Step-by-step explanation:
(23)2-5=6
23 3 =6
so it goanna be 2raise to power 3x equal6
We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
Answer:
≈ 4.27 meters high
Step-by-step explanation:
Roberto's house is 14 feet high, we also know that 1 foot equals about 0.305 meters, so since we have 14 feet, we multiply 0.305 by 14 :
0.305 * 14
==> 4.27 meters
They are all pretty easy all you do is multiply the cost by the amount of things you buy. For example number 4 your variables are cost (c) and songs (s). Your equation is c•s so $0.99 • s. 50 songs would be .99 • 50 which is $49.50
