9a. From 6 yards deep to 15 yards deep, the temperature is constant. So, the temperature at 10 yards deep is the same as it is 6 yards below the surface. The temperature has dropped 2° from the surface temperature for each of those 6 yards, so is (2°/yd)×(6 yd) = 12° less than the surface temperature.

At 10 yards deep, the temperature is 70° -12° = 58 °F

9b. From part A, we know that the temperature at 15 yards (45 feet) below the surface is 58 °F. For each of the 5 feet from 45 feet deep to 50 feet deep, the temperature is increasing 3°. At 50 ft deep, it will be (3°/ft)×(5 ft) = 15° higher than at 45 ft deep.

At 50 feet deep, the temperature is 58° +15° = 73 °F

9c. Based on the result from part B, we can write the expression for the temperature 20 yards (60 ft) deep as

... 73 °F + (3 °F/ft)×(10 ft) . . . . temperature 60 ft below the surface

_____

Evaluating this expression, we get the source temperature to be ...

... = 103 °F

Answer:

1. V = 157in³, so the volume of the sugar container is 157in³

2. h = 12in, so the height of the rice container is 12in

3. The rice container's height is 12in and the height of the sugar container is 8in, which means the rice container is taller by 4in. The rice container's volume is 235.5in and the sugar container's volume is 157in, so the rice container's volume is greater than the volume of the sugar container's volume by 78.5in.

4. V = 50.24in³, so the volume of the flour container is 50.24in³

5.  The rice container's volume is 235.5in, the sugar container's volume is 157in, and the flour container's volume is 50.24in. This means the container that contains the greatest volume is the rice container and the container that contains the smallest volume is the flour container.

Step-by-step explanation:

1. to find the volume of a cylinder, we use the formula:

V = πr²h

V = 3.14(2.5² × 8)

V = 3.14(6.25 × 8)

V = 3.14(50)

V = 157in³

2. To find the height of a cylinder when given the volume and radius, you use the formula:

h = V / πr²

h = 235.5/3.14(2.5²)

h = 235.5/3.14(6.25)

h = 235.5/19.625

h = 12in

h = height

3. The rice container's height is 12in and the height of the sugar container is 8in, which means the rice container is taller by 4in. The rice container's volume is 235.5in and the sugar container's volume is 157in, so the rice container's volume is greater than the volume of the sugar container's volume by 78.5in.

4.

V = bh

V = 12.56 × 4

V = 50.24in³

5. The rice container's volume is 235.5in, the sugar container's volume is 157in, and the flour container's volume is 50.24in. This means the container that contains the greatest volume is the rice container and the container that contains the smallest volume is the flour container.

Cole noticed that if he takes the opposite of his age and adds 40 he gets the number 28. how old is Cole?
AnnyKZ [126]
-x+40=28
-x=-12 (subtract 40 from both sides)

Divide by -1(in both sides)because you cant have a negative age.
COLE is 12
