For problems like this we can use algebra to help us, the farenheight 6 hours ago was:
 (2xt)-6=-20
We have to balance the sides out, first we minus 6
2xt=-26
Now we can divide by 2
t=-13

We now know the temperature 6 hours ago was -13

A coffee shop sold 7 cups,3 pints, and 9 quarts of coffee. Express the number of cups of coffee sold in base 2
sweet-ann [11.9K]

Answer:

The total number of cups of coffee sold are 51 which can be expressed in base 2 as 110011.

Step-by-step explanation:

Considering the following information

  • 1 cup = 1 cup
  • 7 pints = 14 cups      ∵ 1 pint = 2 cups
  • 9 quarts = 36 cups    ∵ 1 quart = 4 cups

So, total number of cups will be = 51 cups

Converting 51 to the base 2

Divide  51 by 2 by repeatedly and observe remainder

\frac{51}{2}=25\quad \mathrm{Remainder}\quad \:1

\frac{25}{2}=12\quad \mathrm{Remainder}\quad \:1

\frac{12}{2}=6\quad \mathrm{Remainder}\quad \:0

\frac{6}{2}=3\quad \mathrm{Remainder}\quad \:0

\frac{3}{2}=1\quad \mathrm{Remainder}\quad \:1

\frac{1}{2}=0\quad \mathrm{Remainder}\quad \:1

Read and observe the remainder from top to bottom would yield 110011.

Therefore, the total number of cups of coffee sold are 51 which can be expressed in base 2 as 110011.

For every 1 cup of blue paint, \frac{10}{4} cups of red paint are needed

For every 1 cup of red paint, \frac{4}{10} cup of blue paint is needed

For every 4 cups of red paint, \frac{16}{10} cups of blue paint are needed

<em><u>Solution:</u></em>

Given that, there are 3 1/3 red cups of paint for every 1 1/3 cups of blue paint

Therefore, ratio is

Red : blue = 3\frac{1}{3} : 1\frac{1}{3}\\\\Red : blue = \frac{10}{3} : \frac{4}{3}

<h3><u>For every 1 cup of blue paint, ___ cups of red paint are needed</u></h3>

Let "x" be the cups of red paint needed

Then we get,

\frac{10}{3} : \frac{4}{3}\\\\x : 1

This forms a proportion

1 \times \frac{10}{3} = \frac{4}{3} \times x\\\\x = \frac{10}{4}

Therefore, 10/4 cups of red are needed for 1 cup of blue

<h3><u>For every 1 cup of red paint, ___ cup of blue paint is needed</u></h3>

Let "x" be the cups of blue paint needed

Then, we get

\frac{10}{3} : \frac{4}{3}\\\\1 : x

This forms a proportion

\frac{10}{3} \times x = \frac{4}{3} \times 1\\\\x = \frac{4}{10}

Thus, 4/10 cups of blue are needed for 1 cup of red paint

<h3><u>For every 4 cups of red paint,___ cups of blue paint are needed</u></h3>

Let "x" be the cups of blue paint needed

Then, we get

\frac{10}{3} : \frac{4}{3}\\\\4 : x

This forms a proportion

\frac{10}{3} \times x = \frac{4}{3} \times 4\\\\x = \frac{16}{10}

Thus 16/10 cups of blue paint are needed for every 4 cups of red paint
