Answer:

b = 15

Step-by-step explanation:

Solve for b:

4.8/ 1 7/9 = 1.2b/6 2/3

Cross multiply:

6 2/3 * 4.8 = 1.2b * 1 7/9

6 * 3 + 2/3 * 4.8 = 1.2b * 9 + 7/9

20/3 * 48/10 = 12b/10 * 16/9

20 * 4 = b * 16/3

5 = b * 1/3

b = 5 * 3

b = 15

The low temp for the day was 9 degrees. It was only 12 degrees above the all-time record low for Dallas.

Is this meant to be a question? If so, what are you asking. The all time low for Dallas would be -3 degrees if that's what you want to know.

Carpenters use a tool called a speed square to help them mark right angles . A speed square is a right triangle

Ronch [10]

Answer:

A. $Area = \frac{1}{2}(2x^2 - 2x - 24)$

B. $Area = 3.75 in^2$

Step-by-step explanation:

A. $Area = \frac{1}{2}bh$

Where,

$b = 2x + 6$

$h = x - 4$

Plug in the values to get a polynomial that represents the area of the tool

$Area = \frac{1}{2}(2x + 6)(x - 4)$

$Area = \frac{1}{2}(2x(x - 4) + 6(x - 4)$

$Area = \frac{1}{2}(2x^2 - 8x + 6x - 24)$

$Area = \frac{1}{2}(2x^2 - 2x - 24)$

B. To find area, when x = 4.5 in, plug in the value of x into the equation for the area of the tool.

$Area = \frac{1}{2}(2(4.5)2 - 2(4.5) - 24)$

$Area = \frac{1}{2}(2(20.25) - 9 - 24)$

$Area = \frac{1}{2}(40.5 - 9 - 24)$

$Area = \frac{1}{2}(7.5)$

$Area = 3.75 in^2$
