The width of a rectangle measures (2.5u+9.8)(2.5u+9.8) centimeters, and its length measures (1.5u+3.9)(1.5u+3.9) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Solution,
We have,
Width of rectangle, b = (2.5u+9.8) cm
Length of rectangle, l = (1.5u+3.9) cm
We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by:
Perimeter = 2(l+b)
P = 2[(2.5u+9.8)+(1.5u+3.9)]
Collecting like terms
P = 2[(2.5u+1.5u)+(9.8+3.9)]
P=2(4u+13.7)
⇒ P = 8u+27.4
So, the expression for the perimeter of the rectangle is (8u+27.4) cm.

Sophie went to the lake with her family. First, they spent 1 1 4 hours fishing. Then, they spent twice as much time swimming. How much time did they spend fishing and swimming in all?
Answer:
The total time spent on both fishing and swimming is 3 3/4 hours
Step-by-step explanation:
Here, we are interested in knowing the total time spent on fishing and swimming.
From the question, we are made to know that the time spent fishing is 1 1/4 hours or simply 5/4 hours.
Then they spent two times of this time swimming.
The time spent swimming is thus 5/4 * 2 = 5/2 hours
So the total time spent on both swimming and fishing will be;
5/4 hours + 5/2 hours = (5 + 10)/4 = 15/4 = 3 3/4 hours

-4c+25+c=3c+79
Answer:
c = -9
Step-by-step explanation:
- 4c + 25 + c = 3c + 79 Combine like terms.
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c + 3c + 25 = 3c + 3c + 79
25 = 6c + 79
25 - 79 = 6c + 79 - 79
- 54 = 6c
-54/6 = 6c/6
-54/6 = c
-9 = c
There aren't 2 answers, you could have 2 answers if one of the c's was squared. Here is another way to do the math.
- 4c + 25 + c = 3c + 79
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c - 3c + 25 = 3c - 3c + 79
- 6c + 25 = 79
- 6c + 25 - 25 = 79 - 25
- 6c = 54
- 6c/- 6 = 54/- 6
c = 54/- 6
c = - 9
Answer:
-9 = c
Step-by-step explanation:
-4c+25+c=3c+79
-3c +25 =3c+79
25 = 6c +79
-54=6c
-54/6 = c
-9 = c

Anusha is walking on a hiking trail at a rate of Three-fourths miles in One-fourth hour. At this rate, how far will Anusha walk in an hour?
Answer:
Step-by-step explanation:
3/4 + 3/4 + 3/4 + 3/4 = 12/4 = 3. She will walk 3 miles in an hour.
The distance that Anusha covered in one hour is 3 miles
If Anusha is walking on a hiking trail at a rate of three-fourths miles in One-fourth hour, this is expressed as:
3/4 miles = 1/4 hours
We need to get the rate of Aisha that is the distance traveled in an hour
x = 1 hour
Divide both expressions
3/4x = 1/4
Cross multiply
4x = 3 * 4
4x = 12
x = 12/4
x = 3
Hence the distance that Anusha covered in one hour is 3 miles

Simplify 1,999,999 with an exponent of 0
The value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰
Before we can simplify with an exponent of zero, first we must understand that any number raised to the power of zero gives 1. Hence:
1,999,999 = 1,999,999 × 1
Since 1 can be expressed as 10⁰, the value becomes:
1,999,999 = 1,999,999 × 10⁰
Hence the value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰

I have 5digits My name is worth 90,000 my two is worth 2 thousand one of my sevens is worth 70 the other is worth 10 times as much my other digit is a six what number am I
Answer:
92776
Step-by-step explanation:
From the given question,
The analysis of the given question can be computed as follows:
I have 5 digits
My name is worth 90000
my two is worth 2000
one of my seven is worth 70
and the other is worth 10 times
as much i.e 10× 70 = 700 700
my other digit is six 6
What number am I?
So, we are expected to look for the summation of all the numbers
i.e 90000 + 2000 + 70 + 700 + 6
= 92776
Thus, the number is 92776
HELPPP HELPP!! WHAT IS THE VALUE OF X AND W???
Answer:
w = 42
x = 29
Step-by-step explanation:
We know that w + 138 must equal 180, so we get 42 for w. Then we know that 19 + x + 2 = 90, and w = 42. So if we add 42 + 19, and subtract that from 90, we get 29. Hope this helps!

Answer:

Step-by-step explanation:
The covers ( there are 2) are
2* .9 mm = 1.8 mm
Depending on how they are defining pages
If they are defining pages as the number of papers
400 pages at .13 =
400 *.13 = 52 mm
total = 2 covers + 400 pages
= 1.8 + 52
53.8 mm
If they are defining pages as the page numbers
Each page number is on the front and back so 400/2 = 200 pieces of paper
200 pages at .13 =
200 *.13 = 26 mm
total = 2 covers + 400 pages
= 1.8 + 26
27.8 mm
Answer:
52.8 mm thick
Step-by-step explanation:
0.9mm X 2mm90 = 1.8 mm
0.13mm X 400mm = 52 mm
1.8mm + 52mm = 53.8 mm

Round to the nearest 1 kilometer. A 2-column table with 3 rows titled Total Distance Andrea Ran (kilometers). Column 1 has entries March, April, May. Column 2 has entries 48.7, 31.2, 35.66.
Answer:
March=49
April=31
May=36
Andrea ran about 116 km
this is about 4 km less than last year
Step-by-step explanation:
I got it right :))
Andrea ran 4 km extra last year if, and the total distance run this year is 120 km, The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
What is subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given:
Total distance run this year = 120 km,
The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
Calculate the total distance = 48.7 + 31.2 + 35.66
The total distance this year = 115.56 or 116 km
Calculate the difference as shown below,
Distance = 120 - 116 = 4 km,
Thus, she ran 4 km extra last year.

Answer:
y=-2x-1
Step-by-step explanation:
first take 2 points from the graph to find m ( linear equation y=mx+b)
(-1,1) and (-2,3)
m=y2-y1/x2-x1
m=3-(1)/-2+1
m=2/-1
m=-2
now find b at point -1,1
y=-2 x+b
1=-2(-1)+b
b+2=1
b=1-2 ⇒ b=-1
y=-2 x -1
