Answer:

Eleana is 20 years old and her grandfather is 80 years old.

Step-by-step explanation:

So first off, we want to make variables to represent Eleana and her grandfather.

Let x represent Eleana's age.

Since her grandfather is four times older than Eleana,

The expression should be 4x+x=100

Step One

Add the x's together and you get 5x=100.

Step Two

Divide both numbers by 5 to solve for x.

x=20

Answer:

false

Step-by-step explanation:

it fails the vertical line test, (x cannot be equal to 2 or more y values or its not a function)

To check if a graph is a function, we use the vertical line test. If your run a vertical line over the function, are there any places where the line intersects the graph more than once? If so, it's not a function.

In this case, if we have a line at x = 0, the line will go through more than one point - (0, 0) and (0, 3.1) [exact value doesn't matter, what matters is that there's a point there]. That means that this is not a function, so the statement is false.

Answer:

D. two real solutions

Step-by-step explanation:

p²+5 = 6p

p² - 6p +5 =0

D = b² - 4ac = (-6)² - 4*(1)*5 = 36 - 20 = 16

D > 0, so this equation has 2 real solutions

Answer:

12762.72 cubic meters

Step-by-step explanation:

The volume of a cylinder is denoted by the formula: [tex]V=\pi r^{2} h[/tex], where r is the radius and h is the height.

Here, we see that the height h = 11.5 m. We also see that the diameter is 37.6 meters. Since diameter = 2 * radius, we can divide this number by 2 to get the radius: r = 37.6/2 = 18.8 meters.

Now substitute these values into the equation:

[tex]V=\pi *(18.8^2)*11.5=3.14*(18.8^2)*11.5=12762.72[/tex] cubic meters

Hope this helps!

Answer:

[tex]12769.19m^{3}[/tex]

Step-by-step explanation:

The formula for the area of a circle is:

[tex]\pi r^{2}[/tex]

To work this out you would first have to find the area of the circle. To do this you would first divide 37.6 by 2, which gives you 18.8. Then to find the area you would multiply pi by 18.8 squared, which gives you [tex]1110.36m^{2}[/tex]. Then To find the volume you would multiply 1110.36 by 11.5, which gives you [tex]12769.19m^{3}[/tex].

To find the volume of a prism you would find the area of the main face and multiply it by the height.

1) Divide 37.6 by 2.

[tex]37.6/2=18.8[/tex]

2) Multiply [tex]\pi[/tex] by 18.8 squared.

[tex]\pi *18.8^{2}=1110.36m^{2}[/tex]

3) Multiply 1110.34 by 11.5.

[tex]1110.36*11.5=12769.19m^{3}[/tex]

Remember when finding the area, thee answer is always going to be squared.

Remember when finding the volume the answer is always going to be cubed.

Option B) [tex]28\pi\text{ m}^3[/tex]

Step-by-step explanation:

We are given the following in the question:

Radius of cylinder, r  = 2 m

Height of cylinder, h = 7 m

We have to find the volume of the cylinder.

Volume of cylinder =

[tex]V = \pi r^2 h[/tex]

where r is the radius and h is the height of the cylinder.

Putting values, we get,

[tex]V = \pi (2)^2(7)\\V = 28\pi\text{ cubic meter}[/tex]

Thus, the volume of cylinder is

Option B) [tex]28\pi\text{ m}^3[/tex]

Step-by-step explanation:

The system of equations that matches the graph is

x + y = 2
3x - y = 1

What is the system of equations

From the question, we are to write a system of equations for the two straight lines shown

To do this, we will pick two points on each line

Red line:

(0, 2) and (2, 0)

Using the formula,

y - y1 / x - x1 = y2 - y1 / x2 - x1

(y - 2) / (x - 0) = (0 - 2) / (2 - 0)

Simplifying

(y - 2) / x = -2 / 2

(y - 2) / x = -1

y - 2 = -x

Thus,

x + y = 2

Blue line:

(1, 1) and (0, -2)

Using the formula,

y - y1 / x - x1 = y2 - y1 / x2 - x1

(y - 1) / (x - 1) = (-2 - 1) / (0 - 1)

Simplifying

(y - 2) / (x - 1) = -3/ -1

(y - 2) / (x - 1) = 3

y - 2 = 3(x - 1)

y - 2 = 3x - 3

Thus,

3x - y = -2 + 3

3x - y = 1

Hence,

The system of equations is

x + y = 2
3x - y = 1

Answer:

a) both have the same spread

Step-by-step explanation:

Mean of Brand A > Mean of Brand B

Median of A > Median of B

Spread of:

A: 22 - 18 = 4

B: 18 - 14 = 4

The spread of the data which is obtained by calculating the Interquartile range of each distribution since the distributions are skewed is 2 for brand A and brand B. Hence, the spread is the same.

The distribution of BRAND A chips :

18, 19, 19, 19, 19, 19, 19, 20,20,20,20,20,20,21,21,21,21,21,21,22

The Upper quartile, Q3 ;

Q3 = 0.75 × (n + 1)th term

Q3 = 0.75 × 21 = 15.75 th term = 21

The Lower quartile, Q1 ;

Q1 = 0.25 × (n + 1)th term

Q1 = 0.25 × 21 = 5.25 th term = 19

The IQR = Q3 - Q1 = (21 - 19) = 2

The distribution of BRAND B chips :

14,14,14,14,14,14,14,14,15,15,15,15,15,15,16,16,16,16,16,18

The Upper quartile, Q3 ;

Q3 = 0.75 × (n + 1)th term

Q3 = 0.75 × 21 = 15.75 th term = 16

The Lower quartile, Q1 ;

Q1 = 0.25 × (n + 1)th term

Q1 = 0.25 × 21 = 5.25 th term = 14

The IQR = Q3 - Q1 = (16 - 14) = 2

Therefore, the spread of distribution of BRAND A and B are the same.

The length of the envelope is 6.3 inches

Step-by-step explanation:

Width of the envelope = 3 inches

Diagonal of the envelope = 7 inches

To find:

The length of the envelope.

Let the length of the envelope be 'l'

We can use pythogoras theorem to calculate the length.

l = √(49-9)

l = √(40)

l = 6.3 inches

The length of the envelope is 6.3 inches
