4 √(40) + 7 √(160)
​

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

44√(40) + 7 √(160) = 4√(2*2*2*5)  + 7√(4*4*5*2)\n  = 4*2√(10)  + 7*4√(10)\n = 8√(10) + 28√(10) \n

= (8 + 28)√10

= 36√10
Answer 2
Answer:

Answer:

36√(10)

Step-by-step explanation:

Using the rule of radicals

√(a) × √(b) ⇔ √(ab)

Simplifying the radicals in the expression

√(40)

= √(4(10))

= √(4) × √(10) = 2√(10)

√(160)

= √(16(10))

= √(16) × √(10) = 4√(10)

Thus

4√(40) + 7√(160)

= 4 × 2√(10) + 7 × 4√(10)

= 8√(10) + 28√(10)

= 36√(10)

2552 miles
5.5 hours

2552miles/5.5hours=464 miles per hour

Answer=464 miles per hour
since you want to get mph, you divide:
2552 ÷ 5.5 = 464
The speed of the airplane is 464 miles per hour.

What is the quotient of 5.4 and -0.3

Answers

Hey there!

The "quotient" is basically the result of a division equation

Remember: \n -,- = + \n +,+ = + \n-,+ = - \n +,- = -

This pair is: +, - (Positive (+), negative (-)

So, this means your result will be a negative

(5.4)/(-0.3) = -18 \n \n (-0.3)(-18) = 54 \n -18 = -18

Therefore your quotient is -18

Good luck on your assignment and enjoy your day!

Hello!

If you divide or multiply by one negative number, the number will remain negative. Let's just divide 5.4 and 0.3, and add a negative after.

5.4/0.3=18

We add our negative

-18

Therefore, our quotient is -18.

I hope this helps!

the area of a rectangular patio is 5 5/8 square yards, and its length is 1 1/2 yards. what is the patio's width, in yards?

Answers

The formula for area of a rectangle is length times width.

A = L x W

5 5/8 = 4.5  x W

Hint: 1/2 yard = 3 feet divided by 2 = 1 1//2 feet

5 5/8 divided by 4.5 = 4.5 x W divided by 4.5

5 5/8 divided by 4.5 = W

Now, convert both fractions to eights, and divide.
