The situation above described that Jeff added two - thirds of 128 to the
flour. The numerical value of (2/3)(128) is 85.33 grams. The recipe
says to add only 32 grams of vanilla flour.
Hence, Jeff went over the
prescribed amount.
To determine the excess amount, subtract 32 from 85.33 which has a numerical value of 53.33 grams.
Note: to round to the nearest ten, look to the first place digit. if it is 5 or greater, round up, if 4 and lower, round down
<em>124 rounded to the nearest ten = 120</em>
<em>38 rounded to the nearest ten = 40</em>
<em>71 rounded to the nearest ten = 70</em>
<em>207 rounded to the nearest ten = 210
120 + 40 + 70 + 210 = 120 + 110 + 210 = 230 + 210 = 440
440, or C </em>is your answer
hope this helps
Answer:
is B
Step-by-step explanation:
Answer:
6000 square millimeters
Step-by-step explanation:
Side length of the slanting side can be calculated using the Pythagorean theorem,
L = sqrt(30^2+40^2) = 50
sufrace area of a triangular prism
= surface area of the end sections + the surface area of the three side faces
= 2*(30*40/2) + 40*(30+40+50)
= 1200 + 4800
= 6000 mm^2
