Answer:

d = 24

Step-by-step explanation:

The area of a circle is given by A = π * r²

We are told the area of the clock is 144π.

Let's clear the formula for the radius:

r² = A / π

r² = 144π / π

r² = 144

r = √144

r = 12

The diameter is two times the radius, d = 2r = 2*12 = 24.

Perform the operation and reduce the answer fully. 5/3 divided 7/4​
Archy [21]

\frac{5}{3}/\frac{7}{4} = \\\\ \frac{5}{3}*\frac{4}{7} =\\ \\ \frac{5*4}{3*7} =\\ \\ \frac{20}{21}


Therefore, 20/21 is the answer.

Solve it plz 29x < 38x + 18
storchak [24]

Answer:

x= -2

Step-by-step explanation:

The first thing I did was isolate the x's on one side.  I subtracted 38x from both sides.  This gives me:

-9x=18.  

Now i divide both sides by -9.  Giving me x=-2

Answer for Question 1 is option 2  

Answer for Question 2 is option 3  

Answer for Question 3 is option 3  

Step-by-step explanation:  

For question 1 by plotting the two points we get the coordinates as (-2, 3) and (2, 1) where the x values are -2, 2 and the y values are 3, 1 respectively.  By substituting values of x in the formula given we get that equation 2 satisfies the values of y as in the graph.  

For question 2 the plotted line is split into two parts where one half is for values of x <2 and the other half is for values of x>2. By finding out the coordinates we get them as (2,-2), (1,-2.5) and (0,-3) for x<2 and by substituting the values of x in the formula we get option 3 as our answer.  

For question 3 we need to find the value of y when x=3 and the first condition is only for values greater than 3 so we take the second condition and substitute the value of x=3 and we get the value of y as 5 so the answer is option 3
