8 x $9 = $72.00
8 x $3 = $24.00
$72.00 + $24.00 = $96.00
savings changed by $96.00
Answer:
6 toppings
Step-by-step explanation:
The t in this equation represents the amount of toppings.
22 + 0.65t = 26
-22 -22
0.65t = 4
0.65t/0.65 = 4/0.65
t = 6
They could get 6 toppings and the total would be $25.90.
Answer:
The time taken by object to travel 21 ft is 1 sec
Step-by-step explanation:
The distance travel by falling object given as
d = 5 t + 16 t²
The Distance cover by object to travel = 21 ft
so , from Distance time equation
21 = 5 t + 16 t²
or, 16 t² + 5 t - 21 = 0
Or, 16 t² - 16 t +21 t - 21 = 0
Or, 16 t ( t - 1) + 21 (t - 1) = 0
Or. (t - 1) (16 t + 21) = 0
Or, (t - 1) = 0 And (16 t + 21) = 0
∴ t = 1 And t = (
)
Hence The time taken by object to travel 21 ft is 1 sec Answer
You could find the need of pine board by finding the perimeter of the frame. But first you need to equalize the units, because one of them is in feet and the other one is in inches.
18 inches = 18/12 feet
18 inches = 1.5 feet
perimeter = l + w + l + w
perimeter = 2 + 1.5 + 2 + 1.5
perimeter = 7
The perimeter is equal to 7 feet, therefore Carl needs 7 feet of pine board
