A cylinder has a base with a diameter of 6 cm, and a height of 12 cm. What is its volume?
Answers
Answer:
V≈339.29cm³
Step-by-step explanation:
Answer:
The volume of the cylinder is approximately [tex]\( 339.292 \)[/tex] cubic centimeters.
Explanation:
To find the volume [tex]\(V\)[/tex] of a cylinder, you can use the formula:
[tex]\[ V = \pi r^2 h \][/tex]
Where:
- [tex]\( \pi \)[/tex] (pi) is a mathematical constant approximately equal to 3.14159
- [tex]\( r \)[/tex] is the radius of the base of the cylinder
- [tex]\( h \)[/tex] is the height of the cylinder
Given that the diameter of the base is 6 cm, the radius [tex](\( r \))[/tex] is half of that, so [tex]\( r = \frac{6}{2} = 3 \)[/tex] cm.
The height [tex](\( h \))[/tex] of the cylinder is given as 12 cm.
Now, plug the values into the formula:
[tex]\[ V = \pi (3)^2 \times 12 \][/tex]
[tex]\[ V = 9\pi \times 12 \][/tex]
[tex]\[ V = 108\pi \][/tex]
Now, if you need a numerical approximation, you can multiply 108 by the value of [tex]\( \pi \)[/tex]:
[tex]\[ V \approx 108 \times 3.14159 \][/tex]
[tex]\[ V \approx 339.292 \][/tex]
How many solutions does this system have? 2x+8y=16,-3x+6y=30
Answers
Final answer:
To determine the number of solutions for the system of equations 2x+8y=16 and -3x+6y=30, the elimination method can be used. After multiplying and combining the equations, it is found that the system has a unique solution at (-4, 3). This means the two lines intersect at exactly one point.
Explanation:
The student is asking about the number of solutions for the system of equations 2x+8y=16 and -3x+6y=30. To find out how many solutions the system has, we can use either substitution, elimination, or graphing methods. Substitution involves solving one equation for one variable and then substituting that into the other equation. Elimination involves adding or subtracting equations to cancel out one of the variables, which can be followed by solving for the remaining variable. Graphing would involve plotting both equations and observing their intersection points.
For this specific problem:
Equation 1: 2x+8y=16
Equation 2: -3x+6y=30
If we try to use the elimination method, multiplying Equation 1 by 3 and Equation 2 by 2 would allow us to cancel out the x's:
Multiplying Equation 1 by 3: 6x+24y=48
Multiplying Equation 2 by 2: -6x+12y=60
Adding these equations together gives us:
36y=108, which simplifies to y=3. Substituting y=3 into Equation 1, we can solve for x:
2x+8(3)=16
2x+24=16
2x=-8
x=-4
Thus, the system has a unique solution (x, y)=(-4, 3), indicating that the two lines intersect at exactly one point.

Sierra simplified an expression as shown below: Given: x + 8 + 5(x - 4) Step 1: x + 8 + 5x - 20 Step 2: 5x + 8 - 20 Step 3: 5x - 12 In which step did Sierra make a mistake? What should she have done instead?
Answers
Answer:
In which step did Sierra make a mistake? Step 2.
What should she have done instead? add the x and the 5x
Step-by-step explanation:
she had the expression:
[tex]x + 8 + 5(x - 4)[/tex]
and then she multiplied the 5 by the parentheses (step 1):
[tex]x + 8 + 5x - 20[/tex]
no mistakes so far
then she has: [tex]5x + 8 - 20[/tex] (step 2) Here is the mistake, she forgot about the 'x' that she has at the beginning of the expression.
What you should have done is add the x and the 5x, so she must a 6x in the following step (correcting the mistake):
[tex]6x+8-20[/tex]
which gives us:
[tex]6x-12[/tex]
Vanessa measured 1 2/3 quarts of cherries and 1/3 quart of peaches. How many pints of fruit did Vanessa measure altogether?
Answers
Answer:
4 pints
Step-by-step explanation:
All we need to do is convert the amount of each fruit from quarts to pints and then add them up.
For Cherries:
She measured [tex]1\frac{2}{3}[/tex] quarts.
1 quart = 2 pints
=> [tex]1\frac{2}{3}[/tex] quarts = [tex]1 \frac{2}{3} * 2 = \frac{5}{3} * 2 = \frac{10}{3}[/tex] pints
For Peaches:
She measured [tex]\frac{1}{3}[/tex] quarts.
=> [tex]\frac{1}{3}[/tex] quarts = [tex]\frac{1}{3} * 2 = \frac{2}{3}[/tex] pints
Hence, the amount of fruits she measures altogether, in pints, is:
[tex]\frac{10}{3} + \frac{2}{3} = \frac{12}{3} = 4[/tex]
She measured 4 pints of fruit altogether.
Which is an equation of the line that passes through the
point (5,-2) and has a slope of -3?
Answers
Slope intercept form: y = mx + b
We know the slope, so we need to use the given point in the generic slope intercept form and solve for b.
y = -3x + b
-2 = -3(5) + b
-2 = -15 + b
b = 13
y = -3x + 13

