BEST ANSWER GETS BRAINLIEST, PLZ ANSWER!!!!

Answer:

1) 3 marbles

2) The number of people born every hour is 9000 people

The number of people born every day is 216,000 people

The number of people born every year = 78,840,000 people

Step-by-step explanation:

1) The given information are;

The number of students =  3 or 6

Amount of marbles remaining after sharing = None

Least amount of marbles that can be shared equally among the students = Condition each student gets one marble = 1 × 3 = 3 marbles

The least amount of marbles that can be shared equally among the students = 3 marbles

2) The number of people born int eh world every minute = 150 people

The number of minute in one hour = 60 minutes

∴ The number of people born every hour = 150 × 60 = 9000 people

Given that the number of hours in one day = 24 hours

∴ The number of people born every day = 9000 × 24= 216,000 people

Given that the number of days in one year = 365 days

∴ The number of people born every year = 216,000 × 365= 78,840,000 people

Answer:

1 and 3.

Step-by-step explanation:

The given system of equations

[tex]2x-7y=-13[/tex]     ...(1)

[tex]-2x+11y=1[/tex]     ... (2)

Here, coefficients of x have same values with opposite signs.

The x-variable will be eliminated when adding the system of equations.

Add (1) and (2), we get

[tex]2x-7y-2x+11y=-13+1[/tex]

[tex]4y=-12[/tex]

Divide both sides by 4.

[tex]y=-3[/tex]

Put y=-3 in (1).

[tex]2x-7(-3)=-13[/tex]

[tex]2x+21=-13[/tex]

[tex]2x=-13-21[/tex]

[tex]2x=-34[/tex]

Divide both sides by 2.

[tex]x=-17[/tex]

So, the given system of equations have unique solution, i.e., (-17,-3).

Therefore, the correct options are 1 and 3.

Answer:

y = (-1/2)x - 3

Step-by-step explanation:

Please present the equation symbolically instead of in words:

m = -1/2, passing through (4, -5):

Using the slope-intercept formula y = mx + b, and using m = -1/2, x = 4 and y = -5, we get:

-5 = (-1/2)(4) + b, or -5 = -2 + b.  Then b = -3 and the desired equation is:

y = (-1/2)x - 3

y = -x/2 - 3 equation represents a line that has a slope of -1/2 and passes through point (4, –5)

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given that a line has slope -1/2 and passes through point (4, -5)

The standard equation of a line is y = mx + c where m is the slope of the line.

Solving for c,

-5 = -1/2*4 + c

c = -3

Hence, y = -x/2 - 3 equation represents a line that has a slope of -1/2 and passes through point (4, –5)

Answer:

1 Employee gets = Rs 13,020

Step-by-step explanation:

25% profit = Rs 26,04,000

Bonus is always 20% of the profit

So, Bonus:

=> 26,04,000/5

=> Rs 520,800

50% bonus  from the profit = 520,800/2

=> Rs 260,400

This was divided equally among 20 employees.

So, Each Employ gets:

=> 1 Employee = 260,400/20

=> 1 Employee gets = Rs 13,020

Answer:

y =  -[tex]\frac{1}{2}[/tex]x + 10

Step-by-step explanation:

To find the equation of a line that passes through the point (8,6) and perpendicular to the equation 2x - y = 4, we will follow the steps below:

first write the equation 2x - y = 4 in a standard form

we will find the slope of our equation using this equation

2x - y = 4

y = 2x -4

comparing the above with

y = mx  + c

m = 2

[tex]m_{1}[/tex][tex]m_{2}[/tex] = -1  ( slope of perpendicular equations)

2[tex]m_{2}[/tex] = -1

[tex]m_{2}[/tex]  = -1/2

our slope m = -1/2

We can now go ahead and form our equation

[tex]x_{1}[/tex] =8   [tex]y_{1}[/tex] =6

y-[tex]y_{1}[/tex] = m (x-[tex]x_{1}[/tex])

y-6 = -[tex]\frac{1}{2}[/tex](x-8)

y-6 =  -[tex]\frac{1}{2}[/tex]x + 4

y=  -[tex]\frac{1}{2}[/tex]x+4+6

y =  -[tex]\frac{1}{2}[/tex]x + 10

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

Work Shown:

a = 3 is the first term

r = 2 is the common ratio

Sn = a*(1-r^n)/(1-r) ... sum of the first n terms

S8 = 3*(1-2^8)/(1-2) ... sum of the first 8 terms

S8 = 3*(-255)/(-1)

S8 = 765

----------

We can generate the first 8 terms to get 3, 6, 12, 24, 48, 96, 192, 384. Each new term is found by multiplying the previous one by 2.

