Given:
The number is 0.1588.
To find:
The scientific notation of given number.
Solution:
If a number expressed as a number between 1 and 10 is multiplied by a power of 10, then it is known as scientific notation of the number.
The given number is 0.1588.
Here, leading digit is 1.
There are no zeroes to the right of the decimal point before the leading digit 1.
Leading digit 1 is 1 digit to the right of the decimal value. So,
[tex]0.1588=1.588\times 10^{-1}[/tex]
Therefore, the scientific notation of given number is [tex]1.588\times 10^{-1}[/tex].

Race day has finally arrived, and the event is about to begin. Each racer must complete one lap on the circular track, which has a radius of 15 meters. You find yourself racing against Ali Al Jouda! He holds the record for the KSAA U14 100m race. You are worried but motivated! According to his record, he runs at an average speed of 8.4 m/s. Your average speed is 7 m/s. How far will you have run by the time Ali crosses the finish line?
Answer:
78.54 meters
Step-by-step explanation:
circular path
radius = 15 meters
First we have to calculate the circumference of the circular path = 2[tex]\pi r[/tex]
= 2 * [tex]\pi * 15[/tex]
= 94.285 meters ( total distance to be covered )
For Ali running at a speed of 8.4 meters/ seconds
It will take him : ( 94.285 / 8.4 ) seconds
= 11.22 seconds
You running at a speed of 7 meters/seconds
hence at 11.22 seconds when Ali must have crossed the finish line you must have covered ;
(11.22 * 7 ) meters
= 78.54 meters

the sale tax rate on groceries in a certain state is 9% if the price of a grocery item before sales tax is g dollars, which expression represents the cost of the grocery item including sales tax?
Step-by-step explanation:
g + 0.09g = the final price
multiplying 0.09(9/100) with g will give you the tax
then you add it up to get the final cost.
The expression representing the cost of the grocery item including sales tax is 1.09g.
What is Percentage?Percentage is a dimensionless number and it has no measurement units.
It is usually denoted by the sign %. Sometimes it has also used in the abbreviated form 'pct.'.
Percentage of a number is the quotient of the number dividing with the whole and then multiply with 100. The reverse calculation can be done to find the number corresponding to a percentage.
Price of a grocery item before sales tax = g dollars
Sales tax rate on groceries = 9%
Amount of sales tax = 9% × g
= (9/100) × g
= 0.09 g
Total cost of the grocery = g + 0.09g
= 1.09g
Hence the total cost of the grocery item including sales tax is 1.09g.

The formula for simple interest is where I is the amount you will pay in interest, r is the rate at which interest will accrue, P is the principal (amount borrowed), and m is the number of times the interest is applied.
Answer:
Kindly check explanation
Step-by-step explanation:
The simple interest formula (I) is the product of the principal, interest rate and the number of times interest is applied
Mathematically,
Simple interest (I) = principal(p) * rate(R) * time (t)
For instance, if a principal amount of $200 is borrowed at a rate of 5% per annum for 3 years. The simple interest on the amount borrowed will be :
Simple interest = $200 * 5% * 3
Simple Interest = $200 * 0.05 * 3
Simple Interest = $30
When traveling the probability of missing two flights in a row is .06. The probability of missing a single flight is .19. Are the two flights independent? ?
Answer:
Suppose that we have two events, event A and event B.
Where the probability of event A is Pa, and the probability of event B is Pb.
We say that events A and B are independent if the probability of both events happening is equal to the product of the individual probabilities.
Probability of event A and B = Pa*Pb.
In this case we have:
A = missing a single flight
B = missing a single flight.
Pa = 0.19 = Pb.
And we know that the probability of missing two flights is 0.06
Let's see if this is equal to the product of the individual probabilities:
Pa*Pb = 0.19*0.19 = 0.036
So the joint probability is smaller than the one given, this means that the events are not independent and that if you miss one plane, the probability of missing the next one has a small increase.

Write in slope-intercept form (solve for y): 5x - 2y = 8
Answer:
y = 5/2 x - 4
Step-by-step explanation:
For slope-intercept form, just solve for y:
5x - 2y = 8
[tex]\frac{5x}{2} - \frac{8}{2} = \frac{2y}{2}[/tex]
5/2 x - 4 = y or
y = 5/2 x - 4
The slope intercept form is y= 5/2x - 4.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have the Equation
5x - 2y = 8.
As, we know from the slope intercept form
y= mx + b
So, 5x - 2y = 8
5x - 8 = 2y
5/2x - 8/2 = y
y= 5/2x - 4
where slope is 5/2 and y intercept is -4.

Karen owns a seafood restaurant. She orders trout from an online retailer. Each pound of trout costs $30 and the company charges a $2 fee for shipping the order. However, if Karen orders 10 or more pounds, the Trout costs only &24 per pound, but the shipping fee is $6. Which piecewise function models the cost of x pounds of Trout?
Let, number of pounds of trout is x and their price is C.
For, x < 10 :
Price per pound is 30 .
C = 30x + 2 ....1 )
For, x ≥ 10 :
Price per pound is 24 .
C = 24x + 6 ....2 )
Therefore, total cost is :
[tex]C =\$ \left \{ {{30x+2 \ \ \ \ x<10} \atop {24x +6 \ \ \ \ x \ge 10}} \right.[/tex]
Hence, this is the required solution.
Answer:
30x+2, 0<x<10
