The Paks bought 4 lunches for $16. The McGills bought 6 lunches for $24. The Manns bought 15 lunches for $60. The relationship of lunches to cost is a proportional relationship. What is the constant of proportionality? A. B. C. 4 D. 64
Answer:
$4
Step-by-step explanation:
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
There is positive proportionality is two variables are positively related to each other.
In this question, price of lunches is the dependent variable while number of lunches is the independent variable
$16 = b4
Divide both sides by 4 to find b
b = $4

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The shape has area 129 cm².
Now,
Since, The shape has area 129 cm².
And, The Length of the large rectangle = (12 + x) cm
And, The width of the rectangle = 9 cm
We know that;
The area of rectangle = Length × Width
⇒ 129 = (12 + x) × 9
⇒ 129/9 = 12 + x
⇒ 14.3 = 12 + x
⇒ x = 14.3 - 12
⇒ x = 2.3 cm

A family charges a trip to the zoo on a credit card. The simple interest rate is 12%. The charges are paid after 3 months. What is the total amount paid for the trip? Round your answer to the nearest hundredth.
Answer:
$180.806
Step-by-step explanation:
The computation of the total amount paid for the trip is shown below;
As we know that
Simple interest = Principal × rate of interest × time period
= (67.70 + 62.34 + 45.50) × 12% × 3 months ÷ 12 months
= 5.2662
Now the amount is
= Principal + simple interest
= 175.54 + 5.2662
= $180.806
The cost of a pen and a pencil used to be the same, but recently the cost of the pen was increased by ₹4, whereas, the cost of pencil became ₹6 less than 5 times its original value. After the revised cost, if the pen was more expensive than the pencil, what could have been the possible original value of both the products, if the initial price was a natural number?
Answer:
The possible original values of both products are ₹2 or ₹1
Step-by-step explanation:
The question is a word problem leading to simultaneous equations
Let 'x' represent the initial value of the pen and pencil
Therefore;
The final cost of the pen = x + ₹4
The final cost of the pencil = 5·x - ₹6
x + ₹4 > 5·x - ₹6
∴ ₹4 + ₹6 > 5·x - x
₹10 > 4x
₹10/4 > x
₹2.5 > x
Given that x is a natural number, therefore
x ≤ ₹2
The possible original values of both products are ₹2 or ₹1
The possible original value of both products is ₹ 1 and ₹ 2.
The question is a word problem
Let x represent the initial cost of the pen and pencil since they were initially the same price.
When the costs of the pen was increased by ₹4, its new price is x' = x + 4.
Also, the cost of pencil became ₹6 less than 5 times its original value. So, the new price of the pencil is x" = 5x - 6.
After the revised cost, if the pen was more expensive than the pencil, then we have x' > x".
So, x + 4 > 5x - 6
x - 5x > - 4 - 6
-4x > - 10
x < -10/-4
x < 2.5
Since the initial price of the both products was a natural number, the two natural number less than 2.5 are 1 and 2.
So, the possible original value of both products is ₹ 1 and ₹ 2.

A designer decides to create a larger scale model of a smart phone so that his team can work more easily on the design. The length of the screen of his model is 60 centimeters, which is 2.5 times longer than it is wide. The designer asked his team to build the screen of the actual phone with a width of 6 centimeters. What is the scale factor of the model phone to the actual phone?
Answer:
The length of the model is 250% of the width and is 60 centimeters, and the width of the actual phone is 6 so it has a scale factor of 4:1.

Write the equation of a line in slope intercept form of a line that has a slope of 3/2 and contains (6, -2).
Which of the following describes the graph of 2x + 4y < 16?
dashed line, shaded below
solid line, shaded above
solid line, shaded below
dashed line, shaded above
=============================================================
Explanation:
2x + 4y < 16 solves to y < -0.5x+4 when you isolate y. The inequality sign does not change direction because we divided both sides by a positive value (in this case, 4).
The graph of y < -0.5x+4 will be the same as the graph of 2x+4y < 16
To graph y < -0.5x+4, we graph y = -0.5x+4 which is a straight line that goes through the two points (0,4) and (2, 3). This is the boundary line of the inequality shaded region. The boundary line is a dashed line because we are not including points on the boundary that are part of the solution set. We only include these boundary points if the inequality sign has "or equal to".
We then shade below the dashed boundary line to indicate points below the boundary line. The shading is done downward due to the "less than" sign.
---------------------
Perhaps another method to find what direction we shade is we can try out a point like (0,0). The point cannot be on the boundary line.
Plug those coordinates into either equation. I'll pick the second equation
y < -0.5x+4
0 < -0.5*0+4
0 < 0+4
0 < 4
The last inequality is true, so the first inequality is also true when (x,y) = (0,0). Therefore, the point (0,0) is in the shaded region. The point (0,0) is below the boundary line y = -0.5x+4
So this is another way to see that the shaded region is below the boundary line.

What is the area of the triangle of (-5,6),(1,3),(-5,-3)
Answer :
Hey there! I'm happy to help!
To find the area of a triangle you multiply the base by the height.
We see that our base is 5 units long because it stretches from -6 to -1 on the coordinate plane. Our height is 8 because the y value goes from 3 to -5.
To find the area of a triangle, you just multiply the base by the height then divide by 2.
5(8)=40
40/2=20
The area is 20 square units.

In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
Answer:
89.8 feet
Step-by-step explanation:
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
We would solve the above question using Sine rule
The formula is given as:
DB/sin D = BC/sin B
93/sin 90 = BC/sin 75
We cross multiply
sin 90 × BC = 93 × sin 75
BC = 93 × sin 75/sin 90
BC = 89.83 feet
Approximately BC = 89.8 feet
The length of a rectangle is 10 centimeters less than its width. What are the dimensions of the rectangle if its area is 171 square centimeters?
Step-by-step explanation:
let the width = y
the length =y-10
area of rectangle=length ×breadth
171 =y-10×y
171=y^2-10y
it turns into quadratic equation
y^2-10y+171=0
cant be solved by factorization therefore use general formula
y=-b+or-√(b^2-4ab)/2a
a=1 (coefficient of y^2) ,b=-10 , c=171
y=--10+or-√{10^2-4(1)(10)}\2(1)
y=10+or-√{100-40}\2
y=10+or-√60/2
y=10+or-(7.74/2)
y=10+3.87
y=13.87cm
OR
y=10-3.87
y=6.13cm
if y=13.87 then width is 13.87&length is 13.87-10
=3.87
OR
if y=6.13 then width is 6.13&length is 6.13-10=-3.87

| 4x2 – 121 + 5 = 0 ?
Hey there!
4x^2 - 121 + 5 = 0
COMBINE your LIKE TERMS
(4x^2) (-121 + 5) = (0)
(-121 + 5) = -116
New equation: 4x^2 - 116 = 0
ADD 116 to BOTH SIDES
4x^2 - 116 + 116 = 0 + 116
Cancel out: -116 + 116 because that gives you 0
Keep: 0 + 116 because that helps you solve for x
0 + 116 = 116
New equation: 4x^2 = 116
DIVIDE 4 to both sides
4x^2/4 = 116/4
Cancel out: 4/4 because that gives you 1
Keep: 116/4 because that helps you solve for x
Equation: x^2 = ± 116/4
116/4 = 29
Answer: x = √29 OR x = √-29
