Answer: This question cannot be answered.

Explanation:

If you add three odd numbers, the sum must also be an odd number. To get an even number, you have to add an even number of odd numbers, e.g. 2 or 4. Adding 3 odd numbers to get 30 is therefore not possible. So the question cannot be answered.

What is the new volume of a right square pyramid with a volume 180in.3 if the lengths of the sides of the base remain fixed but

garik1379 [7]

The volume of a right square pyramid is $V= \frac{1}{3} A_{\text{ basis } }\cdot h$ , where $A_{\text{ basis } }$ is basis area.

If the lengths of the sides of the base remain fixed and height
is multiplied by a factor 10, than new height is $H=10h$ and the volume is

$V^{\ast}=A_{\text{ basis } }\cdot H=\frac{1}{3} A_{\text{ basis } }\cdot 10h=\frac{10}{3} A_{\text{ basis } }\cdot h$

If an object is dropped from a tower, then the velocity, V (in feet per second), of the object after t seconds can be obtained b

Amiraneli [1.4K]

Answer:

259.6 ft/sec

Step-by-step explanation:

it is a universal standard that acceleration due to gravity is 32ft/sec^2.

Now it can be verified by equation,

V(f) = V(i)+at (1st equation of motion derived by Newton's three laws of motion)

where,

V(f) is final velocity

V(i) is initial velocity

a is acceleration which is constant and have value 32ft/sec^2

t is time which is given as 7.8 seconds

In the given case, initial velocity that is V(i) will be 0ft/sec. Because, on dropping, object will start to move under the influence of gravity from zero speed.

So,

V(f) = 0 +(32) (7.8)

V(f) = 249.6 ft/sec

Now the condition is given that you have to add a constant 10 to the answer.

so, V(f) = 249.6 + 10

V(f) = 259.6 ft/sec

Calculate the perimeter of the figure below.

mote1985 [20]

Well, we know perimeter is just adding all the lengths together.

And we already know 2 of the lengths, so we know the rest. 11 1/2 is the same as the opposite side, and 6 1/3 is the same as the opposite side.

So the sides are 6 1/3, 6 1/3, 11 1/2, 11 1/2.

Add them up:

6 1/3 + 6 1/3 + 11 1/2 + 11 1/2.

Improper fractions:

19/3 + 19/3 + 23/2 + 23/2.

Common denominator, (6):

38/6 + 38/6 + 69/6 + 69/6 = 214/6.

Simplify:

214/6 = 35 2/3
