Given :

Lin has a pet German shepherd that weighs 38 when measured in one unit and 84 when measured in a different unit.

To Find :

Which measurement is in pounds, and which is in kilograms.

Solution :

We know, mass in kg and pounds are related as :

m_P = 2.2m_{kg}

Putting, m_{kg}=38 and m_P=84 , we get :

LHS = 84

RHS = 2.2 × 38 = 83.6 ≈ 84

Since, LHS = RHS .

Therefore, 38 units is Kg and 84 units in Pounds.

Hence, this is the required solution.

This graph represents −x−2y=−4 .
alekssr [168]

Answer:

B

Step-by-step explanation:

We have the equation -x-2y=-4 and we want to find which ordered pair is in the solution -x-2y\leq -4

First, let's convert the inequality to slope-intercept form. So, we have:

-x-2y\leq-4

Add x to both sides:

-2y\leq x-4

Divide both sides by -2. Since we're dividing by a negative, we will flip the sign:

y\geq- \frac{1}{2}x+2

Therefore, our original inequality will be the same as above.

Notice that our y is <em>greater than</em> our equation.

Therefore, the shaded area will lie <em>above</em> our line.

So, any point that falls within the region above our line (in the graph) and on the line is a solution to our inequality.

(-4, 1) is below our line, so it's not a solution.

(-1, 4) is above our line. So, (-1, 4) is our answer.

(-4, -1) is again below our line. So, it's not a solution.

Finally, (4, -1) is also below our line, so it's not a solution.

Therefore, our final solution is B: (-1, 4).

Let's check this. Substitute -1 for x and 4 for y. This yields:

-(-1)-2(4)\stackrel{?}{\leq}4

Multiply:

1-8\stackrel{?}{\leq}{4}

Subtract:

-7\stackrel{\checkmark}{\leq}4

So, (-1, 4) is indeed our solution.

And we're done!

A trader paid 1500 for 6 drinking cups. one of the cups got broken. he sold the remaining five, making a profit of 10percent cal
tankabanditka [31]

Answer:

Cost price of each cup = 1500/6 = 250

Selling price of each cup = 1650/5 = 330

Step-by-step explanation:

Cost price of cups = 1500

Profit = 10%

Selling price of cups = ?

Profit and loss percentage are calculated based on cost price and the formula to calculate profit is mentioned as under:

Profit percentage (%) = Profit x 100/Cost price

10 = Profit x 100/1500

⇒ Profit = 10 x 1500/100

⇒ Profit = 150

The formula for finding selling price is mentioned as under:

Selling Price = Profit + Cost Price.

Selling Price = 150 + 1500

⇒ Selling Price = 1650.

Since one of the six cups was broken that means the seller earned profit based on only 5 cups, it implies that selling price of each cup will be 1650/5 = 330.
