<span>Let us use the variable x for length. So width will be 1/2x + 3. Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66 Therefore 3x = 66-6 = 60 So x = 60/3 = 20 The length is 20 cm. Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm Check: 20+20+13+13 = 66</span>

The index number representing the price level changes from 109 to 113 in one year. The inflation rate during the year is _____ p
Dima020 [189]

First, get the difference between the price level changes.

113-109=4

Then, divide it by the initial price level, which is 109.

\frac{4}{109}=0.0367

Multiply by 100 to get its percent.

0.0367\times100=3.67

Thefore, the inflation rate during the year is 3.67 percent.

To estimate the number of people in Springfield, population 10,000, who have a swimming pool in their backyard, 250 people were
Andrei [34K]

Answer:

2400 people

Step-by-step explanation:

Let x be the number of people who had a swimming pool in the population of 10,000,

Thus, the ratio of people who had swimming pool to the total population = \frac{x}{10000}

Since, out of 250 people 60 had swimming pool,

So, the ratio of the people who had swimming pool to the total population = \frac{60}{250}

\because \frac{x}{10000}=\frac{60}{250}

\implies 250x=600000

\implies x=\frac{600000}{250}=2400

Hence, 2400 people in the city might one expect to have a swimming pool.

First option is correct.

How to find a,b and c
alina1380 [7]
33/54 = 44/(a+44)
33(a+44) = 44*54
33a+ 1452 =  2376
33a = 924
    a = 28

c = sqrt (33^2 + 44^2)
c = sqrt(1089 + 1936)
c = sqrt(3025)
c = 55

33/54 = 55/(b+55)
33(b+55) = 55*54
33b+ 1815 =  2970
33b = 1155
    b = 35

answer
a = 28, b = 35, c = 55
