Answer:

First we Check if its an AP or GP

Its an AP because the Second term Minus the First term is = to 3rd term Minus Second term

Since it said "Sum"

The formula we should think Of is

Sn = n/2[2a + (n-1)d]

n=100

a(First term) =100

Common difference 'd' = Second term - First term or Third term - Second term

So

d= 98-100 or 96-98

d=-2.

Applying the Formula...

Sn = 100/2 [2(100) + (100-1)(2)]

Sn = 50[200 + (99)(2)]

Sn= 50[200 + 198]

Sn = 50[398]

Sn = 19,900.

Answer:

B

Step-by-step explanation:

For the given situation, system of equations is represented by

3x + 4y = 4.25

5x + 2y = 4.75

"A system of equations is a finite set of equations for which we find the common solution."

According to question,

x represents number of apples

y represents number of oranges.

Two situations are given for which we need to find out which system of equations it represents.

Situation 1 : Thomas paid $4.25 for the three apples and four oranges , which can be represented by equation:

3x + 4y = 4.25

Situation 2: Casey paid $4.75 for five apples and two oranges, which can be represented by equation:

5x + 2y = 4.75

Hence we can conclude that Option B is correct.

Step-by-step explanation:

Answer:

r = 10.5

Step-by-step explanation:

using the Pythagorean theorem:

(7 + r)² = 14² + r²

49 + 14r + r² = 196 + r²

subtract r² from both sides of the equation:

14r + 49 = 196

subtract 49 from both sides:

14r  = 147

divide both sides by 14:

r = 10.5

Complete question :

The dimensions of a right rectangular prism are 1.5 cm, 0.5 cm and 2. 25 cm.

What is the volume of the prism?

A. 0.75 cm

B. 1.6875 cm

C. 3.375 cm

D. 4.25 cm

Answer:

1.6875 cm³

Step-by-step explanation:

Given the dimension :

1.5 cm by 0.5 cm by 2.25 cm

The volume of a rectangular prism is given by :

Volume = Length * width * height

Volume, V = 1.5cm * 0.5cm * 2.25cm

Volume of prism = 1.6875 cm³

Hence, the volume of the rectangular prism is 1.6875 cm³

Answer:

Klean company = 20 + 25h

Dustbuster cleaning services = 35h

Step-by-step explanation:

Let

Number of hours = h

Equation to calculate the cost of cleaning your house

Klean company = 20 + 25h

Dustbuster cleaning services = 35h

Find the number of hours when the cost of cleaning house by both companies will be equal

Klean company = Dustbuster cleaning services

20 + 25h = 35h

20 = 35h - 25h

20 = 10h

h = 20/10

h = 2 hours

Number of hours = h = 2 hours

The diameter of the hemisphere is twice the radius,

d = 2r ≈ 16.6 inches

Volume is the measure of the amount of space occupied by a three-dimensional object. It is usually expressed in cubic units, such as cubic meters, cubic feet, or cubic centimetres.

The volume of a hemisphere is given by V = (2/3)πr³, where r is the radius of the hemisphere.

We can solve for the radius as follows:

V = (2/3)πr³

863 = (2/3)πr³

r³ = (863 x  3) / (2π)

r³ ≈ 650.35

r ≈ 8.3 inches

The diameter of the hemisphere is twice the radius, so:

d = 2r ≈ 16.6 inches

Answer:

Exponential

Step-by-step explanation:

So lets look at the table.

When x = 1, y = 3

When x = 2, y = 9.

Hmmm, this doenst seem like x+number=y. It doesnt seem like a quadratic, where the values go up, then down, then up again. Or vise versa.

So this rules out linear and quadratic, for the x doesnt change by a constant, or change the direction of y.

This leaves exponential or none of the above.

When x = 3, y = 27

When x = 4, y = 81

This seems like a exponent, since:

3 to the first power is 3

3 to the second power is 9

3 to the third power is 27

and 3 to the fourth power is 81

Answer:

============================================================

Explanation:

Part (a)

A regular triangular pyramid, aka regular tetrahedron, has all four triangles that are identical copies of one another. They are congruent triangles. This will apply to part (b) as well.

To find the area of one of the triangles, we'll use the formula

A = 0.25*sqrt(3)*x^2

where x is the side length. This formula applies to equilateral triangles only.

In this case, x = 20, so

A = 0.25*sqrt(3)*x^2

A = 0.25*sqrt(3)*20^2

A = 173.20508 approximately

That's the area of one triangle, but there are four total, so the entire area is about 4*173.20508 = 692.82032 which rounds to 693 sq cm.

The units "sq cm" can be written as "cm^2".

----------------------------

Part (b)

We'll use the same idea as part (a). But the formula to find the area of one triangle is much simpler.

The area of one of the triangles is A = 0.5*base*height = 0.5*6*4 = 12 sq cm.

So the area of all four triangles combined is 4*12 = 48 sq cm

This area is exact.

The area of each 2D flat net corresponds exactly to the surface area of each 3D pyramid. This is because we can cut the figure out and fold along the lines to form the 3D shapes.

Answer:

3360ft^3

Step-by-step explanation:

Volume of each trailer = 20ft * 7ft *8ft

Volume of each trailer = 140*8

Volume of each trailer = 1120ft^3

Since there are 3 of such cargo;

Capacity of the trailer =3(1120)

Capacity of the trailer  = 3360ft^3

Hence the capacity of the trailer is 3360ft^3
