Answer: HOPE THIS HELPED! :D ;P

Acute triangle

Step-by-step explanation:

90 degrees

less than it is acute

more than it is obtuse

90 degrees is right angle

so since 75, 75, 30 are all less than 90 degrees it’s an acute angle

Don’t really know what your question is but 4 laps times 3 miles is 12 laps. He’s got 3 more laps to finish his goal.

Please help this is due tomorrow

Lostsunrise [7]

$\sf \left(\dfrac{1}{7}\right)^3\ is\ basically\ like\ saying\ you're\ multiplying\ \dfrac{1}{7}\ by\ \dfrac{1}{7},\ three\ times.$

$\implies\ \sf \dfrac{1}{7}\ \times\ \dfrac{1}{7}\ \times\ \dfrac{1}{7}\\\\\\\implies\ \dfrac{1}{343}$

Therefore, (1/7)³ = 1/343, implying that the answer is option (D).

Hope it helps. :)

What is the slope of a perpendicular line 2x + y = 6<br><br> is answer -2

Firdavs [7]

Answer:

The slope that is perpendicular to the line will be:

$m_2=+\frac{1}{2}$

Step-by-step explanation:

Given the equation

$2x\:+\:y\:=\:6\:$

We know that

$y=mx+b$ is the slope-intercept form of a line where m is the slope and b is the y-intercept.

So, writing the equation in the slope-intercept form

$2x\:+\:y\:=\:6\:$

$\:y=-2x+6$

here

$m=-2$ ∵ $y=mx+b$

As we know that for perpendicular lines, one slope is the negative reciprocal of the other.

Therefore, the slope that is perpendicular to the line will be:

$m_2=+\frac{1}{2}$
