Answer:
192cm²
Step-by-step explanation:
The diagonal of the rectangle is expressed using the formula:
d = √l²+w²
l is the length
w is the width
Given d = 20
20 = √l²+w²
400 = l²+w² .... 1
Since the difference between the length and the width is 4cm, then;
l - w = 4 ... 2
l = 4 + w
Substitute equation 2 into 1;
400 = (4+w)²+w²
400 = 16 +8w + w² +w²
400 = 16 + 8w + 2w²
2w²+8w - 384 = 0
w²+4w - 192 = 0
w = -4±√4²-4(-192)/2
w = -4±√16+768/2
w = -4±28/2
w = -4+28/2
w = 24/2
w = 12
Since l = w+4
l = 12+4
l = 16
Area of the rectangle = 16 * 12
Area of the rectangle = 192cm²

What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
We have
P = a
B = 12
H = 13
Then
13² = a² + 12²
169 = a² + 144
a² = 169 – 144
a² = 25
a = 5
Then the correct option is D.

A bag contains eleven balls labeled 1 through 11. One ball will be randomly picked. What is the probability of picking a multiple of 3? Write your answer as a fraction in simplest form.
Answer:
3, 6, 9 (the multiples of three within 11)
3 out of 11 numbers are multiples of 3
so you have a 3 out of 11 probability to grab a multiple of three
3/11 is your answer
Step-by-step explanation:
Probability of picking a ball of multiple of 3 is equals to (3/11).
What is probability?
" Probability is a mathematical expression which represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
'B' represents the ball
Possible outcomes = { B₁, B₂, B₃, ...., B₁₀, B₁₁}
favourable outcomes multiple of 3 = { B₃, B₆, B₉}
Total number of outcomes= 11
Number of favourable outcomes = 3
Substitute the value in the formula we get,
Probability of picking ball multiple of 3 = ( 3 / 11)
Hence, probability of picking a ball of multiple of 3 is equals to (3/11).

Tim’s age is nine more than his sister, Jill. Twice his age added to twice Jill’s age is 330.
Answer:
jill age is 78 and tim's age is 87
Step-by-step explanation:
let jill age be x then, tim's age is 9+x
by the question,
2(9+x) + 2x = 330
or,18 + 2x + 2x = 330
or,4x = 330-18
or, x = 312÷4
x = 78
9+x= 9+78=87

Answer:
Step-by-step explanation:
so many isosceles triangles
y = 4 .. just by inspection.. we can see
SOH CAH TOA <= ask me about this if you don't get it
Cos(x) = Adj / Hyp
we don't know the Hyp this time so solve for that
Hyp = Adj / Cos(x)
Hyp = 4 / Cos(45)
Hyp = 4 / [tex]\sqrt{2}/2[/tex]
maybe you know.. but i'll just remind you to bring the fraction up from the denominator... invert and multiply
Hyp = 4 * 2/[tex]\sqrt{2}[/tex]
Hyp = 8/ [tex]\sqrt{2}[/tex]
also we are supposed to write as a decimal rounded to the nearest 10th
Hyp = 5.66
