Answer: 17 patients stayed for longer than 10 minutes.
Step-by-step explanation:
Let x represent the number of patients that stayed for longer than 10 minutes.
The doctor charges $21.80 for consultations that last less than 10 minutes and $27.50 for those that last longer than 10 minutes. Yesterday the doctor earned $1077.90. If 28 consultations lasted less than 10 minutes, it means that
28 × 21.80 + x × 27.50 = 1077.90
610.4 + 27.5x = 1077.9
27.5x = 1077.9 - 610.4
27.5x = 467.5
x = 467.5/27.5
x = 17
Answer:
12 milkshake can be made by 1/3 cup
1 milkshake can be made by (1/3)/12 cup
72 milkshake can be made by ((1/3)/12)*72 cup = 2cup

Answer:
54°
Step-by-step explanation:
The two strokes on each side of the triangle show that the triangle is an isosceles triangle and ∠KJL and ∠KLJ are equal. The sum of angles in a triangle is 180°.
∠KJL + ∠KLJ = 180° - 72°
= 108°
∠KJL = 108° ÷ 2
= 54°
His distance from one end is ' D ', and his distance from the other end is ' 2D '.
The distance from one end to the other end is (D + 2D) = 3D .
3D = 1,049 miles
Divide each side by 3 :
D = 1,049 / 3 = 349 and 2/3 miles .
The question doesn't tell which end he started from, and where he's headed,
so I guess you have to know that this is the Iditerod race, it STARTS in Anchorage,
and it ENDS in Nome.
He is ' 2D ' from Anchorage, so he has completed [ 2 x (349 and 2/3 miles) ] =
699 and 1/3 miles.
Rounded to the nearest mile, that's 699 miles.
Answer:
Step-by-step explanation:
given :
y = 120 degree
z = 57 degree
angle x = ?
first lets find angle c in triangle BDC
<h3>angle c + z = y (sum of two interior opposite angle is equal to the exterior angle formed)</h3>
angle C + 57 = 120
angle C = 120 -57
angle C = 63 degree
Now lets find angle B in triangle BDC
angle B + angle C + z = 180 degree (sum of interior angles of a triangle)
angle B + 63 + 57 = 180
angle B + 120 = 180
angle B = 180 - 120
angle B = 60 degree
now for angle x
angle B + z = angle x (sum of two interior opposite angles is equal to the exterior angle formed)
60 + 57 = x
117 = x
