Answer:
The legs of a 45 45 90 triangle are congruent so if one leg is x we can write (using the Pythagorean Theorem):
x² + x² = 18²
2x² = 324
x² = 162
x = 9√2
Yes, because 1/4 plus 1/4 equals 2/4 (or 1/2) and 3/4-2/4 equals 1/4.
the distance between (8,0) and (1,0) is 7 units
(a)
10 miles ーー> 65 minutes
1 mile ーー> 65 minutes ÷ 10 = 6.5 minutes
∴ Chau takes 6.5 minutes to run 1 mile.
(b)
16 pound ーー> $9
1 pound ーー> $9 ÷ 16 = $0.5625
∴ Diane paid $0.5625 per pound of rice.
Answer:
Number of tile package need = 55 package of tile
Step-by-step explanation:
Given:
Base of parallelogram = 25 feet
Height of parallelogram = 11 feet
Each package of tile cover = 5 square feet
Find;
Number of tile package need
Computation:
Area of parallelogram = Base of parallelogram x Height of parallelogram
Area of parallelogram = 25 x 11
Area of parallelogram = 275 square feet
Number of tile package need = Area of parallelogram / Each package of tile cover
Number of tile package need = 275 / 5
Number of tile package need = 55 package of tile
