Answer:

15.95 feets

Step-by-step explanation:

Given that:

Angle of elevation = 62°

Using trigonometric relation :

Tanθ = opposite / Adjacent

From the drawing attached :

Opposite = 30 feets

Distance between girl and lighthouse = d

Tan 62 = 30 / d

1.8807264 * d = 30

d = 30 / 1.8807264

d = 15.951283

d = 15.95 feets

Find the values of x in this equation: x – 15 x = 2 . A. -7, 3 B. -5, 2 C. -7, 5 D. -2, 5 E. -3, 5
givi [52]

Answer:

Step-by-step explanation:

The given expression is x- \frac{15}{x} = 2

and we have to solve this for the value of x,

( x- \frac{15}{x}) = (2)

\frac{x^{2}-15 }{x} =2

x² - 15 = 2x

x² - 2x - 15 = 0

x² - 5x + 3x - 15 = 0

x ( x-5 ) + 3(x - 5) = 0

( x+3 )( x-5 ) = 0

( x+3) = 0

x = -3

or ( x- 5 ) = 0

x = 5

Therefore, x = -3 and 5 will be the solution.

Option E is the answer.

Otto has some whipping cream that is 30%, butterfat, and some milk that is 2%, butterfat. He wants to make a 500 ML mixture of t
timofeeve [1]

The point J connote that the mixture has more than the expected volume and has the optimal butterfat percentage.

<h3>What is the point implying?</h3>

Note that in the question, it was supplied that  Otto intended to make a mixture of 12% butter fat.

Since:

Milk = 2% butter fat

Whipping cream = 30% butter fat.

This implies that  the milk contains the smallest of butter fat and it also implies that Otto would require  a lot more milk than cream, to be able to attain the 12% mixture.

This is known to be when point J is said to meet, and by using that data from point J, Otto require more of milk than the cream to get what he wants.

Therefore, The point J connote that the mixture has more than the expected volume and has the optimal butterfat percentage.

A glass triangular prism for a telescope is 5.5 inches long. Each side of the prism's triangular bases is 4 inches long and 3 in
fiasKO [112]

Answer:

78 square inches

Step-by-step explanation:

It is given that the length of the glass triangular prism for a telescope=5.5 inches, sides of the triangular prism = 4 inches and height =3 inches.

Thus, Surface area of the triangular prism =bh+(s_{1}+ s_{2}+s_{3})H where H is the length of the triangular prism.

SA=(4)(3)+(4+4+4)(5.5)

=12+12(5.5)

=78 square inches.

Write and solve a story problem about gathering three kinds of vegetables. Use 10 partners.
Nata [24]

Answer:

Cameron and Rebecca are organizing a lunch for their friends. Within the dishes to be served, they will prepare a tomato, carrot and broccoli salad. The number of tomatoes and carrots are 10-partners and the total amount of vegetables is 12. If we increase the number of broccoli by three and decrease the number of tomatoes by two, the amount of tomatoes and broccoli will also be 10-partners. What is the number of tomatoes, carrots and broccoli bought by Cameron and Rebecca?

<u>Cameron and Rebecca purchased 7 tomatoes, 3 carrots and 2 broccoli.</u>

Step-by-step explanation:

Number of tomatoes = x

Number of carrots = 10 - x

Number of broccoli = y

System of Equations:

x + 10 - x + y = 12

y = 12 - 10

y = 2

x - 2 + y + 3 = 10 (If we increase the number of broccoli by three and decrease the number of tomatoes by two, the amount of tomatoes and broccoli will also be 10-partners)

x + 1 + y = 10

x + y = 9

y = 9 - x

Substitution of y:

x + 10 - x + y = 12

x + 10 - x + 9 - x = 12

-x + 19 = 12

-x = 12 - 19

x = 7 ⇒ 10 - x = 3

<u>Cameron and Rebecca purchased 7 tomatoes, 3 carrots and 2 broccoli.</u>
