Answer: 5/12

Step-by-step explanation:

Since the first customer bought 1/2 of the pan of brownies. This means that the pan of brownies left will be:

= 1 - 1/2

= 1/2

The The second customer bought 5/6 of what was left of the pan of brownies, the fraction that the second customer bought will be:

= 5/6 × 1/2

= 5/12

Answer:

5/12

Step-by-step explanation:

At a bake stall there is a large square pan of chocolate brownies. Customers can buy any fraction of the pan of brownies they like.

The first customer bought 1/2 of the pan of brownies.

The amount of brownies that was left over is given as:

1 - 1/2 = 1/2 brownies left ove

The second customer bought 5/6 of what was left of the pan of brownies.

The amount of brownies the second customers bought is calculated as:

5/6 of 1/2

= 5/6 × 1/2

= 5/12

What fraction of the whole pan did the second customer buy

Answer:

B. x = 65 because 109−44=65 and 44 + 65 = 109

Step-by-step explanation:

Given :

The triangle below :

Sum of interior angles of a triangle :

(44° + x + (180 - 109) = 180°

44° + x + 71° = 180

115° + x = 180°

x = 180° - 115°

x = 65°

Answer:

$1.5

Step-by-step explanation:

This would be solved using a simultaneous equation

let tacos = t

drink = d

3t + d = 7 -- eqn 1

2t + 2d = 8 -- eqn 2

Multiply equation 1 by 2 to derive equation 3

6t + 2d = 14 eqn 3

Substract equation 2 from equation 3

6t + 2d = 14 -- eqn 3

         -

2t + 2d = 8 -- eqn 2

= 4t = 6

solve for t

6/4 = 1.5

= $1.5

Answer:

Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.

Answer:

Distance between the plane and the observer is 511.86 miles.

Step-by-step explanation:

From the figure attached,

A plane is flying at point A which is at 200 m height and observer is at point C.

Angle of elevation (∠ACB) of the plane from the observer is 23°.

Let the distance between the observer and the plane is x meters.

By applying sine ratio for angle C,

sin(∠C) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(23°) = [tex]\frac{200}{x}[/tex]

x = [tex]\frac{200}{\text{sin}(23)}[/tex]

x = 511.86 miles

Therefore, distance between the plane and the observer is 511.86 miles.

Answer:

17

Step-by-step explanation:

(7, 8)  (-8, 0)

First find how much the point moved in y to the second point.

8-0=8

So one side is 8.

Then find how much it moved in x. 7-(-8)=15

So the other side is 15

This will give you 2 sides of a triangle where one sides lenght is 8 the other is 15. Use the pythagoras theorem which is x squared plus y squared = c squared

8^2+15^2=c^2

64+225=c^2

289=c^2 Take the square root of both sides to solve for C

√289= √C^2

17 = c

Answer:

6a^3 + 5a^2 - 6a - 2

Step-by-step explanation:

(4a^3 + 5a^2 - a + 1) - (5a - 2a^3 + 3)

Combine like terms

4a^3 - (-2a^3) = 6a^3 (- times - = +)

-a - 5a = -6a

1 - 3 = -2

Now combine the answers in standard form (don't forget the 5a^2)

6a^3 + 5a^2 - 6a - 2

Answer:

y = 6

Step-by-step explanation:

3 y - x = 9

y = (2 x)/3

Substitute y = (2 x)/3 into the first equation:

{x = 9

y = (2 x)/3

Substitute x = 9 into the second equation:

Answer:

x = 9

y = 6

Answer:

[tex]8.2 * 10^{-3}[/tex] is the greatest

2000 times greater

Step-by-step explanation:

Given

[tex]8.2 * 10^{-3}[/tex]

[tex]5.2 * 10^{-6}[/tex]

[tex]4.1 * 10^{-6}[/tex]

Solving (a): The greatest of the numbers

First, we convert them to decimals:

[tex]8.2 * 10^{-3} = 0.0082[/tex]

[tex]5.2 * 10^{-6} = 0.0000052[/tex]

[tex]4.1 * 10^{-6} = 0.0000041[/tex]

By comparing the decimal numbers, the highest is: 0.0082.

Hence,

[tex]8.2 * 10^{-3}[/tex] is the greatest

Solving (b): How many times greater than the smallest

In (a) above:

The greatest is: [tex]8.2 * 10^{-3}[/tex]

By comparing the decimal numbers,

The smallest is: 0.0000041 i.e. [tex]4.1 * 10^{-6}[/tex]

The number of times the greatest is greater than the smallest is:

[tex]Number = \frac{8.2 * 10^{-3}}{4.1 * 10^{-6}}[/tex]

[tex]Number = \frac{0.0082}{0.0000041}[/tex]

[tex]Number = 2000[/tex]

Hence, it is 2000 times greater

Answer:

6

Step-by-step explanation:

Degree of a polynomial is the degree of the monomial with the greatest degree, which in this case is 6x^6, so the degree of this polynomial is 6 because the x is raised to the 6th degree.

The degree of the polynomial 5x⁵-6x⁶ + 2 is 6.

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given:

The polynomial,

5x⁵-6x⁶ + 2.

Here, we have the variable x.

And the highest power of a variable is a degree of a polynomial.

So, the degree of polynomial is 6.

Therefore, the degree of the polynomial is 6.
