Your grandmother is in the hospital and is put on a liquid diet. After examining her chart, a mistake is found stating that her weight is 650 kg. What is the equivalent weight in pounds and what is the most likely mistake?

Answers

650 kgs is equal to 1,433 lbs. I believe the mistake would be that they forgot to add a period in between 65 and the 0, because 65.0 kgs is equal to 143.3 lbs.

The width of a rectangle is 4 less than half the length. If represents the length, which equation could be used to find the width, w?

Answers

w = width
l= length

w = l/2 - 4

l/2 repreaents half the length
- 4 is 4 less than half the length

The equation of the width(w)  is  l/2-4.

What is the equation ?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

According to the question

length is represented by l

width is represented by w

so w=l/2-4.

Therefore, he equation of the width(w)  is  l/2-4.

A 1500 kg hippo is completely submerged, standing on the bottom of a lake. What is the approximate value of the upward normal force on the hippo?

Answers

Answer:

About 428 N

Step-by-step explanation:

Weight = 1,500 * 9.8 = 14,700 N

Density = Mass ÷ Volume

1,030 = 1,500 ÷ V

V = 1,500 ÷ 1,030  = 1.46 m^3.

Buoyant force = Density * g * V  

Buoyant force = 1,000 * 9.8 * (1,500 ÷ 1,030)

Buoyant force = 9,800 * (1,500 ÷ 1,030)  = 14,272 N.

Net force = 14,700 – [(9,800 * (1,500 ÷ 1,030)]

Final answer:

The upward normal force on a 1500 kg submerged hippo is approximately equal to its weight, calculated as its mass times the acceleration due to gravity (1500 kg × 9.81 m/s²), resulting in a force of 14715 N.

Explanation:

The question is asking about the upward normal force on a submerged hippo in a lake. To find this force, we must understand that the upward normal force that the ground (or in this case, the lake bed) exerts on the hippo is equal to the weight of the hippo, which is the product of the hippo's mass (m) and the acceleration due to gravity (g).

In equation form: Normal Force = m × g. Plugging in the values, we have a 1500 kg hippo and the acceleration due to gravity is approximately 9.81 m/s². Therefore, the upward normal force is:

Normal Force = 1500 kg × 9.81 m/s² = 14715 N.

This is the approximate value of the upward normal force exerted on the hippo standing on the bottom of the lake.

B. (2, 4), (0, 2), (2, -4), (5,3)
c. (1,6), (2, 7), (4, 9), (0,5)
D. (0,2), (2,3), (0, -2), (4,1)​

Answers

Answer:

Option C is correct.

Step-by-step explanation:

Function is a Relation from set A to Set B whose every element of set A has one and only one image  in Set B.

Option A).

(0,2) , (2,3) , (0,-2) , (4,1)

here 0 has two image 2 and -2.

So, this is not function.

Option B).

(1,2) , (1,-2) , (3,2) , (3,4)

here 1 has two image 2 and -2.

So, this is not function.

Option C).

(1,6) , (2,7) , (4,9) , (0,5)

Here every element has only one image.

So, this is a function.

Option D).

(2,4) , (0,2) , (2,-4) , (5,3)

here 2 has two image 4 and -4.

So, this is not function.

Therefore, Option C is correct.
