The value of n for the exponential expressions will be 2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given expression will be solved as follows:-
[tex]1.9 \times 10^7 = (1 \times 10^5)(1.9 \times 10^n)[/tex]
[tex]10^7 = 10^5\times 10^n[/tex]
[tex]10^7 = 10^{n+5}[/tex]
Use the property of exponents which states that if the base is the same and the numbers with the exponent are in multiplication then the powers will be added.
7 = n + 5
n = 7 - 5
n = 2
Therefore, the value of n for the exponential expressions will be 2.

Find the ratio of a:b, if 2a-b/6=b/3
Answers
Answer:
[tex]\frac{a}{b}=\frac{1}{4}[/tex]
Thus, the ratio is:
a:b = 1:4
Step-by-step explanation:
Given the expression
[tex]2a-\frac{b}{6}=\frac{b}{3}[/tex]
[tex]\mathrm{Add\:}\frac{b}{6}\mathrm{\:to\:both\:sides}[/tex]
[tex]2a=\frac{b}{2}[/tex]
Divide both sides by 2
[tex]\frac{2a}{2}=\frac{\frac{b}{2}}{2}[/tex]
[tex]a=\frac{b}{4}[/tex]
Divide both sides by b
[tex]\frac{a}{b}=\frac{1}{4}[/tex]

a curcular track is 1/4 completing each mile every 1/15 mile
Answers
Answer:
s = 3.75 miles/hour
Step-by-step explanation:
Distance covered = 1/4 of a mile
Time taken = 1/15 of an hour
We need to find the speed of the track. We know that,
[tex]s=\dfrac{d}{t}\\\\=\dfrac{\dfrac{1}{4}}{\dfrac{1}{15}}\\\\=3.75\ mi/h[/tex]
So, the required speed is 3.75 miles/hour.

Answers
Answer:
t = 5
Step-by-step explanation:
It's asking what t needs to equal for the equation to be equivalent to -44.
-10t + 6 = -44
-10t = -50
t = 5
check
-10(5) + 6 = -44
-50 + 6 = -44
-44 = -44
Answer:
t = 5
Step-by-step explanation:
h(t) = -10t + 6
After that you just write -10t + 6 = -44
Subtract 6 from -44
-44 - 6 = -50
So you will have
-10t = -50
Then you do -10t/-10 = -50/-10
-10t/-10 = t
-50/-10 = 5
So the final answer is t = 5
For proof, plug 5 in.
-10(5) + 6 = ?
-10(5) = -50
-50 + 6 = -44

Is 8:14 and 29:35 are proportional
Answers
Answer:
yes they are proportional
Answer: It's not
Step-by-step explanation: Proportionality (if that's a word) is basically changing a fraction to a proportion. So 8:14 is basically 4:7, and 29:35 is just that since it can't be simplified. Obviously the two aren't equal, so its not proportional to each other.

How many soultions? -4x-7+10x=-7+6x
A. No solutions
B. Exactly one solution
C. Infinitely many solutions
Answers
Answer:
C. Infinitely many solutions.
Step-by-step explanation:
-4x - 7 + 10x = -7 + 6x
Combine like terms on the left side. Rearrange the right side.
6x - 7 = 6x - 7
Add 7 to both sides.
6x = 6x
Subtract 6x from both sides.
0 = 0
0 = 0 is a true statement.
Both sides are equal, so all real values of x make the equation true.
Answer: C. Infinitely many solutions.

Find the sales tax. Then find the total cost of the item.
Sales Tax
Selling Price Rate of Sales Tax Sales Tax
$40.00
7%
?
The sales tax is $
Answers
Answer:
Step-by-step explanation:
You must state the "price before tax". Let this be P. Also, you must state the sales tax rate. Let this be r, where r is a decimal fraction.
Then the sales tax is rP, the product of the tax rate and the "price before tax."
The total cost of the item (for which it is sold) is (P + rP)($40).
If P = $40 and the sales tax rate is 7%, then
this total cost is (1 + 0.07)P = 1.07P = $42.80
Your question would be clearer if you wrote it like this: Given that the base price of an item is $40 and that the sales tax rate is 7%, find the total cost of the item with tax. That would be (1 + 0.07)($40), or $42.80.
The sales tax is $42.80 - $40 = $2.80.
Answer:
Sales tax: 2.8$
Total cost: 42.8$
Step-by-step explanation:
the percentage of tax is that much of the total price. if there is 50% sales tax (unrealistic) and the item costs 100 dollars without any tax, then the tax would be 50 dollars. To find this, turn the percent into a decimal (move the decimal place to the left twice) and multiply that by the price. To do this with this problem, use this strategy. 40 times .07=2.8. 2.8 plus 40= 42.8. hope this helps!!
