Answer:

A 5 and B 35

Step-by-step explanation:

sides are 15 and 20 the third side has to be

less than 15+20 =35

Answer:

greater than 5 and less than 35

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is

difference of 2 sides < x < sum of 2 sides, that is

20 - 15 < x < 20 + 15

5 < x < 35

Thus the third side is greater than 5 and less than 35

Swimming Pool On a certain hot summer's day, 253 people used the public swimming pool. The daily prices are $ 1.50 for children

e-lub [12.9K]

Answer:

Therefore 164 children and 89 adults swam at the public pool that day.

Step-by-step explanation:

Given that,

253 people used the public swimming pool.

The daily prices for children are $1.50 and for adults are $2.25.

Let the number of children be x.

Then number of adult is (253-x)

The total money collect on that day is $=\$[(1.50\times x)+2.25(253-x)]$

$=\$[1.50x+569.25-2.25x]$

$=\$[569.25-0.75x]$

According to the problem,

$569.25-0.75x=446.25$

$\Rightarrow -0.75 x=446.25-569.25$

$\Rightarrow -0.75 x=-123$

$\Rightarrow x=\frac{123}{0.75}$

$\Rightarrow x=164$

Therefore 164 children and (253-164)=89 adults swam at the public pool that day.

Answer:

1) a1 = -5, a(n) = a(n-1) + 2

Step-by-step explanation:

The explicit formula for an arithmetic sequence can be written ...

an = a1 +d(n -1)

The corresponding recursive formula is ...

a(1) = a1, a(n) = a(n -1) +d

Comparing the above explicit formula to the one you're given, you see that ...

a1 = -5, d = 2

Using these values in the recursive formula gives you ...

a(1) = -5, a(n) = a(n-1) +2
