Answer:
12
Step-by-step explanation:
A rhombus is a parallelogram with all four sides equal.
Its diagonals are perpendicular.
Each of the triangles formed by the diagonals and the sides are congruent, so the area of the rhombus is 4 times the area of one of the triangles.
Since the short diagonal is given as 4, each of the triangles can be viewed as having a base of 2. Each triangle's height, h, then is one half the length of the long diagonal.
The are of one of the triangles is 1/2 (base)(height)=(1/2)(2)h
The area of the rhombus is then
4(1/2)(2)h=24
Solving for h gives
h=6
This makes the length of the long diagonal 2h=12
140 because 14 ten times is 140 and thats the same value as 14 tens
Answer:
The first 2
Step-by-step explanation:
First expression = -4+30-3 =23
Second expression = 8(10+4)= 112.
The others would lead to a negative number.
Remember negative times negative = positive
Negative times negative times negative = negative
I just helped my sister on this problem its kinda scary... :P
If you mean 1/3 and 3/5
Belinda has 135 beads in total.
Find 1/3 of 135.
135 ÷ 3 = 45.
Belinda uses 45 beads to make the bracelet.
Hope I helped :)
