Mathematics
1 answer:
kiruha [24]3 years ago
3 0

Answer:

35% of the sixth grade is in the chess club

Step-by-step explanation:

if there are 100 students consider that as 100%

20 is a fifth of 100

20 x 5 =100

since 7/20 is a fraction you multiple the numerator (7) with the same number you multiplied to the denominator (20) which is 5.

7 x 5 = 35

35/100 = 35%

Which function has a vertex at (2, –9)?
Ivahew [28]
The solutions or roots so-called are really just the x-intercepts, and for a quadratic equation, the vertex is found right half-way between those x-intercepts.

we can get the intercepts by zeroing out "y" or f(x), so let's take a peek at one of those,

\bf \stackrel{f(x)}{0}=(x-5)(x+1)
\\\\\\
0=x-5\implies \boxed{5=x}\qquad \qquad \qquad \qquad 0=x+1\implies \boxed{-1=x}

so, the x-intercepts or solutions are at 5 and -1, let's take a peek what's the halfway point.

-1----0----1----  2  ----3-----4------5

well then, now we know the vertex is at x = 2, but, what's the y-coordinate of it anyway?

y = (x - 5)(x + 1)

y = (2 - 5)(2 + 1)

y = (-3)(3)

y = -9

Kazeer [188]

Answer:

There are 10 orange marbles

Step-by-step explanation:

There are 25 marbles in the bag

40% are orange

To determine the number of orange marbles, we multiply the total number of marbles  by the percent that are orange

25 *40% = number of orange marbles

25*.40

10

There are 10 orange marbles
