Answer:
72 rods
Step-by-step explanation:
First, find the volume of each rod, using the formula V = [tex]\pi[/tex]r²h
Plug in pi, the radius, and height, and solve:
V = [tex]\pi[/tex]r²h
V = (3.14)(2²)(60)
V = (3.14)(4)(60)
V = 753.6
So, each rod has 753.6 cm³ of steel.
Divide 54,259.2 by this to find how many rods it will make:
54,259.2 / 753.6
= 72
So, it will make 72 rods.

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now just refer to the above ( also copy and paste the above on your computer some where so you have it always)
sin( D )= 28 / 53
sin( E ) = 45 / 53
cos(D) = 45 / 53
cos(E) = 28 / 53

Which of the following could be true if y ≤ -75?
Hello!
Lets go through each choice, and determine if it is correct.
So, the symbol ≤, means less than or equal to. So our answer must be less than -75 or -75 on the dot.
A: y = 75
Okay, so we can tell this one is wrong off the bat. 75 is much more than -75. (Make sure you notice the symbol!) So it cannot be equal to said answer. A is wrong.
B: y =-74
Another trick question! When you are in the negatives, less is more! So -74 is actually greater than -75. This is also incorrect!
C: y > -75
This one is straight forward. Our equation up top strictly says less than or equal too, while C says greater than. Incorrect!
D: y = -75
The last answer! We see that the symbol in our equation up top says less than or equal too, and y = -75 is equal. This is the correct answer.
Our correct answer is D: y = -75

What is the expression for k more than 8?
Answer:
k>8
Step-by-step explanation:
k more than 8 indicates that the value of k is larger than 8. So the inequality sign opens towards k and closes towards 8.

Shannon is purchasing a government bond with a par value of $800 and a price quote of 101.524%. What is the price of the bond?
Answer: $812.192
Step-by-step explanation:
The price of the bond will be gotten by multiplying the par value by the price quote. This will be:
Price of bond = Par value × Price quote
Price of bond = $800 × 101.524%
Price of bond = $800 × 1.01524
Price of bond = $812.192
Therefore, the price of the bond is $812.192.

Answer:
x = 23
Step-by-step explanation:
The measures of the angles in a triangle add up to equal 180
That being said we can create an equation to solve for x
180 = 2x + 3x + 1 + 3x - 5
Now we solve for x using basic algebra
step 1 combine like terms
2x + 3x + 3x = 8x
1 - 5 = -4
now we have 180 = 8x - 4
step 2 add 4 to each side
-4 + 4 cancels out
180 + 4 = 184
now we have 184 = 8x
step 3 divide each side by 8
8x/8=x
184/8=23
we're left with x = 23
What is the solution to this system of equations?
18x - y = - 42
y= (-43x+34)/20
Answer:
X=-2
Step-by-step explanation:
equation a)
-y=42+18x
equation b)
y= (-43x+34)/20
Solution
42+18x= (-43x+34)/20
20(42+18x)=-43x+34
840+360x = -43x+34
360x+43x=34-840
403x= -806
x= -(806/403)
x= -(2)
x= -2

This is ur answer....
B. (5×8) - 3Hope it helps!
Brainliest pls....
Follow me! ;)
Answer:
B
Step-by-step explanation:
Subtracting 3 from the product of 8 and 5 means that the 8 and 5 need to be multiplied first.
Brackets, in the order of operations, come before other operators, other than square root, square, and the like. In general, multiplication and division would be done before subtraction, so the bracket goes over 5 x 8 and not 8 - 3.

Restaurants A, B, C, and D lie on a circular lake. Restaurants A and Care near the
road. The angle between the two roads is 70°.
The dashed segments show the path of a boat which sails between the restaurants
and transports guests.
Answer:
10
Step-by-step explanation:
Angle α in the given problem comes to be 125°.
∠ATC =70°(given)
Suppose the center of the circle is O while both the tangents intersect at T.
As we know quadrilateral ATCO is a cyclic quadrilateral because a quadrilateral constructed by tangents, corresponding points of tangency, and the center of a circle is a cyclic quadrilateral.
What is a cyclic quadrilateral?A quadrilateral with all its vertices on the circumference of the circle is called a cyclic quadrilateral. The sum of opposite angles is always 180° in a cyclic quadrilateral.
So, ∠AOC = 180 - ∠ATC
∠AOC = 180 - 70
∠AOC = 110°
We know that angle made by an arc at the circumference is half of the angle made by the same arc on the center.
So, ∠ABC = 110/2 = 55°.
Quadrilateral ABCD is a cyclic quadrilateral
So, α =180- ∠ABC
α =180-55
α=125°
Therefore, angle α in the given problem comes to be 125°.

The angles surrounding the point p are 90 degrees
Then using the angle given, find the missing angles.
JPH = 90
HJP = 49
90+49 = 139
180 - 139 = 41
Therefore JHP = 41
HLP = HJP = 49
HLP = 49
KLP = 72
KLP + HLP = 72 + 49 = 121
Therefore, HLK = 121

Complete Question
After a special medicine is introduced into a petri dish containing a bacterial culture, the number of bacteria remaining in the dish decreases rapidly. The number of bacteria decays by a factor of 1/15, every 6.76minutes, and can be modeled by a function, N, which depends on the amount of time, t (in minutes). Before the medicine was introduced, there were 90,000 bacteria in the Petri dish. Write a function that models the number of bacteria t minutes since the medicine was introduced.
Answer:
Nt = 90,000 × e^t/15
Step-by-step explanation:
The function that models the number of bacteria t minutes since the medicine was introduced is written as
Nt = No×e^λt
Where:
No = The initial number of the bacteria after time t
Nt = The current number of the bacteria after time t
λ = Decay constant or factor
t = Time in years
From the question,
No = 90,000 bacteria
Nt = The current number of the bacteria after time t
λ = 1/15
t = Time in years
Therefore, our function is written as:
Nt = 90,000×e^1/15 × t
Nt = 90,000 × e^t/15
Answer:
90,000*(1/15)^t/6.7

Welcome for the answer. This answer is for good intentions only to report if necessary. Thank you have a great rest of your day.Value of x (2x+43) (2x-3)
Answer:
-46
Step-by-step explanation:
2x+43=2x-3
We simplify the equation to the form, which is simple to understand
2x+43=2x-3
We move all terms containing x to the left and all other terms to the right.
+2x-2x=-3-43
We simplify left and right side of the equation.
0x=-46
0=-46
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
