How do you write 24/32 in simplest form?
Answer:
3/4
Step-by-step explanation:
To find 24/32 in its simplest form, you need to find the biggest common factor.
24: 1, 2, 3, 4, 6, 8, 12, 24
32: 1, 2, 4, 8, 16, 32
For these two numbers, it's 8. Divided 24 and 32 by 8.
3/4
Answer:
1 1/23
Step-by-step explanation:
multiply each pair of factors. type the product in the space provided
(6+3i)(6-3i) =______
(4-5i)(4+5i)=_______
(-3+8i)(-3-8i)=______
After multiplication of pair of complex numbers, the results of product are respectively 45, 41, 73
What is complex number?The complex number is a combination of real number and imaginary number. The representation of complex number is like, a + bi.
where a is real part and b is imaginary part, the value of i is √-1.
i × i = -1
i⁴ = 1
Given that, pair of complex numbers
(6 +3i )×( 6 - 3i) = 6×6 -6×3i + 6×3i - (3i × -3i)
= 36 - 18i + 18i + (-3i × 3i)
= 36 + 9
= 45
(4-5i) × (4+5i) = 4×4 + 4×5i - 4×5i - (5i × -5i)
= 16 - 20i + 20i + (-5i × 5i)
= 16+25
= 41
(-3+8i) × (-3-8i) = -3×-3 + (-3× -8i) - 3×8i + (8i × -8i)
= 9 +24i-24i +64
= 73
Hence, The result of products are 45, 41, 73

Step-by-step explanation:
A rental car company charges $38.38 per day to rent a car and $0.14 for every mile driven. Camden wants to rent a car, knowing that: He plans to drive 350 miles. He has at most $270 to spend. Which inequality can be used to determine xx, the maximum number of days Camden can afford to rent for while staying within his budget?
Answer:
5.75 days
Step-by-step explanation:
Given data
let the number of days be x and the number and the number of miles be y
so that the cost of the rental will be
c= 38.38x+ 0.14y---------1
we are told that the amount at hand is $270
hence
270=38.38x+ 0.14*(350)
solve for x
270= 38.38x+49
270-49= 38.38x
221= 38.38x
divide both sides by 38.38
x= 221/38.38
x= 5.75 days
Hence the number of days is 5.75 days
In a right triangle, the shortest leg is 15 centimeters, and one angle equals 30 degrees, what is the length of the
hypotenuse?
Answer:
30
Step-by-step explanation:
This is a 30 60 90 triangle. Since it tells us it a right triangle (which means it has a 90 degree angle). Also it tells us that there is a 30 degree. Using the triangle interior theorem, the third angle is a 60 degree
angle
The longest side or hypotenuse is twice the length of the shortest side. So the hypotunes is 30.
The perimeter of a triangle is 122 centimeters. If two sides are equally long and the third side is 8 centimeters longer than the others, find the lengths of the three sides.
Answer:
2 sides are 38cm long
The third is 46cm long
Step-by-step explanation:
We can use the following equation to solve
[tex]122 =x + x + (x + 8)[/tex]
Reduce
[tex]122 = 3x + 8[/tex]
114÷3 = x
x = 38
We then add 38 and 8 because the 3rd side is 8cm longer

How many of these pitchers can a cylinder with height 9 inches and 2r fill? Explain how you know.
Answer:
4 pitches
Step-by-step explanation:
if a cylinder with height 9 inches and radius r is filled with water, it can fill a certain pitcher. how many of these pitchers can a cylinder with height 9 inches and radius 2r fill? explain how you know.
Solution:
The volume of a cylinder is given by:
V = πr²h;
where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.
A cylinder with height 9 inches and radius r can fill a certain pitcher. Therefore the volume of the cylinder is:
V = πr²h = πr²(9) = 9πr²
V = volume of pitcher = volume of cylinder with radius r = 9πr²
For a cylinder with height 9 inches and radius 2r its volume is:
V2 = πr²h = π(2r)²(9) = 36πr²
Therefore, the number of pitchers a cylinder with height 9 inches and radius 2r can fill is:
number of pitches = 36πr² / 9πr² = 4
Therefore a cylinder with height 9 inches and radius 2r can fill 4 pitches.

Given:
First term of a geometric series = a
Common ratio of the geometric series = [tex]\sqrt{3}[/tex]
To prove:
[tex]S_{10}=121a(\sqrt{3}+1)[/tex]
Solution:
The sum of first n terms of geometric series is
[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]
Where, a is the first term and r is the common ratio.
Putting n=10 and [tex]r=\sqrt{3}[/tex] in the above formula, to get the sum of 10 terms.
[tex]S_{10}=\dfrac{a((\sqrt{3})^{10}-1)}{\sqrt{3}-1}[/tex]
[tex]S_{10}=\dfrac{a(243-1)}{\sqrt{3}-1}[/tex]
[tex]S_{10}=\dfrac{242a}{\sqrt{3}-1}[/tex]
Rationalizing the denominator, we get
[tex]S_{10}=\dfrac{242a}{\sqrt{3}-1}\times \dfrac{\sqrt{3}+1}{\sqrt{3}+1}[/tex]
[tex]S_{10}=\dfrac{242a(\sqrt{3}+1)}{(\sqrt{3})^2-1^2}[/tex]
[tex]S_{10}=\dfrac{242a(\sqrt{3}+1)}{3-1}[/tex]
[tex]S_{10}=\dfrac{242a(\sqrt{3}+1)}{2}[/tex]
[tex]S_{10}=121a(\sqrt{3}+1)[/tex]
Hence proved.

its a right triangle 20ft and 24ft?
Answer:
a triangle, I'm guessing 20ft and 24 ft on the outsides,
would be:
Equation to get the area of a triangle: (A*B)/2
(20*24)/2=Area
20*24= 480
480/2= 240
area= 240
Answer: 240 ft²
Step-by-step explanation:
1. Multiply the base and the height.
2. Divide the product you get by 2.
=> 20 * 24 = 480
=> 480 / 2 = 240

Brooke uses 8.6 pints of blue paint and white paint to paint her bedroom walls. 3/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
3 11/25 pints of white paint
Step-by-step explanation:
8 6/10 is the same as 43/5
if 3/5 of the total pints are blue then 2/5 are white
so multiply 43/5 x 2/5 to get 86/25 which equals 3 11/25
