Answer:
4
Step-by-step explanation:
The constant of proportionality is what determines the relationship between y and x. If t is the constant of proportionality then an example is y = tx .
So 4 is the constant of proportionality
Answer:
A) 4
Step-by-step explanation:
3 times 4 is twelve. 1 times 4 is 4. 7 times 4 is 28. All of the numbers on the left can be multiplied by 4 to get the answer on the right.
Wayne is hanging a string of lights 45 feet long around the 3 sides of his rectangular patio, which is adjacent to his house. The length of his patio, the side along the house, is 5 feet longer than 2 times its width. Find the length and width of the patio.
Answer:
45=2w+L and L=2w+5
45=2w+L 45=2w+(2w+5)
45=4w+5
40=4w
10=w
L=2w+5 L=2(10)+5
L=20+5
L=25
The length of the patio is 25 feet and the width of one side of the patio is 10 feet. Because there are two width sides and one length side, this all adds up to be 45 feet long.

A pancake recipe require 1 2/3 cups of flour to make 20 pancakes and you have 9 cups of flour.
a. How many pancakes can you make with 1 cup of flour?
b. How many pancakes can you make with 9 cups of flour?
C. Do you have enough to make 100 pancakes? Explain
Quantity of flour needed to make 20 pancakes =
[tex] = 1 \frac{2}{3} \: [/tex]
[tex] = \frac{3 \times 1 + 2}{3} [/tex]
[tex] = \frac{5}{3} \: cups \: of \: flour[/tex]
Then , number of pancakes that can be made from 1 cup of floor :-
[tex]20 \div \frac{5}{3} [/tex]
[tex]20 \times \frac{3}{5} [/tex]
[tex] \frac{60}{5} [/tex]
[tex] = 12 \: pancakes[/tex] .
Therefore , 12 pancakes can be made from 1 cup of floor .
Solution (b) :-Number of pancakes that can be made with 1 cup of flour = 12 pancakes
Number of pancakes that can be made with 9 cups of flour :-
= 9 × 12
= 108 pancakes
Therefore , I can make 108 pancakes with 9 cups of flour .
Solution (c) :-Yes , I have enough flour to make 100 pancakes . I say this because :-
With one cup of flour I can make = 12 pancakes
With 9 cups of flour I can make =
= 9 × 12
= 108 pancakes
As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .
What is the answer to this equation? -108=8x
The distance covered
by a car in
3x hours is
27x3_9x²+3x. Find the rate of the car
Answer:
9x²-3x+1Step-by-step explanation:
The rate of the change of the car is is its speed.
Speed = distance/time
Given
Distance = 27x³-9x²+3x
Time = 3x hours
Speed = 27x³-9x²+3x/3x
factor out 3x from the numerator:
Speed = 3x(9x²-3x+1)/3x
Speed = 9x²-3x+1
Hence the rate of the car is 9x²-3x+1

Complete the table of values to find the solutions of the equation -x + y = 6.
Answer:
Answer:
X l Y
-2 l 4
-1 l 5
0 l 6
1 l 7
2 l 8
Step-by-step explanation:
X l Y
-2 l - (-2) + y =6 => y = 6 - 2=> y = 4
-1 l - (-1) + y =6 => y = 6 - 1=> y = 5
0 l - (0) + y =6 => y = 6 + 0=> y = 6
1 l - (1) + y =6 => y = 6 +1 => y = 7
2 l - (2) + y =6 => y = 6 + 2=> y = 8

[tex]\frac{3}{5} +\frac{1}{4} +\frac{3}{8} =[/tex] Distance Janie walked
First add [tex]\frac{1}{4} and\frac{3}{8}[/tex] canvert 1/4 by multiplying by 2/2 to get a commmon denominator.
[tex]\frac{1}{4} *\frac{2}{2} =\frac{2}{8}[/tex]
[tex]\frac{2}{8} +\frac{3}{8} =\frac{5}{8}[/tex]
Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8 and 5/8 by 5/5.
[tex]\frac{3}{5}*\frac{8}{8}=\frac{24}{40}[/tex]
[tex]\frac{5}{8}*\frac{5}{5}=\frac{25}{40}[/tex]
Now add them.
[tex]\frac{24}{40}+\frac{25}{40}=\frac{49}{40}=1\frac{9}{40}[/tex]miles
You can also convert all to decimals and add.
3/5 = .6
1/4 = .25
3/8 = .375
.6 + .25 + .375 = 1.225
Also 1 [tex]\frac{9}{40}[/tex] = 1.225

Please help me :)
Answer:
x= 12
Step-by-step explanation:
(9x -4)° +(5x +16)° = 180° (int. ∠s, L//m)
9x -4 +5x +16= 180
14x +12= 180 (simplify)
14x= 180 -12 (-12 on both sides)
14x= 168
x= 168 ÷14 (÷14 on both sides)
x= 12

Question 1: A researcher wants to know about the average salary of all General Motors workers. The data can only be collected as whole US dollars. This data can be considered: * qualitative nominal qualitative ordinal quantitative discrete quantitative continuous Question 2: A researcher pla
Answer:
Quantitative Discrete
Step-by-step explanation:
The data about the average salary of all general motor workers cooled ONLY as WHOLE U. S DOLLARS
Firstly, data involving worker's salary are best expressed in figure, hence making such data numerical in nature. Numerical variables are quantitative data as it allows for numerical computation and analysis such as addition, subtraction, mean of the data values and so on.
Secondly, since these data has been strictly restricted to be expressed in whole numbers, this makes the range of the data collected finite and hence countable. This properties ensure that the quantitative data (average salary) is discrete in nature.

At the Fidelity Credit Union, a mean of 7.1 customers arrive hourly at the drive-through window. What is the probability that, in any hour, less than 2 customers will arrive
Answer:
The probability that, in any hour, less than 2 customers will arrive is 0.0067.
Step-by-step explanation:
The random variable X can be defined as the number of customers arriving hourly at the drive-through window at the Fidelity Credit Union.
The random variable X describes a finite number of occurrences of an event in a fixed time interval.
The random variable X follows a Poisson distribution with parameter λ = 7.1.
The probability mass function of X is:
[tex]P(X=x)=\frac{e^{-7.1}(7.1)^{x}}{x!};x=0,1,2,3...[/tex]
Compute the probability of less than 2 customers arriving as follows:
[tex]P(X<2)=P(X=0)+P(X=1)[/tex]
[tex]=\frac{e^{-7.1}(7.1)^{0}}{0!}+\frac{e^{-7.1}(7.1)^{1}}{1!}\\\\=0.00083+0.00586\\\\=0.00669\\\\\approx 0.0067[/tex]
Thus, the probability that, in any hour, less than 2 customers will arrive is 0.0067.

Answer:
a. [tex]\frac{5x}{(x+3)}[/tex]
b. [tex]\frac{5x}{(x+3)}[/tex]
Step-by-step explanation:
Given that:
a. [tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{5x(2x+6)}[/tex]
= [tex]\frac{50x^{2} }{10x^{2} +30x}[/tex]
= [tex]\frac{(50x)x}{(10x+30)x}[/tex]
= [tex]\frac{50x}{(10x+30)}[/tex]
= [tex]\frac{5x}{(x+3)}[/tex]
b. [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{10x(x+3)}[/tex]
= [tex]\frac{5x}{(x+3)}[/tex]
Therefore,
[tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{5x}{(x+3)}[/tex]
