The area of the four walls of a room is 156 m2. The breadth and height of the room are 8 m and 6 m
respectively. Find the length of the room.​

Answers

Answer 1
Given: Lateral Surface area=156m
Breadth=8m height=6m
⇒ L.S.A=2(bh+lh)=2(l+b)h
⇒156=2(l+8)h
⇒156=2(l+8)×6
⇒l+8=
12
156

=13
∴l=13−8=5m
Hence, length of the room=5m

A table is on sale for $289, which is 32% less than the regular price.
What is the regular price?

Answers

Answer:

[tex]R = \$903.125[/tex]

Step-by-step explanation:

Given

[tex]Selling\ Price = \$289[/tex]

[tex]Rate = 32\%[/tex]

Required

Determine the regular price (R)

From the question, we understand that:

[tex]R * 32\% = \$289[/tex]

So, we have:

[tex]R * 0.32 = \$289[/tex]

[tex]R = \frac{\$289}{0.32}[/tex]

[tex]R = \$903.125[/tex]

Hence, the regular price is $903.125

[tex]B2 = 0.465[/tex] --- Population standard deviation

[tex]C2 = 0.216[/tex] --- Population Variance

Step-by-step explanation:

Given: Wake-up time data

Required: Determine the population standard deviation and the population variance using Excel

First, enter the given data in Excel

For this question, I entered the data in cell A2 through cell A21

Cell B2 and Cell C2 were used to hold the results of the population standard deviation and the population variance, respectively.

In cell B2, the formula to use is:

=ROUNDUP(STDEV.P(A2:A21),3)

The round function rounds the result to 3 decimal places while STDEV.P calculates the population standard deviation.

So, the result is:

[tex]B2 = 0.465[/tex]

In cell C2, the formula to use is:

=ROUND(VAR.P(A2:A21),3)

The round function rounds the result to 3 decimal places while VAR.P calculates the population variance.

So, the result is:

[tex]C2 = 0.216[/tex]

a patient needs fluid and carbohydrates for nutrition. which fluids is the patient likely to be administered ​

Answers

Answer:

5% Dextrose

Step-by-step explanation:

Dextrose is primarily used as a carbohydrate for nutrition and as a source of fluid. Whereas Sodium chloride is primarily used as a source of fluid and electrolytes.

A patient needs fluid and carbohydrates for nutrition. The fluid that the patient is likely to be administered is TNP. The patient needs fluid and carbohydrates for nutrition. The correct option is b.

What is TNP?

Total parenteral nutrition (TPN) is a feeding technique that omits the digestive system. The majority of the body's nutritional requirements are met by a specific formula administered intravenously.

When a person cannot or shouldn't receive feedings or fluids orally, the technique is utilized. The term "parenteral nutrition," sometimes known as "total parenteral nutrition," refers to the practice of administering a unique type of food through a vein (intravenously).

The treatment's aim is to treat or stop malnutrition. TPN is made up of many components that are mixed together. These components include dextrose, lipid emulsions, amino acids, vitamins, electrolytes, minerals, and trace elements.

Therefore, the correct option is b, total parenteral nutrition.

please help me huhu​

Answers

Answer:

7.2 km

Step-by-step explanation:

Given that:

Hours taken = 2 hours

Walk rate = 1 m/s

Distance = Speed * time

Time taken in seconds = 2 * 60 * 60 = 7200 s

Hence,

Distance = 1 m/s * 7200s

Distance = 7200 meters

Distance in km = 7200 / 1000 = 7.2 km

If IM is reflected across the x-axis and then translated along the vector <4, 1>, in
which quadrant is the final image?

Answers

Answer:

Final image L"M" will lie in the fourth quadrant.

Step-by-step explanation:

Coordinates of the ends of segment LM,

L  → (-3, 4)

M → (-3, 2)

Rule to reflect a point across x-axis is,

(x, y) → (x, -y)

By this rule, coordinates of the image point of L and M will be,

L(-3, 4) → L'(-3, -4)

M(-3, 2) → M'(-3, -2)

Further these image points are translated along the vector <4, 1>

Rule for this translation will be,

(x, y) → (x + 4, y + 1)

Now the image points of the points L' and M' will be,

L'(-3, -4) → L"(-3 + 4, -4 + 1)

             → L"(1, -3)

M'(-3, -2) → M"(-3 + 4, -2 + 1)

              → M"(1, -1)

Therefore, final image L"M" will lie in the fourth quadrant.
