Answer:40 square yards
Step-by-step explanation:
Given
Floor area A=10 square yards
Red tile costs per square yards
White tile costs per square yards
Total money spent= on tiles
Suppose red tiles cover an area of square yards
So, we can write
Red tiles cover an area of 40 square yards
Answer:
12 black beads
Step-by-step explanation:
Given the ration of gold beads to black beads on the short necklace:
Since the ratio of 4:1 has 5 total parts, you can take the total amount of beads in the long necklace and divide by 5:
60 ÷ 5 = 12
12 beads represents 1 part of the ratio, so that would be the number of black beads. To check, multiply 12 by 4: 12 x 4 = 48, and set up a ratio:
48: 12 = 4: 1
