Answer:
Step-by-step explanation:
The sum of the angles in a triangle is always 180 degrees.
40+3x+180-5x+10=180
-2x+50=0
-2x=-50
x=25
Again using the fact that the angles must have a sum of 180
40+3x+a=180
40+3(25)+a=180
40+75+a=180
a+115=180
a=65
So angle 1 is 65 degrees.

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.
On Monday, Homeroom 104 turned in 64 canned goods. This is 17 less than the number of canned goods Homeroom 106 turned in.
Let c be the total number of canned goods in Homeroom 106. Then the equation is written as,
64 - c = 17
The equation that represents the total number of canned goods in Homeroom 106 on Monday will be 64 - c = 17. Then the correct option is B.

Answers
Answer:
The answer is 55 degrees.
Step-by-step explanation:
As shown by the red box on the angle, the angle shown is a right angle and is 90 degrees. Because we know the total angle measure, we can subtract the 31 degree angle from the 90 degree angle, which leaves us with 59 degrees for the second angle. This second angle equals (x+4). We then solve for x by setting up the equation 59= x+4. Subtract 4 from both sides and you are left with 55 degrees for x.

A bag holds 6 green, 9 red and 4 blue marbles a marble is selected at random what is the probability of not selecting a red marble?
Answers
Answer:
The probability of not selecting a red marble, P(R)' = 10/19
Step-by-step explanation:
The probability of an event occurring is equal to the number of ways the required event occurs divided by the number of possible outcomes
The number of ways of an event not occurring is 1 less the probability of the event occurring
The number of green marbles in the bag = 6
The number of red marbles in the bag = 9
The number of blue marbles in the bag = 4
The sum of the marbles in the bag, n = 6 + 9 + 4 = 19
The number of ways of selecting a red marble = 9 ways
The probability of selecting a red marble = 9 ways/19 marbles = 9/19
The probability of not selecting a red marble = 1 - 9/19 = 10/19 = [tex]0.\overline{526315789473684210}[/tex]
The probability of not selecting a red marble P(R)' = 10/19
Answer:
The probability of NOT selecting a red marble is 10/19 (or 52.6%)
Step-by-step explanation:
6 green+ 9 red+ 4 blue = 19 marbles in total. So 19 would be our denominator. The total of marbles that IS NOT red is 10 total (6+4). Now we would put 10 as our numerator. 10/19. We could simplify but 10 and 19 have no common factors. So it would but stay 10/19. Hope this helped

Write an exponential model given the points ( 7, 12 ) and ( 8, 25 ). Round to the nearest hundredth.
Answers
Answer:
The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
[tex]y = A\cdot e^{B\cdot x}[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]A, B[/tex] - Coefficients.
If we know that [tex](x_{1}, y_{1}) = (7,12)[/tex] and [tex](x_{2}, y_{2}) = (8,25)[/tex], then we get the following system of equations:
[tex]A\cdot e^{7\cdot B} = 12[/tex] (2)
[tex]A\cdot e^{8\cdot B} = 25[/tex] (3)
If we divide (3) by (2), we calculate the value of [tex]B[/tex]:
[tex]e^{B}=\frac{25}{12}[/tex]
[tex]B = \ln \frac{25}{12}[/tex]
[tex]B \approx 0.734[/tex]
And by (2), we determine the value of [tex]A[/tex]:
[tex]A = 12\cdot e^{-7\cdot B}[/tex]
[tex]A = 0.0704[/tex]
The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].
