Answer: 78

Step-by-step explanation: multiply 44 by 2 because there are two sides on the rectangle and then you add 5 and 5 because yet again there are two sides so when you get your answer subtract 10 from the 88 and then you get 78 there is your explanation and equation

Rectangle with perimeter 44 ft has its length and breadth 13 ft and 9 ft respectively.

Dimension of rectangle : 13 × 9

Given, that perimeter of rectangle is 44 ft .

Now, perimeter of rectangle is given by:

P = 2(l + b)

l = Length of rectangle .

b = Breadth of rectangle.

Let the breadth of rectangle be 'x' m.

Then length will be (2x -5) ft.

Substitute the values in the perimeter formula,

[tex]44 = 2(x + 2x -5)\\22 = 3x -5\\x = 9[/tex]

Thus the breadth of rectangle is 9 ft .

Length of rectangle is 5 ft less than twice its breadth.

Length = 2(9) - 5

Length = 13 .

Therefore the dimensions of rectangle is 13 × 9.

Answer:

If 0.65 is a decimal, then as a fraction it would be 65/100. This can be simplified though. 65 and 100 are both divisble by 5.

100 divided by 5 is 20 and 65 divided by 5 is 13. This is as simplified as it can go, so the answer is 13/20.

Graham drove 32.58 miles in one hour and it took 1.84 minutes to drive a mile

Miles Graham drove in 13 hours = 423 miles

Unitary method: A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. It is a technique that we employ for the majority of math calculations.

Part a:

Miles driven in one hour = Total miles driven/Total no. of hours taken

= 423/13 = 32.58 miles

Part b:

Hours took to drive a mile = Total no. of hours taken/ Total miles driven

After solving the equation, x = 3/2 is the value of x in 2x = 3.

⇒ 2x = 3

⇒ x = 3/2

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

Answer: The decimal equivalent to 2/9 = 0.22

Step-by-step explanation:

Define Decimal equivalent :

The decimals with the same number of decimal places are called like decimals. Equivalent decimals are decimal numbers that have the same value. For example, 3.42, 6.05 are like decimals as they have two decimal places. For example, 0.3 and 0.30 are equivalent decimals as they present the same value.

How do you find the equivalent decimal?

To find the decimal equivalent of a fraction, divide the numerator by the denominator. Because the number in the numerator is smaller than the number in the denominator, you have to place the decimal point after it and add zeros. Then complete long division.

Given data,

Find the decimal equivalent to 2/9.

To get a fraction into a decimal you have to divide the fraction. I was taught since the 2 is the numerator, it gets divided out of and the 9 is what you're dividing the 2.

so, we can write,

                        x = 2/9

where,          numerator = 2

                     denominator = 9

Then, x = 2/9 = 0.22

Therefor, the decimal equivalent to 2/9 = 0.22

If Colton is 1.55 meters tall. At 1 p.m., he measures the length of a tree's shadow to be 44.35 meters. the height of the tree to the nearest hundredth of a meter. is 12.85 meters.

First step is to find the distance that he is horizontally from the top of the shadow

Distance = 44.35 meters - 39 meters

Distance = 5.35 meters

Second step is to make use of equal proportion and find the height

5.35/ 1.55 = 44.35/x

5.35x = 1.55 × 44.35

x=  1.55 × 44.35 /5.35

x= 12.849

x= 12.85 meters (Approximately)

Therefore If Colton is 1.55 meters tall. At 1 p.m., he measures the length of a tree's shadow to be 44.35 meters. the height of the tree to the nearest hundredth of a meter. is 12.85 meters.

Step-by-step explanation:

You can just simply find this answer using a calculator.

The amount after 10 years is $11,842.43

In continuous compounding the number of times by which compounding occurs tends to infinity.

In order to calculate the amount use the following formula

A= Pe^rt

where P represents the initial amount, e is the mathematical constant having value 2.7182, r is the rate of interest and t is the time period

Here the principal amount is $6000, r is 6.8 and time period t is 10 years

A = $6000 x 2.718⁽¹⁰ ˣ ⁶·⁸ %⁾

A = 6000 x 2.718⁽¹⁰ ˣ ⁶·⁸÷¹⁰⁰⁾  

A = 6000 x 2.718 x 0.68

A = $ 11,842.43

Answer:20

Step-by-step explanation:

The respective prices are given below as

The price of the sandwich is 20/3 dollars.

The salad may be purchased for a price of $16/3.

There is a fee of $2 for the drinks.

Let's say that the price of the sandwich is x.

Allow the price of salad to equal y.

Allow the price of drinks to equal z.

The new total for this meal is $46. It includes three sandwiches, three beers, and two salads. Thus;

3x + 3y + 2z = 40 ——- (eq 1)

The price of $29 covers two sandwiches, two drinks, and one salad.

Thus;

2x + 2y + z = 26 ——-(eq 2)

It will cost you $54 for four sandwiches, one drinks, and three salads. Thus;

4x + y + 3z = 38 ———-(eq 3)

The following are the results of concurrently solving the three equations:

x = 20/3

y = 16/3

z = 2

Therefore, the following is how much each item costs:
