Answer:
3xy2
Step-by-step explanation:
GCF is the largest factors which are common in two or more numbers.
We find the GCF of two or more number number by breaking each number into their factor and then observe which factors are common in the group and then we multiple the common number to get the GCF.
Lets understand this by an example
GCF of 24 and 36
factors of 12 = 2*2*2*3 , factors of 36 = 2*2*3*3
hence we see that 2,2 and 3 are common in 12 and 36 hence
GCF will be 2*2*3 = 12
Coming back to problem
given
Expression 1 is 3xy^2
factor of 3xy^2 = 3*x*y*y
Expression 2 is 42xy4
factor of 42xy4 = 2*3*7*x*y*y*y*y
common factor between the two expressions are
3, x, y , y
hence GCF will be = 3*x*y*y =3xy2 Answer
Answer:
75 in coupons.
250 in dividends.
profit of 600 - 425 = 175 from her stock investment.
her total income is 250 + 75 + 175 = 500.
if all of this is taxed at 10%, then her tax will be 500 * .1 = 50.
Answer:
Area of the base of the prism = 48cm²
Step-by-step explanation:
A rectangular prism has a rectangular base
Area of a rectangular base, A = length x width
A = 6cm x 8cm = 48cm²
Answer:
$76.5
Step-by-step explanation:
93.5÷5.5=17
17×4.50=76.5
Therefore the answer is 76.5.
Answer:
$4,116
Step-by-step explanation:
Worth of Mike's car at the start of 2014 = $12,000
If the car is said to depreciates every year by 30% = 30/100 = 0.3
The worth of the car at the start of 2017 is what we are to determine.
This means that the car depreciated by 30% (0.3) for 3 years since 2014 (2017 - 2014 = 3 yrs)
The worth at the start of 2017 would be calculated as follows:
12,000 × (1 - 0.3)³
= 12,000 × (0.7)³
= 12,000 × 0.343
= 4,116
Worth of the car at the start of 2017 would be $4,116
