Answer:
I also belive for Part A the second one is the answer because it equals 120 Part B is 120 pints! Good Luck! And I hope this Helps!
To find the width of the scale drawing of the toddler room, you can set up a proportion/ratio.
2.5 m/4 m= 5 cm/x cm
To get from 2.5 to 5, you multiplied by 2, so you will do the same thing to 4 to find the missing scale width.
4 x 2 = 8 cm
The width of the scale drawing is 8 cm.
Answer:
No. Hank wont be able to complete the hike.
Step-by-step explanation:
Time Available for hike = 4 hours
The expression which represents the time Hank needs to complete the hike is:
d is the distance in miles of the hiking trail. Since, Hank would like to hike 6 miles, d = 6
e is the elevation gain in thousands. Since, the trail hank will hike on has an elevation gain of 3000, so e = 3
Using these values in the expression, we get:
This means Hank should allow him 4.5 hours or the hike. Since he has only 4 hours available, he wont be able to complete the hike. So the answer to this question is No.
Step-by-step explanation:
#1.
(a + 2b)²
<em>Using identity (x + y)² = x² + 2xy + y², we get:</em>
= (a)² + (2b)² + 2 × (a) × (2b)
= a² + 4b² + 4ab
= a² + 4ab + 4b² Ans.
#2.
(5x - 3y)²
<em>Using identity (a - b)² = a² - 2ab + b², we get:</em>
= (5x)² + (3y)² - 2 × (5x) × (3y)
= 25x² + 9y² - 30xy
= 25x² - 30xy + 9y² Ans.
#3.
(3a + 4)(3a - 4)(9a² + 16)
<em>Using identity (x + y)(x - y) = x² - y², we get:</em>
= [(3a)² - (4)²][9a² + 16]
= (9a² - 16)(9a² + 16)
= (9a²)² - (16)²
= 81a⁴ - 256 Ans.
