What is the area of this figure? 28 yd² 40 yd² 52 yd² 64 yd²

Lubov Fominskaja [6]

Answer: A= s^2 <- for a square

A= 1/2*b*h <- for a triangle

A= 4^2= 16

A= 1/2*8*6 (The whole height is 8 yd)

A= 1/2*48

A= 24

24+16= 40 yd^2

"B" is the answer.

I hope this helps!

Step-by-step explanation: A= s^2 <- for a square

A= 1/2*b*h <- for a triangle

A= 4^2= 16

A= 1/2*8*6 (The whole height is 8 yd)

A= 1/2*48

A= 24

24+16= 40 yd^2

Beaker A contains 1 liter which is 30 percent oil and the rest is vinegar, thoroughly mixed up. Beaker B contains 2 liters which

alekssr [168]

Answer:

1.25 liters of oil

Step-by-step explanation:

Volume in Beaker A = 1 L

Volume of Oil in Beaker A = 1*0.3 = 0.3 L

Volume of Vinegar in Beaker A = 1*0.7 = 0.7 L

Volume in Beaker B = 2 L

Volume of Oil in Beaker B = 2*0.4 = 0.8 L

Volume of Vinegar in Beaker B = 1*0.6 = 1.2 L

If half of the contents of B are poured into A and assuming a homogeneous mixture, the new volumes of oil (Voa) and vinegar (Vva) in beaker A are:

$V_{oa} = 0.3+\frac{0.8}{2} \\V_{oa} = 0.7 \\V_{va} = 0.7+\frac{1.2}{2} \\V_{va} = 1.3$

The amount of oil needed to be added to beaker A in order to produce a mixture which is 60 percent oil (Vomix) is given by:

$0.6*V_{total} = V_{oa} +V_{omix}\\0.6*(V_{va}+V_{oa} +V_{omix}) = V_{oa} +V_{omix}\\0.6*(1.3+0.7+V_{omix})=0.7+V_{omix}\\V_{omix}=\frac{0.5}{0.4} \\V_{omix}=1.25 \ L$

1.25 liters of oil are needed.

If (3 , K) and (2, 4k) are two points on a graph of a line and k is not equal to 0, what is the slope of the line?

agasfer [191]

I honestly don’t know, Try to do Y2-Y1 and X2-X1 to get your answer.
