Answer:
Gallons Miles
2 56
4 a
b 168
10 c
To Find : the missing values a , b , c and constant of proportionality
Solution:
constant of proportionality of x miles per gallon
=> Miles = x * gallons
Gallons = 2
=> Mile s= 2 * x = 56
=> x = 28
Gallons = 4
=> Mile s= 4 * 28 = 112 = a
Gallons = b
=> Mile s= b * 28 = 168
=> b = 7
Gallons = 10
=> Mile s= 10 * 28 = 280 = c
Gallons Miles
2 56
4 a =112
b=7 168
10 c=280
constant of proportionality = 28
a = 112
b = 7

Luis's cell phone plan costs $39 per month. Text messages cost an additional $0.15 each. If Luis's cell phone bill last month totaled $55.05
Answers
Answer:
Luis incurred 107 extra text messages.
Step-by-step explanation:
Giving the following information:
Luis's cell phone plan costs $39 per month. Text messages cost an additional $0.15 each.
To calculate the number of text messages, we need to use the following formula:
Total cost= 39 + 0.15x
x= number of text messages
55.05= 39 + 0.15x
16.05= 0.15x
107= x
Luis incurred 107 extra text messages.
The seventh and tenth terms of a geometric sequence are 7 and 21 respectively. What is the 13th term of this progression?
Answers
Answer:
63
Step-by-step explanation:
Each term in a geometric sequence progresses by multiplying a constant (let us name it r).
Let us solve for this constant r in order to find the 13th term.
If the seventh term is 7, the tenth term would be 7*r*r*r, or [tex]7r^{3}[/tex]. We also happen to know that the 10th term is 21. Let us make a new equation:
[tex]7r^{3} =21\\r^{3}=3\\r= \sqrt[3]{3}[/tex]
or, approx. 1.442249570307408
Using the same logic, the 13th term would be 7*r*r*r*r*r*r, or [tex]7r^{6}[/tex]. We may now substitute what we know, r, into this expression to obtain the 13th term:
[tex]7*\sqrt[3]{3}^{6} = \\7*3^{2}=\\7*9=\\63[/tex]
Therefore, the 13th term of this progression is 63.

There are 40 litres of water in a barrel.
The water flows out of the barrel at a rate of 125 millilitres per second.
1 litre = 1000 millilitres.
Work out the time it takes for the barrel to empty completely.

It would take 320 seconds or 5 minutes 20 seconds.
Hope this helps! Any questions let me know :)
The time it takes for the barrel to empty completely will be 5 minutes and 20 seconds.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
There are 40 liters of water in a barrel. The water streams out of the barrel at a pace of 125 milliliters each second. 1 liter = 1000 milliliters.
Convert the 125 milliliters each second into liters per minute.
⇒ (125) x (60 / 1000)
⇒ 7.5 liters per minute
The number of minutes for the barrel to empty completely will be given as,
⇒ 40 / 7.5
⇒ 5.3333 minutes
⇒ 5 + 0.3333 x 60
⇒ 5 minutes 20 seconds
The time it takes for the barrel to empty completely will be 5 minutes and 20 seconds.

how do i calculate the lateral surface area of a cube the length,width,and hieght are all 4
Answers
I don't know if I am correct or not, but I believe that you have to multiply the perimeter of your base and then multiply that by the height of your cube.
So in this case, you would do 4 x 4, since a cube is basically 6 squares, and a square has 4 sides.
4 x 4 = 16
Then the height is 4 as well.
16 x 4 = 64² (I believe you have to square the total as well, so don't forget that.)
If I am incorrect, please let me know. But I really do hope this helped. :)

so let that equal angles be 2x, so one of them is x
therefore, by angle sum property
146 + x + x = 180
146 + 2x = 180
2x = 180 - 146
x = 34/2
x = 17degree

solve for x
1 2/3 divided by x = 2 7/9
Answers
1 2/3 = 5/3
2 7/9 = 25/9
5/3 ÷ x = 25/9
5/3 = (25/9)x
Multiply both sides by 9/25
5/3 * 9/25 = x
x = (5*9)/(3*25) = 3/5
The solution to the given equation (1 2/3) ÷ x = (2 7/9) is x = 15/16.
To solve the equation (1 2/3) ÷ x = (2 7/9), we need to isolate the variable x.
First, let's convert the mixed numbers to improper fractions:
1 2/3 = (3/3 + 2/3) = 5/3
2 7/9 = (9/9 + 7/9) = 16/9
The equation becomes (5/3) ÷ x = (16/9).
To eliminate the fraction in the numerator, we can multiply both sides of the equation by the reciprocal of (5/3), which is (3/5):
[(5/3) ÷ x] × (3/5) = (16/9) × (3/5)
Simplifying, we get:
1 ÷ x = 48/45
To isolate x, we can take the reciprocal of both sides of the equation:
x ÷ 1 = 45/48
Simplifying to get:
x = 45/48
Therefore, the solution to the equation is x = 15/16.
