The length of a rectangular swimming pool is twice as long as its width. If the perimeter of the pool is

Nitella [24]

The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:

$p=w+w+l+l$

Since the length is twice the width, we have $l=2w$ , and the formula for the perimeter becomes

$p=w+w+2w+2w=6w$

So, we have

$6w=120 \iff w=\dfrac{120}{6}=20$

If i purchase a product for $79.99 and two accessories for 9.99 and 7.00 how much will i owe after taxes applies 8.75%

ehidna [41]

Answer:

The price will be $105.47

Step-by-step explanation:

Given that i purchase a product for $79.99 and two accessories for $9.99 and $7.00. we have to find how much will i owe after taxes applies 8.75%

Now, the cost price of the product and the two accessories will be

$79.99+$9.99+$7.00

= $96.98

Now, also the tax applies at the rate 8.75%

∴ $Tax=8.75\%\thinspace of\thinspace96.98$

= $8.48575=8.49(approx)$

Hence, the price which i owe after taxes will be $96.98+$8.49=$105.47

Horatio wrote the multiplication facts for 8. which digit will not be in the ones place of the products?

dangina [55]

Answer:

Odd digits like 1, 3, 5, 7, and 9will not be at ones place of the products.

Step-by-step explanation:

If we look at multiplication facts of 8 we can see that,

8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96 etc

We can see that at the ones place, only even digits show up, like

0, 2, 4, 6, 8

But there is no odd digit at ones place.

So if Horation wrote the multiplication facts for 8, none of the odd digits will be there at ones place. Those digits include, 1, 3, 5, 7 and 9.

Marianna [84]

Answer: $1809.792\ m^3$

Step-by-step explanation:

Given

The diameter of the cylinder is $d=12\ cm$

height of the cylinder is $h=16\ cm$

The volume of a cylinder is given by

$V=\pi r^2h$

Insert the values

$\Rightarrow V=\pi \times 6^2\times 16\\\Rightarrow V=3.142\times 576\\\Rightarrow V=1809.792\ m^3$

The volume of the cylinder is $1809.792\ m^3$
