Two sandwiches divide by three brothers is:
2/3
So each brother gets two thirds of a sandwich.
X = Juan's age
y = Eliza's age
Some key words/phrases we can use to help us make the equation are:
-is (whatever comes after this word usually equals the end result, or what it equals)
-two years younger
-than
-half her brother's age
.
just break it down :)
x/2 (half her brother's age) - 2 (two years younger) = y (Eliza is...)
| basically,
v
x/2 - 2 = y
So if Juan is 6, then we need to plug in 6 for x.
6/2 - 2 = y
3 - 2 = y
1 = y
ANSWER: Eliza is one year old.
Answer:
AD ≅ CD.
Step-by-step explanation:
Statement : consider triangles ADB and DBC.
1) AB = CD
2) ∠ABD = ∠DBC
3) DB = DB
4) ⇒ ΔADB and ΔDBC are congruent triangles.
5) AD = DC.
Reasons ;
1) given, AB = CB
2) given, DB bisects ∠ ABC
3) common side of both triangles
4) as two sides and one angle are equal in both triangles
5) congruent triangles
Answer:
12cm
Step-by-step explanation:
The scoop of Ice Cream is in the shape of a circular solid which is a Sphere.
For the ice cream to fit into the cone, the volume of the cone must be equal to that of the sphere.
Radius of the Sphere=3cm
Volume of a Sphere =
Volume of a Cone=
The Cone of same radius must be 12cm tall.

Step-by-step explanation:
- It is algebraically defined (that is, there is an equation you can use to calculate its value).
The mean is the average of our numbers, it is easy to calculate. The formule we use to calcule the mean is:
mean =
Where N is the number of values we have in our sample.
(We divide the sum of our values by the number of data we have in our sample).
- It is easily influenced by extreme scores.
If we have extreme scores in our sample our mean could be affected by them. To avoid this we can adjust our sample. We can do this by eliminate the values that are in the extreme of our ordened data (we can just avoid the 10% of the largest data and the 10% of the smallest data in our sample) the mean of the rest of the data we have is the adjusted mean.
