What is the solution to the equation 3.6m − 2.7 = −1.8m?

Finger [1]

Answer:

Option B is correct

m = 0.5 is the solution to the equation

Step-by-step explanation:

Given the equation:

$3.6m-2.7= -1.8m$

Add 2.7 to both sides, we have;

$3.6m-2.7+2.7= -1.8m+2.7$

Simplify:

$3.6m = -1.8m+2.7$

Add 1.8 m to both sides we have;

$5.4m =2.7$

Divide both sides by 5.4 we have;

$m = \frac{1}{2} = 0.5$

⇒m = 0.5

Therefore, the solution for the given equation is, 0.5

Which does NOT represent the interior angle measures of a triangle?

lord [1]

Answer:A

Step-by-step explanation:

Interior angles of a triangle ALWAYS have to be equal to 180

The sum of A is 180, however, those angles wont work because they have to be more close to eachother for it to be possible

The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides

The diagram shows a 3 cm x 5 cm x 4 cm cuboid

Rainbow [258]

Answer:

a) The length of segment AC is approximately 5.83 centimeters.

b) The angle ACD is approximately 34.5º.

Step-by-step explanation:

a) Since $AB \perp BC$ , the length of segment $AC$ is determined by Pythagorean Theorem, that is:

$AC = \sqrt{(5\,cm)^{2}+(3\,cm)^{2}}$

$AC \approx 5.831\,cm$

The length of segment AC is approximately 5.831 centimeters.

b) Since $AB \perp BC \perp AD$ , the length of segment $AD$ is determined by this Pythagorean identity:

$AD = \sqrt{(3\,cm)^{2}+(5\,cm)^{2}+(4\,cm)^{2}}$

$AD \approx 7.071\,cm$

The angle ACD is determined by the following trigonometric expression:

$\cos C = \frac{AC}{CD}$

$\cos C = \frac{5.831\,cm}{7.071\,cm}$

$\cos C = 0.825$

$C = \cos^{-1} 0.825$

$C \approx 34.448^{\circ}$

The angle ACD is approximately 34.448º.

What are the points of intersection of -x^2+9x-3 and y=3x

ELEN [110]

Answer:

Easiest and fastest way is to graph both equations into a graphing calc and trace the graph to where they intersect.

Alternatively, you can use substitution to solve for your answer.
