Answer:
(75/2) in^2, or approximately 37.5 in^2
Step-by-step explanation:
The equation for the volume of a cone of base area b and height h is
V = (1/3)(b)(h).
Let's solve this for b, since b is the unknown here.
Multiplying both sides of this equation by 3, we get:
3V = (b)(h), and so
b = (3V)/h
In this particular case we're given V = 75 in^3 and h = 6 in. Substituting these values into the above formula for b, we get:
3(75 in^3)
b = ------------------- = (75/2) in^2, or approximately 37.5 in^2
6 in

Answer:

Step-by-step explanation:
The interquartile range is (the middle of the upper half) - (the middle of the lower half). To find this list out all of the values and find the median, then find the center of the upper half and the lower half.
1 2 2 3 3 3 4 4 5 6 Here I have made a small diagram of how you were to find the middle of each half with the underline being each half, the bold being the sides for each half, and the italicized being the value. For this question the middle of the upper half is 4 and the middle of the lower half is 2, so 4-2 = 2.
y = (x2 - 2x + 1)
y = (x - 1)(x - 1)
Prove that the following functions are equivalent through algebraic and numerical proof
Answer:
see below
Step-by-step explanation:
y = (x² - 2x + 1)
y = (x - 1)(x - 1)
First, recognize that the first equation is fully simplified/expanded already.
Now, we should solve for the second equation.
FOIL the expressions: first–outer–inner–last
(x - 1)(x - 1)
F: x²
O: -x
I: -x
L: 1
Combine these terms.
x² - x - x + 1
x² - 2x + 1
Notice that this equation is identical to our first equation. Therefore, the functions are equivalent.
Hope this helps!
y = (x^2 - 2x + 1)
y = (x - 1)(x - 1)
Algebraic Proof
FOIL y = (x - 1)(x - 1)
y = (x - 1) (x -1 ) = x^2 -2x + 1
Done.
Numeric Proof
Let x = 1
y = x^2 - 2x + 1
y = (1)^2 - 2(1) + 1
y = 1 - 2 + 1
y = 2 + 2
y = 0
Let x be 1 again.
y = (x - 1)(x - 1)
y = (1 - 1)(1 - 1)
y = 0
There you have it. Both equations are the same.

[52 + (48 divided by 8)] + 17
Answer:
75
Step-by-step explanation:
48/8 = 6
6 + 52 = 58
58 + 17 = 75!
The solution to the expression [52 + (48 divided by 8)] + 17 is 75.
To solve the expression [52 + (48 divided by 8)] + 17, follow the order of operations, which is commonly remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
Step 1: Evaluate the division inside the parentheses.
48 divided by 8 equals 6.
Therefore, the expression becomes:
[52 + 6] + 17
Step 2: Perform the addition inside the brackets.
52 + 6 equals 58. The expression simplifies to:
58 + 17
Step 3: Evaluate the final addition.
58 + 17 equals 75.
Therefore, the solution to the expression [52 + (48 divided by 8)] + 17 is 75.

Scarlett went shopping for a new pair of pants. Sales tax where she lives is
4%. The price of the pair of pants is $41. Find the total price including tax.
Round to the nearest cent.
Answer:
39.36
Step-by-step explanation:
1% of 41 is .41, so you multiply that by 4 to get 1.64. Then do 41-1.64=39.36
The total price including tax is $42.64
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Price of pants= $41
Sales tax= 4%
So, the tax is
= 41 x 4%
= 41 x0.04
= $1.64
Now, the price of pants after tax
= 41 + 1.64
= $42.64
Hence, the total price including tax is $42.64

David has a bag of coins. The bag contains 7 dimes, 2 nickels, and 6 pennies. He will randomly select 2 coins from the bag one at a time
without replacement. What is the probability that David will select a dime first and then a penny?
Answer:
7/15 for dime
6/15 for pennies
Step-by-step explanation:
7/15 because 7+2+6=15 and there are 7 dimes so 7/15.
6/15 because there are 15 coins and there are 6 pennies so 6/15.
15 is the total so 7 and 6 have to go over it.
The ratio of the measures of the angles in a triangle is 11:2:5 find the measures of the largest angle
9514 1404 393
Answer:
110°
Step-by-step explanation:
The total of the ratio units is 11 +2 +5 = 18. These stand for the total of angles, 180°, so each ratio unit stands for 180°/18 = 10°.
The largest angle is 11 ratio units, or 11×10° = 110°.

Help! The measure of the exterior angle of the triangle is???
Answer:
92°
Step-by-step explanation:
The exterior angle is equal to the sum of the 2 opposite interior angles, that is
2x - 2 = x + 45 ( subtract x from both sides )
x - 2 = 45 ( add 2 to both sides )
x = 47
Then
exterior angle = 2x - 2 = 2(47) - 2 = 94 - 2 = 92°

A walkway forms one diagonal of a square playground. The walkway is 24 m long. How long is a side of the playground?
The diagonal of a square can be obtained by the Pythagorean theorem and is given by:
Diagonal = root (L ^ 2 + L ^ 2)
Where,
L: Sides of the squares
Clearing L, we have:
(Diagonal) ^ 2 = L ^ 2 + L ^ 2
(Diagonal) ^ 2 = 2L ^ 2
L ^ 2 = ((Diagonal) ^ 2) / 2
L = (((Diagonal) ^ 2) / 2) ^ (1/2)
Substituting
L = (((24) ^ 2) / 2) ^ (1/2) = 16.97
The side of the playground is 16.97m long

If Brenda decides to use milliliters and leaders in terms room instead and each person at the party will drink about 750 mL after 32 people and they each drink about 750 mL how many liters of punch open does mom need to buy?
Answer:
24 litres
Step-by-step explanation:
Given that :
Number of people present at party = 32
Volume of drink consumed by each person in mL = 750 mL
To consumption in mL:
Number of people * volume consumed by each
32 * 750 mL
24000 mL
24000 mL to L
1000 mL = 1 L
24000 mL = (24000/ 1000)L
