A recipe says it produces the best sweet tea. In addition to using tea bags, the recipe calls for 1/2 cup of sugar for every 1 a
ArbitrLikvidat [17]

Answer:

y=3x

Step-by-step explanation:

In this case, the ratio between sugar and water is 0.5 : 1.5 or 1 : 3.

That means that you need three cups of water for every cup of sugar.

In order to put this into an equation, the slope would be 3/1 or simply 3, and the y-intercept is 0. Even if you used the 0.5 : 1.5 ratio, the slope would be the same since 1.5 / 0.5 = 3.

A circular path 4 feet wide has an inner diameter of 550 feet. How much farther is it around the outer edge of the path than aro
Softa [21]

Answer:

L_c=25.12ft

Step-by-step explanation:

From the question we are told that

Width of circular path w_c=4ft

Inner Diameter d_i_n=550ft

Outer diameter d_{out}= 550 +2*4  (inner diameter +  2 circular path width)

d_{out}= 550 +8\\d_{out}= 558ft

Generally the equation for inner circumference of the circle C_1 is mathematically given by

C_1=\pi d_{in}

C_1=3.14*550

C_1=1727ft

Generally the equation for outer circumference of the circle C_2 is mathematically given by

C_2=\pi d_{out}

C_2=3.14*558

C_2=1752.12ft

Generally the difference in length of the two circumference L_c is mathematically given by

L_c=C_2-C_1

L_c=1752.12-1727

L_c=25.12ft
