A farmer has 5 times as many cows as horses. The farmer only has cows and horses, and he has 168 animals. How many horses does he have

So here's gives that

total weight of 25 bags = 50 x 25

= 1250

total cost of 25 bags weighing 50 kg is = 15000

cost of 1 kg = 15000 ÷ 1250 = 12

now total weight of 15 bags weighing 30 kg = 450

cost per kg = 12

cost of 15 bags weighing 30 each = 450 x 12

Answer = 5400 rupees.

<JBC and <JBG(because these two angle are 45°)

by definition of acute angle any angle which is between 0°to 90° then it will acute angle

Answer:

x = 75°

Step-by-step explanation:

sum of interior angles of any polygon can be found using this formula:

(n-2)·180°, where 'n' is the number of sides

the shape in this problem has 6-sides, a hexagon

(6-2)·180 = 720°

x + 281 + 24 + 157 + 84 + 99 = 720

x  + 645 = 720

x = 720-645

x = 75°

You can use the fact that it needs longest time to do doctorate degree than any of the other degrees mentioned here.

The career to be chosen that will have the most vacation time is given by

Option D: Pharmacist, doctorate's degree.

Since it is given that there is positive correlation between number of years of education and the amount of vacation time, that means, as the number of years of education will increase, due to positive correlation, the amount of vacation time will increase too.

Two datasets having positive correlation move together(depending on how positive the correlation is (from (0,1] ), the more positive, the more together they move in same direction)

Negative correlation implies opposite movement.

Since doctorate's degree is of the longest length among other degree's given, thus,

You can use the fact that when coefficient of x variable are of equal magnitude but opposite sign, then adding them will make the coefficient 0, thus, making the x variable eliminated.

The numbers that can be multiplied by each equation so that when the two equations are added together, the x term is eliminated is given by

Option A: –10 times the first equation and 3 times the second equation

This method is actually called method of elimination to solve a system of linear equations.

We make one specific variable's coefficients of equal magnitude so that we can subtract or add the equations and eliminate that variable to make it easy to get the value of the other variable which will then help in getting the value of the first variable (if working in dual variable system).

If we have equations:

[tex]a_1x + b_1y = c_1\\a_2x + b_2y = c_2[/tex]

then, if we want to eliminate variable x, then we have to multiply equation 1 with

[tex]- \dfrac{a_2}{a_1}[/tex]

which will make coefficient of x in first equation as

[tex]a_1 \times - \dfrac{a_2}{a_1} = -a_1[/tex]

Then adding both equation will eliminate the variable x.

We could've skipped that -ve sign and at then end, instead of adding, we could've subtracted the equations.

5 has 5 as magnitude, and sign isn't present which means its of positive (+) sign.

-5 has 5 as magnitude and sign is negative(-).

For this case, we're multiplying both the equations but the core concept or aim is same, ie, making the coefficients of equal magnitude but with opposite sign.

The given system of equations is

[tex]\dfrac{1}{5}x + \dfrac{3}{4}y = 9\\\\\dfrac{2}{3}x - \dfrac{5}{6}y = 8[/tex]

Let two numbers be p,and q who multiply equation first and second respectively to make coefficient of x of equal magnitude but opposite sign.

We have

[tex]\text{Coefficient of x in first equation}= a_1 = \dfrac{1}{5}\\\\\text{Coefficient of x in second equation} = a_2 = \dfrac{2}{3}[/tex]

Multiplying with p and q will give us

[tex]p\times a_1 = \dfrac{p}{5}\\\\q \times a_2 = \dfrac{2q}{3}[/tex]

We need both resultant coefficient to add up to 0, or

[tex]p/5 + 2q/3 = 0\\p = -10q/3\\q = -3p/10[/tex]

Now in options, we see first equation is either getting multiplied with -10, 10, or -3,3

If we put q = 3, we get p =  -10q/3=  -10

If we put q = -3, we get p = 10

If we put q = 5, we get p = -50/3

Thus only first choice is matching the correct pairs.

Thus,

The numbers that can be multiplied by each equation so that when the two equations are added together, the x term is eliminated is given by

Option A: –10 times the first equation and 3 times the second equation

I know i am 2 weeks late but the answer is B, Have a good day :))

The distance between Earth and the moon is 3.8 x 10^3 Kilometers. The time taken to travel this distance was 2.1 x 10^3 Minutes.

The formula to calculate speed is Speed = distance/time.

So, the speed of Luna I was 3.6 x 10^3 / 2.1 x 10^3 Kilometers/Mintues.

Answer:

Part a =

The distance between Earth and the moon is 3.8 x 10^5  kilometers. The time taken to travel this distance was 2.16 x 10^3 minutes.

The formula to calculate speed is speed = distance/time.

So, the speed of Luna I was 3.8 x 10^5/2.16 x 10^3  kilometers/meters.

Part b =

The expression from part A is 3.8 x 10^5/2.16 x 10^3 kilometers/meters. Break the expression into the product of two fractions, one fraction for the first factors and the other for the powers of 10.

3.8/2.16 x 10^5/10^3

Part c =

3.8/2.16 x 10^5/10^3

Using division, the value of the first fraction is 3.8/2.16 = 1.759 = 1.76.

Using the properties of exponents, the value of the second fraction is 10^5/10^3 = 10^5 x 10^-3 = 10^ 5 - 3 = 10^2.

3.8/2.16 x 10^5.10^3 = 1.76 x 10^2

Part d =

The value 1.76 x 10^2 is written in scientific notation. So, the average speed of Luna I was 1.76 x 10^2 kilometers/minute.

the max height of ball

y-coordinate represents the maximum height of the baseball.

A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

Given that the height of a baseball hit from a bat is modeled by a quadratic function of time, h(t).

The vertex of a quadratic function is a point on the graph that is the highest or lowest point of the graph.

The coordinate of the vertex is represented as (x, y).

The x-coordinate of the vertex represents the time at which the baseball hits the maximum height, and

the y-coordinate represents the maximum height of the baseball.

Hence,  y-coordinate represents the maximum height of the baseball.

The amount each of Andrew, Brendan, and Clair gets is given by

representation as fractions.

Response:

Given:

The amount to be divided = R4 625

Every R4 Andrew gets, Brendan gets R3

Every R4 Brendan gets Clair gets R3

The amount each person gets from the R4625 to divided is found as

follows;

Let x represent the amount Andrew gets, we have;

Amount Brendan gets = [tex]\frac{3}{4}[/tex]·x

Amount Clair gets = [tex]\frac{3}{4}[/tex]·[tex]\frac{3}{4}[/tex]·x = [tex]\mathbf{\frac{9}{16}}[/tex]·x
