Answer: It's hard to explain without a grid...

The grid method is a written method used to teach children multiplication. It involves partitioning numbers into tens and units before they are multiplied. In some schools the grid method is referred to as the box method of multiplication because children learn to partition numbers into a grid of boxes.

4 “3” Cards in a Deck

52/2=26 Red Cards in a Deck

2/4 “3” Cards in a Deck are red so it would be 26-2=24 I think

In the diagram, VZ/YZ=WZ/XZ. To prove that △VWZ ~ △YXZ by the SAS similarity theorem, which other sides or angles should be used

Vitek1552 [10]

Answer:

The angles $\angle VZW\cong \angle YZX$ are used to prove the similarity of triangles VWZ and YXZ.

Step-by-step explanation:

Given information: $\frac{VZ}{YZ}=\frac{WZ}{XZ}$

Two triangles are called congruent if their corresponding sides are in same proportion or the corresponding angles are same.

If two corresponding sides of triangle have same proportion and their inclined angle is same, then by SAS rule of similarity both triangles are similar.

From the given figure it is noticed that the ∠VZW and ∠YZX are vertically opposite angles. The vertically opposite angles are always equal.

$\angle VZW=\angle YZX$ (Vertically opposite angles)

$\frac{VZ}{YZ}=\frac{WZ}{XZ}$ (Given)

By SAS rule of similarity

$VWZ\sim YXZ$

Therefore the angles $\angle VZW\cong \angle YZX$ are used to prove the similarity of triangles VWZ and YXZ.

If U=pi(r+h),find r when U=16 1/2 and h=2<br> solve this question by take the value of pi 22/7

I am Lyosha [343]

$U=\pi (r+h) \\\\ 16 \frac{1}{2}= \frac{22}{7}\cdot (r+2) \\\\ \frac{33}{2} : \frac{22}{7}=r+2 \\\\ \frac{\not 33}{2}\cdot \frac{7}{\not 22}=r+2 \\\\ \frac{3}{2} \cdot \frac{7}{2}=r+2 \\\\ \frac{21}{4}=r^{(4}+2^{(4} \\\\ 21=4r+8 \\\\ 4r=21-8 \\\\ 4r=13 \\\\ \boxed{r=\frac{13}{4}}$
