A surveyor took the following measurements from two irregularly shaped pieces of land. Some of the lengths and angle measures are missing. Find all missing lengths and angle measures. Round lengths to the nearest tenth and angle measures to the nearest minute
To find the width of the river, use trigonometry and the tangent function. The width of the river is approximately 67.1 meters.
Explanation:To find the width of the river, we can use trigonometry. The surveyor measured an angle of 35° from the baseline to the tree on the opposite bank. We know the distance along the river is 100 m. Let's denote the width of the river as 'x'.
We can use the tangent function to solve for 'x'. The tangent of the angle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is 'x' (the width of the river) and the adjacent side is 100 m (the distance along the river).
So, the equation becomes:
tan(35°) = x/100
To find the value of 'x', we can multiply both sides by 100:
x = 100 * tan(35°)
Using a calculator, we can find that x is approximately 67.1 m. Therefore, the width of the river is approximately 67.1 meters.

6^2=36
The conversion of the expression 6^2=36 into logarithmic form results in log6(36) = 2. This method involves identifying the base (6), the exponent (2), and the result (36) in the original exponential equation.
Explanation:In mathematics, you can interchange between an exponential form and a logarithmic form. Your given expression is 6^2=36, which is in exponential form.
To change this into logarithmic form, identify the base (which is 6 in this case), the exponent (which is 2), and the result (which is 36). The logarithmic form of the equation would then be 'log base 6 of 36 is 2'.
So, written in the usual mathematical notation, your answer would be log6(36) = 2. Here, 'log' stands for logarithm; the number following 'log' (6 in this case) is the base, the term within parentheses (36 in this case) is the number we're taking log of, and '2' is the value of the logarithm.

Cell phones can weigh as little as 2 ounces. How many pounds can the cell phone weigh?
A cell phone weighing 2 ounces translates to 0.125 pounds, since there are 16 ounces in one pound.
Explanation:Cell phones can weigh as little as 2 ounces. The first step in determining how much a cell phone can weigh in pounds is to know the conversion factor between ounces and pounds. Since there are 16 ounces in one pound, you can divide the weight of the cell phone in ounces by 16 to convert it to pounds. For a cell phone that weighs 2 ounces:
Divide the weight in ounces by 16 to convert to pounds: 2 ounces ÷ 16 = 0.125 pounds.Therefore, a cell phone that weighs 2 ounces is equivalent to 0.125 pounds.

Answer:
f(x) = 15x + 25; f(6) = 115
Step-by-step explanation:
the flat rate of $25 will be the y-intercept and the slope will be $15. since u are charged $115, plug that in for f(x) and solve for x. so the right answer is
f(x) = 15x + 25; f(6) = 115
The top of a 22-foot ladder rests against the top of an 18-foot wall. If the base of the ladder is on the same ground level as that of wall, what angle does the ladder form with the ground? Express your solution to the nearest degree.
Answer:
Step-by-step explanation:
Given that The top of a 22-foot ladder rests against the top of an 18-foot wall.
The ladder, the wall and the floor together make a right angled triangle with hypotenuse as ladder.
Thus we have a right triangle with hypotenuse = 22 ft
and the side of the wall = 18
The required angle is the angle the ladder form with the ground.
Hence we have if x is the angle
[tex]sin x =\frac{Opposite}{Hypotenuse} =\frac{18}{22}[/tex]
From this we can find the angle X
X = sin inverse of 18/22
X=54.9
Round it off to X=55 degrees

