Answer:

if ABCD is a rhombus then the diagonal of rhombus bisect it into two equal triangles.

Step-by-step explanation:

In triangles ABC and CDA,

AB= CD (S) because rhombus has equal sides.
BC = AD (S) as as reason 1.
AC= AC (S) being common side of both triangles

so the triangles are congruent to each other by S.S.S. fact/ axiom

It's D.30 because 600 divided by 20 is 30 or u can multiply 30 x 20 = 600.

Judy spent 3 hours driving 165 miles She thinks

sasho [114]

Step-by-step explanation:

she drove already 165 miles.

she will reach her destination, if she drives 4 more hours by going 65 miles/hour.

that would mean she would travel

65×4 = 260 miles

in these 4 hours.

so, the total trip is then 165 + 260 = 425 miles.

but what I find strange is that your teacher specified how long it took her to drive the first 165 miles.

as you can see above, it would make no difference for the calculation of the total trip length in miles.

this is either an attempt to confuse us, or the message is that Judy has to achieve an average of 65 miles/hour for the whole trip, and the problem definition was just imperfectly phrased.

if that is the case, then things look a bit different, as her average speed was only 165/3 = 55 miles/hour for the first 3 hours and 165 miles.

so,

(165 + x)/(3 + 4) hours = 65/hour

(165 + x)/7 hours = 65/hour

165 + x = 65 × 7 hours / hour = 65×7 = 455 miles

x = 455 - 165 = 290 miles

she would have to go

290 miles / 4 hours = 72.5 miles/hour

for these next 4 hours (and 290 miles) to reach an overall average speed of 65 miles/hour.

and the total trip would be then

165 + 290 = 455 miles

I am not sure, which your teacher wants here.

65 miles/hour average speed just for the next 4 hours, or to speed up that much for the next 4 hours that the overall trip average is then 65 miles/hour.

again, the phrasing of the problem definition suggests the first case, but the fact that the travel time for the first part of the trip is given could suggest the second case (as this information is not needed for the first case).

Which function has the graph shown?

balu736 [363]

Answer:

y = csc(x) -1

Step-by-step explanation:

The vertical offset of -1 is your first clue. Your second clue is that the range does not include (-2, 0), typical of cosecant and secant functions (offset by -1).

_____

<em>Comment on answer choices</em>

Apparently the cosine choices are intended to be confused with the cosecant choice. The cosine function has a range of [-1, 1], so will not show any vertical asymptotes anywhere, regardless of scaling or translation.

Help please find the volume of the sphere

borishaifa [10]

Answer: 44.6cm³

The formula is $\frac{4}{3} \pi r^3$ .

Since the formula had π (pi) pi is 3.14.

The radius is the line inside the sphere.

That being said, the radius is 2.2, so the line is 2.2 long.

Now, let's solve.

4/3 × 3.14 = 4.186 → 4.19

4.19 × 2.2³ = 44.6

Hence, 44.6 is the answer.
