Ответ:
sqrt(6)
Step-by-step explanation:
In a 45-45-90 right triangle, the ratio of the lengths of the sides is
1 : 1 : sqrt(2)
u = sqrt(3) * sqrt(2) = sqrt(6)
Ответ:
√6 meters
Step-by-step explanation: In a 45° right triangle, the two sides of the 90° angle are equal. a^2+b^2=c^2
2(√3)^2 = 6
√c^2 = √6.
Ответ:
24 blocks will be needed to make the tower that is 4 feet high
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ Charlie knows that 3 blocks are needed to make a tower that is
0.5 foot high
∵ He needs to make a tower that is 4 feet high
→ By using the ratio method
→ Blocks : height (ft)
→ 3 : 0.5
→ x : 4
→ By using the cross multiplication
∵ x × 0.5 = 3 × 4
∴ 0.5x = 12
→ Divide both sides by 0.5 to find x
∵
= ![\frac{12}{0.5}](/tpl/images/0901/4995/a3aa6.png)
∴ x = 24
∵ x represents the number of blocks
∴ 24 blocks will be needed to make the tower that is 4 feet high
