What is the value of x?


degrees

Answers

Answer:

x = 48 degrees

Step-by-step explanation:

Every triangle has an interior angle of 180 degrees

to find x, take the known angles and add them together:

47 + 85 = 132

now take the sum and subtract it from 180;

180 - 132 = 48

x = 48 degrees

what is the linear equation of a line with a rate of change of -1/2 that passes through the point (0, 4)

Answers

Answer:

y = 9/2 (fraction)

Step-by-step explanation:

y = mx+c

m = slope

c =y -intercept

Therefore, the required equation is:

y = 2x + c

Putting the point (0,4) in it as it lies on a line, we get:

4 = -1/2 + c

Therefore:

c = 9/2

So, y = 9/2

B. x= 0.27
C. x = 3.71
D. x = 2.09

Answers

Answer:

C. x = 3.71

Step-by-step explanation:

4 + 9(ln x) = 15.8

Subtract 4 from both sides.

9(ln x) = 11.8

Divide both sides by 9.

ln x = 11.8/9

x = e^(11.8/9)

x = 3.71

4 + 9 • In x = 15.8

x= 3.71

Answer:

128°52°47°133°81°

Step-by-step explanation:

Alternate interior angles are congruent, so you know ...

  ∠2 = 52°

  ∠3 = 47°

The sum of angles in a triangle is 180°, so ...

  ∠5 = 180° -∠2 -∠3 = 180° -52° -47°

  ∠5 = 81°

Linear pairs are supplementary, so ...

  ∠1 = 180° -∠2 = 180° -52°

  ∠1 = 128°

  ∠4 = 180° -∠3 = 180° -47°

  ∠4 = 133°

_____

Alternate solution

To find angles 1 and 4, you could also make use of the fact that same-side interior angles are supplementary.

Find an equation of the line parallel to y = 3x + 2 and that passes through the point (-1, -3)

Answers

In order to be parallel to a line, two lines must have the same slope. The slope of y=3x+2 is 3. So the slope of the other equation has the be 3. y=3x+b. Now we can plug in the x and y values given by the point to calculate the b in the equation.
-3=3(-1)+b
-3=-3+b
b=0
So the equation is y=3x

L = length

length x width x height

length = 5 in

width = 2 in

height = 10 in

2(10 * 2) + 2(10 * 5) + 2(2 * 5)

12x - 100 < 500
12x + 100 < 500

Answers

Answer:

Each student club must contribute $ 33.33 in order to meet the fundraising goal.

Step-by-step explanation:

Given that a school fundraiser has a minimum target of $ 500. Faculty have donated $ 100 and there are 12 student clubs that are participating with different activities, to determine how much money should each club raise to meet the fundraising goal, the following calculation must be performed:

(500 - 100) / 12 = X

400/12 = X

33,333 = X

Thus, each student club must contribute $ 33.33 in order to meet the fundraising goal.
