Hi there!

Angle CED would be the same as Angle M. This is because triangles ABC and EDC are congruent. Since these triangles are congruent, you can use CPCTC to determine that Angle CED is congruent to Angle CAB, which has the value of M.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

IF THERE IS A TEACHER out there please answer 6=4x+9y

miskamm [114]

Answer:

$y=-\frac{4}{9}x +\frac{2}{3}$

Step-by-step explanation:

I'm going to presume you want this linear equation in slope-intercept form, so start with:

$6=4x+9y$

Subtract $9y$ from both sides of the equation:

$-9y+6=4x$

Subtract $6$ from both sides of the equation:

$-9y=4x-6$

Divide both sides of the equation by the coefficient of $y$ , which is $-9$ :

$y=\frac{4}{-9}x +\frac{-6}{-9}$

Simplify:

$y=-\frac{4}{9}x +\frac{2}{3}$

Answer:

574

Step-by-step explanation:

To round a two-digit number to the nearest ten, simply increase it or decrease it to the nearest number that ends in 0: When a number ends in 1, 2, 3, or 4, bring it down; in other words, keep the tens digit the same and turn the ones digit into a 0

Martha is late for class, so she races her 75 kg body up a 4.0 meter flight of stairs in only 2.3 seconds. What is Martha’s powe

vovangra [49]

Answer:

$1.3\cdot 10^3\text{ J}$

Step-by-step explanation:

Power is defined by work over time. In physics, work can be defined as the energy transferred over from an applied force over some distance. As a formula:

$W=Fd$ , where F = force applied and d = distance that force is applied over.

*It is worth noting that F must be parallel to the distance travelled. If it is perpendicular, no work is done, and if it is at an angle, find the parallel component and use that for F.

In this case, the force applied must counter the force of gravity on Martha, which is given by $F_g=mg$ , where m = Martha's mass and g = gravitational constant 9.8 m/s/s. Therefore, $F_g=75\cdot 9.8=735\text{ N}$ . Since she raises her body 4.0 meters, the work done must be $W=Fd=735\cdot 4=2940\text{ J}$ .

Since power is equal to work over time and t = 2.3 seconds, we have:

$\displaystyle P=\frac{W}{t}=\frac{2940}{2.3}=\boxed{1278\text{ J}}\approx \boxed{1.3\cdot 10^3\text{ J}}$ (to two significant figures)
