What is the length of segment DF?

Answer:

Step-by-step explanation:

Multiply the numbers:

-5x*15x + 12x - 4x.

Which should get you: -75xx + 12x - 4x

Then combine exponents : -75xx + 12x - 4 = -75x^2 + 12x - 4x

Combine like terms: -75x^2 + 8x

Then find common factor with is -1

Lastly, rewrite in factored form : -1(75x^2 + 8x) = -1(75x - 8)x

The length of the segment EF for the given trapezoids is 6 cm.

Quadrilaterals called trapezoids have two parallel and two non-parallel sides. It also goes by the name Trapezium. A trapezoid is a closed, four-sided shape.

An opposing set of sides are parallel. The four angles of a trapezium add up to 360 degrees, and their diagonals cut each other in half. It has four odd-numbered sides. Thus, the opposing sides of an isosceles trapezium are congruent, as well as the diagonals.

Trapezoids ABCD and EFGH are similar,

Hence, corresponding sides ratio are equal:

Thus, AB/EF = DC/HG

24/x = 30/7.5

30x = 180

x = 180/30

x= 6

Hence, the length of the segment EF is 6 cm.

If the relationship between his hours of work (x) and the amount of money in his bank account (y) is represented by equation "y = 10x + 50" , then the money did he have in his bank account before he started working is $50 .

The equation y = 10x + 50 shows the relationship between Hamal's hours of work (x) and the amount of money in his bank account (y).

When x = 0, the equation becomes y = 10(0) + 50, which simplifies to y = 50. So when Hamal has not worked any hours, he has $50 in his bank account.

In other words, the y-intercept of the equation is 50, which represent the amount of money Hamal had in his bank account before he started working.

Answer: (-5x+3) - (-7x7) = -5x + 3 - (-7x7) = -5x + 3 + 7x7 = 2x7

The expression (-5x+3) - (-7x7) is the result of subtracting two algebraic expressions. When subtracting algebraic expressions, we need to distribute the negative sign to each term before combining like terms.

The first step is to distribute the negative sign to each term in the second expression, (-7x7). This gives us:

(-5x+3) - (-7x7) = -5x+3 + 7x7

Now we can combine the like terms, x7, to get the simplified expression:

-5x+3 + 7x7 = 2x7

So the final answer is 2x7.

The price drops by 35%, so it keeps the remaining 65% (since 100-35 = 65)

65% of $60 = 0.65*60 = 39 dollars

The linear equation for the coordinate points given is obtained as y = -3/2x + 19.5.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The coordinate points for the lines are (11,3) and (7,9).

The slope-intercept form of an equation/function is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

[9 - 3]/[7 - 11]

(6)/(-4)

3/-2

So, the slope point is obtained as m = 3/-2.

The equation becomes - y = -3/2x + b

To find the value of b substitute the values of x and y in the equation -

3 = -3/2(11) + b

3 = -33/2 + b

b = 3 + 33/2

b = (6 + 33)/2

b = 39/2

b = 19.5

So, the value for b is 19.5.

Now, the equation becomes -

y = -3/2x + 19.5

The graph for the equation is plotted.

Therefore, the equation is obtained as y = -3/2x + 19.5.

The amounts are obtained using a system of equations, for which the variables are given as follows:

Noah spent $150 to buy movie tickets for 15 students and 3 adults, hence:

3a + 15s = 150

a + 5s = 50

a = 50 - 5s

Adult tickets cost $4 more than student tickets, hence:

a = 4 + s.

The solution for s is then obtained as follows:

The lengths of the line segments in the requested units are:

AC = 50 mm

CF = 30 mm

EG = 0.15 m

A line segment is a part of a line that is defined by two distinct endpoints and all the points on the line between them.

The length of a line segment is the distance between the two endpoints. The two endpoints are also known as the "extremities" of the line segment

The length of the line segments in the requested units is as follow.

From the figure AC = 5 cm and CF = 3cm

Since 1cm = 10mm. Thus:

AC = 50 mm

CF = 30 mm

EG = AB and  AB = 15 cm

EG = 15 cm

Since 100 cm = 1m

Answer:

The correlation coefficient of 0.29 indicates that the correlation is a weak positive correlation. Thus option (D) is the correct answer.

What is correlation?

"Correlation is a statistical tool that studies the relationship between two variables. Data sets have a positive correlation when they increase together, and a negative correlation when one set increases as the other decreases".

For the given situation,

Correlation coefficient = 0.29

Positive correlation: the two variables change in the same direction.

Negative correlation: the two variables change in opposite directions.

No correlation: there is no association or relevant relationship between the two variables.

The correlation coefficient lies between 0 to 0.3 indicating that the correlation is a weak positive correlation.

Hence we can conclude that option (D) weak positive correlation is the correct answer.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The sum of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse. ​

1) Area of design = area of rectangle + 2(area of triangle)

Area of design = (60×30) + 60×45

Area of design = 1800 + 2700

Area of design = 4500 ft²

2) Area covered by grass =  2(area of triangle)

Area covered by grass =   = 60×45

Area covered by grass = 2700 ft²

3) installment of grass is $0.55 per ft².
