The volume of a cube can be found using the equation v=s3 where v is the volume and a is the measure of one side of the cube
Answer:
s = ∛2560
Step-by-step explanation:
The volume of a cube is found by V = s³. To solve for the side of a cube with a specific volume, we use inverse operations to find it. s = ∛V. If the volume is 2560 then the s = ∛2560.

a number from 1 to 10 is chosen at random what is the probability of choosing a 4 or an odd number
Probably to get a 4 or 1,3,5,7,8 so is the probability of getting 1,3,4,5,7,8 so answer is 6/10=3/5
Answer:
6/10 or 0.6 or 60%
Step-by-step explanation:
The options for numbers are 1,2,3,4,5,6,7,8,9,and 10. There are 5 odd numbers from 1-10, 1,3,5,7, and 9. This woud be 50/50 odds. If you add four as an option, there would be 6 numbers, 1,3,4,5,7, and 9. the odds would be 6/10 which would be 60%.
Which statement is true?
-5.3 > 3.5
-2 4\9 > -2.6
- 7.09 < -7.10
-3.1 < - 11\3
The last one is the true statement
Correct option: 2. The only true statement is -2 4/9 > -2.6.
To determine which statement is true, let's compare the given pairs of numbers:
-5.3 > 3.5: This statement is false because -5.3 is less than 3.5.-2 4/9 > -2.6: Converting -2 4/9 to a decimal, we get -2.444. Since -2.444 is greater than -2.6, this statement is true.-7.09 < -7.10: This statement is false because -7.09 is greater than -7.10 (closer to zero on the number line).-3.1 < -11/3: Converting -11/3 to a decimal, we get approximately -3.6667. Since -3.1 is greater than -3.6667, this statement is false.The correct statement among the options is option 2. -2 4/9 > -2.6.
Complete Question:
Which statement is true?
-5.3 > 3.5-2 4\9 > -2.6- 7.09 < -7.10-3.1 < - 11\3Which of the following linear equations in standard form contains points (-2,4) and (3,9)?
Answer:
y=x+6
Step-by-step explanation:
If you need to find a standard linear equation from two points, you have to first find the slope, then find the y intercept.
To find the slope, you should do the change in y over the change in x.
that would be:
(4-9)/(-2-3)
(-5)/(-5)
the slope is 1
plug that in along with values of x and y taken from known point (3,9) to the standard equation of a linear relationship:
y=mx+b
m=1
y=9
x=3
b=?
9=(1)(3)+b
9=3+b
b=6
The equation of the line would be y=x+6
Answer:
x - y = - 6
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (3, 9)
m = [tex]\frac{9-4}{3+2}[/tex] = [tex]\frac{5}{5}[/tex] = 1, hence
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 9), then
9 = 3 + c ⇒ c = 9 - 3 = 6
y = x + 6 ← equation in slope- intercept form
Subtract y from both sides
0 = x - y + 6 ( subtract 6 from both sides )
- 6 = x - y, thus
x - y = - 6 ← in standard form
How many combinations of 4 students can a teacher choose from 30 students?
a. 27,405
b. 657,720
c. 120
d.810,000
Answer:
b. 27,405
Step-by-step explanation:
So, we have a total population of 30 (n) and we sample 4 (r) from it.
Now, is it a combination or a permutation? Does the order matter? Is it important that the teacher picked John before Andrew? No. So, it's a combination:
C(n,r)=C(30,4)
[tex]C(30,4) = \frac{30!}{4| (30-4)!} = 27405[/tex]
So, the teacher has 27,405 ways to combine groups of 4 students from his 30-student class.
Answer:
A

The low temperature in Chicago was -3 °F. The low temperature in Milwaukee was -11 °F. Which statement is true?
-11 is greater than -3, so it was colder in Chicago.
-3 is greater than -11, so it was colder in Chicago.
-11 is greater than -3, so it was colder in Milwaukee.
-3 is greater than -11, so it was colder in Milwaukee.
Answer:
The statement -11 is greater than -3, so it was colder in Milwaukee is true.
Answer:
-11 is greater than -3, so it was colder in Milwaukee.
Step-by-step explanation:
Answer 1 (-11 is greater than -3, so it was colder in Chicago) is incorrect because it was -3 in Chicago, not -11.
Answer 2 (-3 is greater than -11, so it was colder in Chicago) is incorrect because -3 is not greater than -11.
Answer 3 is correct because -11 is greater than -3 and the cities are labeled correctly.
Answer 4 (-3 is greater than -11, so it was colder in Milwaukee) is incorrect because -3 is not greater than -11. Milwaukee was also -11, not -3.

