Answer:
4435236
Step-by-step explanation:
Total digits of code = 6
Code options for first 4 digits = any of 1 - 9 = 9 options
Code option for last 2 digits = A - Z = 26 options
Code number 1 = 9 possible values
Code number 2 = 9 possible values
Code number 3 = 9 possible values
Code number 4 = 9 possible values
Code number 5 = 26 possible values
Code number 6 = 26 possible values
Hence, total number of possible access codes :
9 * 9 * 9 * 9 * 26 * 26
9^4 * 26^2
= 4435236 possible ways
Some rectangles have an area of 36 cm². Let the variable W represent the width of these rectangles. Which expression represents the perimeters of these rectangles?
Answer:
The perimeter of the rectangle is expressed as; [tex]P = \frac{72 \ + \ 2W^2}{W}[/tex]
Step-by-step explanation:
Given;
area of the rectangle, A = 36 cm²
width of the rectangle, = W
Let L represent the length of the rectangle,
A = L x W
[tex]L = \frac{A}{W} = \frac{36}{W}[/tex]
The perimeter of the rectangle is calculated as;
P = 2(L + W)
Substitute the value of L into the above equation;
[tex]P = 2(L + W)\\\\P = 2 (\frac{36}{W} + W)\\\\P = 2 (\frac{36 + W^2}{W} )\\\\P = \frac{72 \ + \ 2W^2}{W}[/tex]
Thus, the perimeter of the rectangle is expressed as [tex]P = \frac{72 \ + \ 2W^2}{W}[/tex]

What is equation?An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, it can be said as of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
Mark spent a total of $16.35 to buy a total of 11 bags of carrots and bags of tomatoes.
Each bag of carrots costs $1.05, and each bag of tomatoes costs $1.65.
let, he bought x bags of carrots and y bags of tomatoes.
now, we get,
x+y = 11 ....(1)
1.05x + 1.65y = 16.35 ....(2)
solving this, we get,
x= 3
y= 8
Hence, The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.

The ratio of my age 12 years ago to my age now is 2/3. How old will I be in 5 years?
Answer:
41 years old
Step-by-step explanation:
n = age now
create proportion, then cross-multiply:
(n-12)/n = 2/3
2n = 3n-36
-n = -36
n = 36
in 5 years age will be 36+5 or 41

solve the equation 4 x - 6 = 6- 2x
Answer:
x=2
Step-by-step explanation:
4x-6=6-2x
(add 2x and 6 to both sides)
6x=12
(divide by six)
x=2
Double Check:
4(2)-6=2
6-2(2)=2
4(2)-6=6-2(2)
Answer:
x=2
Step-by-step explanation:
4x-6=6-2x
move the variables to right and constants to the left
4x+2x=6+6
combine like terms
6x=12
isolate x by dividing by 6 on both sides to find it's value
x=2

what is the rate of change for y=5.6x+7
Answer:
5.6
Step-by-step explanation:
The equation is put in y = mx + b
where m = slope ( rate of change ) and b = y intercept
5.6 = m and 7 = b
Hence the rate of change for y = 5.6x + 7 is 5.6

Answer:
-38
Step-by-step explanation:
-38 - 7 = -45
-45 divided by 9 = -5
Answer: y = -38
The value of y is -38
Step-by-step explanation:
First, you want to multiply all terms by the same value to eliminate fraction denominators:
-5 = (y-7) / (9)
9(-5) = 9 * (y - 7) / (9)
Then you will cancel multiplied terms that are in the denominator:
9(-5) = 9 * (y - 7) / (9)
9(-5) = y - 7
Then multiply the numbers:
9(-5) = y - 7
-45 = y - 7
Solve and simplify:
y = -38
Solution:
y = -38
