Sarah has taken 4/5 portion of the available water bottles.

How is a ratio determined?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. A ratio is a comparison or condensed version of two quantities of the same type. We may determine how many times one quantity is equal to another using this relationship. The ratio can be defined as the number that can be used to represent one quantity as a percentage of another.

Given, Total number of water bottles bought = 4
Total number of people sharing the bottles = 5
Since each bottle is divided in equal portion, each portion of bottle = 1/5
Also, Sarah took one portion from each of the four bottles, thus
Sarah has portion of water = 4*(1/5) = 4/5
Sarah has taken 4/5 portion of the available water bottles.

Given:

The expression is,

Simplify the expression,

Answer: option G

Let

x -----> number of liters of 10% acid solution

y ----> number of liters of 70% acid solution

so

we have that

x+y=90 ------> x=90-y -----> equation 1

Remember that

10%=10/100=0.10

70%=70/100=0.70

20%=20/100=0.20

so

0.10x+0.70y=0.20(90) ------> equation 2

Solve the system of equations

substitute equation 1 in equation 2

0.10(90-y)+0.70y=0.20(90)

solve for y

9-0.10y+0.70y=18

0.60y=18-9

0.60y=9

y=15

Find out the value of x

x=90-y

x=90-15=75

therefore

the answer is

Using the uniform distribution, it is discovered that there is a 0.625 = 62.5% chance that a randomly picked passenger will have to wait longer than 2.25 minutes.

The boundaries of a uniform distribution are a and b.

The likelihood of discovering a value greater than x is:

P(X > x) = (b - x)/(b - a)

In this problem, the time is equally distributed between 0 and 6 minutes, so.

a=0

b=6

P(X > 2.25) is the probability of a time larger than 2.25 minutes, so:

P(X > x) = (6 - 2.25)/(6 - 0) = 0.625

A randomly picked passenger has a 0.625 = 62.5% chance of waiting longer than 2.25 minutes.

Using the angle and segment addition postulates, the measures are:

a. m<TSM = 95°

b. m<SIJ = 93°

c. SR = 12 units

d. PQ = 10 units

The angle addition postulate states that two smaller angles have a sum of measure that is equal to the larger angle they form.

Similarly, the segment addition postulate states that two smaller segments that make up a larger segment have a sum that equals the length of the larger segment.

a. m<TSM + m<MSR = m<TSR [angle addition postulate]

Substitute

x = -48/-16

x = 3

m<TSM = 32x - 1 = 32(3) - 1

m<TSM = 95°

b. m<HIS + m<SIJ = m<HIJ [angle addition postulate]

Step-by-step explanation:

Because you need to regroup the numbers, therefore leaving 4-4, which is just a 0, (don't include the 0 in a number).

The expression that represents the Volume , of the composite figure is (Four-thirds)π(10)³ + π(10)²(28) , the correct option is (a) .

In the question ,

it is given that

the composite figure has a cylinder and two hemisphere , one at top and other at bottom,

Formula for  Volume of Cylinder = πr²h ,where ,

r and h are radius and height of cylinder .

,

volume of Hemisphere = (2/3)πr³

where , r is the radius .

given the diameter of cylinder = 20

hence ,the radius of the cylinder = 10

and height of the cylinder = 28

So , the volume of cylinder = π(10)²(28)  ...(i)

since half sphere is stacked on the top and the bottom of the cylinder

the radius of sphere is also = 10

So, the volume of the one Hemisphere = (2/3)π(10)³    

the volume of the two Hemisphere = 2*(2/3)π(10)³

                                                          = (4/3)π(10)³     ....(ii)

The Volume of the composite figure = volume of cylinder + volume of the two Hemispheres

Substituting the values from (i) and (ii) , we get

Volume of the composite figure = π(10)²(28) + (4/3)π(10)³

Rewriting we get

= (4/3)π(10)³ + π(10)²(28)

in words , it is

= (Four-thirds)π(10)³ + π(10)²(28)

Therefore , the expression that represents the Volume , of the composite figure is (Four-thirds)π(10)³ + π(10)²(28) , the correct option is (a) .

The given question is incomplete , the complete question is

A cylinder is shown. A half-sphere is stacked on the top and the bottom of the cylinder. The diameter of the cylinder if 20 and the height of the cylinder is 28.

Which expression represents the volume, in cubic units, of the composite figure?

Investment X gives a greater amount of $50.40 over a period of two years

Investment X:

Principal amount invested = $6000

Time in years = 2 years

Rate of interest = 4.5%

Type of interest: Simple

Finding the interest using the formula for simple interest:

Simple interest = P*R*T/100

where P = principal invested

R = rate of interest

T = time in years

Substituting the values we get:

Simple interest = 6000*4.5*2/100

= $540

Investment Y:

Principal amount = $6000

Time in years = 2 years

Rate of interest = 4%

Finding the interest using the formula

Compound interest = P(1+r/100)^n - P

where P = principal amount invested

r = rate of interest

n = number of years

Substituting the values in the formula we get:

Compound interest = 6000(1+4/100)^2-6000

= (6000*1.0816)-6000

The external angle is the angle formed by any side of an object and a line that runs from another side.

An interior angle is the shape that results from joining the two rays at their terminal. An internal angle is the angle inside a shape. A polygon is a closed shape with sides and vertices.

If this angle is one, the total exterior angle is 360 degrees.

and if the angle is inside, enter 180 degrees.

I'm taking this given angles i.e, (7x+7)° and (2x+2)° as an exterior angle to solve for x.

Now, (7x+7)° + (2x+2)° = 360°

7x + 7 + 2x + 2 = 360°

9x + 9 = 360°

9(x + 1) = 360

x + 1 = 360 / 9

x + 1 = 40

x = 39

We get x = 39, now put these x value to find the angle

(7x+7)°               |           (2x+2)°

Using the sum of the areas of three intersecting squares, the Pythagorean Theorem shows how to get the side lengths of a right triangle. This theorem is an extremely useful technique that forms the basis for more complicated trigonometry concepts like the inverse of the Pythagorean theorem.

To determine the undiscovered side of a right-angled triangle, utilize the Pythagoras theorem. The hypotenuse (third side) of a right-angled triangle, for instance, can be determined using the formula c2 = a2 + b2, where 'c' stands for the hypotenuse and 'a' and 'b' are the two legs.

In two dimensions, the Pythagorean Theorem is helpful for navigation. You may calculate the shortest distance using it and two lengths. The two legs of the triangle will be north and west, and the diagonal will be the shortest line separating them. Air navigation can be done using the same ideas.
