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:

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: 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:

y = 6

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:

$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:

-12x + -4y = 8 would be the full equation so -12x goes in the box

Answer:

8.46 years

Step-by-step explanation:

Given data

P=$3100

R= 3%

A= $4000

Calculate time, solve for t

t = ln(A/P) / r

substitute

t=ln(4000/3100)/3

t=ln1.290/0.03

t= 0.254/0.03

t= 8.46

Hence the time is 8.46 years

Answer:

48

Step-by-step explanation:

16+32=16(1+2)=16(3)=48

16 + 32 as product of two factors = 16 × 3

A factor is a number that divides another number completely with no remainder. Factors and multiples are related concepts in math.

Given expression,

16 + 32

It can be written as

4 × 4 + 4×4×2

Greatest common factor = 4×4 = 16

16(1) + 16(2)

Using Distributive property, factoring out the GCF

16 (1 + 2)

16 × 3

Hence, 16 × 3 is the product form of 16 + 32.

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: 12 miles

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: 4 ( x − 3 ) ( x + 3 )

Step-by-step explanation:

The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

Answer:

Below.

Step-by-step explanation:

2x - 6 = 2(x - 3)

4x + 12 = 4(x + 3)

x^2 - 9 = (x - 3)(x + 3)

So the LCM is:

4(x - 3)(x + 3)

or 4x^2 - 36.
