550-300=250
one year: 250/70=25/7 which will be rounded up to 4
250*2-(4*2)=500-8=492
492+300=792
Which means that around 792 chicken turtles in the habitat 12 years after the initial release.
What is the whole question
Answer:
Cost of 45 screwdrivers will be = $900
Step-by-step explanation:
Last year 15 electric screwdrivers cost to the local hardware store = $300
So per screwdriver cost =
=
= $20
Now we have to calculate the cost of 45 screw drivers.
Since cost of 1 screwdriver = $20
So cost of 45 screwdrivers = 20×45 = $900
The answer is 91 toys sold, make
the number ab where a is the 10th digit and b is the first digit. The
value is 10a + b that can expressed as 10 (3) + 4 = 34
Let the price of each item: xy
10x + y
He accidentally reversed the
digits to: 10b + a toys sold at 10y + x rupees per toy. To get use the formula,
he sold 10a + b toys but thought he sold 10b + a toys. The number of toys that
he thought he left over was 72 items more than the actual amount of toys left
over. So he sold 72 more toys than he thought:
10a + b =10b + a +72
9a = 9b + 72
a = b + 8
The only numbers that could work
are a = 9 and b = 1 since a and b each have to be 1 digit numbers. He reversed
the digits and thought he sold 19 toys. So the actual number of toys sold was
10a + b = 10 (9) + 1 = 91 toys sold. By checking, he sold 91 – 19 = 72 toys
more than the amount that he though the sold. As a result, the number of toys
he thought he left over was 72 more than the actual amount left over as was
stated in the question.
