Answer:

surface area= 2261.95

volume=4423.36

Step-by-step explanation:

cone sa= 628.32

628.32*2= 1256.64

cylinder sa= 1005.31

1005.31+1256.64=2261.95

cylinder v=2412.74

cone v=1005.31

1005.31*2=2010.62

2010.62+2412.74=4423.36

please mark me brainliest :)

Suppose 15 quarts of a solution that is 35% antifreeze is mixed with 5 quarts of a solution that is 72% antifreeze. 1.how many q
Finger [1]

Answer:

1. 8.85 quarts

2. 44.25%

Step-by-step explanation:

In 15 quarts of a solution with percentage of antifreeze = 35%

Amount of antifreeze = 35% × 15

                                    = 0.35 × 15

                                    = 5.25 quarts

that solution is mixed with 5 quarts of a solution with percentage of antifreeze = 72%

Amount of antifreeze = 72% × 5

                                    = 0.72 × 5

                                    = 3.6 quarts

Total amount of mixture = 15 quarts + 5 quarts = 20 quarts

1. Now we will calculate the total amount of antifreeze in the resulting mixture.

= 5.25 + 3.6 = 8.85 quarts

2. The percentage of the resulting mixture is antifreeze

= \frac{8.85}{20}\times 100

= 44.25%

1. total amount of antifreeze is 8.85 quarts

2. the percentage of antifreeze is 44.25%

zimovet [89]

Answer is given below

Step-by-step explanation:

given data

average length of all 1015 fishes = 98.06 mm

randomly selects 50 fishes average length = 101.04 mm

solution

  • When we get here, we mean to measure, so here we measure a fish in a square lake.
  • And the variable means that a fish varies from fish to fish, so the length of the fish in the squares
  • parameter mean that all individuals in the population so the parameter is average length of all 1015 fish in square lake
  • statics is selct of individual in sample so statistic is average length of random sected so fish in square lake
