Three of the kids on the tilt-O-Whirl threw up when they got off the ride. This is one-fifth of the kids on the ride. Write an equation that represents the number of kids on the ride. .-. This is kind of a weird question
Answer:
3 is 1/5 so 3*5 is how many kids are on the ride.
3 * 5 = 15. There are 15 kids on the ride, but the question's answer would just be 3*5.

convert 4/5 to a percent 
Answer:
80%
Step-by-step explanation:
Answer:
80%
Step-by-step explanation:
Solve tan x =cot x for 0 < x < pi
tan(x) = cot(x)
tan(x) = 1 / tan(x)
tan²(x) = 1
tan²(x) - 1 = 0
(tan(x) - 1) (tan(x) + 1) = 0
tan(x) - 1 = 0 or tan(x) + 1 = 0
tan(x) = 1 or tan(x) = -1
x = π/4 + nπ or x = -π/4 + nπ
where in both cases, n is any integer.
In the interval 0 < x < π, we get solutions:
• x = π/4 from the first family (when n = 0)
• x = 3π/4 from the second family (when n = 1)
So the equation has solutions x = π/4 or x = 3π/4.

(Answer is 32) For the inverse variation equation p = 8/V, what is the value of p when V = 1/4 ?
1/32
1/2
2
32 <—— this is the correct answer!
Answer:
p = 32
Step-by-step explanation:
Given expression:
p = [tex]\frac{8}{v}[/tex]
Since v = [tex]\frac{1}{4}[/tex]
Now insert the parameters and solve;
p = [tex]\frac{8}{\frac{1}{4} }[/tex]
p = 8 ÷ [tex]\frac{1}{4}[/tex]
p = 8 x 4
p = 32

Step-by-step explanation:
A solid object with an initial temperature of 75 degrees Fahrenheit is dropped into a lake with a temperature of 33 degrees Fahrenheit. The function f(t)=Ce(−kt)+33 represents the situation, where t is time in minutes, C is a constant, and k is a constant.
After 2 minutes the object has a temperature of 55 degrees. What will be the temperature of the object, in degrees Fahrenheit, after 4 minutes? Round your answer to the nearest tenth, and do not include units.
Answer: 44.5
Step-by-step explanation:
The object's temperature post 4 minutes in respect to degrees Fahrenheit would be:
- [tex]44.5[/tex]°C
Given that,
Function [tex]f(t)=Ce(-kt)+33[/tex]
where,
t = time in terms of minutes
C = constant
k = constant
The temperature of the object [tex]= 75[/tex]°
where, [tex]t = 0[/tex]
Using the function,
∵ [tex]f (0) = 75[/tex]
[tex]Ce^{(0)}[/tex] [tex]+ 33 = 75[/tex]
This will lead to
[tex]C = 42[/tex] (∵ C being constant)
Temperature post 2 minutes = [tex]55[/tex]°
or
[tex]55 =[/tex] [tex]42e^{(-2k)} + 33[/tex] (k being [tex]0.3233[/tex])
Thus,
Temperature after 4 minutes would be:
[tex]f(4) = 42e^{(-1.29325)} + 33[/tex]
[tex]= 44.5[/tex]°
Thus, [tex]44.5[/tex]°C is the correct answer.

Which graph represents a function, f(x) that has a slope of 3 units and f(0) = 14?
Answer:A
Step-by-step explanation:
Since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.
A linear equation is in the form:
y = mx + b;
where m is the slope, b is the y intercept and y, x are variables.
Since f(0) = 14, hence the y intercept is 14, hence the graph passes through point (0, 14).
Also, since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.
Therefore the graph is attached below.

