Answer:
10.75 inches
Step-by-step explanation:
A 44-inch pendulum swings at an angle of 14°. Find the length of the arc to the nearest hundredth of an inch through which the tip of the pendulum swings.
The formula of the length of the arc subtended by pendulum is given as = (x/360)*2πr or (x/180)*πr
Where:-
x = angle subtended by pendulum which is = 14°
r = Length of the pendulum = 44 inch
Lenghth of arc = ?
By putting values
Length of the arc = (14/180 × π × 44
= 10.751228192 inches
Approximately = 10.75 Inches

4. For which of the following probability assignments are events A and B independent?
P(AN B“) – 0.3. P(AN B) = 0.12, and P(Aºn B) = 0.4.
B
P(An BC) = 0.3. P(An B) = 0.3, and P(Aºn B) = 0.3.
C) P(An Bº) = 0.1. P(ANB) = 0.1, and P(Aº n B) = 0.4.
P(An Bº) = 0.3. P (AnB) = 0.0, and P(
AB) = 0.2.
E) P(An Bº) = 0.5, P (ANB) = 0.1 and P (Aºn B) = 0.4
Answer:
A
Step-by-step explanation:
formatting is so bad lol
but yeah its the first one because for independent events, the probably of a and b is the product of both probabilities, just like how 0.3*0.4=0.12
Karen’s Kitty Korner offers cat sitting services for the pampered cats of Beverly Hills. During the week, she offers her cat sitting services $5 an hour along with an additional fee of $12. On the weekend, her fees change to $3 per hour and an additional fee of $18. After how many hours of cat sitting will her weekend rates be the same as her weekday rate?
Answer:
it would be 3
Step-by-step explanation:
because when you do 5×3=15 then +12= which gives you 27 and then do 3×3=8 then +18=which also gives you 27.
10. The angle measures of a triangle are shown in the diagram below.
(2x +1)°

x = 25
x = 14
x = 12
X= 7
A triangle with sides 9, 12 and 15 is similar to a triangle whose longest side is 25. Find the perimeter of the larger triangle.
Answer:
P = 60
Step-by-step explanation:
First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.
25 5
---- = ----
15 3
So the larger triangle is 5/3 times bigger.
This means that all of its other sides with also be 5/3 times bigger.
So:
9 (5/3) = 45/3 = 15
12 (5/3) = 60/3 = 20
25 + 15 + 20 = 60
So the perimeter is 60.
You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:
36 (5/3) = 180/3 = 60
You would get the same thing.
What is the slope for number 4?
Answer: -10/7
Step-by-step explanation:
John needs a plumber to repair the kitchen drain. The plumber charges $85 for the parts that he will need for the repair plus $30 for each hour worked. The maximum amount of money john can spend is $250. Which inequality would represent this situation if x is the number of hours worked?
Answer:
[tex]30x+85y\leq 250[/tex]
Step-by-step explanation:
Cost of each part is [tex]\$85[/tex]
Cost of working one hour is [tex]\$30[/tex]
Let number of hours worked be [tex]x[/tex] and
number of parts bought be [tex]y[/tex].
The maximum amount of money that John can spend is [tex]\$250[/tex].
From the question we have
[tex]30x+85y\leq 250[/tex]
The required inequality is [tex]30x+85y\leq 250[/tex].

Does 514, 684, 855 make a right triangle
Answer:
No, it does not.
Step-by-step explanation:
This does not make a right triangle because in order to have a right triangle you must have 2 of the same numbers.
For example:
900, 800, 900 makes a right triangle
900, 800, 700 does not.

If you have 4 red, 3 blue, and 5 green M&Ms and draw an M&M at random, what is the probability of the following. Write your answer as a fraction, decimal, and percent.
1. Red M&M
2. Green M&M
3. Green or Blue M&M
Answer:
1. 0.3333333
2. 0.4166666
3. 0.6666666
Step-by-step explanation:
add them all up for a total of 12. then divide 4 into 12 for the probability of number 1. Next, divide 5 into 12 for the probability of green. Finally, add 3 and 5 to get 8 and divide by 12.

Answer: (13.5 , 8)
14 + 13 / 2 = 13.5
14 + 2 / 2 = 8
Answer:
(13.5,8)
Step-by-step explanation:
midpoint formula = [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2})[/tex]
[tex](\frac{14 +13 }{2}, \frac{14 +2 }{2})[/tex] = (13.5,8)
