Area = side * side
Area of the square = 6 1/9 * 6/1/9
= 36 1/81
Answer:
mATHeMaTics is Very FUN
Step-by-step explanation:
When coding the word OUCH using the Bacon's code alphabet with binary numbers we have:
O=01110
U=10100
C=00010
H=00111
Following the rule of lowercase and uppercase letters in the dummy message we will have:
O U C H
0 1 1 1 0 1 0 1 0 0 0 0 0 1 0 0 0 1 1 1
m A T H e M a T i c s i s V e r y F U N
From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844

Answer:
b= 26
Step-by-step explanation:
there are 2 triangles
area of the right angles triangle
1/2bh= 1/2 x3 x4 = 6cm²
for the next triangle we use pythagoras theorem to calculate the height
3²+4² = h² = 9+16 = 25
h = √25 =5
1/2bh = 1/2 x 5 x8 = 20
adding the two areas will give the area of the figure = 20 + 6 = 26
Answer:
5 years ago
Let Kelly's age be x
Jake's age is 4x
5 years later
Kelly's age is x + 5
Jake's age is 4x+5
The sum of both their ages is 60. The equation will be
x + 5 + 4x + 5 = 60
5x + 10 = 60
5x = 60 - 10
x = 50/5 = 10
So Kelly is (10 + 5) 15 years old.
Jake is (4*10 + 5) = 45 years old
