What percent of 18 is 24?
Answer:
133.33%
Step-by-step explanation:
you can find this by doing 24/18x100, which is equal to 133.33
Answer:
133%
Step-by-step explanation:
We're going to divide [tex]\frac{24}{18}[/tex].
That equals about 1.33 repeating.
Next, we're multiplying that decimal by 100.
That gets us 133.
What is m∠P? There is a five sided polygon PQRST in which the measure of angle PQR is 132 degrees, the measure of angle QRS is (4x-10) degrees, the measure of angle RST is (5x-11) degrees, the measure of angle STP is 128 degrees and the measure of angle TPQ is (4x+2) degrees.
Answer:
94°
Step-by-step explanation:
There is a five sided polygon PQRST in which the measure of angle PQR is 132 degrees, the measure of angle QRS is (4x-10) degrees, the measure of angle RST is (5x-11) degrees, the measure of angle STP is 128 degrees and the measure of angle TPQ is (4x+2) degrees.
Sum of angles in a pentagon = 540°
Hence:
PQR + QRS + RST +STP + TPQ = 540 °
132 + (4x-10)° + (5x-11)° + 128° + (4x+2) degrees = 540°
132 + 4x - 10 + 5x - 11 + 128 + 4x + 2 = 540
132 - 10 - 11 + 128 + 2 + 4x + 5x +4x = 540°
241 +13x = 540
13x = 540 - 241
13x = 299
x = 299/13
x = 23
What is m∠P?
m∠P in Pentagon PQRST = TPQ
TPQ = 4x + 2
= 4 × 23 + 2
= 94°

log(x+4)+ log(x)= log(x+4)
Answer: log(x+4) + log(x)=log(x+4)
Group like terms
log(x+4)-log(x+4)=-log(x)
Log((x+4)/(x+4))=-log(x)
log(1)= -log(x)
log(1)=0
=> 0=log(x)
x=10^0
x=1
Step-by-step explanation:
Before one can solve log questions, he/she must know the laws.

Help me please! I'm stuck and I need the answer now! Thx so much!
Answer:
34Step-by-step explanation:
Given
z = -3 + 5iConjugate of z is:
z' = -3 - 5iProduct zz' is:
zz' = (-3 + 5i)(-3 - 5i) = (-3)² - (5i)² = 9 - 25(-1) = 9 + 25 = 34If ,
[tex]\bold{z=-3+5i }[/tex]
so,conjugate of z
[tex]\overline{ z }[/tex]=[tex]\bold{-3-5i }[/tex]
Because, in argand plane [tex]\overline{ z }[/tex] is the reflection of z in x-axis.
so,
According to the question,
z[tex]\overline{z}[/tex]=(-3+5i)(-3-5i)
[tex]\bold{(-3)^2-(5i)^2 }[/tex]
[tex]\bold{9-25(-1) }[/tex]

a packet contains 6 maths books each of length 25 CM 20 cm and height 2 cm what is the volume of the packet
Step-by-step explanation:
1book valume = 25cm×20cm×2cm=1000cm³
a packet valume = 6×1000cm³ = 6000cm³
Answer:
216000 cm3
Step-by-step explanation:
length of packet = 6 × 25 cm = 150 cm
breadth of packet = 6 ×20 cm = 120 cm
height of packet = 6 × 2 cm = 12 cm
Now,
volume of packet = l×b×h = 150 cm × 120 cm × 12 cm
= 216000 cm3
How long does it take for an investment to quadruple in value if it is invested at 11% compounded
continuously? Type the exact answer as your answer (no decimal approximations).
Let's assume we have $100 and an interest rate of 7%. For the $100 to quadruple it means that the future value would be $400. Thus, because we are talking about compounding daily we will set us the equation as follows:
100 * (1+1.07)x = 400
Then we will take 400 and divide it by 100 getting:
1.07X = 4
Now we have encountered a problem where we do not know exponent, so we will use logarithm to calculate such and transform our equation to: Log1.07(4)=X
Using our calculator we will find that it takes about 20.4895 days to quadruple the money invested under 7% interest rate compounded daily.
2nd: Using the same $100 but with the rate of 5.5% compounded continuously we will be using A=PERT formula
where:
P (principal) is equal to hypothetical $100
E (e) is a mathematical constant, which is approximately 2.718
R (rate) is the interest rate, in our case it is 5.5%
T (time) is the time required for money to grow
A (amount) is the final amount desired, which is 4 times larger of $100, thus $400
We have the following:
400 = 100 * e0.055t
400/100 = e0.055t
4 = e0.055t
Then we will apply natural log to both sides of the equations and get the following:
ln(4) = ln(e0.055t)
Since e is the base of ln(x) the equation simplifies to:
ln(4) = 0.055t
Using the calculator to find ln(4) we are getting:
1.38629 = 0.055t
Lastly find t
t = 1.38629/0.055
t = 25.20535202
Plug the answers back to the original equation to verify the answers.
1st part of the question answer: t = 20.4895
2nd part of the question answer: t = 25.20535202

