Rin spends $20 every week on drum lessons.
mihalych1998 [28]

Answer:

A, B, D and F.

Step-by-step explanation:

Rin spends $20 every week on drum lessons.

If:

d = total amount of dollars Rin spends

w = number of weeks

Then: d=20w

w is the independent variable while d is the dependent variable. A change in w will lead to a change in d. Therefore:

(A)The independent variable causes a change in the  dependent variable.

(B)The equation is d = 20w.

From the equation: d=20w

When w=1, d=$20

When w=2, d=$40

When w=3, d=$60

When w=4, d=$80

This tallys with the values in Option  F.

Therefore:

(D)As the number of weeks increases, the total dollars  Rin spends increases.

The correct options are: A, B, D and F.

A ladder is leaning against a building and makes 28 degree angle with the ground.
Dominik [7]

To solve this problem you must apply the proccedure shown below:

1- You have that the laddder makes an angle of 28 degrees with the ground and the top of the ladder reaches 35ft.

2- Therefore, you have:

Sin\alpha =\frac{opposite}{hypotenuse}

Where:

opposite=35\\ hypotenuse=length\\ \alpha =28degrees

3-You must substitute values and solve for the lenght, as following:

Sin(28)=\frac{35}{lenght}  \\lenght=\frac{35}{Sin(28)}  \\ lenght=75ft

Therefore, the answer is: 75ft
