Answer: x=2.5

Step-by-step explanation:

First we need to set up and equation

10= 60 - 20x

where x is the amount the cookies cost

subtract 60 from both sides

-50=- 20x

now divide each side by 20 so hat we can isolate the x

-50/-20= x

x= 2.5

now to check just multiply it by 20 then subtract from 60.

2.5 x 10= 50

60-50=10

Kathy dropped a snowball from a building that is 39.2 meters tall. The equation t2 = 39.29.8 represents the amount of time, in s

DIA [1.3K]

Answer:

We note that the equation that is compatible with the given equation is the kinematic equation of free fall where;

t² = 39.2 × 2/9.81

From which we have;

The time it takes the snowball to reach the ground is approximately 2.83 seconds

Step-by-step explanation:

The height of the building from which the ball is dropped, h = 39.2 m

The equation of the dropped a snowball, is given as follows;

t² = 39.2 × 9.8

Using the From the equation of free fall, we have;

s = u·t + 1/2·g·t²

Where;

u = The initial velocity = 0 m/s

t = The time of flight

g = The acceleration due to gravity = 9.81 m/s²

Therefore, we get;

∴ s = The height from which the snowball is dropped = 39.2 m

Therefore, we get;

39.2 = 0×t + 1/2×9.81×t²

∴ t² = 39.2 × 2/9.81 ≈ 7.99

t = √(7.99) ≈ 2.83

The time it takes the snowball to reach the ground, t ≈ 2.83 s.

After reading a book foe English class, 100 students were asked whether or not they enjoyed it. Nine twenty-fifths of the class

Katena32 [7]

Answer:

The number of students who liked the book was 64.

Step-by-step explanation:

After reading a book for English class, 100 students were asked whether or not they enjoyed it.

Now, given that nine twenty-fifths of the class did not like the book.

So, $\frac{9}{25}$ of the whole class did not like the book.

Then, the fraction of the class who did like the book was $(1 - \frac{9}{25}) = \frac{16}{25}$ .

Therefore, the number of students who liked the book was $(100 \times \frac{16}{25}) = 64$ . (Answer)

Please help emergency

Firdavs [7]

Step-by-step explanation:

This is a probability related problem.

Probability is the likelihood of an event to occur;

Pr = $\frac{number of possible outcomes}{Total sample space}$

The sample space here is from 1 to 25 which is 25

Pr of a card marked 8; we have just 1 possible outcome;

Pr(8) = $\frac{1}{25}$

Pr of drawing a card that is a multiple of 5;

Multiples of 5 = 5, 10, 15 and 25

Pr (multiples of 5) = $\frac{4}{25}$

Pr of drawing a card with odd numbers:

Number of odd numbers between 1 and 25 = 13

Pr(odd numbers) = $\frac{13}{25}$

Pr of drawing a number with square number on it;

Square numbers between 1 and 25 = 1, 4, 9, 16 and 25

Pr(square numbers) = $\frac{5}{25}$ = $\frac{1}{5}$
