x+3y=0 and 12y=-4 equation plz help.
Answer:
[tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]
Step-by-step explanation:
So we can equate the second equation in terms of y by dividing both sides by 12:
[tex]y = -\frac{1}{3}[/tex]
Let us substitute this into the first equation:
[tex]x + 3y = 0[/tex]
then becomes
[tex]x + 3(-\frac{1}{3} ) = 0[/tex]
which simplifies to
[tex]x - 1 = 0[/tex]
Finally solving for x gives us:
[tex]x = 1[/tex]
Therefore, [tex]x = 1[/tex] and [tex]y = -\frac{1}{3}[/tex]
Hope this helps!

help!!! it's a circumference problem!
Answer: 69.12
Step-by-step explanation: circumference=2*pi*radius
Answer:
The circumference of the circle is 69.12 m
Step-by-step explanation:
Circumference of a Circle
Given a circle of radius r, the circumference or perimeter of the circle is calculated by the formula:
[tex]C=2\pi\ r[/tex]
The circle shown in the image has a radius of r=11 m, thus the circumference is:
[tex]C=2\pi\ *11[/tex]
[tex]C=22\pi[/tex]
Calculating:
C = 69.12 m
A train left a station at 8:13 a.m. arriving at its destination at 4:52 p.m. If the stations are 527.65 miles apart, calculate the average
speed at which the train traveled.
A. 71 miles/hour
B. 69 miles/hour
C. 51 miles/hour
D. 61 miles/hour
9514 1404 393
Answer:
D. 61 mi/h
Step-by-step explanation:
The travel time is 16:52 -8:13 = 8:39 hours, or 8.65 hours. Then the speed is ...
speed = distance/time = 527.65 mi/(8.65 h) = 61 mi/h
_____
Additional comment
It is often convenient to use "military" or "24-hour" time for calculations of time periods that extend over noon or midnight. For this purpose, 12 gets added to the hour number in the afternoon (pm). Of course, 39 minutes is 39/60 hours. That is found to be 0.65 hours by performing the division of 39 by 60.

3 is not in the range.
What is the range?A function's range is the whole set of potential values that it can have. When we insert an x value into the function, the range is the collection of values that results. Range refers to the y values.
Given a figure in which the function is not differentiable since the graph is broken at (-2, 3) and (2, 4). Since at Y = 3 there is no point in the graph. therefore Y = 3 is not in the range of the function.

Answer:
AB = 17 m, AC ≈ 19.2 m
Step-by-step explanation:
Drawing a line from A to the base creates a right triangle
with legs 8 and (25 - 10 ) = 15
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² = 15² + 8² = 225 + 64 = 289 ( take the square root of both sides )
AB = [tex]\sqrt{289}[/tex] = 17 m
------------------------------------
Using Pythagoras' identity i right triangle ABC
AC² = AB² + BC² = 17² + 9² = 289 + 81 = 370 ( take square root of both sides )
AC = [tex]\sqrt{370}[/tex] ≈ 19.2 m ( to 1 dec. place )

During batting practice, Lenora hit 60% of the 20 pitches that were thrown to her. What fraction of the pitches thrown did Lenora hit?
Answer:
A 3/5
Step-by-step explanation:Here’s one way to solve this problem.
Write sixty percent as a fraction having a denominator of one hundred.
Now, change sixty-hundredths to an equivalent fraction having a denominator of twenty, the total number of pitches.
Do this by dividing the numerator and the denominator by five.
Then, simplify the fraction twelve-twentieths by dividing the numerator and the denominator by four.
So, Lenora hit three-fifths of the pitches.

and Sal is 175ft, what is the angle of Sonny's line of sight to both Sam and Sal to the
nearest whole degree?
a. 25°
b. 75°
c. 57°
d. 123°
Answer:
Step-by-step explanation:
Answer:
b. 75°
Step-by-step explanation:
Draw a triangle. Write a person name and a point name (a letter) at each vertex: Sam A, Sonny B, and Sal C at the vertices.
Write the distances as AB = c = 153 ft; AC = b = 201 ft; BC = a = 175 ft.
We are looking for angle B.
Since we have a triangle with three side lengths and no angle measures, we use the Law of Cosines.
[tex] b^2 = a^2 + c^2 - 2ac \cos B [/tex]
[tex] 201^2 = 175^2 + 153^2 - 2(175)(153) \cos B [/tex]
[tex] 40401 = 30635 + 23409 - 53550 \cos B [/tex]
[tex] -53550 \cos B = -13643 [/tex]
[tex] \cos B = \dfrac{-13643}{-53550} [/tex]
[tex] \cos B = 0.254771242 [/tex]
[tex] B = \cos^{-1} 0.254771242 [/tex]
