Answer:

116

Step-by-step explanation:

Given shape has 6 angles and the sum of interior angles for this shape is calculated as following:

180*(6-2) = 720 now to find x we need to find the sum of given angles first:

144 + 163 + 50 + 131 + 126 x = 720

614 + x = 720 subtract 614 from both sides

x = 116

Pls help find shaded area

Pavlova-9 [17]

<h3>Exact area = 12pi - 9*sqrt(3) square inches</h3><h3>Approximate area = 22.1106545749577 square inches</h3>

==========================================================

Work Shown:

Assuming the chord is horizontal along with the diameter, then this means the two smallest minor arcs are both 30 degrees each. This leaves the northern most arc to be 180-30-30 = 120 degrees in measure

A = area of northern sector (you can think of it as a pizza slize)

A = (angle/360)*pi*r^2

A = (120/360)*pi*6^2

A = 12pi

B = area of triangle

B = (1/2)*side1*side2*sin(included angle)

B = (1/2)*6*6*sin(120)

B = 18*sqrt(3)/2

B = 9*sqrt(3)

C = area of shaded region

C = A - B

C = 12pi - 9*sqrt(3) .... exact area

C = 22.1106545749577 ... use a calculator to get the approximate area

Tan's electricity bill for the month of August was $267.00. His September bill showed a 2% increase from his August bill. In Oct

vovikov84 [41]

267 x 0.02 = 5.34
267 + 5.34 = 272.34

267 x 0.08 = 21.36
267 - 21.36 = 245.64

267 + 272.34 + 245.64 = $784.98

Jane is saving to buy a cell phone. She is given a $100 gift to start and saves me

Dmitriy789 [7]

Answer:

See explanation

Step-by-step explanation:

Jane is given a $100 gift to start and saves $35 a month from her allowance.

After 1 month, Jane has saved $\$100+\$35=\$135;$
After 2 months, Jane has saved $\$100+2\cdot \$35=\$170;$
After three months, Jane has saved $\$100+3\cdot \$35=\$205;$
and so on

In general, after x months Jane has saved

$\$100+x\cdot \$35=\$(100+35x).$

This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.
