Answer:

5.848 in

Step-by-step explanation:

Divide the piece of cardboard into nine equal squares of side z.

The centre square is the base of the cube.

When you cut out the corner squares and fold up the sides, you will have a cube with edge length z.

The cube must have a volume of 200 in³.

V = z³

200 = z³

$z = \sqrt[3]{200}$

$z = \sqrt[3]{8\times25}$

$z = 2\sqrt[3]{25}$

z = 2 × 2.924

z = 5.848 in

The edge length of the cube is 5.848 in.

juan bought supplies for his new gecko. He bought four plants for p dollars each. He also bought a 10-gallon tank for $10 and a

murzikaleks [220]

Cost of 1 plant = $ p

Cost of 4 plants = $(4p)

Cost of a 10-gallon tank = $10

Cost of a water dish = $3

Total cost = 4p + 10 + 3 = 4p + 13

A rectangle in the xy-coordinate plane is formed by the points (1,−4), (1,6), (3,−4), and (3,6). What is the perimeter of this r

Airida [17]

Answer:

Perimeter of the rectangle= $20+2\sqrt{104}$

Step-by-step explanation:

The perimeter of the rectangle with the given coordinates is the sum of its all four sides:

Let the points be A(1,-4), B(1,6), C(3,-4) and D(3,6)

Finding the sides of the rectangle using the Distance formula:

AB=

$\sqrt{(1-1)^2+(6-(-4))^2} \\\\=\sqrt{0+10^2} \\\\=\sqrt{100}\\\\ =10$

$=\sqrt{(3-1)^2+(-4-6)^2} \\\\=\sqrt{2^2+(-10)^2}\\\\ =\sqrt{4+100} \\\\=\sqrt{104}$

CD=

$\sqrt{(3-3)^2+(6-(-4))^2} \\\\=\sqrt{0+10^2} \\\\=\sqrt{100} \\\\=10$

AD=

$\sqrt{(3-1)^2+(6-(-4))^2} \\\\=\sqrt{2^2+10^2} \\\\=\sqrt{4+100}\\\\ =\sqrt{104}$

Perimeter of the rectangle=AB+BC+CD+AD

= $10+\sqrt{104}+ 10+\sqrt{104}$

Perimeter of the rectangle= $20+2\sqrt{104}$

I NEED HELP BEFORE 10:00 A.M!

Answer:

A. = 20 in²

B. = 45 ft²

C. = 29.5 ft²

D. = 36 ft²

E. = 28 ft²

Step-by-step explanation:

A. Formula = A = (h_b b)/2 = base 10 ft height_b= 4ft = 20 ft²

B. We have a rectagnle and a triangle: Formula: A = lw

= A = 30 ft² and now the triangle with the same formula as above: A = 15 ft²

30 ft²+15 ft² = 45 ft²

C. we have 2 rectagnle and a triangle: First the small recangle: A= lw = A = 1ft x 2ft = 2ft²

Second rectangle: 5 ft x 4 ft = 20 ft²

Right angeled triangle Formula: (ab)/2 = 3 ft x 5 ft = 7.5 ft²

Add it all together: 2ft²+20ft²+7.5ft² = 29.5 ft²

D. is a rectangle and a triangle: 8 ft x 3 ft = 24ft²

the triangle 8 ft x 2ft = 12 ft²; add 24 ft²+12 ft² = 36ft²

E. is a right-angled triangle (see fromula above) = (14 ft x 4 ft)/2 = 28ft²