b.100, 140, 150, 160, 200 10, 50, 60, 70, 110
c.10, 16, 18, 20, 22, 28 48, 56, 58, 60, 62, 70
a. Set 2 has larger standard deviation.
b. Set 1 and set 2 have same standard deviation.
c. Set 2 has larger standard deviation.
a. Set 1: 4, 7, 7, 7, 10
Set 2: 4, 6, 7, 8, 10
It seems like Set 2 might have a larger standard deviation because the numbers are more spread out from the mean (which appears to be around 7).
The set 3 has larger standard deviation.
For Set 1:
Mean = (4 + 7 + 7 + 7 + 10) / 5
= 7
Standard Deviation = ([tex]\sqrt{\frac{(4-7)^2 + (7-7)^2 + (7-7)^2 + (7-7)^2 + (10-7)^2)}{5}[/tex]]
= 1.89
For Set 2:
Mean = (4 + 6 + 7 + 8 + 10) / 5
=7
Standard Deviation = ([tex]\sqrt{\frac{(4-7)^2 + (6-7)^2 + (7-7)^2 + (8-7)^2 + (10-7)^2)}{5}[/tex]]
= 2
Hence, set 2 has larger standard deviation.
b. Set 1: 100, 140, 150, 160, 200
Set 2: 10, 50, 60, 70, 110
Here, Set 1 seems to have same standard deviation as set 2.
For set 1:
Mean = (100 + 140 + 150 + 160 + 200) / 5 = 150
Standard Deviation =[tex]\sqrt{\frac{(100-150)^2 + (140-150)^2 + (150-150)^2 + (160-150)^2 + (200-150)^2)}{5}}[/tex]
= 32.24
For set 2:
Mean = (10 + 50 + 60 + 70 + 110) / 5
= 60
Standard Deviation = [tex]\sqrt{\frac{(10-60)^2 + (50-60)^2 + (60-60)^2 + (70-60)^2 + (110-60)^2)}{5}}[/tex]
=32.24
Hence, set 1 and set 2 have same standard deviation.
c. Set 1: 10, 16, 18, 20, 22, 28
Set 2: 48, 56, 58, 60, 62, 70
Set 2 generally has larger values, suggesting that it could have a larger standard deviation because the mean is larger for set 2.
For Set 1:
Mean = (10 + 16 + 18 + 20 + 22 + 28) / 6
= 19
Standard Deviation = [tex]\sqrt{\frac{(10-19)^2 + (16-19)^2 + (18-19)^2 + (20-19)^2 + (22-19)^2 + (28-19)^2)}{6}}[/tex]
= 5.50
For Set 2:
Mean = (48 + 56 + 58 + 60 + 62 + 70) / 6
= 58.33
Standard Deviation = [tex]\sqrt{\frac{(48-58.33)^2 + (56-58.33)^2 + (58-58.33)^2 + (60-58.33)^2 + (62-58.33)^2 + (70-58.33)^2)}{6}}[/tex]
=6.641
Hence, the second set have the larger standard deviation.

Each package of dried fruit contains 3/16 of a pound Mr. Lopez has 4 pounds of dried fruit How many packages can he fill
Final answer:
Mr. Lopez can fill 21 full packages of dried fruit, each containing 3/16 of a pound, with his 4 pounds of dried fruit.
Explanation:
The question asks how many packages of dried fruit Mr. Lopez can fill if each package contains 3/16 of a pound and he has 4 pounds of dried fruit. To answer this, we need to perform a division to find out how many 3/16 are in 4 pounds.
To solve this, we divide 4 pounds by 3/16 pounds per package:
4 ÷ (3/16) = (4/1) ÷ (3/16) = (4 × 16) / 3 = 64/3 = 21 with remainder 1.
Therefore, Mr. Lopez can fill 21 full packages of dried fruit and will have a little left over which is not enough to fill an additional full package.

what is the exact of the expressions square root of 180 - square root of 125 + square root of 5
The exact value of the expression √180 - √125 + √5 simplifies to 2√5, by combining like terms after simplifying each square root separately.
The exact value of the expression [tex]\sqrt{180}[/tex] - [tex]\sqrt{125}[/tex] + [tex]\sqrt{5}[/tex] can be calculated by simplifying each square root separately. Firstly, the [tex]\sqrt{180}[/tex] can be simplified to 6√5, because 180 = 36 × 5, and 36 is a perfect square whose square root is 6. Similarly, the [tex]\sqrt{125}[/tex] simplifies to 5√5, since 125 = 25 × 5 and the [tex]\sqrt{25}[/tex] is 5. The [tex]\sqrt{5}[/tex] remains as it is because it cannot be simplified further.
The expression then becomes 6√5 - 5√5 + √5. Now, we combine like terms. Since all terms involve the [tex]\sqrt{5}[/tex], we can combine them as follows: (6 - 5 + 1)√5, which simplifies to 2√5. Therefore, the exact value of the expression is 2√5.
