Brand A:
height of cone = 15 in.
radius of cone base=6 in.
Brand B:
height of cone = 18 in.
radius of cone base=5 in.
A. Brand A
B. Brand B
C. Either - the hats have equal volumes
Brand A hat is more preferable with largest volume i.e. 565.2 cu. inches.
What is Cone?A cone is a distinctive three-dimensional geometric figure that has a flat surface and a curved surface, pointed towards the top.
Here, Given data are:
Height of cone for Brand A = 15 in.
Radius of cone of Brand A =6 in.
Volume of Cone of brand A = [tex]\frac{1}{3}\pi r^2h[/tex]
V =[tex]\frac{1}{3}X 3.14X6^2X15[/tex]
V = 565.2 cu. in.
Height of cone for Brand B = 18 in.
Radius of cone of Brand B =5 in.
Volume of Cone of brand A = [tex]\frac{1}{3}\pi r^2h[/tex]
V =[tex]\frac{1}{3}X 3.14X5^2X18[/tex]
V = 471 cu. in.
Volume of brand A > volume of brand B.
Thus, Brand A hat is more preferable with largest volume i.e. 565.2 cu. inches.

Select all expressions that are squares of linear expressions. Group of answer choices x2+6x+36 (12x+4)2 (2d+8)(2d−8) p2−6p+9 x2+36 9x2−36
Answer:
(12x+4)² and p²−6p+9
Step-by-step explanation:
From the given choices, we areto select the one that are squares of linear expressions
1) For the expression (12x+4)²
This is regarded as the square of 12x+4 since the expression 12x4 is enclosed in parenthesis
2) For the expression p^2−6p+9
Factorize;
p^2−6p+9
p^2−3p-3p+9
p(p-3)-3(p-3)
(p-3)(p-3)
(p-3)²
Hence p^2−6p+9 is a square of the expression p-3
This are the only two required expressions (12x+4)² and p²−6p+9

Isabella opened a savings account and deposited $25,000.00. The account earns 20% interest, compounded annually. If she wants to use the money to buy a new car in 2 years, how much will she be able to spend on the car?
Answer:
$11,000
Step-by-step explanation:
1st year the account earned 20% from $25,000 = $5,000 | total = $30,000
2nd year the account earned 20% from $30,000 = $6,000
by adding the earnings of 2 years, she will be able to spend $5,000 + $6,000 = $11,000

A jar has 5 red marbles, 3 blue marbles, and 2 green marbles. what is the probability that you would choose a red marble, return it, then choose a green Marble?
Answer:
In Fraction = 10/100 simplified = 1/10
Decimal = 0.1
Percentage = 10%
Step-by-step explanation:
We add all marbles = 5+ 3+ 2 = 10
Event 1 = Red = 5/10
Event 2 = Green = 2/10
We follow this path and multiply = 2 x 5 / 10 x 10 = 10/100 = 1/10

Arnav is selling boxes of cookies.
He sells each box for $3.75.
His goal is to make more than $30.
How many boxes of cookies could he sell to reach his
goal?
Arnav needs to sell more than 8 boxes of cookies to reach his goal of making more than $30. Since the number of boxes must be a whole number, Arnav would need to sell at least 9 boxes of cookies to achieve his goal.
To determine how many boxes of cookies Arnav needs to sell to reach his goal of making more than $30, we can set up an inequality based on the selling price of each box.
Let's represent the number of boxes he sells as "x". Since each box is sold for $3.75, the total amount of money he will earn from selling "x" boxes is 3.75x.
To reach his goal of making more than $30, we can write the following inequality:
3.75x > 30
To solve for "x", we divide both sides of the inequality by 3.75:
x > 30 / 3.75
Simplifying the right side of the inequality, we get:
x > 8
To fulfil his objective of earning more than $30, Arnav must sell more than 8 boxes of cookies. Arnav would need to sell at least 9 boxes of cookies in order to reach his objective because the number of boxes must be a whole number.

Shane is mountain climbing with Naomi and had just climbed a 7.8 meter vertical rock face. Naomi is standing 6.2 meters away from the bottom of the cliff, looking up at Shane. How far away are Shane and Naomi? If necessary, round to the nearest tenth
Answer:
1.6 meters
Step-by-step explanation:
The distance between Shane and the bottom of the cliff is 7.8 meter while Naomi is standing 6.2 meters away from the bottom of the cliff.
As such, the distance between Shane and Naomi would be the difference between Shane's distance from the bottom of the cliff and Naomi's distance from the bottom of the cliff
= 7.8 - 6.2
= 1.6 meters
This is already in the nearest tenth

Mrs. Foust wants to know Aziza’s age. She knows that Aziza is the middle child. Her sister, Capri, is 4 years older than Aziza, and her sister, Portia, is 5 years younger than Aziza. The sum of their ages is 38. Let a represent Aziza’s age. Which statements are true about this scenario? Check all that apply.
Answer:
The expression that represents Capri’s age is a + 4.
The expression that represents Portia’s age is a – 5.
Step-by-step explanation:
The expression that represents Capri's age is a + 4.
The expression that represents Portia's age is a -5.
To write an equation for this scenario, Capri's age needs to be equal to Portia’s age
The equation used to represent this scenario is a + a + 5 + 2 - 4 = 38.
Solving this equation will give Aziza's age.
Aziza'a age = a
Portia age = a - 5
Capri's age = 4 + a
a + a - 5 + 4 + a = 38
