6 peaches were there in each box
Solution:
18/3 = 8
Perimeter of a poligon= sum of all sides.
Perimeter of this triangle=s+(s+4)+3s=5s+4
An expression that represents the perimeter of this triangle is: 5s+4
The inspector can expect to find 450 units in a batch of 3000 phones
Step-by-step explanation:
Given
Total Cellular Phones = S = 60
Defective phones = E = 9
We will calculate the probability of defective forms first
So,
The probability of defective phones in 60 phones is 0.15
Now,
Total phones = 3000
The inspector can expect to find 450 units in a batch of 3000 phones

Answer:
Step-by-step explanation:
Using quadratic formula
we will have two solutions.
2x^2 - x - 4 = 0
So, a=2 b=-1 c=-4, we have:
Finally, we have two solutions:
1. Answer – Always
The diagonals of a rhombus are always perpendicular. In fact, if the diagonals of a parallelogram are perpendicular bisectors of each other, then it must be a rhombus. In addition to this, a rhombus always has all four congruent sides.
2. Answer – Always
The diagonals of a rectangle are always congruent (i.e. they are equal in length). Furthermore, in every rectangle, the diagonals bisect each other. Because the diagonals are equal in length, each diagonal divides the rectangle into two congruent right triangles.
3. Answer – Never
The diagonals of a trapezoid are never perpendicular; the diagonals are only perpendicular in rhombuses and squares. In a trapezoid however, the diagonals are congruent. A trapezoid is a quadrilateral that has only one pair of parallel sides.
