NEED HELP 25 POINTS PLEASE HELP.The students at Harrison Middle School are being split into groups for a community service project. The school faculty has decided that each grade (6th, 7th, and 8th) will be split up into their own set of groups. The faculty has also decided that it is important for each grade to be split evenly into groups, with no leftover students, so that each group in a grade has exactly the same number of boys and girls. For each of the following grades, determine the largest number of groups that can be made and the number of boys and girls that will be in each group. The 6th grade has 64 girls and 72 boys. The 7th grade has 81 girls and 63 boys. The 8th grade has 68 girls and 60 boys. Please list down how many groups each grade has for both boys and girls.
Evaluate the integral. 2 (6t i − t3 j + 2t3 k) dt 0
The integral of the vector field 2 (6t i − t3 j + 2t3 k) from 0 to t can be broken down into three separate integrals for each component, yielding the resulting integral vector of (6t^2)i - (0.5t^4)j + (t^4)k.
Explanation:The integral you're asking about is a vector field integral, which comes up primarily in physics-related problems. The integral of a vector field, in this case, 2 (6t i − t3 j + 2t3 k) with respect to time, can be broken down into three separate integrals, each corresponding to a different component.
To solve, you would perform each integral separately:
Integral from 0 to t of 2*6t dt = 6t^2 between 0 and t = 6t^2 Integral from 0 to t of 2*-t^3 dt = -0.5*t^4 between 0 and t = -0.5t^4 Integral from 0 to t of 2*2t^3 dt = t^4 between 0 and t = t^4Combine these answers to yield the integral vector (6t^2)i - (0.5t^4)j + (t^4)k as the solution. Please remember to always check your calculations to ensure accuracy!

The temperature of dry ice is -109.3°F, which is 183.6°F less than the outside temperature. What is the outside temperature?
To find the outside temperature, add the difference of 183.6°F to the dry ice temperature of -109.3°F, yielding an outside temperature of 74.3°F.
Explanation:The student is asking to find the outside temperature given that dry ice temperature is -109.3°F and that the outside temperature is 183.6°F higher than the dry ice. We can solve this by adding the temperature difference to the dry ice temperature.
Let's denote the outside temperature as T.
T = (-109.3°F) + 183.6°F
Now, let's perform the addition:
T = 74.3°F
Therefore, the outside temperature is 74.3°F.
Final answer:
The outside temperature can be calculated by subtracting 183.6°F from the temperature of dry ice (-109.3°F).
Explanation:
The outside temperature can be calculated by adding the temperature difference to the temperature of dry ice. The temperature difference is given as 183.6°F less than the outside temperature, which means we need to subtract 183.6°F from the temperature of dry ice (-109.3°F). So, the outside temperature would be -109.3°F + (-183.6°F) = -293.9°F.

Standard form of 210 million, 64 thousands, and fifty
The standard form of 210 million, 64 thousands, and fifty is 210,064,050. This is found by adding the values of each place: 210,000,000 for million, 64,000 for thousand, and 50 for the units.
The standard form of a number is a way of writing numbers that is commonly used in mathematics, especially in arithmetic and place value studies. To write the number 210 million, 64 thousands, and fifty in standard form, one combines these values considering their place values.
The value of 210 million is simply 210,000,000. The value of 64 thousands is 64,000, and the value of fifty is 50. When these are combined, we get:
210,000,000 (Two hundred and ten million)+ 64,000 (Sixty-four thousand)+ 50 (Fifty)Adding these together:
210,000,000 + 64,000 + 50 = 210,064,050
Therefore, the standard form of 210 million, 64 thousands, and fifty is 210,064,050.
Indicate the equation of the given line in standard form. The line that is the perpendicular bisector of the segment whose endpoints are R(-1,6) and S(5,5)
The equation of the perpendicular bisector of the segment with endpoints R(-1,6) and S(5,5) is found by calculating the midpoint, slope, and using the negative reciprocal for the perpendicular slope. It is then written in point-slope form and converted to standard form, resulting in 12x - 2y = 13.
Explanation:To find the equation of a line that is the perpendicular bisector of a segment with endpoints R(-1,6) and S(5,5), we need to take the following steps:
Determine the midpoint of the segment RS which will be a point on our bisector.Calculate the slope of the line segment RS.Find the negative reciprocal of the slope from step 2, which will give us the slope of our perpendicular bisector.Write the equation of the bisector line using the point-slope form and then convert it into standard form.The midpoint of RS is given by ((-1+5)/2, (6+5)/2) = (2, 5.5). The slope of RS is (5-6)/(5-(-1)) = -1/6. The negative reciprocal of -1/6 is 6. Thus, the slope of our bisector is 6.
Using the point-slope form with the midpoint, y - 5.5 = 6(x - 2). Expanding and rearranging to standard form, we get:
6x - y = 12 - 5.5 -> 6x - y = 6.5.
Multiplying through by 2 (to clear the decimal), we obtain:
12x - 2y = 13, which is the standard form equation of the perpendicular bisector of segment RS.

