Answer:

New balance = -151.89 + 4.5x

(where x is the value of the smaller deposit)

Step-by-step explanation:

The inicial balance was -126.89.

Then, it were made two deposits, one with the value of x, and one that is 3 1/2 times the other, that is, 3.5x.

Then, the customer made a withdraw of $25.

So, The new balance can be calculated as:

New balance = inicial balance + x + 3.5x - 25

New balance = -126.89 + 4.5x - 25

New balance = -151.89 + 4.5x

The graphs of f(x) and g(x) are shown below:
Elodia [21]

Answer:

-3.8, 3

Step-by-step explanation:

The solution to a system is where the graph cross each other.  If you look to where they intersect to the left of the origin, where x is negative, it appears that they intersect ALMOST at -4, but not quite.  So -3.8 is going to have to do since we don't have the equations of either graph to find the exact values of x.  To the right of the origin, where x is positive, the graphs cross where x = 3..

A circle has been dissected into 16 congruent sectors. The base of one sector is 1.17 units, and its height is 2.94 units. Using
worty [1.4K]

Answer:

The approximate area of the circle is 27.5184∧2

Step-by-step explanation:

In order to calculate the approximate area of the circle we would have to calculate the following formula:

approximate area of the circle=approximate area of one triangle*number of congruent sectors

number of congruent sectors=16

approximate area of one triangle=1/2*base*height

base=1.17 units

height=2.94 units

Therefore, approximate area of one triangle=1/2*1.17*2.94

approximate area of one triangle=1.7199 units∧2

Therefore, approximate area of the circle=1.7199 units∧2*16

approximate area of the circle=27.5184∧2

If he paints 1/2 of the wall blue, hoy many square feet will be blue?
Katen [24]

To determine how much of the wall is blue we first need to find its area. The wall is a rectangle, then its area is the product of its height and length:

\begin{gathered} A=(8\frac{2}{5})(16\frac{2}{3}) \\ A=(\frac{42}{5})(\frac{50}{3}) \\ A=(14)(10) \\ A=140 \end{gathered}

Hence, the area of the wall is 140 square ft. To determine how much of the wall is already painted we multiply this by 1/2, then:

(140)(\frac{1}{2})=70

Therefore, 70 square ft are blue.
