A student skipped a step when she tried to convert 15 hours to seconds, and she got the following incorrect result:

Answers

Answer 1

Answer: The easiest and systematic way of answering this type of problem is through dimensional analysis. First we need to note that each hour has 60 minutes. Each minute has 60 seconds. First multiply 15 hours with the factor 60 mins/ hour, canceling the unit hour. Then multiplying with the factor 60 sec/mins, to cancel the mins unit. You are now left with the unit of sec. The answer is 54, 000 seconds.

Answer 2

Thomas has $6.35 in dimes and quarters. The number of dimes is three more than three times the number of quarters. If q represents the number of quarters, then which of the following expressions represents the number of dimes that Thomas has? 3d + 3 3q + 3 6.35 - q 10(3q + 3)

Answers

3q+3 because if the dimes is 3x as many as the quarter and plus 3 then you would multiply the quarters by 3 then add 3 and that would give you the number of dimes

b) (2x- 5) (3x + 1)
c) (6x-5) (x + 1)
d) 6x + 1) (x - 5)

Answers

For the quadratic trinomial $ax^2+bx+c$ the following formula

$ax^2+bx+c=a(x-x_1)(x-x_2)$ , where $x_1, x_2$ are trinomial roots, holds.

1. For trinomial $6x^2 - 13x - 5$ find the roots:

2. The factoring form is

$6x^2-13x-5=6\left(x+(1)/(3)\right)\left(x-(5)/(2)\right) =(3x+1)(2x-5)$

Answer: correct option is B.

to FL and add
multiply first terms and multiply last terms and add and see if we get the middle term
example
(x+2)(2x-3)=2x^2+x-6x
2*2x+x*-3=4x-3x=x=middle term so

a. (2x+5)(3x-1)
2x*-1+5*3x=-2x+15x=13x, no we want -13x

b. (2x-5)(3x+1)
2x*1+-5*3x=2x-15x=-13x correct

answer is B

How many hundredths are in one tenth? Explain using pennies and dimes.

Answers

Answer:

11 ways

100 Pennies & 0 Dimes

90 Pennies & 1 Dimes

80 Pennies & 2 Dimes

70 Pennies & 3 Dimes

60 Pennies & 4 Dimes

50 Pennies & 5 Dimes

40 Pennies & 6 Dimes

30 Pennies & 7 Dimes

Step-by-step explanation:

Final answer:

There are 10 hundredths in one tenth. This can be understood by considering that a dime, representing one tenth of a dollar, is equivalent to 10 pennies, each penny representing one hundredth of a dollar.

Explanation:

In terms of decimals, one tenth is represented as 0.1 and a hundredth is represented as 0.01. Given this, there are 10 hundredths in one tenth (because 0.1 divided by 0.01 equals 10). To understand this using pennies and dimes, consider one dime (which represents one tenth of a dollar) and a penny (which represents one hundredth of a dollar). As there are 10 pennies in a dime, we can conclude that there are 10 hundredths in one tenth.
