Mary wants to put 1/10 of a kilogram of bird seed in each of the bird cages in her pet shop. She has 3/10 of a kilogram of bird

alex41 [277]

Answer:

A) 3

Step-by-step explanation:

If you simply look at the given numbers, it should be pretty clear that 3 tenths is 3 times 1 tenth.

When Mary puts 1/10 kg in each cage, she can do that for 3 cages with 3/10 kg of bird seed.

If you let c represent the number of cages, then the amount of bird seed used will be (1/10)c. This will be equal to the amount available when we use it all for filling cages:

(1/10)c = (3/10)

Multiply both sides of the equation by 10:

c = 3

Mary can fill 3 cages with available seed.

The length of a picture is 15.75 inches shorter than twice the width. If the perimeter of the picture is 106.5 inches, find its

Vladimir79 [104]

Answer:

Length = 45.37 in

Width = 30.56 in

Step-by-step explanation:

Let the width of the picture be 'w' inches.

Given:

Perimeter of the picture is, $P=106.5\ in$

Length is 15.75 inches shorter than twice the width. So, length is:

$l=2w-15.75$

Now, we know that the perimeter of a rectangular shape is given as the sum of all of its side. So, the picture is also of rectangular shape and hence the perimeter is given as:

$P=2l+2w$

Plug in the values of 'l' and 'P' and solve for 'w'. This gives,

$106.5=2w-15.75+2w\\106.5=4w-15.75\\106.5+15.75=4w\\4w=122.25\\w=\frac{122.25}{4}=30.56\ in$

Therefore, the width of the rectangular picture is 30.56 inches.

Length of the picture is, $l=2(30.56)-15.75=61.12-15.75=45.37\ in$

So, length of the picture is 45.37 inches and width is 30.56 inches.

A particle is moving horizontally along the x-axis. Its position (in ft) is: s(t)=t^3-18t^2+33t+14 where t is in sec.

UNO [17]

Answer:

t=11 sec

Step-by-step explanation:

The position of the particle moving along the x-axis is given by:

$s(t) = {t}^{3} - 18 {t}^{2} + 33t + 14$

The velocity is given by:

$s'(t) = 3 {t}^{2} - 36{t} + 33$

If s'(t)>0 then the particle is moving right.

$3 {t}^{2} - 36{t} + 33 \: > \: 0 \\ {t}^{2} - 12{t} + 11\: > \: 0$

$\implies \: t \: < \: 1 \: or \: t \: > \: 11$

This means that the particle is moving left when

$1 \: < \: t \: < \: 11$

The particle changes direction at time t=1 or t=11

Find the product. x^5 x^4 x^3

Brut [27]

If you would like to solve x^5 * x^4 * x^3, you can do this using the following steps:

<span>x^5 * x^4 * x^3 = x^(5 + 4 + 3) = x^12
</span>
The correct result would be x^12.
