How many times greater is the value of the 6 in 560,984 than the value of the 6 in 85,560?

Answers

Each place value is 10 times higher than the one below it. The 6 in 560,984 is 3 place values ahead of the 6 in 85,560, and 10*10*10=1000, so it is 1000 times greater

A cone has a diameter of 8 cm. and a height of 4cm. If the height doubles then the volume is: a) four times largerb) three times as large
c) Twice as large
d) The same

Answers

the answer is c
its because volume of cone isπr²h
given d=8cm i.e r= 4cm h= 4cm
by applying the formulae 22/7×4×4×4=201
if the height is doubled the
h=8cm r = 4cm
again by applyng the same formulae
22/7×4×4×8=402
thus we can conclude that
if the height is doubled then the volume will be doubled
i hope i helped u.

The answer is c.

As we know, volume of cone = 1/3 πr²h

As we can see from the equation, volume of cone is directly proportional to the height. Thus, as the height increases, volume also increases.

Solve the equation.
a² = 0.16

Answers

take the square root of both sides to solve and you get a= 0.4,-0.4

Walter buys a bus pass for $30. Every time he rides the bus, money is deducted from the value of the pass. He rode 12 times and $24 was deducted from the value of the pass. How much does each bus ride cost?

Answers

If Walter had $24 taken away for 12 bus rides, that means each bus ride cost him $2 — to find what one ride costs, divide 12 by 12 (=1). Then you must do the same to the cost: 24/12 = 2.

on a test, 1 point is given for each correct answer and 1 point is deducted for each incorrect answer. On the test Harold answered 34 items correctly and 6 items incorrectly. What two numbers can be used to find Harold's total score

Answers

Forgive me if I'm wrong, but here goes:

On Harold's test, he scores 34 points for his correct answers, and -6 points for incorrect answers. He would have gotten 28 points, but that's not the question.

34 is the first number, and I believe the next one is -6.
6 is negative because 1 point is deducted for each incorrect answer, which also means 1 point is subtracted for every incorrect answer. Because the question is asking for numbers and not an equation or expression, the subtraction is expressed as a negative symbol, hence negative six.
