The area for a trapezoid is A = 1/2 h (base 1 + base 2).  You have the top base of 8.  But straight down underneath that is also a base of 8.  Next to that 8 you have a 4, so thus far you have a bottom base of 8 + 4.  But you're missing what's over on the left.  That base measure of that triangle is also 4, because the triangles are congruent.  So the whole bottom base is 4 + 8 + 4 = 16.  Now you have everything you need:  A = 1/2 (6) (8 + 16).  Do the addition inside the parenthesis first to get 24.  Now multiply that by 6 to get 144.  Now finally, divide that by 2 to get 72 cm^2

A seven digit phone number consists of a three-digit prefix followed
Svetlanka [38]

10000 different phone numbers are possible for a  particular prefix if repetion of digits is allowed

5040 different phone numbers are possible for a  particular prefix if repetion of digits is not allowed

<em><u>Solution:</u></em>

Given that,

A seven digit phone number consists of a three-digit prefix followed  by four digits

We have to find the different phone numbers are possible for a  particular prefix

For a paricualr prefix, there are four digits

Total numbers from 0 to 9 are 10

Therefore,

Different ways for phone number for particular prefix:

If repetition is allowed:

Different ways = 10 x 10 x 10 x 10 = 10000 ways

If repetition is not allowed then:

Different ways = 10 x 9 x 8 x 7 = 5040 ways

Elizabeth bought $5.00 worth of candy at the convenience store. She bought ten more 6-cent salt-water taffies than 10-cent taffi
svp [43]

Answer: 20 6-cents, 30 8-cents, 10 10-cents and 2 20- cents

Step-by-step explanation:

6 cent = x+10

10 cent= x

8 cent= 3x

20 cent=2

6x+60+10x+24x+40

400 divided by 40=X

x=10.

10+10=20/ 6 cents

3x10=30/ 8 cents

x=10/ 10 cents

20 cents= 2.
