A family has a monthly budget of $2,400. How much money is spent on each category? 44% is spent on housing. 23% is spent on food
Lunna [17]

Answer:

  • housing, $1056
  • food, $552
  • transportation, $408
  • savings, $240
  • clothing, $144

Step-by-step explanation:

Multiply the budget total by the percentage for each category:

  • housing: 44% × $2400 = $1056
  • food: 23% × $2400 = $552
  • clothing: 6% × $2400 = $144
  • transportation: 17% × $2400 = $408
  • savings: 10% × $2400 = $240

__

Find "the rest" by subtracting the total of percentages from 100%, or by subtracting the total of budget categories from $2400. Here, everything (not including savings) adds to 90% × $2400 = $2160, so the amount to savings is 10%, or $240.

Ishaan is 2 times as old as Christopher. 35 years ago, ishaan was 7 times as old as Christopher
Natalija [7]

Answer:The present age of both of them are Christopher = 42 years, and Ishaan = 84 years.

Step-by-step explanation: Solution:

Let present age of:

Christopher =  

x

yrs

Ishaan =  

2

x

yrs ( given that Ishaan is 2 times as old as Christopher)

35 yrs ago:

Age of Christopher = (

x

- 35)yrs

Age of Ishaan = (

2

x

- 35) yrs

According to question, 35 yrs back, Ishaan was 7 times older than Christopher.

Therefore

7 X (

x

- 35) = (

2

x

- 35)

7

x

- 245 =  

2

x

- 35

7

x

-  

2

x

= 245 - 35

5

x

= 210

x

= 42

So present age of Christopher =  

x

= 42 yrs

&

Present age of Ishaan =  

2

x

= 84 yrs

Check your solution:

As 84 is 2 times of 42 so Ishaan is 2 times older than Christopher.

35 yrs ago, Christopher was (42 - 35) = 7 yrs old and Ishaan was (84 - 35) = 49 yrs old so Ishaan was 7 times older than Christopher then.

Can yall help my friend plzz
GarryVolchara [31]

Step-by-step explanation:

The Pythagorean theorem used in right-angled (equilateral) triangles is a relationship between the sides of a right-angled triangle, where the sum of the square of the legs is equal to the square of the hypotenuse.

If a and b are legs, and c is the hypotenuse, then a2 + b2 = c2.

Because the triangle is right angled, there is no greater side length in the triangle, so an unlimited number of Pythagorean positions can be produced by flipping the sides.
