the thickness of a deep dish pizza is approximately 2 x 10^-1 feet. the thickness of a thin crust pizza is approximately 5 x 10^-2 feet. how many times smaller is the thickness of a thin crust pizza compared to the thickness of a deep dish pizza?
A. 0.25
B.0.4
C4
D25
The thickness of a thin crust pizza is 4 times smaller than the thickness of a deep dish pizza.
The question asks us to compare the thickness of a deep dish pizza to that of a thin crust pizza and determine how many times smaller the thin crust is. The deep dish pizza has a thickness of 2 x 10⁻¹ feet and the thin crust pizza has a thickness of 5 x 10⁻² feet. To find how many times smaller the thin crust is, we divide the thickness of the thin crust by the thickness of the deep dish pizza:
(5 x 10⁻² feet) / (2 x 10⁻¹ feet) = 0.25

The tables below represent the profits earned by a merchandiser from four new consignments of t-shirts. Each consignment contained t-shirts of five different sizes. If we were to plot each of the t-shirt sizes and the profit earned on each new size, we would get a different graph for each consignment. Almost all the graphs showed some association between the two variables, except one consignment, which showed no association. Which of the following consignments shows no association?
In graph 2, the dots are scattered and also no association.
What is an association?
An association (relationship) between two numerical variables can be described by its form, direction, strength, and outliers. A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables.
For the given situation,
There are four new consignments of t-shirts.
Each consignment contained t-shirts of five different sizes.
Graph is plotted as shown below between each of the t-shirt sizes and the profit earned on each new size.
If one variable increases as the other variable increases, there is said to be a positive association.
Two variables have a negative association when the values of one variable tend to decrease as the values of the other variable increase.
No association means that there is no line and all the dots are scattered.
From the graph shown, in graph 2 the dots are scattered. Thus no association.
Hence we can conclude that in graph 2, the dots are scattered and also no association.

The perimeter of a rectangle is 54cm. The area of the same rectangle is 176 cm^2. What are the dimensions of the rectangle?
A. 11 cm by 16 cm
B. 8 cm by 22 cm
C. 5.5 cm by 32 cm
D. 4 cm by 44 cm
Given is rectangle with perimeter = 54 centimeters and area = 176 squared centimeters.
Let's consider the length of rectangle = L and width of rectangle = W.
We know the following formulas for rectangle :-
Perimeter = 2 x (L + W)
Area = L x W
So we have 2 x (L + W) = 54 and L x W = 176.
L + W = 27 and L x W = 176
We need to find two positive integers such that their sum is 27 and product is 176.
Using trial and error, we have two such positive integers such that 11 + 16 = 27 and 11 x 16 = 176.
So, the dimensions of rectangle would be 11cm x 16cm.
Hence, option A is correct i.e. 11 cm by 16 cm.

C.3.6 meters
D.7.1
Answer:
Option D. [tex]7.1\ m[/tex]
Step-by-step explanation:
we know that
The area of a circle is equal to
[tex]A=\pi r^{2}[/tex]
In this problem we have
[tex]A=40\ m^{2}[/tex]
substitute and solve for r

what are the properties of real numbers?
Final answer:
The properties of real numbers include closure, commutative, associative, identity, and inverse properties. These properties govern how real numbers behave in addition and multiplication operations.
Explanation:
The properties of real numbers refer to the characteristics and behavior of numbers that belong to the real number system. The real number system includes all rational and irrational numbers, such as whole numbers, integers, fractions, decimals, and square roots.
The properties of real numbers include:
Closure property: The sum or product of any two real numbers is also a real number. For example, the sum of 3.14 and 4 is 7.14, which is a real number.Commutative property: The order of addition or multiplication does not affect the result. For example, 2 + 3 is equal to 3 + 2, and 2 × 3 is equal to 3 × 2.Associative property: The grouping of real numbers in addition or multiplication does not affect the result. For example, (2 + 3) + 4 is equal to 2 + (3 + 4), and (2 × 3) × 4 is equal to 2 × (3 × 4).Identity property: The sum of a real number and zero is equal to the number itself. For example, 2 + 0 is equal to 2. The product of a real number and one is equal to the number itself. For example, 3 × 1 is equal to 3.Inverse property: Every real number has an additive inverse and a multiplicative inverse. The additive inverse of a real number is the number that, when added, gives zero as the result. For example, the additive inverse of 5 is -5, as 5 + (-5) = 0. The multiplicative inverse of a non-zero real number is the number that, when multiplied, gives one as the result. For example, the multiplicative inverse of 2 is 1/2, as 2 × (1/2) = 1.These properties of real numbers are fundamental in algebraic operations and calculations. They provide a basis for solving equations, simplifying expressions, and working with mathematical concepts.

