Answer:
1) x = 29; m∠3 = 6º
2a) scalene
2b) acute
Step-by-step explanation:
1) We can first solve for m∠3, as it is supplementary to 174º.
174º + m∠3 = 180º
m∠3 = (180 - 174)º
m∠3 = 6º
Then, we can solve for x by setting the sum of the measures of the interior angles of the triangle to 180º.
m∠1 + m∠2 + m∠3 = 180º
↓ substitute in given and solved values
(3x + 2)º + (5x - 60)º + 6º = 180º
↓ combine like terms
8xº - 52º = 180º
↓ add 52 to both sides
8xº = 232º
↓ divide both sides by 8º
x = 29
2a) We know that this triangle is not equilateral, as the measure of one of its interior angles (m∠3) is 6º. However, the triangle may be isosceles if m∠1 = m∠2. We can check for that by substituting x into each angle measure expression.
m∠1 ≟ m∠2
(3x + 2)º ≟ (5x - 60)º
↓ substitute in x-value
3(29)º + 2º ≟ 5(29)º - 60º
↓ simplify
(87 + 2)º ≟ (145 - 60)º
89º ≠ 85º
m∠1 ≠ m∠2; the triangle is not isosceles. Therefore, it must be scalene.
2b) All of the triangle's angles are less than 90º. Hence, it is an acute triangle.

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1256.00 square feet? Use 3.14 for pi
Answers
Answer:
20 feet
Step-by-step explanation:
A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1256.00 square feet? Use 3.14 for pi
From the above question, we are to find the radius of the circular pattern
The formula for the Area of the circle = πr²
To find r
r² = A/π
r = √A/π
In the above question, Area = 1256 square feet
π = 3.14
r = √1256/3.14
r = √400
r = 20 feet
The radius/distance from the sprinkler that can spread water = 20 feet
Matt made a trip to his friend's house and back. On
the trip there he drove 24 miles per hour and on the
return trip he went 30 miles per hour. How long did
the trip there take if the return trip took 4 hours
Answers
24 mph (? hour trip there)
<————
30 mph (4 hour return trip)
If the return trip took 4 hours, then that means the total miles away would be 120. Matt was driving at 30 mph and drove for four hours, After multiplying 30 by 4, you will get 120. Once you’ve done that, you can do 120 divided by 24. Now that you know how many miles away his friend’s house is, you can estimate the time it took him to arrive by driving at 24 mph. 120 / 24 = 5
Answer: 5 hours

Intr un album numarul de fotografii s a micsorat cu 50%. Cu cat trebuie sa se mareasca pentru a reveni la numarul initial? Raspunsul trebuie sa fie 100%.
Answers
Răspuns:
100%
Explicație pas cu pas:
Permiteți numărul inițial de fotografii = x
x - 50% din x = x - 0,5x = 0,5x
0,5x + câte% din 0,5x = x
x - 0,5x = y% de 0,5x
0,5x / 0,5x = 1
Prin urmare,
100% = 1
Prin urmare, x trebuie mărit cu 100% pentru a reveni la numărul original.

Step-by-step explanation:
Based in the tangent-secant theorem,
KI*JI = HI²
KI = (x + 0.5)
JI = 0.5
HI = 1
Plug in the values
(x + 0.5)(0.5) = 1²
0.5x + 0.25 = 1
0.5x = 1 - 0.25
0.5x = 0.75
x = 0.75/0.5
x = 1.5

Mr. Wedmore brought in $10,000 worth of profit
for the dealership, how much would he earn this
month?
Answers
Answer: $2,000. + 25% + $10,000= 12,500 Or $2,000. - 25% - $10,000=8500
Step-by-step explanation:
Answer: $4,500
Step-by-step explanation: First, the monthly salary is $2,000 so this is part of the total already. The 25% commission is on the profit they earn and the profit they earned was $10,000. To find 25% of $10,000, you do 10,000 times 0.25 which is $2,500.
Total Earned: $2,000 (Monthly Salary) + $2,500 (Commission Amount) = $4,500

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given that a 45-foot ladder is set against the side of a house so that it reaches up to 27 feet. If Latanya grabs the ladder at its base and pulls it 3 feet farther from the house.
The distance will be calculated as,
a² + b² = c²
a² + (39)² = 45²
a² = 45² - 39²
a=√504
a = 22.4 ft
Therefore, the side of the ladder from the house will be 22.4 ft far.

Answer:
The number of tickets purchased typically varies from the expected value by 0.95 tickets.
Step-by-step explanation:
The standard deviation of the distribution is 0.95.
What is Standard Deviation?The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.
We have
P (X = 1)= 0.29
P (X = 2) = 0.44
P( X= 3) = 0.19
P (X = 4) = 0.06
P (X = 5) = 0.02
The expected value is given by the sum of each value multiplied by it's respective probability, hence:
E(X) = 0.29(1) + 0.44(2) + 0.19(3) + 0.06(4) + 0.02 (5)
E(X) = 2.08
As, The standard deviation is the square root of the total of the difference squared between each value and the mean, multiplied by the likelihood of each value.
[tex]\sigma[/tex] = √0.29 (1- 2.08)² + 0.44(2- 2.08)² +.....+ 0.02 (5- 2.08)²
= 0.95
Thus, the standard deviation is 0.95.
