Answer: D. 8.50a + 6.75k + 1.75(a + k)
Step-by-step explanation:
Cost of adult meal = $8.50
Cost of kid meal = $6.75
Cost of drink = $1.75
Number of adults = a
Number of kids = k
Since everyone orders a meal and
a drink, the expression that can be used to express the total cost of the meal will be:
Cost for adults:
= (8.50 × a) + (1.75 × a)
= 8.50a + 1.75a
Cost for kids:
= (6.75 × k) + (1.75 × k)
= 6.75k + 1.75k.
To get the total cost, we add the cost for adults and kids together. This will be:
= 8.50a + 1.75a + 6.75k + 1.75k.
= 8.50a + 6.75k + 1.75a + 1.75k
= 8.50a + 6.75k + 1.75(a + k)
Therefore, the correct option is D.
Answer:
x=5.9
Step-by-step explanation:
tan(26)=x/12. x=12*tan(26)=5.9
Answer/Step-by-step explanation:
You see that there is 3, 2s there. Meaning you add them up and use the amount there is as your exponent.
so your answer is
Since QP and QB are equal the triangle PQB the angles:
The last angle can be found by adding all the internal angles and making it equal to 180 degrees.
The angle BQP and the angle AQP are suplementary, this means that their sum is equal to 180 degrees. So we have:
Since the sides AP and PQ are equal, then the angle PAQ is equal to AQP.
To find the last angle on that triangle we can add all the internal angles and make it to 180 degrees.
The angle APC is suplementary with the sum of the angles APQ and BPQ. So we have:
The sides AP and AC are equal, therefore the angles APC and ACP are also equal.
Then we can find the last angle on that triangle.
The angle CAB is equal to the sum of CAP and PAQ. So we have:
Since the sides AB and BC are equal, then the angles ACB and CAB must also be equal. We can find the value of x with this.
The value of x is 180/7
The inverse value of sin⁻¹(A) = Ф° , is sin(Ф) = A
sin(Ф°) = (-√3)/2 THAT MEANS Ф = -60° OR Ф = 300°
