Answer:

Step-by-step explanation:

[tex]\tan(23^o)=\dfrac{25}x\\\\\ x\tan(23^o)=25\\\\x=\dfrac{25}{\tan(23^o)}\\\\x\approx 58.9[/tex]

Answer:

The answer is b) 18.75% decrease

Given:

The line contains the point (-5,-3) and has a slope of -2.

To find:

The graph of the line.

Solution:

The line contains the point (-5,-3) and has a slope of -2. So, the equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

where, m is slope.

[tex]y-(-3)=-2(x-(-5))[/tex]

[tex]y+3=-2(x+5)[/tex]

[tex]y+3=-2x-10[/tex]

Subtracting 3 from both sides, we get

[tex]y=-2x-10-3[/tex]

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

So, the equation of line is [tex]y=-2x-13[/tex].

Putting x=0, we get

[tex]y=-2(0)-13[/tex]

[tex]y=0-13[/tex]

[tex]y=-13[/tex]

It means, the line also passes through (0,-13).

Plot the points (0,-13) and (-5,-3) on a coordinate plane and connect them by a straight line.

Therefore, the graph of given line is shown below.

Answer:

40%

Step-by-step explanation:

6/15 = 0.4

0.4 * 100 = 40%

Answer:

40%

Step-by-step explanation:

Since there are 15 total kids and 6 of them are girls, we can write this question as the fraction 6/15.

6/15 is 0.4 and to get the percent you would multiply by 100%.

Therefore the answer is 40%

Find the slope first by using rise/run

[tex]m=\frac{6-(-1)}{4-(-2)}\\m=\frac{6+1}{4+2}\\m=\frac{7}{6}[/tex]

[tex]y=mx+b\\y=\frac{7}{6}x+b[/tex]

We need to find the y-intercept. Substituting one of given ordered pairs. I will use (-2,-1).

Substitute x = -2 and y = -1 in the equation.

[tex]-1=\frac{7}{6}(-2)+b\\-1=\frac{7}{-3}+b\\-1=-\frac{7}{3}+b\\-1+\frac{7}{3}=b\\b=\frac{4}{3}[/tex]

Thus the y-intercept is 4/3.

From y = mx+b, the equation is.

[tex]y=\frac{7}{6}x+\frac{4}{3}[/tex]

The interval that contains the median 25.5 is

(5 - 10)

The median is the value that's exactly in the middle of a dataset when it is ordered.

We have a histogram as given below.

We need to make a table of class intervals and their frequency:

class interval      frequency

0-5                       22

5-10                       5

10-15                       9

15-20                      9

20-25                      5

25-30                      1

We also need to find the cumulative frequency.

class interval      frequency    cumulative frequency

0-5                       22                 22

5-10                       5                   22 + 5 = 27

10-15                       9                  27 + 9 = 36

15-20                      9                   36 + 9 = 45

20-25                      5                   45 + 5 = 50

25-30                      1                      50 + 1 = 51

Now,

The number of questions = 50 ( even number)

Median:

= (50 + 1) / 2

= 51 / 2

= 25.5

We need to select the cumulative frequency where it is greater than the median.

So we have 27 which is at the interval (5 - 10).

Thus the interval that contains the median 25.5 is (5 - 10)

The unit rate of the penny dropped is faster than the rocket.

Unit rate is the ratio of two different units, with denominator as 1.

Therefore, rocket travelled 208 kilometres in 50 minutes at a constant rate and the penny dropped from a skyscraper could travel 153 kilometres in 1/2 hours at a constant rate.

The object that has the faster rate between the two can be found as follows:

50 minutes = 0.833333 hours

Rate of the rocket = 208 / 0.833333

Rate of the rocket = 249.60009984

Rate of the rocket = 249.60 km/hr

Rate of the penny dropped = 153 / 0.5

Rate of the penny dropped = 306 km/hr

Rate of the penny dropped = 306 km / hr

Therefore, the unit rate of the penny dropped is faster than the rocket.

Answer:

13. ∠x° = 99°

y° = 108

a ≈ 21.38

14. x° = 99°

Step-by-step explanation:

The given diagram is the diagram of a kite, therefore, we have;

One Pair of opposite angles are equal

Therefore, ∠x° = 99°

y° = 360 - 2 × 99 - 54 = 108

The base angles are;

(180 - 108)/2 = 36°

Similarly we have;

The side opposite ∠54° = 12 × 2 × cos(36°) ≈ 19.416

a/sin(63°) = 19.416/sin(54°)

a = sin(63°) × 19.416/sin(54°) ≈ 21.38

14. x° = 99°

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the total number of guest is x;

and, the Total Cost of Hosting a Private Party be y;

here it is given that :

A restaurant charges a $100 setup fee, plus $15 per guest, to host a private party then, this van be shown in linear equation as :

y = 15x + 100

Now, for 45 number of guests that is x = 45, then y will be :

y = 15x + 100

y = 15 x 45 + 100

y = 675 + 100

y = 775 $

Thus, the restaurant charge 775 $ in total for a private party with 45 guests.

The coordinates of the B is obtained as (-5, 3).

Coordinates are 2 numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane.

Now, as per the given question;

The coordinates of A is given as (1, 7).

The coordinates of mid point M is given as (-2, 5).

The coordinates are listed in pairs, with the x value at the top.

The shift in the x location is as follows:

1 - (-2) = 3

The change in y position is as follows:

7 - 5 = 2

Because the midpoint is half - way between B and A, the change will remain constant, so x is;

- 2 - 3 = -5

And for is;

5 - 2 = 3

Therefore, the values of the coordinates of B is found as (-5, 3).

If 1 mile equals 1.6 km, the distance these birds fly is 32000km.

Here we have,

Total miles = 20,000

Given, 1 mile = 1.6 kilometer

Thus, total km travel = 20000 x 1.6

Total km travel = 32000 km

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement.

Thus, some bird species travel 20,000 miles. These birds travel 32000 kilometers if a mile is equal to 1.6 kilometers.

We can say that any of the two given conditions are true -

        y = mx + c

        [m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

        [c] → is the y - intercept i.e. the point where the graph cuts the [y] axis

Other possible equations of line are -

We have a the point (1, 3) represent on the graph.

Assume that we represent the item produced is mentioned along the [x] - axis and revenue generated is along the [y] - axis. Since, the graph is not given, we can assume that any one of the given condition is true -
