Answer:

KL=33

Step-by-step explanation:

Since all three sides have the ( symbol it means that all the angles in the triangle are the same. In a triangle with all the angles congruent the side lengths are also congruent.

As such you can make an equation where one side length equals the other.

10x+3=3x+24

10x-3x=24-3

7x=21

x=3

then just substitute 3 for x

3(3)+24=KL

9+24=KL

33=KL

Also it took me forever to understand this concept, trust me it can easily get confusing. I hope this helps!

Answer:

Step-by-step explanation:

All three angles are marked in a way to indicate that they are equal. That means the side opposite them are also equal to another side of the same triangle.

In other words KL = JK

So the equation parts are also equal

10x + 3 = 3x + 24                 Subtract 3x from both sides

10x - 3x + 3 = 3x - 3x + 24   Combine

7x + 3 = 24                           Subtract 3 from both sides

7x +3-3 = 24 -3

7x = 21                                  Divide by 7

7x/7 = 21 / 7

x = 3

KL = 3x + 24

KL = 3*3 + 24

KL = 9 + 24

KL = 33

Answer: 120, 60, 180

Step-by-step explanation:

1) Area of a rectangle's formula is:

l × w

So, looking at the diagram, we get:

6 × 20 = 120 cm²

2) Area of a trapezoid's formula is:

\frac{a+b}{2} × h (where both a and b are the different base lengths)

So, looking at the diagram, we get:

\frac{10+20}{2} × 4 = 60 cm²

3) Add both to find the area of the entire figure.

120 + 60 = 180 cm²

Linda and Imani are each traveling in a car to the beach. Linda’s travel is modeled by a table. Imanis travel it modeled by grap
tino4ka555 [31]

Answer:

Imani traveled faster because her distance surpassed Linda's distance after the fourth hour.

Step-by-step explanation:

1. Understand the slope:

      Ok, so the slope basically tells us how fast Imani and Linda traveled, so if we solve for the slope we know how fast Imani and Linda traveled.

2. Find Linda's slope:

      - Take any two points: (0,10) and (1, 65).

      Slope = (<u>y1 - y2)/(x1 - x2)</u>

<u> </u>                 = (65-10)/(1-0)

                   = 55

    Since the slope is 55, we know her speed is 55 miles per hour.

2. Find Imani's slope:

      - Take any two points: (0,0) and (1, 60).

      Slope = (<u>y1 - y2)/(x1 - x2)</u>

<u> </u>                 = (60-0)/(1-0)

                   = 60

    Since the slope is 60, we know her speed is 60 miles per hour.  

3. Compare: Since 60>55, we know Imani traveled faster. If we look at options, we can see there's only one answer which shows that Imani traveled faster, so that must be the answer.

The system of inequalities is:

y ≤ -0.05*x^2 + 6x

y >  1.5x + 45

(30, 90) is not a solution of that system, while (60, 160) is a solution.

<h3>How to get the system of inequalities?</h3>

We know that the revenue y is given by:

y ≤ -0.05x^2 + 6x

And we know that the costs are 1.5x + 45, and the revenue must be larger than that, so we also have the inequality:

y >  1.5x + 45

So the system is:

y ≤ -0.05*x^2 + 6x

y >  1.5x + 45

Now, the point (30, 90) means that we need to replace x by 30 and y by 90, replacing that in the second inequality, we will get:

90 > 1.5*30 + 45 = 90

90 > 90

This is false, so the point is not a solution of this inequality, meaning that the point is not a solution of the system.

For the second point we do the same: x= 60, y = 160, replacing that in the second inequality we get:

160 > 1.5*60 + 45 = 135

160 > 135

This is true, now we need to check with the other inequality.

160 ≤  -0.05*60^2 + 6*60 = 180

This is also true.

So the point (60, 160) is a solution to the system.

The water temperature at the beach
tester [92]

Answer: 69˚

All of the graphs for the surf breaks presented on Surf-Forecast.com are on the same scale to enable comparison between locations around the world.

Ocean Beach water temperatures peak in the range 13 to 17°C (55 to 63°F) on around the 8th of September and are at their lowest on about the 7th of April, in the range 10 to 14°C (50 to 57°F). The highest water temperatures at Ocean Beach in early to mid September are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days. At its lowest in the first part of April, low water temperatures at Ocean Beach are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

Actual sea surface water temperatures close to shore at Ocean Beach can vary by several degrees compared with these open water averages. This is especially true after heavy rain, close to river mouths or after long periods of strong offshore winds. Offshore winds cause colder deep water to replace surface water that has been warmed by the sun. Air temperature, wind-chill and sunshine should also be considered before deciding on the kind of wetsuit needed to stay warm when surfing at Ocean Beach.

Hope this. helps!~
