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.

The number of hours for clearing tables is 9 hours.

1.  Elijah is the smallest sibling among his brother who is 4 years older than her and Bryan is the eldest sibling who is twice as James, what is his age of James if the sum of their ages is 80 years?

2. If the equation in step B had been 2(x + 4) = 80,  the changed statement would be Bryan is 80 years old.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Here we are converting a numerical expression into a statement.

Given,

Step A

Let x = Elijah’s age.

x + 4 = James’s age

2(x +4) = Bryan’s age.

Step B

x + x + 4 + 2(x +4) = 80.

Step C 4x + 12 = 80

X = 17

Step D James is 21.

The greatest width possible if the length of the rectangular lot is 25 ft longer than twice the width and if the perimeter of the lot cannot exceed 350 ft is 50 ft.

We are given,

The length of the rectangular lot is 25 ft longer than twice the width.

The perimeter of the lot cannot exceed 350 ft.

Let the width of the rectangular lot be x.

So, the length of the rectangular lot =  2x + 25

We know that the perimeter of the rectangle is given by:

P = 2(L + W)

Substitute the given values in the above formula;

350 = 2(2x +25 + x)

350 / 2 = 3x + 25

175 - 25 = 3x

x = 150 / 3

x = 50 ft

So, the width of the rectangular lot = 50 ft

And, the length of the rectangular lot = 2 * 50 + 25 = 125

Thus, the greatest width possible if the length of the rectangular lot is 25 ft longer than twice the width and if the perimeter of the lot cannot exceed 350 ft is 50 ft.

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. A plane, unlike a line, does not have a clear "direction."

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.

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

The average speed of the truck is 50 m/s .

We know that the average speed of any vehicle is calculated by total distance divide by total time.

Now the truck travels at 50 m/s for 30 seconds.

Distance covered in 30 seconds = 50 × 30 = 1500 meters

Time taken = 30 seconds

average speed = 1500 / 30 = 50 m/s

The average speed now accounts for the majority of the distance travelled. Average speed is essentially a method for calculating distance and the rate of transit time.

Knowing the average speed is crucial because it is clear that the pace will vary throughout the voyage. The average speed of a vehicle or an object can be determined using a variety of methods.

That is the most popular and simple way for figuring your average speed. It functions best when the object's speed remains constant throughout the journey, never rising or falling.

Step-by-step explanation:

If (x + 3) is a factor of f(x) = x³ + kx + 3 , then the value of k is -8 .

In the question ,

it is given that ,

the function is f(x) = x³ + kx + 3 ,

and also given that (x+3) is a factor of f(x) , that means

x + 3 = 0

x = -3

x = -3 should satisfy the function ,

So , substituting x = -3 in the function f(x) = x³ + kx + 3,

we get

f(-3) = (-3)³ + k(-3) + 3 = 0

-27 -3k + 3 = 0

-3k - 24 = 0

-3k = 24

k = 24/(-3)

k = -8

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

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Considering the coefficient a, we have;

If a < 0, the vertex is a maximum point.

If a > 0, the vertex is a minimum point.

In this question, the function is modeled as follows, considering x as the price divided by $2.

P(x) = -15x² + 60x + 30.

The coefficients are a = -15 < 0, b = 60, c = 30, therefore the x-value of the vertex is given by:

V = -60/2(-15)

V = -60/-30
