Terrence is folding paper cranes at a constant rate. Write an equation to describe the relationship between c, the number of cra

nes, and t, the total time in minutes
Mathematics
1 answer:
Vanyuwa [196]3 years ago
7 0

Answer:

It is c = kt.

Step-by-step explanation:

This is direct variation . As the time increases the number of cranes increases.

The equation is c = kt  where k is the constant  of variation.  In this case it will be a positive value because c is increasing with time.

If they make 20 cranes in 10 minutes then we can find the value of k by plugging in these values;

20 = k * 10

g = 20/10

k = 2.

So they make 2 cranes per minute.

What is the factored form of the expression?<br><br> 16b^2 – 81
solong [7]

Answer:

(4b-9) (4b+9)

Step-by-step explanation:

16b^2 – 81

This is the difference of squares

(a^2 -c^2) = (a-c) (a+c)

a^2 = 16b^2   so a= 4b

c^2 = 81   so c = 9

(16b^2 – 81) = (4b-9) (4b+9)

If f(x) is the floor function, which answer shows the graph of g(x)=f(x+1)?
Svetach [21]

The floor function is the function that takes as input a real number x and gives as output the greatest integer less than or equal to x

Then it shapes like a stairs

Its starting points are black circles and its ending points are empty circles

The middle one is a line of length 1 unit starting from 0 to 1 [(0, 0), (1, 0)]

Since g(x) = f(x + 1)

That means we will move f(x) 1 unit to the left (subtract x-coordinate by 1)

Then the points (0, 0) [black point] and (1, 0) [empty point] will change to (-1, 0) [black point] and (0, 0) [empty point]

Let us look at these graphs and find the correct one

This is the correct answer because

It has a black circle at (-1, 0) and an empty circle at (0, 0)

This is the original figure of the floor function f(x)

Then when we translate it 1 unit to the left, every black point will move 1 unit to the left

Then the point (0, 0) will be (-1, 0) and the point (1, 0) will be (0, 0), then the correct option should be

Area is 180,length is 1 1/4,what is the width
rusak2 [61]
180 is the area and the length is 1.25 so we need to find the width. We need to divide 180/1.25 which is 144.
144*1.25 is 180
The width is 
144
