N is a 90 degree angle, M is an 30 degree angle, and L is a 60 degree angle

Answer:

The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

x+14= Vikings

x + x + 14 = 50 Combine the x's to be 2X

2x + 14 = 50 Subtract 14 from both sides

2x -14 = -14

2x = 36 Divide 2 into to 2x and 36

Total amount pay for potatoes = 50.2

Step-by-step explanation:

Given:

Levi buys cookies and potatoes

Total amount pay for cookies = 5.49

Total amount pay by Levi = 55.69

Find:

Total amount pay for potatoes

Computation:

Total amount pay for potatoes = Total amount pay by Levi - Total amount pay for cookies

Total amount pay for potatoes = 55.69 - 5.49

Total amount pay for potatoes = 50.2

Answer:

A

Step-by-step explanation:

hello :

8(e)^2x+1=4

(e)^2x+1=4/8 = 1/2

so : 2x+1 = ln(1/2)

2x = ln(1/2) - 1

x = (ln(1/2) - 1)/2

The solution to the given exponential function is x = [ ln(0.5) - 1]/2

The standard exponential equation is expressed as  y = ab^x

Given the expression

8(e)^2x+1=4

Divide both sides by 8

(e)^2x+1=4/8

(e)^2x+1 = 1/2

Take the ln of both sides

ln(e)^2x+1  ln(1/2)
2x + 1 = ln(0.5)

2x = ln(0.5) - 1
x = [ ln(0.5) - 1]/2

Hence the solution to the given exponential function is x = [ ln(0.5) - 1]/2

Answer:

10 cubic units

Step-by-step explanation:

I did the khan academy

The Volume of Pyramid B is 10 cubic unit.

A volume is just the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids.

The term "volume" refers to the amount of three-dimensional space occupied by an object or a closed surface.

We have,

Volume of A= 10 cubic units.

10 = 1/3 x B x5

B = 10 x 3/5

B = 2 x 3

B = 6 unit²

Now, volume of B

= 1/3 x 6 x 5

= 10 unit³

Answer:

[tex]\frac{16}{12} =1\frac{1}{3}[/tex]

[tex]1\frac{5}{8}= \frac{13}{8}[/tex]

let the price of pizza and soda( per 2 litre bottle) be x and y

from 1st condition

12x+2y=137.6.....(1)

from 2nd condition

x+y =11.95.......(2)

multiply eq. (2) by 2

2x+2y=23.9.....(3)

subtracting (1) and (3)

12x+2y=137.6

2x+2y= 23.9

10x = 113.7

x=113.7/10

x=11.37

2(11.37)+2y=23.9

22.74+2y=23.9

2y=23.9-22.7

2y=1.2

y=0.6

So the prices of  the pizza and soda are 11.37 and 0.6 dollars.

Each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

Let x be the cost of one pizza, and y be the cost of one 2-liter of soda.

According to the information given, we can write the following two equations:

1. For the pizza and soda purchased for the theater party:

12x + 6y = 137.64

2. For the pizza and soda purchased for Katya's family:

1x + 1y = 11.95

Now, we have a system of two equations with two variables. We can solve it to find the values of x and y.

First, let's solve the second equation for y:

y = 11.95 - x

Next, substitute this value of y into the first equation:

12x + 6(11.95 - x) = 137.64

Now, simplify and solve for x:

12x + 71.7 - 6x = 137.64

Combine like terms:

6x + 71.7 = 137.64

Subtract 71.7 from both sides:

6x = 65.94

Finally, divide by 6:

x = 65.94 / 6

x ≈ 10.99

Now that we have the value of x, which is the cost of one pizza, we can find the cost of one 2-liter of soda using the second equation:

y = 11.95 - x

y ≈ 11.95 - 10.99

y ≈ 0.96

So, each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

Answer:

[tex] \boxed{y = 10} [/tex]

Step-by-step explanation:

-12 = 6y + 18 – 9y

[Group like terms 6y and -9y]

-12 = (6y – 9y) + 18

[Simplify the expression]

-12 = -3y + 18

[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]

-12 = -3y + 18

–18 –18

-30 = -3y

[Divide by -3 from both sides, division property of equality, to get the variable y by itself]

-30 = -3y

÷(-3) ÷(-3)

10 = y
