Mathematics

Answer:

X = 7.2

Step-by-step explanation:

Hello

For the triangle of right side, using Pytagoras:

(2.5)^2 + b^2 = 6^2

6.25 + b^2 = 36

b^2 = 36 - 6.25

b^2 = 29.75

b = 5.45

Now we can to find X using again Pytagoras:

3^2 + (5.45)^2 = x^2

9 + 29.75 = x^2

38.75 = x^2

X = 7.2

Best regards

complete each statement with the appropriate measurement or symbol. 48 c = (fill blank) qt , 96 oz (fill blank) 5 lb , 6 yd, 1 f
DochEvi [55]

Answer:

48 cub = 12 Qt

96 Oz > 5 lb

6 yd 1 ft = 9 ft

6 1/2 lb = 104 oz

Step-by-step explanation:

Use the below key formula to convert the units.

1 cub = 4 Quart

16 ounce = 1 lb

96 ounce = 6 lb

1 yd = 3 feet

6 yd 1 ft = 6*3 + 1 = 18 + 1 = 19 feet

Hope this will help you to understand.

Thank you.

Please help me !!!!!!!!!!!!!!!!
Nutka1998 [239]

Answer: x=-10, y=13

Step-by-step explanation:

-3x+2y=56\\-5x-2y=24

+2y-2y = 0, eliminating y is much easier. So -3x-5x = -8x and 56+24 = 80

-8x=80\\x=-10

Substitute x in any equations but only 1 equation (Don't substitute in both equations.)

For me, I'd substitute x in -3x+2y=50

-3(-10)+2y=56\\30+2y=56\\2y=56-30\\2y=26\\y=13

So the answer is x = -10, y = 13

Gina has 1200 yards of fencing to enclose a rectangular area. Find the dimensions of the rectangle that maximize the enclosed ar
Alekssandra [29.7K]
We know the perimeter formula would be 1200=2x+2y. And the area will be A=x*y
We can to take the derivative of the area formula to find where it is a max but we must first substitute something in from the first formula so we only have one variable.

1200-2x=2y
600-x=y

A=(x)*(600-x)
A=600x-x^2

Now we take the derivative:
A'=600-2x (set equal to 0 and solve)
0=600-2x
2x=600
x=300 

Then when we plug this into the perimeter formula, we can solve for y
1200=2x+2y
1200=2(300)+2y
1200=600+2y
600=2y
y=300

So both the length and width are 300 yards, and the area would be 90,000 square yards

Hope this helps
