Answer:

The correct option is D.

Step-by-step explanation:

An an angle is called an obtuse angle if the measure of angle is lies between 90° and 180°. The angle θ is an obtuse angle if

$90^{\circ}$

The given statement is "An obtuse angle is an angle whose measure is greater than 90°."

It is an false statement, because all angles whose measure is more than 90°, are not an obtuse angle.

For example the angle 200° is more than 90° but not less than 180°, therefore the angle 200° is not an obtuse angle. The angle 180° is not an obtuse angle.

Therefore option D is correct.

D No, it is not. A straight angle has a measure greater than 90°, but it is not an obtuse angle.
The sentence should say: An obtuse angle is an angle whose measure is greater than 90° but less than 180°

55.5% repeating as a decimal

liberstina [14]

Answer:

0.555

Step-by-step explanation:

When you ask, "What is 55.5 as a decimal?", we assume you want to know what 55.5 percent is as a decimal. In other words, 55.5 percent converted to decimal.

First, we will tell you why it is useful to know 55.5 as a decimal.

Normally, to calculate 55.5 percent, you would multiply a number by 55.5 percent and then you would take the product of that and divide it by 100 to get the answer.

Instead, you can simply multiply a number by 55.5 as a decimal to get the answer.

55.5 percent means 55.5 per hundred. Therefore, to get 55.5 as a decimal, all you have to do is divide 55.5 by 100 like so:

55.5 ÷ 100 = 0.555

The point (2, –4) is reflected across the line y = –1. What are the coordinates of the image?

schepotkina [342]

ANSWER

The coordinates of the image are (2,2)

EXPLANATION

The mapping for a reflection across the line y=k is :

$(x,y)\to (x,2k-y)$

We want to find the image of the point (2,-4) after a reflection in the line y=-1.

In this case k=-1.

$(2, - 4)\to (2,2( - 1)- - 4)$

This simplifies to,

$(2, - 4)\to (2, - 2 + 4)$

$(2, - 4)\to (2, 2)$

Hence the image is (2,2)

I'm not sure how to solve please help

wel

Follow these step:
So you want to start with adding the 5 to the other side of the equation so it would become 8=g/4
Then you want to multiply each side by 4 so it becomes 32=g

The answer is g=34
I hope this helps :)
