3. Ramona drank 1 5/8 liters of water during soccer practice. She drank 1 1/4
liters of water on the ride home. Which expression could be used to
determine the amount of water, in liters, Ramona drank altogether?
Answer:
The expression x = [tex]\frac{13}{8}+\frac{5}{4}[/tex] could be used to determine the amount of water drank altogether.
Step-by-step explanation:
Given that:
Amount of water drank during practice = [tex]1\frac{5}{8} = \frac{13}{8}[/tex] liters
Amount of water drank on the ride home = [tex]1\frac{1}{4} = \frac{5}{4}[/tex] liters
Let,
x be the total amount of water drank by Ramona.
x = Water drank during practice + Water drank on the ride home
x = [tex]\frac{13}{8}+\frac{5}{4}[/tex]
Hence,
The expression x = [tex]\frac{13}{8}+\frac{5}{4}[/tex] could be used to determine the amount of water drank altogether.

Stacia has 28 red and blue marbles. The ratio of red to blue marbles is 1:6. How many blue marbles does Stacia have?
Answer:
The total number of blue marbles = 24Step-by-step explanation:
Total number marbles Stacia has = 28
The ratio of red to blue marbles = 1 : 6
Let 'r' be the number of red marbles.Let 'b' be the number of blue linesAs the total number of marbles is 28. Thus,
r + b = 28
As the ratio of red to blue marbles is 1 to 6.
It means for each red marble 'r', we have 6 blue 'b' marbles. Thus,
b = 6r
now substituting b = 6r in the equation r + b = 28
r + b = 28
r + 6r = 28
7r = 28
divide both sides by 7
7r/7 = 28/7
r = 4
Thus,
The total number of red marbles ⇒ r = 4
The total number of blue marbles ⇒ b = 6r = 6(4) = 24
Therefore,
The total number of blue marbles = 24Find the unit rate.

|2n|-4=8 solve for n
Answer:
n = ± 6
Step-by-step explanation:
absolute value equations usually produce 2 solutions
to get the positive solution just solve normally: 2n - 4 = 8
2n = 12
n = 6
to get the negative solution you must take what is in the absolute value bars and multiply by negative one: -(2n) - 4 = 8
-2n - 4 = 8
-2n = 12
n = -6

A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9. Each character in the password cannot be used more than once.
What is the approximate probability that exactly one of the four characters will be a number?
1%
11%
28%
44%
The approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
A randomly generated password contains four characters. Each of the four characters is either a lowercase letter or a digit from 0–9.
Total letters = 26
Total numbers = 10
Total = 10 + 26 = 36
Total possibilities = 36×35×34×33 = 1413720
Password with one number = C(10, 1) = 10
With three letters = C(26, 3) = = 2600
Outcomes = 2600×10 = 26000
Favorable outcomes = 26000×4! = 624000
Probability = 624000/1413720 = 0.44 = 44%
Thus, the approximate probability that exactly one of the four characters will be a number is 44% option fourth is correct.

Write an equation for the line that passes through the points (0, -2) and (-4, 0).
y = - x - 4
y = -2 x - 4
y = -2 x - 2
y = - x - 2
Answer:
y=-1/2x-2
Step-by-step explanation:
I dont think any of those options are the right one so thats the correct answer
Answer: y = -1/2x - 2
Step-by-step explanation:
To first write the equation, we need to find the slope and the y intercept and write it in the form y=mx +b
To find the slope, we will find the difference between the y coordinates and divide it by the difference between the x coordinates.
The y coordinates of the points are , 0 and -2
The x coordinates of the points are -4 and 0
0 - (-2) = 2
-4 -0 = -4
Slope: 2/-4 = -1/2
Now using the formula y=mx+b, you will input the slope and use one of the given point's coordinates to solve for b the y intercept.
We will use the point (0,-2)
-2 = -1/2(0) + b
-2 = b
This means the equation will be y = -1/2x - 2
△XYZ is translated up 3 units to form the image ∆X′Y′Z′.
What are the coordinates of the vertices of ∆X′Y′Z′ ?
Enter your answer by filling in the boxes.
Answer:
The coordinates of the vertices of ∆X′Y′Z′:
X'(-4, 9)Y'(1, 9)Z'(1, 4)Step-by-step explanation:
Given the triangle △XYZ with the vertices
X(-4, 6)Y(1, 6)Z(1, 1)It is stated that △XYZ is translated up 3 units to form the image ∆X′Y′Z′.
Translating 3 units UP means we have to add 3 units to all the y-coordinates of the coordinates of the vertices X, Y, and Z to generate the image ∆X′Y′Z′.
Thus,
THE RULE OF TRANSLATING 3 UNITS UP:
P(x, y) → P'(x, y+3)
Therefore, the coordinates of the vertices of ∆X′Y′Z′ will be:
X(-4, 6) → X'(-4, 6+3) → X'(-4, 9)
Y(1, 6) → Y'(1, 6+3) → Y'(1, 9)
Z(1, 1) → Z'(1, 1+3) → Z'(1, 4)
Thus, the coordinates of the vertices of ∆X′Y′Z′:

Step-by-step explanation:
If a certain cannon is fired from a height of 9.8 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, in seconds, is found by the function h(t) = -4.9t² + 30.5t +9.8. Find the time it takes for the cannonball to strike the ground.
Answer:
6.53 s
Step-by-step explanation:
The height of the cannon ball is represented by a quadratic function as:
h(t) = -4.9t² + 30.5t +9.8.
At 0 s (i.e. t = 0), h(0) = -4.9(0²) + 30.5(0) + 9.8 = 9.8
That means that the cannon ball is initially at a height of 9.8 m above the ground. To calculate the time it takes the ball to touch the ground, we use:
h(t) = -4.9t² + 30.5t +9.8
It touches the ground when h(t) = 0. Hence:
0 = -4.9t² + 30.5t + 9.8
Solving the above quadratic equation gives:
t = 6.53 s and t = -0.31 s
Since the time cannot be negative, hence t = 6.53 s. Therefore it takes the ball 6.53 s to hit the ground.
Evaluate this expression.
