Answer:

8 with 1/2 a pizza left

Step-by-step explanation:

first you divide 30 by 4 which will get you about 7 but there will be 2 students left so you order 8 and take away 2/4 of the last pizza which leaves 1/2 of a pizza left

What is the measure of def 78° PLEASE HELP
Scorpion4ik [409]

Answer:

The measure of arc DEF is 204°

B is correct

Step-by-step explanation:

In a circle center at O.

∠DOF and ∠DEF are lie on same base but ∠DOF at center and ∠DEF on circle.

Thus, ∠DOF = 2 ∠DEF

minor ∠DOF = 2 x 78 = 156°

We need to find arc DEF.

DEF is central angle of major∠DOF

major∠DOF + minor ∠DOF = 360°     (Complete angle at center)

            major∠DOF  +  156° = 360°

                         major∠DOF = 204°

major∠DOF is arc DEF.

Hence, The measure of arc DEF is 204°

What is the equation, in slope-intercept form, for the line that passes through the point (2, −3) and is perpendicular to the li
diamong [38]

Answer:

The equation is;

y = (-x-23)/25

Step-by-step explanation:

The equation of a straight line can be given as y = mx + b

where m is the slope and b is the y-intercept

for y = 25x + 4

m is 25

Now, we need the slope of a line perpendicular to this,

If two lines are perpendicular, the result of the product of their slopes is -1

m1 * m2 = -1

25 * m2 = -1

m2 = -1/25

Mathematically, we have the slope in the point slope form as ;

y+3 = -1/25 (x - 2)

y = -x/25 + 2/25

y = -x/25 + 2/25 - 3

y = -x/25 -73/25
