A filter in the shape of a cone has a diameter of 3 inches and a height of 4 inches.
How much liquid can the filter hold without it overflowing?
A) π in3
B) 3π in3
C) 12π in 3
D) 36π in3
Answer:
the correct answer in ''B''
Step-by-step explanation:
Final answer:
The cone-shaped filter with a diameter of 3 inches and a height of 4 inches can hold 3π inches³ of liquid without overflowing, which corresponds to choice B.
Explanation:
To find how much liquid can be held in a cone-shaped filter without overflowing, we use the formula for the volume of a cone, V = πr²h/3, where r is the radius, h is the height, and π (pi) is approximately 3.14. Given that the diameter of the cone is 3 inches, the radius (r) would be half of that, which is 1.5 inches. The height (h) is given as 4 inches. Plugging these values into the formula gives us:
V = π(1.5²)(4)/3 = π(2.25)(4)/3 = π(9)/3 = 3π inches³
Therefore, the cone-shaped filter can hold 3π inches³ of liquid without overflowing, which corresponds to choice B.

what is the answer to 38-19+12
To solve the expression 38-19+12, we subtract 19 from 38, resulting in 19, and then add 12 to get an answer of 31.
To solve the expression 38-19+12, we should follow the proper order of operations, which in this case, simply requires us to perform the subtraction and addition in the sequence they appear from left to right. First, subtract 19 from 38, then add 12 to the result.
Subtract 19 from 38, which equals 19 (38 - 19 = 19).
Add 12 to the result from step 1, which gives us 31 (19 + 12 = 31).
Therefore, the answer to the expression is 31.

Members of the Blade runners skating club collected $950 from fundraising activities.They want to buy Altrablade skates, which are $48 a pair. How many pairs of skates can they buy? What does the remainder represent
Answer:
19 pairs
need 21% of $48 to buy 20th pair
Step-by-step explanation:
If the members collected $950 and they want to by Altrablade skates for $48 a pair, the amount of pairs of skates can be determine by dividing the total amount collected by the cost per skates:
[tex]950/48=19.79=19[/tex]
They can buy 19 pairs of skates by the remainder is 0.79. This represents the amount still needed to buy the 20th pair of skates. So they would need 21% of the $48 to buy a extra pair.

Answer:
Ф Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.
Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.
So, X intercept - (2,0)
Y intercept - (0,3).
Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.
Now put everything together in form:
Y = mx + b
Y = -3/2x + 3.

Ellen's car averages 35 miles per gallon of gas. If you used equivalent ratios to graph her car's gas usage, how would the graph differ from the graph of Luis's car's gas usage?
The difference in the cars' graphs would depend on their respective miles per gallon ratings. A higher MPG results in a steeper line on the graph, reflecting better fuel efficiency. Therefore, the MPG rate and equivalent ratios for each car determine the graph's slope, indicating their difference in gas usage.
Explanation:The difference in graph layout would be based on the cars' fuel efficiency, i.e., miles per gallon (MPG). Ellen's car has an MPG of 35. This means that for every gallon of gas, Ellen's car can travel 35 miles. If we graph this, it would be a straight line graph, showing a constant ratio of 35 miles to 1 gallon of gas.
On the other hand, if Luis's car has a different fuel efficiency, the ratio represented on the graph would change accordingly. For instance, if Luis's car has an MPG of 20, then his car's graph would be less steep than Ellen's because his car consumes more gasoline for the same distance. Alternatively, if his car gets 40 MPG, then Luis's car's graph would be steeper than Ellen's, as his car travels further on the same amount of gas.
So, equivalent ratios and gas usage relate directly to the MPG rate of each car. Thus, the MPG rate ultimately determines the slope of each car's graph, showing how they differ in terms of gas usage for equivalent distances travelled.

To find the cost for 24 ounces of sandwich spread at $6.40 per pound, convert ounces to pounds (24 oz to 1.5 pounds) and then multiply by the price per pound, resulting in a total cost of $9.60.
To determine how much you would have to pay for 24 ounces of sandwich spread at $6.40 per pound, first, you need to convert the weight from ounces to pounds. Since there are 16 ounces in 1 pound, you would perform the following calculation:
24 ounces / 16 ounces per pound = 1.5 pounds.
Next, to find the cost, multiply the number of pounds by the price per pound:
1.5 pounds x $6.40 per pound = $9.60.
Therefore, you would have to pay $9.60 for 24 ounces of the sandwich spread.

how to do the parcial-quotients algorithm
To perform the partial-quotients algorithm, follow these steps:
1. Determine the largest multiple of the divisor that fits into the dividend without exceeding it. This multiple becomes the partial quotient.
2. Multiply the divisor by the partial quotient and write the product below the dividend.
3. Subtract the product from the dividend to find the remainder.
4. Bring down the next digit of the dividend (if there is one) to the right of the remainder, forming a new dividend.
5. Repeat steps 1-4 until there are no more digits to bring down or the remainder is less than the divisor.
6. The sum of the partial quotients is the quotient, and the final remainder is the remainder of the division.
Let's apply these steps to an example division: dividing 154 by 3.
1. The largest multiple of 3 that fits into 15 is 15 (5 groups of 3), so the first partial quotient is 5.
2. Multiply 3 by 5 to get 15, and write it below the 15 in the dividend.
3. Subtract 15 from 15 to get a remainder of 0.
4. Bring down the next digit, 4, to get a new dividend of 04.
5. The largest multiple of 3 that fits into 4 is 3 (1 group of 3), so the second partial quotient is 1.
6. Multiply 3 by 1 to get 3, and write it below the 4 in the dividend.
7. Subtract 3 from 4 to get a final remainder of 1.
The quotient is the sum of the partial quotients, which is 5 + 1 = 6, and the remainder is 1. So, 154 divided by 3 is 6 with a remainder of 1.
The partial-quotients algorithm is particularly useful for dividing large numbers because it breaks down the division into more manageable parts. It also helps with understanding the concept of division as a process of repeated subtraction.
Phil is riding his bike he writes 42 miles in 4 hours whats 52.5 miles in 5 hours and 63 miles and 6 hours find the constant of proportional and write an equation to describe the situation let X represent the #of hours.
Answer:
Step-by-step explanation:
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
d= 12.5 x t
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25miles÷2hours=12.5mileshour
A direct proportionality will always result in an equation that resembles this:
y=kx
where y and x are the related quantities and k is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)
