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

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.

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
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
Step-by-step explanation:
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

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

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1. Apple juice costs 56p for a 1-litre carton. Mango juice costs £1.20 for a 1-litre carton. A pack of 80 plastic cups costs £1. Nita sells her fruit drink at a school concert in 250ml cups for 60p each. She gives all the profit she makes to the school fund. Nita makes 80 cups of the fruit drink and sells them all. How much money does she give to the school fund?
Answer:
£32.60
Step-by-step explanation:
Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1. Apple juice costs 56p for a 1-litre carton. Mango juice costs £1.20 for a 1-litre carton.
A pack of 80 plastic cups costs £1. Nita sells her fruit drink at a school concert in 250ml cups for 60p each.
We are told that Nita sells all her 80 cups
100 pence = £1
60p =
= 60/100
= £0.6
Hence, the selling price =
£0.6× 80
= £ 48
Profit = Selling Price - Cost Price
We have to find the Cost Price
A pack of 80 plastic cups costs £1.
Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1.
3 + 1 = 4
1 liter = 1000ml
For Apple Juice
3/4 × 1000ml = 750ml
For Mango Juice
= 1/4 × 1000ml = 250ml
This means she uses a mixture of 750 ml of Apple juice and 250 ml of Mango juice
Apple juice costs 56p for a 1-litre carton.
£0.56 = 1 liter = 1000ml
1000ml = £0.56
750 ml =
= 750 × 0.56/1000
= £0.42
Mango juice costs £1.20 for a 1-litre carton.
1000ml = £1.20
250 ml = x
x = 250 × 1.20/1000
= £0.3
Hence, the total cost for 1000ml of mixed juice = £0.3 + £0.42
= £ 0.72
We are told the content of each cup = 250 ml
For 80 cups she would need
80 × 250 ml
= 20000ml of the mixed juice
If 1000 ml = £0.72
20000ml = x
x = 20000 × £ 0.72/1000
x = £14.4
1 pack of 80 cups cost £1
Hence: £14.4 + £1
Cost Price = £15.4
Profit = Selling Price - Cost Price
Profit = £48 - $15.4
Profit = £32.60
Therefore, the money she gives to the school fund is £32.60
Can someone help me with angles please!!!!!! There are two problemsssss

Step-by-step explanation:
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

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
182 people rode the roller coaster.
307 people rode the roller coaster.
A total of 921 people had ridden the roller coaster.
So, Number of people rode the roller coaster
= 921 - 182 - 307
= 432
