Answer:

x = -2

Step-by-step explanation:

Let's find the required value of x,

→ 7 - 2x = 11

→ -2x = 11 - 7

→ -2x = 4

→ x = -4/2

→ [ x = -2 ]

Therefore, the value of x is -2.

Mohamed decided to track the number of leaves on the tree in his back yard each year. This year there were 500 leaves. Each year
makkiz [27]

Answer:

Geometric sequence

Step-by-step explanation:

According to the scenario, computation of the given data are as follows:

Leaves on tree this year (a) = 500

Rate of increase in leaves per year (r) = 40 % or 0.4

Let n be the number of years.

So we use exponential growth formula, i.e.

f(n) = a(1+r)^n

by putting the value, we get

f(n) = 500 ( 1+0.4)^n

or f(n) = 500 (1.4)^n

So, the common ration is 1.4.

Thus, it shows a geometric sequence.

The area of a circular field is 154msqu. What is the perimeter of the field?(pi=22/7) 44 49 88 176
OLga [1]

Answer:

44m

Step-by-step explanation:

A = \pir² = 154

   = 22/7 * r² = 154

   = r²  = 154 * 7/22

   = r²  = 49

   = r = √49

   = r = 7m

Perimeter of circle = 2\pir

                               = 2 * 22/7 * 7

                               = 44/7 * 7

                               = <u>44 m</u>

<u></u>