a candle maker has 4 1/2 pounds of wax. He wants to cut the wax into pieces that are 2/3 pound each. How many 2/3 pound pieces can he divide the wax into?
Answer:
[tex]6\frac{3}{4}[/tex] pieces.
Step-by-step explanation:
Let x represent number of pieces.
The amount of wax used in making x pieces would be [tex]\frac{2}{3}x[/tex].
We have been given that a candle maker has 4 1/2 pounds of wax. We can represent this information in an equation as:
[tex]\frac{2}{3}x=4\frac{1}{2}[/tex]
[tex]\frac{2}{3}x=\frac{9}{2}[/tex]
[tex]\frac{3}{2}*\frac{2}{3}x=\frac{3}{2}*\frac{9}{2}[/tex]
[tex]x=\frac{27}{4}[/tex]
[tex]x=6\frac{3}{4}[/tex]
Therefore, the candle maker can make [tex]6\frac{3}{4}[/tex] pieces.

One and two thirds times a right angle
Answer:
150 Degrees
Step-by-step explanation:
We have to find one and two third of a right angle.
That is we have to basically find [tex]1\displaystyle\frac{2}{3}\text{ of a right angle.}[/tex]
The measure of a right angle in degrees is 90 degrees.
[tex]1\displaystyle\frac{2}{3}\times 90[/tex]
We convert the mixed fraction into unlike fraction
[tex]\displaystyle\frac{5}{3}\times 90 = 150[/tex]
Thus, one and two third of a right angle is 150 degrees or [tex]150^\circ[/tex]
A restaurant uses 8 1/4 pounds of carrots to make 6 carrot cakes. Frank wants to use the same recipe. How many pounds of carrots does Frank need to make one carrot cake?
Frank needs [tex]\( \frac{11}{8} \)[/tex] pounds of carrots to make one carrot cake.
To find out how many pounds of carrots Frank needs to make one carrot cake, we first need to determine how many pounds of carrots are used per carrot cake in the original recipe.
Given that the restaurant uses 8(1)/(4) pounds of carrots to make 6 carrot cakes, we divide the total pounds of carrots by the number of cakes to find the amount per cake.
[tex]\( \text{Carrots per cake} = \frac{8\frac{1}{4}}{6} \)[/tex]
First, we convert the mixed number [tex]\(8\frac{1}{4}\)[/tex] to an improper fraction:
[tex]\(8\frac{1}{4} = \frac{(8 \times 4) + 1}{4} = \frac{33}{4}\)[/tex]
Then, divide by 6:
[tex]\( \frac{33}{4} \div 6 = \frac{33}{4} \times \frac{1}{6} = \frac{33}{24} = \frac{11}{8} \)[/tex]
So, Frank needs [tex]\( \frac{11}{8} \)[/tex] pounds of carrots to make one carrot cake.
