Consider the system of equations represented in the
graph.
y-x = 2
x + y = 4
Which is a solution to the system of equations?
1. (1.3)
2. (2.2)
3. (3, 1)
4. (4,2)
ONLY ONE ANSWER
Answer: 1. (1,3)
Step-by-step explanation:
Insert 1 for x and 3 for y. The equations will look like
3 - 1 = 2
1 + 3 = 4
Both equations are true when these numbers are inserted, therefore, the answer is (1,3).

explain how the formula for the volume of a cone is derived
Answer:
The volume of a cone is 1 3 π r 2 h \frac { 1 } { 3 } \pi r ^{ 2 } h 31πr2h, where r denotes the radius of the base of the cone, and h denotes the height of the cone.
Step-by-step explanation:
(happy to help)
Final answer:
The volume of a cone is derived using the principle of integrating infinitesimally thin discs along the height of the cone, given by the formula V = ⅓πr²h.
Explanation:
The formula for the volume of a cone is derived using calculus and geometric principles. Consider a cone generated by rotating a line around one of the coordinate axes. If we know the formula for the area A of a circle, it can be extended to find the volume of a cone. The area A of a circle is πr², where r is its radius. The formula for the volume V of a cone is ⅓ × base area × height, which can be expressed as V = ⅓πr²h, with h being the cone's height.
Using integral calculus, the cone's volume is found by stacking infinitesimally thin discs (each with volume πr²dx, where dx is the disc's thickness) along the cone's height. The radius r changes linearly from the base to the apex, following the relationship r = (h - x)tan(a), where a is the semivertical angle of the cone. Thus, you integrate from the apex (0) to the base (h) to find the entire volume of the cone.
A certain shampoo is available in two sizes. A 23.7-ounce bottle costs $4.97 . A 33.8 -ounce bottle costs $7.48 . Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent.
Unit price for the 23.7 Price per ounce
33.8 Price per ounce
Answer:
23.7 ounce = 20 cents per ounce
33.8 ounce = 22 cents per ounce
The 23.7 ounce bottle is a better deal because it is only 20 cents per ounce, rather than 22 cents per ounce.

Ileana buys a large circular pizza that is divided
into eight equal slices. She measures along the
outer edge of the crust from one piece and finds it
to be 5 1/2 inches. What is the diameter of the pizza
to the nearest inch?
- 4 inches
- 7 inches
- 8 inches
- 14 inches
Answer:
14
Step-by-step explanation:
the edge of one slice of pizza is 5.5 and there are eight slices so i multiplied 5.5 by eight to get the circumference
the circumference is 44 so i divided that by pi to get the diameter which was 14 after you round
if your more of a numbers/formula person this might be more helpful:
circumference: 5.5 x 8 = 44
formula for diameter is [tex]d=\frac{C}{\pi }[/tex]
so, [tex]d=\frac{44}{\pi }[/tex]
[tex]d=14[/tex]
The diameter of the pizza is 14 inches.
Given that the pizza is divided into 8 equal slices and one of the outer edges measures 5 1/2 inches.
When need to find the diameter of the pizza.
What is the formula to find the circumference of the circle?The formula to find the circumference of the circle is 2πr.
Since a pizza is divided into 8 equal parts.
So, the circumference of 1 part=2πr/8=πr/4
πr/4=5.5 inches.
⇒πr=22
⇒r=7 inches.
Then, diameter=14 inches.
Therefore, the diameter of the pizza is 14 inches.

what is the surface area of a storage box that measures 21 centimeters by 18 centimeters by 16 centimeters
Answer:
2004 cm²
Step-by-step explanation:
To solve this problem, you just need to plug your values into the rectangular prism formula: A=2(wl+hl+hw)
Assuming that the length is 21 cm, the width is 18 cm, and the height is 16 cm, your problem would look like this:
A=2((18x21)+(16x21)+(16x18))=2(378+336+288)=2x1002=2004 cm²

Select the measurements that are equivalent to one hundred grams.
1,000 mg
10,000 cg
0.1 kg
10 hg
Answer:
100 grams is = to 0.1 kg
Step-by-step explanation:
100 grams is = to 10,000 mg which is incorrect. I am not sure what the other answer choices are, but C is your correct answer.
Final answer:
The measurements equivalent to one hundred grams are 10,000 centigrams (cg) and 0.1 kilograms (kg). The other options provided do not equal 100 grams.
Explanation:
To determine which measurements are equivalent to one hundred grams, we need to understand the relationship between different units of mass. In the metric system, mass is commonly measured in kilograms (kg), grams (g), and milligrams (mg), among others. Here is a reference based on the information you provided:
1 kilogram (kg) = 1000 grams (g)
1 gram (g) = 1000 milligrams (mg)
Now, let's evaluate each option provided in the question:
1,000 mg = 1 g (not 100 g)
10,000 cg = 100 g (since 1 g = 100 centigrams (cg))
0.1 kg = 100 g (since 1 kg = 1000 g)
10 hg = 1000 g (since 1 hectogram (hg) = 100 g)
Therefore, the measurements equivalent to one hundred grams are 10,000 cg and 0.1 kg.

Lin says that the inequalities h>150 and h<160 describe her height in centimeters. what do the inequalities tell us about her height?
Answer:
Her height is in between 150 and 160
Step-by-step explanation:
Given
h > 150
h < 160
Required
What do these represent?
First, the inequalities need to be combined.
If h < 160, then this means that 160 > h.
So, h > 150 and 160 > h can be combined to form an inequality in the following form;
160 > h > 150
This.meeans 160 is greater than h and h is greater than 150.
If this is related to her height, it means 160 is greater than her height and her height is greater than 150;
In other words, her height is in between 150 and 160

There are 8 baseball players in the dugout for practice. Each player shakes hands with each of the other player ONLY ONCE.
How many handshakes are there?
Explanation:
There are 8 players. For each player, there are 7 people to shake hands with. So we have 8*7 = 56 handshakes so far; however, we double count since the sequence AB is the same as BA (where A and B are player names). Order does not matter when it comes to shaking hands. So we have to divide by 2 to fix the double count. We go from 56 to 56/2 = 28. There are 28 different combinations.
You can use the formula [tex]_nC_r = \frac{n!}{r!(n-r)!}[/tex] with n = 8 and r = 2, but the formula is a bit confusing to be honest if you aren't familiar with it. The exclamation marks indicate factorials.
Extra info: The value 28 can be found in Pascals triangle. Look at the row that starts with 1, 8, ... then note how 28 is in the third slot. Keep in mind that you start at r = 0 and count up by 1. So r = 2 corresponds to the third slot.

A salesperson earns a 2% commission rate on sales of camera equipment. Yesterday she earned $60 in commission. What were her sales that day?
To find the salesperson's total sales, we use the formula Commission = Sales x Commission Rate, where $60 is the commission earned at a 2% rate. Dividing $60 by 0.02 gives us the total sales of $3000 for that day.
The student has asked about calculating the total sales based on a commission earned by a salesperson. To find out the total sales we can use the formula: Commission = Sales * Commission Rate. Given that the salesperson earned a $60 commission at a 2% commission rate, we set up the equation: 60 = Sales * 0.02. To solve for Sales, we divide both sides by 0.02, which gives us Sales = 60 / 0.02. Thus, the total sales for that day were $3000.
