Answer:
Mandy is 1.613 m tall
Step-by-step explanation:
Let us consider
Mary is A, Misa is B and Mandy is C
According to question,
A + B + C = 4.84 m...... (i)
From qsn
9 cm/0.009 m
= 9 cm/ 0.9 cm
= 10 cm
= 0.1 m
Then, A is 0.1 m shorter than B
i.e. A= B - 0.1 m
Also, B is 0.05 m taller than C
i.e B = C + 0.05m
We have to find height of C ( Mandy)
From eqn (i)
C = 4.84 - B - A
or, C = 4.84 - (C + 0.05) - ( B - 0.1)
or, C = 4.84 - C - 0.05 - B + 0.1
or, 2C = 4.89 - B
or, 2C = 4.89 - ( C + 0.05)
or, 2C = 4.89 - C - 0.05
or, 3C = 4.84
or, C = 4.84/3
or, C = 1.613 m
What is the inverse of the function f(x) = 2x – 10?
Answer:
The inverse f-1(x) = ( x + 10)/2.
Step-by-step explanation:
f(x) = 2x - 10
Find x in terms of f(x):
2x = f(x) + 10
x = (f(x) + 10))/ 2
Replace x by the inverse f-1(x) and f(x) by x:
f-1(x) = (x + 10)/2.

If the reserve rate is 3% and a bank receives a deposit of $16,000, how much of the $16,000 is the bank free to loan out?
The reserve rate is what the bank keeps. This means it can loan out ( 100% -3%) = 97% of the deposit.
16,000 x 0.97 = $15,520 can be loaned out.

In 2015, the city of Miami had a population of 441,000 people and an area of 36 square miles. What was the population density of Miami, in people per square mile, in 2015? 10,750 12,250 14,250 16,750
Answer:
12,250
by dividing the 441000 by 36, I got the answer.
The population density of Miami, in people per square mile, in 2015 was 12,250
The given parameters are:
Population = 441,000 peopleArea = 36 square milesThe population density of a place is the ratio of the population to the unit square area.
So, we have:
[tex]Density=\frac{Population}{Area}[/tex]
Substitute known values
[tex]Density=\frac{441000}{36}[/tex]
[tex]Density=12250[/tex]
Hence, the population density of Miami, in people per square mile, in 2015 was 12,250

Find the equivalent equation that results from adding 5 to both sides first and then multiplying
both sides by 2. Show each step. You do not have to solve the equation at the end.
Answer:
5d = 30
Step-by-step explanation:
1. first you need to add 5 to both sides
d-4+5 = 2+5
2. then you need to combine like terms
d+1 = 7
3. after that you have to multiply both sides by 5
5(d+1) = 7(5)
4. simplify
5d + 5 = 35

Which Statement is not true based on the figures below?
A statement that is not true based on the figures would be A; CD = JK
WE are given the figure of two similar pentagon figure that are;
ABCDE and JKLMN
Similar figure are zoomed in or zoomed-out (or just no zoom) version of each other. For two similar figures, the pair-by-pair similar angles of those two similar figures are called corresponding angles tthat are of same measurement.
Thus, we can see that the sides are similar to each other.
AB = JK
CB = LK
CD = LM
DE = MN
AE = JN
Since CD = JK is not valid
Therefore, we can conclude that the first statement is incorrect.
Hence, the answer is A.

Step-by-step explanation:
By the definition of alternate interior angle:
3x-2=2x+5
3x-2x=5+2
x=7
Note:if you need to ask any question please let me know.
Answer:
x = 7
Step-by-step explanation:
since these are alternating interior angles, these two expressions will be = to each other
2x+5=3x-2
subtract the 2x from both sides
5=x-2
add the 2 to both sides

How can $500 be divided between four people so that each person gets $20 more than the person before.
Answer:
$95, $115, $135, $155
Step-by-step explanation:
If the first person gets x dollars:
the next person gets 20 more, so x + 20 dollars
the next person gets x + 40 dollars
and the last person gets x + 60 dollars
We add all these allocations together, and we get $500
x + (x + 20) + (x + 40) + (x + 60) = 500
Combine like terms
4x + 120 = 500
Subtract 120 on both sides
4x = 380
Divide by 4 on both sides
x = 95
So the first person gets $95.
The second person must get $115
The third must get $135
And the fourth must get $155
Checking our work:
95 + 115 + 135 + 155 = 500
