An ice cream shop's goal is to sell a mean of 45 ice cream cones per day. In one week, it sold the following numbers of ice cream cones each day.54, 45, 33, 39, 48, 40, 41

How many more ice cream cones would it have had to sell during the week to meet its goal?

A. 15
B. 25
C. 35
D. 5

Answers

Answer 1
Answer: To achieve its goal, it needed to sell at least a total of 45*7 = 315 cones each week. but it only sold 54+45+33+39+48+40+41= 300 cones.
therefore it needs 315 - 300 = 15 more cones to meet its goal.

Answer:

a. 16

Step-by-step explanation:

area of a triangle=1/2(bh). In this case, b=10 and h=3 1/5

multiply 10 and 3 1/5 to get 32

multiply 32 by 1/2 to get 16.

WRITE 0,000003 56 IN SCIENTIFIC NOTATION ​

Answers

Answer:

3.56X10^-6

Step-by-step explanation:

In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:

1. The numerical coefficient.

2. Number of times we move the decimal point. It will be the exponent with the base of 10.

3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.

Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.

The relationship between the number of cups of flour, f , and the number of cups of milk, m , used in a cake recipe can be modeled by the equation f = 1 2 m . How many cups of flour should be used for 1 cup of milk?

Answers

Answer:

f = (1/2)(m), for m = 1

f = (1/2)(1)

Step-by-step explanation:

Final answer:

To use 1 cup of milk, 1/2 cup of flour should be used.

Explanation:

The relationship between the number of cups of flour, f, and the number of cups of milk, m, used in a cake recipe can be modeled by the equation f = 1/2m. To find out how many cups of flour should be used for 1 cup of milk, we can substitute 1 for m in the equation. Plugging in the value of m, we get:



f = 1/2 * 1 = 1/2



So, 1/2 cup of flour should be used for 1 cup of milk.
