28
How?
Multiples of 4=8,12,16,20,24,28Multiples of 14=28,42We can see that 28 is the lowest common multiple also it is <30
Answer: 28.
Step-by-step explanation: 28 is divisible by 4: 28 / 4 = 7. 28 is divisible by 14: 28 / 14 = 2. And 28 is less than 30
What is the area of the rectangle ABCD? Help
if a+1/a=3
What is the answer? a⁵+1/a⁵
Answer:
123
Step-by-step explanation:
We can square and cube the equation, then multiply the results together.
(a + [tex]\frac{1}{a}[/tex]) = 3 ← square both sides
a² + 2 + [tex]\frac{1}{a^2}[/tex] = 9 ( subtract 2 from both sides )
a² + [tex]\frac{1}{a^2}[/tex] = 7 → (1)
-----------------------
Now cube both sides
a³ + [tex]\frac{1}{a^3}[/tex] + 3(a + [tex]\frac{1}{a}[/tex]) = 27
a³ + [tex]\frac{1}{a^3}[/tex] + 3(3) = 27
a³ + [tex]\frac{1}{a^3}[/tex] + 9 = 27 ( subtract 9 from both sides )
a³ + [tex]\frac{1}{a^3}[/tex] = 18 → (2)
------------------------------
Multiply (1) and (2)
(a² + [tex]\frac{1}{a^2}[/tex] )(a³ + [tex]\frac{1}{a^3}[/tex] ) = 7(18)
[tex]a^{5}[/tex] + ( [tex]\frac{1}{a}[/tex] + a) + [tex]\frac{1}{a^5}[/tex] = 126
[tex]a^{5}[/tex] + 3 + [tex]\frac{1}{a^5}[/tex] = 126 ( subtract 3 from both sides )
[tex]a^{5}[/tex] + [tex]\frac{1}{a^5}[/tex] = 123

The probability of a red candy being selected from a bowl is 0.9, and the probability of a pink frosted animal cookie being taken out of a different bowl is 0.4. What is the probability of getting both a red candy and a pink cookie?
Answer:
0.36
Step-by-step explanation:
To find the probability, just multiply.
probability of red candy * probability of pink cookie
0.9*0.4=0.36

If f(x) = 6/x-1
for what value of x does f(x) = 5 ?
Answer:
11/5
Step-by-step explanation:
f(x) = 6/x-1
f(x) = 5
6/x-1 = 5
=> 6 = 5(x-1)
=> 6 = 5x - 5
=> 11 = 5x
=> 5x = 11
=> x = 11/5

The supplement of an angle is four times the compliment of the angle find the angle
Answer:
72
Step-by-step explanation:
one angle = x
other one, 4x
they're compliment,
so,
x+4x=90
or, 5x=90
or, x=18
so the angle is 4x=4×18=72
Answer:
60°Step-by-step explanation:
Let the angle is x.
Supplement of x:
180 - xComplement of x:
90 - xWe have:
180 - x = 4(90 - x)Solve for x:
180 - x = 360 - 4x4x - x = 360 - 1803x = 180x = 60PLS TELL ME HOW TO FIND THIS ANGLE

ZC and ZD are vertical angles with MZC = –2x + 90 and MZD = x – 30.
What is mZD
Enter your answer in the box.
Answer:
10
Step-by-step explanation:
Vertical angles are equal to each other
-2x + 90 = x - 30
90 + 30 = x + 2x add like terms
120 = 3x divide both sides by 3
40 = x
angle <ZD is x - 30 so the answer is 10

The area of the triangle with a base of 9 inches and height of 13 inches is 58.5in^2
We have given that,9 in,16 in, and 13 in
Drawing not to scale
We have given that the triangle
What is the formula for the area of the triangle?
area of triangle = 1/2 × base × height
therefore,
Use the given value in the formula so we get

Step-by-step explanation:
Each employee in a company is either right-handed or left-handed.
32 of the 54 employees are female.
18 of the 41 right-handed employees are male.
Complete the frequency tree for this information.
right-handed

right-handed
male
left-handed
Total marks: 3
Answer:
32 female - 23 right-handed || 9 left-handed
22 male - 18 right handed || 4 left handed
Step-by-step explanation:
I find it easiest to write all the information out and fill the gaps.
From what we're given, 32 employees are female, that means 22 are male, as 54 - 32 = 22.
We are also given that there are 41 right-handed employees, which means there is 13 left-handed employees by subtraction.
If 18 of the right-handed employees are male, then 23 of them are female, and 4 are left-handed males.
If 23 of the female employees are right-handed, then 9 female employees are left-handed.

What is the probability of picking 1 blue marble and 1 green marble?
(Once a marble is chosen it is NOT put back into the box).
(Write your answer in the form of a decimal, round to 2 places).
Answer:
0.02
Step-by-step explanation:
either picking a green then blue;
5/22 x 1/21= 5/462
or picking a blue then green;
1/22 x 5/21= 5/462
total is 10/462 which is approximately 0.02

Answer:
Hello,
Answer D
Step-by-step explanation:
I suppose that i is the imaginary (i²=-1)
i^4=1
i^99=i^(4*24+3)=i^3
i^3-i^3=0
Answer D
Answer: D) 0
======================================================
Explanation:
Take note of this pattern
i^0 = 1i^1 = ii^2 = -1i^3 = -ii^4 = 1After this point, we repeat the cycle. The cycle is 4 units long. This means we can divide the exponent over 4 and look at the remainder
99/4 = 24 remainder 3
So i^99 = i^3
which means i^99 - i^3 = i^3 - i^3 = 0
