729 ÷ 3 = 243
so if you do 243 × 3 = 729
so your answer will be 243
Answer: Multiplying the number by 2.5
Step-by-step explanation:
Jay took a number, n, and increased it by 25%. The value gotten will be:
= n + (25% × n)
= n + (0.25 × n)
= n + 0.25n
= 1.25n
After that, Then, he doubled the resulting product. The value now gotten will be:
= 2 × 1.25n
= 2.50n
Therefore, the equivalent will be multiplying the number by 2.5. This will be:
= n × 2.5
= 2.5n
Therefore, it's thesame with the value gotten.
The correct option is D.
Answer:
7/8
Step-by-step explanation:
Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters.
WE need find which factor is multiplied with radius of sphere A to produce the radius of sphere B
Diameter of sphere B is 42
Radius = diameter /2
Radius = 42/2= 21
Radius of sphere B = 21
RAdius of sphere A times x= radius of sphere B
24 * x= 21
Divide by 24 on both sides
x= 21/ 24
divide top and bottom by 3
x= 7/ 8
