The ratio of liters to gallons in simplest form is 5 : 19.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, 1 gallon is around 3.8 liters.
So, The ratio of liters to gallons in a : b form is 1 : 3.8

Explanation: 148 and C is an opposite angle so the angles oppose to it has the same value
D) h = 76
Explanation: opposite angles
I = 76
Explanation: transverse angles

please help with the following maths question
Answer:
120 degrees
Step-by-step explanation:
Regular hexagon means all the sides are equal
(6-2)(180)=The sum of interior angles of hexagon
=>720 degree
Therefore each angle=720/number of sides
=720/6=120 degree
So let the marked angle in figure be 'x'
And the adjacent equal angles to x, y
So y+y+x=360 [Angle around point=360]
2y+x=360 [but y=120 degree proved]
240+x=360
x=120
Answer:
the answer is 120 degrees- i dont feel like typing everything out about how i got it but ik thats the answer.

Solve the equation 3x-7=x+23
Answer:
x = 15
Step-by-step explanation:
3x-7=x+23
Subtract x from each side
3x-x-7=x-x+23
2x -7 = 23
Add 7 to each side
2x-7+7 = 23+7
2x = 30
Divide by 2
2x/2 = 30/2
x = 15
Answer:
x=15
Step-by-step explanation:
3x-x=23+7
2x=30 divide by 2
x=15
You have 20 gallons of roof coating to apply to the roof of a mobile home that is 16 feet wide. Twenty gallons covers 760 to 1000 square feet. Find the interval for the length of x that you will cover before you need to buy more roof coating.
Area = length x width.
Divide the two total areas by the width to find the lengths:
760/16 = 47.5
1000/16 = 62.5
The interval is:
47.5<= x <= 6.5
The interval for the length of x that you will cover before you need to buy more roof coating will be 47.5 ≤ x ≤ 6.5.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.The space occupied by any two-dimensional figure in a plane is called the area.

What is Function?A relation between a set of inputs having one output each is called a function.
Given that;
The function is,
⇒ f (x) = x² - 10x + 22
Now, We know that;
Domain of a function is defined as a set of value for which the value of function is real and defined.
Here, There is no points for x where the function f(x) is non defined.
Hence, Whole number line is the domain for the given function.

Joe is making key chains with beads. He wants each key chain to have the same number of beads. He has 90 blue beads and 72 yellow beads. What is the highest amount of key chains he can make?
Answer:1.25
Step-by-step explanation:90/72
Joe can make 9 key chains to have the same number of beads with 90 blue beads and 72 yellow beads.
What are HCF and distributive property?The HCF of two or more than two numbers is the highest number that divides the given two numbers completely.
Joe wants each key chain to have the same number of beads.
∴ HCF of 72 and 90 is 18
Now with those 18 beads 9 each type he can make (90 + 72)/18 key chains.
= 162/18.

i need help finding out the pattern of 3 and 4
Answer:
See below.
Step-by-step explanation:
For 3, we have:
1, 3, 6, ___, 15, 21, _____, 36, _______
Let's try to determine the pattern. From 1 to 3, we added 2.
From 3 to 6, we added 3.
So, it seems that the fourth term would be to add 4, and then add 5. Let's try it:
6+4=10
10+5=15.
So, it seems we're correct. So, we will add 6, then 7, and then 8, etc. Therefore, our correct sequence would be:
1 (+2), 3 (+3), 6 (+4), 10 (+5), 15 (+6), 21 (+7), 28 (+8), 36 (+9), 45
For 4, we have:
100, _____, 64, ______, 36, 25, _______
Notice that these all are perfect squares. 10 squared is 100, 8 squared is 64, etc. Thus, we can rewrite this as:
10², _____, 8², ______, 6², 5², ______
Therefore, our blanks would be:
10², 9², 8², 7², 6², 5², 4².
Evaluated, this woul be:
100, 81, 64, 49, 36, 25, 16.

Multiply (6 − 7i)(3 − 6i).
Answer:
-24 - 57i
Step-by-step explanation:
i'm assuming that this is a question about imaginary numbers and that i²= -1
we can expand the binomial by using the FOIL method (see attached)
(6 − 7i)(3 − 6i)
= (6)(3) + (6)(-6i) + (-7i)(3) + (-7i)(-6i)
=18 - 36i - 21i + 42i² (recall that i²= -1)
= 18 - 57i + 42(-1)
= 18 - 57i - 42
= -24 - 57i
If the square root of a number is equal to twice the same number what is the number?
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
let the number be x , then
[tex]\sqrt{x}[/tex] = 2x ( square both sides )
x = (2x)² = 4x² ( subtract x from both sides )
4x² - x = 0 ( factor out x from each term )
x(4x - 1) = 0
Equate each factor to zero and solve for x
x = 0
4x - 1 = 0 ⇒ 4x = 1 ⇒ x = [tex]\frac{1}{4}[/tex]
Assuming x > 0 then the number is [tex]\frac{1}{4}[/tex]
As a check
[tex]\sqrt{\frac{1}{4} }[/tex] = [tex]\frac{1}{2}[/tex] and 2 × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{2}[/tex]
