Answer:
2 x 2 x 2 x 5
Step-by-step explanation:
The first few prime numbers: {2, 3, 5, 7, 11, 13, 17, 19}
One way to start is to divide by the first prime until you can't do that any more, then try the next prime and so on until all the numbers in your list are prime.
40 = 2(20) divide 20 by 2 again
40 = 2(2)(10) divide 10 by 2 again
40 = 2(2)(2)(5) stop--all factors are prime.
Answer:
£5650
Step-by-step explanation:
The money max invested in the saving bond = x
After one year the intrest will be 2% of x
Amount = £5763
Amount = Principcal + Interest
= £5763 = x + 2% multiplied x
£5763 = x + 2x/100
= 50x/50 + x/50 = 5763
= 51x/50 = £5763
51x = 5763x50
51x = 288, 150
x = 288,150/51
x = 5650
So the money max invested = £5650
Answer:
Base: 8cm. Height: 21cm
Step-by-step explanation:
We know that the base of a rectangle is 13 cm. longer than the height and the perimeter is 58 cm. Here is how we would set up the problem:
2x+2(x+13)= 2x + 2x + 26 = 4x + 26 = 58 (now we use the distributive property:
4x + 26 = 58
-26 -26
4x = 32
So, the base is 8 cm.
Now it's time to find the height.
So, we know the base (in total) is 16 cm. Now we do 58-16=42. Now we divide 42 divided by 2 = 21 cm.
