A certain college enrolled 29,000. It was reported 54 percent were female and 46 percent were male. In addition 61 percent were over the age of 25. How many students were in each category if 30 percent of those over the age if 25 were male

Answers

Answer:

Step-by-step explanation:

Total number of students = 29000

Number of female = 54% of 29000

54/100 x 29000 = 15660 students

Number of male = 46% of 2900

46/100 x 29000= 13340 students

61% of 29000 are over 25 years

61% of 29000= 61/100 x 29000

= 17690 students

Of the pupils over the age of 25, 30% are male

30% of 17690 students are male

30/100 x 7690 =5307 students

The number of females over the age of 25 = 17690 -5307

17690 - 5307 = 12383 female students.

Rearrange x= 3g + 2 to make g the subject

Answers

x = 3g + 2
3g + 2 = x
3g = x - 2
g = (x - 2)/3

Answer:

g = 1/3 x - 2/3

Step-by-step explanation:

x =3g + 2

Switch sides:

3g + 2 = x

Take away 2 from both sides:

3g = x - 2

Divide both sides by 3:

g = 1/3 x - 2/3

Alicia purchased h half gallons of ice cream for 3.50 each p packages of ice cream cones for 2.50 each she purchased 14 items and spent 43$ which system of equations could be used to determine how many of each item Alicia purchased

Answers

Answer:

H + P = 14

3.50H + 2.50P = 43

Step-by-step explanation:

Given that

H denotes half gallons of ice cream

P denotes packages of ice cream cones

Now  

H + P = 14

And,  

3.50H + 2.50P = 43

So, the systems of equations would be

H + P = 14

3.50H + 2.50P = 43

Answer:

c=20 e=114 d=46 dec=180

Step-by-step explanation:

y=5

Answer:

m∠C = 32°

m∠D = 82°

m∠DEC = 66°

Step-by-step explanation:

Exterior Angle Theorem says that the degree measure that with an angle forms a straight line (Ex. Angle DEF in the picture) is equal to the sum of the two other angles in the triangle. This means that the measure of angle DEF is equal to the measure of angle DCE plus the measure of angle CDE. This would mean that 9y + 1 + 3y + 5 = 114, meaning that 12y + 6 = 114, which means that 12y = 108, which means that y = 9. If we plug 9 in for all of these values, we get that angle D is 9 * 9 + 1, which is 82 and that angle C is 3 * 9 + 5, which is 32. Next, we know that the sum of angles in a triangle is 180, so we subtract 32 and 82 from 180 to find the measure of angle DEC, and this is 66 degrees.

What is the greatest surface area of a rectangular solid that can be built from 16 identical unit cubes?

Answers

Answer and explanation:

The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.

We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes

Surface area is therefore 16×6a²

Sarah drinks 30 liters of water on weekdays and 12 liters of water on weekends. How many liters of water does Sarah drink per day?

Answers

Easy, 6

30 divided by 5 equals 6

12 divided by 2 equals 6

Answer:

6 liters per day

Step-by-step explanation:

Hi there!

We know that Sarah drinks 30 liters on weekdays. There are 5 days in a week not including the weekends. You have to divide 30 liters by 5 to get the per day amount. 30 divided by 5 is 6. This means that Sarah drinks 6 liters per day. This is accurate because when you go on to check the amount of water she drinks on weekends, you know there are two days in a weekend, and you know she drinks a total of 12 liters during the weekend, so 6 liters multiplied by those two days is equal to 12.

Really hope this helps :)
