Your image attached has not sufficient criteria for Brainly users to answer. We will assume for now that you are asking what the line is equal to. This question will be deleted eventually due to Brainly ToS most likely
We note that this line is not linear, or squared. This means it might be cubical.
If it is cubical the line must be a variant of
f(x)=
.
However f(x)=
points the opposite direction so we must make it negative.
We also noticed we had to stretch it, so we had to add a fraction.
Your answer is f(x)=![-\frac{1}{8} x^{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B8%7D%20x%5E%7B3%7D)
<h2>○=> <u>Correct answer</u> :</h2>
of the drink is fruit juice
<h3>○=> <u>Steps to derive correct answer</u> :</h3>
Quantity of water in a drink = 650 ml
Quantity of fruit juice in a drink = 150 ml
Total quantity of both items in the drink :
![=\tt 650 + 150](https://tex.z-dn.net/?f=%20%3D%5Ctt%20650%20%2B%20150)
![\color{plum}=\tt 800 \: ml](https://tex.z-dn.net/?f=%20%5Ccolor%7Bplum%7D%3D%5Ctt%20800%20%5C%3A%20ml)
Thus, the total quantity of both items in the drink = 800 ml
Let the percentage of of fruit juice in the drink be x%.
Which means :
![= \tt\frac{x}{100} \times 800 = 150](https://tex.z-dn.net/?f=%20%3D%20%20%5Ctt%5Cfrac%7Bx%7D%7B100%7D%20%20%5Ctimes%20800%20%3D%20150)
![= \tt \frac{x \times 800}{100} = 150](https://tex.z-dn.net/?f=%20%3D%20%5Ctt%20%5Cfrac%7Bx%20%5Ctimes%20800%7D%7B100%7D%20%20%3D%20150)
![=\tt \frac{800x}{100} = 150](https://tex.z-dn.net/?f=%20%3D%5Ctt%20%20%5Cfrac%7B800x%7D%7B100%7D%20%20%3D%20150)
![=\tt 8x = 150](https://tex.z-dn.net/?f=%20%3D%5Ctt%208x%20%3D%20150)
![=\tt x = \frac{150}{8}](https://tex.z-dn.net/?f=%20%3D%5Ctt%20x%20%3D%20%20%5Cfrac%7B150%7D%7B8%7D%20)
![\hookrightarrow\color{plum} \bold{x = 18.75\%}](https://tex.z-dn.net/?f=%5Chookrightarrow%5Ccolor%7Bplum%7D%20%5Cbold%7Bx%20%3D%2018.75%5C%25%7D)
Then, the percentage of water in the drink :
![= \tt100 - 18.75](https://tex.z-dn.net/?f=%20%3D%20%5Ctt100%20-%2018.75)
![\color{plum}= \tt81.25\%](https://tex.z-dn.net/?f=%20%5Ccolor%7Bplum%7D%3D%20%5Ctt81.25%5C%25)
Thus, the percentage of water in the drink = 81.25%
<h3>○=> <u>Therefore</u> :</h3>
▪︎Percentage of fruit juice in the drink = 18.75%
▪︎Percentage of water in the drink = 81.75%
Answer:
x = -30
Step-by-step explanation:
g(x)= -2/3x+5
Let g(x) = 25
25= -2/3x+5
Subtract 5 from each side
25-5= -2/3x+5-5
20 = -2/3x
Multiply each side by -3/2
-3/2 * 20 = -3/2 * -2/3 x
-30 = x
Answer:
234 times
Step-by-step explanation:
<u>Number of times the number 7 appears in a hundred</u>
7 as units digit (07-17-27 ..... 97): 10 times
7 as tens digit (70-71-72..... 79): 10 times
20 times the digit 7 appears in first one hundred (0-100)
Let's calculate how many times 7 would be as units or tens in 7 hundreds
20X7 = 140 times digit 7 appears until number 699
<u>Now, from 700 to 777</u>
7 as hundreds digit (700-701-702 .... 777): 78 times
7 as tens digit (770-771-772 .... 777): 8 times
7 as units digit (707-717-727....777): 8 times
78 + 8 + 8 = 94 times the digit 7 appears in the range 700 - 777. Plus 140 times
140 + 94 = 234 times
The <em><u>correct answer</u></em> is:
SAS
Explanation:
In the diagram, we have that CE and ED are congruent.
We also know that ∠FEC≅∠FED; this is because these two angles form a linear pair. A linear pair has a sum of 180°; since m∠FED = 90°, this means that m∠FEC = 180-90 = 90°, and the two angles are congruent.
We also know that FE = FE, due to the reflexive property.
This gives us two sides and the angle between them, or SAS.
