Answer:
- 9
Step-by-step explanation:
2/3 x - 4 = -2
2/3 x = -2+4
x = 6 * (-3/2)
9 = -9
Answer:
Step-by-step explanation:
Let x = base measurement; then height = (x-4).
A = ½•base•height 48 = ½x(x-4
Answer:
76.25°
Step-by-step explanation:
The solution to the differential equation is an exponential curve with a horizontal asymptote at Tm. It passes through (0, 145) and (30, 95), so the equation can be written as ...
T = 80 +65((95-65)/(145-65))^(t/30)
T = 80 +65(3/8)^(t/30)
That is, the temperature difference is reduced to 3/8 of its original value in 30 minutes.
Since the coffee in cup B cools twice as fast, it will cool to the same temperature (95°) in 15 minutes. In the next 15 minutes, the temperature difference will be reduced to (3/8)^2 of the original 80°, so will be 11.25°. That is, the temperature of cup B will be ...
11.25° +65° = 76.25°
after 30 minutes.
Answer:
7x + 2y = 9
Step-by-step explanation:
standard form is always written as:
Ax + By = C
Answer:
total surface area of cube is <u>6 * area of one side</u>
therefore area of one side is given 64cm^2
thickness is also given 5cm .
TSA is 64*5 = 320cm^2
