The volume of this rectangular prism is 80 cm (small number 3) Use the volume formula to determine the height of this prism.
Answer:
Finding the volume of a rectangular prism is a straightforward task - all you need to do is to multiply the length, width, and height together: Rectangular prism volume = length * width * height. Where can you use this formula in real life? Let's imagine three possible scenarios: You bought a fish tank for your golden fish . It's in a regular box shape, nothing fancy, like a corner bow-front aquarium. If …

how to solve x-3=2-3x
Answer:
x = 5/4
Step-by-step explanation:
x-3=2-3x
Add 3x to each side
x+3x-3=2-3x+3x
4x-3 = 2
Add 3 to each side
4x-3+3 = 2+3
4x =5
Divide each side by 4
4x/4 = 5/4
x = 5/4
Answer:
5/4
Step-by-step explanation:
[tex]x-3=2-3x\\-3=2-4x\\-5=-4x\\\frac{-5}{-4} =x\\x=\frac{5}{4}[/tex]
Combine all like terms by moving them to their respective sides, then simplify as best you can.

A cyclist travels 5.3 km in 30 minutes. What is his average speed in km/h?
Answer:
10.6 km/h
Step-by-step explanation:
avg. speed in km/h literally tells us how much distance (in km) the cyclist travels in an hour. An hour happens to be double that of 30 minutes, so the distance will be double of 5.3km. The distance over an hour is 10.6km, so the speed is 10.6km/h.
Alternatively, you can simply divide distance by time:
5.3km / 30min = 5.3km / (1h / 2) = 5.3km * 2 / 1h = 10.6km/h
Answer:
hope this helps
Step-by-step explanation:
5.3 km 3.293 miles so the average speed would be 6.59 mph

Answer:
41. - 0.8
42. - 2.375
43. - 0.625
44. - 0.833
45. - 3.667
46. - 0.5
Step-by-step explanation:
Before reading this, every integer represents the whole amount, like 1 is 1 of something, 2 is 2 of something, 3 is 3 of something, and 4 is 4 of something.
1/5 = 0.2
1 - 0.2 = 0.8
1/4 = 0.25
1/8 = 0.125
1 + 1 = 2
0.25 + 0.125 = 0.375
2 + 0.375 = 2.375
3/8 = 0.375
1 - 0.375 = 0.625
2/3 = 0.667
1/2 = 0.5
4.5 - 3.667 = 0.833
1/2 = 0.5
1/6 = 0.167
2 + 1 = 3
0.5 + 0.167 = 0.667
3 + 0.667 = 3.667
1/4 = 0.25
0.25 x 2 = 0.5

During second period, Bonnie completed a grammar worksheet. She got 18 out of 20 questions correct. What percentage did Bonnie get correct?
Answer:
90% correct
Step-by-step explanation:
You want to make calculating easy and to do this, you multiply write out 18 out of 20 like a fraction, 18/20, and multiply both the numerator and the denominator by 5 because 20*5 = 100. 18*5 = 90. 90/100 is the same thing as 90%. Hope this helps!

