In Sichuan, China, Bernards stands at the top of the Jinping-1 dam and measures the angle of depression down to where Benjamin is standing at 1999 feet from the base of the dam. If the angle of depression is 26.6 degrees, how tall is the dam? Round to the nearest foot.
Answer:
This illustrates a right triangle.
Given:
a(height) = 2457 ft.
∠A = 22°23' ; which is the elevation and reflects the a(height)
Find:
b(base)
Solution:
Using the law of cosine, specifically tan∠ = opposite side÷adjacent side
By analysis, tan∠A = a÷b
Since we are finding b, the formula will be derived into:
b = a÷tan∠A
Find b(base):
b = 2457 ft. ÷ tan22°23' ; substituting the numbers
b ≈ 5,966.05 ft. ; Final Answer
Step-by-step explanation:
(a+b)²= ?
please tell the correct answer
Step-by-step explanation:
[tex](a + {b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]

URGENTT!! Susan will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.60 per mile driven. The second plan has an initial fee of $75 and costs an additional $0.10 per mile driven. How many miles would Susan need to drive for the two plans to cost the same?
Answer:
150 miles
Step-by-step explanation:
Let
x = number of miles
Plan A: 0.60x
Plan B: 75 + 0.10x
How many miles would Susan need to drive for the two plans to cost the same?
0.60x =75 + 0.10x
0.60x - 0.10x = 75
0.50x =75
x = 75/0.50
x = 150 miles
Susan needs to drive for 150 miles for the two plans to cost the same

A comet passes Earth every 70 years. Another comet passes Earth
every 75 years. If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Answer:
1,050 years
Step-by-step explanation:
A comet passes Earth every 70 years.
Another comet passes Earth
every 75 years
If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?
Find the lowest common multiple of 70 years and 75 years
70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,
75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350
Lowest common multiple of 70 years and 75 years is 1,050 years
Therefore,
If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

Which expression is equivalent to 3 p+15? (4 points)
оа
1
3 (p+45)
Ob
1
3 (p+5)
3(p + 45)
Ос
Od
3(p + 5)
Answer:
um, I am confused on the answer options, but 3(p+5) is equivalent
Step-by-step explanation:
3p+15 is the same a 3(p+5) because in 3(p+5) we have to use the distribution property
So, it is 3p +15 here's a picture to explain it better
(3(p+45) would be too big of a number as you also use the distribution property and it would be 3p+135)
what is the answer 333
Answer:
Option A wilk be the correct answer.
Answer:
a. acute, equilateral
Step-by-step explanation:
From the picture the lines on the triangle mean that the sides are equivalent to one another so from that you can eliminate option c. There are not right angles within the triangle so you can eliminate option b. The angles are less than 90 degrees as they arent even cloe to being a right angle so they arent obtuse so you can eliminate option d. Now you are only left with option a.
If you were given the choice of between more initial zombies, but a slower growth rate or fewer initial zombies, but a greater growth rate, which would you pick and why?
I would chose more initial zombies, but a slower growth rate because when they grow stronger, you get stronger so you have a better chance of survival if their development rate is gradual, giving you time to collect weapons and construct a shelter.
What is growth rate?Growth rate refers to the percentage increase or decrease in a particular variable over a specific period of time. It is commonly used in finance, economics, and business to describe the rate of change of various economic indicators such as gross domestic product (GDP), population, revenue, profit, and so on.
here, we have,
To calculate the growth rate, you need to divide the difference between the final value and the initial value of the variable by the initial value, and then multiply the result by 100 to express it as a percentage. The formula for growth rate is as follows:
Growth rate = ((Final value - Initial value) / Initial value) x 100

Ben finds 4 + 11 using a number line. He counts 11 on from 4. Which is a faster way to solve this problem
Step-by-step explanation:
The way to solve the problem would be just add the two number as 11+4 =15.
This would avoid the tedious process first drawing the number line and then counting each number to reach the same answer, which could be easily reached by just adding the two numbers.
12. Solomon scored 88% on his math test. If the test had 25 questions total, how many
questions did Solomon miss?
Answer:
He missed 3 questions (which is a score of 22/25 that equals 88%)
Step-by-step explanation:
This is just what I've taught to judge this by "eye level" how to solve questions like these. In this case, since it's a 25 question test, if you divide 25/100 that means each question was 4 points.
So if 20/25 is 80% and 25/25 is 100%, so the answer is between that range.
Hope it helps.

Jill paid a sales tax of $1.40 when she bought a vest. What was price of vest not including tax? Sales tax = 3.5%
Answer:
$40
Step-by-step explanation:
Tax is a sum levied by the government or an agency of the government on goods and services. taxes increases the price of products

There’s 18 boys and 11 girls in a class, they make a team with 7 students
a) in how many ways can they pick a team
b) how many teams can they get knowing there is 4 boys in each one?
"The number of boys is 45 the number of girls,"
or to say,
"The ratio of the number of boys to the number of girls is 45:1."
This second interpretation reflects the fact that 45 is the unit rate (which is a number) for the ratio 4:5.
what is the value of a? what is the value of b?
Answer:
b=18, a=9√3

You and a friend go to surf taco for lunch. you order 3 soft tacos and 2 burritos and your total bill is 25. Your friend bill is 30 for 5 soft tacos and 2 burritos. How much do soft tacos cost? 3x+2y=25 4x+2y=30 X-soft tacos y-burritos
Answer:
Step-by-step explanation:
Let the cost of one soft taco = s
Let the cost of one burrito = b
So we have this system
3s + 3b = 11.25
4s + 2b = 10.00 (1)
Divide the first equation through by 3 and we have that
s + b = 3.75 subtract b from both sides
s = 3.75 - b (2)
Sub (2) into (1) and we have
4 (3.75 - b) + 2b = 10.00 simplify
15 - 4b + 2b = 10.00
-2b + 15 =10.00 subtract 15 from both sides
-2b = - 5.00 divide both sides by -2
b = 2.50
And using (2)
s = 3.75 - 2.50 = 1.50
So... a soft taco 1.50 and a burrito is 2.50