Then add them up to get 3+6+12+24+48+96+192+384 = 765. We get the same result.

Answer:

The answer is B.

Step-by-step explanation:

First you have to find the angle of ATB. Given that ∠TAB and ∠TBA have the same angle and the total angle in a triangle is 180°. So you have to subtract :

∠TAB + ∠TBA + ∠ATB = 180°

∠ATB + 62° + 62° = 180°

∠ATB + 124° = 180°

∠ATB = 180° - 124°

∠ATB = 56°

A tangent to a circle will always be 90°, so ∠TAO and ∠TBO are 90°. In a quadrilateral, total angles is 360°. So the angle of AOB is :

∠ATB + ∠TAO + ∠TBO + ∠AOB = 360°

56° + 90° + 90° + ∠AOB = 360°

236° + ∠AOB = 360°

∠AOB = 360° - 236°

∠AOB = 124°

Step-by-step explanation:

volume of pad : 8x8x1=64

64/5=12.8

so you would need 13 bags

Answer:

Step-by-step explanation:

Since the pad frame is a square frame measuring 8 feet long and 1 foot high, we would determine its volume by applying the formula for determining the area of a cuboid which is expressed as

Volume = length × width × height

Volume of pad frame = 8 × 8 × 1 = 64 cubic feet

Since each bag of cement will fill 5 cubic feet, then the number of bags that you will need to buy to ensure enough to fill the entire frame is

64/5 = 16.8

Approximately 17 bags

Answer:

6

Step-by-step explanation:

Split the shape into two shapes, one square and one triangle.

Find the area of the square and area of triangle.

area of square = 2 × 2 = 4

The height of the triangle is 4 - 2 = 2 units.

area of triangle = 2 × 2 × 1/2 = 2

Add the areas.

4 + 2 = 6

The area is 6 units².

Answer:

6

Step-by-step explanation:

It would be easier to divide this shape into a square and a triangle.

square = 2*2 = 4

triangle = [tex]\frac{2*2}{1/2}[/tex] = 2 (2 triangles make squares so 1 triangle is half)

And 4 + 2 = 6

Answer:

x = 29

Step-by-step explanation:

If the lines are parallel

< CBA = < DAB due to the fact that they are alternate interior angles

42 = DAB

We also know that

DAB + BAC + CAE = 180 since they form a straight line

Substituting the given values

42+ 109 + x = 180

Combine like terms

151 + x = 180

151+x-151 = 180-151

x = 29

Answer:

$10.10

Step-by-step explanation:

We are told that she bought 3 CDs of the same price. Her total was $34.20 with $3.90 tax. We want to find the price of a CD before tax.

Since we are finding the price before tax, we need to subtract the tax from the total.

total - tax

We know she paid $34.20 with the tax of $3.90

$34.20 - $3.90

Subtract

$30.30

The total before tax was $30.30

Now we must find the price of a CD. Each CD is the exact same price, and she bought 3. Therefore, we can divide the total before tax ($30.30) by 3.

$30.30 / 3

Divide

$10.10

Each CD costs $10.10 before tax.

Answer:

10.1 $

Step-by-step explanation:

The total price Lella paid was 34.20 $ wich includes the Cd's price and the taxes

The taxes value is 3.9 $

So we need to substract 3.9 $ from 34.20 $ to get the price of the Cds

34.20 -3.9 = 30.3

The total price of the cds is 30.3 $

There are 3 cds with the same price

To get the price of each Cd divife the total of cds by 3

30.3÷3 = 10.1

The price of 1 cd is 10.1$

Answer:

30 gallons of 6% milk, and 45 gallons of 1% milk.

Step-by-step explanation:

x=quarts of 6% butterfat

0.06x+0.01(75-x)=0.03*75

0.06x*100+0.01*100(75-x)=100*0.03*75

6x+75-x=3*75

6x+75-x=225

5x=225-75=150

5x=150

x=30

75-30=45

So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.

So, the mixture contains 60 quarts of 6% milk and 15 quarts of 1% milk

The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1

Let [tex]x[/tex] quats and [tex]y[/tex] quats of 6% and 1%  butterfat milk then,

[tex]x+y=75...(1)[/tex]

And

[tex]\frac{6x}{100} +\frac{y}{100} =375\\6x+y=375...(2)[/tex]

Now, solving equations (1) and (2) we get,

[tex]x=60\\y=15[/tex]
