If you write down your information first it will be easier to visualise a method:

15 rolls of ribbon, each is $5\frac{3}{8}$ yards long. 10 wedding baskets. She takes $\frac{3}{4}$ yards away from every basket.

So, in mathematical terms:

$(15*5\frac{3}{8})-10(\frac{3}{4})\\\\(15*\frac{43}{8})-5(\frac{3}{2})\\\\(\frac{645}{8})-\frac{15}{2}\\\\\frac{645}{8}-\frac{60}{8}\\\\\frac{585}{8}\\\\585/8=73.125$

Your answer is $\frac{585}{8}$ or 73.125 yards.

An airplane pilot over the Pacific sights an atoll at an angle of depression of 10°. At this time, the horizontal distance from

Alex17521 [72]

The question was posted incomplete.

This is the part missing:

What is the height of the plane to the nearest meter?

Answer: 559 m.

Explanation:

1) The horizontal distance between the plane and tha atoll makes a right triangle with the height, with the depression angle between the two legs.

2) Therefore, you can use the tangent trigonometric ratio:

tan(10°) = opposite-leg / adyacent-leg = height / horizontal distance

⇒ height = horizontal distance × tan (10°)

⇒ height = 3,172 m × tan(10°) = 559.31 m, which rounded to the nearest m is 559

Help me!! A water tank is 1/8 full. The tank is 3/4 full when 42 gallons of water is added to the tank. How much can the water t

chubhunter [2.5K]

Answer(s):

1.) 56 gallons

2.) 7 gallons

3.) 28 gallons

Step-by-step explanation:

Q1: How much water can the tank hold?

Based on the question, we know that 3/4 of the tank equals 42 gallons. Divide 42 by the numerator, 3.

42/3 = 14

Now, multiply 14 by the denominator, 4.

14 x 4 = 56.

So, the tank can hold 56 gallons. [If you'd like to double check this answer, take the fraction 42/56 and simplify it to get 3/4.

Q2: How much water was originally in the tank?

We know that the tank's maximum capacity is 56 gallons. So, if it was 1/8 originally full, multiply 56 by 1/8. [Remember that 56 as a fraction can be written as 56/1]

1/8(56/1) = 7

This means that the tank was originally 7 gallons full. [If you'd like to double check this answer, take the fraction 1/8 and multiply the numerator and denominator by 7. This gets you 7/56, or 7 gallons out of the total capacity, 56 gallons.]

Q3: How much water is in the tank when it is 1/2 full?

Earlier, we found out that the maximum capacity of the tank is 56 gallons. To find out how many gallons it holds when its half full, divide 56 by 2.

56/2 = 28

So, when the tank is 1/2 full, it contains 28 gallons. [If you want to double check this answer, take the fraction 28/56 and simplify it. When you do, you get 1/2.]

the captain of a boat knows that the lighthouse on the coast is 200 feet tall. he measures the angle of elevation to the top of

krek1111 [17]

Answer:

The boat is 5727.25ft far from the coast

Step-by-step explanation:

Refer the figure given.

We need to find how far is the boat from the coast = AB

Angle of elevation = 2°

The lighthouse on the coast is 200 feet tall, AC = 200 ft

We have

$tan2=\frac{AC}{AB}=\frac{200}{AB}\\\\AB=\frac{200}{tan2}=5727.25ft$

The boat is 5727.25ft far from the coast
