Mary is incorrect. Perimeter is not proportional to area. An example which you can use is garden A is an 8 by 1 rectangle. The perimeter is 18 while the area is 8. Graden B is a 4 by 4 square. The perimeter is 16 (less than garden A) while the area is 16 (two times more than garden B).

Find the value of the expression below when x = 27, y = - 4 , and z = 64 . 2 * root(3, x) - 5sqrt(x) + y ^ 2 answer

Anna71 [15]

Answer:

-18

Step-by-step explanation:

x = 27, y = - 4, z = 64

<u>Expression:</u>

2∛x - 5√z + y² =
2∛27 - 5√64 + (-4)² =
2(3) - 5(8) + 16 =
6 - 40 + 16 =
-18

Y = x2+6x+8 and y = (x+2)(x+4) both define the same quadratic function. Without graphing, identify the x- and y-intercepts of th

mash [69]

Answer:

x-int:(-2,0)(-4,0) . y-int:(0,8)

Step-by-step explanation:

y = x2+6x+8 and y = (x+2)(x+4)

x-int:

x+2=0

x= -2

(-2,0)

x-int:

x+4=0

x=-4

(-4,0)

y-int: plug 0 for x

y=(0+2)(0+4)

y=8

Trey had a cylindrical can with a radius of 4 inches and a height of 12 inches that was completely full of beet juice. He poured

Slav-nsk [51]

Answer:

$8\ glasses\ of\ juice$

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4\ in$

$h=12\ in$

substitute the values

$V=\pi (4)^{2}(12)=192\pi\ in^{3}$

step 2

Find the volume of the cylindrical glasses

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=2\ in$

$h=8\ in$

substitute the values

$V=\pi (2)^{2}(8)=32\pi\ in^{3}$

<em>Find the volume of 3/4 of the glass</em>

$32\pi (\frac{3}{4})=24\pi\ in^{3}$

step 3

Divide the total volume of cylindrical can by the 3/4 volume of the glass

$192\pi\ in^{3}/24\pi\ in^{3}=8\ glasses\ of\ juice$

Help me out here please I need help

torisob [31]

Answer:

the third option would be the best

1/10 + 3/8 = 19/40 = .475

correct answer------------ 1/6 + 1/8 = 7/24 = .291

2/9 + 1/8 = 25/72 = .347
