What is the length of the longest side ?
Answers
Answer:
11 feet (Option C)
Step-by-step explanation:
Let the longer side be l and the shorter side be b.
We know that,
→ Perimeter of rectangle = 2 ( longer side + shorter side )
Here,
Perimeter of rectangle is 32 feet.→ 32 = 2 (l + b)
→ 32 = 2l + 2(5)
→ 32 = 2l + 10
→ 32 - 10 = 2l
→ 22 = 2l
→ [tex] \sf \dfrac{22}{2} [/tex] = l
→ 11 = l
→ 11 feet = longer side
[tex] \therefore [/tex] Length of the longer side is 11 feet.
The diameter of a circle is 16 in. Find its circumference in terms of \piπ.
Answers
Answer:
50.24
Step-by-step explanation:
The formula for solving circumference is 2 x pi x r
first the radius is 8 (divide 16 by 2 and get radius)
( pi can be 22/7 or 3.14. but I’m taking 3.14 )
second, we have all values, now we just have to substitute them!
Pi = 3.14
R = 8
so when we do 2x 3.14 x 8 = 50.24
I hope this helped!

At the Middleton School festival, a tent covers a rectangular space 30 1/2 yards long and 9 1/3 yards wide. What is the area, in square yards, covered by the tent?
Answers
Answer:
284 2/3 square yardsStep-by-step explanation:
Area of rectangle:
A = lwA = 30 1/2 * 9 1/3 = 61/2 * 28/3 = 854/ 3 = 284 2/3 square yardsAnswer:
284 ²/₃ square yards
Step-by-step explanation:
Area of a rectangle
Area = length × width
Given:
length = 30 ¹/₂ yardswidth = 9 ¹/₃ yardsSubstitute the given values into the formula and solve for area:
[tex]\begin{aligned}\sf Area & = \left(30+\dfrac{1}{2}\right) \times \left(9+\dfrac{1}{3}\right)\\\\ & = \dfrac{30 \times2+1}{2} \times \dfrac{9 \times 3+1}{3}\\\\ & = \dfrac{61}{2} \times \dfrac{28}{3}\\\\& = \dfrac{61 \times 28}{2 \times 3}\\\\ & = \dfrac{1708}{6}\\\\ & = \dfrac{1704+4}{6}\\\\ & = \dfrac{1704}{6}+\dfrac{4}{6}\\\\ & =284\: \frac{2}{3}\:\:\sf square\:yards\end{aligned}[/tex]
Therefore, the area covered by the tent is 284 ²/₃ square yards.

What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
For, game A:
Odd x odd= odd,odd x even= eveneven x even = evenNot fair
For game B,
Odd + odd = eveneven + even= evenodd+ even= oddAgain, unfair.
P (odd, odd)= 1/4
P(even, even)=1/4
P(odd, even)=1/2
Hence, none of the game is fair.

A rope that is 6 meters long will be cut into 24 pieces that are all of the same
length. What will be the length of each piece, in centimeters?
Answers
Answer: I would say 4 centimeters
Step-by-step explanation: Well if 24 divided by 6 equals 4 then I would say 4
Based on the length of the rope and the number of pieces it is to be cut into, the length of each piece will be 25 cm long.
First covert the length of the rope to centimeters:
= 6 x 100
= 600 cm
The length of each piece will be:
= Length of rope / Number of pieces
= 600 / 24
= 25 cm
In conclusion, each piece will be 25 cm long.

A ladder that is 14 feet long is placed against a building. The bottom of the ladder is 6 feet from the base of the building.
A right triangle with side length 6 feet, hypotenuse 14 feet, and side h.
In feet, how high up the side of the building is the top of the ladder? Round to the nearest tenth of a foot.
12.65
Answers
Answer:
12.6 ft
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
let h be height up the side of the building , then
h² + 6² = 14²
h² + 36 = 196 ( subtract 36 from both sides )
h² = 160 ( take the square root of both sides )
h = [tex]\sqrt{160}[/tex] ≈ 12.6 ft ( to the nearest tenth )
