Answer + Step-by-step explanation:

For y = x - 3 points are: (0,-3) , (3,0)

For y = 2x + 1 points are (0,1) , (- $\frac{1}{2}$ ,0)

For y = $\frac{x}{2}$ - 2 points are (0,-2) , (4,0)

For y = $\frac{x - 3}{3}$ points are (0,-1) , (3,0)

1. Eyeballing the data, the best fit will be pretty close to a line between the leftmost point and the rightmost point.

We estimate those points as (4,220) and (28,470)

The point point form for a line joining (a,b) and (c,d) is

(c-a)(y-b) = (d-b)(x-a)

(28 - 4)(y - 220) = (470 - 220)(x - 4)

24(y - 220) = 250(x-4)

24y - 5280 = 250x - 1000

24y = 250 x + 4280

y = (250/24) x+ (4280/24)

Approximately that's,

y = 10.4 x + 178

Answer: 4th choice, 10.4x + 180

2. For 48 wheelbarrows,

y = 10.4(48)+180 = 679.2

Answer: 679.2 liters of sand

Plz help if you can Thank ya

Answer:

$90\pi$

Step-by-step explanation:

The first step is to find the slant height of the cone. Using the pythagorean theorem, you can find that $\sqrt{12^2+5^2}=13$ cm. Plugging this into the equation, you get $\pi \cdot 5 \cdot 13=90\pi$ . Hope this helps!

Answer:

$\frac{y^7z^3}{x}$

Step-by-step explanation:

When variables have negative exponents, switch their positions.

$\frac{x^{-1}y^7}{z^{-3}}=\frac{y^7z^3}{x}$

Answer: The perimeter is 17.52

Step-by-step explanation:

1. You can plot the points, as you can see in the graph attached.

2. As you can see in the graph, the points are:

$A(-2,-2)\\B(-2,3)\\C(2,4)\\D(3,1)\\E(0,-2)$

And the lenghts AB and EA are:

$AB=5$

$EA=2$

3. To find the other lenghts, you can apply the formula for calculate the distance between two points:

$distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

4. Thefore, you have:

$BC=\sqrt{(2-(-2))^{2}+(4-3)^{2}}=4.12\\CD=\sqrt{(2-3)^{2}+(4-1)^{2}}=3.16\\DE=\sqrt{(3-0)^{2}+(1-(-2))^{2}}=4.24$

5. The perimeter is:

$P=AB+CD+DE+EA\\P=5+4.12+3.16+4.24+2\\P=17.52$

Answer:

$-\dfrac{3}{5}$

Step-by-step explanation:

1. Find the numerator:

$\dfrac{1}{3}-\dfrac{5}{6}=\dfrac{1\cdot 2}{3\cdot 2}-\dfrac{5}{6}=\dfrac{2}{6}-\dfrac{5}{6}=\dfrac{2-5}{6}=-\dfrac{3}{6}=-\dfrac{1}{2}.$

2. Simplify the fraction:

$\dfrac{-\frac{1}{2}}{\frac{5}{6}}=-\dfrac{1}{2}\cdot \dfrac{6}{5}=-\dfrac{3}{5}.$
