Answer:
The can's volume is 35.34 inches
the cone's volume is 11.78 inches
hope it helps you!!
The question asks for the volume of a cylinder and a cone, both with a height of 5 inches and a diameter of 3 inches. The volume of the cylinder is calculated as approximately 35.34 inches³, and the volume of the cone is about 11.78 inches³.
The question involves finding the volume of two different 3-dimensional shapes: a cylinder (soda can) and a cone (ice cream cone). To calculate the volume of the cylinder, we use the formula V = π r² h, where r is the radius of the circular base, and h is the height of the cylinder.
Since the diameter of the soda can is given as 3 inches, the radius (which is half of the diameter) would be 1.5 inches. For the cone, the formula for volume is V = {1}/{3} π r² h, using the same measurements for r and h as the soda can. The calculations then proceed as follows:
Cylinder: V = π (1.5)² × 5 = π × 2.25 × 5
Cone: V = {1}/{3} π (1.5)² × 5 = {1}/{3} π × 2.25 × 5
The volume of the cylinder would be approximately 35.34 inches³ and the volume of the cone would be about 11.78 inches³, assuming π is approximately 3.14159.

what is the coefficient for x2 -5x+6
The coefficient for x² in the equation x² - 5x + 6 is 1, as it is the implied coefficient when no numerical coefficient is written before a term in a polynomial.
Explanation:The coefficient for x2 in the polynomial equation x2 - 5x + 6 is implied to be 1. When a term in a polynomial has no numerical coefficient written, it is understood that the coefficient is 1. In any polynomial equation of the form ax2 + bx + c = 0, the coefficient of x2 is represented by a. In the given expression, since there is no number in front of x2, a is 1. Therefore, the coefficient of x2 in the equation x2 - 5x + 6 is 1.
In ΔDEF, the measure of ∠F=90°, ED = 65, FE = 56, and DF = 33. What is the value of the cosine of ∠D to the nearest hundredth?
Answer:
[tex]cos(D)=0.51[/tex]
[tex]m\angle D=59.49^o[/tex]
Step-by-step explanation:
we know that
In the right triangle DEF
[tex]cos(D)=\frac{DF}{ED}[/tex] ---> by CAH (adjacent side divided by the hypotenuse)
substitute the given values
[tex]cos(D)=\frac{33}{65}=0.51[/tex]
using a calculator
[tex]m\angle D=cos^{-1}(\frac{33}{65})=59.49^o[/tex]
To find the value of the cosine of angle ∠D in triangle ΔDEF, use the cosine formula with the given side lengths which is 59.49 degrees.
Explanation:In the given triangle ΔDEF, the measure of angle ∠F is 90°. We are given the lengths of the sides DF, FE, and ED as 33, 56, and 65 units respectively. To find the value of the cosine of angle ∠D, we need to use the cosine formula:
cos(D) = (DF2 + DE2 - EF2) / (2 * DF * DE)
Substituting the known values, we have:
cos(D) = (332 + 652 - 562) / (2 * 33 * 65)
= 59.49
Simplifying this expression gives us the value of the cosine of angle ∠D.

if p is 2% of k. What is 50% of k intems of P and k and if 10% of a number is 7. What is 80% of the number?
Answer:
a.p/100
b.56
Step-by-step explanation:
2% of p=k
2/100 ×p=k
2p/100=k
Cross multiply 2p=100k
P=100k/2
p=50k
Let's make k the subject of formula
k=p/50
So 50% of k in terms of p
50/100×k
And k=p/50
So let's substitute
50/100×p/50
P/100
Therefore 50%of k=p/100
Let the unknown number be x
10% of x is 7
10/100×x=7
10x/100=7
Cross multiply
10x=(100)(7)
10x=700
Divide both sides by 10
X=70
So 80% of 70
80/100×70
5600/100
=56
Therefore 80% of 70=56

Max wants to paint a wall that measures 2.1 m by 5.2 m. A tin of paint states that it will cover 3.5 m?. If the tin contains exactly 0.5 litres of paint, and all other measurements are correct to 1 d.p., find the maximum volume of paint needed to paint the wall.
Final answer:
The maximum volume of paint required is 2 liters.
Explanation:
To calculate the maximum volume of paint needed to paint the wall, we need to first determine the area of the wall. The wall measures 2.1 m by 5.2 m, so the area is:
Area = Length × Width = 2.1 m × 5.2 m = 10.92 m²
Now, we know that one tin of paint covers 3.5 m² and contains 0.5 liters of paint. To find the number of tins needed, we divide the total area by the area covered by one tin:
Tins needed = Total area / Area per tin = 10.92 m² / 3.5 m²
Tins needed = 3.12
Since we cannot buy a fraction of a tin, we need to round up to the nearest whole number, which means Max needs 4 tins of paint. To find the total volume of paint, we multiply the number of tins by the volume of one tin:
Total volume = Tins needed × Volume per tin = 4 × 0.5 L = 2 L
Therefore, the maximum volume of paint Max will need is 2 liters.

how many ounces of a 12 alcohol solution must be mixed with 6 ounces of a 20% alcohol solution to make a 16% alcohol solution?
Answer:
6 ounces
Step-by-step explanation:
So set your equation up as
12(x)+20(6)=16(x+6)
You set it up this way because with the first number you know the percet but not the ounces so your ounces would be x. The second set you know percet and ounces (the percent will alway go outside the parenthesis). then the last number is waht it wil equal; again we know the percent but not the product. We put x+6 in the parenthesis because you are adding the ounces your don't know(x) wiht the ones you do (6).
To solve distribute
12x+120=16x+96
Now all you have to do is solve for x. Subtract the 96 over then subtract the 12x over, so it would look like this.
12x+120=16x+96
-96 -96
12x+24=16x
-12x -12x
24=4x Now simply divide by 4 and you get 6=x
There should be 6 ounces mixed in order to get the required solution.
Let the number of ounces be represented by x.
Based on the equation, the equation to use will be:
12(x) + 20(6) = 16(x + 6)
Expand the equation
12x + 120 = 16x + 96
Collect like terms
16x - 12x = 120 - 96
4x = 24
Divide both side by 4
4x/4 = 24/4
x = 6
Therefore, the number of ounces will be 6 ounces.

6x2+4x−3=0
Answer:
x1 = 0.45 and x2 = -1.12
Step-by-step explanation:
To solve the equation 6x2+4x−3=0 using the quadratic formula, we use the following equation:
x = [-b ± √(b2 - 4ac)] / 2a
Where a, b and c are coefficients of the quadratic equantion (in our case, a = 6, b = 4 and c = -3)
So we have that:
x1 = [-4 + √(16 + 72)] / 12 = (-4 + 9.3808) / 12 = 0.4484
x2 = [-4 - √(16 + 72)] / 12 = (-4 - 9.3808) / 12 = -1.1151
Rounding to nearest hundredth, we have x1 = 0.45 and x2 = -1.12

Simplify by using Order of operations: 15/1+4 + 6+3/3
To simplify the expression 15/1+4 + 6+3/3, we perform the division operations first, followed by addition, which results in the simplified expression of 26.
To simplify the expression 15/1+4 + 6+3/3 using the order of operations, we must follow specific rules. The order of operations is often remembered by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). In the absence of parentheses and exponents in this expression, we'll focus on the multiplication/division and addition/subtraction.
First, let's look at the division and multiplication. Since there's no multiplication, we only need to perform the division operations, and we proceed from left to right:
15/1 = 15 (since any number divided by 1 is the number itself)3/3 = 1 (since any number divided by itself is 1)Now we are left with the addition operations:
15 + 4 + 6 + 1 = 26
Therefore, the simplified expression is 26. To generate accurate answers, always follow the order of operations diligently.
The simplified expression is [tex]\( 26 \).[/tex]
To simplify the expression using the order of operations (PEMDAS/BODMAS), we follow these steps:
1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
Given the expression [tex]\( \frac{15}{1} + 4 + 6 + \frac{3}{3} \),[/tex] let's simplify it step by step:
1. Solve the division: [tex]\( \frac{15}{1} = 15 \) and \( \frac{3}{3} = 1 \).[/tex]
2. Now, we have:[tex]\( 15 + 4 + 6 + 1 \).[/tex]
3. Perform addition from left to right: [tex]\( 15 + 4 = 19 \), \( 19 + 6 = 25 \), \( 25 + 1 = 26 \).[/tex]
Therefore, the simplified expression is [tex]\( 26 \).[/tex]

-3 x f(-8) +7 x g(2)
The composite function -3 x f(-8) +7 x g(2) has a value of 53
How to evaluate the composite function
From the question, we have the following parameters that can be used in our computation:
f(x) = 2x + 3 and g(x) = x
Calculating f(-8) and g(2), we have
f(-8) = 2 * -8 + 3 and g(2) = 2
Evaluate
f(-8) = -13 and g(2) = 2
Using the above as a guide, we have the following:
-3 x f(-8) +7 x g(2) = -3 * -13 + 7 * 2
Evaluate
-3 x f(-8) +7 x g(2) = 53
