Answer:

at least 20 rows.

Step-by-step explanation:

when you add the students, teachers, and chaperones, it comes to 159. then you divide 159 by the number of seats each row has, so 159/8 = 19.875, you would have to round to the nearest whole number so 20 should be correct.

10a. The y-intercept of the estimated line of best fit is at (0,b). Enter the approximate value of b. Round your estimate to the
vredina [299]

Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given as:

y = mx + b; where m is the slope of the line and b is the y intercept (that is value of y at x = 0).

a) From the graph, we can see that the straight line touches the y axis at $100 in which the temperature is 0 degrees. Therefore the y intercept is:

(0, 100)

b) The slope of the line can be gotten by taking two points that the line passes through. Using the points (0, 100) and (12, 500):

slope(m)=\frac{y_2-y_1}{x_2-x_1} =\frac{500-100}{12-0} =33.3

What else would need to be congruent to show that ABC =XYZ by SAS?<br> Given:<br> AB=XY<br> A=X
Sati [7]

ABC = XYZ  by  SAS

AB = XY    -     Side

A = X         -    Angle

So you want to find another congruent <em>side</em>.

Removing the taken possible side, two sides can be congruent.

Either :

BC = YZ

<em>OR</em>

AC = XZ

18 - (8 - 3 • (2t + 5)) = 0



6t + 25 = 0



3.1 Solve : 6t+25 = 0

Subtract 25 from both sides of the equation :
6t = -25
Divide both sides of the equation by 6:
t = -25/6 = -4.167

Final answer is

t = -25/6 = -4.167

M x+ B = y solve for B <br><br><br> A x+ B y = C solve for x <br><br><br> Bh/2 = A, solve for h
quester [9]

Step-by-step explanation:

Mx+B=y

B=y-Mx

Ax+By=C

Ax=C-By

Ax/A=C-By/A

x=C-By/A

Bh/2=A

2 x Bh/2=A x 2

Bh=2A

Bh/B=2A/B

h=2A/B
