Ok see for doing percentage it is very easy just divide it by the main number I mean see if there is a food price 10 dollars and it has 20%off then u divide 20/10x100 u divide it by the actual number and then multiply it by 100 so the answer of my 20/10x100 is 10x20/100 ok so the answer is 2. The price is 2
Answer:
84 minutes
Step-by-step explanation:
7 people paint 5 walls in =60 minutes
=>1 people paint 1 walls in = (60X7)/ 5 minutes
=>10 people paint 10 walls in = (60X7X10)/(5X10) minutes =84 minutes
Answer:
Circle C1 can be dilated at its center by a scale factor of 1/2. Then the image can be translated left 4 and down 6. This will map circle C1 onto circle C2 and prove they are similar.

<u>Answer:</u>
![x = 23.6](https://tex.z-dn.net/?f=x%20%3D%2023.6)
<u>Step-by-step explanation:</u>
To find the missing side of a right-angled triangle, first look at the given angle, and notice its relationships with the given and required sides.
In this case:
• The side adjacent to the given 38° angle is
(required).
• The hypotenuse is 30 units.
The trigonometric ratio that relates the adjacent side and hypotenuse of a triangle is cosine (cos), where:
.
Substituting into the formula:
![cos (38^{\circ}) = \frac{x}{30}](https://tex.z-dn.net/?f=cos%20%2838%5E%7B%5Ccirc%7D%29%20%3D%20%5Cfrac%7Bx%7D%7B30%7D)
⇒ ![x = cos(38^{\circ}) \times 30](https://tex.z-dn.net/?f=x%20%3D%20cos%2838%5E%7B%5Ccirc%7D%29%20%5Ctimes%2030)
⇒ ![x = 23.6](https://tex.z-dn.net/?f=x%20%3D%2023.6)
