helppp plzzzzz. a sum of money put out at compund interest in increased by Rs.180 at the end of first year and by Rs. 188.10 at the end of second year. find out the sum and rate of interest
9514 1404 393
Answer:
₹172.25 at 4.5%
Step-by-step explanation:
The growth factor is the ratio of the values at the end and beginning of the second year:
multiplier = 188.10/180 = 1.045 = 1 + 4.5%
The amount put out is the amount at the end of the first year, divided by this growth factor.
P = A/(1+r) = 180/1.045 = 172.25
The sum put out is ₹172.25, and the rate of interest is 4.5%.

Find the rectangular coordinates of (7, 150°)
Answer:
The coordinates are (-7sqrt(3)/2, 7/2).
Step-by-step explanation:
The rectangular coordinates from polar coordinates is found by:
x = r*cos(theta)
y = r*sin(theta)
Substituting the given values, we get:
x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2
y = 7*sin(150 deg) = 7*(1/2) = 7/2
The coordinates are (-7sqrt(3)/2, 7/2).
I hope this helps! :)

Answer:
c)[tex] \frac{x + 2}{x - 3} . \frac{4}{x + 2} [/tex]Using PEMDAS solve
22/2x3
Okay, let me help you.
PEMDAS is just order of operations. P - Parentheses, E - Exponents, M - Multiplication, D - Division, A - Addition, and S - Subtraction.
/ this symbol means to DIVIDE.
Since division is at the beginning of the equation, you start with 22 ÷ 2 x 3
Let's break this down...
2 x 3 = 6
22 ÷ 6 = 3.66... and on with the 6's.
The answer to this equation, is
3.66
The chart below describes the commissions earned by four different sales people. Sales Person Commission Earned Time on Sales Floor Alex $220 10 Hours Beth $40 120 minutes Cleo $120 300 minutes David $180 360 minutes Which sales person earned the most money per hour? A Alex B Beth C Cleo D David
Answer:
ALEX
Step-by-step explanation:
Because if u look it says ten minutes an e has 220 so that equals to almost 3'500 dollars Im only in 7th grade good luck
Answer:
Step-by-step explanation:
Heya, the correct answer is David. The tricky part is the Hours and minutes difference. by dividing 360 by 6 we'll get 60. That equals an hour. Which is what the original answerer got wrong. So, If we divide 180 by 6 we get 30. So actually, there is an 8-number difference between Alex's and David's answers. With David being right. 22-30

Answer:
We get the value of x: x= 2
Step-by-step explanation:
Since the triangles are similar, the ratios of the lengths of corresponding sides are same.
We can use proportions to find the value of x
The proportion will be:
[tex]\frac{BD}{DA}=\frac{BE}{EC}[/tex]
Now putting there values we can find value of x
We have:
BD = 6, DA = 4, BE = x+1, EC =x
Putting values
[tex]\frac{BD}{DA}=\frac{BE}{EC}\\\frac{6}{4}=\frac{x+1}{x} \\Cross\:Multiply\\6x=4(x+1)\\6x=4x+4\\6x-4x=4x+4-4x\\2x=4\\x=\frac{4}{2}\\x=2[/tex]
So, we get the value of x: x= 2

Step-by-step explanation:
Which value is in the domain of f(x)?
Answer: x = 4
Step-by-step explanation:
Here we have a piecewise function.
One piece works for values of x such that: -6 < x < 0
And the other piece works for values of x such that: 0 < x ≤ 4
Then the domain of this function is:
D = (-6, 0) U (0, 4]
Notice that, becuse we use the symbols ><, the values of x:
x = -6
x = 0
Do not belong to this domain.
While becuase we use the symbol ≤ in the right end, the value x = 4 does belong to the domain.
Then for the given options, the only value that belongs to the domain is the third option, x = 4.

Find the percentage of change round to the nearest cent whole percent if necessary state whether the percent of change is an increase or decrease
3 months to 5 months
5 to 10
$0.32 to $.37
Answer with explanation:
Percentage change = [tex]\dfrac{Change}{Previous\ value}\times100[/tex]
a) 3 months to 5 months
Change = 5 - 3 ( increase )
Percentage change = [tex]\dfrac{2}{3}\times100\%=66.67\%[/tex] , it is an increase .
b) 5 to 10
Change = 10-5 = 5 ( increase)
Percentage change = [tex]\dfrac{5}{5}\times100\%= 100\%[/tex], it is an increase .
c) $0.32 to $.37
Change = 0.37-0.32 = 0.05 ( increase)
Percentage change = [tex]\dfrac{0.05}{0.37}\times100\%=13.51\%[/tex], it is an increase .
