Answer: 76
Step-by-step explanation: 29 + 47
Answer:
B.) About 2 hours
Step-by-step explanation:
Well the Full volume of the tank is 1440 cubic feet. If you multiply 15 by sixty, thats 900. 900 is cubic feet per hour, so there are 1.6 times 900 in 1440. Therefore 1.6 hours to drain the whole thing and B is the closest answer.
Answer:
7/8 ≈ .9
y = -3x/4 + 4.75
x = 9 ⅓
Rotation
Step-by-step explanation:
1.) 7/8 = 0.875 The hundredths place is 7, which means we round up to 0.9
2.) Isolate the y on the left. Then divide both sides by 4
3.) Subtract 7 from both sides, then divide both sides by 3
Rotation turns around a point Reflection flips across a line.
Answer:
Step-by-step explanation:
The idea here is to find the value for x and y, then add them together. See the pic I attached below. We will solve for side x first.
Side s is across from the reference angle of 48 degrees; side measuring 50 m is adjacent to the reference angle 48 degrees. Therefore, we will use the tangent ratio to solve for x:
and
50tan(48) = x so
x = 55.53m
Now we will do the same and solve for y. This time the reference angle is 28 degrees. Side y is opposite the reference angle and the side measuring 50 is adjacent to the reference angle, so we will use the tangent ratio again:
and
50tan(28) = y so
y = 26.59. Therefore,
x + y = 55.53 + 26.59 and
the height of the taller building is
82.1 m
Answer:
x=30
Step-by-step explanation:
3(x+2)^3/5 +3=27
Subtract 3 from each side
3(x+2)^3/5 +3-3=27-3
3(x+2)^3/5 =24
Divide by 3
3/3(x+2)^3/5 =24/3
(x+2)^3/5 =8
Take everything to the 5/3 power to get rid of the exponent on the left side
(x+2)^3/5 ^ 5/3=8 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)^(3/5 * 5/3)=8 ^ 5/3
(x+2)=8 ^ 5/3
Replace 8 with 2^3
(x+2)=2^3 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)=2^(3 * 5/3)
x+2 = 2^5
x+2 = 32
Subtract 2 from each side
x+2-2 = 32-2
x=30
