Answer:
a = 4.6
b = 4.2
Step-by-step explanation:
to find a, use cos:
⇒ cos = 
⇒ cos 30 = 
cos of 30 is 0.154
⇒ 0.154 =
multiply 13 on both sides:
⇒ 0.154 x 13 = x 13
⇒ 4.62 = a
round to the nearest tenth:
⇒ 4.62 = 4.6
⇒ a = 4.6
to find b, use tan:
⇒ tan = 
⇒ tan 60 = 
tan of 60 is 0.320
⇒ 0.320 =
multiply 13 on both sides:
⇒ 0.320 x 13 = x 13
⇒ 4.16 = b
round to the nearest tenth:
⇒ 4.16 = 4.2
⇒ b = 4.2
1. 77 mph
We already know they travel 38.5 miles in 30 minutes. So we multiply 38.5 x 2 because 30 minutes is 1/2 of an hour. 38.5 x 2 = 77
5. 8.5 minutes (8 minutes and 30 seconds) per mile
We have to divide 25.5 by 3 to know how many minutes it takes Jerry to run one mile.
8. 34.06
This one is kinda easier. We already know 34 is the whole number. 6 divided by 100 is 0.06, so we simply add 34 + 0.06
Answer:
i think the answer is 195
Answer: See explanation
Step-by-step explanation:
The constant multiple of liters in a jug to the weight in kilograms will be:
7 kg = 9.7 liters
1 liter = 7/9.7 kg
The number of kilograms a 48.5 liter jug of a sports drink would weigh will be:
= 7/9.7 × 48.5
= 35kg
