A: 152 square inches
B: 212 square inches
C: 216 square inches
D: 232 square inches

Answers

Answer:

it's a 152

Step-by-step explanation:

The surface area of the rectangular prism is S = 232 inches²

What is the surface area of the prism?

The surface area of the prism is calculated as

The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism

Surface Area of the prism = 2B + ph

The area of the triangular prism is A = ph + ( 1/2 ) bh

Given data ,

A serving tray is in the shape of a rectangular prism without a top.

And , dimensions of the tray are 8 inches by 10 inches by 2 inches.

So , surface area A = 2(80) + 2(16) + 2(20)

A = 160 + 32 + 40

A = 232 square inches

Hence , the surface area is 232 inches²

What angle measure is complementary to a 65 angle?

Answers

Answer:

x = 25

Step-by-step explanation:

Complementary angles add to 90 degrees

x+65 = 90

Subtract 65 from each side

x = 90-65

x = 25

The Definition of Complementary Angles states that if two angles are

complementary, then the sum of their measures is 90°.

To find the complement of an angle, we take 90 degrees minus the

measure of the angle which in this case 90° - 65° or 25°.

So the complement of the 65° angle measures 25°.

1) A microbiologist measures the length of a bacterium of 0.000163 m and the

length of yeast as 0.0087 mm.

a) Which is longest? (Hint: Both must be the same units)

b) How much longer is the longer specimen than the shorter specimen?

Answers

Answer:

a) The bacterium is longer;

b) The bacterium is 0.1543 mm longer than the yeast.

Step-by-step explanation:

In order to compare the length of the two beings we need to convert them to the same unit. We can do it either way, but we'll choose to convert from meters to milimetres, since we're dealing with small numbers. To do that we need to multiply the length that is in "m" by 1000.

[tex]length_{bac} = 0.000163*1000 = 0.163 \text{ mm}[/tex]

a) The bacteria is longer than the yeast.

b) We need to subtract their length in order to find this answer:

[tex]\text{dif} = length_{bac} - length_{yeast}\\\text{dif} = 0.163 - 0.0087 = 0.1543 \text{ mm}[/tex]

Since we know U is the midpoint, we can say TU equals BLANK? Substituting in our values for each we get BLANK? =12x - 1

Answers

Answer:

x = 3

Length of each segment = 3

Step-by-step explanation:

Since point U is the midpoint of the line segment TV, that means both the parts of the segment UV and TU will be equal in measure.

m(TU) = m(VU)

(8x + 11) = (12x - 1)

By further solving this,

8x + 11 + 1 = 12x - 1 + 1

8x + 12 = 12x

8x + 12 - 8x = 12x - 8x

12 = 4x

x = [tex]\frac{12}{4}[/tex]

x = 3

(12x - 1) = 12×3 - 1

           = 35

And the length of each segment will be 35 units.

3 Euros can be exchanged for 22.41 Kroners. How many Euros can be exchanged for 100 Kroners?

Answers

the answer is 4.4 Euros

Answer:

13.39 Euros

Step-by-step explanation:

The ratio between Euros and Kroners is 3:22.41. This means for every 3 Euros we get 22.41 Kroners. This also means for every Euro we get 22.41/3 = 7.47 Kroners. To calculate the number of Euros that can be exchanged for 100 Kroners, we simply divide 100 Kroners by our conversion factor. 100/7.47 = 13.3868809

If y varies inversely as x2 and y = 3 when x = 2, find the equation that connects x and y.

Answers

Answer:  y = 12/(x^2)

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

Explanation:

"y varies inversely as x^2" means y = k/(x^2) for some constant k.

Plug in (x,y) = (2,3) and solve for k

y = k/(x^2)

3 = k/(2^2)

3 = k/4

3*4 = k

12 = k

k = 12

The original equation updates to y = 12/(x^2)

As a check, plugging in x = 2 should lead to y = 3

y = 12/(x^2)

y = 12/(2^2)

y = 12/4

y = 3 ... we get the proper y value, so the answer is confirmed.

The equation that connects x and y, is,   y = 12/(x^2).

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

"y varies inversely as x^2" means y = k/(x^2) for some constant k.

Plug in (x,y) = (2,3) and solve for k

y = k/(x^2)

3 = k/(2^2)

3 = k/4

3*4 = k

12 = k

k = 12

The original equation updates to y = 12/(x^2)

As a check, plugging in x = 2 should lead to y = 3

y = 12/(x^2)

y = 12/(2^2)

y = 12/4

y = 3 ... we get the proper y value,

Hence, The equation that connects x and y, is,   y = 12/(x^2).

What is displacement?

Displacement is defined as the minimum distance between two points. It is a vector quantity and needs direction with magnitude.

It is given that

Initial position =14.2 m

Final position=-2.3 m

14.2+(16.5)=-2.3

To understand this, we need to first calculate the displacement between his initial and final position

Displacement = Final pposition - Initial position

Displacement= -2.3-14.2

Displacement =-16.5 m

So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

Chen is bringing fruit and veggies to serve at an afternoon meeting. He spends a total of $28.70 on 5 pints of cut veggies and 7 pints of cut fruit. The food cost is modeled by the equation 5 v plus 7 f equals 28.70, where v represents the cost of one pint of cut veggies and f represents the cost of one pint of cut fruit. If the cost of each pint of fruit is $2.85, what is the approximate price of a pint of veggies? (Round to the nearest cent, as needed.

Answers

Answer:

one dollar 75 cents

Step-by-step explanation:

lets write the original equation again

5v+7f=28.70

now, lets put in the cost of the fruit to find cost of veggies

When the quantity of an inventory item falls below a pre-set minimum level, the warehouse manager sends an online inventory status report to production department advising them to schedule a production batch run for the item. Upon receipt of the report, the production clerk assesses the digital bill of materials and the route sheet files for the item to be produced and adds the production details to the online production schedule. The system automatically adds a record to the open work order file and sends an online work order to the work centre supervisors computer and to the accounting clerks computer. The work centre supervisor receives the work order from his computer and print hard-copy move tickets and materials requisitions for each production process. Production employees take the materials requisitions to store clerk and receives the materials and subassemblies needed to perform the production tasks. If additional materials beyond the standard amount is needed, the work centre supervisor prepares additional materials requisitions. Production employees complete job time tickets after completing a production process to record the time spent on the job. The job time tickets are then sent together with the move tickets to the accounting department. After releasing the materials into production, the store clerk updates the material inventory records and send the materials requisitions to accounting department. The clerk prepares a journal voucher and posts to the general ledger material control account at the end of each day. The accounting clerk assesses the work orders and set up a work-in-process account for a production batch. Throughout the production period, the clerk also receives move tickets, job tickets, and materials requisitions, which he uses to post to the work-in-process account.

MD: We have been through these types of projects before, and what always ends up happening is that we do not get the new system we are promised. Instead we get a modified version of the old system. CIO: I can assure you that will not happen this time. My team just want a thorough understanding of what is working well and what is not. MD: I would feel much more comfortable if we first started with a list of our requirements. We should spend more time in determining what exactly we want the system to do upfront. Then your team can come in and determine what portions to salvage if you wish. Just dont constrain us to the old system! Required: a) The CIO and MD have different views on how the system analysis should be performed. Comment on whose position you sympathise with the most.
