Answer:

1/18 or 5.55...% 2nd question: 10,000

Step-by-step explanation:

She has a one in 6 odds for the dices, and every one for those odds she also has 1 in 3 for the spinner, so you just multiply them.

2nd question: you have to do this differently. This one you need to multiply 10 by 10 by 10 by ten, because for each there are 10 1,2,3,4,5,6,7,8,9,0, so there can be ten in each, so you get 10,000

A music store sold a total of 27 used trumpets and clarinets in one month. Trumpets cost $149 and clarinets cost $99. If total s

Annette [7]

Answer:

The number of clarinets musical store sold was 16. and number of trumpets musical store sold was 11.

Step-by-step explanation:

Let the musical store sells 'x' number of trumpets and 'y' number of clarinets.

According to question,

Total number of trumpets and clarinets sold is 27 that is

$x+y=27$ ..............(1)

Also given Trumpets cost $149 and clarinets cost $99.

then the shop sold x trumpets for $149x and sold y clarinets for $99y and total sales were $3233.

thus, $149x+99y=3233$ ...........(2)

Solving for equation (1) and (2),

Multiply equation (1) by 149 , we get

(1) ⇒ $149x+149y=4023$ ........(3)

Now, subtract equation (3) from equation (2) , we get

$149x+149y-(149x+99y)=4023-3233$

$\Rightarrow 149x+149y-149x-99y=790$

$\Rightarrow 149y-99y=790$

$\Rightarrow 50y =790$

$\Rightarrow y =\frac{790}{50}=15.8$

Thus, number of clarinets musical store sold was 15.8 but since clarinets are to be in whole number rounding off to the nearest integer 16.

and put y = 16 in (1) , we get

$x+y=27 \Rightarrow x+16=27 \Rightarrow x=27-16=11$

Thus, number of trumpets musical store sold was 11.
