What is the volume of metal in the hex nut, to the nearest tenth? use 3.14 for π. 21.1 cm3 23.6 cm3 27.6 cm3 31.6 cm3

Answers

The volume of metal in the hex nut to the nearest tenth is 27.6 cm^3.

Calculations and Parameters:

Given that:

Diameter of the cylinder: d=1.6 cmApothem of the hexagon: a=2 cmAssuming the thickness of the steel hex nut: t=2 cmVolume of metal in the hex nut: V=?V=Vp-VcVolume of the prism: VpVolume of the cylinder: Vc

The central angle in the hexagon: A=360°/n

A=360°/6A=60°tan (A/2)=(L/2) / atan (60°/2)=(L/2) / (2 cm)tan 30° = (L/2) / (2 cm)\sqrt(3)/3=(L/2) / (2 cm)

Solving for L/2:

(2 cm) \sqrt(3)/3 = L/22 \sqrt(3)/3 cm = L/2

Solving for L:

2 (2 \sqrt(3)/3 cm)=L4 \sqrt(3)/3 cm = LL=4 \sqrt(3)/3 cm

Ab=n L a / 2Ab=6 (4 \sqrt(3)/3 cm)(2 cm) / 2Ab=24 \sqrt(3)/3 cm^2Ab=8 \sqrt(3) cm^2

Vp=Ab hVp=(8 \sqrt(3) cm^2)(2 cm)Vp=16 \sqrt(3) cm^3Vp=16 (1.732) cm^3(1) Vp=27.712 cm^3

Cylinder:

Vc=(π d^2/4) hπ=3.14d=1.6 cmHeight of the cylinder: h=t=2 cm

Vc=[3.14 (1.6 cm)^2 / 4] (2 cm)Vc=[3.14 (2.56 cm^2) / 4] (2 cm)Vc=(2.0096 cm^2) (2 cm)Vc=4.019 cm^3

Vada places a box of toys and a box of books together. The box of toys has a length of 5 feet, a width of 3 feet, and a height of 2 feet. The box of books has a length of 6 feet, a width of 4 feet, and a height of 2 feet. What is the combined volume of the boxes?

Answers

Answer:

78 ft cubed

Step-by-step explanation:

First calculate the volume of the toys...

5 x 3 x 2 = 30

Now the book boxes...

6 x 4 x 2 = 48

30 + 48 = 78

The combined volume should be 78 feet cubed! hope this helps!!!

Answer:

78 ft³

Step-by-step explanation:

Volume of a rectangular prism = length × width × height

Toy Box

length = 5 ftwidth = 3 ftheight = 2ft

⇒ volume = 5 × 3 × 2 = 30 ft³

Book Box

length = 6 ftwidth = 4 ftheight = 2 ft

⇒ volume = 6 × 4 × 2 = 48 ft³

Total combined volume = 30 + 48 = 78 ft³

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number of cases ordered by Camp Copeland be = 20 cases

Let the number of eggs in each case = 12 eggs

So , the equation will be

The number of eggs in 20 cases A = 20 x number of eggs in each case

Substituting the values in the equation , we get

The number of eggs in 20 cases A = 20 x 12

The number of eggs in 20 cases A = 240 eggs

Therefore ,  the value of A is 240 eggs

Hence , the number of eggs is 240 eggs

Alex is mowing a 145.5 square feet law. He used 3/4 gallon of as to mow 3/10 of the law. How many gallons of gas are needed to mow the entire lawn?

Answers

Answer:

2.5 gallons of gas

Step-by-step explanation:

Note : we have a proportional relationship between the two variables

_______________________________________

He used 3/4 gallon of gas to mow 3/10 of the lawn

Then

He has to use 1/4 gallon of gas in order to mow 1/10 of the lawn

( we divided both sides by 3)

Then

He has to use 10 × 1/4 gallons of gas to mow 10/10 of the lawn

What that means is :

He has to use 10/4 gallons of gas to mow the entire lawn

In other words :

He has to use 2.5 gallons of gas to mow the entire lawn

What is the length of the hypotenuse? If necessary, round to the nearest tenth.
C =

Answers

Answer:

Step-by-step explanation:

Answer:

C^2 = 95 ft is the length of the hypotenuse.

Step-by-step explanation:

To get the hypotenuse, apply the Pythagorean theorem.

The formula is a^2+b^2=c^2, where a and b are the leg lenths and c is the length of the hypotenuse. This is referred to as the Pythagorean theorem.

We know what a and b are, so lets utilize the Pythagorean theorem

.

a^2 + b^2 = c^2 - This is the Pythagorean theorem formula.

76^2 + 57^2 = C^2 - Fill in the equation with a= 76 and b = 57^2.

5776 + 3249 = c^2

9025 = c^2 -   C^2  is found by adding A^2 and B^2.

square root of c^2 = square root of 9025 - Take the square root of both sides of the equation.

C = 95 ft  - Simplify

C^2 = 95 ft is the length of the hypotenuse. Brainliest? :D

Question:

Can anyone help me been stuck for a while.

