One side of a rectangle is 9 feet shorter than three times another side. Find the length of the shorte
ide if we also know that the perimeter of the rectangle is 126 feet.
F=?
The shorter side of the rectangle is 18 feet.
How to Find the Perimeter of a Rectangle?Perimeter of a rectangle = 2(l + w), where w is the width of the rectangle and l is its length.
Given the following:
Another side of the rectangle = width = w
One side of the rectangle = length = 3w - 9
Perimeter of the rectangle = 126 feet
Therefore:
2(3w - 9 + w) = 126
2(4w - 9) = 126
8w - 18 = 126
8w = 126 + 18
8w = 144
8w/8 = 144/8
w = 18
One side of the rectangle = 3w - 9 = 3(18) - 9 = 45
Therefore, the shorter side of the rectangle is 18 feet.

The expression that is equivalent to the given expression (10^−2 • 4^5)^−2 is 10^(4) • 4^(−10)
How to determine the expression that is equivalent to the given expression?The expression is given as
(10−2 • 45)−2
Rewrite the above expression properly as follows:
(10^−2 • 4^5)^−2
Apply the power rule of indices
So, we have
(10^−2 • 4^5)^−2 = 10^(−2 * −2) • 4^(−2 * 5)
Evaluate the product of powers
So, we have
(10^−2 • 4^5)^−2 = 10^(4) • 4^(−10)
Hence, the expression that is equivalent to the given expression (10^−2 • 4^5)^−2 is 10^(4) • 4^(−10)

Find the coordinates of the point 3/10
of the way from A to B.
The coordinates of the point 3/10 of the way from a to b is (-0.3, -6.3)
How to determine the coordinates of the point?The given parameters are:
the coordinates of b is (9,7) the coordinates of a is (-4,-6)The position of the point is given as:
Location = 3/10
Express as ratio
m ; n = 3 : 10 - 3
This gives
m ; n = 3 : 7
The coordinates of the point are then calculated as:
Point = Location * (mx2 + nx1, my2 + ny1)
This gives
Point = 3/10 * (3 * 9 + 7 * -4, 3 * 7 + 7 * -6)
Evaluate
Point = 3/10 * (-1, -21)
This gives
Point = (-0.3, -6.3)

Sacha picked some apples from a tree in her garden. She then gave some to her friends. To her
first friend, she gave half the apples she had, plus 2 more. To her second friend, she gave half the apples she had left, plus 2 more. And she did the same thing for her third friend. After giving away all these apples, she had 1 apple left. Find how many apples she originally pick from the tree.
Step-by-step explanation:
x = apples picked from the tree
x1 = x/2 + 2
x2 = (x - x1)/2 + 2 = (x - (x/2 + 2))/2 + 2 =
= (x - x/2 - 2)/2 + 2 = (x/2 - 2)/2 + 2 =
= x/4 - 1 + 2 = x/4 + 1
x3 = (x - x1 - x2)/2 + 2 = (x - (x/2 + 2) - (x/4 + 1))/2 + 2 =
= (x - x/2 - 2 - x/4 - 1)/2 + 2 =
= (x/4 - 3)/2 + 2 = x/8 - 3/2 + 2 = x/8 + 1/2
x - x1 - x2 - x3 = 1
x - x/2 - 2 - x/4 - 1 - x/8 - 1/2 = 1
x/8 - 3 - 1/2 = 1
x/8 = 4 1/2 = 9/2
x = 9×8/2 = 9×4 = 36
she had originally 36 apples
x1 = 20

