Answer:

x=48

Step-by-step explanation:a triangle must= 180 so you take 180-(85+47) and you get 48 for your last angle

Answer:

Step-by-step explanation:

The sum of angles of a triangle is 180

<V + <P + <M = 180

47+85+x = 180

132 +x = 180

Subtract 132 from each side

132-132+x = 180-132

x =48

VladimirAG [237]

The maximum number is 33. $0.25 multiplied by 4 is $1.00. If you multiply $1.00 by 8, the result is $8.00. If you multiply 8 by 4, since the number of quarters equivalent to $1.00 is 4, the result is 32. The remaining number is 0.45. You can only add 1 more quarter. 32+1=33. Therefore, the answer is 33.

Sue buys 5 pieces of fabric.Each piece is 1 7/10 yards long.What is the total length of the fabric she buys?One yard of the fabr

irina [24]

Answer:

The total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .

Step-by-step explanation:

As given

Sue buys 5 pieces of fabric.

$Each\ piece\ is\ 1 \frac{7}{10}\ yards\ long.$

i.e

$Each\ piece\ is\ \frac{17}{10}\ yards\ long.$

$Total\ length\ of\ fabric\ sue\ buys = \frac{5\times 17}{10}\ yards$

$Total\ length\ of\ fabric\ sue\ buys = \frac{85}{10}\ yards$

In the decimal form

Total length of fabric sue buys = 8.5 yards

As given

One yard of the fabric costs $5

$Total\ cost\ of\ fabric\ sue\ buys = 8.5\times 5$

= $ 42.5

Therefore the total length of fabric sue buys is 8.5 yards and total cost of the fabric is $42.5 .

What is the equation in slope-intercept form of the line that passes through the points (−26, −11) and (39, 34)?

Scrat [10]

The equation in slope-intercept form of the line passing through the given points is: C. $y = \frac{9}{13}x + 7$

<u>Given the following points:</u>

Points on the x-axis = (-26, 39)

Points on the y-axis = (-11, 34)

To find the equation in slope-intercept form of the line passing through the given points:

Mathematically, the equation of slope is calculated by using this:

$Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}$

Substituting the given points, we have:

$Slope. \;m = \frac{34 - [-11]}{39 - (-26)}\\\\Slope. \;m = \frac{34\; + \;11}{39 \;+ \; 26}\\\\Slope. \;m = \frac{45}{65}\\\\Slope. \;m = \frac{9}{13}$

The standard form of an equation of line is given by the formula;

$y = mx + b$

Where:

x and y are the points.

m is the slope.

b is the intercept.

We would find the intercept:

$-11 = \frac{9}{13}(-26) + b\\\\ -11 = -18 + b\\\\b = -11 + 18$

Intercept, b = 7

The equation in slope-intercept form of the line is:

$y = \frac{9}{13}x + 7$
