-50
Step-by-step explanation:
-12 + (-38) can also be written as -12-38, and that would be -50
If you continue the line of the second step (from the top), you will get a parallel to the floor which will also equal to 4 feet.
Now the right triangle just created has one leg = 4 feet and another = 3 feet.
Calculate the hypotenuse (Railing) using Pythagoras;
(Railing)² = 4² + 3²
((Railing)² = 4² + 3²
Railing)² = 16 + 9 =25
(Railing)² = 25 and Railing = √25 = 5
Answer:
a) 4/7 L = 0.57 L
b) 25/7 L = 3.57 L
Step-by-step explanation:
The ratio of orange juice to ginger ale is 2:5.
Add 2 + 5 = 7.
The ratio of orange juice to ginger ale to total drink is 2:5:7.
a) The fraction of orange juice is 2/7 of the total drink.
To make 2 L, you will need 2/7 of 2 L to be orange juice.
2/7 * 2 L = 4/7 L = 0.57 L
b) The fraction of ginger ale is 5/7 of the total drink.
5/7 * 5 L = 25/7 L = 3.57 L
Well put it in correct order : <span>4z-111+3z-12=300.
</span><span><span><span><span><span>4z</span>−111</span>+<span>3z</span></span>−12</span>=300</span>
<span><span><span><span><span>4z</span>−111</span>+<span>3z</span></span>−12</span>=300</span>
