If 48% of the students in a certain college are female and there are 2,400 female students, how many students are male?
Answer:
2,600 male students
Step-by-step explanation:
[tex]\frac{2,400}{0.48} = 5,000[/tex]
There are 5,000 students in total.
Since 2,400 of them are female, the remaining students must be male.
5,000 - 2,400 = 2,600 male students
Kiran has $100 saved in a bank account. (The account doesn’t earn interest.) He asked Clare to help him figure out how much he could take out each month if he needs to have at least $25 in the account a year from now.
He could take out $6.25 for each month and at the end $25 also left in his account.
What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the data given in the question,
The total amount Kiran is having in the bank = $100
He needs to have at least $25 in the account at the end of the year.
So, the money he can spend in a year = $100 - $25 = $75
1 year = 12 months
So, the amount of money spent per month will be,
75/12 = $6.25

Two length of two sides of a right triangle are given. Find the length of the third side. Round to the nearest tenth If necessary.
Leg: 28m; hypotenuse: 37m
Answer:
24.2
Step-by-step explanation:
Leg: 28m
Hypotenuse: 37m
To find the missing leg, use the following formula:
b = √[tex]c^{2} - a^{2}[/tex]
b = √[tex]37^{2} - 28^{2}[/tex]
b = √1369 - 784
b = √585
b = 24.18677
Round to the nearest tenth
24.18677 = 24.2
Which planet in the chart is most likely Earth? Yeah
Does somone no the answer
Answer:
Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:

Angle O=64
Side m=7.3159882(rounded if needed)
Side n=16.68902(round if needed)
We are given
Angle M which equal 26.
Angle N equals 90 degrees
Side MN which equal 15.
We are asked to find all the missing elements of the triangle.
Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.
[tex]90 + 26 + x = 180[/tex]
[tex]116 + x = 180[/tex]
[tex]x = 64[/tex]
Angle O=64 degrees
We can find side m by doing law of sines.
[tex] \frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) } [/tex]
[tex] \frac{on}{ \sin(26) } = \frac{15}{ \sin(64) } [/tex]
[tex]on = \frac{15}{ \sin(64) } \times \sin(26) [/tex]
which is 7.315(round if neeeded).
We can find side n using pythagorean theorem,
[tex] {15}^{2} + {7.3}^{2} = {n}^{2} [/tex]
[tex]225 + 53.29 = {n}^{2} [/tex]
[tex] \sqrt{278.29} [/tex]
Side n=16.689(round if needed)
HELP FIND VALUE OF X
Answer:
72
Step-by-step explanation:
5a = 540 [ all interior angles r equal to 540 as "(n-2)x 180 (Interior ____________________________________________angle poperty )]
a= 540/5 = 108 (one interior angle)
x + a = 180 (linear pair)
x= 180 - a
x = 180 - 108 = 72
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Another way ::
Sum of Exterior angle = 360 (exterior angle property)
One exterior angle = x = 360 / 5 = 72 ( 360 by the number of sides )

Nick is on his school's swim team. During his 2-week winter break, he swims 30 laps each week to stay in shape. If each lap is 25 yards, how many feet does he swim during his winter break? Feet
Answer:
3900 feet
Step-by-step explanation:
Steps to answer this question
We are to convert yards to feet Multiply laps sum by two to determine the number of laps he swam in two weeksthen multiply figures gotten from 1 and 21 yard = 3 foot
25 yards = 25 x 3 = 65 foot
total yards swam = 30 x 2 = 60
60 x 65 = 3900
Solve for x, rounding to the nearest hundredth.

Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?
Answer:
(a) The possible dimensions are:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
(b): Patio with greatest and the least perimeter
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
Step-by-step explanation:
Given
[tex]Tiles = 72[/tex]
Solving (a): Possible rectangular models
To do this, we simply list out the possible factor pairs of 72.
So, we have:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
Solving (a): Models with the least and the greatest perimeter
Perimeter (P) is calculated using:
[tex]P = 2 * (L + W)[/tex]
So:
1 unit by 72 units;
[tex]P = 2 *(1 + 72) = 146 units[/tex]
2 units by 36 units;
[tex]P = 2 *(2 + 36) = 76 units[/tex]
3 units by 24 units;
[tex]P = 2 *(3 + 24) = 54 units[/tex]
4 units by 18 units;
[tex]P = 2 *(4 + 18) = 44 units[/tex]
6 units by 12 units;
[tex]P = 2 *(6 + 12) = 36 units[/tex]
8 units by 9 units
[tex]P = 2 *(8 + 9) = 34 units[/tex]
From the calculations above:
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9

Answer:
x = 3.6
Step-by-step explanation:
It can be helpful to write down corresponding sides and their measures.
AB = 5, PQ = 6
BC = 3, QR = x
CD = 2, RS = 2.4
DA = 4, SP = 4.8
Then you can look for easy ways to find x. You can tell from this table that all of the values in PQRS are 6/5 = 1.2 times the corresponding values in ABCD.
Then ...
QR = 1.2×BC = 1.2×3
QR = x = 3.6
_____
Other ways you can figure x are ...
x/BC = PQ/AB
x = (BC)(PQ/AB) = 3(6/5) = 3.6 . . . . the method we used
__
x/RS = BC/CD
x = 2.4(3/2) = 3.6
__
x/SP = BC/DA
x = 4.8(3/4) = 3.6

2. The area of a square is represented by the expression 16m2 - 40m + 25 square units. write the expression to represent the dimensions for each side. Explain what process you use. Justify your answer.
Answer:
Each side = 4m-5
Step-by-step explanation:
16m2 - 40m + 25
factor:
(4m - 5)(4m - 5)
Each side = 4m-5
Answer:
The expression for each side = 4m - 5.
Step-by-step explanation:
We need to factor the expression for the area. As the figure is a square both factors should be identical.
16m^2 - 40m + 25:
16m^2 and 25 are both perfect squares so looks like the factors are
(4m - 5)(4m - 5)
The signs are negative because the middle term is - 40m.
If we expand the factors we get:
4m*4m - 5*4m - 5*4m -5*-5
16m^2 - 20m - 20m + 25
= 16m^2 - 40m + 25 which is the original expression, so this confirms our result.

Determine the length of the line segment with the end points at (9, 6) and (-12, 6).
Answer:
Step-by-step explanation:
You are given two points whose y values are the same. There is no need to use the distance formula. The x values alone will give you the length of the line.
to get to the y axis you have to go 12 units to the right.
To get from the y axis to 9, you have to go 9 more units to the right.
The total is 9 + 12 = 21
If you insist to see this done with the formula, it would look like this.
d = sqrt( y2 - y1)^2 + (x2 - x1)^2 )
y2 = 6
y1 = 6
x2 = -12
x1 = 9
d = sqrt ( (6 - 6)^2 + (-12 - 9)^2 )
d = sqrt( 0 + ( -21 )^2 )
d = sqrt( 441)
d = 21 the same thing you got just be reasoning it out.
The first method works only if either both xs are the same or both ys are the same.
Monique bought 3 boxes of cereal at the grocery store. Each box of cereal costs c dollars. Which equation represents the total amount of money, t, Monique spent on cereal?
Answer:
3c = t
Step-by-step explanation:
3 cereal boxes is 3c and the total is t. so 3c = t
Answer:
3c = t
3 is the amount of boxes, c is the money, therefore, it is 3c=t, which means c times the number of boxes equals t

priced at $875 but discounted 60%. If sales tax in Belleville is 10%, what was the total cost?
Answer:
$385
Step-by-step explanation:
60% of $875 = $525
$875 - $525 = $350
10% of $350 = $35
