a) Neither arithmetic nor geometric
b) Both arithmetic and geometric
c) Arithmetic
d) Geometric

Answers

Answer 1
Answer: a) Neither arithmetic nor geometric
Answer 2
Answer: a) Neither arithmetic nor Geometric

Explanation:
Since 99-89.9= 9.1, and 89.9 - 78.8 = 11.1, the sequence is not arithmetic.
Like wise 89.9/99=0.908 and  78.8/89.9 = 0.876 makes it not a geomtric sequence

The calorie count of a serving of food can be computed based on its composition of carbohydrate, fat, and protein. The calorie count for a serving of food can be computed using the formula C=4h+9f+4p, where his theof grams of carbohydrate contained in the serving, is the number of grams of fat contained in the serving, and is the number of grams of protein contained in the serving

A serving of a certain type of but contains 12 grams of fat, 6 grams of carbohydrate, and 5 grams of protein. How many calones are in this serving of ruts?

There are calories [___] in this serving of nuts

Answers

Answer:

152 calories

Step-by-step explanation:

The calories count, composition of carbohydrates, fat and protein are related by;

C = 4h + 9f + 4p

where C, h, f, and p have there given meaning.

Given that the serving of a type of nut contains; f = 12 grams, h = 6 grams and p = 5 grams, then;

C = 4(6) + 9(12) + 4(5)

  = 24 + 108 + 20

  = 152

C = 152 calories

Therefore, there are 152 calories in the serving of the certain type of nut.

Final answer:

The serving of nuts contains 152 calories.

Explanation:

To compute the calorie count for a serving of food, you can use the formula C = 4h + 9f + 4p, where C is the calorie count, h is the grams of carbohydrate, f is the grams of fat, and p is the grams of protein. In this case, the serving of nuts contains 12 grams of fat, 6 grams of carbohydrate, and 5 grams of protein. Plugging these values into the formula gives:

C = 4(6) + 9(12) + 4(5)

C = 24 + 108 + 20

C = 152

Therefore, there are 152 calories in this serving of nuts.

Jan bought a blazer for $39.90. The price of the blazer was $38. What sales-tax rate was she charged for this blazer percentage wiese

Answers

Answer:

5% sales-tax rate was she charged for this blazer

Step-by-step explanation:

As per the statement:

Jan bought a blazer for $39.90.

The price of the blazer was $38.

Sales tax price = 39.90 - 38 = $1.90

We have to find the sales-tax rate was she charged for this blazer percentage wise.

Using formula:

\text{Sales tax rate} = \frac{\text{Sale tax}}{\text{Price of the blazer}} * 100

Substitute the given value we have;

\text{Sales tax rate} = (1.90)/(38) * 100 = 5\%

Therefore, 5% sales-tax rate was she charged for this blazer percentage wise
The question asks for sales tax rate. Sales tax is 39.90-38=1.90 and that's taxed onto the original $38 so 1.9/38=0.05
5% tax on the blazer
