The area of a large rectangular field is 12, 750 square yards. The with is 150 ft.
a. find the length of the field in yards.
b. what is the length of the field in feet?
c. what is the area of the field in square feet?
Answer:
Area of rectangular field = 12750 square yards
Width = 150 feet
<< Find the length of the field in yards. >>
Your conversion factor: 3 feet = 1 yard
Width = 150 feet = 150/3 = 50 yards
Therefore,
Area = 12750 = L(50)
where
L = length of field = 12750/50
L = 255 yards
<< What is the length of the field in feet? >>
L = 255 yards * 3 feet/yard
L = 765 feet
< .What is the area of the field in square feet? >>
Since there are 3 feet in 1 yard, then there are 9 sq ft in 1 sq yard. Therefore,12750 sq yards * 9 sq feet/sq yd = 114,750 sq feet

10x + 1 + 12x - 5 = 180 Find x
Answer:
x = 92/11
Step-by-step explanation:
10x + 1 + 12x - 5 = 180
*group the like terms*
(10x + 12x) + (1-5) = 180
*simplify*
22x - 4 = 180
*add four on both sides to cancel out -4*
+4. +4
*simplify*
22x = 184
*divide both sides by 22 to cancel out the quantity and solve for x*
÷22 ÷22
*simplify*
x = 92/11
Answer:
x = 92/11, x = 8.36 repeating the .36, or x = 8 4/11

1/8k + 80= 1/2k + 120= ?
I need some help pls
1/8k + 80 = 1/2k + 120
Step 1: Subtract 1/2k from both sides.
1/8k + 80 - 1/2k = 1/2k + 120 - 1/2k
-3/8k + 80 = 120
Step 2: Subtract 80 from both sides.
-3/8k + 80 - 80 = 120 - 80
-3/8k = 40
Step 3: Multiply both sides by 8/(-3).
(8/-3) x (-3/8k) = (8/-3) x (40)
Answer: k = -320/3 or −106.667
For the function H(t) = 3t - 5
Find when H(t) = 46
Answer:
t = 17
Step-by-step explanation:
Plug in 46 for H(t) into the above equation and solve for t.
46 = 3t - 5 (add 5 to both sides)
51 = 3t (divide both sides by 3 to isolate t)
17 = t or t = 17

Answer:
After 5 hours.
35 bacteria cells.
Step-by-step explanation:
Andy’s population is represented by [tex]B=6x+5.[/tex]
Samantha’s population is represented by [tex]B=2^x+3[/tex]
Where B represents the total population given the number of hours x.
We want to find at what hour will their population be the same. We are told to use graphing technology.
Graphing them, we will get the graphs below.
Graphically, their population will be the same where the two graphs intersect.
So, we can see that they intersect at (5, 35).
Therefore, after 5 hours, the total number of bacteria cells for both experiments will be the same.
And the total number of bacteria at that time will be 35 bacteria cell.

The value of cos (t) is - (24/25), as per the relation between the sine and cosine of an angle.
What is the relation between the sine and cosine of an angle?For any angle 'Ф', the relation between the sine and cosine of an angle is:
sin² (Ф) + cos² (Ф) = 1, when 0 < Ф < (π/2)
Given equation,
sin (t) = (7/25), for (π/2) < t < π
Here, 't' is in the second quadrant.
Therefore, sine is positive here.
However, cosine is negative there.
Therefore, the value of cos (t) is
= - √[1 - sin² (t)]
= - √[1 - (7/25)²]
= - √[1 - (49/625)]
= - √(576/625)
= - (24/25)

The sum of the measures of the angles of a triangle equals 180°. Write and solve an equation to find the measure of the missing angle.
Answer:
108.9
Step-by-step explanation:
30.3 + 40.8= 71.1
180 - 71.1= 108.9
The measure of unknown ∠m is equal to 108.9°.
What is triangle inequality theorem?According to the triangle inequality theorem the sum of the length of any two sides will always be greater than the third side. Mathematically -
(a + b) > c
Given is a triangle with its angle measurements.
We know that the sum of the angles of a triangle is equal to 180 degrees.
Therefore, we can write -
∠m + 30.3° + 40.8° = 180°
∠m = 180° - 71.1°
∠m = 108.9°
Therefore, the measure of unknown ∠m is equal to 108.9°.

Some number minus 11 is equal to the product of the number and 18.
Answer:
n - 11 = 18n
Step-by-step explanation:
n−11=18n
Step 1: Subtract 18n from both sides.
n−11−18n=18n−18n
−17n−11=0
Step 2: Add 11 to both sides.
−17n−11+11=0+11
−17n=11
Step 3: Divide both sides by -17.
−17n−17=11−17
n=−1117
Answer:
n = −11/17
