Answer:
yes, but the answer will be a decimal. the answer is 16.5.
Step-by-step explanation:
1 quart = 32 ounces
2 x 32 = 64
$6.40 divided by 64 ounces
.10 per ounce
Answer:
6.5 feet
Step-by-step explanation:
Based on the Cosines Law, we have:
![cos(B) = \frac{c^{2} + a^{2} - b^{2} }{2 * a * c}](https://tex.z-dn.net/?f=cos%28B%29%20%3D%20%5Cfrac%7Bc%5E%7B2%7D%20%2B%20a%5E%7B2%7D%20-%20b%5E%7B2%7D%20%7D%7B2%20%2A%20a%20%2A%20c%7D)
If we isolate b (which is our x in this problem), we have
![b = \sqrt{a^{2} + c^{2} - 2 * a * c * cos(B)}](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%7Ba%5E%7B2%7D%20%20%2B%20c%5E%7B2%7D%20%20-%202%20%2A%20a%20%2A%20c%20%2A%20cos%28B%29%7D)
We have
a: 2
c: 5
B: 131 (since it's the complement of the 49 degrees angle: 180 - 49).
So, we plug these numbers in the formula....
![b = \sqrt{2^{2} + 5^{2} - 2 * 2 * 5 * cos(131)} = 6.49](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%7B2%5E%7B2%7D%20%20%2B%205%5E%7B2%7D%20%20-%202%20%2A%202%20%2A%205%20%2A%20cos%28131%29%7D%20%20%3D%206.49)
We round it up to the tenth of the unit... to get 6.5
Area = length x width
Area = (5x + 1)*(3x - 2)
Area = 5x*3x + 5x*-2 + 1*3x + 1*-2
Area = 15x^2 - 10x + 3x - 2
Area = 15x^2 - 7x - 2 :)
Answer:
30
Step-by-step explanation:
The triangles are similar because of Hypotenuses- Leg. Therefore,
∠RSU ≅ ∠TSU
c + 30 = 2c
30 = c (Subtract c from both sides.
