A 5-foot rope is cut into 2 pieces. Seven less than three times the length of the longer rope piece x is five times the length of the shorter piece, which is (5 − x) ft. Find the length of the longer rope piece x (in ft)
Let's call the length of the longer rope piece x and the length of the shorter rope piece y. We know that:
x + y = 5 (the total length of the rope is 5 feet)
And from the problem statement, we have:
3x - 7 = 5y
Now we can use the first equation to solve for y:
y = 5 - x
Substituting this expression for y into the second equation:
3x - 7 = 5(5 - x)
Expanding the right side:
3x - 7 = 25 - 5x
Adding 5x to both sides:
8x - 7 = 25
Adding 7 to both sides:
8x = 32
Dividing both sides by 8:
x = 4
So the length of the longer rope piece is 4 feet.

The total cost of an order of personalized invitations from a company includes the cost of each invitation, plus a one-time design fee. The cost of each invitation is the same regardless of how many invitations are ordered.
The invitation company provides the following examples to customers in order to estimate the total cost of an order:
50 invitations $298.50
500 invitations $2049
The total cost of an order is $900 if 50 invitations cost is $298.50
To calculate the cost of an order of personalized invitations, you would need to know the cost of each invitation and the one-time design fee.
Let calculate the cost of each invitation and the one-time design fee as follows:
50 Invitations: $298.50 / 50 = $5.97 per invitation
500 Invitations: $2049 / 500 = $4.098 per invitation
Design Fee: ($2049 - ($5.97 × 50)) / 500
= $3.90 one-time design fee
If you wanted to order 150 personalized invitations, the cost would be:
150 Invitations x $5.97 per invitation = $896.50
Plus one-time design fee of $3.90 = $890.40
Total cost = $896.50 + $3.90 = $900.

The percentage of decrease in the amount of land that Simon owns is 20.1%.
1,510 - 1,208 = 302
302 / 1,510 = 0.201
0.201 x 100 = 20.1%
Simon recently sold his old farmland, which was 1,510 acres in size, and purchased a new plot of land that is 1,208 acres in size. To calculate the percent of decrease in the amount of land that Simon owns, we subtract the new land size from the old land size and divide the result by the old land size. This number is then multiplied by 100 to get the percent of decrease. In this case, we subtract 1,208 from 1,510 to get 302. We then divide 302 by 1,510 to get 0.201. When we multiply 0.201 by 100, we get 20.1%, which is the percent of decrease in the amount of land that Simon owns now.

The first term of an A. P is 5 and the 10th term is 95 to find S10
The first term of an arithmetic progression is 5 and the 10th term is 95. The sum of the first 10 terms is 455.
The sum of the first 10 terms of an arithmetic progression (A.P.) can be found using the formula:
S_n = n/2 * (2a + (n-1)d)
where a is the first term, d is the common difference, and n is the number of terms.
Given that the first term is 5 and the 10th term is 95, we can find the common difference (d) using the formula:
a_n = a + (n-1)d
Plugging in n = 10 and a = 5, we get:
95 = 5 + (10 - 1)d
Solving for d, we get:
d = (95 - 5) / (10 - 1) = 9
Now that we know the common difference, we can find the sum of the first 10 terms:
S_10 = 10/2 * (2 * 5 + (10 - 1) * 9) = 10/2 * (10 + 81) = 10/2 * 91 = 455
So, the sum of the first 10 terms is 455.

The amount of wrapping paper used by Gavin to wrap a triangular prism box is 647.75 m².
What is a prism?
A prism is a polyhedron in geometry made up of an n-sided polygon basis, a second base that is a rigidly translated copy of the first base, and n additional faces that must all be parallelograms and connect the corresponding sides of the two bases.
The formula for area of rectangle is -
Area = length × breadth
The area of rectangle ABFG is -
Area = AB × BF
The value for line segment AB = 15 m
The value for line segment BF is -
BF = BC + CE + EF
BF = 14 + 7 + 15.65
BF = 36.65 m
So, the area of rectangle ABFG is -
Area = 15 × 36.65
Area = 549.75 m²
Now, the triangular prism has triangle part left.
The formula for area of triangle is -
Area = 1/2 × base × height
So, the area of triangle IJH is -
Area = 1/2 × IJ × JH
The value for line segment IJ = 14 m
The value for line segment JH = 7 m
So, the area of triangle IJH is -
Area = 1/2 × 14 × 7
Area = 49 m²
Since, there are two triangles (Δ IJH = Δ CDE ) so the area of total shape is -
Total area = Area of ABFG + 2(Area of Δ IJH)
Total area = 549.75 + 2(49)
Total area = 647.75 m²
Therefore, the area of triangular prism box is 647.75 m².

