N/5 - 7 = -11
n/5 - 7 (+7) = -11 (+7)
n/5 = -4
n/5 (5) = -4(5)
n = -20
hope this helps
Answer:
1. 4.7
2. 5,082
Step-by-step explanation:
1. To find the volume of a cone you use this formula . The diameter is 3 so to find the radius, divide it by 2 (3/2=1.5) and we know the height. Input the numbers into the formula and solve which is equal to . To find HALF, divide that answer by 2. , round to the nearest tenth, making the answer 4.7!
2. To find the volume of a rectangular prism you use . Input the numbers, to find the amount of water for the bigger tank (5,760). Now follow the same process to find the amount of water for the smaller tank which is 678. Now subtract the smaller tank amount (678) from the larger tank since you're taking the water from the bigger tank to fill the smaller one which equals 5,082.
B because in commutative property of addition the numbers switch but they do not change the sign nor the numbers. hope this helped
Volume of a cylinder is calculated as pi x radius x radius x height
pi is 3.14
so volume = 3.14 x 6 feet x 6 feet x 12 feet = 1356.48 ft3
so the correct answer is C)1,357 ft3
Answer:
tan x = opp / adj = -3/4
Step-by-step explanation:
If sin x = -3/5, then we have the following info as a starting point:
opposite side = -3 (implying that the angle is in either QIII or QIV), and
hypotenuse = 5.
Using the Pythagorean Theorem, we find that x² + (-3)² = 5², where x is the length of the adjacent side. Solving for x², we get x² = 25-9 = 16, so that the adj. side, x, is either +4 or -4.
If cos x > 0, then x must be in either QI or QIV.
If both conditions are satisfied (sin x = -3/5 and cos x > 0), then the angle x must be in QIV.
Then tan x = opp / adj = -3/4.
