Answer:

Numerator = 18

Denominator =75

Step-by-step explanation:

Given the expression

9/15=x/30=45/x

We can equate any two fractions

9/15= x/30

Criss multiply

15x = 9×30

15x = 270

x = 270/15

x= 18

Numerators is 18

Similarly

9/15 = 45/x

1/15 = 5/x

x = 5×15

x = 75

The denominator is 75

A hiker on the Appalachian Trail planned to increase the distance covered by 10% each day. After 7 days, the total distance trav
Anastaziya [24]

Answer:

  6.0 miles

Step-by-step explanation:

The sequence of distances is a geometric sequence with first term a1 and common ratio (1 +10%) = 1.10. The sum of 7 terms of the sequence is ...

  S7 = a1·(r^7 -1)/(r -1)

  56.923 = a1·(1.1^7 -1)/(1.1 -1)

  5.6923 = a1·0.9487171

Dividing by the coefficient of a1 gives its value:

  5.6923/0.9487171 ≈ 5.999997 ≈ 6.000

The hiker traveled 6.0 miles on the first day.

posledela

Answer:

4.17 centimeters

Step-by-step explanation:

The large bottle of nasal spray is 9.46 centimeters tall. Assuming that the large bottle of nasal spray has the shape of cylinder, then the height of the cylinder is 9.46 centimeters.

The small bottle is 5.29 centimeters tall. Assuming that the small bottle of nasal spray has the shape of a cylinder too, then the height of the cylinder is 9.46 centimeters.

We want to know how much shorter the smaller bottle is than the big bottle. This is calculated by

Height of big bottle - height of small bottle

= 9.46 centimeters. - 5.29 centimeters

= 4.17 centimeters
