In the summer, you charge people $10 for going to their house to mow lawns, then $6 for every hour you mow. If you make $34 one day, how many hours did you spend mowing?

Answer:

approx 4130

Step-by-step explanation:

x * .92 = 3800

3800/.92 = 4130.43478261

4130 approx. attendance before drop

Answer: 4,130

Step-by-step explanation:

Hi, to answer this we have to multiply the attendance before the drop (x) by the percentage that assisted after the drop ( 1-0.08) . That expression must be equal to the attendance after the drop (3800)

Mathematically speaking:

8% = 8/100 = 0.08 (decimal form)

x (1-0.08)= 3800

x (0.92) =3800

Solving for x

x = 3800/0.92

x= 4,130

Answer:

The area of shaded region is 226.4 meter squared.

Step-by-step explanation:

Radius of the circle = r =18.6 m

Angle subtended by chord[tex]\theta = 123^o[/tex]

Area of  sector = [tex]\frac{\theta }{360^o}\pi r^2[/tex]

In ΔOAB

∠A+∠B+∠O= 180°

2∠A+123°= 180°(∠A=∠B, isosceles triangle)

∠A=∠B=28.5°

AC=BC (Radius of the circle  bisects the chord at right angle.)...(1)

In ΔOAC

[tex]\sin 123^0=\frac{OC}{OA}[/tex]

OC = 8.87 m

[tex]\cos 123^0=\frac{AC}{OA}[/tex]

AC = 16.34 m

AB = AC+AB=16.34 m+16.34 m=32.68 m (from (1))

Area of the ΔOAB = [tex]\frac{1}{2}\times OC\times AB[/tex]

=[tex]\frac{1}{2}\times 8.87 m\times 32.68 m=144.93 m^2[/tex]

Area of segment = Area of sector - Area of triangle:

[tex]371.34 m^2-144.93 m^2=226.41 m^2\approx 226.4 m^2[/tex]

The area of shaded region is 226.4 meter squared.

Step-by-step explanation:

The possible outcomes include 1, 2, 3, etc., up through 25.  This in itself is insufficient to specify who will go first.  There must be some further criteria.

Suppose each player chooses and announces a number from this set by writing it down on a scrap of paper which is placed face-down on the table.  The person who chooses the smaller number goes first.  Or, the person who chooses the larger number goes first.

The possible outcomes are two which are success or failure.

A binomial distribution describes the possible number of times that a particular event will occur in a sequence of observations.

The conditions for the binomial distribution is,

A trial has only two possible outcomes namely success or failure.

There is fixed number п  of identical trials.

The trials of the experiment are independent of each other.

The probability of success remains same for each trial.

A residual is the space between each data point and the regression line.

Regression lines can graphically show the relationship between the independent (x) and dependent (y) variables in the graph.

Instead of being multiplied, divided, or given as a non-algebraic function, as has been the case up to this point in this section, the terms in a linear model are added. The use of linear modelling enables the analysis of experimental, financial, and biological data as well as the prediction of complex systems.

Linear regression is a statistical method for creating linear models. A dependent variable y (also known as the response) and one or more independent variables Xi are related in the model (called the predictors). A residual is the separation of each data point from the regression line.

The information is ,

Regression lines can be used to visually express the independent (x) and dependent (y) variables in a graph given data.

The regression line is sometimes sometimes referred to as the "line of best fit" since, when drawn across the points, it is the line that fits them the best. The disparity between the anticipated and actual scores is minimized by this line.

And , A residual is the separation of each data point from the regression line.

The gap between data points on a regression line is hence known as the residual.

Answer:

1/10

Step-by-step explanation:

To find the number of red guppies, multiply the fractions.

Gary has 2/5 of his fish collection as guppies. Of the guppies, 1.4 are red.

So 2/5 * 1/4 = 2/20 = 1/10.

Answer:

  11/12

Step-by-step explanation:

2 3/4 = 2·(4/4) + 3/4 = (8/4) +(3/4) = (8+3)/4 = 11/4

Then your problem becomes ...

