Answer:

Answer:

Option B is the correct answer.

Step-by-step explanation:

Irina measured the weight of her dog as 13 pounds.

If value is 13 she rounded the values in between 12.5 to 13.49 to 13 pounds.

Maximum possible error = 13 - 12.5 = 0.5 pounds.

Maximum possible error = 0.5 pounds.

Option B is the correct answer.

Answers

Set the denominators equal to each other. 4/13 becomes 40/130 and 3/10 becomes 39/130. Therefore, 3/10 is slightly less. A number in between would be 39.5/130 which is equivalent to 79/260

A recipe for beef fajitas uses 5 pounds of beef to make 20 meals. How many pounds of beef are needed to make 80 meals?

Answers

Answer:

20 pounds

Step-by-step explanation:

80/20 =4

5x4=20

Final answer:

The amount of beef needed to make 80 meals, given a ratio of 5 pounds of beef for 20 meals, is 20 pounds.

Explanation:

To get an answer to this question, we first need to establish the ratio of beef needed for a single meal. The recipe suggests that 5 pounds of beef are used to create 20 meals. Thus, the ratio of beef to meals is 5:20. For simplicity, we can reduce this ratio by dividing both sides by 5, resulting in 1:4. This means for every meal, we need a quarter of a pound of beef.  The question then asks how many pounds of beef are needed for 80 meals. Since we know a quarter pound of beef is needed for each meal, we can simply multiply the number of meals by 0.25 to get the total pounds of beef required.  So, 80 meals x 0.25 pounds = 20 pounds of beef.

Polygon ABCDE rotates 45° clockwise about point F to produce polygon FGHIJ as shown. What is mBCD?

Answers

The order of letters is important. 
Since polygon ABCDE is rotated to produce polygon FGHIJ, then image of A is F, image of B is G, and so on.
And since rotation preserves the shape, then 
m∠BCD = m∠GHI = 127°
