The volume of the spherical beaker is 1436.76 cubic centimeters

In order to determine the volume the spherical beaker, you need the formula for the volume of a sphere.

The volume of sphere is given by the formula:

Volume of sphere = 4/3 πr³

where r is the radius of the sphere

Since the spherical beaker that measure 14 centimeters in diameter. The radius of the beaker will be:

radius = 14/2 = 7 cm

Volume of the spherical beaker =  4/3 × π × 7³

Volume of the spherical beaker = 1436.76 cubic centimeters

Jayden had to skim through an amount of 75 pages, in the given word problem.

A word problem is a few sentences that describe a "real-life" scenario in which a problem must be solved using a mathematical calculation.

Word problems are regarded as an important part of the primary curriculum because they require children to apply their knowledge of various concepts to'real-life' scenarios.

Let S = no. of skimmed pages

Let R = no. of read pages

Then S + R = 275

So R = 275 - S

Reading rate = 15 min/10 pages

Skimming rate = 10 min/15 pages

Total time to finish book = 350 min

So,

(R)(Reading rate) + (S)(Skimming rate) = 350 minutes

Substituting the values:

(275-S)(15/10) + (S)(10/15)=350

Multiplying equation through by 30 yields:

12375 - 45S + 20S = 10500

Combine terms

1875=25S

S = 75

Thus, Jayden had to skim through an amount of 75 pages.

Step-by-step explanation:

in an isoceles triangle (both legs have identical length) the height from the top corner to the baseline shots the baseline into 2 identical halves.

so,

6x + 6 = 9x - 15

6 = 3x - 15

==========================================================

Explanation:

The units for each are in feet.

The formula tying together all three variables is

P = 2(L+W)

which is the same as saying

P = 2L+2W

We can think of it having two copies of L and two copies of W, four sides total, added together to get the full perimeter.

I'll go with the first version. Plug in the given values and solve for L

P = 2(L+W)

2(L+W) = P

2(L+144) = 580

L+144 = 580/2

L+144 = 290

L = 290-144

L = 146 feet is the length

---------------

We can confirm this by saying

P = 2(L+W) = 2(146+144) = 2*290 = 580

Or we could say

P = 2L+2W = 2*146+2*144 = 292+288 = 580

or,

P = L+W+L+W = 146+144+146+144 = 580

Step-by-step explanation:

Therefore, F = c * M1 * M2 / d^2 when the force F of attraction between two bodies varies jointly as the weights of the two bodies and inversely as the square of the distance between them using the C constant.

Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.

Direction is characterized as the course that anything follows, the route that must be taken to go to a certain location, the direction in which something is beginning to take shape or the direction you are facing.

F = c * M1 * M2 / d^2

Where,

F is the force of attraction,

M1 and M2 are the weights of the two bodies,

d is the distance between the two bodies,

and c is the proportionality constant.

have an amazing day hope this helpsss<3

The equations are n + s = 76 and 2n + 1.50 s = 125.

let n = number of Nachos sold

let s = number of sodas sold

Two equations are presented to us, and we can use them together to solve one variable at a time.

Eq. 1: n + s = 76

Eq. 2: 2n + 1.50 s = 125

So, s = 76 - n

Put (76 - n) for s in the second equation

2n + 1.50 (76 - n) = 125

2n + 114 - 1.50 n = 125

2n - 1.50 n + 114 = 125

0.5n + 114 = 125

0.5n = 125 - 114

0.5n = 11

n = 22

s = 76 - 22

s = 54

22 nachos sold and 54 sodas sold.

Answer:

It would be 0.09

Step-by-step explanation:

First, note the original Probability for picking a blue marble in the first try:

0.3

Now, if this were to happen again, knowing that no marbles would be taken out, it would be another chance of 0.3 for Aron to pick up a blue marble on his second pick up.

Due to these being independent events, you can do:

0.3*0.3 = 0.09

To get your answer, 0.09.

1 - 63 / 90

27/90 is the probability of choosing 2 blues.

Answer:

a) will definitely be an odd number

Step-by-step explanation:

4^n is always even (when you multiply even and even number, the product is always even)

when you add one to even number, the sum is always odd
