Find the slope of a road that rises 12 feet for every horizontal change of 100 feet.
Answers
The answer should be 0.12 because you have to do rise over run to get slope. So, 12 divided by 100 gets you 0.12.

b. The equation has no solution
What are properties of exponents?a. Properties of exponents are mathematical rules that allow us to simplify and manipulate expressions involving exponents. These properties help us perform operations such as multiplication, division, and raising to a power more efficiently.
In the given problem, we have to solve and simplify using properties of exponents.
Given that; [tex]\frac{10^-^3}{10^-^3}[/tex];
we can apply quotient rule when dividing exponents here;
[tex]\frac{10^-^3}{10^-^3} = 10^-^3 ^+^3 = 10^0[/tex]
The answer is 10⁰
b. To simply the equation, we just need to use basic mathematical operation to find the value of x.
3x - 2x + 4 = 5x - 4x - 8
Simplify;
x + 4 = x - 8

What is 3 1/3 +(-2 1/4) + 1 5/6 as a mixed fraction

By separating between whole numbers and fractions, we will see that the sum is equal to 2 + 11/12.
How to add mixed numbers?
Here we want to perform the sum:
(3 + 1/3) + (-2 - 1/4) + (1 + 5/6)
We separate between whole and fractions, so we get:
(3 - 2 + 1) + (1/3 - 1/4 + 5/6)
The left part is easy: 3 - 2 + 1 = 2
The right part needs to find a common denominator, we will use 12.
1/3 - 1/4 + 5/6 = 4/12 - 3/12 + 10/12 = 11/12
Then the sum is:
(3 + 1/3) + (-2 - 1/4) + (1 + 5/6) = 2 + 11/12

find two consecutive odd integers such that 36 more than the lesser is three times the greater
Answers
x= first integer
x+2= second integer
x + 36= 3(x + 2)
multiply 3 by everything in parentheses
x + 36= 3x + 6
subtract x from both sides
36= 2x + 6
subtract 6 from both sides
30= 2x
divide both sides by 2
15= x
x= 15 first consecutive odd integer
x+2= second consecutive odd integer
15+2= 17
ANSWER: 15, 17
Hope this helps! :)
Final answer:
To find two consecutive odd integers such that 36 more than the lesser is three times the greater, set up an equation and solve for the variable x. The two consecutive odd integers are 15 and 17.
Explanation:
To find two consecutive odd integers such that 36 more than the lesser is three times the greater, we can set up an equation:
x + 36 = 3(x + 2)
Simplifying this equation, we get:
x + 36 = 3x + 6
Subtracting x from both sides, we get:
36 = 2x + 6
Subtracting 6 from both sides, we get:
30 = 2x
Dividing both sides by 2, we get:
15 = x
Therefore, the two consecutive odd integers are 15 and 17.

The scatter plot below shows the number of pizzas sold during weeks when different numbers of coupons were issued. The equation represents the linear model for this data. y = 3.4x + 43
According to the model, what is the average number of pizzas sold in one night if no coupons are issued?
Question 5 options:
A 43
B 0
C 11
D 21
Answers
Answer:
option: A is correct.
Step-by-step explanation:
We are asked to find the average number of pizzas sold in one night if no coupons are issued.
i.e. we have to find the value of y such that x=0 i.e. no coupon was issued.
We are given a equation which represents the linear model for this data:
y = 3.4x + 43
where y denotes the average number of pizza sold and x denotes the number of coupons issued.
Hence when x=0 we have value of y from the above linear equation as:
y=3.4×0+43=0+43=43
i.e. y=43.
Hence, average number of pizzas sold in one night if no coupons are issued are 43.

y = A * (b) ^ t
Where:
A: initial population.
b: growth rate.
t: time.
Substituting values we have:

y = 15200 * (1.02) ^ 10
y = 18529

o decorate his bedroom, Mike spent $41.64 on new bedding, $36.84 on paint, and $72.49 on accessories. About how much did he spend to decorate his bedroom?
Answers
Answer:
Mike spent $150 on his decorations.
Step-by-step explanation:
In order to find the amount of money Mike spent on his decorations you must add all the costs together.
$41.64 + $36.84= $78.48
$78.48 + $72.49= $150.97
Then you round 150.97 to 151, which is also close to 150.

Answer:
f(x) = 2(x-11)^2 - 57
Step-by-step explanation:
To write f(x) = 2x^2 – 44x + 185, factor out from the first two terms.
Next, form a perfect square tri nomial keeping the value of the function equivalent: f(x) = 2(x^2 – 22x + 121) + 185 – 242
To get vertex form we factor x^2 -22x+121
product is 121 and sum is -22
-11*-11= 121 and sum -11+(-11)= -22
x^2 -22x+121
(x-11)(x-11)
f(x) = 2(x^2 – 22x + 121) + 185 – 242
f(x) = 2(x-11)(x-11)+ 185 – 242
f(x) = 2(x-11)^2 - 57