An athletic track is given in the figure.
The two straight parts are 80 m long.
The total length of the track is 400 m.
Find the radius of the curved part of the track
on both sides.
Subtract the length of the two straight parts
from the entire length of the track.
Answer:
The total length of the two straight parts is 80 m x 2 = 160 m.
So, the length of the curved part of the track is 400 m - 160 m = 240 m.
Let the radius of the curved part of the track be "r".
Since there are two curves, each of length "l", in the track, the total length of both curves is 2l.
The length of one curved part can be given by the formula:
l = 2πr, where π is pi (approximately equal to 3.14).
So, 2l = 2 x 2πr = 4πr.
Therefore, 4πr = 240 m.
Dividing both sides by 4π, we get:
r = 240 m / (4π) = 240 / (4 x 3.14) = 15 m.
Hence, the radius of the curved part of the track on both sides is 15 m.

Step-by-step explanation:
You want to know the descent rate of an airplane whose altitude is shown on a graph as being 1500 ft at 0 seconds and 0 ft at 180 seconds.
Rate of changeThe airplane descended 1500 feet over a period of 180 seconds. That rate of change is ...
(-1500 ft)/(180 s) ≈ -8.333 ft/s
The plane descends about 8 feet per second.
__
Additional comment
The slope of the line segment is the change in y divided by the change in x. For computing these changes, it is useful to consider points whose coordinates are obvious. Here, the y-intercept (1500 ft) and the x-intercept (180 seconds) are good choices.
The change in y from 1500 to 0 is a change of -1500. The change in x from 0 to 180 is a change of +180. The ratio of these changes is the slope, which is often designated by the letter m:
m = -1500/+180 = -25/3 = -8 1/3 . . . . . . about -8
The units of the slope are the ratio of the y-axis units to the x-axis units: feet/second.
The slope of -8 feet/second tells you the plane is descending about 8 feet per second.
A maintenance worker needs to wax a restaurant floor shaped like the image shown. A six-sided figure. There is a horizontal base of 33 feet then another horizontal base below it of 19 feet. The longest side is to the right and is 37 feet. The top is 28 feet. There is a perpendicular from the vertex of the top to the first base of 33 that is labeled 14 feet. If the wax cost $1.67 a square foot, how much will the wax cost to cover the floor? $832.50 $1,300.10 $1,664.99 $2,600.19
If the wax was priced at $1.67 per square foot, it would cost $1,664.99 to wax the entire floor. The right answer is C.
How to calculate the area of the floor?The floor is made up of a trapezoid and a rectangle.
The area of a trapezoid can be calculated as:
A = (b₁ + b₂)/2 x h
Where b₁ and b₂ are the lengths of the bases and h is the height.
The trapezoid is 14 feet tall, and its bases are 33 feet long and (28 - 19) or 9 feet wide. Thus, its area is:
A = (33 + 9)/2 x 14
A = 294 square feet
The rectangle is 37 feet tall with a 19-foot base. Thus, its area is:
A = 19 x 37
A = 703 square feet
The area of the triangle and trapezoid together make up the overall area of the figure.
A = 294 + 703
A = 997 square feet
Finally, to find the cost of the wax, we multiply the area by the cost per square foot:
Cost = 997 * $1.67
Cost = $1664.99

The width of standard television set is 16.8 inches.
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Because to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
We can solve this by using the Pythagorean theorem which is below:
[tex]a^{2} +b^{2} =c^{2}[/tex]
Or we can say
[tex]w^{2} +h^{2} =d^{2}[/tex]
w = width
h = height
d = diagonal measure
With that said, we know the height is .75 times the width so .75w. We also know d = 21, which is our diagonal measure.
w = don't know yet but need to find
h = .75w
d = 21
[tex]w^{2} +h^{2} =d^{2}[/tex]
[tex]w^{2} +(0.75w)^{2} =21^{2}[/tex]
1.5625 w^2 = 441
w^2 = 441/1.5625
