Answer:
y-intercept: -4, slope: -3/2 or -1.5
Step-by-step explanation:
The point where the line goes through the y axis has y coordinate of -4 so that is the y-intercept.
The line goes down 3 units every 2 units to the right. The slope is rise over run, so that makes the slope -3/2.
Answer:
W=0.8333*t
2.917 ft³
Step-by-step explanation:
At time t=3, there is 2.5 ft³ of water in the tub
Finding the relation will be;
3=2.5
1=?
Rate=0.8333 ft³/min
W=0.8333 ft³ / min
W=0.8333*t
At t=3.5 will be;
1 min = 0.8333
3.5 min =?
Apply cross-production
3.5*0.8333 =2.917 ft³
The amount that Cocoa cups normally charge for a cupcake is $2.50.
The principal was given a discount for each cupcake. The discount costs $0.60. This means that the cost of each cupcake cost was reduced by $0.60.
In order to determine the normal charge for a cupcake, the first step is to determine the discounted cost for one cupcake.
Discounted cost for one cupcake = total discounted cost for for 50 cupcakes / 50
$95 / 50 = $1.90
The normal price for one cupcake can be determined using this formula:
normal price = discounted price + discount given
$1.90 + $0.60 = $2.50