Answer:
x = 32
Step-by-step explanation:
3x -4 + 3x -8 = 6x -12
6x-12 = 180
in an equation, you do the same to both expressions
6x -12 +12 = 6x. 180+12 = 192
6x / 6 = x. 192 / 6 = 32
x = 32
What is the first time after midnight that all the digits on the display of a digital clock are prime numbers?
What is the value of the discriminant, b2
about the number of real solutions the equation has?
4ac, for the quadratic equation 0 x^2 - 4x + 5, and what does it mean
about the number of real solutions the equation has ?
The discriminant is -4 , so the 2 equation has 2 real solutions.
The discriminant is -4, so the equation has no real solutions.
The discriminant is 35, so the 2 equation has 2 real solutions
The discriminant is 35 , so the equation has no real solutions.
Answer: Choice B
Discriminant = -4; no real solutions
===========================================================
Explanation:
The given quadratic is x^2-4x+5, which is the same as 1x^2-4x+5
We see that
a = 1
b = -4
c = 5
The discriminant is
d = b^2 - 4ac
d = (-4)^2 - 4(1)(5)
d = 16 - 20
d = -4
The discriminant is -4. The negative discriminant means that we have no real solutions. Instead, the two solutions are nonreal complex values in the form [tex]a+bi[/tex] where [tex]i = \sqrt{-1}[/tex]
Answer:
The discriminant is -4, so the equation has no real solutions.
Step-by-step explanation:
The discriminant of the quadratic polynomial [tex]ax^2 + bx + c[/tex] with [tex]a\not= 0[/tex] is:
[tex]\Delta = b^2 -4ac[/tex]
So our variables are:
[tex]a = 1[/tex]
[tex]b = -4[/tex]
[tex]c = 5[/tex]
Replacing in the formula for find the discriminant we have:
[tex]4^2 - 4(1)(5) = 16 -20 = -4[/tex]
Now if you remember the quadratic formula is the next
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
The discriminant appear inside a square root that's meaning that is impossible have negative values inside an even root (in the real numbers).
If we try to find the square root of negative 4 that's meaning find a number that multiply by itself give me -4.
[tex]2 \cdot 2 = 4\\-2 \cdot -2 = 4[/tex]
How you can see is impossible get the solution of a negative base (the base is the number inside the root) when is an even root. In a general case this would be of the next form:
[tex]\sqrt[2n]{-a} = \text{not found}[/tex]
For this we can assure that doesn't exist solutions in the real numbers, so the equation has no real solutions.

From the table of values, it is clear that Alana chose the points (2,4) and (6,6). She also used this formula to find the slope:⤵⤵⤵
(sorry if it's a bit small btw)
[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]
She plugged in her values like so:
[tex] \frac{6 - 2}{6 - 4} [/tex]
But, right away we can tell that she put the values in the wrong places, because the y-values are supposed to be on top while the x-values are supposed to be on the bottom. Yet in this case, you can see that the 2 is an x-value, meaning she put it on the top, and thus the slope is wrong.
The correct way would be if she switched them around, where the y-values are on top and the x-values are on the bottom. With this in mind, the slope would actually be 2/4 which if you simplify it, it would be 1/2.
This is essentially your answer, feel free to use some of my words, if need.
Hope this helps :)

What is the equation of the line graphed below? Write your answer in slope-intercept form. (y = mx + b)
Don't forget to simply if you can!
Answer:
y = 2x + 2
Step-by-step explanation:
Slope = (change in y-values)/(change in x-values)
Slope = (-6 - 6)/(-4 - 2)
Slope = -12/-6
Slope = 2
Use the slope = 2 and point (2, 6) and substitute into y = mx + b to solve for b.
y = mx + b
6 = 2(2) + b
6 = 4 + b
b = 2
The equation is y = 2x + 2

f(x) = x^2 - 13x + 30
Step-by-step explanation:
A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).
f(x) = (x-3)(x-10)
f(x) = x^2 - 13x + 30

The amount of time operators of a popular amusement park ride spend loading, safety checking, and unloading guests is 5 minutes per ride. The operators also spend 200 minutes each day completing other ride-related and guest-service tasks while the ride cars are in the station. The ride itself takes 3 minutes to complete. If the amusement park is open on Saturdays for 12 hours (720 minutes), write an inequality to describe how many cycles of the ride, at most, can be completed on a Saturday.

Answer:
200 + 3x + 5x ≤ 720
(or simplified, 200 + 8x ≤ 720)
and x = 65
Step-by-step explanation:
x represents the number of rides
3 + 5 = 8
720-200 = 520
520/8 = 65
The inequality for the number of rides will be 200 + 3x + 5x ≤ 720. The number of rides will be 65.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality showed greater than and less than the relationship between variables and the numbers.
Given that the number of time operators of a popular amusement park ride spends loading, safety checking, and unloading guests is 5 minutes per ride. The operators also spend 200 minutes each day completing other ride-related and guest-service tasks while the ride cars are in the station. The ride itself takes 3 minutes to complete. If the amusement park is open on Saturdays for 12 hours (720 minutes),
The inequality will be written as below,
200 + 3x + 5x ≤ 720
Here, x represents the number of rides
3 + 5 = 8
720-200 = 520
520/8 = 65
Therefore, the inequality for the number of rides will be 200 + 3x + 5x ≤ 720. The number of rides will be 65.
