If Mrs. Sharma spends 17/25 parts of her earnings on her children's education, then she is spending (17/25) x 100 = 68% of her earnings on her children's education.

If the number of children is the same, she spends 68%/number of children on her daughter education.

If she spends 68% of her earnings on her children's education, then she is saving 100 - 68 = 32% of her earnings.

So, she spends 68% on her daughter education and she saves 32% of her earning.

The value of the expression - 9(18 - 9 + 12) + 12(- 9 + 18 + 18) is 135.

If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.

There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.

Let, The rectangle be x, the triangle by y, and the star be z.

Therefore,The three linear equations are,

x + 3y + z = 57...(i)

12x + 5y = 234...(ii)

8x - 6x + 3x = 60...(iii)

5x = 60.

x = 12.

Putting the value of x in eqn(ii) we have,

12(12) + 5y = 234.

144 + 5y = 234.

5y = 90.

y = 18.

Now, Putting the value of x and y in eqn(i) we have,

12 + 3(18) + z = 57.

12 + 54 + z = 57.

z = - 9.

So, The value of the expression z(y + z + x) + x(z + y + y) is,

= - 9(18 - 9 + 12) + 12(- 9 + 18 + 18).

= - 9(21) + 12(27).

= - 189 + 324.

The value of angle X Is 85° ( nearest degree)

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

the law of sines is used to solve the triangle, when we know two angles and one side or two angles and one included side. It means that the law of sines can be used when we have ASA (Angle-Side-Angle) or AAS (Angle-Angle-Side) criteria.

therefore x/sin X = z/sinZ

89/sinX = 84/sin 70

89sin70 = 84sin X

= 89× 0.94 = 84sinX

=83.66 = 84sin X

sin X = 83.66/84

Answer:

The compound interest formula is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (expressed as a decimal), n is the number of times interest is compounded per year, and t is the number of years.

In this case, P = 2750, r = 0.035, n = 4 (because interest is compounded quarterly) and t = 7 (because we are trying to find the balance after 7 years).

So the formula becomes:

A = 2750(1 + 0.035/4)^(4*7)

By plugging the number into the formula we can find the final amount after 7 years

A = $3,974.23

So the amount of money in the account at the end of 7 years is $3,974.23, rounded to the nearest hundredth.

In order to find the values of k and m in a parallelogram, you would need to have additional information such as the coordinates of the points that make up the parallelogram and the formulas or equations that relate k and m to these points.

Here is one way to find the values of k and m in a parallelogram:

Label the four vertices of the parallelogram as A, B, C, and D with the opposite sides parallel to each other.

Find the slope of the line segment AB by using the formula (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Let the slope of AB be represented by k.

Find the slope of the line segment AD by using the same formula and let it be represented by m.

The values of k and m are now found.

Please note that, this method is only applicable if the Parallelogram is not degenerate i.e, it is not a rectangle or a line.

It is also important to keep in mind that different formulas or equations may be used depending on the specific context of the problem. It is also important to check that the slopes of opposite sides are equal.

In given fractions 8/9 is 1/36 large than 31/36

Finding the larger and smallest fraction in between two or more fractions is known as comparing fractions.

We need to change fractions with unlike denominators into fractions with similar denominators in order to compare them. For this, we will find the denominators' Least Common Multiple (LCM).    

If the denominators are the same then it is easy to compare the fractions.

Here we have

31/36 and 8/9

To find the largest fraction convert both denominators into the same  

Here LCM(36, 9) = 36  

Now multiply both numerator and denominators of fractions with a number to change the denominators  

=> [tex]\frac{31}{36} \times \frac{1}{1} = \frac{31}{36}[/tex]  

=> [tex]\frac{8}{9} \times \frac{4}{4} = \frac{32}{36}[/tex]  

From the above calculations given fractions are 31/36 and 32/36

Difference = [tex]\frac{32}{36} - \frac{31}{36} = \frac{1}{36}[/tex]  

Therefore,

Answer:

The minimum length and width of the tarp would be the diagonal length of the café's piece of ground. To find this length, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. In this case, the café's piece of ground forms a right triangle, with one side measuring 6.0 m and the other side measuring 5.0 m. So, to find the length of the hypotenuse, we can use the formula: c = √(a^2 + b^2) where c is the length of the hypotenuse and a and b are the lengths of the other two sides. Plugging in the numbers, we get: c = √(6.0^2 + 5.0^2) = √(36 + 25) = √(61) = 7.81 m

So, the minimum length and width of the tarp would be 7.81 m.

