Answer:  .81%

<u>Step-by-step explanation:</u>

Since each digit has to be greater than 6, that leaves only 7, 8, & 9 as successful digits.

Probability = \dfrac{successful}{total\ possible}=\dfrac{3\times 3\times 3\times 3}{10\times 10\times 10\times 10}=\dfrac{81}{10,000}=.0081=.81\%

2) Jarrah needs no less than $159 to purchase a new guitar. He already has $38 in his savings account. He
aleksandr82 [10.1K]

Answer: Jarrah has to rake 25 bags.

Step-by-step explanation: Jarrah

Jarrah needs to get $159 dollars, right? Well since he already has $38, we just need to subtract 159 and 38. 159-38 is 121. (121 is how much heneeds  )Each bag raked costs $5, and 5 can't go into 121, so it's best to have more than less. Multiply 5 and 25, and you will get $125. That is more than enough, you cannot do 5x24 because it would be 120, which is too low. Therefore, Jarrah needs to rake 25 bags.

So confused pls help me
Gala2k [10]

Answer:

a=49

Step-by-step explanation:

The angle having value (a+49)\textdegree is the exterior angle.

<em><u>Exterior angle of a triangle is equal to the sum of the other two opposite angles.</u></em>

Hence

a+49=a+a\\\\a+49=2a\\\\2a=a+49\\\\2a-a=49\\\\a=49
