Answer:

1. 9 = x

2. y = 2

Just copy these steps on paper, then submit.

Writing it yourself will help you, trust me :)

1. 2(x + 5) = 3x + 1

2(x + 5) = 3x + 1

Distribute the 2

2x + 10 = 3x + 1

-1 -1

2x + 9 = 3x

-2x -2x

9 = x

2. 3y - 4 = 6 - 2y

3y - 4 = 6 - 2y

+4 +4

3y = 10 - 2y

+2y +2y

5y = 10

Divide both sides by 5

y = 10/5

y = 2

Find the volume of a right circular cone that has a height of 2.5 m and a base with a diameter of 18.6 m. Round your answer to t

dem82 [27]

Answer:

226.4 m³.

Step-by-step explanation:

The volume of a right cone with a circular base is:

$\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h$ ,

where

$V$ is the volume of the cone,
$r$ is the radius of the cone,
and $h$ is the height of the cone.

The radius of the circular base is one-half its diameter.

$\displaystyle r= \frac{1}{2}h=9.3\;\text{m}$ .

$\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h = \frac{1}{3} \pi \times 9.3^{2} \times 2.5 \approx 226.4\;\text{m}^{3}$ .

in a survey of 3271 adults aged 57 through 85 years, it was found that 88.7% of them used at least one prescribed medication

mixer [17]

How many of the 3271 subjects used at least one prescription medication? Round to the nearest integer asneeded.)

Answer:

2902

Step-by-step explanation:

Let the total number of adults within the mentioned age bracket be n=3271

The proportion of adults who used at least one prescription medication be p=88.7%=0.887

The point estimate of population is given by

$p=\frac {x}{n}$ where x is number of individuals in the sample with the specified characteristics and n is the sample size.

Let x be the adults who used at least one prescription medication

$0.887=\frac {x}{3271}$

$x=3271*0.887=2901.377\approx 2902$
