$175 (25*3=25) (25*5=125) (25*7=175)
Answer:
w=18
Step-by-step explanation:
You can use trig here - you want to know the angle opposite from the shortest side, which we'll call "A," and you have the sides that touch the right angle. side A (21 inches) and side B (25 inches) intersect at a right angle, so the side we're missing is the hypotenuse. the angle across from side A is angle "a" - now, since we know which side is the hypotenuse, we can figure out which trig function works here. angle "a" can be found by doing tan(a)=Opposite/Adjacent --> tan(a)=A/B --> tan(a)=21/25 --> a=tan^-1(21/25). a = 40.03 degrees
For the recipe calls for 34 teaspoon of salt in 1 cup of
water
The salt concentration of salt is (34/1) teaspoon per cup
= 34 teaspoon per cup
For the recipe that calls for 1 teaspoon of salt in 2 cups
of water
The salt concentration of salt is (1/2) teaspoon per cup
= 0.5 teaspoon per cup
The recipe with a higher salt concentration is the first one
(34 teaspoon of salt in 1 cup of water) and that will taste saltier than the
other recipe.
Coefficient because the number in front of the variable is the coefficient
