Answer the question to become brainliest

marishachu [46]

Answer:

2406.17 cm³

Step-by-step explanation:

The following data were obtained from the question:

Height (h) = 24.4 cm

Base length (L) = 17.2 cm

Volume (V) =?

Next, we shall determine the base area of the pyramid. This can be obtained as follow:

Base length (L) = 17.2 cm

Base area (B) =.?

B = L × L

B = 17.2 × 17.2

B = 295.84 cm²

Finally, we shall determine the volume of the pyramid. This can be obtained as follow:

Height (h) = 24.4 cm

Base area (B) = 295.84 cm²

Volume (V) =?

V = ⅓Bh

V = ⅓ × 295.84 × 24.4

V = 2406.17 cm³

Thus, we volume of the pyramid is 2406.17 cm³

The coordinates of the endpoints of AB and CD are A(2,

Ratling [72]

Answer:

Option 1: CD is a perpendicular bisector of AB

Step-by-step explanation:

Let us find out the slopes of various line segments and the Distances and then we will draw the conclusions accordingly.

Formula to find slope

$m= \frac{y_2-y_1}{x_2-x_1}$

Formula to Find Distance between two points

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

mAB ( represents , Slope of AB )

1. $mAC= \frac{3-2}{2-5}=\frac{1}{-3}=-\frac{1}{3}$

2. $mBC=\frac{2-1}{5-8}=\frac{1}{-3}=-\frac{1}{3}$

3. $mCD=\frac{5-2}{6-5}=\frac{3}{1}=3$

4. $AC=\sqrt{(3-2)^2+(2-5)^2} =\sqrt{(1)^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}$

5. $BC=\sqrt{(2-1)^2+(5-8)^2} =\sqrt{(1)^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}$

mAC = mBC , and C is common point , hence these three are collinear points making a straight line whole slope is $-\frac{1}{3}$

$mAB=-\frac{1}{3}$

$mCD=3$

$mAB \times mCD = -\frac{1}{3} \times 3 = -1$

Hence CD ⊥ AB

Also

From Point 4 and point 5 above , we see that

AC = CB

Hence CD bisect AB at C, also CD ⊥ AB

There fore

CD is a perpendicular bisector of AB

Therefor option 1 is true

How do yo work out 9.1 divided by 3575

EastWind [94]

9.1/3575
use long division like this
 _0._________
3575|91.000000

we find how many of 3575 fit into the 91
it's too big so we go farther
how many 3575 go into 910
too big so we go farther
how many 3575 go into 9100
the answer is 2 so put that in the correct place and mulitply that and put that in the correct place. then we subtract

 _0.02_________
3575|91.000000
 -71.50
 19.50
bring down the next number
find how many go into 19.500
the answe ris 5

 _0.025_________
3575|91.000000
 -71.50
 19.500
 -17.875
 1.625

bring down he next zero ( I fast forward and skip steps for convinience)

 __
 _0.025455_________
3575|91.000000
 -71.50
 19.500
 -17.875
 1.6250
 -1.4300
 .19500
 -.17875
 16250
 -14300
and so on untill infinity so the answe ris 0.0254555555555555 (enless fives)
