The additive inverse of a number is that number with its sign changed.
The additive inverse of 5/8 is -5/8, so that is the value of <em>m</em>.
The sum of a number and its additive inverse is <em>zero</em>. (This is actually the definition of <em>additive inverse</em>.)
5/8 is found at 5/8 on the number line.
m is found at -5/8 on the number line.
"sum" is found at 0 on the number line.
I’m pretty sure the first one is y = 3x + 2 and the second one is y = -x + 4
The question has got numerous valuable information's that are required for getting to the desired answer. it is important to minutely read all the information's given in the question before going for solving.
It is already given in the qustion that after 17 minutes there is still 81% of the download reamining. This means that in 17 minutes the total download that took place is only 19%.
Based on this knowledge, the answer to the question can definitely be deduced.
So
The time taken for downloading 19 percent of the digital textbook = 17 minutes
Then
The time taken by the student for
downloading 100 percent of the digital text book = (17/19) * 100 minutes
= 1700/19 minutes
= 89.47 minutes
So at this rate the student will need 89.47 minutes to complete the downloading of the digital text book.
Answer:
The area of rectangle URST is 135 mm² ⇒ 3rd answer
Step-by-step explanation:
- Congruent rectangles have same lengths of sides, same measures
of angles and same areas and same perimeters
- Rectangle ABCD is congruent to rectangle URST
- The length of sides A B is 9 millimeters and the length of sides R S is
15 millimeters
- We need to find the area of rectangle URST
∵ Rectangle ABCD ≅ rectangle URST
∴ AB = UR , BC = RS , CD = ST , AD = UT
∵ AB = 9 millimeters
∴ UR = 9 millimeters
- The area of any rectangle = l × w, where l, w are its dimensions
- In rectangle URST
∵ UR = 9 millimeters
∵ RS = 15 millimeters
- Assume that UR = l and RS = w
∴ The area of rectangle URST = UR × RS
∴ The area of rectangle URST = 9 × 15 = 135 millimeters²
* <em>The area of rectangle URST is 135 mm²</em>
