Answer:

$1.6

Step-by-step explanation:

We need to find the cost of 80 cm of copper pipe at $2 a metre.

Cost of 1 metre = $2

80 cm = 0.8 m

It means,

0.8 m = $2 × 0.8

= $1.6

So, the cost of 80 cm of copper pipe is equal to $1.6.

Answer:

2.3

Step-by-step explanation:

First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)

Answer:

y = 2x-3

Step-by-step explanation:

The y intercept is -3. The slope is change in y/change in x. 2/1 = 2

Answer:

x=72 degrees

Step-by-step explanation:

180-108=72

it is 180 because a straight angle is 180 degrees.

then you subtract 108, which is an alternate interior angle, to get 72, which is an alternate exterior angle.

Answer:

x=72

Step-by-step explanation:

Since the whole angle is 180 you have to do 180-108 which you get 72.

Then since x and 72 are vertical angles they have to be the same so x=72

Answer:

Equation 2: x - 2y = 1

Step-by-step explanation:

The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true.  Furthermore, if you substitute a 0 for y you automatically know that x = 1.

If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.

Answer:

A combined mean is simply a weighted mean, where the weights are the size of each group. For more than two groups: Add the means of each group—each weighted by the number of individuals or data points, Divide the sum from Step 1 by the sum total of all individuals (or data points).

Step-by-step explanation:

192 cm²

Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .

According to Pythagoras Theorem :-

=> base² + perpendicular ² = hypontenuse ²

=> 12² + x² = (x+4)²

=> 144 + x² = x² + 16 + 8x

=> 8x = 144-16

=> 8x = 128

=> x = 128/8

=> x = 16 cm .

Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.

= 1/2 * 16 cm * 24cm .

= 192 cm²

Answer:

r=0

Step-by-step explanation:

1) Place point (2, 3) on graph.

2) Use the slope of -1 to go left -1 and go down -1

3) Until you get to x value of -1

Answer:

SAS because there is only one angle but there are two sides

Answer:

A

Step-by-step explanation:

For the function y = f(x), a reflection in the y axis is y= f(-x)

(-x)^3 = -x^3 so negate that term

(-x)^2 = x^2 so leave that as is

(-x)^1 = -x so negate that term too

Answer:

x=7

Step-by-step explanation:

Answer:

x = 7

Step-by-step explanation:

Given

2x + 2 = x + 9 ( subtract x from both sides )

x + 2 = 9 ( subtract 2 from both sides )

x = 7

Answer:

B. E'(-1,1)

Step-by-step explanation:

Change the X value of each of the points by -5, as this represents 5 units left.

Change the Y value of each of the points by +2, as this represents 2 units up.

For E:

X: 4 - 5 = -1

Y: -1 + 2 = 1

Coordinate: (-1,1)

Answer:

g(f(x)) = -x^2 + x - 15

Step-by-step explanation:

g(f(x^2 - x + 11) = -1 * (x^2 - x + 11) - 4 = -x^2 + x - 11 - 4 = -x^2 + x - 15

Answer:

10 for x and y

Step-by-step explanation:

Because the triangle adds up to 30 deggrees

So... you want to take 4 out.

30- 4 = 24

Than...You want to divided 24 by 2.

And that equals 12

Than round 12's by tenth

Which equals 10
