= 16 + 15 - (15 - 18)^2
= 31 - (-3(^2
= 31 - 9
= 22
answer
B. 22
Answer:
616 ft²
Step-by-step explanation:
Since the floor of the tepee is circular, we find its area by using the area of a circle.
So, A = πr² where π = 22/7 and r = radius of circular floor = 14 feet
So, substituting the values of the variables into the equation, we have
A = πr²
A = 22/7 × (14 ft)²
A = 22/7 × 196 ft²
A = 22 × 28 ft²
A = 616 ft²
So, the area of the floor of the tepee is 616 ft²
Answer: 178.1
(12.3x7)+(11.5x8)
86.1+92=178.1
Answer:
15:6:14
Step-by-step explanation:
AB:BD is split into a total of 3+4=7 parts.
AC:CD is split into a total of 3+2=5 parts.
So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).
AB would be (3/7)*35=15.
CD would be (2/5)*35=14
BC would be 35-(15+14)=6
So, the ratio is 15:6:14.
X+68.7=9.29 to get x by itself, you must subt. 68.7 from both sides
x=9.29-68.7 that would leave x by itself and now subt. the right side
x=-59.41 should be the answer
