Explanation:
He has 90 feet of fencing overall. This is the perimeter of the rectangle as its the distance around all four sides.
Two of the opposite sides are the width = 15 ft. So we have 15+15 = 30 feet taken up and 90-30 = 60 feet left for the other two opposite sides to add to. Call each of those sides x
x+x = 60
2x = 60
x = 60/2
x = 30
The other side must be 30 feet long.
This rectangle is 30 by 15
perimeter = 30+15+30+15 = 45 + 45 = 90
which helps confirm we have the right answer
---------------
Or you can solve this way
P = 2*(L+W) is the perimeter of a rectangle with length L and width W
Plug in the perimeter P = 90 and the width W = 15. Solve for L
P = 2*(L+W)
90 = 2*(L+15)
2(L+15) = 90
L+15 = 90/2
L+15 = 45
L = 45-15
L = 30

The area of a rectangle is the product of its length and width. Both length and width are whole numbers. A rectangular poster has an area of 204 square inches. The width of the poster is greater than 10 inches and is prime. What is the width of the poster?
Answer:
17 inches.
Step-by-step explanation:
If the area of a rectangle is the product of its length and width, then;
Area of a rectangle = Length × Width
Given that the width of the poster is greater than 10 inches and is prime, this means and W>10
Area of the rectangle = 204in²
On substituting the values in the formula;
A = LW
204 = LW
Since W is greater than 10 and is prime, it can be between the prime numbers 11, 13 and 17. Note that L must be a whole number as well for any number to be the right answer we seek.
Let's test each values of the prime width that will give a length that is a whole number.
If W = 11
204 = 11×L
L = 204/11
L = 18.54
Since the length didn't give us a whole number, this means our width is not 11.
If W = 13
204 = L × 13
L = 204/13
L = 15.69
Also, we can see that the length is not also a whole number for the value of 13 as the prime width.
If W = 17
204 = L × 17
L = 204/17
L = 12
It can be seen that the length of the rectangle gave us a whole number when we used the prime width of 17, hence the width of the poster that is greater than 10 inches and is prime that makes both length and width to be a whole number is 17 inches.
Answer:17 inches

The depth of Sam's from the surface is 23 feet.
We are given that Ben and Sam are diving in a lake.
Ben and Sam are 14 feet below the surface.
But after a while, Ben spots Sam 9 feet directly below him.
We have to find sam's depth from the surface.
Let the depth at which both Ben and Sam were diving in the lake be X.
i.e X = 14 feet.
Let the depth of Sam from Ben be Y.
i.e Y = 9 feet.
Now Sam's depth from the surface would be:
= X + Y
= 14 + 9
= 23 feet.
Thus, the depth of Sam's from the surface is 23 feet.

Find an equation of the sphere that passes through the point (7, 1, −3) and has center (5, 6, 5).
Answer:
The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is [tex](x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93[/tex].
Step-by-step explanation:
Any sphere centered at [tex](h,k,s)[/tex] in an Euclidean space with a radius [tex]r[/tex] is represented by the following formula:
[tex](x-h)^{2} +(y-k)^{2}+(z-s)^{2} =r^{2}[/tex]
If [tex](x,y,z) = (7,1,-3)[/tex] and [tex](h,k, s) = (5,6,5)[/tex], the radius of the sphere is obtained:
[tex](7-5)^{2}+(1-6)^{2}+(-3-5)^{2} = r^{2}[/tex]
[tex]r^{2} = 93[/tex]
[tex]r = \sqrt{93}[/tex]
The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is [tex](x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93[/tex].

Tim has 74 socks, all in pairs. He has 1 more pair of white socks than black socks. How many individual socks of
each color does he have?
Answer:
36 individual white socks
38 individual black socks
Step-by-step explanation:
Pairs of socks = 74
He has 1 more pair of white socks than black socks.
Take the colors of the socks to be white and black
Let
Black pairs of socks = x
White pairs of socks = x + 1
Individual socks of each color
A pair of white socks = 2 Individual white socks
= 2white
A pair of black socks = 2 individual black socks
= 2black
Total pairs of socks = black pairs of socks + white pairs of socks
74 = 2white + 2black
74 = 2(x) + 2(x +1)
74 = 2x + 2x + 2
74 = 4x + 2
Subtract 2 from both sides
74 - 2 = 4x
72 = 4x
Divide both sides by 4
x = 72/4
= 18
x = 18
Pairs of white socks = x = 18
A pair of white socks = 2whites
= 2(18)
= 36 individual white socks
Pairs of black socks = x + 1
= 18 + 1
= 19 pairs
A pair of black socks = 2black
= 2(19)
= 38 individual black socks

Please Help ASAP it's my Math HW
Step-by-step explanation:
Use segment addition/subtraction:
GK = GJ − HJ + HK
GK = 2x + 5 − x + 4x − 1
GK = 5x + 4
If GK = 39, then the value of x is:
39 = 5x + 4
5x = 35
x = 7
Use segment subtraction to find GH and JK.
GH = GJ − HJ
GH = 2x + 5 − x
GH = x + 5
GH = 12
JK = HK − HJ
JK = 4x − 1 − x
JK = 3x − 1
JK = 20

[tex] \sf{7(r + 1) = 20.3}[/tex]
Distribute 7 through the parentheses
⇒[tex] \sf{7r + 7 = 20.3}[/tex]
Move 7 to right hand side and change it's sign
⇒[tex] \sf{7r = 20.3 - 7}[/tex]
Subtract 7 from 20.3
⇒[tex] \sf{7r = 13.3}[/tex]
Divide both sides of the equation by 7

Best regards!!
r is 1.9
Solve 7(r+1) = 20.3
Remove the brackets by dividing both sides by 7:
7(r+1) / 7 = 20.3 / 7
r + 1 = 2.9
Take 1 to the other side so that you can be left with r. When you do this, the sign will change from positive to negative:
r = 2.9 - 1
r = 1.9
r is therefore 1.9
