Answer:I think its 68
Step-by-step explanation:
Answer:
The measure of angle N is 68 degrees.
Step-by-step explanation:
Since this shape is a parallelogram, opposite angles will be equivalent. So to start, set (6x - 2) equal to (4x + 36).
— 6x - 2 = 4x + 36
Next, subtarct the 4x from both sides of the equation as well as add 2 to both sides of the equation an simplify.
— 6x - 4x - 2 + 2 = 4x - 4x + 36 + 2
— 2x = 38
Now, divide both sides of the equation by 2 to find the value of x.
— 2x/2 = 38/2
— x = 19
Finally, substitute 19 for every x in the original equation. Simplify.
— 6(19) - 2 = 4(19) + 36
— 114 - 2 = 76 + 36
— 112 = 112
We now know that these two angles are 112 degrees. If a parallelogram's angles must add up to 360 degrees, then subtract 112 twice from 360 to find the combined total angle measure of N and Q. Then divide that number by 2 to find the measure of N.
— 360 - 112 - 112 = 136
— 136/2 = 68
The measure of angle N is 68 degrees.

Which ratio is equivalent to 1:3 and 12:36? (A) 2:18 (B) 4:9 (C) 4:12 (D) 6:6
Answer:
I think the right answer is c 4:12
Answer:
(C) - C for Correct!
Step-by-step explanation:
We can look at ratios as a fraction, so 1:3 = 1/3 and 12:36 = 12/36. We can simplify the second fraction into 12/36 = 1/3 by canceling 12 from the numerator and denomerator. We can do this with all of the answer choices:
(A) Wrong - 2/18 = 1/9
(B) Wrong - 4/9
(C) Correct - 4/12 = 1/3
(D) Wrong - 6/6 = 1

Car x travels 162 miles in 3 hours: write an equation of the line that describes the relationship between distance and time. Use x for the time in hours and y for the distance in miles
Answer:
A:The equation y=54x describes the relationship
B: y as 216 and x being 4
If a car travels for 0 hours, it will travel 0 mile(s). This means it will pass through the point (0,0)
.Use the slope to move 3 units to the right of the origin and
162 unit(s) up to find the point
(3,162) that can be used to graph the relationship. Step-by-step explanation:

A group of 8 students was asked, "How many hours did you watch television last week?" Here are their responses: 7, 14, 12, 13, 14, 6, 9, 16 Find the mean and median number of hours for these students. If necessary, round your answers to the nearest tenth.
Answer:
11.4- average
12.5 - median
Step-by-step explanation:
AVERAGE:
Add them up and divide by 8
MEDIAN:
1. Arrange the set from least to greatest.
6,7,9,12,13,14,14,16
2. Start from the first and last numbers and cross them out until you are left with the 2 in the middle. If there was an odd set of numbers, you would end up with one number.
7,9,12,13,14,14
9,12,13,14
12,13
3. Add the remaining two numbers and divide by 2.
12+13/2 = 12.5

Answer:
The amount of acid in the solution will be: 55.4 millimeters
Step-by-step explanation:
The total amount of solution of acid and water = 342 milimeters
The percentage of acid included in the solution = 16.2%
The amount of acid in the solution:
[tex]16.2\%\:\times 342[/tex]
[tex]=\frac{16.2}{100}\times \:342[/tex]
[tex]=\frac{162}{1000}\times \:342[/tex]
[tex]=0.162\times \:342[/tex]
[tex]=55.4[/tex] millimeters
Thus, the amount of acid in the solution will be: 55.4 millimeters
Solve the equation - [tex]\frac{w}{5}[/tex] +9=13. What is w?
Answer:
w = -20
Step-by-step explanation:
-[tex]\frac{w}{5}[/tex] + 9 = 13
Shift the (+9) to the other side of the equation. (+9) will turn into (-9).
-[tex]\frac{w}{5}[/tex] = 13 - 9
= 4
Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).
-w = 4 × 5
= 20
Multiply both sides of the equation by (-1) so that -w will turn into w.
w = (-1) × 20
w = -20
I know the answer is 36 but I need to know the working out and I am unsure how to work the question out.
Plz explain
Thanks in advance!! :)
Answer:
36
Step-by-step explanation:
Since the 3 numbers have a ratio of 2:3:7, that means it simplifies to that. So, there must be a common factor, let’s say x, for each of the numbers. Thus, the numbers are 2x, 3x, and 7x. To find the mean, we add up all of the numbers and divide by the number of numbers: (2x + 3x + 7x)/3 = 12x/3 = 4x = 48. Dividing by 4 on both sides gets x = 12. The median of the numbers is the number in the middle which is 3x. Substituting x = 12, we get: 3(12) = 36.
I hope this helps!!! :)
Afla suma a trei numere ,stiind ca primul este succesorul numarului 999 ,al doilea este cu 1.872 mai mare ,iar al treilea cat primele doua la un loc.
Answer:
7744
Step-by-step explanation:
Din informațiile furnizate:
Succesorul primului număr 999 = 1000
Al doilea este cu 1872 mai mare= 1872 + 1000 = 2872
Al treilea care sunt primele două împreună = 1000 + 2872 = 3872
∴
Suma celor trei numere = 1000 + 2872 + 3872
= 7744
