Answer:
18 cm²
Step-by-step explanation:
All sides of a rhombus are the same length (as shown by the markings), so one side is 1/4 of the perimeter:
(24 cm)/4 = 6 cm . . . . side length
As with all parallelograms, the area is the product of the side length and the height perpendicular to that side:
A = (6 cm)(3 cm) = 18 cm²
It has an area of 18 cm².

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.

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%

Fraction of students that opted for French = [tex]\frac{4}{15}[/tex]
The total number of students = 150
Fraction of students that opted for German = [tex]\frac{2}{5}[/tex]
Fraction of students that opted for Italian = [tex]\frac{1}{3}[/tex]
Fraction of students that opted for French = 1 - Fraction of students that opted for German - Fraction of students that opted for Italian

2. A group of activists wants to raise money for a good cause, so they decide to sponsor a bicycle race. It receives $60 per cyclist entry and $15,000 in donations, but it must spend $18 per entry to cover the cost of the race.
Write and solve an inequality to determine the number of cyclists the group needs to raise at least $57,000. Be sure to define a variable and explain what your answer means in the context of the problem.
Answers
Answer
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 cyclistsUse 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)
Step-by-step explanation:
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)
y = $24 for children

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.
