Answer:

33 braids

Step-by-step explanation:

What you want to do is first put in the equation. You put in 0.75x + 4=29.

Then you subtract 4 from 29 and get 25. Then divide 25 by 0.75 and you get the answer 33.3333333333. Round it to the nearest whole number and you get the final answer of 33 braids.

29 = 4 + .75b
subtract 4
25 = .75b
divide .75
b = 33.3333333
b = 33 braids

Does the ordered pair, (1, 5/2) satisfies the given equation<br> 3x-3y=-3 ?
vampirchik [111]

Answer:

Ordered pair, (1, 5/2) does not satisfy the given equation  3x-3y=-3

Step-by-step explanation:

3x-3y=-3

Here (x, y) = (1, \frac{5}{2} )

3(1)-3(\frac{5}{2} )=-3

3- (\frac{15}{2} )=-3\\6-15=-6\\-9\neq -6

If the average(arithmetic mean) of 5 and r is 7 and the average of 3 and s is 3 , what is the average of r and s?
Norma-Jean [14]

Answer:

C

Step-by-step explanation:

Calculate the values of both r and s, that is

\frac{5+r}{2} = 7 ( multiply both sides by 2 )

5 + r = 14 ( subtract 5 from both sides )

r = 9

and

\frac{3+s}{2} = 3 ( multiply both sides by 2 )

3 + s = 6 ( subtract 3 from both sides )

s = 3

Hence

\frac{9+3}{2} = \frac{12}{2} = 6 → C

Determine whether the function f(x) = 0.25 (2x - 15)^2 + 150 has a maximum or minimum.
AnnyKZ [126]

Answer:

minimum

Step-by-step explanation:

Given a quadratic function in vertex form

f(x) = a(x - h)² + k

• If a > 0 then f(x) is a minimum

• If a < 0 then f(x) is a maximum

f(x) = 0.25(2x - 15)² + 150 ← is in vertex form

with a = 0.25 > 0

Thus f(x) has a minimum turning point
