Answer:

48%

Step-by-step explanation:

let's say the initial price of an item is $100

if you take 40% off then you pay only $60

now if you take 20% off 60 you pay $48

$48 is 48% of 100

A rectangular field has a length of 105 feet and a width of 60 feet. On a map of the field, the width was drawn as 4 inches. Wha

dedylja [7]

$\frac{4}{x} x \frac{60}{105}$

105 x 4 =60x
420 = 60x ( Divide 60 on both sides to get x by itself)
7 = x

The length should be 7 inches

Hope this helps :)

The equivalent expression to the given logarithm without tables is $\mathbf{ =log_{10} (\dfrac{3x(x^2+4)}{2})}$ . Option A is correct.

<h3>What are equivalent expressions?</h3>

Equivalent expressions are expressions that differ in appearance but when a value is being replaced for their unknown variable, gives an equivalent result.

From the given information:

$\mathbf{(log_{10}(9)+log_{10}(x) + log_{10}(x^2+4) )-log_{10} (6) }$

$\mathbf{=log_{10}(9)+log_{10}(x) + log_{10}(x^2+4) -log_{10} (6) }$

$\mathbf{=log_{10}(9x)+ log_{10}(x^2+4) -log_{10} (6) }$

$\mathbf{=log_{10}(9x(x^2+4)) -log_{10} (6) }$

Apply log rule: $\mathbf{log_a(x)-log_a(y) =log_a(\dfrac{x}{y})}$

$\mathbf{=log_{10}(9x(x^2+4)) -log_{10} (6) =log_{10} (\dfrac{9x(x^2+4)}{6})}$

$\mathbf{ =log_{10} (\dfrac{9x(x^2+4)}{6})}$

$\mathbf{ =log_{10} (\dfrac{3x(x^2+4)}{2})}$

Last month, Jim and Debbie earned $7,200. Debbie earned $1,600 more than Jim earned. How much did they each earn? Call the amoun

irina [24]

Step-by-step explanation:

Let Jim earned $ x

Therefore, Debbie earned = $(x + 1600)

According to the given information:

$x + (x + 1600) = 7200 \\ \therefore \: 2x = 7200 - 1600 \\ \therefore \: 2x =5600 \\ \\ \therefore \: x = \frac{5600}{2} \\ \\ \therefore \: x =2800 \\$

Thus, Jim`s earning = $2800

Debbie`s earning = 2800 + 1600 = $4400
