Lena knit a total of 20 centimeters of scarfs over night. How many nights will Lena have to spend knitting in order to knit a total of 50 cm of scarfs. Assume the relationship is directly proportional.
Answer:
50cm of scarfs is equal to 2.5 nights of knitting.
Step-by-step explanation:
20cm= 1 night
10cm= 1/2 or 0.5 a night
40cm= 2 nights
50cm=2.5 nights
Is 16x2 - 16x + 4 a perfect square?
Answer:
Yes
Step-by-step explanation:
Use the completing the square method:
16(x^2-x)+4
=16((x-1/2)^2 - (1/2)^2)+4
=16((x-1/2)^2 - 1/4)+4
=16((x-1/2)^2) - 16/4 + 4
=16(x-1/2)^2
=4^2(x-1/2)^2
The product of two square is itself a square.

Look at the ingredients needed to make Josie's special pancakes. How much pancake mix and milk will you need if you want to double the recipe? to triple the recipe? solve this problem anyway you choose math answer
Answer:
Double - 7 5/6
Explantion: 2 1/4 times 2 equal 4 1/2 for the pancake mix
1 2/3 times 2 equal 3 1/3 for the milk
So.....4 1/2 plus 3 1/3 equals 7 5/6
Triple- 11 3/4
Explantion: 2 1/4 times 3 equals 6 3/4 for the pancake mix
1 2/3 times 3 for the milk equals 5
So.... 5 plus 6 3/4 equal 11 3/4

If a solution to a linear system of equations is no solution, then what must be true about the graph of the system?
Answer:
Step-by-step explanation:
The lines are parallel to one another.
A linear system of equations has no solution if the graphs are parallel and the two lines never meet.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
There can be one solution to a system of two linear equations, an infinite number of solutions, or no solutions at all. The number of solutions to a system of equations can be used to categorize it.
A system is deemed consistent if there is at least one solution to the problem. A consistent system is said to be independent if it only has one possible outcome.
Thus, a linear system of equations has no solution if the graphs are parallel and the two lines never meet.

Answer:
arc 1 = 108 degrees
angle 2 = 54 degrees
Step-by-step explanation:
180 - 72 = 108 (half circle -72)
draw a line from center of circle to tangent point.
this line is perpendicular to the tangent line.
all radii are equal.
then, triangle made with the new line is isosceles with two equal angles.
those angles are 36 degrees each (180 - 108 = 72, 72/2 = 36)
line drawn from center to tangent point is 90 degrees so:
90 - 36 = 54 degrees

Which letter represents 1/8 on the following number line ?
Answer:
the answer is p
Step-by-step explanation:
Write an equation in slope-intercept form of the line that passes through the given points. 0,4 4,2
First, find the slope: m = Δy/Δx = (2-4)/(4-0) = -0.5
The "intercept" in the slope-intercept form of a line is the y-intercept. And at the y-intercept, x = 0. Conveniently, one of our points has an x = 0, i.e., the point (0,4). So, our equation would be y = -0.5x + 4.
If you wanted to double-check, you could use the point (4,2) to find the point-slope equation of the line and see if it matches up with the slope-intercept form above. Given a slope of -0.5 and a point (4,2), our point-slope equation would be y - 2 = -0.5(x - 4). If we expand this, we get y - 2 = -0.5x + 2. Solving for y, we obtain y = -0.5x + 4.
Thus, y = -0.5x + 4 would be our equation.
hello, can i please have help on this question.thank you
Answer:
y = 4x - 3
Step-by-step explanation:
The equation for a line is y = mx +c
We need to find m which is the gradient:
To do this pick any two coordinates on the line:
(1, 1) and (2, 5)
Next divide the difference of the y coordinates by the difference of the x coordinates:
5 - 1 / 2 - 1
= 4/1 = 4
so our gradient is 4
We'd write that as y = 4x + c
Next we need to find c which is the y-intercept
To do this just simply look for where the line crosses the y-axis
This is -3
So we'd write that as y = 4x - 3
Hope this helps :)

Determine how many feet each member of Lola's family walked.
Lola's pet turtle walked 10 feet, and then half that length again.
Lola's baby brother walked 3 feet, and then half that length again.
Lola's hamster walked 6.5 feet, and then half that length again.
Lola's mom walked x feet, and then half that length again.
Step-by-step explanation:
Lola's pet turtle walked 10 feet, and then half that length again. This means that Lola's pet turtle walked:
= 10 + (1/2 × 10) = 10 + 5 = 15 feet
Lola's baby brother walked 3 feet, and then half that length again. Total length walked will be:
= 3 + (1/2 × 3) = 3 + 1.5 = 4.5 feet
Lola's hamster walked 6.5 feet, and then half that length again. Total length walked will be:
= 6.5 + (1/2 × 6.5) = 6.5 + 3.25 = 9.75
Lola's mom walked x feet, and then half that length again. Total length walked will be:
= x + (1/2 × x) = x + 0.5x = 1.5x
Total feet walked by the whole member of the family will be:
= 15 + 4.5 + 9.75 + 1.5x
= 29.25 + 1.5x
Answer:
turtle: 10 + 5 = 15
brother: 3 + 1 1/2 = 4 1/2
hamster: 6 1/2 + 3 1/4 = 9 3/4

Answer:
Step-by-step explanation:
Im going to assume they want x+108.
You have 2 expressions sitting on a line, so when added to each other they must = 180
So add and set up an equality
x+108+x+78=180
Combine like terms
2x+186=180
Solve
2x+186=180
-180 -180
2x+6=0
-6 -6
2x=-6
________

x=-3
Substitute X for -3
