We know that one angle is 104 and angles greater than 90 and less than 180 are obtuse

We know that 2 sides are equal indicated by the lines on the sides.  That means the triangle is isosceles

Answer:

Yes, she will be able to retrieve the item

Step-by-step explanation:

The information with regards to the research historian interest in finding a sunken treasure are;

The depth from which the equipment can recover items = 5,000 m

The speed of sound through water, v = 1,530 m/s

The time it takes the echo from the item to return to the sonar detector, t = 6.2 s

Let d, represent the depth at which the item is located

Given that an echo travels from the sonar detector to the item and back to the sonar detector, the distance traveled by the sound wave which is received as an echo by the sonar detector = 2 × d

Velocity, v = Distance/time

∴ Distance = Velocity × Time

The distance traveled by the echo = 2 × d = v × t

2 × d = v × t

∴ 2 × d = 1,530 m/s × 6.2 s

d = (1,530 m/s × 6.2 s)/2 = 4,743 m

The depth at which the item is located, d = 4,743 m is less than the maximum depth the equipment can recover items, therefore, she will be able to retrieve the item.

Answer:

Splash Island.

Step-by-step explanation:

Magic Park = 32 - 7 = 25 you would have 25 dollars to spend on rides which would only get you 5 rides.

Splash Island = 32 - 14 = 18 this gives you 18 dollars to spend on rides, which would get you 6 rides.

Therefore you can go on more rides at Splash Island.

Answer:

90degrees

Step-by-step explanation:

To get the measure of angle C, we will use the cosine rule as shown;

AB² = AC²+ BC² - 2(AC)(BC)cos C

85² = 13²+ 84² - 2(13)(84)cos C

7225 = 169 + 7056 - 2184cosC

7225 - 7225 = -2184cosC

0 = -2184cosC

cosC = -0/2184

cosC = 0

C = arccos0

C = 90degrees

Hence the measure of angle C is 90degrees

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

A x - 36 <42 is wrong because its saying how many can be added

B x +36 < 42 this one is most likely correct because its displays x as how many can be added

C x - 36 > 42 this is wrong because the bus has less than 42 seats

D x + 36 >57 like i said cant be over 42

The inequality representing the possible number of passengers that can be added to the bus is Option(B) x + 36 < 42.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. Inequality is used most often to compare two numbers on the number line by their size. There is always a definite equation to represent it.

Let x be the number of passengers that can be added to the bus.

It is given that the bus has less than 42 seats and 36 seats are already occupied.

The sum of the remaining seats which are to be filled by the passenger and the 36 seats which are filled, must be less than the total seats that is 42.

Therefore the inequality equation becomes,

x + 36 < 42.

Thus, the inequality representing the possible number of passengers that can be added to the bus is Option(B) x + 36 < 42.

Answer: y-intercept = (0, -18)

Step-by-step explanation:

This is a quadratic equation question, where the quadratic equation is in the standard form of [y = ax² + bx + c]

The function of [a] in the equation is to determine the maximum/minimum of the parabola. If [a] is positive, then the parabola opens upward, which is a minimum. If [a] is negative, then the parabola opens downward, which is a maximum.

There aren't any particular functions of [b], but it operates with [a] to find the axis of symmetry.

The function of [c] is the y-intercept. The easiest way to prove this is to let x be zero, then we are left with the value [c]

Solve:

Given: y=-x²+8x-18

a = -1

b = 8

c = -18

Therefore, the y-intercept is (0, -18)

Answer:

Yes, the function is symmetric about y-axis.

Step-by-step explanation:

To check whether the function is symmetric with respect to y-axis, replace each x as -x and simplify.

If h(x) = h(-x) then it is symmetric about y-axis.

Let's find h(-x) now.

h(-x)= [tex](-x)^4} -5(-x)^{2} +3[/tex]

Let's simplify it

h(-x)=[tex]x^{4}-5x^{2} +3[/tex]

Here, h(x) = h(-x). The function is symmetric about y-axis.

The range of loads for this washing machine is from 2 to 6 kilograms to ensure energy efficiency and avoid overloading.

Given that,

The washing machine should wash at least 2 kilograms of clothes to use energy efficiently.

To avoid overloading the machine, the maximum weight that should be washed is 6 kilograms.

To find the range of loads for this washing machine,

Determine the minimum and maximum weight that can be washed.

The minimum weight that can be washed is 2 kilograms, as mentioned. And the maximum weight is 6 kilograms, as overloading the machine should be avoided.

Therefore,

The range of loads for this washing machine is from 2 kilograms to 6 kilograms.

This means that any load within this range can be efficiently washed without overloading the machine.

