Each of the 17 guinea pigs needs its cage cleaned. If it takes 1 hour to clean 4 cages, how many hours will it take to clean all 17 cages? It will take hours to clean all the cages.
Answer:
Time taken to clean all 17 cages = 4.25 hours
Step-by-step explanation:
Total number of Guinea pig cage = 17
Time taken to clean 4 cage = 1 hour
So,
Time taken to clean 1 cage = [tex] \frac{1}{4} [/tex] hour = 15 minutes
Therefore,
Time taken to clean 17 cages = 17 × 15 minutes = 255 minutes
= [tex] \frac{255}{60} [/tex] hours
= 4.25 hours
Answer:
Time taken to clean all 17 cages = 4.25 hours

A curve is describe by the following parametric equations:
x=3+t, y=t^2-4
Which statement best describes the curve?
A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.
B. The curve is a parabola with a vertex at (3,-4) and is traced from right to left for increasing values of t.
C. The curve is a parabola with a vertex at (-3,4) and is traced from left to right for increasing values of t.
D. The curve is a parabola with a vertex at (-3,4) and is traced from right to left for increasing values of t.
Answer:
A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.
Step-by-step explanation:
x = 3 + t
y = t² − 4
Eliminating the parameter:
t = x − 3
y = (x − 3)² − 4
This is an upwards parabola with a vertex at (3, -4).
x = 3 + t, so as t increases, x increases.
So the curve is traced from left to right.

Which equation represents a proportional relationship that has a constant of proportionality equal to –10? y = x minus 10 y = StartFraction over negative 10 EndFraction y = negative 10 x y = negative 10
Answer:
The correct answer would be C. y = -10x
Step-by-step explanation: We cam eliminate the first two by common sense, that would leave us with options C, and D. The correct answer would be C, the reason it is not D is because D isn't a proportion, y = -10 is just stating that variable y equals -10, whereas, y = -10x represents a proportion.

Which graph shows y= (-5x) -4?
Answer:
Graph A
Step-by-step explanation
I look at the y-intercept first, and the y-intercept is -4, so looking at each graph you can see both A and D have y-intercepts of -4, since the line intercepts, or goes through the y-axis (the vertical line of the graph) at -4.
Then, you look at the variable that's changing, which is -5x. Since it's a negative, A is the graph that is negatively decreasing, because of its position on the graph. The line is going down, starting in the negative side.

Assuming that the shapes are rectangular prisms.
Thomas is building rectangular boxes. The table shows the area in square feet, f(x), of the bottom of a box when one side of the box is x feet long. Choose the function that represents the data. f(x) = x2 + 2x f(x) = 2x2 f(x) = 2x
Answer:

Step-by-step explanation:
A function assigns the values. The correct option is C, f(x)=2x².
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that the table shows the area in square feet, f(x), of the bottom of a box when one side of the box is x feet long. Now, the function that can represent this table can be found by substituting the values in the function and checking if the two sides are equal or not.
A.) f(x)= x²+2x
f(1) should be equal to 2.
f(x)= x²+2x
f(1)= 1²+2(1) = 3
Thus, this is not the correct function.
B.) f(x)= x²/2
f(1) should be equal to 2.
f(x)= x²/2
f(1)= 1²/2 = 0.5
Thus, this is not the correct function.
C.) f(x)=2x²
f(1) should be equal to 2.
f(x)=2x²
f(1)= 2(1)² = 2
Also, f(2) should be equal to 8.
f(x)=2x²
f(1)= 2(2)² = 8
Thus, this is the correct function.
D.) f(x)=2x
f(1) should be equal to 2.
f(x)=2x
f(1)= 2(1) = 2
Also, f(2) should be equal to 8.
f(x)=2x
f(1)= 2(2) = 4
Thus, this is the correct function.
Hence, the correct function that represents the area of the box is f(x)=2x².

Step-by-step explanation:
Median is the middle ( 1 2 3 4 5 the median would be 3)
You start at 2 and end at 27
List all the numbers from 2 to 27 and come from both ends until you get to the middle number(s)
In this case there are two 14 & 15
14+15=29 29÷2=14.5
Since there are no decimal answers you are left with 14
Range you take the two end numbers and subtract them (27 & 2)

Which equation represents a line that passes through (2. - 1/2) and has a slope of 3?
y-2 = 3(x + 1/2)
y-3 = 2(x + 1/2)
y + 1/2 = 3(x - 2)
y + 1/ 2 = 2(x - 3)
Answer:
y + 1/2 = 3(x - 2) This matches the 3rd answer choice.
Step-by-step explanation:
Use the point-slope formula for the equation of a straight line that passes through the point (h, k) and has a slope of m:
y - k = m(x - h) becomes:
y + 1/2 = 3(x - 2) This matches the 3rd answer choice.
The equation of the line will be y + 1/2 = 3(x – 2). Then the correct option is C.
What is the equation of line?The equation of line is given as
y = mx + c
Where m is the slope and c is the y-intercept.
The slope is 3. Then the equation of line will be
y = 3x + c
If the equation is passing through (2, -1/2). Then we have
-1/2 = 3(2) + c
c = -6 - 1/2
Then the equation will be
y = 3x – 6 – 1/2
y + 1/2 = 3(x – 2)
Then the correct option is C.
