A person race walking a distance of 20 kilometers in 100 minutes is more faster with a speed of 0.2 kilometer per minutes.

Mathematically, the speed of a physical object or body can be calculated by using this formula;

Speed = distance/time

Next, we would convert the unit of distance covered by the bird in miles to kilometers as follows:

1 mile = 1.60934 kilometer.

10,000 miles = X kilometer.

Cross-multiplying, we have:

X kilometer = 10,000 miles × 1.60934 kilometer.

X kilometer = 16,093.4 kilometer.

Also, we would convert the unit of time in days to minutes as follows:

1 day = 1,440 minutes

75 days = X minutes

Cross-multiplying, we have:

X minutes = 75 days × 1,440

X minutes = 108,000 minutes.

Now, we can calculate the speed of this bird as follows:

Speed = 16,093.4/108,000

Speed = 0.1490 kilometer per minutes.

For the speed of the person, we have:

Speed = 20/100

Speed = 0.2 kilometer per minutes.

By using trignometry we got the side p as 6.67

Use the cosine rule of trignometry to find side p

p² = r² + q² - 2rqcosP

To find the angle of p we will simply subtract angle R and angle Q from 180.

180 - 47.28 - 40 = 92.72

p² = 8² + 7² + 2(8)(7)cos(92.72)

p² = 107.685

p = √107.685

p = 10.38

Let's suppose that the shortest distance of R from PQ is .

look at the diagram I gave

since the line I made makes a right angled triangle, we can use SOH CAH TOA

for the angle 40,  is opposite and 10.38 is hypotenuse

which means we will have to use SOH

sin40 = O/H

sin40 =x /10.38

0.6428 = x/10.38

0.6428 × 10.38 = x

x = 6.67

Hence, by using trignometry we got the side p as 6.67

The equation of the line with coordinates (-7,3), (8,3) is y-3=0 as the slope of line is 0 because x-ordinate is same in both the points.

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

Answer:

(- 12, 10 )

Step-by-step explanation:

2x + 4y = 16 → (1)

- 2x - 3y = - 6 → (2)

add (1) and (2) term by term to eliminate x

0 + y = 10

y = 10

substitute y = 10 into (1) and solve for x

2x + 4(10) = 16

2x + 40 = 16 ( subtract 40 from both sides )

2x = - 24 ( divide both sides by 2 )

x = - 12

The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.

To keep your bill at $50 or lower for the month, you need to set up an inequality using the cost function C(x):

C(x) = 40 + 0.20(x - 60)

Since you want to keep the cost at or below $50, the inequality is:

C(x) ≤ 50

Now, substitute the expression for C(x) into the inequality:

40 + 0.20(x - 60) ≤ 50

40 + 0.20x - 12 ≤ 50

0.20x + 28 ≤ 50

Now, isolate the term with "x" on one side by subtracting 28 from both sides:

0.20x ≤ 50 - 28

0.20x ≤ 22

Finally, divide both sides by 0.20 to solve for "x":

x ≤ 22 / 0.20

x ≤ 110

The maximum number of calling minutes you can use to keep your bill at $50 or lower is 110 minutes. If you use 110 minutes or less, your bill will not exceed $50.

The equation of line in the given graph with coordinate points (2,-2) and (-3,-6) is 4x-5y=18.

A straight line's general equation is y = mx + c, where m is the gradient and y = c is the value at which the line intersects the y-axis. This value c is known as the y-axis intercept. Linear equations are classified into three types: point-slope, standard, and slope-intercept. The equation of a two-dimensional line is ax+by=c; it is fair to predict that the equation of a three-dimensional line is ax+by+cz=d; reasonable, but incorrect—it turns out that this is the equation of a plane.

The possible solutions are 8 hours and 9 hours.

The number of hours for lifeguarding is 8 hours.

The number of hours for clearing tables is 9 hours.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Two summer jobs:

Lifeguarding.

x = number of hours

= $19 per hour

Cleaning tables.

y = number of hours

=$14 per hour

Total hours in a week = 17 hours

Minimum earning = $280

The inequality represents the above situation.

x + y ≥ 17

19x + 14y ≥ 280

Solving for x and y.

x + y = 17 _____(1)

x = 17 - y

19x + 14y = 280 ______(2)

Putting (1) in (2) we get,

19(17 - y) + 14y = 280

323 - 19y + 14y = 280

323 - 5y = 280

323 - 280 = 5y

43 = 5y

y = 43/5

y = 8.6

y = 9

Now,

x = 17 - y

x = 17 - 8.6

x = 8.4

x = 8

Thus,

The possible solutions are 8 hours and 9 hours.

The number of hours for lifeguarding is 8 hours.
