Answer:
Let's start by using the formula for the perimeter of a rectangle, which is:
P = 2L + 2W
where P is the perimeter, L is the length, and W is the width.
We're given that the perimeter is 78 meters, so we can write:
78 = 2L + 2W
Simplifying this equation, we get:
39 = L + W
We're also given that the length is 6 meters less than four times the width, so we can write:
L = 4W - 6
Now we can substitute this expression for L into the equation we got earlier:
39 = (4W - 6) + W
Simplifying this equation, we get:
39 = 5W - 6
Adding 6 to both sides, we get:
45 = 5W
Dividing both sides by 5, we get:
W = 9
So the width of the rectangle is 9 meters. We can use this value to find the length:
L = 4W - 6 = 4(9) - 6 = 30
So the length of the rectangle is 30 meters.

The probability of both getting a heart card and a red heart card is 1/4.
Given that there is a deck of 52-cards, we need to find the probability of getting a heart cards,
Probability shows how likely an event will happen.
P(E) = n(E) /n(S).
n(E) = Number of favorable outcomes of E.
n(S) = total number of possible outcomes of E.
No. of heart cards = 13
n(E) = 13
P (getting a card of heart) = no. of favorable outcomes/total no. of possible outcomes of E
= 13/52
= 1/4
Since heart card is red that means there are 13 heart cards which is red in color.
So, the probability of getting a red heart card = 13/52 = 1/4
Hence the probability of both getting a heart card and a red heart card is 1/4.

Identify the conic basic of x^2+xy+y^2+2x= -3
Answer:
The conic section basis of the equation x^2 + xy + y^2 + 2x = -3 can be determined by examining the coefficients of the x^2, xy, and y^2 terms.
To do this, we can start by completing the square for the quadratic terms in the equation:
x^2 + xy + y^2 + 2x = -3
(x^2 + 2x) + xy + y^2 = -3
(x + 1)^2 - 1 + xy + y^2 = -3
(x + 1)^2 + xy + y^2 = -2
Now, we can see that the coefficient of the xy term is positive, which indicates that the conic section is an ellipse. Specifically, this is a rotated ellipse because the x and y terms are not squared separately and have a non-zero coefficient.
Therefore, the conic section basis of the equation x^2 + xy + y^2 + 2x = -3 is a rotated ellipse.
Step-by-step explanation:
Answer:
Step-by-step explanation:
The given equation is:
x^2 + xy + y^2 + 2x = -3
To identify the conic basic of the equation, we need to check its discriminant, which is given by:
Δ = B^2 - 4AC
where A, B, and C are the coefficients of x^2, xy, and y^2 terms respectively.
In this case, A = 1, B = 1, and C = 1.
So,
Δ = B^2 - 4AC
= 1^2 - 4(1)(1)
= -3
Since the discriminant is negative, the given equation represents an ellipse.
4. The surface area of a cube is 486 in. Find the volume inside the cube but outside of
an inscribed sphere. Round to the nearest tenth.
The volume inside the cube but outside of an inscribed sphere is 231.6 cubic inches
Finding the volume inside the cube but outside of an inscribed sphere.From the question, we have the following parameters that can be used in our computation:
Cube volume = 486
This means that the side length of the cube is
l³ = 486
So, we have
l = 7.86
This represents the diameter of the sphere
So, the sphere volume is
V = 4/3πr³
So, we have
V = 4/3 * 22/7 * (7.86/2)³
Evaluate
V = 254.36
So, the required volume is
Volume = 486 - 254.36
Evaluate
Volume = 231.64
Approximate
Volume = 231.6
Hence, the volume inside the cube but outside of an inscribed sphere is 231.6 cubic inches

Will give brainly! Thank you!
Answer:
ΑΠSШЕЯ®
Step-by-step explanation:
The probability that all three students prefer to take some of their courses fully online can be found by multiplying the probabilities of each event together. Since each student has a 68% chance of preferring fully online courses, the probability that the first student prefers fully online courses is 0.68, the probability that the second student prefers fully online courses given that the first student does is also 0.68, and the probability that the third student prefers fully online courses given that the first two students do is also 0.68. Therefore, the probability that all three students prefer to take some of their courses fully online is 0.68 x 0.68 x 0.68 = 0.314. The probability is approximately 0.314 or 31.4%.

What is the range of the function f(x) = 3x + 2 over the interval -3 < x < 5?
Answer:
-7 < f(x) < 17
Step-by-step explanation:
f(x) = 3x + 2
The given domain is -3 < x < 5
If x = -3, f(x) = f(-3) = 3(-3) + 2 = -9 + 2 = -7
If x = 5, f(x) = f(5) = 3(5) + 2 = 15 + 2 = 17
The range of f(x) is the set of permissible values for f(x) for the given domain -3 < x < 5
Therefore range of f(x): -7 < f(x) < 17

The fixed cost is $275, and the variable cost for each product is $0.25.
The cost function can be written as: C(x) = 275 + 0.25x
How to solve(a) The linear cost function representing the cost C(x) (in $) to the vendor to produce x products can be determined by considering both the fixed cost (booth setup) and the variable cost (cost per product).
The fixed cost is $275, and the variable cost for each product is $0.25.
Therefore, the cost function can be written as:
C(x) = 275 + 0.25x
b. (b) R(x) = 3x, where x is the number of products sold and R(x) is the revenue in dollars.
(c) To break even, the cost must equal the revenue: 0.25x + 275 = 3x. Solving for x, we get x = 137.5. The vendor must produce and sell 138 products to break even.
(d) If 40 products are sold, the cost is C(40) = 0.25(40) + 275 = $285, and revenue is R(40) = 3(40) = $120. The vendor will lose money, as the cost is greater than the revenue.
