Find the area of the composite figure Hint: A(rectangle)=lw

Alanna is painting a border on a wall. The border consists of kite-shaped figures as shown. mc022-1.jpg Each kite measures 6 inc

Sedaia [141]

the question does not present the picture, but this does not interfere with the resolution

step 1

Find the area of a kite

we know that

area of a kite=(1/2)*[d1*d2]

where d1 and d2 are the diagonals

so

area of a kite=(1/2)*[6*12]-----> 36 in²

The wall is 12 feet across-----> convert to in-----> 12*12----> 144 in

step 2
find the number of kite to paint
divide across of the wall to across of a kite
144/6-----> 24

step 3
find the number of square inches of the wall to be covered with comets
24*area of one kite-----> 24*36-----> 864 in²

the answer is 864 in²
Note For this calculation, as there is no drawing we have assumed that the diagonal of the 6-inch kite is horizontal

case b)
If the diagonal of the 12-inch kite was horizontal, then the calculation would be
step 2
find the number of kite to paint
divide across of the wall to across of a kite
144/12-----> 12

step 3
find the number of square inches of the wall to be covered with comets
12*area of one kite-----> 12*36-----> 432 in²

the answer would be 432 in²

Evaluate. Write your answer as a fraction or whole number without exponents. 9^–3 =

juin [17]

Answer:

$\frac{1}{9^3}$ or $\frac{1}{729}$

Step-by-step explanation:

When we have an exponent that is a negative, it is the same thing as 1 over the positive exponent. So, we move 9^-3 into 1/9^3 and then we evaluate the exponent to get our answer.

Jeanette sells hand-painted signs. She earns a $425 weekly salary in addition to $30 for each sign she sells. Write a linear equ

andrew11 [14]

Answer:

$=425+30x$

Step-by-step explanation:

Given:

Fixed salary earned by Jeanette per week = $\$425$

Additional amount earned by her for each sign she sells = $\$30$

To find: linear equation which represents her weekly pay based on the number of signs she sells.

Solution:

Let number of signs sold by Jeanette be x

So, her weekly pay = fixed pay + Additional amount earned by her for each sign she sells

$=425+30x$

Peter also earns a certain amount per hour. The table shows the amount of money, in dollars, he earns in a given number of hours

drek231 [11]

To determine how much you get per hour, divide 44 by 4, 88 by 8, and 132 by 12. Each time you get 11, so you get 11 dollars an hour.

If y = money earned and x = number of hours worked, then

y=11x
because the money you get is 11 times the amount of hours you work.

Hope this helps and I can provide further explanation if needed!