A pilot is asked to use at least 94500 gallons of fuel and spend at least 2400 minutes to make round trips to Prague and Stockholm in his plane. Let P denote the number of round trips to Prague and S the number of round trips to Stockholm. Write an inequality that represents the condition based on the number of gallons of fuel. Write an inequality that represents the condition based on the number of minutes.
Answer: The inequality that represents the condition based on the number of gallons of fuel will be:
[tex]3300P +5700S \geq94500[/tex]
The inequality that represents the condition based on the number of minutes will be:
[tex]75P +130S\geq2400[/tex]
Step-by-step explanation:
Let P denote the number of round trips to Prague and S the number of round trips to Stockholm.
Since the plane requires 3300 gallons of fuel and 75 minutes to make a round trip to Prague and 5700 gallons of fuel and 130 minutes to make a round trip to Stockholm.
Then the inequality that represents the condition based on the number of gallons of fuel will be:
[tex]3300P +5700S \geq94500[/tex]
The inequality that represents the condition based on the number of minutes will be:
[tex]75P +130S\geq2400[/tex]

Finish the steps below to write a quadratic function for the parabola shown. Use the vertex form, f(x) = a(x – h)2 + k, and substitute in the values for h and k. f(x) = a(x – 5)2 + 3 Use another point and substitute in values for x and f(x). Solve for a. 5 = a(6 – 5)2 + 3 Write the function, using the values for h, k, and a. The function is f(x) = (x – )2 + .
Here we want to write the quadratic function for the parabola shown in vertex form.
We will get the function: f(x) = 2*(x - 5)^2 + 3
So the general function of a parabola with vertex (h, k) and leading coefficient a is:
f(x) = a*(x - h)^2 + k
Here, we know the formula:
f(x) = a*(x - 5)^2 + 3
where:
h = 5k = 3So the vertex is the point (5, 3), and we only must find the value of a to completely determine the parabola's function
We also know that:
f(6) = 5
So we can solve:
5 = a*(6 - 5)^2 + 3
5 = a*(1)^2 + 3
5 = a + 3
5 - 3 = a = 2
So we just found the value of a, replacing this on the parabola's function we get:
f(x) = 2*(x - 5)^2 + 3

In order to find which one of the given points is a solution to the equation, we need to plug each point in the equation and check which one fits in .
The equation is :
5x+2y=-9
a.(2,-4)
5x+2y=-9
LHS: 5x+2y
Plugging (2,-4) in this,
5(2) +2(-4) = 10-8 =2
RHS : -9
LHS ≠RHS
So (2,-4) is not the solution.
b.(-1,2)
5x+2y=-9
LHS: 5x+2y
Plugging (-1,2) in this,
5(-1) +2(2) = -5+4 =-1
RHS : -9
LHS ≠RHS
So (-1,2) is not the solution.
c.(-2,5)
5x+2y=-9
LHS: 5x+2y
Plugging (-2,5) in this,
5(-2) +2(5) = -10+10 =0
RHS : -9
LHS ≠RHS
So (-2,5) is not the solution.

Find the area of the following circle. (Round answer to the nearest whole number.) Circumference = 280 cm. (Hint: Find r from C = 2πr (round r to tenths); then find area). 1) 89 2)560 3)1,989 4)6,246
Answer:
4)6,246
Step-by-step explanation:
First we will find the value of r.
The formula for circumference is C = 2πr:
280 = 2(3.14)r
280 = 6.28r
Divide each side by 6.28:
280/6.28 = 6.28r/6.28
44.6 ≈ r
The formula for the area of a circle is
A = πr²
Using our value for r, we have
A = 3.14(44.6)² = 6245.9624 ≈ 6246
Area of circle is,
⇒ 11493.2 cm²
What is mean by Circle?
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
Circumference of circle = 280 cm.
Now, We know that;
Circumference = 2πr
Hence, We get;
⇒2πr = 280
⇒ 2 × 3.14 r = 380
⇒ 6.28 r = 380
⇒ r = 380 / 6.28
⇒ r = 60.5
Hence, Area of circle is,
⇒ πr²
⇒ 3.14 × 60.5²
⇒ 11493.2 cm²

Find the volume of a box that will hold nine 9.425 cm3 cylindrical containers that each measure 3 centimeters long. (round to nearest whole number)
Final Answer:
The volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.
Explanation:
First, we need to find the radius of each cylindrical container since we have its volume and the length. The volume V of a cylinder is given by the formula:
[tex]\[ V = \pi r^2 h \][/tex]
where r is the radius and h is the height (or length) of the cylinder. We are given:
[tex]\[ V = 9.425 \text{ cm}^3 \\\\\[ h = 3 \text{ cm} \][/tex]
We need to solve for r:
[tex]\[ 9.425 = \pi r^2 (3) \\\\\[ r^2 = \frac{9.425}{3\pi} \\\\\[ r^2 = \frac{9.425}{3 \times 3.14159} \\\\\[ r^2 = \frac{9.425}{9.42477} \\\\\[ r^2 \approx 1 \\\\\[ r \approx 1 \text{ cm} \][/tex]
Now we know the radius of one cylindrical container is approximately 1 cm. Although this rounding might lead to a slightly inaccurate result, we'll proceed with this approximation for simplicity's sake.
Since each container is a cylinder with a radius of 1 cm, the diameter of each container is [tex]\( 2 \times 1 = 2 \)[/tex] cm. If we wanted to pack these containers without any wasted space in one layer, we would arrange them in a 3 by 3 grid, given there are 9 containers. The length and the width of the box would then each be 3 times the diameter of one container.
Hence:
Length of box = Width of box = [tex]\( 3 \times 2 \)[/tex] cm = 6 cm.
The height of the box would be equal to the length of one of the containers, which is 3 cm.
Now we can find the volume of the box:
Volume of box [tex]\( V_{\text{box}} \) = Length \( \times \) Width \( \times \) Height[/tex]
[tex]\[ V_{\text{box}} = 6 \text{ cm} \times 6 \text{ cm} \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 36 \text{ cm}^2 \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 108 \text{ cm}^3 \][/tex]
Rounding to the nearest whole number, the volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.
