Answer:

Sales tax = 7%.

Step-by-step explanation:

Let x be the percent of sales tax.

We have been given that Lisa buys a television for $4185. The sales tax is $292.95.

We need to figure out x such that x percent of 4185 equals to 292.95. Let us represent this information in an equation.

\frac{x}{100}*4185=292.95

Let us multiply both sides of equation by 100.

100*\frac{x}{100}*4185=100*292.95

x*4185=29295

x=\frac{29295}{4185}

x=7

Therefore, sales tax is 7%.

Let us cross check our answer by calculating 7% of 4185.

7\%\text{ of } 4185=\frac{7}{100}\times 4185

7\%\text{ of } 4185=0.07\times 4185

7\%\text{ of } 4185=292.95

We can see that 7% of 4185 is 292.95. Hence, sales tax is 7%.

How do you simplify that question? For algebra 1.
motikmotik
\left( \sqrt{x^{-3}} \right)^5 =  \left( \sqrt{ \frac{1}{x^3} } \right)^5= \frac{1}{ (\sqrt{x^3})^5 } = \frac{1}{ \sqrt{x^{15}} } = \frac{1}{x^7 \sqrt{x} }


<span>Explanation for the last step:</span>
\sqrt{x^{15}}= \sqrt{x^{14}*x}= \sqrt{x^{14}}* \sqrt{x} =x^{ \frac{14}{2} }* \sqrt{x} =x^7 \sqrt{x}

a test battery contains the following three items: distance runs, skinfolds, and trunk extension. what does that test battery me
Katen [24]

A test battery contains the following three items: distance runs, skinfolds, and trunk extension.  The test battery measure is health-related physical fitness.

Traditionally, the phrase "battery" turned into used to describe a "series of similar items grouped collectively to perform a feature," as in a battery of artillery. In 1749, Benjamin Franklin first used the term to explain a chain of capacitors he had related together for his strength experiments.

Batteries and comparable devices receive, save, and launch power on call. Batteries use chemistry, in the form of chemical capability, to save electricity, similar to many different normal electricity sources. for example, logs keep electricity in their chemical bonds till burning converts the electricity to heat.

The average alkaline AAA, AA, C, D, 9-volt or button-cellular battery is made of metal and a combination of zinc/manganese/potassium/graphite, with the ultimate balance, made up of paper and plastic. Being non-poisonous substances, all of those battery “substances” are effortlessly recyclable.
