lianna [129]

Answer:

The 10% off sale will save Melissa <u>$10.49</u>.

Step-by-step explanation:

Given:

The listed price of the camera is $195.99.

The camera is no sale for 10% off and Melissa has a coupon for 5% off the sales tax is 7%.

Now, to find the money Melissa will save of the 10% off sale.

So, to get the price of camera of the 5% off sale:

$(195.99-5\%\ of\ 195.99)$

$=(195.99-\frac{5}{100}\times 195.99)$

$=(195.99-9.80)$

$=186.19$

Now, adding the sales tax:

$186.19+7\%\ of\ 186.19$

$=186.19+\frac{7}{100} \times 186.19$

$=186.19+13.03$

$=199.22$

Thus, the price is $199.22.

Now, to get the price of 10% off sale:

$195.99-10\%\ of\ 195.99$

$=195.99-\frac{10}{100} \times 195.99$

$=176.39$

So, adding sales tax:

$176.39+7\%\ of\ 176.39$

$=176.39+\frac{7}{100} \times 176.39$

$=188.73$

Hence, the price is $188.73.

Now, to get the money 10% off sale will save Melissa:

$199.22-188.73$

$=10.49$

Therefore, the 10% off sale will save Melissa $10.49.

Answer:

I answered the questions but that formatting is very confusing and discourages anyone for trying to answer.

The last question is confusing. If I got it wrong, tell me. I will try to answer in the comment section then.

Step-by-step explanation:

Kayson is looking at two buildings, building A and building B, at an angle of elevation of 73°. Building A is 30 feet away, and building B is 35 feet away. Which building is taller and by approximately how many feet?

$\text{tan}\theta=\frac{h_{A}}{30} \Rightarrow h_{A}=\text{tan}73\º \cdot 30 \Rightarrow h_{A}\approx 98.12 \text{ feet}$

$\text{tan}\theta=\frac{h_{B}}{35} \Rightarrow h_{B}=\text{tan}73\º \cdot 35 \Rightarrow h_{B}\approx 114.47 \text{ feet}$

$\text{Difference} \approx 16.35$

Building B is around 16.35 feet taller than building A.

A Look at the figure below: an image of a right triangle is shown with an angle labeled y If sin y° = a divided by 6 and tan y° = a divided by b, what is the value of cos y°?

$\text{sin}(y)=\frac{a}{6}$

$\text{tan}(y)=\frac{a}{b}$

a is the opposite side; 6 is the hypotenuse; b is the adjacent side.

Therefore,

$\text{cos}(y)=\frac{b}{6}$

If sin f° = eight ninths and the measure of segment YW is 24 units, what is the measure of segment YX? triangle XYW in which angle W is a right angle, angle X measure f degrees, and angle Y measures d degrees.

This seems a bit confusing. The angles don't match. We have $90\º+62\º +21\º \approx 173\º$
