B. 17.6
C. 21.79
D. 15.65
Answer:
18.84
Step-by-step explanation:
The formula for circumference is 2(pi)r, I think. The radius is 3. 3 times 2 is 6. 6 times 3.14 is around 18, I think.

Step-by-step explanation:
1 Evaluate the expression 2a + b - 3 when a=5 and b=2. Please click on "show your work" to set up the problem and show your work. Then, enter your answer in the box to the right. You must complete both of these steps.
Answer:
9
Step-by-step explanation:
From the question,
We are to evaluate the expression : 2a + b - 3 when a=5 and b=2.
We substitute 5 for a and 2 for b in the given expression
2a + b - 3
= 2(5) + 2 - 3
= 10 + 2 - 3
= 12 - 3
= 9

Answer:
Step-by-step explanation: This is going to be a long one. In order to find slope you need the formula which is m=y2-y1/x2-x1. Basically what this means is you have to look on each of those graphs and find the points. I’ll do number one as an example. The points are located at (2,1) and (0,-3). Plug these in into your formula as such. M= (-3 - 1) / (0 - 2) which equals 2. If you have questions let me know
What is the value of y in the solution to the system of equations?
One-thirdx + One-fourthy = 1
2x – 3y = –30
Answer:
y-value = 8
Step-by-step explanation:
1/3x + 1/4y = 1 is the same as 4/12x + 3/12y = 1
which is the same as (4x + 3y)/12 = 1
which is the same as 4x + 3y = 12
add both equations and the 'y' will cancel and you will have 6x = -18
x = -3
2(-3) - 3y = -30
-6 - 3y = -30
-3y = -24
y = 8
Answer:8
Step-by-step explanation:
The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.
Answer:
y = 9x/5 + 50
Step-by-step explanation:
We are represent the information as coordinate (x,y)
If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)
Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;
(150, 320)
Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope;
m = y2-y1/x2-x1
m = 320-230/150-100
m = 90/50
m = 9/5
Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c
230 = 9/5(100)+c
230 = 9(20)+c
230 = 180 + c
c = 230-180
c = 50
Get the required equation
y = mx+c
y = 9/5 x + 50
Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

the slope and y intercept of y=-8x
Answer:
m = -8
b = 0
Step-by-step explanation:
In slope intercept form [ y = mx + b ], m = slope and b = y-intercept.
We aren't given a b value, but we are given a m value which is -8.

t = 12r/(r+120)
t(r+120) = 120r
tr+120t = 120r
tr-120r = -120t
r(t-120) = -120t
r = -120t/(t-120)
r = 120t/(120-t)

10=95/2+4^2x
Please show step by step, I am having trouble with logarithms.
Answer:
x = [tex]-\frac{75}{32}[/tex]
Step-by-step explanation:
10 = [tex]\frac{95}{2}[/tex] + [tex]4^{2}[/tex] * x
10 = [tex]\frac{5 * 19 }{2}[/tex] + ([tex]2^{2}[/tex])²x
10 = [tex]\frac{5 * 19 }{2}[/tex] + [tex]2^{2*2}[/tex] * x
x = [tex]-\frac{75}{32}[/tex]

a college spends 40% of an individual's tuition on salaries and the remainder on other costs if they spend 1,800 on other costs how much is an individual's tuition?
Answer:
$3000
Step-by-step explanation:
If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.
To find the total tuition, divide 1800 by 0.6:
1800/0.6
= 3000
So, their tuition was $3000

The value of angle APA' is 90°.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have a point 'p' which is a fixed point.
Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.
The new triangle formed is triangle A'B'C'.
From the figure, we can clearly see that the angle APA' is a right-angle triangle.
m∠APA' = 90°
Thus, the value of angle APA' is 90°.
