Answer:
162 cents
Step-by-step explanation:
to find the rate you want take the inches which is 21 and divide by the cost which is 63 and find the rate is 3 which means each inch costs 3 cents and so with that rate you can find the cost of 54 inchest of wire so you take your 54 inches and multiply it by 3 which is the cents per inch and find that 54 inches of wire would cost you 162 cents

What form is the equation
2x + 3y = 4
given in?
A. Point-Slope Form
B. Slope-Intercept Form
C. Standard Form
D. General Form
Answer:
The answer is C.Standard Form. The rest are used when graphing. Hope this helps!
Let's verify all options to see which is correct.
A. Point slope form:This equation is not in point-slope form because if we compare the given equation with the formula, they both will be in different forms.
=> 2x + 3y = 4 and y - y₁ = m(x - x₁)Henceforth, this equation is not in point-slope form.
B. Slope intercept form:This equation is not in slope intercept form because if we compare the given equation with the formula, they both will be in different forms.
=> 2x + 3y = 4 and y = mx + bHenceforth, this equation is not in slope intercept form.
C. Standard form:This equation is in standard form because if we compare the given equation with the formula, they both will be in similar forms.
=> 2x + 3y = 4 and (a)x + b(y) = cHenceforth, this equation is in standard form.
D. General form:This equation is not in general form because if we compare the given equation with the formula, they both will be in different forms.
=> 2x + 3y = 4 and (a)x + (b)y + c = 0Henceforth, this equation is not in slope intercept form.
Conclusion:Option C is correct.Need help!

[tex]m\angle X = m\angle Z[/tex] (Opposite angles of a parallelogram)
[tex]\implies m\angle X = 70\degree[/tex]
In [tex]\triangle WXY[/tex]
WX = XY (given)
[tex]\implies m\angle XWY = m\angle XYW[/tex]
(Angles opposite to equal sides are equal)
[tex]m\angle XWY = x [/tex] (Given)
[tex]\implies m\angle XYW=x[/tex]
[tex]\implies x + x + 70\degree=180\degree[/tex]
(By angle sum postulate of a triangle)
[tex]\implies 2x =180\degree-70\degree[/tex]
[tex]\implies 2x= 110\degree[/tex]
[tex]\implies x= \frac{110\degree}{2}[/tex]

If GF = 10, GE = 12 and EF = 9, what is the length of CD?
The length of CD is the number of units on segment CD
Using the assumed parameters, the length of segment CD is 3 units
How to determine length of segment CDThe question is incomplete, as the length of segment CD cannot be explicitly calculated from the given parameters.
Using a general explanation, a possible way to calculate the length of segment CD is if triangles EFG and CDE are similar triangles where segment CD and EF are similar sides.
So, we have:
CD = k * EF
Where k is the scale factor.
Assume the scale factor is 1/3, the equation becomes
CD = 1/3 * 9
CD =3
Using the assumed parameters, the length of segment CD is 3 units

find the values of P for which the quadratic equation 4x²+px+3=0?
Find the values of P for which the quadratic equation 4x²+px+3=0 , provided that roots are equal or discriminant is zero .
Solution:-Let us Consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.
For equal roots
D = 0[tex]\quad\green{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]

120 -xx +12Step-by-step explanation:
The absolute value function multiplies its argument by -1 if and only if that argument is negative.
a)[tex]|x-120|=\begin{cases}-(x-120)&\text{for }(x-120) < 0\\(x-120&\text{for }(x-120)\ge0\end{cases}[/tex]
The first condition resolves to ...
x -120 < 0 ⇒ x < 120 . . . . . matches the given condition x < -120
So, we can simplify the expression to ...
-(x -120) = 120 -x . . . when x < -120

b)[tex]|x-(-12)|=\begin{cases}-(x+12)&\text{for }(x+12) < 0\\(x+12)&\text{for }(x+12)\ge0\end{cases}[/tex]
The second condition resolves to ...
x+12 ≥ 0 ⇒ x ≥ -12 . . . . . matches the given condition x > -12
So, we can simplify the expression to ...
x +12 . . . when x > -12

