Answer:

A. Obtuse

Step-by-step explanation:

Well we can cross out C and D just by looking at the triangle because the triangle is not equal and there is no right angle.

Also it is not B an acute because not all the angles are acute.

Hence, the answer is A. Obtuse

Answer:

$\boxed{\mathrm{A}}$

Step-by-step explanation:

An obtuse triangle is a triangle with one obtuse angle and two acute angles.

An obtuse angle is an angle greater than 90 degrees.

An acute angle is an angle less than 90 degrees.

Angle C is an obtuse angle, it is greater than a right angle or 90 degrees.

Angles B and A are acute angles, they are less than a right angle or 90 degrees.

A square technology chip has an area of 25 square centimeters how long is each side of the chip

grigory [225]

ANSWER

Each side of the chip is 5 centimeters long.

EXPLANATION

The chip is in the form of a square.

The formula for finding the area of a square is

$Area=l^2$

We were given in the question that, the area is 25 square centimeters. This means that,

$25=l^2$

We take the square root of both sides to get,

$\sqrt{25}=l$

$\Rightarrow 5=l$

Hence the length of the square technology chip is 5 centimeters

The monthly cost of driving a car depends on the number of miles driven. Lynn found that in May her driving cost was $380 for 48

andrezito [222]

Answer:

$y=0.2x+284$

Step-by-step explanation:

Let x be the distance driven, d-distance and C our constant.

Our information can be presented as:

$y=mx+c\\\\450=830x+C\ \ \ \ \ \ \ \ \ eqtn 1\\\\380=480x+C\ \ \ \ \ \ \ \ \ eqtn 2$

#Subtracting equation 2 from 1:

$70=350x\\x=0.2$

Hence the fixed cost per mile driven, $x$ is $0.20

To find the constant, $C$ we substitute $x$ in any of the equations:

$450=830x+C\ \ \ \ \ \ \ X=0.2\\\therefore C=450-830\times0.2\\=284$

Now, substituting our values in the linear equation:

$y=0.2x+284$ #y=cost of driving, x=distance driven

Hence the linear equation for the cost of driving is y+0.2x+284
