Answer:
The perimeter of the rectangle is 10.5p + 10.7q - 3.8r
Step-by-step explanation:
The perimeter of the triangle is calculated by adding the values of the three sides.
In this case, the values of the individual sides are expressed algebraically.
We can still add them, however, taking into consideration like terms.
Perimenter of triangle = (4.1p+4.4q) + (6.4p-5.1r) + (1.3r+6.3q)
Perimeter = 4.1p + 6.4p + 4.4q + 6.3q -5.1r + 1.3r
Now we have grouped them, we can add the different groups separately
Perimeter = 10.5p + 10.7q - 3.8r
Therefore, the perimeter of the rectangle is 10.5p + 10.7q - 3.8r
Find the area the sector. A. 38π in² B. 1083π4 in² C. 57π4 in² D. 1083π8 in²
Answer:
[tex]A=135.37\ \text{inch}^2[/tex]
Step-by-step explanation:
Given that,
Radius of circle, r = 19 inch
Angle with sector, [tex]\theta=135^{\circ}[/tex]
We need to find the area of the sector.
The formula is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{135}{360}\times \pi (19)^2\\\\A=135.37\ \text{inch}^2[/tex]
So, the area of the sector is [tex]135.37\ \text{inch}^2[/tex].

Help me please! Ray BD is the angle bisector.What is the value of x?
Answer:
x = 4
Step-by-step explanation:
An angle bisector divides an angle into two equal parts. This means that you can set the two parts equal to each other and solve for x.
8x + 35 = 11x + 23
(8x + 35) - 35 = (11x + 23) - 35
8x = 11x - 12
8x - 11 x = (11x - 12) - 11x
-3x = -12

The sum of twice a number and seven is 13. Find the number.
Answer:
The answer is 3Step-by-step explanation:
Let the number be x
The statement
twice a number is written as
2x
The sum of twice a number and seven is written as
2x + 7
The result is 13
So we have
2x + 7 = 13
Subtract 7 from both sides
That's
2x + 7 - 7 = 13 - 7
2x = 6
Divide both sides by 2
That's
[tex] \frac{2x}{2} = \frac{6}{2} [/tex]

a man earns $140 in a 5 day week. what is his pay in 3 days?
Answer:
$84
Step-by-step explanation:
divide 140 by the five days and you get 28 then you multiple it by the 3 days and you get $84
His pay for 3 days would be $84.
To find the man's pay for 3 days, we can use the concept of proportionality. Since the man earns $140 in a 5-day week, we can calculate his daily earnings by dividing the weekly earnings by the number of days in the week:
Daily earnings = Weekly earnings / Number of days in the week
Daily earnings = $140 / 5 days
Now, let's calculate the daily earnings:
Daily earnings = $140 / 5 days = $28 per day
Therefore, the man's pay for 3 days would be:
Pay for 3 days = Daily earnings * Number of days
Pay for 3 days = $28 * 3 days = $84
His pay for 3 days would be $84.

expand and simplify 3(2x-1) +2(2x+5)
Answer:
10x + 7
Step-by-step explanation:
First expand by distributing the 3 and the 2 on the outside of both parentheses:
3(2x-1) + 2(2x+5) becomes
(6x - 3) + (4x + 10)
Then combine like terms (6x + 4x and -3 + 10) to simplify:

The two interior angles on one lateral face of a pyramid-shaped
paperweight measure 35° each. What is the measure of the unknown
angle?
Answer:
Option (B)
Step-by-step explanation:
From the property of a triangle,
Sum of all interior angles of the triangle is 180°
By applying this property in the given triangle IHK,
m∠HIK + m∠IKH + m∠KHI = 180°
m∠HIK + 35° + 35° = 180°
m∠HIK = 180° - 70°
= 110°
Therefore, measure of the unknown angle of the given triangle is 110°.
Option (B) will be the answer.
Answer:
As eudora states: B).110 is the correct answer.

Answer:
b > 250/9 and w ≥ 0
Step-by-step explanation:
7/9 (b - 27) > 49/81
First, simplify both sides of the inequality:
7/9b - 21 > 49/81
Add 21 to both sides
7/9b - 21 +21 > 49/81 +21
Multiply both sides by 9/7
9/7 x 7/9b > 49/81 x 9/7
b > 1750/81
Simplify
b > 250/9
11w - 8w ≥ 14w
Simplify both sides once again
3w ≥ 14w
Subtract 14w from both sides
3w - 14w ≥ 14w - 14w
-11w ≥ 0
Divide both sides by -11w
w ≥ 0
Answer:
4. 7/9 (b - 27) > 49/81
=> 7/9b - 21 > 49/81
=> 7/9b - 21 > 7/9
=> 7/9b -21 + 21 > 7/9 + 21
=> 7/9b > 7/9 + 189/9
=> 7/9b > 196/9
=> 7/9b / 7/9 > 196/9 / 7/9
=> To divide fractions, take the reciprocal of the divisor fraction and then multiply.
=> b > 196/9 x 9/7
=> b > 1764 / 63
=> b > 28
4th answer is b > 28
5. This question doesn't make any sense.
=> 11w - 8w greater or equal to 14w
=> 3w greater or equal to 14w.
If we make "w" as any number, this equation will not come true as 14 is larger than 3.
This answer may be correct the equation is like:
3w is smaller or equal to 14w.
