Answer:
16.27778 m/s
97666.6667 cm/min
Step-by-step explanation:
a. To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.
m/s = (58.6 * 5) /18 = 16.27778 m/s
b. 1 Kilometer/Hour = 1666.66666666667 Centimeter/Minute
so 58.6 * 1666.666 =97666.6667 cm/min

Nancy decides to roll a die three times.
What's the probability that she will roll all
even numbers?
1/8
Step-by-step explanation:
The probability of rolling an even number on one roll is 3/6 = 1/2. Assuming the rolls are independent, the probability of rolling an even number 3 times is ...
(1/2)(1/2)(1/2) = 1/8
The probability that Nancy rolls all even numbers in 3 rolls is 1/8

What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
4(x - 2) < 6(x+3)
Removing the parenthesis.
Step 1:
4x - 8 < 6x + 18
Subtracting -6x on both sides.
4x - 8 - 6x < 6x + 18 - 6x
Step 2:
-2x - 8 < 18
Add 8 on both sides.
-2x < 18 + 8
Step 3:
-2x < 26
Divide both sides by 2.
-x < 13
Multiply - on both sides.
The sign will change.
Step 4:
x > -13
We see that,
All the steps are given correctly.

The following section is a statement from the rental agreement Tim signed when he rented his car this past
weekend.
"Upon checkout, the fuel level of the vehicle will be determined by turning the vehicle on and visually inspecting the
fuel gauge. The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the
vehicle Renter. One copy of the Check-Out sheet will be given to the customer. Another copy will be kept with the
on-site records of the vehicle.
The rented vehicle must be returned with a minimum fuel level the same as that indicated on the Check-Out sheet.
A vehicle returned with a fuel level less than the approximate level indicated on the Check-Out sheet will be
completely refueled with on-site pumps. The price of the fuel used to refuel the vehicle will be added to the
Renter's total charge at a cost of $4.50 per gallon plus a S5.00 re-fueling charge
As a part of the check-out process, it is customary for a car rental agency to look over the car with the customer and
fill out the Check-Out sheet together. As Tim was walking around the car looking for damages that he didn't want to
be held responsible for, the agency representative turned on the car, took note of the fuel level, and indicated it on
the Check-Out sheet. Since Tim didn't have any questions, the clerk handed him the keys and a copy of the Check-
Out sheet and wished him well.

please help fast. - a pair of equations are shown below:
y = 7x - 8
y = 5x - 2
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
y = 7x - 8 → (1)
y = 5x - 2 → (2)
A
Solving by substitution
Substitute y = 7x - 8 into (1)
7x - 8 = 5x - 2 ( subtract 5x from both sides )
2x - 8 = - 2 ( add 8 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 7(3) - 8 = 21 - 8 = 13
Solution is (3, 13 )
B
The point of intersection of the graph of the 2 equations is the solution to the above equations.
That is point of intersection = (3, 13 )

Answer:
y = x^3 + x^2 − 20x
Step-by-step explanation:
Find the factors from the roots, then multiply the factors together.
f(x) = x³ + x² − 20x that is equation when x is equal to -5, 4, or 0 and for no other values of x.
What is polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Given that
f(x) = (x + 5)(x - 4)(x)
Multiply the factors together.
f(x) = (x + 5)(x² - 4x)
we have to open the brackets above
f(x) = x³ - 4x² + 5x² - 20x
Rearrange the likewise terms and apply the arithmetic operations,
f(x) = x³ + x² − 20x
This equation is true when x is equal to -5, 4, or 0 and for no other values of x.

I divided the number of days into 6.
Answer:
[tex]x = 240 days[/tex]
Step-by-step explanation:
If we know that Brad completes 1/6 of his project every 40 days, that means it will take him 40 x 6 days to complete this project. If where to write this down as an equation we get the following.
Let "x" be the total number of days Brad needs to finish his project, then....
[tex]\frac{1}{6} x = 40 days[/tex]

The partial factorization of x2 – 3x – 10 is modeled with algebra tiles. An algebra tile configuration. 1 tile is in the Factor 1 spot: and is labeled + x. 6 tiles are in the Factor 2 spot: 1 is labeled + x and 5 are labeled negative. 18 tiles are in the Product spot: 1 is labeled + x squared, 2 are labeled + x, the 5 tiles below + x squared are labeled negative x, and the 10 tiles below the + x tiles are labeled negative. Which unit tiles are needed to complete the factorization?
Answer:
2 positive unit tiles is needed
Step-by-step explanation:
Given the expression x^2 – 3x – 10, the partial factorization is as shown;
x^2 – 3x – 10
= x^2 +2x – 5x – 10
= x(x+2)-5(x+2)
= (x-5)(x+2)
Note that negative values are represented as tiles labelled below (negative tiles) while positive values are tiles labelled above (positive tiles)
From the second line we can see that first term 1 is labeled + x squared, second is labelled +2x (two positive tiles above), then the 5 tiles below + x squared are labeled negative x, and the 10 tiles below the + x tiles are labeled negative.
Hence base on the partial factorization and the underlined statement, we can see that 2 positive unit tiles is needed to complete the factorization

Answer:
[tex]Area =\frac{10x + 15}{2}[/tex] in both cases
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have the following given parameters
Green Section: Dimension: x by 2
Orange Section: Dimension: 2 by [tex]1\frac{1}{2}[/tex]
Purple Section: Dimension: 3 by (x + [tex]1\frac{1}{2}[/tex])
Solving (a): Area of the flag as a sum of each section
We simply calculate the area of each section.
[tex]Area = Length * Width[/tex]
For the green section;
[tex]Area = x * 2[/tex]
[tex]Area = 2x[/tex]
For the orange section
[tex]Area = 2 * 1\frac{1}{2}[/tex]
[tex]Area = 3[/tex]
For the purple section
[tex]Area = 3 * (x + 1\frac{1}{2})[/tex]
[tex]Area = 3 * (x + \frac{3}{2})[/tex]
[tex]Area = 3x + \frac{9}{2}[/tex]
Total Area = Sum of the above areas
[tex]Area = 2x + 3 + 3x + \frac{9}{2}[/tex]
Collect Like Terms
[tex]Area = 2x + 3x+ 3 + \frac{9}{2}\\[/tex]
[tex]Area = 5x+ \frac{6+9}{2}[/tex]
[tex]Area = 5x+ \frac{15}{2}[/tex]
[tex]Area =\frac{10x + 15}{2}[/tex]
Solving (b): Area of the flag as a product
From the attachment,
[tex]Length = 2 + 3[/tex]
[tex]Length = 5[/tex]
[tex]Width = x + 1\frac{1}{2}[/tex]
[tex]Area = Length * Width[/tex]
[tex]Area = 5(x + 1\frac{1}{2})[/tex]
[tex]Area = 5(x + \frac{3}{2})[/tex]
[tex]Area = 5x + \frac{15}{2}[/tex]
Take LCM
[tex]Area = \frac{10x + 15}{2}[/tex]
