If 400ml of milk is used for 8 pancakes then how much is used for 6
Naddik [55]

To solve this equation, you will need to set up a proportion where you set two fractions equal to each other.

Let x = the unknown amount of milk

\frac{400}{8} = \frac{x}{6}

You would then crossmultiply and solve for x.

8x = 400(6)

8x = 2400

x = 2400/8

x = 300

You will need 300 mL of milk to make 6 pancakes if you previously needed 400 mL to make 8 pancakes.

boyakko [2]

Answer:

7 meters

Step-by-step explanation:

circumference of path=88m

⇒2πr=88

⇒2.

22

​  

.r=88

⇒r=14m

circumference of plot=44m

⇒2πr  

′

=44

⇒2.

​  

.r  

′

=44

⇒r

=7m

therefore width of path=r−r

Solve the system of equations algebraically: x^2 +y^2 =25, y=x^2 +3
aalyn [17]

Answer:

{ \tt{ {x}^{2} +  {y}^{2}  = 25 -  -  -  \{eqn(a) \}}} \\ { \tt{y =  {x}^{2} + 3 -  -  -  \{eqn(b) \} }}

» substitute y in eqn(a) with y in eqn(b)

{ \tt{ {x}^{2} + ( {x}^{2}  + 3) {}^{2}   = 25}}  \\ { \tt{ {x}^{2}  + ( {x}^{2}  + 6x + 9) = 25}} \\ { \tt{2 {x}^{2} + 6x + 9 = 25 }} \\ { \tt{2 {x}^{2}  + 6x - 16 = 0}} \\ { \tt{x = 1.7 \:  \: and \:  \:  - 4.7}}

» Find y in eqn(b)

{ \tt{y =  {x}^{2} + 3 }} \\ { \tt{y = 5.89 \:  \: and \:  \: 25.09}}
