Jane: Think: the hypotenuse of her ramp is 14 inches and the angle opposite the rise is 30 degrees. Thus, cos 30 deg = (adj side) / (hyp) = (adj side) / (14 in).

Solving for (adj side), we get (adj side) = (14 in)(sqrt(3)/2) = 7 sqrt(3) inches.

Answer:

-5/12

Step-by-step explanation:

Let's solve your equation step-by-step.

1 /3 = n + 3 /4

Step 1: Flip the equation.

n + 3 /4 = 1/ 3

Step 2: Subtract 3/4 from both sides.

n+ 3 /4 − 3/4 = 1/ 3 − 3 /4

n= −5 /12

An element with mass 130 grams decays by 22% per minute. How much of the element is remaining after 7 minutes, to the nearest 10

shepuryov [24]

22.8 grams of element will be remaining after 7 minutes

Further explanation:

Given

$Mass\ of\ element=130g\\Percentage\ of\ reduction=22\%$

The element reduces (1-22%) in one minute.

The process will be repeated 7 times for 7 minutes

If we have to calculate the amount of element after 7 minutes

then the total reduction will be: (1-22%)^7

$Remaining\ amount=130*(1-22\%)^7\\=130*(1-0.22)^7\\=130*(0.78)^7\\=130*0.18\\=22.84g\\Rounding\ off\ to\ nearest\ tenth\\=22.8g$

22.8 grams of element will be remaining after 7 minutes

A store has a 28% off sale on hammers. Before the discount, the price of a hammer is $49. What is the sale price?

zheka24 [161]

28% of 49 is 13.72. So subtract that from 49 and you get 35.28. 35.28 is the price after the sale
