Answer:

r = 2.5 \\ sum =  \frac{a( {r}^{n - 1} )}{r - 1}  \\  =  \frac{125( {2.5}^{7 - 1} )}{7 - 1}  \\  =  \frac{30517.6}{6}  \\  = 5086.3

What is the measure of
Sever21 [200]

Answer:

The measure of ∠G is 59°

Step-by-step explanation:

<em>When </em><em>two secants</em><em>, intersect at </em><em>a point outside a circle</em><em> then the </em><em>measure of the angle formed between them</em><em> is </em><em>one-half the positive difference of the measures of the intercepted arcs.</em>

<em></em>

In the given figure

∵ GT is a secant that intersects the circle at points H and T

∵ GE is a secant that intersects the circle at points F and E

∴ The intercepted arcs are HF and TE

∵ GT ∩ GE at G

∵ Point G is outside the circle

→ By using the rule above

∴ m∠G = \frac{1}{2} (m arc TE - m arc HF)

∵ m arc TE = 175°

∵ m arc HF = 57°

→ Substitute them in the rule above

∵ m∠G = \frac{1}{2} (175 - 57) = \frac{1}{2} (118)

∴ m∠G = 59

∴ The measure of ∠G is 59°

What is pi ? <br><br><br><br><br><br><br> ps. just trying this -.-
marysya [2.9K]
'Pi' ( π ) is the ratio of the circumference of a circle to its diameter.

The exact value of 'pi' can't be completely written with numbers, so whenever
we use 'pi', we always use an approximation.

A talk driver charges $3.50 per mile driver gives a 10mile ride a 5.5 mile ride and a 19 mile ride.he then spends $50 to fill up
salantis [7]

Answer: The driver has $95.25 after the last ride.

Step-by-step explanation: First we need to know how much money he recieved from each ride. Multiply 3.5 with each number.

$3.5 x 10 = $35

$3.5 x 5.5 = $19.25

$3.5 x 19 = $91

Now add them up.

$35 + $19.25 + $91 = $145.25.

However, he spends $50 on gas. So subtract $145.25 and $91.

$145.25 - $91 = $95.25.

Therefore, the driver has $95.25 after the last ride.
