1 answer:
Answer:
The daily cost of cooling the large warehouse with the same model of air conditioner is
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
In this problem
The scale factor is equal to 2.5
so
The scale factor elevated to the cube is
To estimate the daily cost of cooling the large warehouse with the same model of air conditioner, multiply $125.00 by the scale factor elevated to the cube

Choose the option that is most likely to the shape on the question.
Answer:
See below.
Step-by-step explanation:
First, factor the numerators and the denominators:
Now, make the two denominators equivalent. To do this, we can multiply the first term by (z+1) and multiply the second term by 2. This will give us:
Now, combine them since they have a common denominator:
This cannot be simplified further.
Step-by-step explanation:
given
as equation 1, and
as equation 2.
Now, multiply equation 2 by 2.
now let's this equation be equation 3.
We now use equation 1 + equation 3 to eliminate y and find x.
Now substitute x = 7 into equation 2.
