The circumference of the circle below is 20 cm. What is the length of AB (the minor arc)?
SOVA2 [1]

Answer: AB=5.27\ cm

Step-by-step explanation:

For this exercise it is important to remember that, by definition, the length of the minor arc can be calculated wih the following formula:

arc\ length=(\frac{central\ angle}{360\°})(circumference)

In this case , according to the data given in the exercise, you know that:

arc\ length=AB\\\\central\ angle=95\°\\\\circumference=20\ cm

Therefore, susbtituting those values into the formula, you get that length of AB is the following:

AB=(\frac{95\°}{360\°})(20\ cm)\\\\AB=(\frac{191}{72})(20\ cm)\\\\AB=5.27\ cm

Given |u| = 10 at ∠135° and |v| = 5 at ∠30°, what expression can be used to find |u + v|?
astraxan [27]

Answer:

B, 10^{2} + 5^{2}- 2(10)(5)cos(75)

Step-by-step explanation:

Using the law of cosines, which is c^{2}=a^{2}+b^{2}-2ab cos(C), you can simply insert all the values.

c=|u+v|

a= r value of u (10)

b= r value of v (5)

To find  C, you simply have to subtract v from u, and then subtract that number from 180 to find the reference angle.

I.E.: ∠135 - ∠30 = ∠105 ↔ 180 - 105 = 75 =  C

so, the completed equation would be 10^{2} + 5^{2}- 2(10)(5)cos(75)

An animal shelter spends $3.50 per day to care for each bird and $6.50 per day to care for each cat. Brooklyn noticed that the s
Vikki [24]

Solution: Let x be the number of birds and y be the number  of cats.

x+y=29 \implies y=29-x

3.50 x +6.50 y= 146.50

3.50 x+6.50(29-x)=146.50

3.50x+188.5-6.5x=146.50

3x=188.5-146.50

3x=42

x=\frac{42}{3} =14

Therefore, there were 14 birds at the shelter on Friday