Find the length indicated FIND IK HELP
Answer:
Here is the answer, let me know if I did it wrong.
Answer:
IK = 13 and x = - 12
Step-by-step explanation:
Let's write down each segment and if available express it in terms of x which has to be determined in order to find length of segment IK
We have IK = x + 25 (to be determined)
JK = 2x + 30 (1)
KL (unknown)
IL = x + 34 (2)
JL = 15 (3)
The entire segment
IL = IJ + JL
Substituting for JL = 15 we get IL = IJ + 15
But we are given IL = x + 34
IJ + 15 = x + 34
IJ = x + 34 -15 = x + 19 (4)
IK = IJ + JK
Substituting for IJ = x + 19 from equation (4) and JK = 2x + 30 from equation (1) we get IJ + IK = x + 19 + 2x + 30 = 3x + 49
But we are given that IK = x + 25
So
3x + 49 = x + 25
Moving x from the RHS to the LHS and 49 from the LHS to the RHS we get
3x-x = 25 - 49
2x = -24
x = -12
IK = -12 + 25 = 13
We can verify this by finding the lengths of each segment and seeing they are consistent
We have
IJ = x + 19 = -12 + 19 = 7
JK = 2x + 30 = 2(-12) + 30 = -24 + 30 = 6
IL = x + 34 = -12 + 34 = -23
We also have the fact that JK + KL = JL = 15
Substituting for JK we get
6 + KL = 15
KL = 15-6=9
Total segment length = 7+6 + 9 = 22
x + 34 = -12 + 34 = 22
So it is consistent

When only Friend A and Friend B are working, they make 4 mums per hour. How many mums can be created by each friend every hour?
The number of mums created every hour by each friend are:
Friend A working every hour creates 1 mum, Friend B working every hour creates 3 mums, and Friend C working every hour creates 2 mumsHow to find the number of mum created per hour by each friendGiven data
Friend A, Friend B, and Friend C working = 6 mums per hour
Friend B and Friend C working = 5 mums per hour
Friend A and Friend B are working = 4 mums per hour
A + B + C = 6 equation 1
B + C = 5 equation 2
A + B = 4 equation 3
from equation 2, make C the subject of the formula
B + C = 5
C = 5 - B
from equation 3, make A the subject of the formula
A + B = 4
A = 4 - B
substitute A and C into equation 1 to get
A + B + C = 6
4 - B + B + 5 - B = 6
4 + 5 - B = 6
9 - B = 6
-B = 6 - 9
-B = -3
B = 3
substituting B for A we have

A blogger found that the number of visits to her Web site increases 5.6% annually. The Web site had 80,000
visits this year. Write an exponential model to represent this situation. By what percent does the number of
visits increase daily? Explain how you found the daily rate.
f(t) = 80,00[tex](1+ 0.056)^{t}[/tex] is the exponential function that represents the model. The number of visits increase by 0.015% daily.
Here, we are given that a blogger found that the number of visits to her Web site increases 5.6% annually.
The exponential function is given as-
Final value = initial value [tex](1 + r)^{t}[/tex]
where r = rate of change
and t = time
here, r = 5.6%
r = 0.056
Further, the Web site had 80,000 visits this year ⇒ initial value = 80,000
Thus, we can get the following function-
f(t) = 80,00[tex](1+ 0.056)^{t}[/tex]
where f(t) represents the views after t years.
Now, since we are given that the views increase by 5.6% in 1 year
and 1 year = 365 days
⇒ daily rate = 5.6/365
= 0.015
Thus, the number of visits increase by 0.015% daily.

What is an equation of the line that passes through the point (-2,-4) and is parallel to the line 5x-2y=6
5x-2y = -2 is the equation of line that passes through the point (-2,-4) and is parallel to the line 5x-2y=6.
Given that, (x₁, y₁) = (-2, -4) and parallel to 5x - 2y = 6
Let's calculate the slope of 5x - 2y = 6
Rewrite the equation in y = mx + c form
5x - 2y = 6
⇒ -2y = 6 - 5x
⇒ -y = 3 - 5/2x
⇒ y = -3 + 5/2x
⇒ y = 5/2x - 3
Thus, the slope (m) = 5/2
As the line is parallel to 5x - 2y = 6 it will have a slope of 5/2.
The point-slope formula states (y - y₁) = m(x - x₁)
Now, substituting the value of m = 5/2 and (x₁, y₁) = (-2, -4), we get
(y - y₁) = m(x - x₁)
⇒ (y - (-4)) = 5/2(x - (-2))
⇒ (y+4) = 5/2(x+2)
⇒ 2(y+4) = 5(x+2)
⇒ 2y+8 = 5x+10
⇒ 5x-2y+10-8 = 0
⇒ 5x-2y+2 = 0
⇒ 5x-2y = -2
Hence, the line that passes through the point (-2,-4) and is parallel to the line 5x-2y=6 is 5x-2y = -2.
Therefore, 5x-2y = -2 is the required answer.
