The graph shows the distance a car traveled, y, in x hours:

meriva

Answer:

The correct answer is 30

Step-by-step explanation:

Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.

The line passes through the points $(2,60)$ and $(4,120)$

To find: The rise-over-run value for the relationship in the graph.

$\begin{aligned}m &=\frac{R i s e}{R u n} \\&=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\&=\frac{120-60}{4-2} \\&=\frac{60}{2} \\&=30\end{aligned}$

Thus, the rise-over-run value for the relationship represented in the graph is 30.

Simplify. (–8x) ÷ (–4)

vovikov84 [41]

(-8x)<span> ÷ (-4)=0
First you have to divide both sides by -4:
2x</span><span> ÷ 1=0
Now divide both sides by 1 so that the left side can be eliminated:
2x=0
</span>Now divide both sides by 2 so that the left side only has x:
x=0

It is given that parallelogram JKLM is a rectangle and by the definition of a rectangle, ∠JML and ∠KLM are right angles. ∠JML≅∠K

Andru [333]

Answer:

all right angles are congruent.
opposite sides of a parallelogram are congruent
SAS congruence postulate
corresponding parts of congruent triangles are congruent

Step-by-step explanation:

Given : Parallelogram JKLM is a rectangle and by the definition of rectangle, $\angle{JML}=\text{ and }\angle{KLM}$ are right angles,

Since all interior angles of rectangle are right angle.

then $\Rightarrow\angle{JML}\cong\angle{KLM}$ , because all right angles are congruent.

Also, opposite sides of a parallelogram are congruent.

$\overline{JM}\cong\overline{KL}$

and $\overline{ML}\cong\overline{ML}$ by the reflexive property of congruence.

Now, by the SAS congruence postulate,

$\triangle{JML}\cong\triangl{KLM}$ ,

Since corresponding parts of congruent triangles are congruent, ∴

$\overline{JL}\cong\overline{MK}$

The SAS postulate says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle then the two triangles are congruent.

What is the volume of this oblique cone? 12π cm³ 40π cm³ 60π cm³ 120π cm³ An oblique cone with radius of six centimeters and hei

Pepsi [2]

We have to find the volume of oblique cone. An oblique cone is a special type of cone in which the apex is not located directly above the center of the circular base, so it looks like a slanted cone.

Volume of oblique cone = $\frac{1}{3} \Pi r^{2}h$
