Tully draws four 10 - sticks and less than ten circles to make a number. Write the numbers Tully could make

ruslelena [56]

The numbers Tully can make are 41, 42, 43, 44, 45, 46, 47, 48 and 49

Solution:

Given that Tully draws 4 sticks , each one with value 10

This means that the numbers will be of the set of four tens: 4(10) = 40

Also given that less than ten circles to make a number

We assume that the circles have each value of 1 unit

For circle, Therefore the possible units are: 1, 2, 3, 4, 5, 6, 7, 8, 9

Combining together sticks and circles, the possible numbers are given as follows:

sticks + circle :

$4(10) + 1 = 41\\\\4(10) + 2 = 42\\\\4(10) + 3 = 43\\\\4(10) + 4 = 44\\\\4(10) + 5 = 45\\\\4(10) + 6 = 46\\\\4(10) + 7 = 47\\\\4(10) + 8 = 48\\\\4(10) + 9 = 49\\\\$

Therefore, the numbers Tully can make are 41, 42, 43, 44, 45, 46, 47, 48 and 49

Currently, the number of people entering a shopping mall is 109. It is estimated that the number of people entering the shopping

seropon [69]

Answer:

96 people.

Step-by-step explanation:

Exponential equation for a decreasing amount:

The exponential equation for a decreasing amount is given by:

$A(t) = A(0)(1-r)^t$

In which A(0) is the initial rate and r is the decay rate, as a decimal.

Currently, the number of people entering a shopping mall is 109.

This means that $A(0) = 109$

It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.

This means that $r = 0.03$

$A(t) = A(0)(1-r)^t$

$A(t) = 109(1-0.03)^t$

$A(t) = 109(0.97)^t$

Find the total number of people entering the shopping mall at the end of 4 hours.

This is A(4). So

$A(4) = 109(0.97)^4 = 96.49$

Rounding to the nearest whole number, 96 people.

Which of the following statements is true?. . A.A tangent is never a secant.. B.A secant is always a chord.. C.A chord is always

skelet666 [1.2K]

The correct answer is:

A) A tangent is never a secant.

Explanation:

A tangent is a line that touches a circle in exactly one point. A secant is a line that touches a circle in two different points.

Since a tangent only touches once and a secant touches twice, there is no way a tangent can be a secant.
