Answer:
26 ft and 46 ft.
Step-by-step explanation:
The prime factors of 42 are 2 * 3 * 7.
Possible lengths and widths are:
L = 7, W = 6 giving a perimeter of 2*7 + 2*6 = 26 ft.
L = 14 , W = 3 giving perimeter = 34 ft.
L = 21, W = 2 giving perimeter = 46 ft.
Answer: it is -1
Step-by-step explanation:
5*5x=25x
5*3=15
25x+15=-10
25x= -10-15
25x= -25
X=-25/25
= -1
Answer:
1kg = 1000g
400g = 0,4 kg
0,4 - 1
1 - n
multiply diagonally
0,4*n = 1
n=10/4=2,5
1:2,5 is correct answer
Step-by-step explanation:
Prime numbers: 2, 3, 5, 7.
There are 4 prime numbers and 10 possibilities, so the probability is 4/10 = 2/5 or 40%
Answer: A. 11 . 38 + 4 . 03
B. 10 + 5 . 41
D. 9 . 2 + 6 . 21
Step-by-step explanation:
Step 1
Compute the sum of the given options
a) 11 . 38 + 4 . 03 = 15.41
b) 10 + 5 . 41= 15.41
c) 12 . 38 + 2 . 93= 15.31
d) 9 . 2 + 6 . 21 =15.41
e) 7 . 54 + 6 . 87=14.41
Step 2
Eliminate the expressions that do not give a sum of 15.41 , we have
a) 11 . 38 + 4 . 03 = 15.41
b) 10 + 5 . 41= 15.41
d) 9 . 2 + 6 . 21 =15.41
Therefore, the expressions with sum of 15.41 are A, B and D
