Bonnie filled her car's gas tank. She put in 10 1/2 gallons and paid $15.36. Write the ratio in fractional form and determine the cost of gasoline per gallon
Answer:
1: 2 and $3.072
Step-by-step explanation:
According to the question, the data provided is as follows
10 half gallons
For this she paid $15.36
Based on the above information,
The ratio in fractional form is
= 1 ÷ 2
= 1 : 2
And, the cost of gasoline per gallon is
Since half of 10 gallons is 5
And, the amount paid is $15.36
So, the cost of gasoline per gallon is
= $15.36 ÷ 5
= $3.072

Solve for b.
y = mx + b
Answer:
b = y - mx
Step-by-step explanation:
So we are trying to solve for b in the equation y = mx + b. To do this, we will have to somehow get the b by itself on one side and all of the non-b parts of the equation on the other side.
y = mx + b
Subtract mx from both sides.
y - mx = b
b = y - mx
So we have not solved for b. We have found that b = y - mx.
I hope you find my answer and explanation helpful. Happy studying. :)
Dimensions of a Box A large plywood box has a volume of . Its length is ft greater than its height, and its width is ft less than its height. What are the dimensions of the box
Answer:
Few things are missing, they are volume of the box is 180 feet cube. Length is 9 feet greater than its height, and weight is 4 feet less than its height.
Step-by-step explanation:
Given, the volume of the box, V = 180 feet cube
Let the height of the box, h = x feet
Therefore, length is, l = ( 9+x ) feet
And width is, b = ( x-4) feet
so volume of the box is
V = l x b x h
[tex]$ 180= (x+9) \times (x-4) \times (x)$[/tex]
[tex]$ x^3 +5x^2-36x -180 =0$[/tex]
Factorizing we get
(x+5)(x-6)(x+6)=0
Therefore,
x = -5, -6, 6
Now since the height of the box cannot be negative, so taking the positive value of x, we get
Height of the box, h = x = 6 feet
Length , l = ( 9+x ) = 9+6 = 15 feet
Width , b = ( x-4) = 6-4 = 2 feet
Rewrite the equation below using ONLY the symmetric property of equality:2x + 5 = 3x -7
Answer:
12 = x
Step-by-step explanation:
Symmetry here would involve subtracting the same quantity from both sides of the equation.
Starting with 2x + 5 = 3x -7,
subtract 2x from both sides. This yields
5 = x - 7
Adding 7 to both sides yields
12 = x

find the dimension of the missing side of a triangle given the following measurements: A=75 sq. ft, b=15 ft, h=?
Answer:
h = 10 ft
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh
Here A = 75 and b = 15, thus
[tex]\frac{1}{2}[/tex] × 15h = 75 ( multiply both sides by 2 to clear the fraction )
15h = 150 ( divide both sides by 15 )
h = 10

what describes the first factor in scientific notation
Answer:
mantissa
Step-by-step explanation:
The word "mantissa" is used to describe the portion of the number that represents the significant digits in scientific notation.
__
The term also refers to the fractional portion of a logarithm. Of course, that fractional portion also represents the significant digits of the number. The integer portion of the logarithm is the power of 10 that multiplies the significant digits.
7. Find the value of:
a) The number when 40% of the number is 10
Step 1) Set up a proportion
Proportion: percent / 100 = x / number
In context of the problem, the proportion is: 40 / 100 = 10 / number
Step 2) Cross-multiply and solve
100 x 10 = 40 x N
1000 = 40N
N = 25
Answer: The number is 25
Answer:
25Step-by-step explanation:
Let the unknown number be x
[tex]40 \% \times x = 10 \\ \frac{40x}{100} = \frac{10}{1} [/tex]
Cross Multiply
[tex]40x = 100 \times 10 \\ 40x = 1000[/tex]
Divide both sides of the equation by 40
[tex] \frac{40x}{40} = \frac{1000}{40} [/tex]
Simplify

