Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{100}[/tex] ( multiply both sides by 100 )
100 × tan35° = opp , that is
opp ≈ 100 × 0.7002 = 70.02
Thus height of tree = 70.02 + 5 = 75.02 ft
--------------------------------------------------------------------
Using the tangent ratio in the right triangle on the right.
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{25.17}{rope}[/tex] ( multiply both sides by rope )
rope × tan40° = 25.17 ( divide both sides by tan40° )
rope = [tex]\frac{25.17}{tan40}[/tex] = [tex]\frac{25.17}{0.839}[/tex] = 30 ft

The amount Ricky charges for his lawn service varies directly with the number of hours it takes to complete the job. If Ricky charges $112.50 for a 3-hour job, how much money would he charge for a 5-hour job?
Answers
The charge for a 5-hour job will be $187.5.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Ricky charges $112.50 for a 3-hour job.
Now,
Since, Ricky charges for 3 hour job = $112.50
Hence, The charges for 1 hour job = $112.50 / 3
= $37.5
So, The charges for 5 hour job = 5 x $37.5
= $187.5
Thus, The charge for a 5-hour job will be $187.5.

whats the distance between (1,2) and (4,-2)
Answers
Answer:
5 units
Step-by-step explanation:
Distance formula:
[tex]\sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]
Square root of those quantities. x2 and x1 mean the x values from one coordinate and the other, and the same goes for the y-coordinates. So y2-y1 represents (-2) - (2) and x2-x1 = (4) - (1). The answers you get (-4 and 3, respectively), now have to be squared, then added together. So (-4)^2 = 16 and (3)^2 = 9. Add 16 and 9 together you get 25. Final answer, you square root 25 and you get 5. Technically the square root of 25 is both positive and negative 5, but you cannot get a negative number for distance in this case (vectors are different).

Eight times the difference of a number and 2: 8(x - 2)
The sum of the number and 3: (x + 3)
Three times the sum of the number and 3: 3(x + 3)
Eight times the difference of a number and 2 is the same as 3 times the sum of the number and 3:
8(x - 2) = 3(x + 3)
Now just solve for x.
8x - 16 = 3x + 9

The amount of memory available on an iPhone seems like it doubles with each new version. If this is true, and the first version had 4 gigabytes of memory, how much memory does the 10th version have?
Answers
Answer:
40
Step-by-step explanation:
Multiply 10 by 4 which 4 represents the starting Iphone memory storage and then 10 represents the value of memory for the 10th model.
By solving the exponent, we find that the 10th version will have 2048 gigabytes of memory.

You are about to graph the linear equation y=1/4x+8 but you need to determine the scale of the x and y axes first. Select the best option for a scale for both the x-axis and y-axis (one of each). A) x scale of -5 to 5 B) x scale of -15 to 15 C) y scale of 0 to 15 D) y scale of -30 to 30 (10 POINTS AND BRAINLIST IF RIGHT WILL REPORT WRONG ANSWERS)
Answers
Answer:
B) x scale of -15 to 15
C) y scale of 0 to 15
Step-by-step explanation:
The change in y-value is 1/4 of the change in x-value, and the y-intercept is 8. That means a y-scale of -30 to 30 would not be well-utilized over a small range of x. (It would take an x-range of about 200 to make much use of that y-scale.)
An appropriate y-scale is one that has 8 near its middle. The corresponding x-scale is then roughly ±4 times half the y-scale. The closest choices are ...
-15 ≤ x ≤ 15 . . . . choice B
0 ≤ y ≤ 15 . . . . . . choice C

Your sister is selling Girl Scout cookies that cost $3.50 per box. Your family bought 6 boxes. How many more boxes of
cookies does your sister need to sell to raise $196?
Answers
Answer:
She needs $175.
Step-by-step explanation:
3.50 X 6= $21. (196-21=175)
So since she needs $196 and per box it would be $3.50 and 6 boxes is $21 total, she would need to sell 56 boxes total to get to her goal, but since her parents bought 6 boxes already she will only need 50 more.
