Answer:
The value of "X" would be 2.
To solve for x, you'd have to get it by itself. To do so, you'd simplify both sides by solv8ng the exonents of each side (2^2 = 4) and (2^3 = 8). This leaves you with 4x = 8, which you'd then divide both sides by 4. Thus getting 2 as a final answer.

What does 0.9a - 2.7b =
Krutika and Natasha win some money and share it in the ratio 4:3. Krutika gets £7 more than Natasha. How much did they get altogether?
Answer:
49
Step-by-step explanation:
The computation of the total amount is shown below:
Let us assume the natasha be 4x
And, the krutika be 3x
Now as per the situation
4x = 3x + £7
x = £7
For natasha = 4(7) = 28
For krutika = 3(7) = 21
So, the total amount is
= 28 + 21
= 49

Mr Lee drove from City P to City Q, which are 600 km apart. During his return journey,
his average speed was increased by 7 km/h and the time taken was 15 minutes less.
() If he drove at an average speed of x km/h on his journey from City P to City Q,
formulate an equation in x and show that it reduces to x2 + 7x – 16 800 = 0.
(ii
) Solve the equation x² + 7x - 16 800 = 0, giving both your answers correct to
2 decimal places.
(iii) Find the time taken for the return journey.
Answer:
i. x² + 7x - 16800 = 0 ii. x = 126.16 km/h or -133.16 km/h iii. 5.01 h
Step-by-step explanation:
i. If he drove at an average speed of x km/h on his journey from City P to City Q formulate an equation in x and show that it reduces to x2 + 7x – 16 800 = 0.
For the first journey from City P to City Q, with Mr Lee moving at an average speed of x km/h, he reaches there in time, t and covers the distance, d = 600 km
So, xt = 600 (1)
On his return journey from City Q to CIty P, his average speed increases by 7 km/h, so it is (x + 7)km/h and his time is 15 minutes less than his first journey. 15 min = 15/60 h = 0.25 h, we have that his time for the journey is (t - 0.25) h. Since the distance covered is the same d = 600 km,
We have (x + 7)(t - 0.25) = 600 (2)
Expanding the brackets, we have
xt - 0.25x + 7t - 0.25(7) = 600
xt - 0.25x + 7t - 1.75 = 600
From (1) t = 600/x and xt = 600
Substituting these into the equation, we have
600 - 0.25x + 7(600/x) - 1.75 = 600
simplifying
-0.25x + 4200/x - 1.75 = 600 - 600
-0.25x + 4200/x - 1.75 = 0
multiplying through by x, we have
-0.25x² + 4200 - 1.75x = 0
dividing through by -0.25, we have
-0.25x²/-0.25 + 4200/-0.25 - 1.75x/-0.25 = 0
x² - 16800 + 7x = 0
re-arranging, we have
x² + 7x - 16800 = 0
ii. Solve the equation x² + 7x - 16 800 = 0, giving both your answers correct to 2 decimal places.
Using the quadratic formula, we solve x² + 7x - 16800 = 0 for x
So, [tex]x = \frac{-7 +/-\sqrt{7^{2} - 4 X 1 X -16800} }{2 X 1}\\x = \frac{-7 +/-\sqrt{49 + 67200} }{2} \\x = \frac{-7 +/-\sqrt{67249} }{2} \\x = \frac{-7 +/- 259.32}{2} \\x = \frac{-7 + 259.32}{2} or x = \frac{-7 - 259.32}{2} \\x = 252.32/2 or x= -266.32/2\\x = 126.16 km/hor x = -133.16 km/h[/tex]
So, x = 126.16 km/h or -133.16 km/h
iii. Find the time taken for the return journey
The time taken for the return journey is t' = t + 0.25. Now. t = 600/x
Since x cannot be negative, we use x = 126.16 km/h.
So, t = 600/x = 600/126.16 = 4.76 h
t' = t + 0.25
t' = 4.76 + 0.25
t' = 5.01 h

The population of deer in a forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 percent per year.
Based on this prediction, about how many years will it take for the population to double in size?
Use the equation P = P.(1 + r)
in which Po represents the initial population size, rrepresents the growth rate, trepresents the number
of years, and Prepresents the final population size.
A.
5.0 years
B.
1.8 years
OC. 0.3 year
OD.
3.8 years
Answer:
35 years
Step-by-step explanation:
Given that:
Current deer population, P0 = 800
Growth rate = 20% yearly
For the population to double in size, P = 2 * P0 = 2 * 800 = 1600
t = number of years
Using the relation :
P =P0(1 + r)^t
1600 = 800(1 + 0.2)^t
1600 / 800 = (1.02)^t
2 = (1.02)^t
t = log2 / log(1.02)
t = (0.3010299 / 0.0086001)
t = 35.003069
t = 35 years

A total of $5000 is invested part of 6% and the remainder at 12% how much is invested at each rate if the annual interest is $480
Answer:
for 12% it would be $3,000
And, for 6% it would be $2,000
Step-by-step explanation:
The computation of the amount invested at each rate is shown below:
Let us assume the amount invested at 12% be x
So, the $5,000 - x be invested at 6%
The total interest earned is $480
So the equation would be
0.12x + 0.06($5,000 - x) = $480
0.12x + $300 - 0.06x = $480
0.06x = $80
x = $3,000
So for 12% it would be $3,000
And, for 6% it would be $2,000

The x-intercepts of the function are 3 and -9, which are a lower bound and an upper bound for the possible values of the length of the storage bin.
The x-intercepts of the function are 3 and -9, which are a lower bound and an upper bound for the possible values of the width of the storage bin.
The x-intercepts of the function are 0 and 6, which are a lower bound and an upper bound for the possible values of the length of the storage bin.
The x-intercepts of the function are 0 and 6, which are a lower bound and an upper bound for the possible values of the width of the storage bin.
Answer:
The x-intercepts of the function are 0 and 6, which are a lower bound and an upper bound for the possible values of the width of the storage bin.
Step-by-step explanation:
Given

Required
Which is true about the x intercept
To do this, we make A(x) = 0.
Substitute 0 for A(x) in [tex]A(x) = x^2 - 6x[/tex]
[tex]0 = x^2 - 6x[/tex]
Rewrite as:
[tex]x^2 - 6x=0[/tex]
Factorize:

Samantha wants to buy a house and plans to rent the apartment located in the basement for extra income. The house has a purchase price of $200,000 and she will make a 10% down payment. Samantha has qualified for a 30 year mortgage with a fixed rate of 5.875%. Approximately how much rent should she charge for the apartment in order to cover her monthly mortgage payment if she only wants to spend $500 a month of her own money?
Answer:
$567.07
Step-by-step explanation:
Given that :
Purchase price = $200,000
Number of years = 30
Rate = 5.875%
Down payment = 10%
Hence, mortgage amount :
Purchase price - down payment
200,000 - (0.1 * 200000)
200,000 - 20,000
= $180,000
Using a mortgage calculator :
Mortgage amount = 180,000
Mortgage term = 30 years
Interest = 5.875%
Monthly payment will be : $1067.07
Hence, if she only wants to $500 from her own money, A rent of ($1067.07 - $500) = $567.07 will need to be charged