On January 22, 1945, the temperature in Spearfish, South Dakota, fell from 54 degrees Fahrenheit at 9 am to -4 degrees at 9:27 am. how many degrees did it fall?
Answer:
58
Step-by-step explanation:
Use a number line.
-4 + 4 = 0.
So, you already have 4 Fahrenheit.
Then, add the distance of 54 from 0 to 54.
4 + 54 = 58.
That is your answer, here to help!
The distance an object travels is determined by how fast it goes and for how long it moves. If an object’s speed remains constant, the formula is d=r*t , where d is the distance, r is the speed, and t is the time. If you drive at 50 miles per hour for 5 hours, how far will you have traveled? a. 200 miles b. 10 miles c. 250 miles d. 300 miles Please select the best answer from the choices provided A B C D
Answer:
d = r * t
r = 50 mph
this will be very easy.
d = r * t
r = 50 mph
t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.

Which of the following statements must be TRUE by construction? Select all that apply.
A
AB and an have the
Answer:
The correct options are;
B. AC and AD have the same length
D. Triangle BCE is isosceles
Step-by-step explanation:
From the diagram we have;
B. Segment AC and segment CD are the radii of the same circle with center C and radius AC, therefore, given that the radius of a circle is constant round a circle, we have;
The length of AC = The length of AD
D. In triangle BCE, we have the length of segment CB is equal to the length of segment CE which are both radii of the circle with center C and radius CE, therefore, the triangle BCE has two sides equal which gives triangle BCE is an isosceles, from the definition of isosceles.
The length of the rectangle below is (2x-3) and the width is (x+7). Find the area of the rectangle in terms of x.
Answer:
area = 2x² - 17x - 21
Step-by-step explanation:
Area of the rectangle is:
area = (width*length)
area = (x+7)*(2x-3)
= x*2x + x*-3 + 7*2x + 7*-3
= 2x² - 3x - 14x - 21
= 2x² - 17x - 21
The area of the rectangle in terms of x should be [tex]2x^2 + 11x - 21[/tex]
Given that,
Length is 2x - 3.Width is x + 7.We need to determine the area of the rectangle
As we know that
The area of the rectangle be
[tex]= length \times breadth\\\\= (2x - 3) (x + 7)\\\\= 2x^2 +14x - 3x - 21\\\\= 2x^2 + 11x - 21[/tex]
Therefore we can conclude that The area of the rectangle in terms of x should be [tex]2x^2 + 11x - 21[/tex]

Which domain window settings would be appropriate if you wanted to graph the function below in radians for exactly
two periods?
f(x) = cos(x)
Xmin = 0 Xmax = 720
O Xmin = 0 Xmax = 2pi
O Xmin = -180 Xmax = 180
O Xmin = - Xmax = 3pi
Answer:
Xmin = –π Xmax = 3π
Step-by-step explanation:
Domain window settings Xmin = 0 & Xmax = 720° would be appropriate if you want to graph the function for exactly two periods.
What is the period of a function?The distance between the repetition of any function is called the period of the function.
For example, for the cosine function, the distance between the repetition of the function is [tex]2\pi[/tex]. So the period of the cosine function is [tex]2\pi[/tex].
If you want to graph the function for exactly two periods the difference between the first and last element of the domain should be two times the period of the function.
i.e. If the domain is [a, b] the value of [tex]b-a = 4\pi[/tex].
Option(1) b-a =720° [tex]=4\pi[/tex]
Option(2) b-a =[tex]2\pi[/tex] [tex]\neq 4\pi[/tex]
Option(3) b-a =360 [tex]\neq 4\pi[/tex]
Option(4) b-a =[tex]3\pi[/tex][tex]\neq 4\pi[/tex]
So, correct option is option(1) i.e. Xmin = 0 & Xmax = 720°
Hence, domain window settings Xmin = 0 & Xmax = 720° would be appropriate if you want to graph the function for exactly two periods.
