Answer:
x = 55.06531425, or 55
Step-by-step explanation:
(x/68) = tan(39)
Set up your equation and rearrange it.68 * (x/68) = 68 * tan(39)
On the left side, with 68 * (x/68), the 68's cancel out and leave us with x.On the right side, with 68 * tan(39), we need to first solve for tan(39) and multiply it by 68. Continuing the right side, tan(39), when using a calculator, is 0.8097840332 (make sure your calculator is in degree mode), and when this is multiplied by 68, this makes 55.06531425.x = 55.06531425, or 55
Solve for x!Answer:
[tex]\huge\boxed{x \approx 55}[/tex]
Step-by-step explanation:
We need to note that this is an equation, in which we can solve for x.
[tex]tan(39) = \frac{x}{68}[/tex]
We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.
We now have the formula simplified down to [tex]0.81 = \frac{x}{68}[/tex]. To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.
We know have [tex]0.81 \cdot 68 = x[/tex]
[tex]0.81 \cdot 68 = 55.08 \approx 55[/tex], so x is approximately 55.

Add 5x to both sides of the equation.
Subtract 5x from both sides of the equation.
Add 10y to both sides of the equation.
Subtract 10y from both sides of the equation.
Answer:
Add 10y to both sides.
Step-by-step explanation:
Answer:
C) Add 10y to both sides of the equation
Step-by-step explanation:
We need to get x by itself.
So to make the 10y go to the other side, we add 10y to cancel it on the left, but move it to the right.
The equation now looks like this:
5x = 30 + 10y

Rachel has $5 in her savings account.
Option 1 will add $35 to her account each week.
Option 2 will double the amount of money in her account at the end of each week.
PART A:
Write a function in terms of x to model each option of saving.
PART B:
Rachel wants to have at least $700 in her account at the end of 8 weeks to go on a class trip. Determine which option will enable her to reach her goal. Justify your answer
Answer:
Step-by-step explanation:
Hello there! this problem will requite us to write 2 equations for both situations described.
firstly, the first equation will look something like this:
[tex]y=35x+5[/tex]
and the second equation will look like this:
y=5(1+100%)^x
If Rachel wants to save up 700 dollars in 8 weeks we can easily solve for which one will get her there by plugging in 700 for y and solving for x.
Solving for x in:
[tex]700=35x+5[/tex]
we find that this option will take a little over 19 weeks
Solving for x in:
700=5(1+100%)^x
we find that this option will take roughly 7.15 weeks

You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area

Nick and lisa are building a square pond in their backyard. They wish to put a 2 foot wide brick border around the outside. If the total area of the border and the pond is 196 square feet, find the length of the side of the pond.
Answer:
the length of the pond is 10 feet.
Step-by-step explanation:
The computation of the length of the pond side is shown below:
Let us assume the length of the pond side be x feet
Now the one side length with the brick border is x + 4
And, the pond is 196 square feet
Now the equation would be
(x + 4)^2 = 196
(x+4) = 14
x = 10
Therefore, the length of the pond is 10 feet.
The length of each side of the pond is required.
The length of the side of the pond is 10 feet.
AreaLet [tex]x[/tex] be the length of each side of the pool.
If the brick layer is 2 foot wide the size then 2 foot would be added to all the sides of the pool.
The length of each side would be [tex]x+2+2=x+4[/tex]
The area of the pool is [tex]196[/tex] square feet.
So,
[tex](x+4)^2=196\\\Rightarrow x+4=\sqrt{196}\\\Rightarrow x+4=\pm14\\\Rightarrow x=10,-18[/tex]
Since, negative number cannot be the length.
[tex]x=10\ \text{feet}[/tex]

Step-by-step explanation:
The y-intercept value in a given equation in the slope-intercept form, y = mx + b sis represented by b.
Thus, given the line [tex] y = \frac{-5x}{3} - \frac{8}{7} [/tex], the value of b (y-intercept) is represented as [tex] -\frac{8}{7} [/tex].
It is the value of y when x = 0.
