Each gallon of gasoline costs $2.35. The equation y=2.35x can be used to represent this situation.
What is the constant of proportionality? Express your answer in decimal form.
Answer:
For every gallon of gas added to the tank, the buyer is charged $2.35
The constant of proportionality of the given equation y = 2.35x will be 2.35.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Let's x ∝ y
Then x = ky where k will be constant of proportional.
k = x/y which means when two variables are divided which were in proportion it will create a constant proportional.
So,
y /x = 2.35 will be constant of propotional.
Hence "The constant of proportionality of the given equation y = 2.35x will be 2.35".

Which one A. B. C. or D.
Answer:
c
Step-by-step explanation:
because if it leaks 2 ml pe second that means we have to find out how much it leaks in 60 seconds so 2 x 60 = 120 but all the answers have the unit L beside them, not ml so 1000 ml is 1 L so that means that 120ml in L would not be a whole number so it has to be a decimal so c ( but you should still double-check just in case)

Write the equation of the line that passes through the points (3, -4) and (-3, 0) in slope-intercept form.
Step 1: Use the slope formula y₂ - y₁/x₂ - x₁ to find the slope.
[tex]\frac{0 - (-4)}{-3 - 3}\\ \\\frac{4}{-6} = -\frac{2}{3}[/tex]
Step 2: Plug the slope we found and one point into the slope-intercept formula, y = mx + b.
[tex]y = mx + b\\\\0 = -\frac{2}{3}(6) + b\\\\0 = -4 + b\\\\4 = b[/tex]
Step 3: Put it all together.
[tex]y = -\frac{2}{3}x + 4[/tex]

Answer:
115 Degrees
Step-by-step explanation:
Isosceles Triangles have two congruent base angles so if one is 50 degrees, 180-50=130 degrees the base angles must be 130/2=65 degrees each. ACB is 65 degrees and makes a line with BCE, so their sum must be 180 degrees. 180-65= 115 Degrees= BCE

A researcher studies the rate of progress of a chemical reaction. The researcher fixes the temperature and pressure, varies the amount of catalyst used over a range of quantities, and observes the resulting reaction rate in each case.
Which statement BEST describes why the investigation is an experimental study?
There is more than one independent variable to study.
The researcher manipulates at least one independent variable.
It is possible to get data with a range of values of an independent variable.
There is a cause-effect relation between the independent and dependent variables.
Answer:
I think the answer is The researcher manipulates at least one independent variable. Hope this helps.
Step-by-step explanation:
The BEST statement describes is that "The researcher manipulates at least one independent variable."
What are independent and dependent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.
The variables who take their values based on some other variables' values are called dependent variables.
Given that researcher studies the rate of progress of a chemical reaction.
The researcher fixes the temperature and pressure, varies the amount of catalyst used over a range of quantities, since we know that If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.
Therefore, the BEST statement describes why the investigation is an experimental study;
"The researcher manipulates at least one independent variable."

Answer:
$7.25Step-by-step explanation:
"Kristina sold 8 pumpkins for $3.50 each, 6 for $8.00 each, and 15 for $1.00 each. She receives $0.25 for each pumpkin sold plus a $10.00 bonus if her sales total $95.00 or more. How much did she receive?"
Given data
The total number of pumpkin is 8+6+15= 29 pumpkin
total cost of pumpkin=
8*3.5=$28
6*8=$48
15*1=$15
total is $28+$48+$15= $91
the total amount sold is not up to $95, so she will not receive the $10 bonus

