Answer: You need to stack 6 blocks to build the block tower.
Step-by-step explanation:
Hi, to answer this question we simply have to divide the tower's height (7 1/2) by the side length of the cubes (1 1/4).
Mathematically speaking:
7 1/2 ÷1 1/4 = (7x2+1) /2 ÷ (1x4+1)/4 = 15/2 ÷ 5/4 = (15x4) / (2x5) = 60/10 =6 cubes
You need to stack 6 blocks to build the block tower.
Feel free to ask for more if needed or if you did not understand something.
Sum of angles in a triangle is 180 degrees.
2x + 2x + 8x = 180
12x = 180
x = 180/12 = 15
Therefore, the smallest angle mmeasures 2(15) = 30 degrees.
C. 6.25 in
Ratios and cross multiplication:
2 inches is to 130 feet as x is to 406.25 feet
2/130 = x/406.25
(2)(406.25) = (130)(x)
812.50 = 130x
Divide both sides by 130
x = 6.25
