Angle BCA =30 (angle in the same segment)
x=180-90-30=60
angle DBA =72/2 =36 (angle at centre twice angle at circumference)
y=36 (angles in alt segment)

the states C&D spend a total of 55.6 million dollars for tourism the state C spends 3.2 million dollars more than State D fi

Helga [31]

Alright, let's break this down.
State D blew 55.6 million bucks on tourism.
State C spends an unknown amount, we just know it's 3.2 million MORE than state D.
Well, since we know State D spent 55.6 million on tourism, just add 3.2 million to it to find out how much State C spent.
55.6+3.2=58.8.

This means the state's spent:
State D: 55.6
State C: 58.8

Which is the best estimate for StartFraction (8.9 times 10 Superscript 8 Baseline) Over (3.3 times 10 Superscript 4 Baseline) En

ratelena [41]

Answer:

$2.7 * 10^{4}$

Step-by-step explanation:

Given the expression $\frac{8.9*10^{8} }{3.3*10^{4} }$ , to express the the fraction in scientific notation, we will apply the law of indices below;

According to one of the laws of indices, $\frac{a^{m} }{a^{n} } = a^{m-n}$

Applying this to the fraction;

$= \frac{8.9*10^{8} }{3.3*10^{4} }\\\\= \frac{8.9}{3.3} * \frac{10^{8} }{10^{4} }\\\\ = \frac{8.9}{3.3} * 10^{8-4}\\\\ = \frac{8.9}{3.3} *10^{4}\\\\ = 2.697 * 10^{4}$
