HELP

Inga [223]

Answer:

3.75 quarts, rounded to 3.8 quarts

Step-by-step explanation:

3 quarts of solution is 10% antifreeze, so 0.3 quarts are already antifreeze, and 2.7 quarts are not.

a(the antifreeze we already have)+x(what we're going to add)= 1.5*2.7

Let me explain. If we have 60% antifreeze, 40% is not. 60/40=1.5

Substitute a for 0.3

0.3+x=4.05 Subtract 0.3 from both sides

x=3.75

Find the equation of a circle with a point at ( 10 , - 4 ) and a point at ( -2 , - 4 )

astra-53 [7]

Answer:

Solution given:

letA=(10,-4)

B=(-2,-4)

centre[C](h,k)= $\frac{10-2}{2},\frac{-4-4}{2}=(+4,-4)$

radius= $\sqrt{(4-10)²+(-4+4)²}=6$ units

we have

Equation of a circle is;

(x-h)²+(y-k)²=r²

(x-4)²+(y+4)²=36

or.

x²-8x+16+y²+8y+16=36

x²-8x+8y+y²=36-32

x²-8x+8y+y²=4

The equation is (x-4)²+(y+4)²=36 or x²-8x+8y+y²=4.
