Answer:
a) The formula for the area of a circle
Step-by-step explanation:
The formula for the area of a circle is
A = πr²
π is an irrational number and, no matter what value you use for r, the area will be an irrational number,
b) is wrong. A = ½(a + b)h.
c) is wrong. A = ½bh.
d) is wrong. A = bh.
All measurements are rational numbers, so the areas will be rational numbers.
No the product will be less than 9/10.
This can be easily seen if the fractions are converted into decimals.
The decimal form of the product of 7/8 and 9/10 is 0.867 while the decimal form of 9/10 is 0.9. Therefore, the product of 7/8 and 9/10 is not greater than 9/10
Answer:
$5.08
Step-by-step explanation:
Step one:
given data
We are told that a credit card company applies a 6% fee on all transactions under $10
since the cost of coffee bellow $10 that is $4.80, the 6% fee is applicable
so
=6% of 4.80
=6/100*4.80
=0.06*4.8
=$0.288
Step two:
the total fee will be
=0.288+4.80
= $5.08
