The answer to number 1 is C. Not sure how to get that, I just got it off line converting it with a website.
The answer to number 2 in B, also got that offline by converting it.
3.) Area of a circle:
Radius-16
16×16×3.14=803.84 rounded to the nearest number is 804.
Since this says ESTIMATED we look for the closest answer to 804.
The answer is C. 805 square meters. hope it helps!!!!!!!!!!!!!!!
500 I guess it’s not right
Your heart rate is the number of times each minute that your heart beats, which is normally between 60 and 100 times per minute for adults. Your pulse is a way you can feel each time your heart beats. Measuring your heart rate helps you monitor your own health and know if you’re exercising at the right level to get the most benefits to your health.
Your pulse is your heart rate, or the number of times your heart beats in one minute. Pulse rates vary from person to person. Your pulse is lower when you are at rest and increases when you exercise (more oxygen-rich blood is needed by the body when you exercise). Knowing how to take your pulse can help you evaluate your exercise program.
We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅
in this problem
see the attached figure to better understand the problemangle ∅=80°
opposite side angle ∅=12 ft (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft
the answer is2.12 ft
