Answer:

640 units squared

Step-by-step explanation:

The shape below is a trapezoid.

The formula for the area of a trapezoid is average of the bases times the height.

The bases are the parallel lines that make up 2 of the sides of the trapezoid.

The height is the line dotted line that creates right angles and is the distance between the two bases.

The bases are 24 and 40.

To find the average, we add them together and divide by 2

(24+40)/2=64/2=32

Now, we multiply 32 by the height, which is given as the length of 20.

32*20=640

the area of the trapezoid is 640 units squared

Hope this helps!

AB bisects CD at point M, CD bisects AB at point M, and AB = 4 x CM. Describe the relationship between AM and CD

padilas [110]

$\text{Given that AB bisects the line segment CD at the point M,}\\
\text{And CD bisects the line segment AB at the point M. so M is the }\\
\text{midpoint of both the line segements AB and CD.}\\
\\
\text{also we have given a relation that, }AB=4\times CM\\
\text{and we need to find a relation between AM and CD.}\\
\\
\text{observe that since M is the midpoint of CD, so we have }CD=2\times CM\\
\\
\Rightarrow CM=\frac{CD}{2}$

$\text{and M is midpoint of AB, so }AB=2\times AM\\
\\
\text{so with these substitutions, the given realtion gives}\\
\\
AB=4\times CM\\
\\
\Rightarrow 2\times AM=4\times \frac{CD}{2}\\
\\
\Rightarrow 2\times AM=2\times CD\\
\\
\Rightarrow AM=CD$

Hence the relationship between AM and CD is : AM=CD

Which expression equals 9^3 sqrt 10

irinina [24]

Answer:

Option B is correct.

$5\sqrt[3]{10} + 4\sqrt[3]{10}$

Step-by-step explanation:

Given the equation: $9\sqrt[3]{10}$

We can write 9 as:

9 = 5+ 4

then;

$(5+4)\sqrt[3]{10}$

Using distributive property:

$a\cdot(b+c)= a\cdot b+ a\cdot c$

Apply distributive property:

$5\sqrt[3]{10} + 4\sqrt[3]{10}$

Therefore, the expression which is equivalent to $9\sqrt[3]{10}$ is $5\sqrt[3]{10} + 4\sqrt[3]{10}$

Pre image ABCD was dilated to produce image A’B’C’D why is the scale factor from the pre image? Enter your answer in the box as

shepuryov [24]

The scale factor of the dilation from ABCD to A′B′C′D′ is 3.

Step-by-step explanation:

Step 1:

In the pre-image ABCD, the length of one of the sides is given as 14 units.

For the other shape A′B′C′D′, the same side as the previous shape is given as 8 units.

Step 2:

To determine the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In this case, it is the given length of the sides CD and C′D′.

So the scale factor = $\frac{C^{1} D^{1} }{CD} = \frac{8}{14} = \frac{4}{7} .$

So the shape ABCD is dilated by a scale factor of $\frac{4}{7}$ to produce the shape A′B′C′D′.

Find volume with full working out thank you ;)

Alina [70]

Answer:

2110 cm³

Step-by-step explanation:

Volume = V1 + V2,

Where V1 is the volume of the pyramid, and V2 is the volume of half cylinder

V1 = ⅓×(Base area)×height

V1 = ⅓×(12.6×21.5)×8.5 = 767.55

V2 = ½×(pi×r²×h)

r = 12.6÷2 = 6.3

V2 = ½×(pi×6.3²×21.5) = 1340.415

Volume = V1 + V2

= 767.55 + 1340.415

= 2107.965

= 2110 cm³ (3 sf)
