Answer:

marked price = Rs. 3900

Step-by-step explanation:

The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.

The marked price is Rs. 3900.

_____

<em>Check</em>

A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.

What is the value of R

frutty [35]

Answer:

2.45 × $10^{6}$

Step-by-step explanation:

using the rules of exponents

• $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$

• $(a^m)^{n}$ = $a^{mn}$

evaluating the numerator

(3.8 × $10^{5}$ )² = 3.8² × $(10^5)^{2}$ = 14.44 × $10^{10}$

R = $\frac{14.44.10^{10} }{5.9.10^{4} }$

= $\frac{14.44}{5.9}$ × $\frac{10^{10} }{10^{4} }$

= 2.45 × $10^{6}$ ← to 2 dec. places

The linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage. Let x represent the num

Alex777 [14]

Traci will be 360 miles in 12 hours if the linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage and the equation of the graph is linear.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have a linear equation:

y = 30x

Here, x represent the number of hours and y represent the number of miles.

When x = 12 hours then

y = 30(12) = 360 miles

If draw the graph the equation y = 30x, it will be a linear equation.

(refer attached picture)

Thus, Traci will be 360 miles in 12 hours if the linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage and the equation of the graph is linear.
