Answer:
Step 1: 798/ 8= 99.75
Step 2: 99.75 * 41 = 4089.75
The first significant figure is the first non-zero digit in a number. Therefore the first significant figure in 4089.75 is 4.
If the number following the value that you are rounding to (in this case, the first significant figure ie 4) is greater than or equal to 5, round up the value, ie add 1 to the number. Otherwise round down to the nearest whole number.
Since the number following the significant digit, 4, is zero we therefore round down the number.
Resulting in:
4000.
Therefore, your answer is 4000
Answer:
She will need 3.5 pounds of cheese to make the 28 casseroles
Step-by-step explanation:
In this question, we are tasked with calculating the amount of cheese in pounds needed to make 28 casseroles.
In the revised recipe, she intends using 1/2 of what is supposed to be used in the original recipe. Mathematically, since each original casseroles is meant to take 4 ounces of cheese, the revised recipe taking half will have 1/2 × 4 = 2 ounces of cheese per casserole
Now for 28 casseroles based on the revised recipe, the total amount of cheese to be used mathematically is equal to 28 × 2 = 56 ounces of casserole
The questions asks that our answer be in pounds
Mathematically, 1 ounce = 0.0625 pounds
Hence, 56 ounces of casseroles will be 56 × 0.0625 = 3.5 pounds of cheese
Answer:
Distance: 
units
Step-by-step explanation:
The distance formula is 
where:
is the distance between points 
and 
- are the coordinates of the first point
- are the coordinates of the second point
We are given that:
To determine the value of our distance, , we plug in our given information into the formula and solve for
Therefore, the distance between 
and 
is units.
