What is the value of x?360x = [?]​

Mathematics
1 answer:
atroni [7]2 years ago
7 0

Answer:

<h2>x = 54</h2>

Step-by-step explanation:

The line is tangent. Therefore, the angle between the tangent and the radius is the right angle.

We know: the sum of the angles measures in a triangle is 180°.

Therefore we have the equation:

x+36+90=180          <em>combine like terms</em>

x+126=180            <em>subtract 126 from both sides</em>

x=54

Hi!
Alrighty, so there are 5 sets of 50 in 250 (250 divided by 50), so just take 50 times 12 and get 60! Hope that helped :)

3. The table shows the number of hours that a grouped of students spent studying for the SAT during their first week of preparat
laiz [17]
The answer is the mean, mode, and median increases by 4, the range of times is the same.

Week 1:                                              Week 2:
Student - Hours                                 Student - Hours<span>
Bob          19                                       </span>Bob          23<span>
James      10                                      </span>James       14<span>
Karen       15                                       </span>Karen       19<span>
Rosario    17                                        </span>Rosario    21<span>
Antoine    10                                       </span>Antoine    14<span>
Julio         16                                       </span>Julio         20<span>
Maria        13                                       </span>Maria        17<span>

The mean is the sum of all values divided by the number of values:
Week 1: (19 + 10 + 15 + 17 + 10 + 16 + 13)/7 = 100/7 = 14.28
Week 2: (23 + 14 + 19 + 21 + 14 + 20 + 17)/7 = 128/7 = 18.28
The difference in means between Week 2 and Week 1 is 4 (18.28 - 14.28 = 4)

The median is the middle value. To calculate, first rearrange values from the lowest to the highest and then find the middle value:
Week 1: 10, 10, 13, 15, 16, 17, 19            - The median is 15.
Week 2: 14, 14, 17, 19, 20, 21, 23          - The median is 19.
The difference in medians between Week 2 and Week 1 is 4 (19 - 15 = 4)

The mode is the value that occurs most frequently.
</span>Week 1: 10, 10, 13, 15, 16, 17, 19            - The mode is 10.
Week 2: 14, 14, 17, 19, 20, 21, 23          - The mode is 14.
The difference in modes between Week 2 and Week 1 is 4 (14 - 10 = 4)

The range of times is the difference between the highest and the lowest value.
Week 1: 10, 10, 13, 15, 16, 17, 19            - The range of times is 9 (19 - 10 = 9).
Week 2: 14, 14, 17, 19, 20, 21, 23          - The median is 9 (23 - 14 = 9).
The difference in the ranges of times between Week 2 and Week 1 is 0 (9 - 9 = 0)

Jasmine purchased a laptop worth $1,500 in 2007. It loses its value by %32 each year. What is the value of the laptop in 2010? R
Lunna [17]

Answer:

$471.65

Step-by-step explanation:

-The value of the laptop after each year is calculated by the formula:

P_t=P_o(1-d)^t

where:

P_t is the value at time t

P_o is the initial value

d is the rate of depreciation

t is the time

#We substitute the values to solve for the value after 3 years(2010-2007=3):

P_t=P_o(1-d)^t\\\\=1500(1-0.32)^3\\\\=\$471.65

Hence, the value of the laptop in 2010 is $471.65
