Step-by-step explanation:

Answer:


Last choice is correct.


Step-by-step explanation:


Given that ∠C=90°, ∠B=30°, c=10


We know that sum of all angles in a triangle is 180 degree.


∠A+∠B+∠C=180°


∠A+∠30°+∠90°=180°


∠A+∠120°=180°


∠A=60°


Now we can use sin or cos whichever applicable to find missing sides


2b=10


b=5


Similarly


a=8.6602


Hence last choice is correct.

Answer:

Peggy is correct, their total bakes sale = $396.75

Step-by-step explanation:

Using estimation to help Peggy explain why Leslie reasoning is incorrect.

From the question we can see that:

First bake sale they made = $79.35

4 more bake sales making the same amount = 4 × $79.35

The total amount they would make from the bake sales =

$79.35 + (4 × $79.35)

= $396.75

Peggy was right. Leslie's reasoning was incorrect.

photoshop1234 [79]

Answer:

111111

Step-by-step explanation:

Digit 1: This can be any digit as all numbers are divisible by 1. I picked 1 because it was simplest.

Digit 2: The total needs to be divisible by 2, so I picked my total to be 2. I knew I already had 1 from the previous digit, so 2-1 =1 was my next digit.

Digit 3: The total must be divisible by 3, so I picked my total to be 3. I already had 2 from the two previous digits, so 3-1 = 1 was my next digit.

I hope you get the idea now, it follows the same pattern for the rest of the numbers.

Hopefully this helps, any questions let me know :)

goblinko [34]
Your problem did not have an operator between the x and 1 so I did it as subtraction and addition. There was no answer choice -3 so D x=-9 is the answer