Timothy and Alondra are cutting strips of poster paper for an art project.
Timothy cut 10 strips of poster paper that are each 3 feet inches long.
Alondra cut 10 strips of paper that are same length as Timothy’s strips of paper, but measured them as 106.68 centimeters long.
If Alondra cuts a strip of poster paper that is 220 centimeters long, what is the approximate length of the strip in feet that Timothy will measure.
please answer, fast!
Answer:
answer B
Step-by-step explanation:
I
there's 3 feet and 9 inches of paper on timothy's side
alondra cuts the zame amount of strips at 106.68m
there are 2.54 centimeters in one inch.
there are 12 inches in a foot
12 ×3 is 36 plus 9 is 45 inches
now, divide 106.68 by 2.54 to get 42 inches (we have 3 left over
if we subtract 220 by 106.68 we get 113.12
2.54 centimeters equals 1 inch, divide 113.12 to get 44.6
convert this to feet and we get 3 feet and 8 inches
3 feet 8 onches plus 3 feet 10 inches is 7.7 (by rounding)

Jaime is analyzing the exponential function y=19(0.91)^x. What is the growth or decay rate? Answer choices: A. 9% growth. B. 9% decay. C. 91% growth. D. 91% decay.
PS. I don't really understand this because this is new but can someone please find this as soon as possible <3. The x is an exponent.
Answer: Jaime is James
Step-by-step explanation: Remember that the original exponential formula was y = abx. You will notice that in these new growth and decay functions, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r). The growth "rate" (r) is determined as b = 1 + r.
3. At a bargain store, Spongebob bought 3 items that each cost the same amount. Patrick bought 5 items that each cost the same amount, but each was $1.50 less than the items that Spongebob bought. Both Spongebob and Patrick paid the same amount of money. What was the individual cost of each person's items?
Answer: Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1
Step-by-step explanation:
Let x be the cost of each item bought by Spongebob.
Then, cost of each item bought by Patrick = x- 1.50
Then, cost of 3 items bought by Spongebob = 3x
Cost of 5 items bought by Patrick = 5(x-1.50)
If both Spongebob and Patrick paid the same amount of money then
[tex]3x= 5(x-1.5)\\\\\Rightarrow\ 3x=5x-1.5\times5\\\\\Rightarrow\ 3x=5x-7.5\\\\\Rightarrow\ 5x-2x=7.5\\\\\Rightarrow\ 3x=7.5\\\\\Rightarrow\ x=\dfrac{7.5}{3}\\\\\Rightarrow\ x=2.5[/tex]
Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $2.5-$1.5=$1
Hence, Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1
Answer: Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1
Step-by-step explanation:
Let x be the cost of each item bought by Spongebob.
Then, cost of each item bought by Patrick = x- 1.50
Then, cost of 3 items bought by Spongebob = 3x
Cost of 5 items bought by Patrick = 5(x-1.50)
If both Spongebob and Patrick paid the same amount of money then
Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $2.5-$1.5=$1
Hence, Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1

What is the equation of a line with slope -2/7 and intercept (0, -1)?
A) y = -2/7x
B) x = -2/7y - 1
C) y = -1
D) y = -2/7x - 1
Please show work so I can understand.
Answer:
D
Step-by-step explanation:
Recall the slope-intercept form of a line:
y = mx + b
slope -2/7 means m = -2/7
y = -2/7x + b
Intercept at (0, -1)
x = 0 and y = -1.
Hence, let's plug it back into the equation we made earlier (y = -2/7x + b)
(-1) = -2/7(0) + b
-1 = b
b must be -1
y = -2/7x -1

∠GHK is a straight angle.
Find m∠LHK .
Answer:
∠ LHK = 101°
Step-by-step explanation:
The 2 angles on a straight line are supplementary, thus
∠ LHK = 180° - 79° = 101°
The given parameters are illustrations of angles on a straight line. The measure of [tex]\angle LHK[/tex] is [tex]101^o[/tex]
Given that:
[tex]\angle GHL = 79^o[/tex]
Using the angle on a straight line theorem, we have:
[tex]\angle GHL + \angle LHK =180^o[/tex] ---- angle on a straight line is 180
Substitute [tex]\angle GHL = 79^o[/tex]
[tex]79^o + \angle LHK = 180^o[/tex]
Collect like terms
[tex]\angle LHK = 180^o - 79^o[/tex]
[tex]\angle LHK = 101^o[/tex]
Hence, the measure of [tex]\angle LHK[/tex] is [tex]101^o[/tex]
