Answer:

Total distance Rory drive = 300 +142 = 442 miles

and total distance her  cousin drive = 142 miles.

Step-by-step explanation:

Total distance traveled by Rory and her cousins = 584 miles

Distance drive by Rory herself first day = 300 miles

Distance left to travel = total distance - distance drive by Rory

                                     = ( 584-300 ) miles

                                     = 284 miles.

According to the question, The second day, Rory and her cousin will share driving equally.

Let the distance traveled by cousin is S miles, then, Rory also drive S miles.

⇒  S + S = 284

⇒ 2S = 284

⇒ S = 142

So they will divide the remaining distance of 284 miles among them equally that is they both drive 142 miles.

Total distance Rory drive = 300 +142 = 442 miles

and total distance her  cousin drive = 142 miles.

Bobby bought two shares of stock, which he sold for $96 each. If he had a profit of 20 percent on the sale of one of the shares
pashok25 [27]

Answer:

The correct option is c) a loss of $8.

Step-by-step explanation:

Consider the provided information.

If the selling price of two item is same and one item sold at a profit of x % and other at a loss of x % in that case total sale result loss:

To calculate the loss use the formula: Loss\ \%=(\frac{x}{10})^2\ \%

It is given that he had a profit of 20 percent on the sale of one of the shares but a loss of 20 percent on the sale of the other share, where the selling price is $96 each.

That means the total sale result will be a loss.

Now use the above formula by substitute x=20.

Loss\ \%=(\frac{20}{10})^2\ \%\\\\Loss\ \%=4\ \%

It is given that the sales price is $96 of each that means total sales price is:

$96+$96=$192

Let the cost price of the shares were x.

According to question: x-4% of x = 192

x-\frac{4}{100}\times x = 192\\\\x-0.04x = 192\\\\0.96x = 192\\x = 200

Hence, the cost price of the shares was 200.

Loss = Cost price -Sales price

Loss = $200 - $192

Loss = $8

Hence, the correct option is c) a loss of $8.

Find the missing measures for the rectangle. l = _?_ w = 4.2 m A = 37.8 m2 P = _?_ A) 9 m; 26.4 m B) 14.7 m; 61.74 m C) 9 m; 13.
egoroff_w [7]

Answer:

The correct answer is A.

Step-by-step explanation:

The area of a rectangle can be calculated using the following formula:

Ar=W . I

If we know that the area measures 37.8 m^{2} and one side of the figure measures 4.2 m, we can say that:

37.8m^{2}=4.2m. I

We isolate the side we don't know:

\frac{37.8m^{2}}{4.2m} = I\\9 m = I

So I = 9 m

To know the perimter of a rectangle, we use the following formula:

P= I. 2 + W . 2

P= 9m. 2 + 4.2m. 2

P= 26.4 m

A square has side length of 9 in. If the area is doubled, what happens to the side length?
Alika [10]

Answer:

The side length is multiplied by \sqrt{2}

Step-by-step explanation:

we know that

The area of the original square is equal to

A=9^{2}=81\ in^{2}

If the area is doubled

then

The area of the larger square is

A1=(2)81=162\ in^{2}

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the larger square

y ---> the area of the original square

so

z^{2}=\frac{x}{y}

we have

x=162\ in\^{2}

y=81\ in\^{2}

z^{2}=\frac{162}{81}

z^{2}=2

z=\sqrt{2} ------> scale factor

therefore

The side length is multiplied by \sqrt{2}
