Hi again! ;)
If we want to find the surface area of a cube, we need to find the area of one surface first, and then multiply that by 9, since there are 9 sides/surfaces on a cube.
Since each side of a square is the same, we first find the area of one surface:
9 × 9 = 81
Then, to find the surface area, we multiply 81 by 6:
81 × 6 = 486
The surface area is
Answer with Step-by-step explanation:
We are given that
Flat fee of taxicab=$7
Cost of one mile=$1.25
1.We have to show that relationship between total cost and the number of miles driven.
2.We have to find independent variable and dependent variable
3.We have to write an equation to model the relationship and make a table to show the cost of 4 to 10 miles.
1.Let x be the number of miles driven by taxicab and total cost y of taxicab.
According to question
This is a relation between number of miles drive and total cost.
2. Independent variable : It is that variable which does not depend on value of another variable .
Dependent variable : it is that variable which depend on value of another variable.
We can see that y depend on x and value of x does not depend on any value.
Therefore, y is dependent variable and x is independent variable.
Substitute x=4 then we get
$12
Substitute x=5 then get
$13.25
\$14.5
$15.75
$17
$18.25
$19.5
4x80=320
Work:
4x8 = 32
(4+4+4+4+4+4+4+4)
Now carry the 0 and you get 320

Given that Alexi and Tony own a food truck that serves only two items, Street tacos and Cuban sandwiches, given that Alexi can make 80 street tacos per hour but only 20 Cuban sandwiches and Tony can make 100 street tacos or 30 cuban sandwiches.
<span>Suppose
that alexi spent all 20 hours of his time on street tacos, he will make a total of 20 x 80 = 1,600 street tacos and tony
spent 17 hours on cuban sandwiches and 3 hours on street tacos, he will make a total of 17 x 30 = 510 cuban sandwiches and a total of 3 x 100 = 300 street tacos.
Combined
they would produce a total of 1,600 + 300 = 1,900 street tacos and 510
cuban sandwiches.</span>
