If j // l, m<1 = 135, m<2 = 55, and m<3 = 45, list all other parallel lines. Justify your answers. Show work if any.
Answer:
Step-by-step explanation:
The supplement to ∠1 = 180°-135° = 45° = ∠3, so m is parallel to j and l.
∠2 ≠ 45° and ∠2 ≠ 135°, so k is not parallel to j, l, or m.
How many 1/2 cup servings are in 4 cups of ice cream?
Answer:
8 1/2 cup servings
Step-by-step explanation:
Hello!
Well to solve this we have to take the total amount of cups of ice cream and divide it amongst the servings.
So :
Total = 4 cups
Serving = 1/2 cup
What we can do since its such a lower number is count it out by increments of 1/2.
Like so :
1/2 1 1 1/2 2 2 1/2 3 3 1/2 4So, in total, there would be 8 servings of half a cup of ice cream in 4 cups.
I hope this helps!
If you have any questions or concerns feel free to message me or comment! :)
The number of 1/2 cup servings are in 4 cups of ice cream are 8.
What is Division?A division is a process of splitting a specific amount into equal parts.
We need to find the number of 1/2 cup servings are in 4 cups of ice cream
A half cup serving is equal to 4 fluid ounces.
Therefore, 4 cups of ice cream is equal to 8 half-cup servings,
since 4 cups is equal to 32 fluid ounces and 32 divided by 4 equals 8.
4/(1/2)
4×2
8 cups
Hence, the number of 1/2 cup servings are in 4 cups of ice cream are 8.

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure.
a tree grows a ring for each year, therefore, to determine a trees age, you need to count the rings. the rings "r" dictate the age or years "y"

If the area of a square with side x is equal to the area of a triangle with base x, then find the altitude of the triangle.

Step-by-step explanation:
Given
Square
[tex]Side = x[/tex]
Triangle
[tex]Base = x[/tex]
[tex]Altitude = h[/tex]
Required
Find h, if both shapes have the same area
The area of the square is:
[tex]Area = x * x[/tex]
[tex]Area = x^2[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} * Base*Height[/tex]
[tex]Area = \frac{1}{2} * x*h[/tex]
Equate both areas
[tex]x^2 = \frac{1}{2} * x*h[/tex]
Divide both sides by x
[tex]x = \frac{1}{2} *h[/tex]
Multiply both sides by 2
[tex]2*x = \frac{1}{2} *h*2[/tex]

7 Eva has 4 m of ribbon for wrapping gifts.
She needsm for each gift.
How many gifts can Eva wrap?
Answer: 6 gifts.
Step-by-step explanation:
I found the question elsewhere and it states that Eve needs 2/3 m for each gift.
Since Eve has 4 m, the number of gifts she can wrap is the 4 m she has divided by the 2/3 m required for each gift.
= 4 ÷ 2/3
= 4 × 3/2
= 12/2
= 6 gifts.
Note: When dividing by a fraction, you can multiply by it's inverse.

Answer:
D
Step-by-step explanation:
We can safely assume we are dealing with an arithmetic scale because the type of scale isn't mentioned anywhere. The more right a point is on the scale, the higher its value is. We are given two points of the scale: 3 and 4. Because the scale is arithmetic, we know that 3.8 must lie on 4/5s of the length between 3 and 4 to the right of 3, which is exactly where point D is.
x - 2y = 8
3x = 19 + 4y
how to answer this through elimination or substitution method?
Answer:
The solution of the given equations
x = 3 and y =-2.5
Step-by-step explanation:
Step(i):-
x - 2y = 8 ..(i)
3x = 19 +4y ..(ii)
By using substitution method
substituting x = 2y +8 in equation (ii)
⇒ 3( 2y +8) = 19 +4y
⇒ 6y +24 = 19 +4y
⇒ 6 y - 4y = 19 - 24
⇒ 2 y = -5
[tex]y = \frac{-5}{2} = -2.5[/tex]
Step(ii):-
Substitute 'y' = -2.5 in equation (i) , we get
x - 2y = 8
⇒ x - 2( [tex]\frac{-5}{2}[/tex]) =8
⇒ x = 8 -5
x = 3
Final answer:-
The solution of the given equations
x = 3 and y =-2.5
Which is a reasonable domain for the function f(x)=10x+8
Answer:
(-∞,∞)
Step-by-step explanation:
The domain is all possible x values of the function
There are no constraints or holes for this and therefore the domain is all real numbers
A function is a relationship between inputs where each input is related to exactly one output.
x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........
The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 10x + 8
We can have any real values of x.
f(-2) = -20 + 8 = -12
f(-1) = -10 + 8 = -2
f(1) = 10 + 8 = 18
f(2) = 20 + 8 = 28
f(3) = 30 + 8 = 28
.
.
.
x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........
So,
The domain of the function f(x) = 10x + 8 is -∞ to ∞.
We can write as an interval as,
(-∞, ∞).
Thus,
The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).

A quantity b varies jointly with c and d and inversely with f. When c is 4, d is 9, and f is 6, b is 18. What is the constant of variation?
Answer:
k = 3
Step-by-step explanation:
Given that b varies jointly with c and d and inversely with f then the equation relating them is
b = [tex]\frac{kcd}{f}[/tex] ← k is the constant of variation
To find k use the condition c = 4, d = 9, f = 6 , b = 18, then
18 = [tex]\frac{k(4)(9)}{6}[/tex] = [tex]\frac{36k}{6}[/tex] = 6k ( divide both sides by 6 )
