Column 2 is labeled y with entries 15, 30, 60, 75. Does this table represent a proportional relationship? 1,15 2,30 4,60 5,75 please answer this question quickly please and thank you
Answer:
The table represents a proportional relationship
Step-by-step explanation:
Given
x ------ y
1 ------- 15
2 --------30
4 ---------60
5 -------- 75
Required
Determine if the table shows a proportional relationship
To check this, we make use of the following formula;
[tex]k = \frac{y}{x}[/tex]
Where k is the proportionality constant
When x = 1, y = 15
[tex]k = \frac{15}{1} = 15[/tex]
When x = 2, y = 30
[tex]k = \frac{30}{2} = 15[/tex]
When x = 4, y = 60
[tex]k = \frac{60}{4} = 15[/tex]
When x = 5, y = 75
[tex]k = \frac{75}{5} = 15[/tex]
Since the value of k for all values of x and y is the same; i.e. 15
Then, the table represents a proportional relationship

A roller coaster accelerates from an initial speed of 6.0 m/s to a final speed of 70 m/s over 4 seconds. What's the acceleration?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{16 \: m/ {s} \: ^{2} }}}}}[/tex]Step-by-step explanation:
Given,
Initial velocity ( u ) = 6 m/s
Final velocity ( v ) = 70 m/s
Time ( t ) = 4 seconds
Acceleration ( a ) = ?
Finding the acceleration
We know that,
[tex] \boxed{\sf{acceleration = \frac{v - u}{t} }}[/tex]
⇒[tex] \sf{ \frac{70 - 6}{4} }[/tex]

Every time Luisa bakes a batch of brownies she uses 1/2 cup of chocolate if she has 3/2 cups of chocolate remaining how many batches of brownies can Luisa make
Answer:
she can make 4 batches of brownies
Step-by-step explanation:
since she already made a batch of brownie with 1/2 cup and she has 3/2 cups left, that means she can make 3 more
3+1=4
hope this helps
The batches of brownies can Luisa make is 4 batches.
It is required to find the the batches of brownies can Luisa make.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
3 batches of brownies from 3/2 cups of chocolate left.
Step-by-step explanation:
From the question, we know that:
1/2 cups of chocolate = 1 batch of brownies
3/2 cups of chocolate = x
Cross Multiply
1/2 × x = 3/2
x = 3/2/1/2
x = 3/2 × 2/1
x = 3 batches.
That means she can make 3 more
3+1=4
Therefore, the batches of brownies can Luisa make is 4 batches.

Asia contains both the highest and lowest known points on earth. Mt. Everest is a little over 29,000 feet above sea level, and the shore of the Dead Sea is about 1,370 feet below sea level. What is the approximate difference in elevation between the two points?
27,630 feet
28,370 feet
29,370 feet
30,370 feet
Answer:
30,370 feet
Step-by-step explanation:
The difference in elevations between two points will be 30370 feet.
It is given that Mt. Everest is 29000 feet above sea level and the shore of dead sea is 1370 feet below the sea level.
We have to find out the difference in elevation between the two points.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
As per the question ;
Height of Mt. Everest from sea level = 29000 ft. above
Height of shore of dead sea from sea level = 1370 feet below
As these both are in opposite directions , i.e., one above sea level and other below sea level , we should add both of these to find the difference in elevations between these two points.
i.e.,
The difference in elevations between two points will be ;
= 29000 + 1370
= 30370 feet
Thus , the difference in elevations between two points will be 30370 feet.

What is the volume of water in Eduardo's pool after he fills it for 5 \dfrac145 4 1 5, start fraction, 1, divided by, 4, end fraction minutes?
Answer:
205 litres
Step-by-step explanation:
Given:
Volume of water is given as:
[tex]V=100+20m[/tex] (in litres)
m is the time in minutes spent filling water in Eduardo's pool.
To find:
Volume of water in the pool after the water is filled for [tex]5\frac{1}{4}[/tex] minutes.
Solution:
Here, volume of water in the Pool (in litres) is given by the equation:
[tex]V=100+20m[/tex] ....... (1)
Where m is the time for which Eduardo fills the pool.
Here, we are also given that
m = [tex]5\frac{1}{4}[/tex] minutes = [tex]\frac{5\times4+1 }{4}=\frac{20+1}{4}=\frac{21}{4}[/tex] minutes
And we have to find the value of V after [tex]\frac{21}{4}[/tex] minutes.
Let us put the value of m as [tex]\frac{21}{4}[/tex] minutes in the equation (1) to find the value of V.
[tex]V=100+20m\\\Rightarrow V = 100 + 20 \times \frac{21}{4}\\\Rightarrow V = 100+105\\\Rightarrow \bold{V = 205\ litres}[/tex]
So, the volume of water in the pool after [tex]\frac{21}{4}[/tex] minutes is 205 litres.
Find the distance between the points A(10, –9) and B(8, 7). Round your answer to the nearest hundredth. A
Answer:
16.12 units
Step-by-step explanation:
distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(8 - 10)² + (7 + 9)²]
d = √[(-2)² + (16)²]
d = √[4 + 256]
d = √260

Type in the correct answer. What is the slope of line m? On a coordinate plane, a straight line goes through (negative 2, 1), (0, 0), and (2, negative 1).
Answer:
-0.5 or -1/2
Step-by-step explanation:
The equation for slope is y₂-y₁ / x₂-x₁.
It should work with all of the points given. Any of the 2 points you choose will give you the slope -0.5 or -1/2.
The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The average slope of a straight line ;
The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by
Slope = (y₂ - y₁)/(x₂ - x₁)
So slope associated with two points (-2,1) , (0,0)
⇒ (0 - 1) / (0 + 2)
⇒ -1/2
Since all three points are in a straight line so slope must be the same.
Hence "The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2".

Step-by-step explanation:
Nadia is carrying out mountain climbing.
She started climbing the mountain at an altitude of 19.26 feet below the sea level.
Nadia changed her altitude by climbing a total of 5,437.8 feet from her starting position.
Therefore, Nadia's altitude at the end of her climb can be calculated as follows
= 5,437.8-19.6
= 5,418.2
