Mathematics

Answer:

314 in²

Step-by-step explanation:

The formula for the area of a circle is pi*r² or pi (3.14...)* radius²(squared).

If you plug in the radius given into the equation, you get 3.14*10²  you can then solve this using systems of equations.

3.14*10²

10² = 10*10

3.14*(10*10)

10*10= 100

3.14*100

3.14*100= 314

Answer:

D) 130 workers

Step-by-step explanation:

We have the equation, <em>y = 2x + 40</em>, and <em>y, 300</em> (since the y-coordinate represents the # of bottles made), so we can solve for x, <em>the number of workers needed</em>.

Substitute: <em>300 = 2x + 40</em>

Subtract: <em>260 = 2x</em>

Divide: <em>x = 130</em>

Since x = 130 when y = 300, 130 workers are required to make 300 bottles in a day.

The area of a rectangle garden is 2g^2+34g+140. If the width is 2g+14 what is the length?
ASHA 777 [7]
We know  that
[area of rectangle]=length*width
area=2g²<span>+34g+140
</span><span>width =2g+14
</span>
step 1
find the roots of 2g²+34g+140

using  a graph tool-----> to resolve the second order equation
see the attached figure
the solution is 
g=-10
g=-7
so
2g²+34g+140=(2g+14)*(g+10)

therefore

the length is (g+10)

the answer is
the length is (g+10)
