Answer 1

Answer:

Answer:

Step-by-step explanation:

7 is the common denominator.

5 + 6 + 2

========

13/7

1 6/7

1.857

Answer 2

Answer:

Hi! I believe your answer is 1 17/35 or ---1 $(17)/(35)$ --- because these fractions all have the same denominator, so simply add them all up! You get 13/7, which is an improper fraction. Simplify it by dividing 13 by 7. The answer is 1 17/35, which you cannot simplify anymore. I hope this answer helps you! Good luck and have a great day. :)

Find the value of t

Answers

Answer: t = 51

Step-by-step explanation:

Well hello buddy. How are you doing today? Might be a little bit bad because you have to deal with this weird triangle. BUT DONT WORRY DOG. I GOT YOU.

notice that that 112 number is on a straight line.... and straight lines are 180 degrees

With this in mind, lets subtract: 180 - 112 and we get= 68

ok so now we have these triangle angles: 68 and 61. also keep in mind that all angles of a triangle add up to 180

so 68 + 61 = 129

now do this: 180 - 129

the answer is 51

Answer:

51⁰

Step-by-step explanation:

there are 180⁰ on a straight line so if substrate 112⁰ from 180⁰ the answer will be 68⁰ so now we can get T simply like this below

61⁰+68⁰+T=180⁰

129⁰+T=180⁰

T=180⁰-129⁰

T=51⁰

Write the expression multiply 0.035 times of a power of 10 so that the product is greater than one by less than 100

Answers

Answer:

$0.035* 10^(3)$

$0.035* 10^(2)$

Step-by-step explanation:

Given the number: 0.035 which has three decimal place

Case 1: if we multiply by 10

=> we have: 0.035*10 = 0.35

Hence, the product 0.35 which is smaller than 1 (we do not accept)

Case 2: if we multiply by 1000

=> we have: 0.035*1000 = 35

Hence, the product 35 which is greater than 1 and less than 100

Case 3: if we multiply by 100

=> we have: 0.035*100= 3.5

Hence, the product 3.5 which is greater than 1 and less than 100

Case 4: if we multiply by 10000

=> we have: 0.035*10000= 350

Hence, the product 350 which is greater than 100 (we do not accept)

Therefore, we have two expression:

$0.035* 10^(3)$

$0.035* 10^(2)$

A boat is heading towards a lighthouse, whose beacon-light is 131 feet above thewater. From point A, the boat's crew measures the angle of elevation to the beacon,
5°, before they draw closer. They measure the angle of elevation a second time from
point B at some later time to be 21°. Find the distance from point A to point B.
Round your answer to the nearest tenth of a foot if necessary.

Answers

Answer:

Step-by-step explanation:

Assuming a flat earth

initial measurement

tan5 = 131 / d₁

d₁ = 131/tan5 = 1,497.3368... ft

d₂ = 131/tan21 = 341.2666674...ft

distance from A to B

1497.3368 - 341.26666 = 1,156.1 ft

Rather daring to specify to the answer to the nearest tenth of a foot when no given measurement accuracy is even close to that same precision.

Final answer:

This is a trigonometry problem that can be solved by using the tangent function to find the distances from the boat to the lighthouse at two different angles of elevation, and then subtracting to find the distance travelled by the boat.

Explanation:

This question involves the concept of trigonometry, specifically inverse trigonometric functions. We can solve it by creating two right triangles and using the trigonometric function known as tangent. Due to the nature of the problem, we will consider the lighthouse as the opposite side while the distance from the boat to the lighthouse will serve as the adjacent side.

When the boat is at point A, we can write the following equation using the tangent of 5° - tan(5°) = 131/DistanceA. Solve this equation to find DistanceA.

Next, do the same when the boat is at point B. The equation for this scenario is - tan(21°) = 131/DistanceB. Resolve this equation to find DistanceB.

The distance from point A to B (which is what the question asks for) is just the difference between DistanceA and DistanceB. Make sure to take the absolute value to avoid a negative distance, and round the result to the nearest tenth of a foot if necessary.
