Answer:
30°, 30° and 120°
Step-by-step explanation:
Using the information given in the question.
let x be the measure of each congruent base angle , then
the third angle = 3x + 30
Sum the 3 angles and equate to 180
3x + 30 + x + x = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Thus
The 2 congruent bas angles are each = 30°
The third angle = 3x + 30 = 3(30) + 30 = 90 + 30 = 120°
Answer:
The answer is 118.
Step-by-step explanation:
First we need to subtract the meal cost from average unit cost for each meal:

A restaurant profits 1.25$ for each meal. If we divide fixed cost to profit for each meal:

The restaurant have to sell 118 meals at least each day for the owner to break even
Lets begin with our y=mx+b, our constant(b) is 800 that she earns as a salary, our x represents the amount she sells, m then represents the commission which is 8.25% so converting that to a decimal and replacing it as m gets us y = 0.0825x+800. Replace $4500 for x and we have y=0.0825(4500)+800 solve and we get $1171.25
Answer:
Step-by-step explanation:
m= y2 - y1/x2 - x1
m= -3 - 8
/1 - 2
m=-11/-1
m=11
(34/8 - 16/9) = 89/36
(89/36 - 14/9) = 11/12
ANSWER: 11/12
