Mathematics
1 answer:
kiruha [24]3 years ago

Answer:

Complementary angles, adjacent angles

Step-by-step explanation:

Which relationships describe angles 1 and 2?

Options: Complementary angles, vertical angles, supplementary angles, adjacent angles

Angles 1 and 2 are opposite to the 90° angle. So, the angles' relationship to that angles is a vertical angle, meaning that the two add up to 90°.

Complementary angles add up to 90°, so this option is correct.

Vertical angles are the pairs of opposite angles formed by two intersecting lines. Because the two angles do not follow this definition, this option is incorrect.

Supplementary angles add up to 180°. However, we know that the two add up to 90°, so this option is incorrect.

Adjacent angles are angles that are next to each other, so this option is correct.

I hope this helps! Feel free to ask any questions!

Three of the following steps are used in writing a mixed number as an improper fraction. Which step does NOT belong?
QveST [7]
I don't see the steps, but the steps that I use are:
1. Multiply the denominator by the whole number 
2. Then you add the numerator to your sum.
3. The number that you just got by doing those steps is now going to be your numerator and your old denominator is going to stay your denominator.

Example:

2 2/3 
3*2=6
6+2=8
8/3 is your new answer.

Sliva [168]
The correct equation would be Y=1/2x+4 :)

This is true because both equations have the same slope therefore they are parallel and the equation above also includes point (-6,1).

As James bought his textbooks for classes one semester, he estimated the cost to the nearest ten dollars. He knew he could cover
TEA [102]

Answer:

$310

Step-by-step explanation:

The first step is to add the costs of the textbook together :

$68.41 + $105.35 + $72.49 + $59.91 = $306.16

In order to round off to the nearest ten dollars, look at the units figure, if the number is greater or equal to 5, add 1 to the ten figure. If this is not the case, add zero. Replace the unit digit with zero

The unit digit is greater than 6, so 1 is added to the tens digit. The amount becomes $310

Your skateboard ramp is 2 3/8 feet high. Your friends skateboard ramp is 2 2/5 feet high. Which skate board ramp is higher
natulia [17]
Hi,

To find out with ramp is higher we need to put given fractions in decimal form.

2 \frac{3}{8}  = 2.375 \\ 2 \frac{2}{5}  = 2.400

In this case friend's ramp is higher.

Hope this helps.
