a rectangular pool is 8 yards long 6 yards wide and 5 feet deep .convert the measurements of the length and width to feet​
ExtremeBDS [4]

Answer:

1 yard = 3 feet

Keeping this in mind, we need to multiply the yard lengths by 3 to convert the measurements to feet.

8 feet x 3 = 24 yards

6 feet x 3 = 18 yards

5 feet x 3 = 15 yards

So

8 ft = 24 yd

6 ft = 18 yd

5 ft = 15 yd

plz mark brainliest if this helped :)

Is this graph continuous at x=1?
drek231 [11]

Answer:

Step-by-step explanation:

By my definition, no. There's a continuity up to and including just before 1 approaching from the left, and there's a continuity just after 1 going to the right. But 1 itself has a special definition h(x) = 4 when x = 1 and that makes it discontinuous.

If $1000 is divided among the three people In the ratio 2:3:5,find the share of each​
d1i1m1o1n [39]

Answer:

$200, $300, $500

Step-by-step explanation:

Given data

Total Amount= $1000

Ratio=  2:3:5

The combined ratio is = 10

Let us apply the part to all method to find the individual amount

The first person will take

10/1000= 2/x

1/100=2/x

cross multiply

x= 200

The second person will take

10/1000= 3/x

1/100=3/x

cross multiply

x= 300

The third person will take

10/1000= 5/x

1/100=5/x

cross multiply

x= 500

Can you please help me!!
STALIN [3.7K]
Answer:
1. -8,
2. 58
3. 0
4.
5. -14/8 or -1.75


Explanation:
1. You just plug in 8 for x into the g(x) equation
So, -(8)^2+7(8)= -8

2. You do the same thing you did for number one.
Plug in 13 for the h(x) equation
|2-4(13)|= 50
Then plug in -1 for the f(x) equation
-(-1)^2+7(-1)= -8
You then do as it says- subtract h(x) from f(x)
Which is 50-(-8) and you get 58.
(That subtraction sign turns into addition/ 2 negatives make a positive)

3. Same thing again.
Plug in what they gave you (3y-1) for X
8(3y-1)-9
You get 24y-17
You then subtract off the -17 and get 24y=17
Divide the 24 off and get y=17/24
Plug the Y back into the equation
8(3(17/24)-1)-9 and you get 0

*Im not a hundred percent sure I did this one right*

4. This is the same as number 3. Didn’t have time to solve this, but it’s the same steps as number 3 :)

5. This time they didn’t give you x so you set it up differently
Now you set the f(x) equation equal to -23
8x-9=-23
Add off the to the 23 to isolate the variable
8x= -14
Divide off the 8
X= -14/8 or -1.75
