Genrish500 [490]

Answer:

a)  eight and seven ninths minus three and four sixths

Step-by-step explanation:

The required result is 5\frac{6}{54}

a)

8\frac{7}{9} -3\frac{4}{6}\\\\=\frac{79}{9}  -\frac{22}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{474-198}{54} \\\\=\frac{276}{54}\\\\=5\frac{6}{54}

b)

6\frac{8}{9} -1\frac{5}{6}\\\\=\frac{62}{9}  -\frac{11}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{372-99}{54} \\\\=\frac{273}{54}\\\\=5\frac{3}{54}

c)

4\frac{1}{6} +1\frac{1}{9}\\\\=\frac{10}{9}  +\frac{25}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{60+225}{54} \\\\=\frac{285}{54}\\\\=5\frac{15 }{54}

d)

3\frac{3}{6} +2\frac{4}{9}\\\\=\frac{22}{9}  +\frac{21}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{132+189}{54} \\\\=\frac{321}{54}\\\\=5\frac{51 }{54}

Eight less than four times the number c is twenty.<br> What is the value of c?
olganol [36]

Answer:

c=7

Step-by-step explanation:

The problem says that 8 less than 4 times c is less than twenty, so we can first show 8 less than 20.

4c -( I did this because it said 4 times the number c)

Then, we show 8 less than that.

4c-8

It says it is twenty, and that means it equals twenty.

4c-8=20

Now we solve!

4c-8=20

   +8  +8

*we add 8 to both sides*

4c=28

*we divide both sides by 4 since we want to isolate c*

c=28/4

c=7

I hope this helped!

Y=-6x^2+100x-180
Hunter-Best [27]
In the figure we have the graphic of this equation. So, the vertex is the maximum of this function. This point means that the maximum <span>daily profit from soccer balls is:

</span>y = 236.67
<span>
And this happens when the </span><span>selling price of each soccer ball is:

</span>x = 8.33
<span>
So if you want to get the best daily profit, this is the price you must sell each soccer ball.</span>

Angelina deposits $3000 in a savings account on 1 January 2019, earning compound interest of 1.5% per year.
jekas [21]

The interest earned would be $481.62.

The total amount of money in her account would be $16,377.12.

<h3>Determining interest after 10 years </h3>

Interest = future value - amount deposited

$3000 (1.015)^10 = $3,481.62

Interest =  $3,481.62 - $3000 = $481.62

<h3>Determining the future value of the account.</h3>

 Future value of the lump sum = $3000 x (1.015)^11 = $3,533.85

Future value of the annuity = amount deposited x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r = [(1.015)^10 - 1] / 0.015 = 10.702722

Future value =  10.702722 x $1,200 = $12,843.27

Total future value =  $12,843.27 + $3,533.85 = $16,377.12

Use distributive law evaluate
Cerrena [4.2K]

Answer:

The distributive property allows you multiply a sum in parenthesis by multiplying each addend separately, then add the products.

Step-by-step explanation:

How to use the distributive law example.

2(x+4) = 16

To use the distributive law in this example multiply 3 by all terms in the parenthesis. Multiply 2 and x, then 2 and 4 to open the parenthesis.

2x+8=16

That is how you use the distributive law.

To continue solving, subtract 8 from both sides.

2x+8-8=16-8

2x=8

Divide 2 from both sides.

2x/2=8/2

x=4

Hope this helps!

If not, I am sorry.
