What is the length of the altitude of the equilateral triangle below?

Answer:

[tex]x^{2}y-z^{2}[/tex]

Step-by-step explanation:

Apply [tex](a+b)(a-b) = a^{2} -b^{2}[/tex] where [tex]x\sqrt{y}[/tex] is [tex]a[/tex] and [tex]z[/tex] is [tex]b[/tex].

[tex](x\sqrt{y} )^{2}-z^{2}[/tex]

[tex](x\sqrt{y} )^{2}=x^{2}y[/tex]

[tex]x^{2}y-z^{2}[/tex]

Hope this helps! :]

I really want to thank you for the answer and explanation.

Answer:

No

Step-by-step explanation:

Answer: NO

Step-by-step explanation: Put in (-7) in place of x, and (7) in place of y in the equation If the equation does not equal -2, it is not a solution. If it does equal -2, it is a solution.

(-7,7)

6x+9y=-2

Plug in -7 for x and 7 for y.

6(-7)+9(7)=-2?

Solve the equation.

-42+63= -21

So, (-7,7) is not a solution to this equation.

Answer:

<B=39.80

Step-by-step explanation:

tan(b)=5/6

b=[tex]tan^{-1}[/tex](5/6)

b=39.80557109

b=39.80 to the nearest hundredth.

Answer:

[tex] \angle B= 39.81\degree[/tex]

Step-by-step explanation:

[tex] \because \tan \angle B = \frac {AC}{BC} \\\\

\therefore \tan \angle B = \frac {5}{6} \\\\

\therefore \tan \angle B = 0.833333333\\

\therefore\angle B= \tan^{-1}(0.833333333)\\

\therefore\angle B= 39.805569965\degree \\

Answer:

$44,000

Step-by-step explanation:

The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:

x*0.09= 4,050

Now, you can isolate x to find her salary this year:

x=4,050/0.09= 45,000

Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:

45,000-1,000= 44,000

According to this, the answer is that her salary in the previous year was $44,000.

Answer:

MODE is the number which appears most often in a set of numbers. Here no number is repeated. So, there is no MODE

As the other user stated, the mode is the value that appears the most

Simply look for which colour has the most number of flowers

Thus, the mode would be "yellow"

Answer:

-$32

Step-by-step explanation:

Given that

Overdraft fee = $30

Preston Balance = $50

Total expenditure = $52

As per the given question the solution of new balance is provided below:-

To reach the new balance of Presont's first we need to find out the overdraft balance which is as follows:-

Overdraft balance = Balance - Total expenditure

= $50 - $52

= -$2

Since there is a balance of $50 but Pretson purchased for $52 value that results -$2 overdraft balance. In order to determine the new balance we simply added the overdraft fee and overdraft balance which is shown in negative sign.

Now according to the question the New balance of Presont's = Overdraft balance - overdraft fee

= -$2 - $30

= -$32

Answer:

h = 6 cm

Step-by-step explanation:

The volume (V) of a pyramid is calculated as

V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of base and h the height )

Here A = 3 × 2 = 6 cm² and V = 12 , thus

[tex]\frac{1}{3}[/tex] × 6 × h = 12, that is

2h = 12 ( divide both sides by 2 )

h = 6 cm

Answer:

area of the figure ≈61.23 cm² to the nearest hundredth

Step-by-step explanation:

To find the area of the figure, we will follow the steps below;

Looking at the figure, we will see that the figure comprises of both semi-circle and a parallelogram

area of figure = area of semicircle + area of parallelogram

first, we will find the area of the semi-circle

area of a semi-circle = πr² /2

from the diagram given, diameter = 7cm

but diameter = 2r, this implies that radius r = d/2, hence radius r = 7/2 = 3.5 cm

π = 3.14

Lets insert the values into the formula

area of a semi-circle = πr² /2

                                    =3.14×3.5² /2

                                    =3.14×12.25 /2

                                     =19.2325 cm²

Area of a parallelogram = b×h

where b = base and h = height

from the figure given, base b = 7cm   and height h = 6 cm

Lets insert the values into the formula

Area of a parallelogram = b×h

                                       = 7×6

                                       =42 cm²

area of the figure = area of semicircle + area of parallelogram

                                =19.2325 cm²   +   42 cm²

                                =61.2325 cm²

                                ≈61.23 cm² to the nearest hundredth

area of the figure ≈61.23 cm² to the nearest hundredth

Answer:

9u+5

Step-by-step explanation:

Answer:

5(9+u)

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

To solve these problems, you first set up an equation representing the information given.

6x = x² - 27

This turns into a quadratic equation which you need to factor out.

0 = x² - 6x - 27

You want to choose two numbers that multiply to -27, and add up to -6

0 = (x - 9)(x + 3)

If you're unfamiliar with factoring, you take the opposite sign of the number in the parentheses because it's a shortcut when setting it equal to 0.

x = 9, -3

Since it asks for the positive solution only, the answer is x = 9.

I hope this helps!

Step-by-step explanation:

Answer:

99°

Step-by-step explanation:

We know that angles on a straight line add up to 180° so we can set up an equation to find the value of x.

In an equation it's important to do the operation you want to on both sides because if you do an operation on one side only you will end up changing the whole equation and that will make the value of x wrong so its an important rule to remember.

8x - 13 + 7x - 17 = 180

→ Simplify

15x - 30 = 180

→ Add 30 to both sides to isolate 15x

15x = 210

→ Divide both sides by 15 to isolate x

x = 14

But we are not finished, the specifies us to find ∠MON and we have only found the value of x so we have to substitute x back into 8x - 13 to find the value of ∠MON

8x - 13

→ Substitute x = 14 back into into the expression

8 × 14 - 13

→ Simplify

112 - 13 = 99

So the value of ∠MON is 99°

Step-by-step explanation:

So

Total money = 20

Entrance fee = 1.75

Food = 2.50

Ride = 1.05

Amount spend = 1.75 + 2.05 = 3.8

Left for rides = 20 - 3.8 = 16.2

So rides = 16.2 ÷ 1.05 = 15

I think atleast 15 rides
