Answer:
The value is [tex]m = 0.9022[/tex]
Step-by-step explanation:
From the question we are told that
The length of the treads is [tex]a = 9 \ inch[/tex]
The length of the risers is [tex]b = 8.12 \ inch[/tex]
Generally the slope of the staircase is
[tex]m = \frac{b}{a}[/tex]
=> [tex]m = \frac{8.12}{9}[/tex]
=> [tex]m = 0.9022[/tex]
A line has an undefined slope and passes through the poimt (7,11) write the equation of the line
Answer:
x = 7
Step-by-step explanation:
An undefined slope indicates the line is vertical and parallel to the y- axis with equation
x = c ( c is the value of the x- coordinates the line passes through )
the line passes through (7, 11 ) with x- coordinate 7 , then
x = 7 ← equation of line

Which function is equivalent to g(x) = x2+ 15x - 54?
Answer:
g(x) = (x+18) (x-3)
Step-by-step explanation:
x²-3x+18x-54
x(x-3)+18(x-3)
(x-3)(x-18)
The function equivalent to [tex]g(x) = x^{2} +15x-54[/tex] is [tex](x - 3) (x- 18)[/tex].
Here, the function is given as;
[tex]g(x) = x^{2} +15x-54[/tex]
What is Function?
A function is defined as a relation between a set of inputs having one output each.
Now, function is given as;
[tex]g(x) = x^{2} +15x-54\\g(x) = x^{2} +18x-3x-54\\g(x) = x(x+18)-3(x+18)\\g(x) = (x+18)(x-3)[/tex]
Hence, The function equivalent to [tex]g(x) = x^{2} +15x-54[/tex] is [tex](x - 3) (x- 18)[/tex].

one number is two more than triple a second number. Their sum is 30. what is the smaller number
Answer:
7
Step-by-step explanation:
We can solve this problem by making an equation.
Let x represent the second number
3x + 2 will be the first number because it is 2 more than triple x
This makes our equation:
3x + 2 + x = 30
Combine like terms
4x + 2 = 30
Subtract 2 from both sides
4x = 28
Divide both sides by 4
x = 7
The smaller number aka the second number is 7

If tax was 8.25% on the $220 total for the items purchased at Target, what was the total cost of the items including tax?
Answer:
$238.15
Step-by-step explanation:
8.25% = 8.25/100 or 0.0825
Multiply 0.0825 and 220 to get $18.15. That's how much the tax is.
Add 220 and 18.15 to get $238.15
Answer:
$238.15
Step-by-step explanation:
To find the total cost of the items including tax you will need to multiply the cost of the items by the decimal form of 8.25%.
The decimal form of 8.25% is .0825. When turning percents to the decimal form we move the decimal two places to the left.
Now we multiply!
(220)(.0825) = 18.15
Now add 18.15 onto the 220 to find the total cost including tax:
220 + 18.15 = 238.15
Therefore, the total cost of the items including tax is $238.15.
I hope this helps!!
