Answer:

$25

Step-by-step explanation:

An = 10 + An-1

At the end of 4th week ; amount repaid = $55

A4 = 10 +

An = a + (n - 1)d

n = 4

A4 = 10 + (4 - 1)d

55 = 10 + 3d

55 - 10 = 3d

45 = 3d

d = 15

Hence, at the end of first week :

A1 = a + d

$10 + $15

= $25

How many groups of 3/4 are in each of the following questions?
marysya [2.9K]

Answer:

12 1/3

Step-by-step exp

First, you need to add up 11/4 and

6 1/2

11/ 4 + 6 1/2 = 11/4 + 13/2 = 37 / 4

To find how many 3/4 we have in 37/4, we simply dividw 37/4 by 3/4

37/4 ÷ 3/4

= 37/4 × 4/3 (4 will cancel out 4)

= 37/3

=12 1/3

Estimate 394/24 by first rounding each number so that it has only 1 nonzero digit.
larisa [96]

Answer:

48 million

Step-by-step explanation:

Since 48,000,000 has TWO non-zero numbers, not one, it can't be the

answer.

The largest digit in the given number is the ten-millions digit, so

you want to round to the nearest ten million, rather than the nearest

million.

47,859,600 rounds to 50,000,000, to one significant digit.

Normally, we would say "round to one significant digit," but you

probably have not seen that term. Your question means the same th

Help please!! i don’t understand this one!
12345 [234]

Answer:

  C, D

Step-by-step explanation:

This equation can be solved any of several ways. One that doesn't require much thought is using the quadratic formula.

For ax² +bx +c = 0, the solutions are ...

  x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

In the given equation, a=2, b=11, c=5, so this becomes ...

  x=\dfrac{-11\pm\sqrt{11^2-4\cdot2\cdot5}}{2\cdot2}=\dfrac{-11\pm\sqrt{81}}{4}\\\\x=\dfrac{-11\pm9}{4}=\left\{-\dfrac{20}{4},-\dfrac{2}{4}\right\}=\{-5,-\frac{1}{2}\}

The solutions are ...

  C. x = -5

  D. x = -1/2

_____

My personal favorite is using a graphing calculator. The solutions are the x-intercepts of the expression on the left. That is, where its value is zero, as the equation says.
