Answer:

1.5375

Step-by-step explanation:

Multiply without the decimal points, then put the decimal point in the final answer

1025 x 15 = 15375

....

10.25 has TWO decimal places

0.15 has TWO decimal places

Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.

So the answer is 1.5375

The length of a rectangle is five times its width. If the area of the rectangle is 320m, find the perimeter

Roman55 [17]

Answer: The perimeter is 96 m

Step-by-step explanation:

If we tag the length of the rectangle as $l$ and the width as $w$ , and if in addition we are told $l=5 w$ ,the dimensions of the rectangle are as shown in the figure.

Now, the area of a rectangle is given by:

$A=(l)(w)=320 m^{2}$

Since $l=5 w$ :

$A=(5w)(w)=320 m^{2}$

Isolating $w$ :

$5w^{2}=320 m^{2}$

$w=\sqrt{\frac{320 m^{2}}{5}}$

$w=8 m$

On the other hand, the perimeter of a triangle is given by the addition of each of its sides. Then, if the rectangle has two sides that measure $w$ and two sides that measure $5 w$ , the perimeter is:

$P=2(5)(w)+2w$

Substituting the value of $w$ in the last equation:

$P=2(5)(8 m)+2(8 m)$

Finally the perimeter is:

$P=96 m$

A plot of land is 3/8 mile by 2 1/4 miles. Spencer solves 3/8•2 1/4 to find the area of the land in square miles. Enter numbers

Marina CMI [18]

9514 1404 393

Answer:

Step-by-step explanation:

The number 2 1/4 is split into the sum 2 + 1/4, then multiplied by 3/8. This gives ...

$\displaystyle\frac{3}{8}\cdot2\frac{1}{4}=\left(\frac{3}{8}\cdot\boxed{2}\right)+\left(\frac{3}{8}\cdot\frac{1}{4}\right)\\\\=\frac{6}{8}+\frac{3}{\boxed{32}}=\frac{24}{32}+\frac{3}{32}=\frac{24+3}{32}\\\\=\frac{\boxed{27}}{32}$

Of course, fractions are multiplied in the usual way:

$\dfrac{a}{b}\cdot\dfrac{c}{d}=\dfrac{ac}{bd}$

Write an inequality to model the situation: The number n of people who attend the class was at least 8

OLEGan [10]

"at least" means less than or equal to, because it means that it could be as many as 8, but possibly less. with that in mind:

n ≤ 8 is your inequality. the number of people was less than or equal to 8
