The answer is 95
Angles ∠UTS and <span>∠URS are equal = 120
The parallelogram is 360 degrees so,
360-120= 240
240 is both </span>∠RST and <span>∠RUT so divide it by 2= 120
</span>∠UST= ∠RST-<span>∠USR 
</span><span>∠UST= 120-25
</span><span>∠UST= 95</span>

Answer:

∠UST = 95°

Step-by-step explanation:

In the given parallelogram,

Sides RS and UT are parallel and SU is transverse.

So, ∠RSU ≅ ∠SUT ≅ 25° [Alternate angles]

We know sum of all angles in a triangle is 180°.

Therefore, in ΔSUT,

∠UST + ∠STU + ∠TUS = 180°

∠UST + 60° + 25° = 180°

∠UST + 85° = 180°

∠UST = 180° - 85°

∠UST = 95°

Therefore, ∠UST = 95° will be the answer.

Answer:2. Both the populations of the Candy Kingdom and the Fire Kingdom are in decline; their populations

since 2010 are given by the functions below:

Cit) 1000 - 500

F(t) = 2500 - 1000

Will their populations ever be equal? If so, when will that happen and what will that population be?

Otherwise, briefly explain why their populations will never be equal.

Describe the sample variance using words rather than a formula. do the same with the population variance
Korvikt [17]

The option D is the correct option.

According to the statement

we have to define the sample variance in the words.

So,

The sample variance is the sum of the squared deviations from the mean divided by the number of measurements minus one.

and in the case of the population variance it becomes

The population variance is the average of the squared distances of the measurements on all units in the population from the mean.

This is the method by which we define the sample variance and population variance.

So, The option D is the correct option.

Solving multi step equations 5/6k + 2/3 = 4/3
Tpy6a [65]

Answer:

k = 4/5

Step-by-step explanation:

First, rewrite 5/6k as (5/6)k; this is "five sixths of the variable k."

Next, identify the LCD.  It is 6.  Then the given equation becomes

5k + 4 = 8

Consolidate the constant terms:  

5k = 4

Solve for k: k = 4/5
