Answer:
80°
Step-by-step explanation:
Since a triangle has three angles that add up to 180°, you add the two given angles and subtract it from 180°.
1
70° + 30° = 100°
2
180° - 100° = 80°
Add five to both sides
-3x = 21
Divide by -3 on both sides
x = -7

They need to put 14.4 grams of onion powder in each bottle.
Given,
The quantity of onion powder in a seasoning blend = 4%
We have to find the quantity of pure onion powder should they include in a 72g bottle to make the final blend have 20% onion powder;
How much is a percentage?
A percentage is a certain number or part in every hundred. It is a fraction with the denominator 100, and the symbol for it is "%."
Here,
Let x be the seasoning blend.
Now, 4% of 72=20% of x
⇒ 0.04×72=0.2×x
⇒ 0.2x=2.88
⇒ x=2.88/0.2
⇒ x=14.4 g
Therefore, a container should contain 14.4 grams of onion powder.
