Answer:
15 ml
Step-by-step explanation:
If we mix 1 part concentrate and 5 parts water, we have 6 parts in total.
To create 90ml medicine, <em>how many "6 parts" are there?</em>
There would be 90/6 = 15 total "6 parts".
Each of the "6 parts's" 1 part is concentrate, so concentrate would be 1 * 15 = 15 ml.
<u>In ratio:</u>
![\frac{Concentrate}{Total(Water+Concentrate)}=\frac{1}{5+1}=\frac{1}{6}\\\frac{1}{6}*90=15](https://tex.z-dn.net/?f=%5Cfrac%7BConcentrate%7D%7BTotal%28Water%2BConcentrate%29%7D%3D%5Cfrac%7B1%7D%7B5%2B1%7D%3D%5Cfrac%7B1%7D%7B6%7D%5C%5C%5Cfrac%7B1%7D%7B6%7D%2A90%3D15)
Answer:
<u>a</u>
Step-by-step explanation:
Given :
⇒ P (Sumit) = 1/2
⇒ P (Sujan) = 1/3
⇒ P (Rakesh) = 1/a
⇒ P (total) = 3/4
============================================================
Solving :
⇒ 1/2 × 1/3 × 1/a = 3/4
⇒ 1/6 × 1/a = 3/4
⇒ 2/12 × 1/a = 9/12
⇒ a = <u>9/2</u>
Answer:
The coordinates of D is (-4,-9)
Step-by-step explanation:
Given
C = (2,7)
<em>M=(-1,-1) ----- Missing part of question</em>
Required
Determine the coordinates of D
<em>Let the coordinates of D be (x₂,y₂)</em>
<em>We'll solve this question using mid point formula;</em>
<em></em>
<em></em>
<em>Where</em>
and ![M(x,y) = (-1,-1)](https://tex.z-dn.net/?f=M%28x%2Cy%29%20%3D%20%28-1%2C-1%29)
Put these values in the formula
![(-1,-1) = (\frac{2+x_2}{2},\frac{7+y_2}{2})](https://tex.z-dn.net/?f=%28-1%2C-1%29%20%3D%20%28%5Cfrac%7B2%2Bx_2%7D%7B2%7D%2C%5Cfrac%7B7%2By_2%7D%7B2%7D%29)
By comparison;
and ![-1 = \frac{7+y_2}{2}](https://tex.z-dn.net/?f=-1%20%3D%20%5Cfrac%7B7%2By_2%7D%7B2%7D)
![-1 = \frac{2+x_2}{2}](https://tex.z-dn.net/?f=-1%20%3D%20%5Cfrac%7B2%2Bx_2%7D%7B2%7D)
Multiply both sides by 2
![-2 = 2 + x_2](https://tex.z-dn.net/?f=-2%20%3D%202%20%2B%20x_2)
Subtract 2 from both sides
![-2 -2 = x_2](https://tex.z-dn.net/?f=-2%20-2%20%3D%20x_2)
![x_2 = -4](https://tex.z-dn.net/?f=x_2%20%3D%20-4)
![-1 = \frac{7+y_2}{2}](https://tex.z-dn.net/?f=-1%20%3D%20%5Cfrac%7B7%2By_2%7D%7B2%7D)
Multiply both sides by 2
![-2 = 7 + y_2](https://tex.z-dn.net/?f=-2%20%3D%207%20%2B%20y_2)
Subtract 7 from both sides
![-2 - 7 = y_2](https://tex.z-dn.net/?f=-2%20-%207%20%3D%20y_2)
![y_2 = -9](https://tex.z-dn.net/?f=y_2%20%3D%20-9)
<em>Hence, the coordinates of D is (-4,-9)</em>
