Answer:
x = 75 hope this helped
Step-by-step explanation:
The true solution to the equation is,
⇒ x = 75
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
Now, We can simply as;
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
⇒ 2 ln 2x - ln 10x = ln 30
⇒ ln (2x)² - ln 10x = ln 30
⇒ ln (2x)² / 10x = ln 30
⇒ 4x² / 10x = 30
⇒ 4x = 300
⇒ x = 75
Thus, The true solution to the equation is,
⇒ x = 75

Alex rents a car for one day the charge is $28 plus $0.50 per mile Alex wants to spend exactly $30 how many miles can he drive
Answer:
4 milesStep-by-step explanation:
Let the miles is x:
28 + 0.5x = 300.5x = 30 - 280.5x = 2x = 2/0.5x = 4It seems incorrect but Alex can drive 4 miles
work out the circumference of a cirlce with a diameter of 1.8m
Answer:
5.56 m
Step-by-step explanation:
Circumference = 2πr
r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:
1.8 ÷ 2 = 0.9
Circumference = 2 × π × 0.9
= 5.56 m ( in 3 significant figures )

AKS 19 -- Dan is driving with an average speed of s. He is driving a total distance of d. What formula represents the total time of his trip? Question 2 options: t=ds t = d s t=ds t=d-s t=sd
Answer:
[tex]t=\dfrac{d}{s}[/tex]
Step-by-step explanation:
Dan is driving with an average speed of s. He is driving a total distance of d.
The average speed of an object is given by :
Average speed = total distance/total time
Let b the time of his trip
So,
[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]
So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].

What is the approximate area of the shaded sector?
A. 38 cm2
B. 96 cm2
C. 302 cm
D. 603 cm?
Answer:
C. [tex] 302 \: {cm}^{2} [/tex]
Step-by-step explanation:
[tex]Area \: of \: sector = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 \degree}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 }{360 } \times 3.14 \times {(16)}^{2} \\ \\ = \frac{108,518.4 }{360 } \\ \\ = 301.44 \\ \\Area \: of \: sector \approx \: 302 \: {cm}^{2} [/tex]
what is the value of x in simplest radical form?
Answer:
25
Step-by-step explanation:
For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.
Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.
NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!
With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.
This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.
This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.
And that, my friend, is your answer. Hope this helped :)
What is the perimeter of a square whose area is 289 square feet?
A. 17 feet
B. 48 feet
C. 68 feet
D. 73 feet
Answer:72.25
Step-by-step explanation:
write an equation of the line that passes through the point (0,3) and whose slope is 2
Answer:
y - 2x = 3
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:
y - 3 = 2(x - 0), or
y - 3 = 2x, or
y - 2x = 3
Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b: it is 3.

Answer:
We have the value as;
8x/5
Step-by-step explanation:
Here, we want to get the breakdown of the given expression
We have (x^2 - 9) as (x-3)(x + 3)
So we have;
2x/(x + 3) * (x-3)(x+3)/5 * 4/(x-3)
= 2x * 4/5= 8x/5

Write an equation that relates the change c he gets back in dollars to the cost b, in dollars, of his purchases. Which variable represents the independent variable? How much change does he get back if his purchases total $12.83?
Answer:
b= 12.83
c= 7.17
Variable "c" is independent because it does not change. Jim receives $7.17 back.
The letters in the word JANUARY were put in a bag and drawn randomly. What is the probability of picking an a?
Answer: 2/7
Step-by-step explanation:
There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"
2/7
there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.
Hope this helps :3

Anyone know how to solve this? Im losing brain cells
Answer and Step-by-step explanation:
The answer is A.
y = x + 2 and y = -2x + 4
This is because:
- The graph going from left to right matches the first equation, in which the graph has a slope of 1 and has a y-intercept at (0, 2).
- The graph going from right to left matches the second equation, in which the graph has a slope of -2 (Since it is going from right to left), and has a y-intercept at (0, 4).

The floor of a cargo truck is 22 1/2 square feet. What is the volume of the storage space in cubic feet if the truck is 7 1/5 feet high? Show, label, and explain your work.
Answer:
162 ft^3
Step-by-step explanation:
volume = area of base * height
V = 22 1/2 ft^2 * 7 1/5 ft
Change the mixed numerals into fractions.
V = 45/2 ft^2 * 36/5 ft
Multiply the fractions.
V = 45/2 * 36/5 ft^3
Switch the denominators.
V = 45/5 * 36/2 ft^3
Simplify each fraction.
V = 9 * 18 ft^3
V = 162 ft^3
