NikAS [45]3 years ago

Answer:

  7 people

Step-by-step explanation:

  (21 cookies)/(3 cookies/person) = 7 person

_____

If you're really challenged figuring this out, you can count out 21 of some object—such as pennies, scraps of paper, or even cookies—and deal them into piles of 3 each. Then count the piles. Working with actual physical objects can often give you mathematical insight not obtainable any other way.

Each pile subtracts 3 from the original amount. We use the arithmetic operation "division" to simplify repeated subtraction.

Knowing number facts such as 3×7 = 21 is very helpful to solving problems of this nature.

Serggg [28]

Answer:

502 m²

Step-by-step explanation:

We require to find b before calculating the surface area.

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth and h is height )

Here V = 510, l = b, b = 10 and h = 3, thus

b × 10 × 3 = 510

30b = 510 ( divide both sides by 30 )

b = 17

--------------------------

The opposite faces of a cuboid are congruent, thus

top/bottom area = 2(17 × 10) = 2 × 170 = 340 m²

front/back area = 2(17 × 3) = 2 × 51 = 102 m²

sides area = 2(10 × 3) = 2 × 30 = 60 m²

Surface area = 340 + 102 + 60 = 502 m²

How could you use coordinate geometry to prove that segment BD and segment AC bisect one another?
____ [38]

Answer:

I think it's prove the midpoints are the same

Step-by-step explanation:

I'm not completely sure but I'm taking it right now and I believe that's the most logical answer because if they meet up at the same midpoint then they could bisect each other.

A linear function has an x-intercept of 12 and a slope of 3/8. How does this function compare to the linear function that is rep
aivan3 [116]
We rewrite the statement correctly:
 "A linear function has an y-intercept of 12 and a slope of 3/8"
 Therefore, the linear function is:
 y = (3/8) x + 12
 We look for the linear function of the table:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)
 m = ((- 3/8) - (- 3/4)) / ((1/3) - (- 2/3))
 m = ((- 3/8) - (- 6/8)) / (3/3)
 m = ((- 3 + 6) / 8) / (1)
 m = 3/8
 (xo, yo) = (- 2/3, -3/4)
 Substituting:
 y + 3/4 = (3/8) (x + 2/3)
 y = (3/8) x + 2/8 - 3/4
 y = (3/8) x + 1/4 - 3/4
 y = (3/8) x + -2/4
 y = (3/8) x + -1/2
 The lines are:
 y = (3/8) x + 12
 y = (3/8) x + -1/2
 Answer:
 
It has the same slope and a different y-intercept
