Answer:

\boxed{

\boxed{

Step-by-step explanation:

A) If AB is a diameter, Then ACB is a 90 degrees angle because In a semi-circle (AB is a diameter which divides the circle into 2 equal parts), the angle opposite to the diameter is of 90 degrees.

So, <ACB = 90 degrees

Then <a = 180-90-28

=> <a = 62 degrees

B) The opposite interior angles of a quadrilateral inscribed in a circle add up to 180 degrees.

So,

=> <a + <b = 180

=> <b = 180-62

=> <b = 118 degrees

One soda and one taco costs $2.1. Two sodas and three tacos cost $5.15. Find the cost of a soda and a taco. Whoever answer this
DaniilM [7]

Answer:

Soda costs $1.15 and taco costs $0.95.

Step-by-step explanation:

x + y = 2.1

2x + 3y = 5.15

Multiply the first equation by -2 to eliminate x

-2x - 2y = -4.2

2x + 3y = 5.15

Add

          y = 0.95

Find x with the original first equation

x + y = 2.1

x + 0.95 = 2.1

x = 2.1 - 0.95

x = 1.15

hope it helps :)

Simplify the expression. (3.14×107)×(1.3×10−3)÷0.2<br> Scientific notation PLS!
marusya05 [52]

3.14 \times 107 = 335.98
(335.98) \times (1.3 \times 10 - 3) \div 0.2
1.3 \times 10 = 13 - 3 = 10
(335.98) \times (10) \div 0.2
335.98 \times 10 = 3359.8
3359.8  \div 0.2 = 16799
1.6799 \times  {10}^{4}
