Answer:

The measure of angle 2 is 110 degrees

Step-by-step explanation:

Step 1: Find the value of x

Since angle 1 and angle 2 are complimentary, that means they add up to 180.

2x + 3x + 5 = 180

Step 2: Solve for x

2x + 3x + 5 = 180

5x + 5 - 5 = 180 - 5

5x / 5 = 175 / 5

x = 35

Step 3: Find the measure of angle 2

m<2 = 3x + 5

m<2 = 3(35) + 5

m<2 = 110

Answer: The measure of angle 2 is 110 degrees

Lauren says that -3.5 is greater than -3 1/3. Do you agree? Explain.

kirza4 [7]

Answer:

$-3\frac{1}{2}$

Step-by-step explanation:

-3.5 means -(3 + $\frac{1}{2}$ )

In other words, -3.5 = $-3\frac{1}{2}$

When we draw two numbers $-3\frac{1}{3}$ and $-3\frac{1}{2}$ on a number line, $-3\frac{1}{2}$ comes first from left to right.

We know that all the numbers on a number line from left to right are in increasing order.

Therefore, $-3\frac{1}{2}$ is smaller than $-3\frac{1}{3}$ .

$-3\frac{1}{2}$

Lauren is not correct.

Is that not right? or am I just wrong cause it says that it is not right please help

RideAnS [48]

Answer:

98 cm²

Step-by-step explanation:

The area of a circle is:

$A=\pi r^2$

A semicircle is half a circle therefore the area of a semicircle would be:

$A=\frac{1}{2}\pi r^2$

We can plug in the given values into the equation:

$A=\frac{1}{2}*3.142*(7.9)^2\\A=\frac{1}{2}*3.142*62.41\\A=\frac{1}{2}*196.09222 \\A=98.04611$

We need to round to TWO sigfigs meaning...

$A=98 \ cm^2$

Sigfig rules:

Nonzero numbers are significant

Trailing zeros are significant (only if there is a decimal point)

Any sandwiched zero is signification (Ex: 405 --> 3 sigfigs)
