A girl studied for 5 2/3 hours daily. She devotes 2 4/2 hours of her time for science and mathematics. How much time does she devote for other subjects?
Given :
Number of hours studied daily , [tex]T=5\dfrac{2}{3}[/tex] .
Time given for science and mathematics is , [tex]t=2\dfrac{4}{2}[/tex] .
To Find :
How much time does she devote for other subjects .
Solution :
Let , time devote for other student is x .
So , Time left for other subject = Total time - Time taken by science and mathematics .
[tex]x=T-t\\\\x=5\dfrac{2}{3}-2\dfrac{4}{2}\\\\x=\dfrac{(5\times 3)+2}{3}- \dfrac{(2\times 2 )+4}{2}\\\\x=\dfrac{17}{3}-4\\\\x=\dfrac{17-(4\times 3)}{3}\\\\x=\dfrac{5}{3}=1\dfrac{2}{3}[/tex]
Therefore , time devote for other subject is [tex]1\dfrac{2}{3}[/tex] hours .
Hence , this is the required solution .

for rectangular prism rewrite the formula to find the length in terms of area, width, and height
Pls help T-T. Im offering 38 points for this question
The formula to find the volume is [ v = whl ]
v = volume
w = width
h = height
l = length
We need to solve for l.
v = wdl
Divide wd to both sides
v/wd = l

15 less than a number S is three more than 9 times a number T. Solve for S
Answer:
s = 9t + 18
Explanation:
Set up your equation
s - 15 = 9t + 3
Now get s by itself by adding 15 to both sides
s + 0 = 9t + 3 + 15
s = 9t + 18
If you know the value of t, plug that into the equation to solve further.

Samantha claims 3/5 is an integer is she correct?
Answer:
no
Step-by-step explanation:
because integers are positive and negative numbers
Answer:
She is not correct
Step-by-step explanation:
This is the answer because:
1) We know that an integer is either a negative or positive number which has no fractional components/ no relation to fractions.
2) This means that an integer should not be expressed in the x/y form, also known as the fraction form.
3) Integers should always be a whole number that is negative or positive. An integer should never be a "part" of a number.
Therefore, 3/5 in not an integer

Jesse runs a 26-mile race in 5 hours. LJ runs a 15-mile race in 2 hours. Who runs at a slower rate?
Answer: Jesse
because i guess i divided the number you could do it however 15 divided by 2 = 7.5 and 26 divided by 5 = 5.2
Answer:
Jesse is the slower rate.
Step-by-step explanation:
The slower rate is going to be determined by the distance divided by the time.
Jesse: 26 / 5 = 5.2 miles / hour
LJ: 15 / 2 = 7.5 miles / hour
Jesse is the slower rate.
What value of x is in the solution set of 3(x – 4) > 5x + 2?
Choices
-10
-5
5
10
We have to simplify and get the value of x from this inequality given:
Given inequality,
[tex]3(x - 4) > 5x + 2[/tex]
Now let's simplify by using distributive property,
[tex]3x - 12 > 5x + 2[/tex]
We need to find x, so let's isolate x to the letter side of the inequality for calculation at ease.
[tex]3x - 12 - 5x - 2 > 0[/tex]
[tex] - 2x - 14 > 0[/tex]
Now, dividing -2 from both sides.
Note : As we are dividing a negative number from both sides, the sign of the inequality will be reversed.
[tex] \dfrac{ - 2x - 14}{ - 2} > \dfrac{0}{ - 2} [/tex]
[tex]x + 7 < 0[/tex]
Now subtracting -7 from both sides,
[tex]x + 7 - 7 < 0 - 7[/tex]
[tex]x < - 7[/tex]

A golf ball is hit with a club from the ground on a flat surface. The height of the ball, h(t), in feet, t seconds, after it was hit can be modeled by the function h(t)=40t-16t2
Answer:
Step-by-step explanation:
The question is incomplete. Find the complete question a=below;
A golf ball is hit with a club from the ground on a flat surface. The height of the ball, h(t), in feet, t seconds, after it was hit can be modeled by the function h(t)=40t-16t2. After how many seconds does the golf ball strike the ground?
The ball strikes the ground when the height h(t) = 0. To get the time wen the golf ball strikes the ground, we will substiute h = 0 into the modeled equation and calculate t as shown;
h(t)=40t-16t2
0 h(t)=40t-16t2
40t-16t² = 0
add 16t² to both side
40t-16t²+16t² = 0+16t²
40t = 16t²
40 = 16t
divide both sides by 16
t = 40/16.
t = 2.5secs
Hence the golf ball hit the ground after 2.5secs
Answer:
when the ball is hit as 0 second it has a height of 0 feet (because it hasnt done anything yet). The ball's height increases until it reaches its maximum height of 40 feet after 1.25 seconds (40t= 2.5/2). The balls height then decreases until it reaches 2.5 seconds after it was hit.
A gamestop you can buy a xbox one foe 150.00 and each game to go with it would cost 24.00 or you can buy a playstation 4 for 180.00 abd esch game for 20.00
Answer:
Let's write two linear equations:
For the Xbox, we have:
Price per console (you pay it only once) = $150.
Price per game = $24
Then, the total price if you buy x games, you have:
P1(x) = $150 + $24*x
For the Playstation we have:
Price per console (again yo pay it only once) = $180
Price per game = $20
So if you buy x games, the total price is:
P2(x) = $180 + $20*x.
Now, we can find the number x such that both prices are equal
P1(x) = P2(x)
$150 + $24*x = $180 + $20*x.
let's solve this for x.
$24*x - $20*x = $180 - $150
$4*x = $30
x = $30/$4 = 7.5
What does this mean?
If you buy less than 7.5 games (7 or less) then the Xbox will be cheaper, because the y-intercept is smaller.
If you buy more than 7.5 games (8 or more) then the Playstation will be cheaper, because the price per game is smaller.
