garri49 [273]

Answer: 14.60

Step-by-step explanation:

we have

14 3/5

This is a mixed number

we know that

A mixed number is a combination of a whole number and a fraction.

14 3/5 is equal to

14+3/5

where

14 is the whole number

3/5 is the fraction

3/5 = 0.60

14 + 3/5 = 14 + 0.60

therefore

= 14.60

the answer is

14.60

Julia is allowed to watch no more than 5 hours of television a week. So far this week, she has watched 1.5 hours. Write and solv

Leona [35]

The inequality is used to solve how many hours of television Julia can still watch this week is $x + 1.5 \leq 5$

The remaining hours of TV Julia can watch this week can be expressed is 3.5 hours

<h3><u>Solution:</u></h3>

Given that Julia is allowed to watch no more than 5 hours of television a week

So far this week, she has watched 1.5 hours

To find: number of hours Julia can still watch this week

<em>Let "x" be the number of hours Julia can still watch television this week</em>

"no more than 5" means less than or equal to 5 ( ≤ 5 )

Juila has already watched 1.5 hours. So we can add 1.5 hours and number of hours Julia can still watch television this week which is less than or equal to 5 hours

number of hours Julia can still watch television this week + already watched ≤ Total hours Juila can watch

$x + 1.5 \leq5$

Thus the above inequality is used to solve how many hours of television Julia can still watch this week.

Solving the inequality,

$x + 1.5 \leq5\\\\x \leq 5 - 1.5\\\\x \leq 3.5$

Thus Julia still can watch Television for 3.5 hours

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2. How

kozerog [31]

Answer:

it will take 5.5 seconds to hit the ground

Step-by-step explanation:

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by $h = 88t - 16t ^2$

When the projectile hits the ground then the height becomes 0

$h = 88t - 16t ^2$

$0 = 88t - 16t ^2$

GCF is -8t

$0 = 8t(11 - 2t)$

now set each factor =0 and solve for t

$8t=0, t=0$

$11-2t=0, t=\frac{11}{2}$

So it will take 5.5 seconds to hit the ground
