Answer:

$1.53

Step-by-step explanation:

Weight of orange = 36 grams

Number of oranges purchased = 10

Total grams of oranges purchased :

Weight per orange * number of oranges

36 grams * 10 = 360 grams

Selling price per kg = $4.25

Price per gram = $4.25 / 1000 = $0.00425 per gram

Selling price of 360 g :

360 * $0.00425

= $1.53

Which expression is a difference of cubes?

Tanzania [10]

Answer:

Option 4 is correct.

Step-by-step explanation:

Given the following options

we have to choose the difference of cubes.

Option 1:

$9w^{33}-y^{12}$

$9(w^{11})^{3}-(y^4)^3$

which is not the difference of cubes

Option 2:

$18p^{15}-q^{21}$

$18(p^5)^3-(q^7)^3$

which is not the difference of cubes

Option 3:

$36a^{22}-b^{16}$

$(6a^{11})^2-(b^8)^2$

which is the difference of square

Option 4:

$64c^{15}-a^{27}$

$(4c^5)^3-(a^9)^3$

which is the difference of cubes.

The radius of a circle is 4 feet. What is the length of a 90° arc? HELP ME PLEASE

Elza [17]

Answer:

6.3feet

Step-by-step explanation:

Given data

Radius= 4feet

The expression for the circumference of a circle is

C= 2πr

Substitute

C=2*3.142*4

C=25.136 feet

Also, a 90° arc is 1/4 of the circumference of a circle

Hence the length of the 90° arc is

=25.136/4

=6.284 feet

=6.3feet