  (11/4) / 3 = (11/4) · (1/3) = (11·1)/(4·3) = 11/12

___

The numerator and denominator have no common factors, so this is lowest terms.

Final answer:

The quotient of 2 ³/₄ divided by 3 is 11/12, and it is already in the lowest terms.

Explanation:

To calculate the quotient of 2  ³/₄ divided by 3, we first convert the mixed number to an improper fraction. So, 2  ³/₄ is the same as 11/4 (because 2 x 4 + 3 = 11). Next, we divide this improper fraction by 3, which is the same as multiplying by the reciprocal of 3, which is 1/3.

11/4 × 1/3 = 11/12. This gives us the final quotient, which is already in lowest terms, as 11 and 12 have no common factors besides 1.

Answer:

-2 is the slope

Step-by-step explanation:

To find the slope of the line, we need to solve for y

6x +3y = 12

Subtract 6x from each side

6x-6x +3y = -6x+12

3y = -6x+12

Divide each side by 3

3y/3 = -6x/3 +12/3

y = -2x+4

This is in slope intercept form

y = mx+b   where m is the slope and b is the y intercept

-2 is the slope and 4 is the y intercept

Point B in the graph represents the relationship to Sidhaanth's savings.

A point on the graph can be read as a point (x, y) where y is the perpendicular distance of the point from the x-axis and x is the perpendicular distance of the point from the y-axis.

We are asked to tell the point that represents Sidhaanth's savings among the points A and B.

We analyze each point like this:

Point A:

The perpendicular distance from the y-axis (x) = 1 unit.

The perpendicular distance from the x-axis (y) = 28 units.

∴ The point is (1, 28) which says that Sidhaanth's weekly savings are $28.00. This is not true, as his weekly saving, as seen from the table is $7.00.

So, point A doesn't represent the relationship to Sidhaanth's savings.

Point B:

The perpendicular distance from the y-axis (x) = 2 units.

The perpendicular distance from the x-axis (y) = 14 units.

∴ The point is (2, 14) which says that Sidhaanth saves $14.00 every 2 weeks. This is true, as we can see from the table that his savings in the 2nd week are $14.00.

So, point B represents the relationship to Sidhaanth's savings.

Answer:   The first transformation is a. a reflection across m.

The second transformation is b. a rotation about a.

∆ABC is c. congruent to​ ∆A'B"C".

Step-by-step explanation:

In the given picture, we can see that ΔABC is reflected across line m to create ΔA'B'C' such that all the corresponding points in both the triangles are equidistant from the line of reflection m.

∴ First transformation: Reflection across m.

After that, there is rotation of  ΔA'B'C' about point A' about some degrees such that, every corresponding points in both the triangles are equidistant from the point of rotation A'.

∴ Second transformation : Rotation about A'.

Since reflection and rotation are rigid transformations, therefore they produce only congruent figures.

Therefore, ∆ABC ≅ ∆A'B'C'

∆A'B'C' ≅  ∆A'B"C"

By law of transitivity of congruence,

∆ABC  ≅ ∆A'B"C"

16500 gallons

Step-by-step explanation:

Due to:

(1.35)*(10^4) = 13500

then, with the new pool with 3500 gallons, the total volumen will be:

Vt = 13500 + 3500

Vt = 16500 gallons

Best regards

The total volume of all pools at the water park after the new pool is installed is calculated by adding the volume of the new pool to the existing total pool volume. The calculation results in a total volume of 1.385 · 10^4 gallons.

To find the total volume of all the pools after the new pool is installed, we have to add the volume of the new pool to the combined volume of the existing pools. The combined volume of the three existing pools at the park is 1.35 · 10^4 gallons, and the volume of the new pool is 3,500 gallons.

So, the calculation would be: 1.35 · 10^4 gallons + 3,500 gallons.

When you calculate that, you get 1.385 · 10^4 gallons. Thus, the total volume of all the pools at the water park after the new pool is installed will be 1.385 · 10^4 gallons.