Sandra wants to give a party for 60 people. She has a punch recipe that makes 2 gallons of punch and serves 15 people. How many gallons of punch should she make for her party? *
Answers
Answer:8
Step-by-step explanation:
Sandra wants to give a party for 60 people. Given that her punch recipe, which yields 2 gallons, serves 15 people, she can use a proportional relationship to determine she will need 8 gallons of punch.
Explanation:This question can be solved by setting up a proportional relationship. In the given case, we know that the punch recipe produces 2 gallons of punch and serves 15 people. Hence, the ratio is 2 gallons per 15 people or 2/15.
Now, let's use this ratio to calculate how many gallons of punch she will need for 60 people. Form a proportion as follows:
2/15 = x/60
Where 'x' represents the number of gallons needed for 60 people. To find 'x', cross-multiply:
2 * 60 = 15 * x
120 = 15x
Then, divide both sides by 15 to solve for 'x':
x = 120/15
So, 'x' equals 8. That means Sandra needs to make 8 gallons of punch for her party.

Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
7h – 5(3h – 8) = –72
Which statement is true about Pieter’s solution?
It cannot be a fraction or decimal because the depth of the well is a whole number.
It must be a positive number since it represents a number of hours.
It must be a negative number because the depth is below sea level.
It cannot be greater than –72 because that is the depth of the well.
Answers
Answer:
Option B is correct
It must be a positive number since it represents a number of hours.
Step-by-step explanation:
As per the statement:
Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
__________________________________________________________
Given the equation as:
Using distributive property,
Combine like terms;

Therefore, the statement is true about Pieter’s solution is, It must be a positive number since it represents a number of hours.
The statement true about Pieter's solution is that b. It must be a positive number since it represents a number of hours.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given is an equation,
7h – 5(3h – 8) = –72
where h is the number of hours taken to dig a well to a level of 72 feet below sea level.
The solution of the given equation will give the value f h, which is the number of hours taken to dig the well to a depth of 72 feet.
We know that, time can never be a negative number. So the value of h must be positive.
So the correct option is It must be a positive number since it represents a number of hours.
Solution is,
7h – 5(3h – 8) = –72
7h - 15h + 40 = -72
-8h = -112
h = 14 hours

What is bigger 2/8 or 4/16
Answers
Answer:
los dos son lo mismo solo que se multiplican por dos espero me entiendas
Step-by-step explanation:
Answer: They equal the same thing
Step-by-step explanation: Notice that the fractions that we're comparing in this problem have different denominators. When fractions have different denominators they're called unlike fractions.
To compare unlike fractions, we must first get a common denominator.
The common denominator of 8 and 16 will be the least common multiple of 8 and 16 or 16. To get a 16 in the denominator of 2/8, we multiply the numerator and the denominator by 2 which gives us 4/16.
Now notice that 4/16 is equal to 4/16 since we changed 2/8.
Since 4/8 equals 4/8, these fractions are the same

mark my brainliest? :)
Final answer:
The temperature needs to change by 4°F to reach the preferred reading at -5°F.
Explanation:
The current temperature of the restaurant's freezer is -1°F. To achieve the preferred temperature of -5°F, we need to calculate the difference between the two temperatures The temperature needs to change to reach the preferred reading is 5°. Thus,
Calculating the difference between the preferred temperature (-5°F) and the current reading (-1°F): -5 - (-1) = -5 + 1 = -4°F.Since temperatures are measured in terms of how much they deviate from zero, it needs to decrease, so the change will be positive: 4°F.Therefore, the temperature needs to decrease by 4°F to reach the preferred reading.

What is the y-intercept of the line given by the equation y = 8x + 75?
А. (0, -8)
В. (0, 75)
с. (0, -75)
D. (0, 8)
Answers
Answer: (0, 75)
Step-by-step explanation: This equation is written in slope-intercept form which is more commonly known as y = mx + b form where the multiplier or the coefficient of the x term represents the slope of the line and the b or the constant term represents the y-intercept of the line.
In this equation, we can see that the y-intercept is 75 but it's important to understand that the y-intercept is a coordinate point so I like to always write it as a coordinate point where the x value is going to be 0 and your b value is going to be your value on the y-axis. So we can write this as (0, 75).
