Find the area [ a = bh ] of both then subtract.

16 * 20 = 320

11 * 14 = 154

320 - 154 = 166"

Best of Luck!

Help please its math

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.

a motorboat traveling with a current can go 160km in 4 hours. against the current it takes 5 hours to go the same distance. find

irakobra [83]

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 = $\frac{Distance}{Time}$

x+y = $\frac{160}{4}$

x+y = 40 Eqn 1

x-y = $\frac{160}{5}$

x-y = 32 Eqn 2

Adding Eqn 1 and Eqn 2

$(x+y)+(x-y)=40+32\\x+y+x-y=72\\2x=72$

Dividing both sides by 2

$\frac{2x}{2}=\frac{72}{2}\\x=36$

Putting x=36 in Eqn 1

$36+y=40\\y=40-36\\y=4$

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