Answer:
32/12
Step-by-step explanation:
To calculate the tangent you need to divide the opposite side by the adjacent side: 70/24=35/12
Answer:
The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15% hydrochloric acid solutions is 18 ounces
Step-by-step explanation:
Given as :
Let The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15%
hydrochloric acid = x ounces
So, Total quantity becomes = ( x + 12 ) ounces
<u>Now, According to question</u>
x × 40% + 12 × 15% = (x + 12) × 30%
Or, x × + 12 × = (x + 12) ×
Or, 40 x + 12 × 15 = (x + 12) × 30
Or, 40 x + 180 = 30 x + 360
Or, 40 x - 30 x = 360 - 180
Or, 10 x = 180
∴ x =
i.e x = 18 ounces
So, The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15% hydrochloric acid solutions = x = 18 ounces
Hence, The quantity of 40% hydrochloric acid mixed with 12 ounces of a 15% hydrochloric acid solutions is 18 ounces . Answer
Answer:
third side = 6
using pythagoras theorem:
a² + b² = c²
Answer:
D
Step-by-step explanation:
a² - b² ← is a difference of squares and is factored in general as
(a + b)(a - b)
42² - 38² ← is a difference of squares and factors as
42² - 38² = (42 + 38)(42 - 38) = 80(4) = 320 → D
The correct statement is the first figure, that is:
To prove this, we need to solve each side of the inequality and see that, in fact, the term on the left side is greater than the term on the right. So:
As you can see 0.0038728 is less than 3343.4728, so this is the only answer that is true. The rest of the choices are false! Recall that Inequality tells us about the relative size of two values. Inequality refers the term greater or less than (this may include or not the equality)
