Answer:
4 hours × 0.8°C = 3.2°C
temperature after 4 hours
= -2.4°C - 3.2°C
= -5.6°C
A = pi r^2
A = 3.14 x 7^2
A = 3.14 x 49
A = 153.86
Answer:
The tree is 14 ft. tall.
Step-by-step explanation:
If Ryan is 6 ft. tall and his shadow is 12 ft. tall than his shadow is twice his size. So if the trees shadow is 28 ft. tall then you would divide. Here is the equation:
28 ÷ 2 = 14
To check our work you would do 14 * 2 = 28.
Hope this helps!!
To work out this question, you need to think of what ratio there is of white cars to yellow cars.
You know that there are 9 times as many white cars as yellow cars.
This means for every white car you have, you have 9 yellow. 1:9.
So for every 10 cars we have (9+1) we have 1 white car and 9 yellow cars.
Next, we take the total number of cars (40) and divide it by the total number of white+yellow cars we have (10)
40 / 10 = 4.
Now, we times 4 by the numbers in the ratio.
1 x 4 = 4.
9 x 4 = 36.
We can double check this by doing 36 / 4 = 9.
We know that Rafael counted 4 white cars.
The highest degree of any term is 8, so that is the degree of the polynomial.