Answer:

Step-by-step explanation:

1) ML // JK , MK is transversal,

∠LMK = ∠MKJ   {Alternate interior angles are congruent}

∠LMK = 30°

In ΔMKO,

30 + 115 + ∠ JLM = 180  {Angle sum property of triangle}

        145 +∠ JLM  = 180

∠ JLM  = 180 - 145

∠ JLM = 35°

2) AB // CD , AC is transversal

∠DCA = ∠BAC     {Alternate interior angles are congruent}

∠DCA = 23

∠BCD = ∠DCA + ∠BCA

          = 23 + 37

          = 60

3) EF // HG ; FH  is transversal

∠FHG = ∠HFE   {Alternate interior angles are congruent}

 ∠FHG = 77

4) ZY // WX ;  WY is transversal

∠ZYW = ∠XWY         {Alternate interior angles are congruent}

            = 65

ZY // WX ;  WY is transversal

∠ZWY = ∠WYX   {Alternate interior angles are congruent}

           = 36

In  ΔWZY

36 +  65 + ∠z = 180

        101 +∠Z = 180

∠Z = 180 - 101

∠Z = 79

Answer:

Perpendicular

Step-by-step explanation:

Perpendicular lines intersect and create 4 90 degree angles

Line AB and CD intersect and create 4 90 degree angles therefore line AB and CD are perpendicular

==========================================================

Explanation:

It helps to add point labels. Let's place point A at the very top point of the triangle. Then point B will be at the 90 degree angle. Point C is the far left point. Lastly, point D is on segment BC such that DC = 3.

Since BC = 8 and CA = 17, we can use the pythagorean theorem to get...

(AB)^2 + (BC)^2 = (AC)^2

(AB)^2 + (8)^2 = (17)^2

(AB)^2 + 64 = 289

(AB)^2 = 289-64

(AB)^2 = 225

AB = sqrt(225)

AB = 15

Now focus on triangle ABD and apply the pythagorean theorem again to find side AD

(AB)^2 + (BD)^2 = (AD)^2

AD = sqrt(  (AB)^2 + (BD)^2  )

AD = sqrt(  (AB)^2 + (BC-CD)^2  )

AD = sqrt( (15)^2 + (8-3)^2 )

AD = sqrt(250)

AD = sqrt(25*10)

AD = sqrt(25)*sqrt(10)

AD = 5*sqrt(10) .... answer is choice B

Answer:

[tex]\sqrt{30}-3[/tex]

Step-by-step explanation:

Write the given expression in a numerical format:

[tex]\frac{7\sqrt{3}}{\sqrt{10}+\sqrt{3}}[/tex]

A logical first step to take in this problem is to convert the denominator to a rational value. Currently, the denominator is an irrational value, meaning that it is a never-ending value. One wants it to be a rational value. This can be done by multiplying the denominator by its conjugate. The conjugate of this number is simply the denominator with the second addend times negative one. Remember to multiply both the numerator and denominator by this value, as a number over itself is the same as multiply by (1) Use this idea here:

[tex]\frac{7\sqrt{3}}{\sqrt{10}+\sqrt{3}}[/tex]

[tex]=\frac{7\sqrt{3}}{\sqrt{10}+\sqrt{3}}*\frac{\sqrt{10}-\sqrt{3}}{\sqrt{10}-\sqrt{3}}[/tex]

Simplify,

[tex]=\frac{7\sqrt{3}}{\sqrt{10}+\sqrt{3}}*\frac{\sqrt{10}-\sqrt{3}}{\sqrt{10}-\sqrt{3}}[/tex]

[tex]=\frac{7\sqrt{3}(\sqrt{10}-\sqrt{3})}{(\sqrt{10}+\sqrt{3})(\sqrt{10}-\sqrt{3})}[/tex]

[tex]=\frac{7\sqrt{30}-7\sqrt{3*3}}{\sqrt{10*10}-\sqrt{3*3}+\sqrt{10*3}-\sqrt{10*3}}[/tex]

Note that any value times itself under the radical is equal to the number, meaning ([tex]\sqrt{a*a}=a[/tex]). Apply this to the problem,

[tex]=\frac{7\sqrt{30}-7\sqrt{3*3}}{\sqrt{10*10}-\sqrt{3*3}+\sqrt{10*3}-\sqrt{10*3}}[/tex]

[tex]=\frac{7\sqrt{30}-7*3}{10-3}[/tex]

Answer:

18

Step-by-step explanation:

The interior and exterior angle of a polygon is supplementary

let interior be I

let exterior be E

I + E = 180

Since the interior angle is 8 times that of an exterior angle,

8E + E = 180          [replacing I with 8E]  

9E = 180                

E = 20                      

The exterior angle is 20 degrees

I + E = 180          

I + 20 = 180      

I = 160              

The interior angle is 160 degrees.

The equation to find the interior angle of a polygon with 'n' number of sides is:

I = ( (n − 2) × 180 ) ⁄ n

We know the interior angle, so plug it in and solve for n:

160 = ( (n − 2) × 180 ) ⁄ n      

160n = (n − 2) × 180            

160n = 180n − 360                  

-20n = -360                            

n = 18
