Answer:

\rightarrow \frac{a^{-1}}{b^{-1}\times \sqrt{a}}\\\\\rightarrow \frac{a^{-1}}{b^{-1}\times a^{\frac{1}{2}}}\\\\\rightarrow a^{-1-\frac{1}{2}} \times b^1\\\\=a^{\frac{-3}{2}} \times b\\\\\rightarrow ca^pb^q=a^{\frac{-3}{2}} \times b\\\\c=1\\\\p=\frac{-3}{2}\\\\q=1

So the problem ask to calculate and covert the said equation or expression to the form of ca^pb^q where as all of the variables is a number. So base in that information and following some formula, the answer would be a^(-3/2)b. I hope you are satisfied with my answer

Help please i’m confused
morpeh [17]

Answer:

7/10 pi (radians)

Step-by-step explanation:

The formula for sector area is (angle * r^2)/2

140pi = angle*r^2/2

multiply both sides by 2

280pi = angle * r^2

r = 20 cm (substitute)

280pi = angle * (20)^2

280pi = angle * 400

Divide both sides by 400

7/10 pi = angle

At a sporting event, the price for 3 cheeseburgers and 2 cups of lemonade is $14 and the price for 2 cheeseburgers and 4 cups of
crimeas [40]
C= the price of a cheeseburger and l = the price of a lemonade:

3c + 2l=14\\2c+4l=12

Divide the second equation by -2 to begin the process of solving by elimination:

3c + 2l=14\\-1/2\ (2c+4l=12)\\\\3c+2l=14\\-c-2l=-6\\\\2c=8\\c=4

Now that we have c, 4, we can plug it in to one of the equations to find l:

3c + 2l=14\\3(4)+2l=14\\12+2l=14\\2l=2\\l=1

So, each cheeseburger is $4 and each lemonade is $1.  The final answer is:

1 cheeseburger and 2 cups of lemonade would cost $6.

makvit [3.9K]
The first clue to this problem is that Bob has three kids in which the product of their ages is 72 and the sum is 14. From the factor tree, there  are two combinations of the ages  2, 6, 6 and<span>  3,3,8. Last thing he said is that his youngest is named Justice. One combination has similar number in the set which means there are twins. The youngest means there can be only one child. Hence the ages of the children are 2,6,and 6. </span>

Which is an equivalent expression for 21a+35?
ki77a [65]

Answer:

7(3a + 5)

Step-by-step explanation:

Rewrite 21 as 7 · 3

Rewrite 35 as  7 · 5

Therefore,

⇒ 21a + 35 = 7 · 3a + 7 · 5

Factor out common term 7:

⇒ 7 · 3a + 7 · 5 = 7(3a + 5)
