Decreased by 25%
find 25% of 12 and decrease 12 by it

percent means parts out of 100
25%=25/100=1/4
'of' means multiply
25% of 12=1/4 times 12=3

decrease 12 by 3
12-3=9

Problem1 a right square frustum is formed by cutting a right square pyramid with a plane parallel to its base. Suppose the origi

timama [110]

Answer:

Volume of the frustum is 76 unit³

Step-by-step explanation:

From the figure attached we have to calculate the volume of the frustum formed by cutting off a square pyramid from the top.

Volume of the frustum = $\frac{1}{3}\text{(area of the base with side 6 units)(height)}-\frac{1}{3}\text{(area of the base with side MN)}(Height)$

Since ΔAPO' and ΔAOQ are similar so

$\frac{AO}{AO'}= \frac{OQ}{O'P}$

$\frac{9}{6}= \frac{3}{O'P}$

O'P = $\frac{3\times6}{9}=2$ units

Therefore, side MN = 2× O'P = 4 units

Now we put these values in the formula

Volume of the frustum = $\frac{1}{3}(6\times6)(9)}-\frac{1}{3}(4\times4)(6)$

= $\frac{1}{3}(324)-(\frac{1}{3}\times96)$

= $\frac{324}{3}-\frac{96}{3}$

= $\frac{324-96}{3}=\frac{228}{3}$

= 76 unit³

Answer:

y=2/3x-4

Step-by-step explanation:

we can see that x goes up 1 for every 1.5y and if we start y at 0 x starts at -4 so if y is one than x has to be 2/3-4 becuase it is -4 + 2/3 for every 1 y goes up or one for every 1.5 y goes up. hope this answer was helpful.

The line is 180 degrees you know you have a right angle and a 64 degree angle. Add 63 and 90 (right angle) then subtract from 180
180-154= 26 degrees
