The ratio of dye to pounds of clothing is constant. A worker develops the chart below to show the amount of dye needed for diffe

Kruka [31]

Answer: 28 pounds of clothing

Step-by-step explanation:

Here the given table,

Weight of clothing : 22 28 34 36

Cups of dye : 5.5 6.5 8.5 9

Since, the ratio of 22 pounds of clothing and 5.5 cups of dye

= $\frac{22}{5.5} = 4$

The ratio of 28 pounds of clothing and 6.5 cups of dye

= $\frac{28}{6.5} = 4.30769231\approx 4.31$

The ratio of 34 pounds of clothing and 8.5 cups of dye

= $\frac{34}{8.5} = 4$

The ratio of 36 pounds of clothing and 9 cups of dye

= $\frac{36}{9} = 4$

Thus, by the above explanation, we can say that the ratio of the 28 pounds of the cloth and the 6.5 cups is different from other ratios.

Use the properties of logarithms to expand the expression as a sum or difference, and/or constant multiple of logarithms. (Assum

Alecsey [184]

Answer:

$\log_5(9)+\frac{1}{2}\log_5(x)-3\log_5(y)$

Step-by-step explanation:

$\log_5(\frac{9\sqrt{x}}{y^3})$

First rule I'm going to use is the quotient rule:

$\log_b(\frac{m}{n})=\log_b(m)-\log_b(n)$

$\log_5(9\sqrt{x})-\log_5(y^3)$

Secondly, I'm going to rewrite the radical.

$\sqrt{x}=x^\frac{1}{2}$

$\log_5(9x^\frac{1}{2})-\log_5(y^3)$

Third, I'm going to use the product rule on the first term:

$\log_b(mn)=\log_b(m)+\log_b(n)$

$\log_5(9)+\log_5(x^\frac{1}{2})-\log_5(y^3)$

Fourth, I'm going to use power rule for both of the last two terms:

$\log_b(m^r)=r\log_b(m)$

$\log_5(9)+\frac{1}{2}\log_5(x)-3\log_5(y)$

Use the rule (x,y) (3x,2y) to find the image for the preimage defined by the given points.

Elina [12.6K]

Answer: The points of the images are (9,10), (15,6), (6,4) and the image is not a rigid motion because the shape changes in side.

Step-by-step explanation:

Since it gives you the scale factor then find they coordinates by multiplying the coordinates by the scare factor.

A(3,5) → (3*3,5*2) → (9,10)

B( 5,3) → (5*3, 3*2) → (15,6)

C ( 2,3)→ (2*3, 2*2)→ ( 6,4)
