Answer:
r = 1.9
Step-by-step explanation:
7r + 7 = 20.3
<u> - 7 - 7 </u>
7r = 13.3
divide by 7
r = 1.9
130.80 is the answer you have to multiply 120 times 1.09
Answer:
a medium smoothie cost $3.25
Step-by-step explanation:
j = 4.95 which is the cost of one jumbo
equation from word problem
2j + m = 4m + 0.15
subtract m from both sides
also subtract 0.15 from both sides
2j - 0.15 = 3m
substitute j
2(4.95) - 0.15 = 3m
9.75 = 3m
m = 3.25 or $3.25
Answer:
R= 20.88 ft
Step-by-step explanation:
See the diagram attached, this satisfies the condition, ΔKLM is enclosed in a circle of radius R.
LN=16 ft (given)
The value of KM is 2R because as the ∠KLM forms an angle of 90°, therefore, the line KM passes through the center.
Area of a triangle =
Now let's find he area of the ΔKLM=
=
Also the area can be found out by =( As KLM is a right angled triangle)
KL= KM cos 25°= 2R cos 25°
LM= KM cos 55°= 2R sin 25°
Area= x 2R cos 25°x 2R sin 25 °
= sin 50°
sin 50°= 16R
R sin 50°=16
R= 20.88 ft
