Answer: Hello,

$1) \ncos(\widehat{HKR})= (9)/(41) ==\ \textgreater \ \widehat{HKR}=1.34948188...rad\n\nsin(\widehat{KHR})= (9)/(41) ==\ \textgreater \ \widehat{KHR}=0,22131444...rad\n\n$

$\widehat{QKA}=\pi-1,34948188...=1,792110769...rad\n\n$\overset{\frown}{QA}$=24*1,792110769...=43,010658459...\n\n\widehat{KHB}= (\pi)/(2)-0,22131444...=1,3494888...\n\n$\overset{\frown}{PB}$=15*1,3494888...=20,2422282\n\n$

2)
$|HR|=√(9^2+41^2) =41,976183723\n\n$

length=2*(43,010658459+20,2422282+41,976183723)=210,458140764

i made a clay snake 9 5/8 inches long, but a section 1 7/8 inches long broke off. how longis the snake now?

Answers

The answer is 7 3/4.
Turn into improper fraction
= 77/8 − 15/8

= ((77 × 8) − (15 × 8)) / (8 × 8)

= (616 - 120) / 64

= 496/64

= 31/4

First, I would convert it an improper fraction.9 5/8 = 77/81 7/8 = 15/877 - 15 = 62. The denominator stays the same.62/8. Divide to make it a mixed number.62/8 = 7 6/8Simplified to = 7 3/4

Randi and her distant sold ballons for .50 they made 48$ if Randy has twice as many balloons as your sister how many balloon animals did each girl make

Answers

Answer:Randy made 64 balloon animals and his sister made 32 balloon animals.

Step-by-step explanation:

Let x represent the number of balloon animals that Randi made.

Let y represent the number of balloon animals that her sister made.

Randi and her sister made balloon animals and sold the for. $0.50 each at the school carnival. They made $48.00. This means that

0.5x + 0.5y = 48 - - - - - - - - - -1

Randi made twice as many balloons as her sister. This means that

x = 2y

Substituting x = 2y into equation 1, it becomes

0.5 × 2y + 0.5y = 48

y + 0.5y = 48

1.5y = 48

y = 48/1.5 = 32

x = 2y = 2 × 32

x = 64

Randi has 32 balloons and the other girl has 16 simply divided 48/3