A fountain shoots a water arc that can be modeled by the graph of the equation y=-0.006x^2+1.2x+10, where x is the horizontal distance (in feet) from the river's north shore and y is the height (in feet) above the river. Does the water arc reach a height of 50 feet? If so, about how far from the north shore is the water arc 50 feet above the water?
ANSWER
The water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.
EXPLANATION
The water arc is modeled by the function:
[tex]y = - 0.006 {x}^{2} + 1.2x + 10[/tex]
We write this function in vertex form:
[tex]y = - 0.006 ({x}^{2} - 200x )+ 10[/tex]
[tex]y = - 0.006 ({x}^{2} - 200x + ( - 100)^{2} ) - - 0.006( - 100)^{2} + 10[/tex]
[tex]y = - 0.006 ( x- 100)^{2} ) + 60+ 10[/tex]
[tex]y = - 0.006 ( x- 100)^{2} ) +70[/tex]
The vertex of this function is at
(100,70).
This means that the water arc reached a height of 50ft.
We put y=50 and solve for x.
[tex]- 0.006 ( x- 100)^{2}+70 = 50[/tex]
[tex]- 0.006 ( x- 100)^{2} = - 20[/tex]
[tex]( x- 100)^{2} = \frac{10000}{3} [/tex]
[tex]x = 100 \pm \frac{100 \sqrt{3} }{3} [/tex]
x=42.3 or x=157.7
Hence the water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.
The water arc does reach a height of 50 feet, and it is about 42.27 feet and 157.73 feet from the north shore when it is 50 feet above the water.
1.Set up the equation:
[tex]\[ -0.006x^2 + 1.2x + 10 = 50 \][/tex]
2. Simplify the equation:
Subtract 50 from both sides:
[tex]\[ -0.006x^2 + 1.2x + 10 - 50 = 0 \] \[ -0.006x^2 + 1.2x - 40 = 0 \][/tex]
3. Solve the quadratic equation:
We can use the quadratic formula
[tex]\( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \), where \( a = -0.006 \), \( b = 1.2 \), and \( c = -40 \).[/tex]
[tex]\[ a = -0.006, \quad b = 1.2, \quad c = -40 \][/tex]
[tex]\[ \Delta = b^2 - 4ac \] \[ \Delta = 1.2^2 - 4(-0.006)(-40) \] \[ \Delta = 1.44 - 0.96 \] \[ \Delta = 0.48 \][/tex]
[tex]\[ x = \frac{-b \pm \sqrt{\Delta}}{2a} \] \[ x = \frac{-1.2 \pm \sqrt{0.48}}{2(-0.006)} \][/tex]
Calculate the square root of 0.48:
[tex]\[ \sqrt{0.48} \approx 0.6928 \][/tex]
Now, find the two values of x:
[tex]\[ x_1 = \frac{-1.2 + 0.6928}{-0.012} = \frac{-0.5072}{-0.012} \approx 42.27 \] \[ x_2 = \frac{-1.2 - 0.6928}{-0.012} = \frac{-1.8928}{-0.012} \approx 157.73 \][/tex]
Therefore, the water arc reaches a height of 50 feet at approximately [tex]\( x = 42.27 \) feet and \( x = 157.73 \)[/tex] feet from the north shore.
When the length of a rectangle with a width of 1/6 foot was increased by 2/3 foot, the area of the rectangle became 11/72 square feet. Find the original length of the rectangle. Explain your reasoning.
Answer:
1/4 is the original length
Step-by-step explanation:
The original length of the rectangle is 11/72 square feet. To get the area of a rectangle, you multiply the length x width.
You already know the width in this problem. The width is 1/6 feet. So, divide the area (11/72 feet) by the width (1/6 feet) to get the length, 11/12 feet.
However, the original length was increased by 2/3 feet. So, take our new length (11/12 feet) and subtract the increased length (2/3 feet) from it. When you do that, you get 1/4 feet.
Therefore, the answer is 1/4 feet. Hope this helps! :)

I need to find the measure of each angle indicated
1. From the given right-triangle, the side opposite to [tex]\theta[/tex] is 6.8 units.
The adjacent side to [tex]\theta[/tex] is 4 units.
Recall the mnemonics, SOH-CAH-TOA.
We use the tangent ratio to obtain:
[tex]\tan \theta=\frac{Opposite}{Adjacent}[/tex]
[tex]\tan \theta=\frac{4}{6.8}[/tex]
[tex]\tan \theta=\frac{10}{17}[/tex]
[tex]\implies \theta=\tan^{-1}(\frac{10}{17})[/tex]
[tex]\implies \theta=30.5\degree[/tex] to the nearest tenth.
2. This time we were given the hypotenuse to be 15.7 units and the adjacent side is 6 units.
We use the cosine ratio to obtain:
[tex]\cos \theta=\frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos \theta=\frac{6}{15.7}[/tex]
[tex]\cos \theta=\frac{60}{157}[/tex]
[tex]\implies \theta=\cos^{-1}(\frac{60}{157})[/tex]
[tex]\implies \theta=67.5\degree[/tex] to the nearest tenth.

26). 30.46°
Step-by-step explanation:
Points to remember
Trigonometric ratios
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
To find the answer of question 25
Cos θ = Adjacent side/Hypotenuse
= 9/15.7 = 0.573
θ = Cos⁻¹(0.573) = 55.02°
To find the answer of question 26
