Answer:
1st Picture: d = -16
2nd Picture: g = -13.8
Step-by-step explanation:
1st Picture: Divide both sides by -11 to balance both sides and get the answer.
2nd Picture: Subtract 1.2 from both sides.
Lets get started :)
The First question:
Diameter = 20 ft
Radius =

of 20 (diameter) = 20 ft
Area formula of a circle is
A =

r²
=

(10)²
=100

ft²
≈ 314 ft²The answer will be the second optionThe Second question:
radius of circle = 12mm divided into 20 sectors area
A =

r²
=

(12)²
= 144

ft²
Divide into 20 equal sector areas =
≈ 22.6 mm²Your answer will be the third optionThe Third Question:
90°, sector area = 36

, Radius = ?



and

cancels out
We can now cross multiply
360 × 36 = 90r²
12960 = 90r²
Divide by 90 on either side

144 = r²
Take squareroot
x = 12 inYour answer will be the third option
$2 per notebook would be the correct answer
We have been given a table of overnight low temperature for a four-day period. We are supposed to give a possible temperature for Wednesday.
We are told that the low temperature on Wednesday was between the second and third highest temperature.
Let us place our given temperatures from least to greatest order.
Sunday (-11), Thursday (-8), Friday (7), Sunday (18)
We can see that second and third highest temperatures are -8 and 7 respectively.
Any number between -8 and 7 will be a possible temperature for Wednesday. 3 can be a possible temperature for Wednesday as 3 is between -8 and 7.
