Answer:
90 minutes
Step-by-step explanation:
Hey, there! This is a walking together question, let’s walk through it together.
Firstly, we assign a value for the volume of the swimming pool. Let’s say this is x m^3
While working together, their rate is x/30
Now, for the larger hose, it takes 45 minutes. The rate here is x/45. To find the rate at which the smaller hose takes, we simply subtract the rate of the larger hose from that of both while working together.
Mathematically this is x/30 - x/45 = 15x/1350
Now to calculate the time taken, we simply divide the volume by this rate and that is x divided by 15x/1350 or x * 1350/15x = 90 minutes
Answer:
The first choice is correct. ii only.
Step-by-step explanation:
A rigid transformation changes the location of the shape without changing its size. There are three basic rigid transformations: reflections, rotations, and translations.
We are given these properties:
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure.
Let's analyze each choice below:
O ii only
. This is true. The other two properties are non-rigid transformations. Correct
O i and ii
. This is not true. Increasing or decreasing the size of the figure is a non-rigid transformation. Incorrect.
O ii and iii. Changing the shape of the figure is a non-rigid transformation. Incorrect.
O i, ii, and iii. Properties i and iii are non-rigid transformation. Incorrect.
Answer:
2665 miles in 13 hours, the rate is 205 mph.
Step-by-step explanation:
410/2 is 205 mph. 205 mph * 13 hours is 2665 miles.
Answer:We know that the dilation transformation of a figure either shrink or expand the original figure depending on the scale factor of the dilation.
As here we have scale factor=3>1.
Hence, the dilation changes the original will expand the original figure.
Hence, each of the coordinate of a figure get multiplied by 3.
Hence, the co
ordinates of the image are given as:
i.e. A(0,0) → A'(0,0)
B(2,3) → B'(6,9)
C(1,-2) → C'(3,-6)
D(-3,-3) → D'(-9,-9)
