Answer:
5.6 = AB
Step-by-step explanation:
Since this is a right triangle, we can use trig functions to find the length of AB
Cos theta = opp side/ hypotenuse
cos 62 = AB / BC
cos 62 = AB /12
Multiply each side by 12
12 cos 62 = AB
5.633658753 = AB
Rounding to 1 decimal place
5.6 = AB
We can also find AC
sin theta = opp side/ hypotenuse
sin 62 = AC / BC
sin 62 = AC /12
Multiply each side by 12
12 sin 62 = AC
10.59537111 = AC
Rounding to 1 decimal place
10.6 = AC
5 m/s · 12 s = 5 m · 12 = 60 m
Answer: in 12 seconds that car has gone 60 metres.
Answer:
2 1/4 cups
Step-by-step explanation:
Since we want half as many cookies as the recipe can make, we just half the amount of ingredients used.
Originally, we have 4 1/2 cups of flour for 48 cookies. However, for 24 cookies, which is half of 48, we want to have half of 4 1/2: (4 1/2)/2 = 2 1/4 cups.
Thus, the answer is 2 1/4 cups of flour.
Hope this helps!

Answer:
b+2(b+2b) = 7b so this is incorrect.
3b + b = 4b (correct)
2 * 2b = 4b (correct)
The answer is 3b + b and 2 (2b)
