Answer: 70º
Step-by-step explanation:there are two angles with the same measurement on the vertices, therefore with the same angle. A triangle has a sum of 180º in the inside angles. 55º+55º=110º, and 180º-110=70º
Answer:
which agrees with the second answer in your list
Step-by-step explanation:
First thing to do, is organize in your mind what is asked of the problem. Since the problem talks about total cost, then you are dealing with monetary units of measurement. Next, you investigate on the variables given and what they represent. Looking at the following expressions, I could not immediately get a hint on what these terms stand for. But for letter c, I deduced that that would be the overall equation representing the total cost.
The first term, 0.25x, must be the cost of the phone units purchased under the plan . That means each cellphone unit used costs $0.25 each. The second term, 2y, must be the cost of data used by the plan. So, that means each megabyte used up costs $2. These two costs must be what is referred to by the additional costs. Lastly, the last term, '55'. is the fixed cost when you subscribe to the amount per month. Hence, the equation in letter C represents the total cost per month.
Answer:
80 ice cream bars were left
Step-by-step explanation:
50 × 12 = 600 so there was 600 ice cream bars altogether.
600 - 520 = 80
There are two formulae for this:
<span>angle/360 X (pi) X (radius squared) = Area of a sector </span>
<span>angle/360 X (pi) X (diameter) = Arc Length of sector </span>
<span>or </span>
<span>angle/360 X (2) X (pi) X (radius) = Arc Length of sector </span>
<span>If you want to work out the perimeter of a sector, use this formula: </span>
<span>Arc Length + (2 X radius) = Perimeter of sector. </span>
