Answer:

B. 5 cm3

Step-by-step explanation:

The volume of the oblique pyramid with a square base is 3.33 cm³.

Suppose the base of the pyramid has length = l units, and width = w units.

Suppose that the height of the pyramid is of h units, then:

[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]

is the volume of that pyramid.

The base is a rectangle with length = L units, and width = W units, so its area is:

[tex]b = l \times w\: \rm unit^2[/tex]

We are given that;

the base is about 2 cm long and that the height is about 2.5 cm long.

Now,

Using these values, we can estimate the volume as:

V ≈ (1/3) × Base Area × Height

V ≈ (1/3) × (2 cm)² × 2.5 cm

V ≈ (1/3) × 4 cm² × 2.5 cm

V ≈ 10/3 cm³

V ≈ 3.33 cm³

Therefore, an approximate volume of the pyramid will be 3.33 cm³.

Step-by-step explanation:

A. is correct! Good job!

The correct answer is D.  I found the equation,  y = 6x + 1 and solved each one till it fit.  y + 5 = 6(x + 1)

Answer:

g(q) = 5/8q

Step-by-step explanation:

-7q + 12r = 3q - 4r

Add 4r to each side

-7q + 12r+4r  = 3q - 4r+4r

-7q +16r = 3q

Add 7q to each side

-7q+7q +16r = 3q+7q

16r = 10q

Divide each side by 16

16r/16 = 10q/16

r = 5q/8

g(q) = 5/8q

Step-by-step explanation:

Answer:

the alternative interior angles are c and e

Answer:

a. 28.

b 20.78.

Step-by-step explanation:

a. f(x) = 0.001(x -  10)(x + 20)(x - 40)

When x = 50

Height = f(40) = 0.001(50-10)(50+20)(50-40)

= 0.001(40*70*10)

= 0.001 * 28,000

= 28 units.

b.

Expanding the function we get

f(x) = 0.001(x  - 10)(x^2 - 20x - 800)

f(x) = 0.001(x^3 - 30x^2 - 600x + 8000)

f(x) = 0.001x^3 - 0.03x^2 - 0.6x + 8

Finding the derivative

f'(x) = 0.003x^2 - 0.06x - 0.6

This is zero for maxm/minm values:

0.003x^2 - 0.06x - 0.6 = 0

x = 27.32, - 7.32.

The values of the heights corresponding to these values of x are:

0.001(27.32-10)(27.32+20)(27.32-40)

= -10.39. and

0.001(-7.32-10)(-7.32+20)(-7.32-40)

= 10.39.

So the distance between A and B =  10.39 - (-10.39)

= 20.78.

Step-by-step explanation:

Find the mean of the 2 given values

mean = [tex]\frac{25+9}{2}[/tex] = [tex]\frac{34}{2}[/tex] = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = [tex]\frac{25+17}{2}[/tex] = [tex]\frac{42}{2}[/tex] = 21 and

mean = [tex]\frac{17+9}{2}[/tex] = [tex]\frac{26}{2}[/tex] = 13

Thus the 3 means are 21, 17 and 13, that is

Answer:

About 78.1 square centimeters

Step-by-step explanation:

First, you need to find the areas of each individual shape, and then to subtract  one from the other. The area of the circle is [tex]\pi r^2=\pi \cdot 6^2\approx 113.1[/tex]. The area of the rectangle is [tex]7\cdot 5=35[/tex]. Subtracting this from the area of the circle, you get about 78.1 centimeters. Hope this helps!

Answer:

[tex]78.09 {cm}^{2} [/tex]

Step-by-step explanation:

First find the area of the circle

[tex]\pi {r}^{2} \\ \pi \times 6 \times 6 \\ = 113.09[/tex]

Now find the area of the rectangle

[tex]b \times h \\ = 5 \times 7 \\ = 35[/tex]

Now subtract the area of the rectangle from the area of the circle.

You'll get the area of the shaded region.

[tex]113.09 - 35 \\ = 78.09 {cm}^{2} [/tex]

Answer:

1149.8 m³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )

Here diameter = 13, thus radius = 13 ÷ 2 = 6.5

V = [tex]\frac{4}{3}[/tex] × 3.14 × 6.5³

   = [tex]\frac{4}{3}[/tex] × 3.14 × 274.625

   = [tex]\frac{4(3.14)(274.625)}{3}[/tex] ≈ 1149.8 m³ ( to the nearest tenth )

Answer:

The radius of the base of the small cone is 3 feet

Step-by-step explanation:

The question requires the determination of the radius of the smaller cone

Therefore, height of the larger cone = 10 feet

Base diameter of the larger cone = 10 feet

Height of horizontal plane of small plane above base of larger cone = 4 feet

Hence the height of the small cone = 6 feet

Therefore, by similar triangles, and tangents we have;

[tex]\frac{Height \, of \, small \, cone}{Height \, of \, larger\, cone} =\frac{Diameter \, of \, base \, of \, small \, cone}{Diameter \, of \, base \, of \, larger \ cone} =\frac{6}{10} = \frac{x}{10}[/tex]

Where:

x = The diameter of the base of the small cone

Therefore;

[tex]{x} = \frac{6}{10} \times 10 = 6 \, feet[/tex]

The radius of the base of the small cone = half the diameter of the base of the small cone

∴ The radius of the base of the small cone = (6 feet)/2 = 3 feet.

Answer:

the radius would be 3

Step-by-step explanation:

so what it's saying si there;s a cone with diameter 10 and height 10, the 4 feet above the bottom of the cone is the base of the smaller cone. The height of the smaller cone becomes 6, making the diameter 6 as the ratio becomes 6:6, and radius is diameter/2 becoming 3
