Step-by-step explanation:
Rewrite in slope-intercept form.
The slope-intercept form is
y = m x + b , where m is the slope and b is the y-intercept. y = m x + b
Reorder 2 and 2 x . y = 2 x + 2
Use the slope-intercept form to find the slope and y-intercept.

An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min, at what rate is water (in ft3/min) draining from the tank when the water depth is 8 ft
Answers
Answer:
dhdt≃0.283ft3s
Step-by-step explanation:
dhdt≃0.283ft3s
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min.
[tex]\rm \dfrac{dV}{dt} = -1 \ ft/min[/tex]
The volume of the cone is given as,
V = (1/3) πr²h
The relation between r and h is given as,
r / h = 3 / 12
r = h / 4
Then the volume is written as,
V = (1/3) π (h/4)² × h
V = (π / 48) h³
Differentiate the volume with respect to time. Then we have
(dV)/(dt) = (π/48) x 3h² x (dh / dt)
- 1 = (π/48) x 3(4)² (dh / dt)
- 1/π = dh / dt
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.

Find the area of the unshaded region in Fig, where ABCD is a square of side 20 cm and semicircles are drawn with each side of the square as diameter. (Use π = 3.14)
Answers
Answer:
229
Step-by-step explanation:
Area of square is = 20 * 20 = 400
radius = 20 / 2 = 10
Area of semi circle is = 1/2 * πr²
= 1/2 * 3.14 * 10²
= 1/2 / 314
= 157
assume there are four shaded regions for the figure
Area of 4 semicircles−Area of shaded region=Area of square ABCD
Area of shaded region=Area of 4 semicircles−Area of square ABCD
= 4 * 157 - 400
= 628 - 400
= 228
so each single shaded area is 228/4
= 57
now in your problem there are 3 shaded regions like this
so area of unshaded region is =
Area of square - 3 * shaded region area of one region
=> 400 - 3 * 57
=> 400 - 171
=> 229

You and a group of friends are going to a five-day outdoor music festival during spring break. You hope it does not rain during
the festival, but the weather forecast says there is a 50% chance of rain on the first day, a 25% chance of rain on the second day, a
20% chance of rain on the third day, 5% chance of rain on the fourth day, and a 10% chance of rain on the fifth day.
Assume these probabilities are independent of whether it rained on the previous day or not.
What is the probability that it does not rain during the entire festival?
%
(Round to 2 decimal places)
Answers
Answer:
Below in bold
Step-by-step explanation:
The probability that it doesn't rain is 1 - probability it does ( Prob written as a fraction). So for the first day Probability of not raining = 1 - 0.50 = 0.50.
So the probability of it not raining the entire festival
= 0.5 * 0.75 * 0.80 * 0.95 * 0.90
= 0.2565
or 25.65%

Step-by-step explanation:
The number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclistsLet x represent the number of cyclists.Since, the activists receive $60 per cyclist entry and $15,000 in donations, hence:Revenue = 60x + 15000Also, the cost of the race is $18 per entry, hence:Cost = 18xThey need to raise at least $57,000, hence:Profit ≥ 57000Revenue - Cost ≥ 57000(60x + 15000) - 18x ≥ 5700042x ≥ 42000x ≥ 1000Therefore the number of cyclists the group needs to raise at least $57,000 must be at least 1000 cyclistsAT&T offers a deal for internet service that is $20 a month.

Use an equation to find the value of k
so that the line passing through (−4,k)
and (6,−7)
has a slope of −15
Answers
Answer: k=143
Step-by-step explanation:
Let's start with the standard form of a linear equation: y = mx + b, where m ios the slope and b is trhe y-intercept (the value of y when x=0). We know the slope, so:
y = -15x + b
We can find the y-intercept, b, by using the one given point (6,-7) in the equation and solve for b:
y = -15x + b
-7 = -15(6) + b
-7 = -90+b
b = 83
The equation is y = -15x + 83
Use the x value of (-4,k) to find y, which will be k.
y = -15x + 83
y = -15(-4) + 83
y = 60 + 93
y = 143
k is 143

Answers
Answer:
$60 for adults (x), $24 dollars for children (y)

Solve using systems of equations
3x + y = $204
2x + 3y = $192
y = 204 - 3x
2x + 3( 204 - 3x) = 192
2x + 612 - 9x = 192
-7x + 612 = 192
420 = 7x
x = $60 for adults
y = 204 - 3(60)
