume of the resulting solid is π/2 cubic units.