Answer:

[tex]\frac{4}{9}[/tex]

Step-by-step explanation:

The bag has 15 white marbles,

and 12 blue marbles.

Add the totals together, and you would get:

27.

turn that into a fraction:

[tex]\frac{12}{27}[/tex]

then simplify:

Find the GCD (or HCF) of numerator and denominator

GCD of 12 and 27 is 3

Divide both the numerator and denominator by the GCD

12 ÷ 3

27 ÷ 3

Reduced fraction:

[tex]\frac{4}{9}[/tex]

Therefore, [tex]\frac{12}{27}[/tex] simplified to lowest terms is:

[tex]\frac{4}{9}[/tex]

Therefore, your answer would be: [tex]\frac{4}{9}[/tex]

There is a pair of parallel sides in the following shape. 4 4 6 What is the area of the shape?​

Answers

Answer:  20

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

Explanation:

It might help to rotate the figure so the parallel sides are horizontal. This is optional.

The parallel bases are [tex]b_1 = 6[/tex] and [tex]b_2 = 4[/tex] in either order.

The height is h = 4 which is always perpendicular to both bases.

Plug these values into the trapezoid area formula.

[tex]A = \frac{h(b_1 + b_2)}{2}\\\\A = \frac{4(6+4)}{2}\\\\A = \frac{4(10)}{2}\\\\A = \frac{40}{2}\\\\A = 20\\\\[/tex]

The area of the trapezoid is 20 square units.

-----------

Another pathway is to break the trapezoid into a rectangle up top and a triangle down below.

The rectangle is 4 by 4 with area 4*4 = 16

The triangle has a base of 6-4 = 2 and height of 4, so its area is base*height/2 = 2*4/2 = 8/2 = 4

Overall the total area is rectangle+triangle = 16+4 = 20 square units.

Determine formula of the nth term 2, 6, 12 20 30,42​

Answers

Check the forward differences of the sequence.

If [tex]\{a_n\} = \{2,6,12,20,30,42,\ldots\}[/tex], then let [tex]\{b_n\}[/tex] be the sequence of first-order differences of [tex]\{a_n\}[/tex]. That is, for n ≥ 1,

[tex]b_n = a_{n+1} - a_n[/tex]

so that [tex]\{b_n\} = \{4, 6, 8, 10, 12, \ldots\}[/tex].

Let [tex]\{c_n\}[/tex] be the sequence of differences of [tex]\{b_n\}[/tex],

[tex]c_n = b_{n+1} - b_n[/tex]

and we see that this is a constant sequence, [tex]\{c_n\} = \{2, 2, 2, 2, \ldots\}[/tex]. In other words, [tex]\{b_n\}[/tex] is an arithmetic sequence with common difference between terms of 2. That is,

[tex]2 = b_{n+1} - b_n \implies b_{n+1} = b_n + 2[/tex]

and we can solve for [tex]b_n[/tex] in terms of [tex]b_1=4[/tex]:

[tex]b_{n+1} = b_n + 2[/tex]

[tex]b_{n+1} = (b_{n-1}+2) + 2 = b_{n-1} + 2\times2[/tex]

[tex]b_{n+1} = (b_{n-2}+2) + 2\times2 = b_{n-2} + 3\times2[/tex]

and so on down to

[tex]b_{n+1} = b_1 + 2n \implies b_{n+1} = 2n + 4 \implies b_n = 2(n-1)+4 = 2(n + 1)[/tex]

We solve for [tex]a_n[/tex] in the same way.

[tex]2(n+1) = a_{n+1} - a_n \implies a_{n+1} = a_n + 2(n + 1)[/tex]

Then

[tex]a_{n+1} = (a_{n-1} + 2n) + 2(n+1) \\ ~~~~~~~= a_{n-1} + 2 ((n+1) + n)[/tex]

[tex]a_{n+1} = (a_{n-2} + 2(n-1)) + 2((n+1)+n) \\ ~~~~~~~ = a_{n-2} + 2 ((n+1) + n + (n-1))[/tex]

[tex]a_{n+1} = (a_{n-3} + 2(n-2)) + 2((n+1)+n+(n-1)) \\ ~~~~~~~= a_{n-3} + 2 ((n+1) + n + (n-1) + (n-2))[/tex]

and so on down to

[tex]a_{n+1} = a_1 + 2 \displaystyle \sum_{k=2}^{n+1} k = 2 + 2 \times \frac{n(n+3)}2[/tex]

[tex]\implies a_{n+1} = n^2 + 3n + 2 \implies \boxed{a_n = n^2 + n}[/tex]

Let the amount of money she needs in addition to pay for her education be ,'x'.

Then,

According to the question,

Amount they have saved + amount they're going to save per month for next 4 years + the financial aid = Total amount they need

$50,000+ $250 x 12 x 4 + x = $72,000$50,000 + $12,000 + x = $72,000$62,000 + x = $72,000x = $72,000-$62,000x = $10,000
