Answer:

Yes.

Step-by-step explanation:

We know <S is congruent to <U. line segment ST is congruent to line segment UT. Also, the line going through T( line segment RV) makes 2 congruent angles. <STU and < UTV are congruent. So triangle RST is congruent to triangle VUT by ASA (angle side angle.)

The mean daily rainfall for a week was 5.5mm.for the first six days the mean rainfall was 1mm.How much rainfall on the seventh d
spayn [35]

Answer:

There was 32.5mm of rainfall on the seventh day.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all values of a data-set divided by the number of values in the data-set.

The mean daily rainfall for a week was 5.5mm.for the first six days the mean rainfall was 1mm.

This means that during the week(7 days), the total amount of rain was of:

6*1 + x = 6 + x

How much rainfall on the seventh day ​?

This is x. We have that:

\frac{6 + x}{7} = 5.5

6 + x = 7*5.5

6 + x = 38.5

x = 38.5 - 6 = 32.5

There was 32.5mm of rainfall on the seventh day.

Find the volume of each cone.​
umka2103 [35]

Answer: 6 cm, V=48π or V=150.8 cm³

It appears the question is asking for the radius, but below I have shown how to find the volume.

Step-by-step explanation:

The radius is half of the diameter. The diameter of the cone of 12 cm. Half of 12 is 6. Therefore, the radius is 6 cm.

The formula to find the volume of a cone is V=\pi r^2\frac{h}{3}. Now that we have the radius from above, we can use that to plug into the equation along with the given height.

V=\pi (6^2)\frac{4}{3}                    [expand the exponent]

V=36\pi \frac{4}{3}                       [combine like terms]

V=48\pi or V=150.8 cm^3
