Answer:

576

Step-by-step explanation:

The volume of a square pyramid is $\frac{a^2h}{3}$ , where a is the base length and h is the height. We know that a is 8 so a squared is 64. 64x27=1728, and 1728/3 is 576. So the volume of the pyramid is 576 units cubed.

Hope this helps!

What is the equation of the line, in general form, that passes through the point (1,1) and has a y-intercept of 2.

guajiro [1.7K]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept.

Put the given y-intercept b = 2 and the coordinates of the point (1, 1) to the equation:

$1=1m+2$ <em>subtract 2 from both sides</em>

$-1=m\to m=-1$

The equation of a line:

$y=-1x+2\to y=-x+2$

The general form of an equation of a line:

$Ax+By+C=0$

Convert:

$y=-x+2$ <em>add x to both sides</em>

$x+y=2$ <em>subtract 2 from both sides</em>

$x+y-2=0$

Which expression has a value that is less than the base of that experience?

Rom4ik [11]

Answer:

(B) $(\frac{5}{6})^{2}$

Step-by-step explanation:

(A) The given expression is: $2^{3}$

= $8$

The value of this expression is 8 which is greater than the base of the expression that is 2.

(B) The given expression is: $(\frac{5}{6})^{2}$

= $\frac{25}{36}$

= $0.09$

The value of this expression is 0.09 which is smaller than the base of the given expression that is 0.83.

= $9$

The value of this expression is 9 which is greater than the base of the given expression that is 3.

(D) The given expression is: $4^{4}$

= $256$

The value of this expression is 256 which is greater than the base of the given expression that is 4.

Hence, Option B is correct.

If 3x = y -5 and x = 4, then y =

Vinil7 [7]

Answer:

y = 17

Step-by-step explanation:

3x = y - 5, for x = 4

=> 3(4) = y - 5

=> 12 = y - 5

=> 12 + 5 = y

=> 17 = y
