Answers

Answer:

x = 54°.

Step-by-step explanation:

As we know, angles in a triangle add up to 180 degrees. a right angle is equal to 90 degrees so we know that the right angle is already 90 degrees. Now, we add the other angle we know, 36 degrees, to the 90°. this gives us 126 degrees. to work out angle x we need to 180 - 126. this will give you 54 degrees. We take the 126 degrees away to give us the remaining angle in the triangle.

Answer:

54 degrees

Step-by-step explanation:

If there are 180 degrees in a triangle and one of the points are 36 degrees then you need to figure out how much a right angle is... it is 90 degrees. 36 degrees + 90 degrees = 126 degrees. 180 degrees - 126 degrees = 54 degrees.

I NEED AN ANSWER ASAP AND PLS HURRY AND INCLUDE A STEP BY STEP EXPLANATION!!!!!

Answers

All triangles inner angles addition equals to 180°
So if you’re finding the x° then minus the other angles from 180°
23°+129°+x=180°
x=180°-129°-23°
x=28°
I hope this helped :)
X=28º
23+129=152

What is the equation of the line parallel to
3x + 2y = 8 and passes through the point
(4, -3)?

Answers

(4,-3)=1,x+y so easy broooooo

The equation of the line which is parallel to3x + 2y = 8 and passes through the point (4, -3) is y = -1.5x  + 3

How are parallel straight lines related?

Parallel lines have same slope, since slope is like measure of steepness and since parallel lines are of same steepness, thus, are of same slope.

How to get the slope intercept form of a straight line equation?

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

[tex]y = mx +c[/tex]

Let the straight line parallel to the line [tex]3x + 2y = 8[/tex] be [tex]y = mx +c[/tex]

Converting first line in slope intercept form, we get:

[tex]3x + 2y = 8\\\\y = -\dfrac{3x}{2} + 4\\\\y = -1.5x + 4[/tex]

Thus, the slope of the first line is -1.5

The second line being parallel to this, will have same slope. Thus, we get[tex]m = -1.5[/tex]

Thus, the equation of the second line is;

[tex]y = -1.5x +c[/tex]

Now, since it passes through (4,-3), therefore, putting x = 4 and y = -3 should satisfy the equation.

Thus, we get:

[tex]y = -1.5x +c\\\-3 = -1.5(4) + c\\c = 6-3 = 3[/tex]

Thus, the y-intercept of this line is c = 3

Thus, the equation of the second line is: y = -1.5x  + 3

Thus, the equation of the line which is parallel to3x + 2y = 8 and passes through the point (4, -3) is [tex]y = -1.5x + 3[/tex]

The graph of this equation is given below.

How do you find Median? I completely forgot

Answers

Answer:

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Step-by-step explanation:


To find the median, put all numbers into ascending order and work into the middle by crossing off numbers at each end. If there are a lot of items of data, add 1 to the number of items of data and then divide by 2 to find which item of data will be the median.

Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27.

f(x) = g(x - 3)(x - 5) for some g

f(x) = g(x^2 - 8x + 15)

Substitute (4, -1) for (x, f(x)) and solve for g.

-4 = g(4^2 - 8(4) + 15)

-4 = g(-1)

g = 4

The sales tax is $2.75, making the total cost $57.75.

Answer:

Step-by-step explanation:

The sales tax rate is 5%.  Writing that as a decimal, you have 5% = 0.05 (5 hundredths).

To find the amount of tax, multiply the price by 0.05.

0.05 x 55 = 2.75

The sales tax is $2.75.

The total cost of the shirt ("total" is a clue word) is the price + tax

$55.00 + $2.75 = $57.75

On Monday, a local hamburger shop sold a combined total of 408 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?

Answers

Answer:

I'm pretty sure the answer would be 102

Step-by-step explanation:

you divide 408 by 4 because the cheeseburgers sold 3x as much as the hamburgers.

102 hamburgers sold
306 cheeseburgers sold

h = hamburgers
c = cheeseburgers

c = 3h (number of cheeseburgers sold was three times the number of hamburgers sold)

c + h = 408

Substitute in the fact that c = 3h to the other equation:

3h + h = 408
4h = 408
h = 102

3h = 3(102) = 306

Check the math: 306 + 102 = 408
