What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total candidates = 23+ 2 + 3 = 28

and, Each canoe can hold 3 people.

So, number of  canoes will they need

= 28/3

= 9.333

Hence, 10 canoes will they need.

They would need 10 Canoes. There is 28 people. Divide that by 3 and gives you a decimal of 9.33 repeating. Since you cant cut people up in half just round it up 

True or false:x/3 is equivalent to 1/3x.explain your reasoning.

Answers

Yes, both the expressions are equivalent.

What is an expression?

An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation. This maths operation can be addition, subtraction, multiplication, or division.

Given that, x/3 is equivalent to 1/3x, yes or not?

So, we can write x/3 as

1/3×x

= x/3

Since, either you multiply by 1/3 or divide by 3 both are same thing,

1/3×x = x/3 = 0.333x

for example; 4÷2 = 2 or 4×1/2 = 2, in both case the answer is same, that means the expression given are also equal.

Hence, we can conclude both the expressions are equivalent.

What is the volume of a cylinder with a radius of 7 feet and a height of 12 feet? Use 3.14 for pi. Round your answer to the nearest hundredth.A. 1,846.32 cubic feet
B. 1,950.25 cubic feet
C. 1,999.21 cubic feet
D. 2,000.31 cubic feet

Please answer asap

Answers

The volume of the cylinder to the nearest hundredth is  1,846.32 cubic feet.

A cylinder is a three-dimensional shape. It is a prism with circular edges.

Volume of a cylinder = πr²h

  • π = pi = 3.14
  • r = radius
  • h = height

3.14 x 7² x 12 = 1,846.32 cubic feet

Please find attached an image of a cylinder. To learn more about to determine the volume of a cylinder, check: brainly.com/question/12763699

Find the area of the base of the cylinder, 

A = \pi x 49

Then multiply by the height of the cylinder,

49\pi x 12 = 588\pi

then insert 3.14 for pi

588 x 3.14 = 1,846.32 cubic feet

Namel. In a science experiment, Judson is tracking theheight of a small tree. At the beginning the treemeasures 32 inches. Six weeks later the treemeasures 36 inches. Find the percent increase ofthe tree.

Answers

The percent increase in the height of tree after six week will be equal to

12.5%.

What is the Percentage?

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the information in the question,

The initial height of the tree = 32 inches

After six weeks the height of the tree = 36 inches

So, the percentage change will be,

% change = (36 - 32)/32 × 100

= 4/32 × 100

% change = 12.5%

To know more about Percentage:

#SPJ5

percent increase = (new measurement-old measurement)/(old measurement) *100= (36-32)/(32) *100= (4)/(32) *100= (100)/(8)=12.5%
