Answer:
x = 140 degrees
Step-by-step explanation:
this polygon has 6 sides
to find the number of degrees of the six interior angles you can use this formula:
(n-2)*180 where 'n' equals the number of sides
(6-2)*180 = 4(180) = 720 degrees
starting with the 'x' angle and going clockwise, we have the following:
x + 90 + 104 + 123 + 155 + 108 = 720
x + 580 = 720
x = 720 - 580
x = 140
Write 7.67 times 10 -² in standard notation.
7.67 times 10^-² in standard notation can be written as 0.0767.
To convert scientific notation to standard notation, you can simply move the decimal point to the left or right as many times as indicated by the exponent of the power of 10. In this case, the exponent is -2, so you move the decimal point 2 places to the left. The result is 0.0767.
Use your formula 1/2(a+b)h, to determine the height of a trapezoid with an area of 24 cubic centimeters and base lengths of 9 cm and 7 cm.
The height of the trapezoid with an area of 24cm² and base lengths of 9 cm and 7 cm is 3cm.
What is the height of the trapezoid?A trapezoid is simply a quadrilateral with at least one pair of parallel sides.
The area of a trapezoid is expressed as;
A = 1/2(a+b)h
Given that;
Area A = 24 cmBase side a = 9cmBase side b = 7cmHeight h = ?Plug in the values into the above formula and solve for h.
A = 1/2(a+b)h
A = 1/2(a+b)h
2A = (a+b)h
2A/(a+b) = h
h = 2A/(a+b)
h = ( 2 × 24cm² ) / ( 9cm + 7cm )
h = 48cm² / 16cm
h = 3cm
Therefore, the value of height h is 3cm.

A radar gun meaured the peed of a baeball at 5 mile per hour. If the baeball wa going 4.2 mile per hour, what wa the percent error in thi meaurement?
The percent error in this measurement would be 16%.
1. Calculate the difference between the measured speed and the actual speed: 5 mph - 4.2 mph = 0.8 mph
2. Calculate the percent error: (0.8 mph / 4.2 mph) x 100 = 19.05%
3. Round to the nearest whole number: 19.05% = 19%
The percent error in this measurement is 19%, which means that the measured speed was 19% higher than the actual speed.
This can be caused by a variety of factors, including the radar gun being set to an incorrect sensitivity, the speed of the ball being too high for the radar gun to accurately measure, or the radar gun not being able to accurately detect the speed of the ball due to environmental factors such as wind or lighting.

Line a which passes (1, 4) has a constant of proportionality of 4.
Line b runs through (5, 2), with a constant of proportionality of 2/5.
What is the Constant of Proportionality?The constant of proportionality is often represented by the letter "k" and it is used in a mathematical relationship known as a proportionality relationship. The proportionality relationship can be written as y = kx, where y and x are the two variables and k is the constant of proportionality.
This means that the value of y is directly proportional to the value of x and is equal to k times the value of x. The value of k can be found by dividing the value of y by the value of x, when the two variables are in proportion.
Line a passes through the (1, 4), therefore:
constant of proportionality = y/x = 4/1 = 4.
Line b passes through the (5, 2), therefore:
constant of proportionality = y/x = 2/5.

A confounding variable is an extraneous factor that can influence the results of a study. In this case, the medical study reported that people who owned pets had lower blood pressure than those who did not own pets. This led some doctors to believe that pet ownership had positive health benefits. However, further analysis of the data revealed that the pet owners in the study also exercised more and smoked less than those who did not own pets.

Yusuf drove 156 miles in 3 hours. If he continued at the same rate, how far would he travel in 2 hours?
The distance travelled by Yusuf in 2 hours is 104 miles.
What is the distance travelled by Yusuf?Speed is simply referred to as distance traveled per unit time.
Mathematically, Speed = Distance ÷ time.
Given that, Yusuf drove 156 miles in 3 hours.
We determine the speed of Yusuf.
Speed = Distance / time
Speed = 156 miles / 3 hours
Speed = 52 miles per hour
Now, the distance travelled in 2 hours will be;
Speed = Distance / time
Distance = Speed × time
Distance = 52 miles per hour × 2 hours
Distance = 104 miles.

How to find proportional parts in triangles and parallel lines?
If a line parallel to one side of a triangle contacts the other two sides of the triangle, the line proportionally splits these two sides. If DE = BC, then ADDB=AEEC.
If a line parallel to one side of a triangle contacts the other two sides, the two sides are proportionately divided.
The formula for a proportional equation is y = kx. The letters y and x denote the variables in the equation. The letter k represents the proportionality constant, which is fixed.
Because matching angles produce the AA similarity shortcut, when a line is drawn parallel to one side of a triangle, two similar triangles are generated. Because the triangles are comparable, the parallel line segments are proportionate segments.

at Freddy's, three steak burgers zzz and two orders of fries cost $18. Two steak burgers and three orders of fries cost $15.75. What is the cost for one steak burger? What is the cost of one order of feries
The cost of one steak burger is $4.5 and the cost of one order of fries is $2.25.
How to find a cost using equation?To find a cost using an equation, you need to first identify the variables involved in the equation.
Variables are values that can change, such as the price of an item or the quantity of an item. Next, you must determine the value of each variable.
Once you have all the values, plug them into the equation and solve for the cost. For example, if you have an equation where x is the cost, y is the quantity, and z is the price per item, you would plug in the values of y and z and solve for x.
The answer you get would be the cost of the item. Additionally, you can use the equation to find the cost of multiple items by changing the value of the variable y to represent the amount of items you need.
After plugging in the new values into the equation, you can solve for the cost of all the items.
Let x be the fries and y be the steak burgers.
From the following information, the equation are as follows:
2x + 3y = 18 ---------equation 1
3x + 2y = 15.75 -------equation 2
To find cost of one steak burger and cost of one order of fries,
Multiply by 3 in equation 1 and 2 in equation 2,
6x + 9y = 54 -------3
6x + 4y = 31.5 -----4
Subtracting the equation 3 and 4, we get
5y = 22.5
y = 22.5/5
y = 4.5
Substitute y=4.5 in eq 1,
2x + 3(4.5) = 18
2x = 4.5
x = 2.25
∴ The cost of one steak burger is $4.5
∴The cost of one order of fries is $2.25.

The probability that the artist chosen will be a painter or a photographer is 3/4
What is probability?Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.
To solve this exercise the formula and the procedure that we have to use for probability is:
probability= (achieving success / possible outcomes)
Achieving success = 7 painters + 5 photographer = 12
Possible outcomes = 7 painters + 5 photographer + 4 sculptors = 16
Applying the formula to calculate the probability we get:
probability= (achieving success / possible outcomes)
probability= 12/16
