What is Three dimensional shape?

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

From the given triangular prism

Base side a =3 in

Base side b=3 in

Base side c=4.2

height h=7 in

The formula to find the volume of triangular prism

Volume = 1/4h√-a⁴+2(ab)²+2(ac)²-b⁴+2(bc)²-c₄

Substituting the values in the formula we get

Volume =31.4937

A piepie is divided into 2020 equal pieces. GlennGlenn and SophieSophie each ate one fourth 1 4 of the piepie on MondayMonday. The next​ day, SophieSophie ate one fifth 1 5 of the piepie that was leftover. How many of the pieces of the original piepie ​remain? Explain your reasoning. ​Together, GlennGlenn and SophieSophie ate one fourth 1 4 ​piece(s) on MondayMonday​, and SophieSophie ate one fifth 1 5 ​piece(s) the next day. To find the number of pieces that​ remain, add these numbers to the total number of pieces.​ So, 0.450.45 pieces of the original piepie remain.

Answers

Answer:

Pieces remaining =  1 - (1/4 + 1/4) - (1/2 x1/5) = 1/2 - (1/2 x1/5) = 1/2 - 1/10 = 4/10

Therefore, 4/10 x 20 = 8 pieces.

Step-by-step explanation:

Sophie ate 1/4 = 5 pieces

Glenn ate 1/4 = 5 pieces

Remaining pieces = 20 - 5 - 5 = 10 pieces

On Monday, Sophie ate = 1/5 x 10 = 2 pieces

Therefore, remaining pieces = 10 - 2 pieces = 8 pieces

Sophie and Glenn consumed half of the pie the first day.  This is equal to 10 pieces.  The remaining pieces will be 10.  If, on Monday, Sophie ate 1/5 of 10 pieces, representing 2 pieces, the number left over is 10 Minus 2, which equals 8 pieces.

Multiply the left side by 4/4 to get a common denominator

3/4*4/4 = 12/16

This is not equal to 9/16 so this is not a proportional relationship

Answer:

False

Step-by-step explanation:

3 times 3 is 9, so if this is a proportional relationship between the two fractions than 4 times 3 will be 12.

Since it is a 16 rather than a 12 you know that this cannot be right. Whatever you do to the top you have to do to the bottom, and in this case. That's just not happening.

Currency on hand = 2,000 Swiss francs Currency desired = Dutch guilders (Holland) How many guilders based on Wednesday rate? (Hint: Convert 2,000 Swiss francs to United States dollars. Then convert United States dollars into guilders.)

Answers

Answer:

4175.40384   Dutch guilders

Step-by-step explanation:

The main objective here is to convert the currency at hand (2,000 swiss francs) to Dutch guilders. In order to achieve that ; we need first require to convert the currency at hand into United states dollars

So ; if 1 swiss francs  =  1.0328 united states dollars  (as at Wednesday)

Then 2000 swiss francs  will be = 2000  ×  1.0328 united states dollars  = 2065.6 united states dollars

SO; if  1 united states dollars = 2.0214 Dutch guilders ( as at Wednesday)

Then 2065.6 united states dollars will be = 2065.6 × 2.0214

= 4175.40384   Dutch guilders

Answers

Answer:

25+8m=73

We move all terms to the left:

25+8m-(73)=0

We add all the numbers together, and all the variables

8m-48=0

We move all terms containing m to the left, all other terms to the right

8m=48

m=48/8

m=6

Answer:

[tex]m = 6[/tex]

Step-by-step explanation:

[tex]25 + 8m = 73 \\ 8m = 73 - 25 \\ 8m = 48 \\ \frac{8m}{8} = \frac{48}{8} \\ m = 6[/tex]

Solve algebraically
8x + 4y = 48
12x + 5y = 21

Answers

Answer:

[tex]x=-\frac{39}{2}\\ y=51[/tex]

Step-by-step explanation:

[tex]8x+4y=48\\12x+5y=21[/tex]

Let's solve the first equation for x or y. I'll do it for y.

[tex]8x+4y=48[/tex]

Subtract 8x

[tex]4y=-8x+48[/tex]

Divide by 4.

