Answer:
Combined
Step-by-step explanation:
Explore the relationship between the general forms of variation :
Direct Variation :
x varies directly as y ; x = kx
Inverse Variation :
x varies inversely as y ; x = k/x
Joint : x varies jointly as y and Z ; x = kxz
combined :
x varies directly as y and inversely as z ; x = kx * 1/ ; x = kx/z
Where k is the proportionality constant.
In the equation given above :
We have a combination of joint and inverse variation : V = 5ng
V varies jointly as n and t and inversely as m
V α k * n * t * 1 / m
V = Knt /m
Where, k is proportionality constant.

Is 5x - 7= 18 and 7x + 5=40 both equivalent, and what’s the value of x?
Answer: 5
Step-by-step explanation:
1. 5x - 7 = 15
5x = 25
x = 5
2. 7x + 5 = 40
7x = 35
x = 5
h(s) = (s^4-5)^2 derivative
If h(s) = (s ⁴ - 5)², then by the chain and power rule,
h'(s) = 2 (s ⁴ - 5) • (s ⁴ - 5)'
By the power rule,
(s ⁴ - 5)' = 4s ³
so that
h'(s) = 8s ³ (s ⁴ - 5)
… = 8s ⁷ - 40s ³

Answer:
Step-by-step explanation:
Between the two diagrams, you have an isosceles triangle
The base is 26 on the triangle on the right, and 20 on the left triangle.
So that's the ratio used to create the proportion
26/20 = x/26 cross multiply
20x = 26 * 26
20x = 676 Divide by 20
x = 676 / 20
x = 33.8

CORRECT ANSWER WILL BE BRAINLIEST+20 POINTS!!!!! For the figures below, assume they are made of semicircles, quarter circles, and squares. For each shape, find the area and perimeter. Give your answer as a completely simplified exact value in terms of π (no approximations).
Answer:
First Picture:
Area = 36pi - 72
Perimeter = 6pi + sqrt(288)
Second Picture:
Area = 576
Perimeter = 48pi + 48
Step-by-step explanation:
First Picture:
Area:
To find the area of the first picture, we need to find the are of quarter of a circle and the area of the triangle (notice we divide by 4 for the circle cause its a quarter of a full circle) .
A of triangle = (b * h )/2 = (12^2)/2 = 72
A of quarter of circle = (r^2 * pi)/4 = (144*pi*)/4 = 36pi
If you subtract the circle by the triangle, you get the shaded area:
36pi - 72
Perimeter:
We need to find the curve and the hypotenuse of our triangle (again, since we only have a quarter of a circle we must divide our perimeter by 4).
hypotenuse = sqrt (12^2 + 12^2) = sqrt (288)
curve = (2*pi*r) / 4 = 24pi / 4 = 6pi
So if we add these, we should have the perimeter
6pi + sqrt (288)
Second Picture:
Area:
we just need to know the area of the square because the semi circles cancel out cause they have the same diameter.
square = 24 * 24 = 576
576
Perimeter:
we need the perimeter of a semicircle and the sides of the square.
semi circle = d*pi = 24pi
sides of square = 24
Now our sum is...
(semi circle ) 2 + (sides of square) 2 = answer
Because our perimeter consists of two semicircles and two sides of the square. And this gives us...
answer = (24pi) 2 + (24) 2 = 48pi + 48
48pi + 48
The military academy is placing cadets in rows for the parade. All rows must have the same number of cadets. If A company has 60 cadets and B company has 72 cadets, what is the greatest number of cadets who can be in each row? A. 4 B. 6 C. 12 D. 15
Answer:
C. 12
Step-by-step explanation:
All rows must have the same number of cadets. If A company has 60 cadets and B company has 72 cadets
We find the factors of 60 and 70
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Then the greatest common factor is 12.
Therefore, the greatest number of cadets who can be in each row is 12 cadets.
Option C is the correct option.
Answer:

what is 6x+7y=4x+4y6x+7y=4x+4y
we have
6x+7y=4x+4y
we figure out that
the solution is ----> (x,-4)
substitute the value of y=-4 in the equation
6x+7*(-4)=4x+4*(-4)
6x-28=4x-16
Combine like terms
6x-4x=28-16
2x=12
x=12/2
x=6
So the the missing value is x=6.

Morgan surveyed 260 of the students in her school about their favorite color. 65% said their favorite color was red. How many students' favorite color was red?
Answer:
169 students
Step-by-step explanation:
From the above question:
Total number of students surveyed = 260
Percentage of students that their favorite colour is red = 65%
Hence: The number of students that their favorite color is red is calculated as:
= 65% × 260
= 65/100 × 260 students
= 169 students
The number of students that their favorite color is red is 169 students
An enclosed area is designed using one existing wall, and 72m of fence material. What is the maximum area of the enclosure?
Answer:
The maximum area possible is 648 squared meters.
Step-by-step explanation:
Let the length of the existing wall be [tex]\ell[/tex].
And let the width of the fence be [tex]w[/tex].
The area of the enclosure will be given by:
[tex]A=w\ell[/tex]
Since the area is bounded by one existing wall, the perimeter (the 72 meters of fencing material) will only be:
[tex]72=2w+\ell[/tex]
We want to maximize the area.
From the perimeter, we can subtract 2w from both sides to obtain:
[tex]\ell=72-2w[/tex]
Substituting this for our area formula, we acquire:
[tex]A=w(72-2w)[/tex]
This is now a quadratic. Recall that the maximum value of a quadratic always occurs at its vertex.
We can distribute:
[tex]A=-2w^2+72w[/tex]
Find the vertex of the quadratic. Using the vertex formula, we acquire that:
[tex]\displaystyle w=-\frac{b}{2a}=-\frac{(72)}{2(-2)}=18[/tex]
So, the maximum area is:
[tex]A=-2(18)^2+72(18)=648\text{ meters}^2[/tex]

On a certain hot summer's day, 340 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $677.00. How many children and how many adults swam at the public pool that day?
Answer:
Number of children = x = 88
Number of Adults = y = 252
Step-by-step explanation:
Let us represent:
Number of children = x
Number of Adults = y
On a certain hot summer's day, 340 people used the public swimming pool.
Hence:
x + y = 340..... Equation 1
x = 340 - y
The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $677.00.
$1.25 × x + $2.25 × y =$ 677
1.25x + 2.25y = 677..... Equation 2
Let us substitute: 340 - y for x in Equation 2
1.25(340 - y) + 2.25y = 677
= 425 - 1.25y + 2.25y = 677
Collect like terms
- 1.25y + 2.25y = 677 - 425
1y = 252
y = 252
Solving for x
x = 340 - y
x = 340 - 252
x = 88
Therefore the number of children and adults that swam at the public pool that day are: 88 children and 252 Adults.e
