Answer:

18

Step-by-step explanation:

Area = base x height

So you would start by multiplying you 2 side lengths given:

Area = 2 sqrt 3 x sqrt 27

2 sqrt 3 x sqrt 27 = 18

Once multiplied, you will get you area. Which is 18 units squared.

Step-by-step explanation:

Since X : Y = 1 : 2, X = 0.5Y.

Since Y : Z = 2 : 5, Z = 2.5Y.

We have X + Y + Z = 4Y = 40. Hence Y = 10.

[tex]y=10[/tex]

Given -

[tex]x+y+z=40\\x:y=1:2\\y:x=2:5[/tex]

To find - [tex]y[/tex]

Since,

[tex]x:y=1:2,x=0.5y\\y:x=2:5,z=2.5y\\x+y+z=4y+40\\y=10[/tex]

Therefore, [tex]y=10[/tex].

Since $14 is the price after a 30% discount then $14 is 70% of the original price.

$14/70=x/100 (100% would be the original price)

1400=70x or 1400/70 = $20!

You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!

Answer:

86 heartbeats per minute

Step-by-step explanation:

i assume that's your question?

the number of heartbeats per minute is 86.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 473 heartbeats in [tex]5\frac{1}{2}[/tex] = 11/2minutes

Number of heart beats per minute = Total number of heart beats ÷ Number of minutes

= 473÷ 11/2

= 473×2/11

= 43×2

= 86 beats per minute

Therefore, the number of heartbeats per minute is 86.

Answer:

option 1 is the answer because both of the equations are same

Answer:

(3, 2)

Step-by-step explanation:

Answer:

you find the point where the line intersects

Given:

A figure.

To find:

The values of x and y.

Solution:

We know that, in a right angled triangle,

[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin 60^\circ =\dfrac{x}{16}[/tex]

[tex]\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16[/tex]

[tex]8\sqrt{3}=x[/tex]

And,

[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos 60^\circ =\dfrac{y}{16}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{16}{2}=y[/tex]

[tex]8=y[/tex]

Therefore, the missing side lengths are [tex]x=8\sqrt{3}[/tex] and [tex]y=8[/tex].

[tex]5x^2-5x-6x+6[/tex]

Step-by-step explanation:

[tex]5x^2-11x+6\\5x^2-5x-6x+6[/tex]

we need to factorize it so the X-term expanded should satisfy two conditions

1) +5 times +6 should be +30

2) add or subtract any two numbers which multiply and give -11

so here -5 times -6 gives +30 and -5 added to -6 equals -11

Answer:

[tex]k = -\frac{1}{5}[/tex] -- Constant

[tex]y = -\frac{x}{5}[/tex] -- Equation

Step-by-step explanation:

Given

[tex]\{(-15, 3), (-5, 1), (0, 0), (10, -2)\}[/tex]

Solving (a): The constant of variation

The given parameter is of the form (x,y) and the variation constant is calculated using:

[tex]k = \frac{y}{x}[/tex]

For:(-15,3), k is calculated as

[tex]k = \frac{y}{x}[/tex]

[tex]k = \frac{3}{-15}[/tex]

[tex]k = -\frac{1}{5}[/tex]

For (-5,1)

[tex]k = \frac{y}{x}[/tex]

[tex]k = \frac{1}{-5}[/tex]

[tex]k = -\frac{1}{5}[/tex]

The equation is calculated using the following rule:

[tex]y = kx[/tex]

Substitute [tex]-\frac{1}{5}[/tex] for k

[tex]y = -\frac{1}{5} * x[/tex]

[tex]y = -\frac{x}{5}[/tex]

Answer:

well, 11 days

Step-by-step explanation:

if you were to put take out the y and put 2600 in the y place (2600=235x+15)

you solve that, and will come to 11 days

further explaining:

2600-15 = 2585

2585 / 235 = 11

( I'm not sure if this is right, the question is worded weird and almost doesn't make sense)

but I think it is looking for substitution

Hope this helps!

Answer:

I am given a number of cans, which is y, and I need to find the number of days, which is x. To do this, I would substitute 2600 for y, to get 2600 = 235x + 15. Solving for x, I would get x = 11. Thus, it would take 11 days to collect 2600 cans.

Answer:

4n+2 (B)

Step-by-step explanation:

Answer:

the answer is b

Step-by-step explanation:

because the value of terms are going up by 4 every time, so if you subtract 4 you get 2 and the position would be 0 making 2 the y-intercept and then slope is= rise/run and the equation is rising 4 units for every 1 unit moved, so the slope is 4/1 or 4. plug all of that into the equation and you get 4n + 2

Answer:

Answer:

48

Step-by-step explanation:

Vertical angles are congruent

7x - 22 = 4x + 8     {Add 22 to both sides}

         7x = 4x + 8 + 22

        7x = 4x + 30         { subtract 4x from both sides}

7x - 4x = 30

         3x = 30

           x = 30/3

x = 10

4x + 8 = 4*10 + 8

          = 40 + 8

          = 48

7x - 22 = 7*10 - 22

            = 70 - 22

            = 48

Answer:

First angle = 117 degrees.

Second angle = 63 degrees.
