The radius of a cylindrical water tank is 5.5 ft, and its height is 13 ft. What is the volume of the tank?
mezya [45]

Answer:

1235 ft³

Step-by-step explanation:

Volume of a Cylinder: 2πr²*h

π = 3.14

r = 5.5 ft

h = 13 ft

Volume = 2(3.14)(5.5)²*13 = 1235.43 ft³

Rounded to nearest whole number

Volume of the Cylindrical Water tank is 1235 ft³

A rock is projected directly upward from ground level with an initial velocity of 90 ft/sec. After how many seconds will it retu
Nastasia [14]
For this case we have the following equation of motion:
 h (t) = -16t ^ 2 + 90t
 Equaling the equation to zero we have:
 -16t ^ 2 + 90t = 0
 We look for the roots of the polynomial:
 (t) (- 16t + 90) = 0
 t1 = 0 (initial position)
 t2 = 90/16 = 5.625 s (time it reaches the ground again)
 Answer:
 
it will return to the ground in:
 
t = 5.625 s

Theorem: A line parallel to one side of a triangle divides the other two proportionately.
Kisachek [45]

Answer:

Segment BF = 16

Step-by-step explanation:

The given theorem states that a line parallel to one side of a triangle divides the other two sides proportionately

The given theorem is the Triangle Proportionality Theorem

According to the theorem, given that segment DE is parallel to segment BC, we have;

\dfrac{AD}{BD} = \dfrac{AE}{EC}

Therefore;

BD = \dfrac{AD}{\left(\dfrac{AE}{EC} \right) }  = AD \times \dfrac{EC}{AE}

Which gives;

BD = 6 \times \dfrac{18}{12}= 9

Similarly, given that EF is parallel to AB, we get;

\dfrac{AE}{EC} = \dfrac{BF}{FC}

Therefore;

BF = FC \times \dfrac{AE}{EC}

Which gives;

BF = 24 \times \dfrac{12}{18} = 16

Therefore, the statement that can be proved using the given theorem is segment BF = 16.

Please help!<br><br> Find the equation of this line.
rosijanka [135]

Answer:

y = 1/3x + 2

Step-by-step explanation:

Slope - Intercept Form = y = mx + b

y - intercept = b = 2 (point of intersection of the y-axis)

m = slope

Slope = Change in Y/Change In X

You can see that as the graph goes up by 1, it goes to the right 3, so slope = 1/3

Equation : y = mx + b

Equation : y = 1/3x + 2

Priya has picked 1 1/2 cups of raspberries which is enough for 3/4 of the cake how many cups does she need for the whole cake
Zina [86]

Answer:

So Priya need  2 cups of raspberries for the whole cake.

Step-by-step explanation:

Given data;

1\frac{1}{2}=\frac{3}{2} cups of raspberries which is enough for \frac{3}{4} of the cake.

For making \frac{3}{4} of the cake need \frac{3}{2} cups of raspberries.

For making 1 cake need \frac{\frac{3}{2}}{\frac{3}{4}} cups of raspberries.

For making 1 cake need \frac{3}{2} \times \frac{4}{3}=2 cups of raspberries.

∴ Priya need  2 cups of raspberries for the whole cake.
