Step-by-step explanation:
Circumference of a circle = πd
d is the diameter of the circle
Let us assume the diameter to be 1.8cm
Substitute into the formula;
C = 1.8π
C = 1.8(3.14)
C = 5.652 cm
Hence the circumference of the circle is 5.652cm

A wire is first bent into the shape of a triangle. Each side of the triangle is long. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?
Answer:
18 inStep-by-step explanation:
Here is the complete question.
A wire is first bent into the shape of a triangle. Each side of the triangle is 24in long. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?
A triangle have 3 sides. If each sides is 24in long, the perimeter of the triangle will be:
P = s1 + s2 + s3
P = 24in + 24in + 24in
P = 72in
If the same length of wire is unbent and reshape into a square, this means:
Perimeter of the triangle = Perimeter of the square
Perimeter of the square = 72in
To get the length of a side of a square, we will use the formula:
Perimeter of a square = 4L
72 = 4L
L = 72/4
L = 18in
Hence the length of a side of the square will be 18in.

Plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3:00 PM. When is the next time the stations will play the song at the same time?
Answer:
4.12 PM
Step-by-step explanation:
Radio station 1 : Plays the song every 18 minutes
Radio station 2 : plays the song every 24 minutes
Both stations play the song at 3:00 PM.
When is the next time the stations will play the song at the same time?
Find the lowest common multiple of 18 and 24
18 : 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270
24 : 48, 72, 96, 120, 144, 168, 192, 216
The lowest common multiple of 18 minutes and 24 minutes is 72 minutes
72 minutes = 1 hour 12 minutes
Add 1 hour 12 minutes to 3:00 PM to know when both radio station will play the song at the same time
= 3.00 PM + 1 hour 12 minutes
= 4.12 PM

Solve: 3,125 = 5–10 + 3x
Answer: x = 3130/3 = 1043.333
Step-by-step explanation: Solve : -3x+3130 = 0
Subtract 3130 from both sides of the equation :
-3x = -3130
Multiply both sides of the equation by (-1) : 3x = 3130
Divide both sides of the equation by 3:
x = 3130/3 = 1043.333
Answer:
[tex]3125=5-10+3x\quad :\quad x=\frac{3130}{3}\quad \left(\mathrm{Decimal}:\quad x=1043.33333\dots \right)[/tex]

Write an equation in slope-intercept form for the line with slope 1/5 and y-intercept -8
Answer:
y= 1/5x + -8
Step-by-step explanation: slope-intercept form= y=mx+b
y= the number on the y-axis or the simple y
m=slope
x= the number on the x-axis or the simple x
b= y-intercept
The required slope-intercept form of the equation is given as y = 1/5x - 8.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope intercept of the equation is given as,
y = mx + c,
From the given, we have a slope of line m = 1/5 and y-intercept, c = -8.
Now,
y = mx + c
y = 1/5x - 8
Thus, the required slope-intercept form of the equation is given as y = 1/5x - 8.

what is the value of x in the equation 2(x-3)=4(x-4)?
Answer:
The value of x is 5
Step-by-step explanation:
Let us simplify each side at first
∵ 2(x - 3) = 4(x - 4)
∴ 2(x) - 2(3) = 4(x) - 4(4)
∴ 2x - 6 = 4x - 16
→ Subtract 4x from both sides
∴ 2x - 4x - 6 = 4x - 4x - 16
∴ -2x - 6 = -16
→ Add 6 to both sides
∴ -2x - 6 + 6 = -16 + 6
∴ -2x = -10
→ Divide both sides by -2
∴ [tex]\frac{-2x}{-2}=\frac{-10}{-2}[/tex]
∴ x = 5
∴ The value of x is 5

A farmer wants to increase the weight of her lambs and is considering supplementing their diets with niacin, which is advertised as an effective weight gain supplement. To add niacin to their diets, the farmer would need to purchase a supply, which is fairly expensive. But if it does actually increase the weights of her lambs, it will lead to higher sales for her farm over time. So she conducts an experiment where she compares the weight gains of a sample of lambs on regular feed to a sample that receives an additional niacin supplement. a. Write an appropriate null and alternative hypothesis for her experiment. (1pt) b. In the famer’s perspective, explain the consequence of a Type-I error. (1pt) c. In the famer’s perspective, explain the consequence of a Type-II error. (1pt) d. Suppose the farmer analyzed her experimental data and got a p-value of 0.15. What would be the appropriate conclusion? (2pt) e. List a potential confounding variable for this study
Answer:
H0: ρ= 0 against Ha : ρ≠0
Step-by-step explanation:
The null hypothesis would be the weight gains of a sample of lambs on regular feed is equal to the weight gains of the sample that receives an additional niacin supplement against the claim that the weight gains are not equal .
H0: ρ= 0 against Ha : ρ≠0
Type 1 Error would be when the H0 is true and there's no difference but H0is rejected or Ha is accepted that there is difference in the weight gains.
Type 2 Error would be when the Ha is true and there is difference but Ha is rejected or H0 is accepted that there's no difference in the weight gains.
The appropriate conclusion would be Ha is accepted and H0 is rejected fail to reject.
A confounding variable is the one which effects the results . It is the biased variable which should be identified and ignored.
For example in this experiment the independent variable would be the amount of the supplement the dependent would the weight gain but the gender of the sheep is the confounding variable. It is not directly related to amount of supplement .
1) gender of sheep
2) the breed of sheep
3) the number of sheep
4) the height of sheep

Ethan went shopping. He found some electronic games for $32.99 and I- pad for $200. He decided to purchase 3 electronic games and the l-pad. He had a discount card for 18% off, the sales tax is 8.5%. What is his total cost for these items? A. $270.57 B. $298.97 C. $352.78 D. $327.37
Answer: $298.97
Step-by-step explanation:
Cost of electronic games = $32.99
Cost of I- pad = $200
Since Ethan decided to purchase 3 electronic games and the l-pad, his total cost will be:
= (3 × $32.99) + $200
= $98.97 + $200
= $298.97
Can someone help me with angles please!!!!!! There are two problemsssss
Answer:
Question 1: 78 = angle 2.
Question 2: 7 = angle 2.
Step-by-step explanation:
Complementary deals with the angles adding up to 90 degrees.
So, do 90 - 12, which equals 78.
78 = angle 2.
90 - 83 = 7.
7 = angle 2.

Sarah made a scale drawing of a dinosaur.
she made the height of a dinosaur 2 1/2 inches.
the actual height of the dinosaur is 9 feet.
what scale did sarah use for her drawing?
1 inch=3.6 ft
1 inch=4.5 ft
1 inch=18 ft
1 inch=22.5 ft
Answer: The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)
Step-by-step explanation:
Here, we want to know the scale used for the drawing of the Dinosaur by sarah.
The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)
Mathematically, we know that 1 foot is 12 inches;
So the actual height of the Dinosaur is 9 * 12 = 108 inches
So practically, what she has done is to represent a height of 108 inches by 2.5 inches
So the scale factor used will be;
108/2.5 = 43.2
The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual
