Answer 1
Answer: C=a/2=8/2=4b=8. 1.7/2=6.8p=4+4+6.8+6.8=21.6m
Answer 2
Answer:

The perimeter of the rectangle is 21.6 m

Further explanation

To solve the above questions, we need to recall some of the formulas as follows:

Area of Square = (Length of Side)²

Perimeter of Square = 4 × (Length of Side)

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Rhombus = 4 × ( Length of Side )

Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )

Let us now tackle the problem !

Given:

Length of Diagonal = d = 8 m

Angle Between Diagonal and Width = θ = 60°

Unknown:

Perimeter = ?

Solution:

See the picture in the attachment ,

\sin \theta = (BC)/(AC)

\sin 60^o = (BC)/(8)

(1)/(2) √(3) = (BC)/(8)

BC = 8 * (1)/(2) √(3)

BC = 4 √(3)

BC = 4(1.7)

\boxed {BC = 6.8 ~ m}

\cos \theta = (AB)/(AC)

\cos 60^o = (AB)/(8)

(1)/(2) = (AB)/(8)

AB = 8 * (1)/(2)

\boxed {AB = 4 ~ m}

Perimeter ~ = 2 ( AB + BC )

Perimeter ~ = 2 ( 4 + 6.8 )

Perimeter ~ = 2 ( 10.8 )

\large {\boxed {Perimeter ~ = 21.6 ~ m} }

What is greater , 42,000 mg or 24 g?

Answers

mg=miligrams=1/1000 gram
so conversion factor is
1g/1000mg
mulriply 42,000mg by 1g/1000mg
units cancel and you are left with
42g
42 g and 24 g
42 is greater than 24g so


42,000 mg is greater
42000 mg is greater

How many sixties are in 244?

Answers

just divide 244 by 60
244/60=4.06666667 anyway you only need 2 decimal place so it would be 4.06
but 60 goes in 244 4 times with the decimal
Just divide it on a calculator and you get: 4.06666667

1. The mode is C. 18
2. The median is B. 16
3. The mean is D. 14.25
4. The median is 2.3
5. The mean is 18
1) the mode is the number that repeats the most in a given set of numbers, so the answer would be c, 18
2) the median is b, 16 (if you put the numbers in chronological order, there are two middle numbers, to get the median you have to average those two numbers)
3) the mean is d, 14.25 (add all the numbers up and divide by the amount of numbers that you have [if you have 5 numbers, you divide by 5])
4) the median is 2.3
5) the mean is 18

The orange triangle's area is 30 because 1/2 times 6 times 10 is 30.The blue triangle's area is 30 because the right side is 6 for base because the orange triangle base is 6 and it aglines with the blue one so the right side blue triangle base is 6 times 10 times 1/2 equals 30 and the 2 left over for base of blue triangle's left side times 10 is 20  times 1/2 equals 10 so 10 plus 30 plus 30 equals 60 so your answer is 60.
