AfilCa [17]
Log₄20-log₄ 45+log₄144=
log₄(20/45)+log₄144=                        (log_a b- log_a c=log_a  (b/c) )
log₄[(20*144)/45]=                             (log_a b +log_a c=log_a (b*c) )
log₄(2880/45)=
log₄(64)=n     ⇔      4^n=64                (log_a x=n   ⇔ a^n=x)

4^n=4³      ⇒n=3                                 (64=4*4*4=4³)

Answer: log₄20-log₄ 45+log₄144=3

The sales tax for an item was $24.50 and it cost $490 before tax.
Ymorist [56]

The sales tax rate is 5%.

Step-by-step explanation:

Given,

Sales tax for an item = $24.50

Cost of item before tax = $490

Sales tax rate = \frac{Sales\ tax}{Cost\ of\ item}*100\\

Sales\ tax\ rate=\frac{24.50}{490}*100\\\\Sales\ tax\ rate=\frac{2450}{490}\\\\Sales\ tax\ rate=5\%

The sales tax rate is 5%.

The last one need the right answer please
Llana [10]

Answer:

Part 1) The unit rate is 16\frac{dollars}{ounce}

Part 2) The unit rate is \frac{1}{4}\frac{dollars}{ounce}

Part 3) The unit rate is \frac{1}{4}\frac{dollars}{ounce}

Part 4) The unit rate is 4\frac{dollars}{ounce}

see the attached figure

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{d2-d1}{n2-n1}

where

d ----> number of dollars (dependent variable or output value)

n ---> number of ounces (independent variable or input value)

Remember that the slope of the linear equation is the same that the unit rate

<u><em>Verify each case</em></u>

1) we have

d=16n

This is a proportional relationship between the variables d and n

The slope is

m=16\frac{dollars}{ounce}

therefore

The unit rate is 16\frac{dollars}{ounce}

2) we have

<em>First table</em>

take two points from the table

(4,1) and (16,4)

substitute in the formula of slope

m=\frac{d2-d1}{n2-n1}

m=\frac{4-1}{16-4}

m=\frac{3}{12}\frac{dollars}{ounce}

simplify

m=\frac{1}{4}\frac{dollars}{ounce}

therefore

The unit rate is \frac{1}{4}\frac{dollars}{ounce}

3) we have

n=4d

This is a proportional relationship between the variables d and n

isolate the variable d

d=\frac{1}{4}n

The slope is

m=\frac{1}{4}\frac{dollars}{ounce}

therefore

The unit rate is \frac{1}{4}\frac{dollars}{ounce}

4) we have

<em>Second table</em>

take two points from the table

(1,4) and (2,8)

substitute in the formula of slope

m=\frac{d2-d1}{n2-n1}

m=\frac{8-4}{2-1}

m=4\frac{dollars}{ounce}

therefore

The unit rate is 4\frac{dollars}{ounce}
