The volume of the paperweight will be 79.17 cubic inch

A solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms is known as prism

The steps are as follow:

∴ Area of floor = Area of triangle = ah/2

Where a=5 and h=5 from figure given

∴ Area of floor = (5*5)/2 = 12.5 sq.inch

[tex]V_{1} = \frac{1}{3}sh \\V_{1} = \frac{1}{3}*7*\frac{1}{2}*5*5\\V_{1} = 29.17[/tex]

[tex]V_{2} = sh\\V_{2} = 4*\frac{1}{2}*5*5 \\V_{2} = 50[/tex]

∴ Total volume

[tex]=50+29.17\\=79.17[/tex]

Therefore the total volume of paperweight will be 79.17 cubic inch

Answer:

Number of nickels: 2,

Number of dimes: 6

Step-by-step explanation:

Say d ⇒ number of dimes, n ⇒ number of nickels; from this we can formulate two equation knowing the cost per dime ⇒ $ 0.1, and the cost per nickel ⇒ $0.05

d + n = 8,

0.1 * d + 0.05 * n = 0.7 ⇒ Let us solve through substitution

d = 8 - n into 0.1 * d + 0.05 * n = 0.7,

0.1 * ( 8 - n ) + 0.05 * n = 0.7,

0.8 - 0.1 * n + 0.05 * n = 0.7,

0.8 - 0.1n + 0.05n = 0.7,

- 0.05n = - 0.1,

Number of nickels: 2 ⇒ Now let us substitute this value into the first equation as to solve for d, dimes

d = 8 - 2,

Number of dimes: 6

Answer:

In total there are 30 cups and there are 2 left over

Step-by-step explanation:

The first thing is to clarify the equivalences, we have to:

1 gallon = 4 quarts

1 quart = 2 pints

1 pint = 2 cups

We will pass everything to cups,

1 gallon of orange juice = 16 cups

3 pints of pineapple juice = 6 cups

2 quarts of lemon ‐ lime soda = 8 cups

So in total they would be 16 + 6 + 8 = 30 cups

How to get 2 cups for 14 guests in total would be 28 cups, which means that if 2 cups are left and left over.

The volume of a sphere with a radius of 9.9 ft is 4062.3 cubic foot.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

The volume of the sphere is 4/3πr³

Radius is 9.9 ft.

Volume =4/3×3.14×(9.9)³

=4/3×3.14×970.3

=12187/3

=4062.3

Hence, the volume of a sphere with a radius of 9.9 ft is 4062.3 cubic foot.

Answer:

a) Total distance travelled to the nearest foot = 105ft

b) First 5 terms = 12, 9, 6.75, 5.0625, 3.796875

Step-by-step explanation:

From the question above, we can see that this is a geometric series or progression

Formula for geometric progression:

Tn = arⁿ-¹

Where

a = first term

r = common ration

n = number of terms

From the question, we are told that the ball dropped from 16 feet

Hence First term(a) = 16

We are told that the ball rebounds to 3/4 of it's previous height anytime it hits the surface.

Hence, common ratio(r) = 3/4

a) We are told to find total distance to the nearest foot that the ball travelled when it strikes the ground for the 10th time

This means we are to find the sum of the first 10 terms.

Because the ball rises and falls, we would use the rises form

Where the first term = 12 and the number of times is 9 because it rises 9 times

The formula we would use to find this sum is based on if the common ratio is less than or greater than 1

Our common ratio = 3/4, hence it is less than 1.

When r< 1, sum of n terms =

Sn = a(1 - rⁿ)/ 1 - r

It is important to

Where a = 12

r = 3/4

n = 9

Sn = 12( 1 - (3/4)^9) / 1- 3/4

Sn = 104.79ft

Approximately = 105ft

b) First five terms

Using the formula

Tn = arⁿ-¹

Where

a = first term = 12

r = common ration

n = number of terms

First term, n = 1 = 12 × 3/4^(1-1)

= 12 × 3/4 ^(0)

= 12× 1

= 12

Second term, n = 2 = 12 × 3/4^(2-1)

= 12 × 3/4 ^(1)

= 36/4

= 9

Third term, n = 3 = 12 × 3/4^(3-1)

= 12 × (3/4)²

= 6.75

Fourth term, n = 4= 12 × 3/4^(4-1)

= 12 × (3/4)³

= 5.0625

Fifth term, n = 5 = 12 × 3/4^(5-1)

= 12 × (3/4)⁴

= 3.796875

Therefore, the first 5 terms = 12, 9, 6.75, 5.0625, 3.796875

The rebound of the ball from the height is an illustration of a geometric series

(a) The total vertical distance

The given parameters are:

[tex]\mathbf{a = 16}[/tex] -- the first term

[tex]\mathbf{r = \frac 34}[/tex] -- the common ratio

[tex]\mathbf{n = 10}[/tex] -- number of terms

The total vertical distance when it strikes for the 10th time is the sum of nth terms of the geometric series.

So, we have:

[tex]\mathbf{S_n = \frac{a(1 - r^n)}{1- r}}[/tex]

Substitute values for (a), (r) and n

[tex]\mathbf{S_{10} = \frac{16(1 - 3/4^{10)}}{1- 3/4}}[/tex]

Simplify

[tex]\mathbf{S_{10} = \frac{16(0.943)}{0.25}}[/tex]

[tex]\mathbf{S_{10} = 60.352}[/tex]

Hence, the total vertical distance at the 10th rebound is 60.352 feet

(b) The first five terms of this sum

The nth term of a geometric series is:

[tex]\mathbf{T_n = ar^{n-1}}[/tex]

So, we have:

[tex]\mathbf{T_1 = 16}[/tex]

[tex]\mathbf{T_2 = 16 * 3/4 = 12}[/tex]

[tex]\mathbf{T_3 = 12 * 3/4 = 9}[/tex]

[tex]\mathbf{T_4 = 9 * 3/4 = 6.75}[/tex]

[tex]\mathbf{T_5 = 6.75 * 3/4 = 5.0625}[/tex]

Hence, the first five terms of the sum are 16, 12, 9, 6.75 and 5.0625
