Answer:

To find the base of a triangle you would multiply the base and height then divide it by 2 so the base is 49 sm and since the height is twice that the height is 98 so then you would do 49 times 98 and thats 4,802‬ then you would divide that by 2 so 4802/2 is 2401 so the area of the triangle is 2401 sm

Gemiola [76]

Answer:

Yes, they are similar by SSS.

Step-by-step explanation:

You can see that the triangles have proportional sides. 12/8 = 1.5, 7.5/5 = 1.5. Since the sides have the same ratios, these triangles are similar!

Orange juice is a common breakfast drink that contains citric acid. If the hydronium ion concentration is 3.4 × 10-4 in orange j

Lelu [443]

Answer:

3.5

Step-by-step explanation:

Given : the hydronium ion concentration is $3.4*10^{-4}$ in orange juice

To Find: what is the pH?

Solution :

Definition of pH : pH is the negative log of the molar hydrogen ion concentration

Formula of pH : - log [H+]

Since we are given H+ = $3.4*10^{-4}$

So, substituting this value in formula :

$pH = - log [3.4*10^{-4}]$

$pH = - log [3.4*0.0001]$

$pH = - log [0.00034]$

$pH = 3.468$

pH = 3.468≈3.5

Thus the pH is 3.5

There are 4 pieces of paper, numbered 10 to 13, in a hat. After another numbered piece of paper is added, the probability of pic

yKpoI14uk [10]

Answer: The fifth piece of paper could have any number 9 and less or 14 and greater.

Step-by-step explanation: The list of choices is not given in the question, but it makes sense that the new number would not be a duplicate of any of the numbers 10, 11, 12, 13. Otherwise that would change the probability to 5/5.

So any other number could be a possibility.
