Pamela is 9 years younger than Jiri and the sum of their ages is 41 what is jiri's age

Answers

Answer 1

Answer:

Jiri is 25 years old.

Step-by-step explanation:

1)Pamela =Jiri-9 ( Pamela is 9 years younger than Jiri)

2)Pamela +Jiri=41

Substitute equation 1 into equation 2

(J-9)+J= 41

2J-9=41

Add 9 to both sides:

2J=41+9

Divide by 2:

2J=50

J=25

Answer 2

the required Jiri's age is 25 years.

Pamela is 9 years younger than Jiri and the sum of their ages is 41. What is Jiri's age is to be determined.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

Let the age of Pamela and Jiri is x and y respectively
Pamela is 9 years younger than Jiri. so,
y = x + 9 - - - - (1)
the sum of their ages is 41
x + y = 41 - - - - (2)

From equation 1 put y in equation 2
x + x + 9 = 41
2x + 9 = 41
2x = 41 - 9
2x = 32
x = 32/2
x = 16
Now put this x =16 in equation 1
y = 16 + 9
y = 25

Thus, the required Jiri age is 25 years

The solution of the given equation is x = 2 and y = 8.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The value of x and y will be calculated as,

4x + 5(3x+2) = 48

4x + 15x + 10 = 48

19x + 10 = 48

19x = 38

x = 2

Calculate the value of y,

y = 3x + 2

y = 3(2) + 2

y = 6 + 2

y = 8

Therefore, the solution of the given equation is x = 2 and y = 8.

A piece of paper has an area of 93.5 square inches. How many times does it need to be folded in half before the area is less than 1 square inch? Explain how you know.

Answers

Answer:

7 times.

Step-by-step explanation:

Keep dividing 93.5 by 2 until it becomes less than 1.

The sheet needs to be folded in half 7 times.

Since the area of the piece of paper is 93.5 square inches, and we need to fold the sheet in half it 'n' times to get an area less than 1 square inch. This is written mathematically as 93.5(1/2)ⁿ ≤ 1.

So, dividing through by 93.5, we have

(1/2)ⁿ ≤ 1/93.5

(1/2)ⁿ ≤ 0.0107

taking natural logarithm of both sides, we have

㏑(1/2)ⁿ ≤ ㏑0.0107

n㏑(1/2) ≤ ㏑(0.0107)

n ≤ ㏑(0.0107)/㏑(1/2)

n ≤ -4.538/-0.693

n ≤ 6.55

Rounding up to the nearest whole number,

n ≅ 7

So, the sheet needs to be folded in half 7 times.

Cranberry juice is made with a 16:3:1 ratio of water:sugar:cranberries. How much water,

in gallons, how much water is needed in order to make three gallons of cranberry juice? Express your answer as a

common fraction.

Answers

4 1/2 cups of water

Answer:

2 2/5

Step-by-step explanation:

We need to find out how many gallons of water so,

16/20 = water

3 gallons * 16/20 = 48/20 = 2 8/20 = 2 2/5

this works because then cranberries would be:

2 2/5/16 = 15/100

and for sugar that means

15/100 * 3 = 45/100

so in total

2 40/100 + 45/100 + 15/100 = 3 gallons

and if we simpilfy 2 40/200 we get 2 2/5
