Clint completly filled his 18 gallon tank of gas with regular fuel for 55.08. As he left the gas station he noticed the station arcross the street sold regular fuel for 2. 99 Per gallon how much money could have clint saved per gallon is he had gone to the station across the street
Answer: 1.26
Step-by-step explanation:
Since he bought a 18 gallon tank of gas with regular fuel for 55.08.
The station across the street sold regular fuel for 2.99 per gallon. A 18 gallon tank will cost:
= 18 × 2.99
= 53.82
The amount that could have been saved would be:
= 55.08 - 53.82
= 1.26

Pierre had $42 before he paid his club dues. Evaluate the expression 42 − d for d = 25 to find how much money Pierre had left after he spent $25 on dues.
Answer:
$17
Step-by-step explanation:
This is simply stated as a function.
We can rewrite this problem out as --> f(d) = -d + 42
If we simply say that he spent d, the problem states that d is equivalent to 25.
So the function looks like this --> f(d) = -25 + 42
Therefore your answer becomes --> f(d) = 17
What is the product of d – 9 and 2d2 + 11d – 4?
2d3 – 7d2 – 103d + 36

What is the length of the altitude of the equilateral triangle below?
Answer:
Step-by-step explanation:
It would be helpful if you could share the diagram of the equilateral triangle.
All 3 sides are equal, as are all 3 angles.
The altitude is perpendicular to the base. The altitude, h, is equal to
h = s*( (√3) / 2, where s is the length of one side of the triangle.

The equation a= 13 25p models the relationship between the pounds of topsoil and the area covered in square feet. Determine the pounds of topsoil Caleb needs to order to cover an area of 169one hundred sixty nine square feet.
Answer:
Pounds of topsoil needs to order to cover an area of 169 square feet is 0.1275
Step-by-step explanation:
GIVEN: relation between the pounds of topsoil and area covered is ( a = 1325 p )
a represent area and b represent pounds of topsoil
To Find : pounds of topsoil needs to order to cover given area .
Solution : since here relation is given
a = 1325 p
value of a = 169 square feet
so putting the value of a in above relation
so , 169 = 1325 p
p = 169 / 1325 = 0.1275
So , pounds of topsoil needs to order to cover given area is 0.1275
Answer:
0.1275

1. Water vapor given off by water, plants, and animals is called ?
A. evaporation
B. precipitation
C. condensation
D. runoff
Answer:
evaportation
Step-by-step explanation:
The vapor given off by water, plants, and animals is called evaporation.
What is evaporation?Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water.Given is to find what does the water vapor given off by water, plants, and animals is called.
Evaporation is defined as the conversion of water into water vapour (into gas phase) and its release into the atmosphere. Similarly, the Water vapor given off by water, plants, and animals is called evaporation.
Therefore, the vapor given off by water, plants, and animals is called evaporation.

Answer:
2 c ( 7c + 1 )
Step-by-step explanation:
because 14 and 2 go into the table of 2
you first find out what number in table 2 go into 14 in this case 7 times 2 and then you find what number in the time table 2 give you 2 so it's 2 times 1. because it's c squared you can't not put both c inside due that would not be factorizing due that it's common and it does not have to be common.
so the answer will be 2c(7c+1)

The domain values of a rational function are not only restricted to the only set of all real numbers making the given statement false
The domain of a function is the input values of the function for which it exists.
Rational functions are function that can be written as a ratio of two functions. For example given the function f(x) = 2/x-3
The domain values are the input values x. The values of x can be any values either real numbers, integers, or even natural numbers.
This means that the domain values of a rational function are not only restricted to the only set of all real numbers making the given statement false

Solve by the substitution method. 8x + 9y=56 -9x + y = 26
Answer:
(-2,8)
Step-by-step explanation:
8x + 9y=56
-9x + y = 26
---------------------------------------------------------------------------------
-9x + y = 26
+9x = +9x
y = 9x + 26
---------------------------------------------------------------------------------
8x + 9(9x+26) = 56 <-- substitute for y from above
8x + 81x + 234 = 56
89x + 234 = 56
- 234 = - 234
89x = - 178
x = -2 <--- we got the x value!!
--------------------------------------------------------------------------------
-9x + y = 26
-9 (-2) + y = 26 <-- substitute for x from above
18 + y = 26
- 18 = - 18
y = 8 <-- we got the y value!!

What is the value of x in the equation 25x2 = 16. A. 5/4. B. 4. C. 4/5. D. 16/25
Answer:
x = ⅘
Step-by-step explanation:
For clarity, exponents should be marked with a ^. 25x² can be written as 25x^2.
25x² = 16
divide both sides by the 25
x² = 16/25
take the square root of both sides
x = √(16/25) = √16/√25 = 4/5
