Camillo estimates the weight of his dog. The veterinarian says that the dog weighs 84 pounds. The percent error in Camillo's estimates is less than 10%.Decide whether each of the following weight estimates could have been Camillo's estimate.
a. 80 pounds yes or no
b. 78 pounds yes or no
c. 94 pounds yes or no
d. 77 pounds yes or no
e. 92 pounds yes or no
f. 75 pounds yes or no
Answers
Answer:
A.Yes B.Yes C.No D.Yes E.No F.No
Step-by-step explanation:
10% of 84 is 8.4 and 84-8.4=76.6 and anything between 76.6-84 could have been the estimate.
Final answer:
Camillo's weight estimate could have been 80 pounds, 78 pounds, 77 pounds, or 92 pounds.
Explanation:
The percent error measures the discrepancy between an estimated value and an actual value. It is calculated using the formula: Percent Error = (|Measured Value - Actual Value| / Actual Value) * 100%. Since the given problem states that Camillo's estimate has a percent error less than 10%, we can calculate the percent error for each weight estimate and determine if it is less than 10%.
- a. 80 pounds: Percent Error = (|80 - 84| / 84) * 100% = 4.76%, which is less than 10%. So, yes, this could have been Camillo's estimate.
- b. 78 pounds: Percent Error = (|78 - 84| / 84) * 100% = 7.14%, which is less than 10%. So, yes, this could have been Camillo's estimate.
- c. 94 pounds: Percent Error = (|94 - 84| / 84) * 100% = 11.9%, which is not less than 10%. So, no, this could not have been Camillo's estimate.
- d. 77 pounds: Percent Error = (|77 - 84| / 84) * 100% = 8.33%, which is less than 10%. So, yes, this could have been Camillo's estimate.
- e. 92 pounds: Percent Error = (|92 - 84| / 84) * 100% = 9.52%, which is less than 10%. So, yes, this could have been Camillo's estimate.
- f. 75 pounds: Percent Error = (|75 - 84| / 84) * 100% = 10.71%, which is not less than 10%. So, no, this could not have been Camillo's estimate.

(Choice B) B Eli's hot cocoa
Step-by-step explanation:
Arjun makes hot cocoa, he adds 20 mL of chocolate syrup for every 3 ounces of hot water.
Ratio of chocolate syrup to hot water = 20 : 3
= 20 / 3
= 6.67
Eli adds 45 mL of chocolate syrup for every 6 ounces of hot water.
Ratio of chocolate syrup to hot water = 45 : 6
= 45 /6
= 7.5
The ratio of Eli's chocolatey hot cocoa is more than Arjun's chocolatey hot cocoa.
The correct answer is B Eli's hot cocoa
Answer: The answer is the B Eli's hot cocoa .

Plug in 3 for length, 9 for height, and 13 for width. ( or however you’d like for width length height but only one number can be represented by h, l, and w.)
Then we add all the numbers
2(3)(13)+ 2(3)(9) + 2(9)(13) = SA (surface area)
78 + 54 + 234 = 366 in^2 or 366 sq. inches
Final answer:
The given dimensions are of a rectangular prism, and the surface area can be calculated using the formula 2lw + 2lh + 2wh, which gives 366 square inches for a prism with dimensions 13 inches, 9 inches, and 3 inches.
Explanation:
The numbers given, 3 inches, 9 inches, and 13 inches, are usually the dimensions of a rectangular prism, which is a type of box shape. The Surface Area of a rectangular prism is given by the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Based on the numbers given, we can see that :
- The length l=13 inches
- The width w=9 inches
- The height h=3 inches.
So, substitute these values into the formula:
Surface area = 2lw + 2lh + 2wh = 2(13x9) + 2(13x3) + 2(9x3) = 234 + 78 + 54 = 366 square inches.
This means the surface area of the box is 366 square inches. The surface area of a shape is a measure of the total area that the surface of the shape covers.
