The ratio of female students to male students at a particular college is 3 to 2 If there are 3375 female students at the college, what is the total number of students at the college?
The total number of students at the college is (Simplify your answer)
Answer:
5,625
Step-by-step explanation:
divide 3375 by 3 and get 1125 now multiply that by two and get 2250. Add 3375 by 2250 to get 5625 students
Find the 19th term for the arithmetic sequence in which the 23rd term is 9 and the 11th term is -75 .
A) -19
B) -27
C) 27
D) 19
Answer:
A) -19
Step-by-step explanation:
Basics first:
An arithmetic sequence progresses with numbers being added or subtracted by a constant value.
After understanding that, as soon as we have any two values of the sequence we can find the constant value which is added or subtracted.
Look:
The 11th term is -75.
12 terms later (23th), the term is 4.
In other words, after "jumping" 12 terms, we went up 84 numbers (75 + 9)
To find the size of each "jump" we just divide the total number variation (84) by the number of jumps (12)
84/12 = 7
Now that we know the size of each jump, we can either jump 4 terms back from the 23rd term or jump 8 terms forward from the 11th term.
I will jump 4 terms back from the 23rd term:
19th term = 23rd term - 4 jumps
19th term = 9 - 4 * 7 //Remember that 7 is the jump size
19th term = 9 - 28
19th term = -19
Answer:
-19

shola earns #750 every month. if she spends 4/5 of her salary and saves the rest, how much does she save every month?
Answer:
250
Step-by-step explanation:
Amount she earns = 750
amount she spend = ⅘ of 750 = ⅘×750= 600
amount she saves = 750-600
Shola saves $150 every month.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is multiplied by 3, or 2 is added 3 times.
Given:
Shola earns $750 every month.
She spends 4/5 of her salary.
That means,
4/5 of $750.
And 4/5 of $750 = 4/5 x 750
= 4 x 150
= 600
She spends $650 per month.
Saved amount,
= $750 - $600
= $150
Therefore, $150 is her monthly savings.

I need to know exactly how to write "find the equation of the line below"
Answer:
y = -4/5x + 14/5
Step-by-step explanation:
Point (6,-2) and (-4,6)
Slope = (6- - 2) / (-4-6) = 8 / -10 = - 4/5
(The slope is negative because La línea is going downhill. Uphill is positive)
You can also find the slope in the graph: rise/run.
y-intersect (any point)
Point (6, -2) (any point)
y-Intercept: -2 - (-4/5)(6) = -2 + 24/5 = 14/5
Answer:
The general equation of the line is 4x+5y−14=0. the y=mx+c = y = -4/5x + 14/5
Step-by-step explanation:
Step 1) Write down your coordinates = ( -4, 6 ) and ( 6, -2 ) Step 2) find the gradient y2-y1/ x2 - x1 = -2-6 / 6--4 = -8/ 10 = -0.8 = - 4/5 = slope However in the point slope formula we need to use 3 identities and as (0, 2.4) is present coordinate for y intercept = (2.4 - 6) / (0- -4 )= -3.6/4 = - 0.9 and (-2 -2.4)/ (6-0) = -4.4/ 6 = - 0.733 we know y it crosses at 2.8 however it recognises it is a descending value (the paramount difference at 2nd point = -0.9 -0.7333= -0.1667 and widest point 0.2667 - 0.1667 = -1 would be our ascending parallel multiplier

y | 32, 72, 88, 112.
A) y=8x
B) y=8x+4
C) y=1/8x
9514 1404 393
Answer:
A) y = 8x
Step-by-step explanation:
For a proportional relationship ...
y = kx
the constant of proportionality k can be found from ...
k = y/x
From your table, we find ...
k = 32/4 = 8
So, the equation represented by the table is ...
y = 8x

An airline with two types of airplanes, P1 and P2, has contracted with a tour group to provide transportation for a minimum of 400 first class, 900 tourist class, and 1500 economy class passengers. For a certain trip, airplane P1 costs $10,000 to operate and can accommodate 20 first class, 50 tourist class, and 110 economy class passengers. Airplane P2 costs $8500 to operate and can accommodate 18 first class, 30 tourist class, and 44 economy class passengers. How many of each type of airplane should be used in order to minimize the operating cost?
The relationship between airplane 1 and airplane 2 is an illustration of objective function
14 of airplane 1 and 7 of airplane 2 should be used to minimize the operation cost
How to determine the number of each type of airplane?Represent P1 and P2 with x and y, respectively.
From the question, we ave have the following parameters:
x y Minimum
First class 20 18 400
Tourist 50 30 900
Economy 110 44 1500
Cost 10000 85000
So, the objective cost function to minimize would be:
C = 10000x + 8500y
And the constraints are:
20x + 18y ≥ 400
50x + 30y ≥ 900
110x + 44y ≥ 1500
x, y ≥ 0
Next, we plot the graphs of the constraints
From the graph (see attachment), we have the following feasible solutions
(x,y) = {(4.9,21.8), (8.5,12.7), (14,6.7)}
Substitute these values in the objective function.
C(5,22) = 10000 * 5 + 8500 * 22 = 237000
C(9,13) = 10000 * 9 + 8500 * 13 = 200500
C(14,7) = 10000 * 14 + 8500 * 7 = 199500
The minimum value is:
C(14,7) = 199500
Hence, 14 of airplane 1 and 7 of airplane 2 should be used to minimize the operation cost

Answer:
The third option
Explanation:
1: 9 cubes
-> Just counting the ones shown!
-> Not even anything, haha
2: 15 cubes
-> 5 * 3 = 15
-> Area of the bottom or top
3: 45 cubes
-> 15 * 3 = 45
-> Volume!
Volume is base times height (base = length times width) so the third option must be correct.

Answer:
No solution
One solution
Many solutions
One solution
Step-by-step explanation:
Let's use y = mx + b
m = coefficient (or slope)
b = constant ( or y-intercept)
If they have different y-intercepts but they're both rising the same amount there would be no solution because they would never cross
If the slope was different but the same y-intercept they would cross on the y-axis, making them have one solution
Equal coefficients and constants is correct, there would be infinite solutions
Different slopes and different y-intercepts would make them cross randomly one, so one solution

When a divisor divides the dividend exactly without leaving remainder then the divisor and quotient are

Answer:
The divisor is called a factor of the dividend.
Step-by-step explanation:
Hope this helps
(Brainliest is appreciated)
Answer:
If a divisor divides the dividend exactly and leaves no remainder, this divisor is also called a factor of that dividend. Therefore, all factors of a number are divisors, but not always all factors have to be factors of a number The factors of 8 are for example 1, 2, 4 and 8, because 8 can be divided exactly by 1, 2, 4, 8.
