Answer:

5.5 gallons

Step-by-step explanation:

set up a proportion; Liters in numerator and Gallons in denominator

let x = approx number of gallons

<u> 21 </u> = <u> 3.8 </u>

x           1

3.8x = 21

x = 21 ÷ 3.8

x ≈ 5.5

Hi! Can someone help me please.
Sati [7]

Answer:

27 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2  where c is the hypotenuse

We are given the diagonal, which is the hypotenuse and a leg

36^2 + b^2 = 45^2

Subtract 36^2 from each side

36^2 + b^2 - 36^2 = 45^2 - 36^2

b^2 = 45^2 - 36^2

     b^2 =2025-1296

          b^2 =729

Take the square root of each side

sqrt(b^2) = sqrt(729)

b =27

Step-by-step explanation:

(- 10x² + 2) + (- 2x² + 9x + 7 ) ← remove parenthesis

= - 10x² + 2 - 2x² + 9x + 7 ← collect like terms

A father's age is 4 times as that of his son's age. in 5 years time, the father will be 3 times as old as his son. what are thei
Vadim26 [7]

Answer:

<h3>present age of son = 10 </h3><h3>present age of father = 40</h3>

Step-by-step explanation:

Let, present age of son be 'x'

present age of father be 'y'

y = 4x→ equation ( i )

After five years,

Son's age = x + 5

father's age = y + 5

According to Question,

y + 5 = 3(x + 5)

Put the value of y from equation ( i )

4x + 5 = 3(x + 5)

Distribute 3 through the parentheses

4x + 5 = 3x + 15

Move variable to L.H.S and change it's sign

Similarly, Move constant to R.H.S. and change its sign

4x - 3x = 15 - 5

Collect like terms

x = 15 - 5

Calculate the difference

x = 10

Now, put the value of X in equation ( i ) in order to find the present age of father

y = 4x

plug the value of X

= 4 \times 10

Calculate the product

= 40

Therefore,

Present age of son = 10

present age of father = 40

Hope this helps..

Best regards!!