Additional comment
You may have noticed that the function |x -120| translates the absolute value function 120 units to the right. The condition x < -120 puts the boundary at 120 unit to the left of 0, well within the area to the left of the vertex. This is illustrated by the attached graph.
1. Maximum is cleaning shrimp. He cleans 4 shrimp every minute. Use time in minutes as the independent quantity and the number of shrimp as the dependent quality.
A= Is the relationship proportional or non-proportional? Explain how you can determine this using a graph and the equation.
B= Identity the unit rate of this relationship. Explain what the unit rate means in terms of the situation.
C= Create a graph of the relationship.
Answer:
Step-by-step explanation:
Relationship Equation between time and shrimps cleaned : S = 4T; Relationship is inversely proportional; Unit rate of change = 4
Given : 4 Shrimps cleaned every minute.
So, Shrimps cleaned 'S' = 4 times minutes taken 'T' ; S = 4T
The relationship between variables is proportional, as the dependent variable (shrimps) is constant multiples times the independent variable (time), & their ratio remains constant.
It is directly proportional, as both variables (shrimps & time) move in same direction. One variable increase or decrease, other variable same respectively.
Graph in this case is upward sloping curve from origin, because of direct proportional relationship respectively.
Unit rate of change denotes constant magnitude of change in a variable with other variable. It is 4 in this case, as time increases the shrimps.

Florida has a population of about 2 X 10'. The Earth has a population of about 8 X 109. About how many times more populated is the Earth than Florida?
Please Help!
Answer:
852
Step-by-step explanation:
2 times 10 is 20
8 times 109 is 872
You subtract the two values, 872-20=852
If Florida has a population of about 2 X 10'. The Earth has a population of about 8 X 109. Then 852 times more populated is the Earth than Florida.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that
Florida has a population of about 2 X 10'.
The Earth has a population of about 8 X 109.
We need to find how many times more populated is the Earth than Florida.
We know that
2 times 10 is 20
and 8 times 109 is 872
To calculate how many times more populated is the Earth than Florida. we just required to subtract 872 and 20.
You subtract the two values, 872-20=852
Hence About 852 times more populated is the Earth than Florida.

P( Take the bus | Junior) = [?]
Round to the nearest hundredth.
===================================================
Explanation:
The notation
P( Take the bus | Junior)
is the same as writing
P( Take the bus given Junior)
I replaced the vertical bar with the word "given".
Since we're given that the person is a Junior, this means we only focus on the Juniors. There are 13+20+2 = 35 Juniors and 20 of them take the bus.
20/35 = 0.5714 approximately which rounds to 0.57
This says about 57% of the Juniors take the bus.
The probability of P(take the bus/Juniors) is 0.57 or in percentage is 57%.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
We have to find the probability of who take the bus and they are juniors
P(take the bus/Juniors)
From the table, let us find the total number of juniors
Among juniors 13 students drive to school, 20 takes the bus and 2 come by walk
Total Juniors = 13+20+2
=35
P(take the bus/Juniors) = 20/35
Divide twenty by thirty five
=0.57
Hence, the probability of P(take the bus/Juniors) is 0.57 or 57%.

Find the HCF of 72 and 180
Find the measures of the interior angles of the triangle. Find A, B,C
Answer:
A 48 degrees B 88 degrees C 44 degrees
Step-by-step explanation:
All the sides of a triangle add up to 180 degrees.
Subtract the known side from 180. 180-48=132 degrees. That means 132 degrees is the total size of the unknown two angles. You can write that like this:
132=x+(x-44)
Simplify
132=2x-44
add 44
176=2x
Divide by 2
x = 88 degrees.
Now we know that angle B is 88 degrees. Now we just have to find angle C, which will be simple now that we know what x equals.
X-44
88-44
44 degrees
