Answer:
21
Step-by-step explanation:

M=-3.5+2t, R=-3t when they meet M=R so
-3.5+2t=-3t
-3.5+5t=0
5t=3.5
t=0.7 hrs (42 minutes)
Answer:
4/9 is the answer
Hope it correct and it helps
Answer:
Step-by-step explanation:
We are given the following in the question:
Volume of cake = 351 cubic inches
Let x inches be the width of cake.
Width of cake, w =

Then, length of cake,l =

Height of cake,h =

Volume of cake = Volume of cuboid

Putting values, we get:

Thus, dimensions of cake are:

Using it's concept, it is found that the range of the function is given as follows:
.
<h3>What is the range of a function?</h3>
The range of a function is the set that contains all possible output values for the function. In a graph, the range is the set that contains the values of y.
In this graph, the extremes are at y = 0 and y = 7, and the diagonal line crosses as values in this interval, as shown in the graph at the end of the answer, hence the range of the function is given as follows:
.
