Answer:
x = 10
y = 20
Step-by-step explanation:
7x + 90 + 20 = 180
7x = 70
x = 10
5x + 2y = 90
50 + 2y = 90
2y = 40
y = 20

If the domain of f(n) = -4n - 3 is (-1, 1/4,4}, what is the range?
O(-1, 2, -19)
O(-7,-4, -13)
O {1,-4, -19)
Answer:
[tex]Range= \{1,-4,-19\}[/tex]
Step-by-step explanation:
Given
[tex]f(n) = -4n - 3[/tex]
[tex]n = \{-1,1/4,4\}[/tex] --- domain
Required
Determine the range
To do this, we simply substitute the values of n in the given expression
So, we have:
[tex]n = -1[/tex]
[tex]f(-1) = -4 * -1 - 3 =4 - 3 = 1[/tex]
[tex]n = 1/4[/tex]
[tex]f(-1) = -4 * 1/4 - 3 =-1 - 3 = -4[/tex]
[tex]n=4[/tex]
[tex]f(-1) = -4 * 4 - 3 =-16 - 3 = -19[/tex]
Hence, the range is:
[tex]Range= \{1,-4,-19\}[/tex]

If the surface area of a cube is 150 cm2, what is the volume of the cube
Answer:
V = 125 in^3
Step-by-step explanation:
A cube has 6 sides, and the area of each is equal to the side length squared:
A = 6x^2
A is given as 150 cm^2, and so is equal to 6x^2. Thus, x = the side length = 5 cm.
The volume of the same cube is given by V = x^3, which here is 5^3 in^3, or V = 125 in^3

Please tell me if what I did is correct, and if it's wrong can you help me?
Answer:
This answer is correct I got it right on khan.
Step-by-step explanation:
We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.
The given vertices are (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5).
We need to plot the given vertices on the graph.
How to plot the given points on the graph?A point in a plane contains two components where order matters! It comes in the form (x, y) where x comes first, and y comes second.
The x-value tells how the point moves either to the right or left along the x-axis. This axis is the main horizontal line of the rectangular axis or Cartesian plane.The y-value tells how the point moves either up or down along the y-axis. This axis is the main vertical line of the rectangular axis or Cartesian plane.We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.

A cylindrical jar of jam has a diameter of 6cm and a height of 8cm if the jar is 70% full how many cubic centimeters of jam is in the jar?
Answer:
[tex] 158.256 \: {cm}^{3} [/tex]
Step-by-step explanation:
For cylindrical jar:
Diameter = 6 cm
Radius (r) = 6/2 = 3 cm
Height (h) = 8 cm
[tex]V_{cylindrical \: jar} = \pi {r}^{2} h \\ \\ = 3.14 \times {(3)}^{2} \times 8 \\ \\ = 3.14 \times 72 \\ \\ = 226.08 \: {cm}^{3} \\ \\ \because \: jar \: is \: filled \: upto \: 70 \% \\ \\ \therefore \: V_{jam} = 70 \% \: of \: V_{cylindrical \: jar} \\ \\ \therefore V_{jam} = 0.70 \times 226.08 \\ \\ \therefore V_{jam} = 158.256 \: {cm}^{3} [/tex]

3 rational number between -3/2 and 0
Answer: 'So, the 3 rational numbers between 0 and 1 are 21,41 and 43.Jan 11, 2021'
Step-by-step explanation:
If the 12-sided solid is rolled 180 times, how many times would you expect either number a 3, 9 or 11 to be rolled?
The probability that the 12-sided solid gets 3 , 9 or 11 is P ( A ) = 1/4 and the expected number of times is n = 45
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability that the the 12-sided solid gets 3 , 9 or 11 be P ( A )
Now , the value of P ( A ) is
Let the number of outcomes when rolling a 12-sided solid = 12
The number of times the solid is rolled = 180 times
So , the total number of outcomes = 12 x 180 = 2160
And , the probability of getting a 3 = 1/12
The probability of getting a 9 = 1/12
The probability of getting a 11 = 1/12
So , the total probability of getting a 3 , 9 or 11 = 3/12 = 1/4
The total expected number of times = 45
Hence , the probability is 1/6
