Answer:
The middle slab is 2 cubic feet.
Step-by-step explanation:
The problem presents the information: Mr. Alvarez makes a walkway out of 3 cement slabs.
However, he uses 14 Cubic feet of cement to make the walkway. Each square slab has a volume of 4 cubic feet.
Mr. Alvarez makes the way with 3 cement slabs (NC), each cement slab is 4 cubic feet (UC). It means, the cubic feet for the 3 cement slabs (CS) are:
CS = NC* UC = 3*4 = 12 cubic feet.
It means Mr. Alvarez uses 12 cubic feet with 3 cement slabs.
Mr. Alvarez used in total of 14 cubic feet of cement (TC). At this moment he used 12 cubic feet of cement (CS). It means, there will be a part of the cement slab used (PC).
PC = TC - CS = 14 - 12 = 2 Cubic feet.
Finally, the middle slab is 2 cubic feet of cement.

Answer:
Step-by-step explanation:
g(x) = (5/8)^x is an exponential function. Because 5/8 is less than 1, this function decreases constantly. You should start with "easy" values of x, such as 0, 1, 1/2, and calculate the corresponding y-values.
x y = (5/8)^x Plot these points:
0 1 (0, 1)
1 5/8 (1, 5/8)
2 25/64 (2, 25/64)
10 0.009 (10, 0.009
-1 1.6 (-1, 1.6)
Observe that the y-intercept is (-1, 1.6), and that as x increases, the y values decrease. As x grows larger and larger, the curve of the graph approaches the x-axis. We call that axis the "horizontal asymptote).
Answer:
a) Veronica earns $276. Francis earns $216
b) $6000
Step-by-step explanation:
Veronica's income would be I= 0.035s +150 where I is income and s is sales while Francis's income would be 0.06s. So for $3600 in sales Veronica earns $276 while Francis earns $216. To find the answer to part b just set the two equations equal to each other and solve for x. so 0.035x + 150 = 0.06x Subtracting 0.035 x from both sides gives 150 = 0.025x. Dividing both sides by 0.025 gives x = $6000
