Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.

Considered as it only taking the area of flat surfaces of a 3D object, no

Max is paid a salary of $225 a week plus %2.5 commission on his total sales. What was max's total sales for the week if he made

torisob [31]

So we know he made 4,650 of sales and we need 2.5% of that

First to find 2.5% of 4650 we could do

x/4650 = 2.5/100
Cross multiply to get

100x = 11625
x = 116.25

So his salary for this week would be 225 + 116.25 = 341.25

The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). The mon

kkurt [141]

The monthly cost will be $17.14

Step-by-step explanation:

Given that the monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes) then this can be presented in a table form as;

Time in minutes (x) Cost in dollars (y)

50 $12.55

102 $ 17.23

Take the values as ordered pairs to represent coordinates for points that satisfy the linear function

(50,12.55) and (102,17.23)

Finding the slope of the graph using these points

slope,m=Δy/Δx

m=Δy=17.23-12.55 =4.68

Δx=102-50=52

m=4.68/52 =0.09

Finding the equation of the linear function using m=0.09, and point (50,12.55)

m=Δy/Δx

0.09=y-12.55/x-50

0.09(x-50)=y-12.55

0.09x-4.5=y-12.55

0.09x-4.5+12.55=y

y=0.09x+8.05

So for 101 minutes , the cost will be;

y=0.09*101 +8.05

y=9.09+8.05 = $17.14

Evan has a gift card with a balance of $345.09. He used the card to buy a shirt for $17.97.

Jlenok [28]

when he bought the shirt it brought his card balance to $327.12 and then he split the remaining balance with is brother Jack so you would divide $327.12/2 which is $163.56, so they both got $163.56 after he splits
