If arc SQ = 84° and ∠RPS = 26°, what is the measure of arc RS?

2 answers:

7 0

The arc RS would be 250 degrees if the RPS is the central angle and if the angle is on the circumference then the angle would be 224.

Answer:

D = 23.7 miles

Step-by-step explanation:

Given data:

$\theta=84 degrees$

Time $= 20 min = \frac{1}{3} hr$

Distance of A $= (60 mi/hr)\times \frac{1}{3} hr =20 mi$

Distance of B = $(45 mi/hr)\frac{1}{3} hr = 15 mi$

Draw a triangle.

By using cosine formula we can determine the distance between them

$D^2 = 20^2 + 15^2 - 2\times 20\times 15\times cos(84)$

$D^2 = 625 - 600 cos(84)$

$D^2 = 625 - 63.2$

$D^2 = 561.8$

Thus D = 23.7 miles

An opaque bag contains 5 green marbles 3 blue marbles and 2 red marbles. If a marble is drawn at random what are the odds of dra

melamori03 [73]

Answer:

Odds are 3 to 7

Step-by-step explanation:

The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.

Let's find:

Probability of blue marble = 3/10 [ 3 blue and 10 in total]

Probabilty of NOT blue marble = 7/10 [7 marbles are red and green (not blue) and 10 in total]

Hence,

Odds of drawing a blue marble = $\frac{\frac{3}{10}}{\frac{7}{10}}=\frac{3}{10}*\frac{10}{7}=\frac{3}{7}$

The odds are 3 to 7

Nady [450]

A = 210 + 20(h - 7) <== ur equation

if she earns 410 tutoring...
410 = 210 + 20(h - 7)
410 = 210 + 20h - 140
410 = 20h + 70
410 - 70 = 20h
340 = 20h
340/20 = h
17 = h <=== she spent 17 hrs tutoring
