Answer: 9cm

Step-by-step explanation:

7x10=70cmx^{2}

4(x)=4x

1.) 70+4x=106 (subtract 70 on both sides)

2.)4x=36 (divide 4 on both sides)

3.)x=9

               b)  70%

Step-by-step explanation:

a) There are 10 marbles.The red marbles are 7

                so that  7/10

                 then change to decimal 7/10=0.7

b) if we get percentage *100

        so,    7÷10*100%

What is the slope of the line below? If necessary, enter your answer as a
alisha [4.7K]

Step-by-step explanation:

Use formula to find the slope/gradient

\frac{y2 - y1}{x2 - x1}

(-5, -1) = (x1, y1)

(5, 11) = (x2, y2)

So,

=  \frac{11 - ( - 1)}{5 - ( - 5)}  \\  =  \frac{12}{10 }  \\  =  \frac{6}{5}

A leprechaun places a magic penny under a girl's pillow. The next night there are 2 magic pennies under her pillow. The followin
dezoksy [38]

Answer:

<u><em></em></u>

  • <u><em>32 days</em></u>

Explanation:

Simulate (build a table) the growing of the number of pennies for some nights to figure out the pattern:

First night:          1 penny = 2⁰

Second night:    1 × 2 pennies = 2¹

Third night:        2 × 2 = 2²

Fourth nigth:      2² × 2 = 2³

nth night:           2ⁿ⁻¹

You want 2ⁿ⁻¹ ≥ 2,000,000,000

Which you solve in this way:

  • 2ⁿ⁻¹  ≥ 2,000,000,000

  • 2ⁿ⁻¹ ≥ 2,000,000,000

  • n-1 log (2)  ≥ log (2,000,000,000)

  • n - 1  ≥ log (2,000,000,000) / log (2)

  • n - 1 ≥ 30.9

  • n ≥ 31.9

Since n is number of days, it is an integer number, so n ≥ 32.

Hence, she will have a total of more than $ 2 billion after 32 days.

You can prove that by calculating 2³² = 2,147,483,648.