The number 4 + i is multiplied by some real number to yield 2 + one-half i. Which equation is true?
Answer:
A. (1/2)(4+i)= 2+ (1/2)i
Step-by-step explanation:
The equation 1/2(4+i) = 2+(1/2)i is the transformation if we multiply the complex number 4 + i with 1/2 option first is correct.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have a complex number:
= 4+i
Multiply it by 1/2
[tex]= \rm \dfrac{1}{2}(4+i)\\\\\rm =2+ \dfrac{1}{2}i[/tex]
[tex]\rm \dfrac{1}{2}(4+i) =2+ \dfrac{1}{2}i[/tex]

Step-by-step explanation:
Properties of Logarithms
We'll recall below the basic properties of logarithms:
[tex]log_b(1) = 0[/tex]
Logarithm of the base:
[tex]log_b(b) = 1[/tex]
Product rule:
[tex]log_b(xy) = log_b(x) + log_b(y)[/tex]
Division rule:
[tex]\displaystyle log_b(\frac{x}{y}) = log_b(x) - log_b(y)[/tex]
Power rule:
[tex]log_b(x^n) = n\cdot log_b(x)[/tex]
Change of base:
[tex]\displaystyle log_b(x) = \frac{ log_a(x)}{log_a(b)}[/tex]
Simplifying logarithms often requires the application of one or more of the above properties.
Simplify
[tex]\displaystyle log_\frac{1}{2}(64)[/tex]
Factoring [tex]64=2^6[/tex].
[tex]\displaystyle log_\frac{1}{2}(64)=\displaystyle log_\frac{1}{2}(2^6)[/tex]
Applying the power rule:
[tex]\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}(2)[/tex]
Since
[tex]\displaystyle 2=(1/2)^{-1}[/tex]
[tex]\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}((1/2)^{-1})[/tex]
Applying the power rule:
[tex]\displaystyle log_\frac{1}{2}(64)=-6\cdot log_\frac{1}{2}(\frac{1}{2})[/tex]
Applying the logarithm of the base:

Write an equation of the line that passes through (-2,3) and is parallel to the line y = 2x – 4.
Answer:
The parallel line should be y = 2x + 7
The equation of the line that passes through the point (8,-1) and is parallel to the line y = 2x – 4 is; y = 2x + 7
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given If the line is parallel to the line resembling the equation y = 2x - 4, it would mean that the line would have a similar slope,
m= 2
We know that Point-Slope Form:
y - y₁ = m(x - x₁)
Point (-2,3)
Then Slope m = 2
Now Write the equation as;
y - 3 = 2(x + 2)
This means the final equation is;
y = 2x + 7

a car travels at a rate of 120 kilometer per hour if 1 mile equals 1.6 kilometer which equation could be used to find the number of miles the car travels per hour ?
Answer:
75
Step-by-step explanation:
120 ÷ 1.6 = 75 since 1.6 kilometer per hour is 1 mile, the car travels 75 miles per hours
Answer:
The car travels 75 miles per hour
Step-by-step explanation:
Units of Length
The most common units of distance are millimeters, centimeters, meters, miles, and kilometers.
The equivalence from miles to kilometers is:
1 mile = 1.6 Kilometers
If we wanted to convert a given distance from kilometers to miles, we'd need to divide by 1.6, that is:
d(miles) = d(km)/1.6
The above equation can be used to find the number of miles given the number of kilometers.
If a car travels at 120 kilometers per hour, then in one hour it travels
d(km)=120
Thus, the distance in miles is:
d(miles) = 120/1.6 = 75
The car travels 75 miles per hour
Find the appropriate side length of a square game board with an area of 175 inch squared
Answer:
13.29 inch
Step-by-step explanation:
Given:
Square game board.
Area of square game board = 175 sq inch
To find:
The side length of the square board game.
Solution:
First of all, we need to know the formula for area of a square.
Let us have a look at the formula for area of a square.
[tex]Area = Side\times Side[/tex]
OR
[tex]Area = Side^2[/tex]
Putting value of area = 175 sq in and let us find the value of Side.
[tex]175=Side^2\\\Rightarrow Side = \sqrt{175}\\\Rightarrow Side \approx \bold{13.29\ inch}[/tex]
Therefore, the answer is:
The appropriate side length of the square game board = 13.29 inch
