A bird flying at an altitude of 50 feet spies a worm in the ground up ahead. How far must the bird travel to the worm if the angle of depression from the bird to the worm is 56°?
Answer:
33.7 ft
Step-by-step explanation:
We solve the above question using Trigonometric function of Tangent
tan θ = opposite/adjacent
θ = 56°
Opposite = 50 ft
Adjacent = x
Cross Multiply
tan 56 = 50 ft/x
Cross Mulitiply
tan 56 × x = 50ft
x = 50ft/tan 56
x = 33.725425842 ft
Approximately = 33.7 ft
The bird must travel 33.7 ft to meet the worm

In what ratio must 40m3 be decreased to become 24m3?
Answer:
40m3 must be decreased by 40% to become 24m3.
Step-by-step explanation:
To determine in what ratio must 40m3 be decreased to become 24m3, the following calculation must be performed:
40 = 100
24 = X
24 x 100/40 = X
2400/40 = X
60 = X
100 - 60 = 40
Therefore, 40m3 must be decreased by 40% to become 24m3.

After that incident, the Civil defense team decided to buy new trucks with ladders higher than 100 feet. They found 2 different trucks with the same height of ladders. The first truck costs $145,000 and will cost $0.31 per mile traveled based on the current gas prices. The second truck will cost $160,000 but gets better gas mileage, costing $0.27 per mile. They need to decide which truck is the best deal.
Answer:
the first truck
Step-by-step explanation:
the cost difference between the first truck and the second truck = $160,000-$145,000 = $15,000
the difference of gas cost between the first truck and the second truck = $0.31 - $0.26= $0.05 per mile.
so,
I think, this is a very significant number of truck cost compared with gas cost
for the best deal, the first truck is the best choice.

Answer: Infinitely many solutions.
Step-by-step explanation:
Which set of coordinates follows these two rules x coordinate start with 4 and add 4 to each term y coordinate start with 4 and multiply each term by 2
A (4, 4), (8, 8), (12, 16)
B (4, 4), (8, 8), (16, 16)
C (4, 4), (6, 16),(8, 64)
D (4, 4), (16,2), (64,0)
Answer:
A; (4,4), (8,8) and (12,16)
Step-by-step explanation:
The value x starts with 4 and add 4 to each term
The value y start with 4 and each term next is multiplied by 2
So for x, we have;
4 , (4 + 4) and (4 + 4 + 4)
= 4,8 and 12
For y;
we have ;
4, (4 * 2) , (4 * 2 * 2)
= 4, 8, 16
so pairing up, we have;
(4,4), (8,8) and (12,16)

An artist receives royalties for all digital downloads of his music. For the first 10,000 downloads, the artist receives $10,000. He receives $12,500 for the next 10,000 downloads, $15,000 for the next 10,000 downloads and so on. How much money will he receive if his music is downloaded 500,000 times?
Answer:
Step-by-step explanation:
This is a linear relationship. We know this because as the number of songs increases by 10,000 the amount of money increases $2500. We can use that relationship in a proportion, which is a method used to solve problems involving directly proportional numbers.
If we arrange our information such that the dollars earned are on the top of the fraction and the number of songs that need to be downloaded to earn that amount of money is on the bottom of the fraction, here is what we have:
[tex]\frac{2500}{10,000}[/tex]. This means that the artist receives $2500 for every 10,000 downloads. Keeping in that pattern, we can find out how much money he will earn when 500,000 downloads are completed, assuming that the amount he earns per 10,000 songs doesn't change.
[tex]\frac{2500}{10000}=\frac{x}{500000}[/tex] and cross multiply to get
10,000x = 1250000000 and divide to get
x = 125,000
That is the amount that he will earn from 500,000 downloads.

Answer:
Hi answer: 41What I do for these is do the shapes separately and use the appropriate formulas! Then add them Up! So the easiest is the rectangle that would be 5 × 4 = 20 then the triangles would be 5 x 1 = 5 then ÷ by 2 = 2.5 but since there are two of those triangles we just multiply by 2 again so 2.5 × 2 = 5 for the last two triangles at the top it would be 4 × 4 = 16 then ÷ by 2 = 8 but since theres 2 triangles multiply by 2 so 8 × 2 = 16 now we add all of these numbers up so 20 + 5 + 16 = 41 Hope that helps!
