Percent means parts out of 100
18%=18/100=1.8/10=0.18

0.18<0.70

18%<0.7

0.7 is larrger because math

.7 is larger because if you move the decimal place two to the right, you would get 70% and 70% is larger than 18%.

The sides of an oblong are in the ratio of 4:3. The oblong has a length of 12 cm and is increased by a scale factor of 2.5. What

Aleksandr [31]

Answer:

If the scale factor is increased in 2.5, the increased width will be:

<u>22.5 cm</u>

Step-by-step explanation:

Remember that an oblong is longer than it is wide, by this reason, the ratio of 4:3 could mean, if we give a number, by each 4 cm in the length, there is 3 cm in the width, in this form, if the oblong has a length of 12 cm, the width is:

4 cm ⇒ 3 cm
12 cm ⇒ x

So:

$x=\frac{12 *3}{4}$
$x=\frac{36}{4}$
$x=9$

Then, the original width is 9 cm, as the scale factor must be increased 2.5, we can multiply the found width to obtain the increased width:

Increased width = 9 cm * 2.5
<u>Increased width = 22.5 cm</u>

As you can see, <u><em>the increased widt will be 22.5 cm</em></u>.

A competitive diver dives from a 33-foot high diving board. The height of the diver in feet after 't' seconds is given by u(t) =

ludmilkaskok [199]

Answer:

$t = 0.375s$

Step-by-step explanation:

Given

$h(t) = -16t^2 + 4t + 33$ --- driver 1

$Rate = 2ft/s$ -- driver 2

$height = 33ft$

Required

The time they passed each other

First, we determine the function of driver 2.

We have that:

$Rate = 2ft/s$ and $height = 33ft$

So, the function is:

$h_2(t) = Height - Rate * t$

$h_2(t) = 33 - 2t$

The time they drive pass each other is calculated as:

$h(t) = h_2(t)$

$-16t^2 + 4t + 33= 33 - 2t$

Collect like terms

$-16t^2 + 4t + 2t= 33 - 33$

$-16t^2 + 6t= 0$

Divide through by 2t

$-8t + 3= 0$

Solve for -8t

$-8t = -3$

Solve for t

$t = \frac{-3}{-8}$

$t = 0.375s$
