Answer:
- 3 ornaments of each color
Step-by-step explanation:
There are 3 colors.
For each of the colors, the other two colors have 6 ornaments, hence we can determine that there are 3 ornaments of each color.
Answer:
No such triangle can exist. Any of the described relations may be in error.
Step-by-step explanation:
Taken at face value, the sum of the lengths of the sides is ...
x + x + (3x-10) = 5
5x = 15
x = 3
so the third side is 3·3 -10 = -1 in length. No such triangle can exist.
If one side is actually 3x-10, the perimeter must be greater than 6 2/3 and less than 40.
If the perimeter is actually 5, then the third side must be 3x-7.5 or an expression with an even smaller constant.
So, the mistake could be in copying any of the numbers, or in copying the multiplier in the description of the 3rd side. There is insufficient information to tell exactly what the mistake is.
The length of a median is equal to half the square root of the difference of twice the sum of the squares of the two sides of the triangle that include the vertex the mediam is drawn from and the square of the side of the triangle the median is drawn to.
triangle sides by a, b, c.
ma=122c2+2b2−a2
mb=122c2+2a2−b2
mc=122a2+2b2−c2
Given :
Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.
To Find :
The number of packages of erasers and pencils that were sold
.
Solution :
Let, number of erasers are x and pencils are y.
So, x + y = 220 ....1
Also, 2x + 5y = 695 ....2
Solving equation 1 and 2, we get :
x = 220 - 85 = 135
Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.
Hence, this is the required solution.
