From the given triangles in the picture attached,
∠A ≅ ∠X [Given]
∠B ≅ ∠Y [Given]
By AA property of similarity of the triangles, both the triangles will be similar.
ΔABC ~ ΔXZY
Similarity statement:
Corresponding sides of these similar triangles will be proportional.
[tex]\frac{XZ}{AB}= \frac{ZY}{BC}=\frac{XY}{AC}[/tex]
Similarity ratio:
[tex]\frac{XY}{AC}=\frac{24}{16}[/tex]

3/4 + 3/9 how do i do this
Answer:
13/12
Step-by-step explanation:
Well, you can't add it yet because the denominators don't match. We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change as well. So, multiply 3 by 8, and get 24. Since 4 is evenly divided by 8, we can multiply just one term to get a common denominator. Multiply 3 by 2, and get 6, then we multiply 4 by 2 and get 8. Since our denominators match, we can add the numerators. So now your answer should be 9/8. Well guess what... IT IS THE ANSWER! You can't reduce it anymore so 9/8 is your answer! Hope this helped!

How many meals would be packed in 20 hours?
Given :
A graph of Total Meals Packed vs Time( in hours ).
To Find :
How many meals would be packed in 20 hours.
Solution :
First we will find the equation of line.
Now, the line passes through ( 0, 0 ) and ( 4, 500 ).
So, equation of line passing through ( 0, 0 ) and ( 4, 500 ) is :
[tex]y - 0 = \dfrac{500-0}{4-0}( x - 0 )\\\\y = 125x[/tex]
Now, putting the value of x = 20 hours in above equation, we get :
y = 125 × 20 meals
y = 2500 meals
Therefore, number of meals packed in 20 hours is 2500 meals.
Write in point-slope form an equation of the line that passes through the point (−2,4) with slope −12.
Answer:
y - 4 = -12(x + 2)

Answer:
1.902
the answer is
the thousandth place is where the x is
0.00x
next it says that with rounding its to 2.
1.9 is rounded to 2
it says that 2 is in the thousandth place.
0.002
put it all together and you have 1.902
Answer:
2.112
Step-by-step explanation:
1) The number ends in the thousandths place.
thousandths place = 3rd decimal place after the decimal point. (ex. 1.234, 4 is in the thousandths place)
2) 2 is the nearest one when rounding
Rounding rules: 5 or above goes to the next number up. Four and below goes down.
Since none of these numbers is 5 or above, we know a two has to be in the ones place (you are unable to round up without a 5 or above).
3) A 2 is in the thousandths place.
Again, thousandths place = 3rd decimal place after the decimal point.
2.112 (2 is in thousandths place)

What is the extraneous solution to the equation (sqrt 2p+1) +2sqrt p = 12
Op=-4
O p= -2
O p = 0
Op=4
Answer:
c
Step-by-step explanation:
The extraneous solution to the given equation √(2p+1) + 2√p = 1 is x = 4.
What is an extraneous solution of an equation?"An extraneous solution is a solution, such as that to an equation, that emerges from the process of solving the problem but is not a valid solution to the problem."
Given equation is:
√(2p+1) + 2√p = 1
⇒ √(2p+1) = 1 - 2√p
⇒ (√(2p+1))² = (1 - 2√p)²
⇒ (2p + 1) = 1 - 4√p + 4p
⇒ 2p + 1 - 1 - 4p = - 4√p
⇒ -2p = - 4√p
⇒ p = 2√p
⇒ p² = 4p
⇒ p² - 4p = 0
⇒ p(p - 4) = 0
⇒ p = 0, 4
Now, putting the values of 'p' in the given equation, we get:
√(2p+1) + 2√p
= √(2 × 4+1) + 2√4
= √9 + 4
= 3 + 4 (if we take the positive sign only)
= 7
Therefore, p = 4 doesn't satisfy the given equation.
Therefore, p = 4 is the extraneous solution to the equation.