Answer:

Ryan

Step-by-step explanation:

Let's calculate the probabilities of John and Ryan hitting the target center

Let P(J) and P(R) be the respective probability representations

For John

John hits the center 1 time for every 3 tries(arrows)
Therefore

[tex]P(J) = \dfrac{1}{3}[/tex]

Out of 30 arrows (and therefore 30 attempts)  the expected number of times that John can hit the center is given by

[tex]30\cdot \dfrac{1}{3} = 10\\[/tex]

Since you need to hit the center more than 10 times, John is not expected to win the merit badge

For Ryan

Ryan Hits the center 2 times for every 5 arrows (attempts)

[tex]P(R) = \dfrac{2}{5}[/tex]

With 30 arrows the expected number of times that Ryan hits the target is:
[tex]30\cdot \dfrac{2}{5} = 18\\\\[/tex]

So Ryan is expected to win the Archery Merit Badge.

Important Note

Here you have to be careful of the words you use and interpret the results with some reality checks.

Probabilities after all are based on previous trials and represent only an estimate of guarantees of future events. That's why I have repeatedly used the word expected.

After all, John maybe able to hit the center a 11th time and thus he too will earn a merit badge.

m∠ABC = 180.

Step-by-step explanation:

In a triangle, the median to the side opposite the largest angle bisects that angle.

Since BM is a median, it bisects ∠C, the angle opposite side AB.

Let's call the angle opposite side AB angle x, so x/2 = 40.

Therefore, x = 80

Since a triangle has 180 degree, then if we add all the angles in the triangle we get:

m∠ABC = m∠BAC + m∠BCA + m∠CAB = x + (180-x) + (180-x) =180

So m∠ABC = 180

Explanation:

The TI-84 calculator is fairly powerful and can handle things like this, but it's not needed to be honest. Any calculator will do.

"csc" is shorthand for "cosecant". It's the reciprocal of sine.

csc = 1/sin

Recall that

sin = opposite/hypotenuse

which means

csc = 1/sin = hypotenuse/opposite

What we'll need are the hypotenuse and opposite sides. Plot the points (0,0) and (-20,21). Draw a segment between them. This forms the hypotenuse of the right triangle shown below. This triangle is in the quadrant Q2 in the upper left corner. The hypotenuse 29 is found using the pythagorean theorem a^2+b^2 = c^2.

Use a = 20 and b = 21 to find c = 29.

According to that diagram, we can then say:

csc = hypotenuse/opposite = 29/21

Answer: the estimated maintenance cost of cars when the age of cars is 12 years is 16.5 ( in 100 birr)

Step-by-step explanation:

To obtain the regression equation for costs related to age of cars, we can use the method of least squares. This method involves finding the line of best fit that minimizes the sum of the squared differences between the predicted values and the actual values.

The equation for a linear regression line is:

y = a + bx

where a is the y-intercept and b is the slope of the line.

To find the slope of the line (b), we can use the formula:

b = (n(∑xy) - (∑x)(∑y)) / (n(∑x^2) - (∑x)^2)

To find the y-intercept (a), we can use the formula:

a = (∑y - b(∑x)) / n

Given the data provided, we can calculate the following values:

∑x = 142

∑y = 150

∑xy = 2430

∑x^2 = 10304

n = 8

By substituting these values into the formulas for b and a, we can find the slope and y-intercept of the line:

b = (8(2430) - 142(150)) / (8(10304) - 142^2) = 0.5

a = (150 - 0.5(142)) / 8 = 13.5

Therefore, the regression equation for the costs related to age of cars is:

y = 13.5 + 0.5x

To estimate the maintenance cost of cars when the age of cars is 12 years, we can substitute x = 12 into the equation and solve for y:

y = 13.5 + 0.5(12) = 16.5

So the estimated maintenance cost of cars when the age of cars is 12 years is 16.5 ( in 100 birr)
