Which relationship is an example of a proportional relationship?
helppp?
Answer: “samuel earns $20 for each lawn he mows”
Step-by-step explanation:
The statements that represent proportional relationship are statement [1], [2] and [4].
What is proportional relationship? What is equation modelling? What is a mathematical equation and expression?The proportional relationship between [y] and [x] is given by -y = mx + c
for [c] = 0
m = y/x
where [m] is the constant of proportionality.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are some statements depicting proportional relationship.
For the statement [1], we can write the equation as -
y = 0.08x + 59
For the statement [2], we can write the equation as -
y = 25x + 45
For the statement [1], we can write the equation as -
y = 20x
Therefore, the statements that represent proportional relationship are statement [1], [2] and [4].

(n−1)a−(⌊n÷m⌋×(a−b))≥x−α1
n−1−(⌊n÷m⌋×(a−b))≥x−α1a

Mia, Thomas, and Jasmine are competing in a barrel race. Thomas's time is 8 seconds more than Mia's time. Jasmine's time is į times the quantity of 21 seconds more than Mia's time. The sum of all three times is 71 seconds. what represents this situation and what is the value of m
Given that,
Thomas's time is 8 seconds more than Mia's time.
Jasmine's time is į times the quantity of 21 seconds more than Mia's time
The sum of all three times is 71 seconds.
To find,
The value of m.
Solution,
Let Mia's time is m.
Thomas's time = 8+m
Jasmine's time = 21 + 8+ m
ATQ,
m + 8 + m + 21 + 8 + m = 71
3m + 37 = 71
3 m = 71 - 37
m = 34/3
m = 11.34
So, the value of m or Mia's time is 11.34 seconds.
Answer:
m+1/3(m+21)+m+8=71, m=24

What is the slope of y=-x+7
Answer:
-1
Step-by-step explanation:
This is the slope because x is the slope, and if there is no number in front of x then x is 1. There is also a negative in front of x which means the answer is -1.
The slope of the equation y = -x + 7 equals -1.
3 Dave can drive from Abdet to Bentall by two routes. The old route goes in roughly a straight line while the new faster route is 26% longer. Dave's average speed on the new faster route is 40% higher than his average speed on the old route. (a) By what percentage is Dave's journey time reduced by taking the new route compared to the old? [2]
Answer:
10 % of the total time will be saved on the new route with the new speed.
Step-by-step explanation:
Let x miles be the old route. Then the new route would be 1.26 x miles
Let y be the speed on the old route . Then the speed on the new route would be 1.4 y .
And let t be the time on the old route
Speed = Distance / Time
or
Time = Distance / Speed
t= x/y
Time for the new route = 1.26x/ 1.4y= 0.9 t
0.9 t means 90% of the old time will be required to cover 1.26x miles with 1.4 y speed.
And 10 % of the total time will be saved on the new route with the new speed.
Gabby has 20 coins in her pocket that are quarters, dimes, and nickels. The total value of the coins is $2.70. The number of nickels that she has is equal to the number of quarters plus the number of dimes. Choose the system of equations that can be solved to find the number of quarters, 9, dimes, d, and nickels, n, that Gabby has.
Answer:
There's 9 nickels and no dimes
Step-by-step explanation:
the quarters equal $2.25
so there is at least 9 nickel's witch equals .45 cents add them and get $2.70 so
The system of equations to find the number of quarters, 9, dim, d, and nickels, n, that Gabby has are;
n = q + dn = 10q +d = 10Since, the total value of quarters, dim, and nicke is; $2.70.
Since the number of nickels that she has is equal to the number of quarters plus the number of dimes; we have;
n = q + dSince, Gabby has 20 coins in her pocket.
n + q + d = 20Therefore 2n = 20 from n = q + d
n = 10Read more on system of equations:

Answer:
B
Step-by-step explanation:
Exponents Law:
[tex]a^{m}*a^{n} = a^{m+n}[/tex]
In exponent multiplication, if bases are same, add the powers(exponents).
Write 7.19 in expanded form: 7.19 = 7 + 0.1 + 0.09. Now apply the exponent rule.
[tex]2^{7.19}=2^{7+0.1+0.09}\\\\=2^{7}*2^{0.1}*2^{0.09}\\\\= 2^{7}*2^{\frac{1}{10}}*2^{\frac{9}{100}}[/tex]

Mr. Wood wants to put a carpet in his brand new classroom. He is going to install a carpet that is 14 feet long and 9.5 feet wide. What is the total area of the new carpet?
Answer:
133 feet²
Step-by-step explanation:
To find the area of a shape you need to use the the formula "length(L) times(×) width(W)". In this problem it gives you both the length and width which means you just need to multiply the two numbers to get your answer. (You need to add feet because that's what is being used in the problem and ²(squared) because area is measured in square units.

1.3.PS-44 Question Help A housekeeper had 2 3 of a spray bottle of a cleaning solution. She used 1 4 of the solution in a day. How much of the bottle did she use?
Answer:
[tex]\bold{\frac{1}{6}}[/tex] of the bottle was used
Step-by-step explanation:
Amount of cleaning solution present in spray bottle = [tex]\frac{2}3[/tex] of the bottle
Amount of cleaning solution present in the spray bottle used = [tex]\frac{1}4[/tex] of the cleaning solution present initially
To find:
How much of the bottle was used?
Solution:
Here, we need to find how much amount of the cleaning solution spray was used from the complete bottle.
Amount of spray used = [tex]\frac{1}{4}\times \frac{2}{3}[/tex] of the cleaning solution = [tex]\bold{\frac{1}{6}}[/tex] of the cleaning solution.
Therefore, the answer is:
[tex]\bold{\frac{1}{6}}[/tex] of the bottle was used
