The true statements would be
A and B
Reason is that one side is 20ft long a rectangle has 2 sets of matching sides.
So we can say that 2 sides equal 20 feet each. Total being 40 feet
So we take each B and multiply them by 2 for the two sides it shall equal.
6*2=12
8*2=16
Add those numbers to the 40 and will give you the corresponding amount of fence is required.

Find the HCF and LCM of 306 and 54. Verify that HCF × LCM = Product of the two numbers.
Gala2k [10]
306=2*153=2*3*51=2*3*3*17
54=2*27=2*3*9=2*3*3*3,
so 306= 2*3*3*17, and 54 = 2*3*3*3
GCF we are looking for all factors that belong to both of these numbers, that are common for both numbers.
 306= 2*3*3*17, 
 54 = 2*3*3*3
GCF = 2*3*3

LCM should include all factors that belong as first as second numbers, and we take prime factor from the number that has maximum repetition of it
306 = 2*3*3*17
54=2*3*3*3
We can see 2 - one time, 3 - 3 times , and 17 - one time
LCM =2*3*3*3*17

Product of two numbers : 306*54=(2*3*3*17) * (2*3*3*3)= 2²*2⁵*17
HCF*LCM=(2*3*3)*(2*3*3*3*17)=2²*3⁵*17
So we can see that
 Product of two numbers = HCF*LCM=2²*3⁵*17

If you need you can calculate
 306= 2*3*3*17, 
 54 = 2*3*3*3
GCF = 2*3*3=18
LCM =2*3*3*3*17=918
GCF*LCM=18*918=16524
Product of 306*54= 16524

Marcus and his family are planning a vacation that involves horse back riding. Horseshoe Ranch charges a $12.95 ranch entrance f
madreJ [45]

Answer:

$57.8

Step-by-step explanation:

Horseshoe ranch charges $12.95 ranch entrance fee

$14.95 is paid per hour to rent the horse

Therefore since Mary is going to rent the horse for 3 hours then the total amount she will spend can be calculated as follows

= $12.95 + $14.95×3

= $12.95 + $44.85

=$57.8
