Find the amount of interest payable if $400 is borrowed at 14% interest and is to be repaid in 6 months
Shtirlitz [24]

Answer:

The amount of interest payable after 6 months is $28.

Step-by-step explanation:

Here, the Principal amount  borrowed = $400

Rate of Interest  = 14%

Time = 6 months  = 6 / 12 years  = 0.5 year

Now, SIMPLE INTEREST = \frac{P \times R \times T}{100}

So, here SI  = SI = \frac{400 \times 14 \times 0.5}{100}   =  28

or, SI = $28

Hence, the amount of interest payable after 6 months is $28.

I need help asap plz!!!​
svet-max [94.6K]

Answer:

AC ≈ 10.3

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan48° = \frac{opposite}{adjacent} = \frac{AC}{AB} = \frac{AC}{9.3} ( multiply both sides by 9.3 )

9.3 × tan48° = AC , then

AC ≈ 10.3 ( to 3 sf )

In trapezoid WXYZ, identify WX. PLEASE HELP!!!
matrenka [14]

Answer:

The length of WX is 31 units.(third option)

Step-by-step explanation:

Given that In trapezoid WXYZ, WX║ZY and S and T are the mid points of the sides WZ and XY. We have to find the length of WX.

By trapezoid mid-segment Property,

A mid-segment of a trapezoid join the midpoints of the two non-parallel sides of trapezoid. The length of the mid-segment is the average of the lengths of the two bases and is parallel to the bases of the trapezoid.

∴ ST=\frac{WX+ZY}{2}

⇒ 48=\frac{WX+65}{2}

⇒ 96=WX+65

⇒ WX=96-65=31

The length of WX is 31 units.(third option)
