Using the concept of proportionality we shall solve for the unknown altitude as follows:
let the measure of the altitude be x:
24/16=x/6
solving for x we get:
x=24/16*6
x=9 feet
Answer: 9 feet

Plzz help find value of following : 2sin75°.cos15°

polet [3.4K]

Answer:

$\frac{2+\sqrt{3} }{2}$

Step-by-step explanation:

Using the product to sum formula

sinxcosy = $\frac{1}{2}$ [ sin(x + y) + sin(x - y) ] , then

2sinxcosy = sin(x + y) + sin(x - y)

Given

2sin75°cos15° ← with x = 75 and y = 15 , then

= sin(75 + 15) + sin(75 - 15)

= sin90° + sin60°

= 1 + $\frac{\sqrt{3} }{2}$

= $\frac{2+\sqrt{3} }{2}$

Alice earned $622.50 in interest on her savings in the bank. Before interest, the account had $12,450. What is the approximate p

Lubov Fominskaja [6]

Answer:

Explanation:

% she earned in interest can be calculated by calculating the % of increase in the balance

We have:

Original balance = $12,450

Amount of interest = $622.5

This means that:

new balance = 12,450 + 622.5 = $13,072.5

Now, we can get the percentage of increase:

% of increase = $\frac{Value_n_e_w - Value_o_l_d}{Value_o_l_d} *100$

Substitute with the values we have to get the percentage of interest earned as follows:

% of interest earned = $\frac{13072.5 - 12450}{12450} * 100$ = 5%

Hope this helps :)
