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.

i don't know what the math is. i would like to try to help
Step-by-step explanation:
Hey there!
To start, none of these triangles appear to have a given height, only a given angle. Another thing to notice is that neither of these triangles are right. This means that you would need to use the function of sine to calculate the area of the triangle.
First, you know that the sine triangle area formula is:
A= 1/2*side*side*sin(given angle)
Knowing that the area of ΔABC is 30, the sides given are x and y, and the angle is 70, you can set up this equation:
1/2*xy*sin(70)=30
Now, solve for xy:
2(1/2*xy*sin(70)=30)
=xy*sin(70)=60
=xy=60/(sin(70))
Now, use the same formula to solve for the area of ΔPQR knowing that xy=60/(sin(70)).
1/2*60/(sin(70))*sin(110)
=30 cm squared
Therefore, the correct answer would be 30.
Hope this helps!
Answer:
1. 6.4 meters of streamers left to make pompoms
2. He will be able to make 8 pompoms
Step-by-step explanation:
1.
4 x 1.6 = 5.6 meters were used to make decorations.
Then we do 12 - 5.6 = 6.4
2.
per one pompom it takes 0.8 meters of streamers.
6.4 is the left over so we do
6.4 divided by 0.8 = 8 pompoms you can make