Answer:
A. Choice 2
B. Choice 1
C. Choice 2
D. Choice 1
Step-by-step explanation:
So basically if it's being multiplied by something each time, then it's choice 2 and if it's being add by something each time, then it's choice 1.
A. You can see in the diagram that each time you multiply the y-value by 2, so it's choice 2
B. In the equation you can tell that every time you will be adding 16, so choice 1
C. Since it's being multiplied by 0.75 each time, it's choice 2
D. Every time y grows by 12, so it's choice 1.

Guys I really need help on this please
Answer:
The answer is 26.2.
Step-by-step explanation:
To get the answer we take the miles done in the race, in this case 18.34 and he is 70% done the race. To find out how much total miles are in the race, we convert 70% into a decimal which is 0.70. then we have 18.34 and 0.70 to multiply. 18.34 x 0.70=26.2 Which is your answer.
Hope this helps!

Answer:
D
Step-by-step explanation:
It must be D because first of all you need the 1.01 because its a 1 percent increase and because when you write out what it would be for lets say 3 years it would be (310*1.01)*1.01)*1.01 so if we drop the parentheses because this is all multiplication you would have 310*1.01^3 which would be 3=t
Answer:
the pollen grain deposited were initially estimated at 310 with a annual increase rate of 1%
thus, there is an increase by 1.01 every year
for the first year after the year the grains were deposited there will be an increase of 310 (1.01)
similarly the following year will have an increase of 310(1.01)
(1.01) or 310(1.01)2-this 2 is a square
also the third, fourth, fifth....year will have an increase of 310(1.01)3-this 3 is a square, 310(1.01)4-this four is a square, 310(1.01)5-also this five is a square
respectively and thus, t years, there will be an increase of 310(1.01)t

A party planner wants 220 balloons in each of the 3 rooms. If balloons come in packages of 50 balloons, how many packages must be bought to fill the 3 rooms?
Answer:
14 packages.
Step-by-step explanation:
The total number of balloons needed is 3 * 220 = 660 balloons
To find the number of packages
660 / 50 = 13 with a remainder of 10.
Normally, you would round down, but not with this question. You need to buy a whole package to get the 10 left over balloons.
The answer is 14 packages.

Step-by-step explanation:
3. Q3) What is the smallest number of identical squares
that will fit in this rectangle?
Answer:
Minimum 3 squares.
Step-by-step explanation:
Let the number of identical squares that will fit in the rectangle = x
Sum of the area of the squares = Area of the given rectangle
x(Side length of the square)²= (length of the rectangle × width of the rectangle)
x(S)²= (40 × 90)
x(S)²= 3600 cm²
For the minimum numbers of the squares,
If x = 1,
S = √3600 = 60 cm
But the length of the rectangle is 40 cm, so can't be fitted in the rectangle.
If x = 2,
2S² = 3600
S² = 1800
S = √1800
S = 42.43 cm
Since, length of the rectangle is 40 cm, so the given square can't be fitted in the rectangle.
If x = 3,
3S² = 3600
S² = 1200
S = √1200
= 34.64 cm
Therefore, minimum 3 squares can be fitted in the given rectangle.
I'm so confused............................................
Answer:
Step-by-step explanation:
a is not less than 0 because it is to the right of 0 on the number line, so the first statement is false. The second statement is true. The absolute value of positive a is positive a, and since a is to the right of 0 on the number line, it is greater. The third statement is false. The absolute value of positive a is positive a, not 0.
Determine the value of x.

In the figure, AC is perpendicular to DB.
Which of the following statements is TRUE?
Answer:
B. Angle 5 and Angle 6 are complementary
Step-by-step explanation:
Definition of complementary- either of two angles who sum is 90°
As, Line AC and Line DB are perpendicular, Angle DO(the middle point)C is equal to 90°.
Angle DOC = 90°
Angle DOC = Angle 6 + Angle 5
Therefore, Angle 6 + Angle 5 are equal to 90°, so they are complementary.
Good luck!
