Answer:
- partial products: 0.25, 1.5, 0.50, 3
- Zoe spent $5.25 on apples
Step-by-step explanation:
The partial products are apparently derived by multiplying parts of each value on either side of the decimal point:
1.5 × 3.50 = (1 + 0.5)(3 + 0.50) = 1×3 + 0.5×3 +1×0.50 +0.5×0.50
= 3 + 1.5 + 0.50 + 0.25 . . . . . partial products
Their sum is ...
3 + 1.5 + 0.50 + 0.25 = 5.25
Zoe spent $5.25 on apples.
The speed of motorboat is 36 kmph and speed of current is 4 kmph.
Step-by-step explanation:
Distance covered in 4 hours = 160 km
Time took on return trip = 5 hours
Let,
x represent the speed of boat.
y represent the speed of current.
Combined speed of boat and current when in same direction = x+y
Speed of boat and current when travelling against = x-y
Distance = Speed * Time
Speed = 
x+y = 
x+y = 40 Eqn 1
x-y = 
x-y = 32 Eqn 2
Adding Eqn 1 and Eqn 2

Dividing both sides by 2

Putting x=36 in Eqn 1

The speed of motorboat is 36 kmph and speed of current is 4 kmph.

Answer:
y=-12x-9
Step-by-step explanation:
plug the value of m and b in the equation:
-y=12x+9
divide negative 1
y=-12x-9
Answer:
As shown in picture, shaded space area:
A = outer rectangle area - inner rectangle area
= 11 x 8 - 9 x 6
= 88 - 54
= 34 (yd2)
