Answer:
400 degrees
Step-by-step explanation:
Step 1 : To convert radians to degrees, multiply the given radian by 180/pi
7pi/3 x 180/pi
Step 2 : Cancel pi
7/3 x 180
= 420 degrees
Step 3 : Round it to nearest 100
Since 20 is closer to 400 than 500 therefore it will be rounded off to
400 degrees
!!
(0, 10) is the difference
Answer:
∠TUS I'm pretty sure because t and u make a right angle
Calculate the interest in a year
Multiply the annual percentage of interest by the investment to find the interest.
interest in a year = 2% × 1,000
interest in a year = 0.02 × 1,000
interest in a year = 20
The annual interest is $20
Calculate the interest after 10 years
Multiply the annual interest by 10
interest 10 years = 20 × 10
interest 10 years = 200
The sum of interest after 10 years is $200
Find total investment
investment = first investment + interest in 10 years
investment = 1,000 + 200
investment = 1,200
The investment will be worth $1,200 in 10 years
