Answer:

[tex]V=210\ cm^3[/tex]

Step-by-step explanation:

The legs measuring 10 cm and 14 cm.

The height of the pyramid is 9 cm.

We need to find the volume of the pyramid. The formula for the volume of a right pyramid is given by :

[tex]V=\dfrac{1}{3}Bh[/tex]

Where

B is area of base,

[tex]B=\dfrac{1}{2}\times 10\times 14=70\ cm^2[/tex]

Put all the values,

[tex]V=\dfrac{1}{3}\times 70\times 9\\\\V=210\ cm^3[/tex]

So, the volume of the right pyramid is equal to [tex]210\ cm^3[/tex].

Answer:

A

Step-by-step explanation:

Geometry

The answer is A, due to 3 and 2 being vertical.

Answer:

B

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{?}{6}[/tex] = [tex]\frac{18}{12}[/tex] ( cross- multiply )

12 ? = 108 ( divide both sides by 12 )

? = 9 → B

Answer:

89*

Step-by-step explanation:

To find the value of m<1, you need to find the angle right next to it (the third interior angle that isn't labeled).

To find that angle (let's call it x), we have to use an equation.

Since a triangle has a sum of 180* for the interior angles in it, then we can use that to solve for x.

x + 53 + 36 = 180

x + 89 = 180

x = 91

Now to find m<1, we need to use the supplementary angles theorem.

Since m<1 and x are supplementary angles, the sum of those angles would be 180. Using this, we can create an equation.

x + m<1 = 180

91 + m<1 = 180

m<1 = 89

Hence, m<1 is 89*!

Answer:

102 mph

Step-by-step explanation:

Eliana travels at an average speed of 50 mph for 60 miles.

Without stopping, Eliana then travels 130 miles in 2.5 hours.

We calculate the speed here

Speed = Distance in miles /Time in hours

Speed = 130 miles/2.5 hours

= 52 miles per hour

Hence, her average speed for the entire journey is calculated as:

50 mph + 52 mph

= 102 mph

Given:

Volume of sphere = 1200 cm³

The sphere is dilated by a factor of [tex]\dfrac{3}{5}[/tex].

To find:

The volume of the dilated image.

Solution:

If two figures are similar then their volumes are proportional to cube of their corresponding sides.

We know that all sphere are similar to each other.

The sphere is dilated by a factor of [tex]\dfrac{3}{5}[/tex]. It means the ratio of new figure to original figure is

Let [tex]V_1[/tex] be the volume of original figure and [tex]V_2[/tex] be the volume of dilated figure.

[tex]\dfrac{V_2}{V_1}=\left(k\right)^3[/tex]

Where, k is the scale factor.

[tex]\dfrac{V_2}{1200}=\left(\dfrac{3}{5}\right)^3[/tex]

[tex]\dfrac{V_2}{1200}=\dfrac{27}{125}[/tex]

Multiply both sides by 1200.

[tex]V_2=\dfrac{27}{125}\times 1200[/tex]

[tex]V_2=259.2[/tex]

[tex]V_2\approx 259[/tex]

Therefore, the volume of the dilated image is 259 cubic centimetres.

Answer:

231.04 ft²

Step-by-step explanation:

Area triangle = 1/2( 11.4 * 15.2)

Area triangle = 1/2( 173.28 )

Area triangle = 86.64 ft²

Area rectangle = 19 x 7.6

Area rectangle = 144.4 ft²

Area total = 86.64 ft² + 144.4 ft² = 231.04 ft²

Answer:

x=20

Step-by-step explanation:

Since AB is a line it forms 180,

Set your formula up as

180=60+4x+40

180-60-40=4x

80=4x

80/4=x

Answer:

The center is (2, -7)

Step-by-step explanation:

A circle is given by

(x-h)^2 + (y-k)^2 = r^2

where(h,k) is the center and r is the radius

(x - 2)^2 +(y + 7)^2 =169

(x - 2)^2 +(y -  -7)^2 =13^2

The center is (2, -7) and the radius is 13

Answer:

Both of your answers are correct

Step-by-step explanation:

Answer:

d

e

Step-by-step explanation:

2x ≤ 5x - 15

step 1 subtract 5x from each side

2x - 5x = -3x

5x - 5x cancels out

we now have -3x ≤ -15

step 2 divide each side by -3

-3x / -3 = x

-15 / -3 = 5

IMPORTANT NOTE ( when you divide by a negative number you must flip the sign )

We would be left with x ≥ 5

now let's Plug in 10

2(10) ≤ 5(10) - 15

2(10) = 20

20 ≤ 5(10) - 15

5(10) = 50

20 ≤ 50 - 15

50 - 15 = 35

20 ≤ 35 ✓

Answer:

48

Step-by-step explanation:

1 feet = 12 inches

4 feet = 48 inches

Why?

4 x 12 = 48

I believe it's A, C and D.

Answer:

x = 4 , y = -1

Step-by-step explanation:

x - 3y = 7 -- (1)

3x - 3y = 15 -- (2)

Rewriting (1), x = 3y + 7 -- (1)'

Substituting (1)' into (2),

3 ( 3y + 7 ) - 3y = 15

9y + 21 - 3y = 15

6y = -6

y = -1 -- (3)

Substituting (3) into (1),

x - 3 ( - 1 ) = 7

x + 3 = 7

x = 4 -- (4)

According to (3) and (4),

x = 4 , y = -1

Answer:

h > 2                   or  h < 1

Step-by-step explanation:

|2h-3| >1

Solve 2 inequalities

2h-3 > 1  or 2h-3 < -1  (remembering to flip the inequality for the negative solution)

2h-3 > 1      or 2h-3 < -1

Add 3 to each side

2h-3+3 > 1+3  or 2h-3+3 < -1+3

2h>4              or    2h < 2

Divide by 2

2h/2>4/2              or    2h/2 < 2/2

h > 2                   or  h < 1

Answer:

100pi m or approximately 314 m^2

Step-by-step explanation:

We need to find the radius to find the area

r = d/2 = 20/2 = 10

The area of a circle is

A = pi r^2

A = pi (10)^2

A = 100 pi  m^2

If we approximate pi by 3.14

A = 100*3.14

A = 314 m^2

V(9, -2)

Step-by-step explanation:

U (3,8); M(6,3); V(?,?)

To go from point U to point M we went down 8-3=5 units, and to the right from 3 to 6 so 6-3=3 units. Here we got half way of the line UV so continue 5 units down and 3units right to get to V(9, -2)

U (3, 8); M(3+3= 6, 8-5= 3); V(6+3 =9, 3-5= -2)
