Answer:

no you cant use these three ratios for any right triangle

Step-by-step explanation:

Ratios: 0.38, 0.93, 0.36

0.38 I \ 0.93 right triangle

I \

I_____\

0.36

so this means a^2 + b^2 = c^2 would be true if these ratio worked

(0.36)^2 + (0.38)^2 = (0.93)^2

0.1296 + 0.1444 = 0.8649 NOT TRUE

Match each set of points with the slope of the line formed by the ordered pairs.

Fynjy0 [20]

1) The slope of the point (0,0) and (2,1) is 1/2.

2) The slope of the point (0,-1) and (2,-5) is -2.

3) The slope of the point (0,7) and (2,4) is -3/2.

4) The points (-1,3) and (-1,-3) has No slope.

5) The slope of the point (1,-3) and (-1,-3) is zero.

<u>Step-by-step explanation:</u>

There are five set of points given in the question.

You need to find out the slope of the line formed by the points.

The formula used to find the slope of a line is given by,

Slope = $\frac{y2-y1}{x2-x1}$

1) The given points are (0,0) and (2,1)

(x1,y1) ⇒ (0,0)

(x2,y2) ⇒ (2,1)

Slope = $\frac{1-0}{2-0}$

⇒ 1/2 is the slope.

2) The given points are (0,-1) and (2,-5)

(x1,y1) ⇒ (0,-1)

(x2,y2) ⇒ (2,-5)

Slope = $\frac{-5+1}{2-0}$

⇒ $\frac{-4}{2}$

⇒ -2 is the slope.

3) The given points are (0,7) and (2,4)

(x1,y1) ⇒ (0,7)

(x2,y2) ⇒ (2,4)

Slope = $\frac{4-7}{2-0}$

⇒ -3/2 is the slope.

4) The given points are (-1,3) and (-1,-3)

(x1,y1) ⇒ (-1,3)

(x2,y2) ⇒ (-1,-3)

Slope = $\frac{-3-3}{-1+1}$

⇒ -6/0 (No slope)

If the denominator of a fraction is zero, the expression is not a legal fraction because it's overall value is undefined.

∴ There is no slope.

5) The given points are (1,-3) and (-1,-3)

(x1,y1) ⇒ (1,-3)

(x2,y2) ⇒ (-1,-3)

Slope = $\frac{-3+3}{-1-1}$

⇒ 0/-2

∴ The slope is zero.

The average of the first 3 weights was 14 pounds. The average of the next 7 was 4 pounds. What was the overall average of the we

miskamm [114]

Answer:

$Average = 10$

Step-by-step explanation:

Given

$First\ Three = 14$ --- Average

$Next\ Seven= 4$ --- Average

Required

Determine the overall average

Represent the sum of the first three with x.

So:

$\frac{x}{3} = 14$

Solve for x

$x = 14 * 3$

$x = 42$

Represent the sum of the next seven with y.

So:

$\frac{y}{7} = 4$

Solve for y

$y = 4 * 7$

$y = 28$

The overall average is calculated as thus:

$Average = \frac{x + y}{7}$

$Average = \frac{42 + 28}{7}$

$Average = \frac{70}{7}$

$Average = 10$

SOLVE Janet piano teacher charged $12.50 for a 30-minute lesson if Janet has a 4 lesson per month how much will she owe her pian

miskamm [114]

You would multiply 12.50 by 4 because thats how much each lesson is and you go 4 times a month. You then multiply this by 12 because there are 12 months in a year. The answer comes out to $600 a year. Hope this helps. XD