[tex]y=-\frac{8}{4}x+\frac{48}{4}\\[/tex]

Simplify.

[tex]y=-2x+12[/tex]

Now replace the value of y in the second equation for this.

[tex]12x+5y=21\\12x+5(-2x+12)=21[/tex]

Distribute 5

[tex]12x-10x+60=21[/tex]

Subtract 60

[tex]12x-10x=21-60[/tex]

Combine like terms;

[tex]2x=-39[/tex]

Divide by 2.

[tex]x=-\frac{39}{2}[/tex]

Now replace this in any of the equations to find the value of y.

[tex]8x+4y=48\\8(-\frac{39}{2})+4y=48\\[/tex]

8 and 2 can be simplified.

8/2=4

2/2=1

[tex]4(-39)+4y=48[/tex]

Distribute 4.

[tex]-156+4y=48[/tex]

Add 156

[tex]4y=48+156\\4y=204[/tex]

Divide by 4

[tex]y=\frac{204}{4}[/tex]

[tex]y=51[/tex]

Proof:

[tex]8x+4y=48\\8(-\frac{39}{2} )+4(51)=48\\4(-39)+204=48\\-156+204=48\\48=48[/tex]

8x+4y=48
-4y -4y
8x=48-4y
divide 8 to both sides

x=6-1/2y


substitute the given value of x into the equation 12x+5y=21

12(6-1/2y)+5y=21

distribute 12 through the parentheses

72-6y+5y=21

add like terms

72-y=21

move constant to the right hand side and change signs

-y=21-72

calculate the difference

-y= -51

change signs

y=51

solve the question for x

x= 6-1/2 x 51

x= -39/2

(x,y) = (-39/2 , 51)

So in each group of 5, we have one floral quilt square.

now, in 125 quilt squares, we want to find the number of groups of 5 that we can make with thos 125 quilt squares.

This is 125/5 = 15

So we have 15 groups of 5 quilt square.

And we know that in each of those groups, we have one floral quilt square.

So we have a total of 15*1 = 15 floral quilt squars.

Answer: 25

Step-by-step explanation: 125 quilt square in group of 5

125/5 = 25

Each group of 5 os 1 floral quilt so there are 25 floral quilts in total

a crew is setting up a zip line between two towers with support wires as shown in the figure (not to scale). they only know the heights of the towers and the angles that two of the supports make with the ground. what is the length of the zip line?

Answers

Answer:

length of the zip line = 121. 63 ft

Step-by-step explanation:

The length of the zip line AB forms a triangle  ABC. To find the length AB we need to know the length of 2 sides of the triangle an angle.

Triangle ADC

We need to find the hypotenuse side AC using the SOHCAHTOA principle.

Therefore,

sin 41° = opposite/hypotenuse

opposite = 65 ft

sin 41° = 65/AC

cross multiply

0.65605902899 AC = 65

divide both sides by 0.65605902899

AC = 65/0.65605902899

AC = 99.0764506359  ft

AC ≈ 99.08 ft

Triangle BCE

We are looking for side BC. The triangle BCE is also a right angle triangle so we use the same methodology like the triangle ADC.

sin 62° = opposite/hypotenuse

opposite = 85 ft

sin 62° = 85/BC

cross multiply

BC sin 62° = 85

BC = 85/sin 62°

BC = 85/0.88294759285

BC = 96.2684543086

BC ≈ 96.27 ft

The angle ACB can be gotten when you subtract 62° and 41° from 180 (angle on a straight line).

Therefore,

∠ACB = 180° - 62° - 41°

∠ACB  = 77°

Now let us use the cosine law to find the zip line AB.

c² = a² + b² - 2ab cos C

a = 96.27 ft

b = 99.08 ft

c² = 96.27² + 99.08² - 2 × 96.27 × 99.08 cos 77°

c² = 9267.9129 + 9816.8464 - 19076.8632 cos 77°  

c² = 19084.7593 - 19076.8632 × 0.22495105434

c²  = 19084.7593 - 4291.36049041

c² = 14793.398810

square root both sides

c = √14793.398810

c = 121.628116856

c ≈ 121. 63 ft

length of the zip line = 121. 63 ft
