Answer:

18 minutes to run a mile

Step-by-step explanation:

1.5 is equal to 150%. so given that you have 12 minutes you can do what is 150% to 12 so 100% of 12 is 12 and 50% of 12 is 6 and 6 + 12 is 18

Answer:

then multiply by 100

[tex].8 \times 100 = 80[/tex]

then you add the percent symbol

Answer:

165

Step-by-step explanation:

First we need to find the area of the field, A = r^2 * pi

The radius is 290 / 2 = 145 feet

A = 145 * 145 * 3.14 = 66018.5 sqr feet

One bag covers 400 sqr feet

Divide the Area by 400 sqr feet to find number of bags needed.

66018.5 / 400 = 165

He will need at least 165 bags to cover the field

Answer:

Step-by-step explanation:

Answer:

30 ≤ 4 • s

or

30 ≤ 6 • s

Answer:

See below:)

Step-by-step explanation:

a)

mean = 63.6 , s.d = 2.5. We need to compute Pr(58 <= X <= 80)

The corresponding z-values needed to be computed

z1 = (58 - 63.6)/2.5 = -2.24

z2 = (80 - 63.6)/2.5 = 6.56

Therefore, we get:

Pr(58 <= X <= 80) = Pr( (58 - 63.6)/2.5 <= Z <= (80-63.6)/2.5 ) = Pr(-2.24 <= Z <= 6.56)

= 1 - 0.0125 = 0.9875

98.75 % of the women meet the requirements,Hence not too many women are being denied the opportunity to join this branch of the millitary.

b)

z value for lower 1% = -2.3263

corresponding x value = 63.6 - (2.5X2.3263) = 57.78

Z value for upper 2% = 2.0537

corresponding x value = 63.6 + (2.5X2.0537) = 68.73

The new height requirements is between 57.78 and 68.73 inch

Answer:

[tex]y = 3^{-x-2}[/tex]

Step-by-step explanation:

Since the graph is exponential, the default form of formula is going to be:

y = aˣ;

First question is, what information do we have?

I can see 3 distinct points: (2, 1), (1, 3) and (0, 9);

Normal exponential curve have a positive gradient at every point, increasing as you proceed along the x-axis to ∞;

The opposite is true of the graph in the image which tells us it is reflected in the y-axis as compared to a default exponential graph;

Any exponential function will have the point (0, 1);

Considering we have (2, 1), there seems to be a translation of 2 units rightwards;

Then considering the pattern of the y-values of the points identified above, which is 1, 3 and 9;

3⁰ = 1, 3¹ = 3 and 3² = 9;

This suggests a = 3;

We then combine this like so:

So, if we start with f(x) = 3ˣ

Then we need to apply the transformations identified above in the order of stretching, then reflections and finally translations;

Applying the reflection first;

[tex]g(x) = f(-x) = 3^{-x}[/tex]

Then, the translation of 2 units rightwards like so;

[tex]g(x-2) = 3^{-(x-2)}[/tex]

There is no apparent stretching, there could be, but, we don't know so, best thing to do is to test what we have thus far and check if it matches the graph in the image;

So, we end up with:

[tex]y = 3^{-x-2}[/tex]

Now, to test this;

Let x = 0, then:

[tex]y = 3^{-(0)+2} \\\\ y = 3^{2} \\\\ y = 9[/tex]

This matches (0, 9);

Similarly, when x = 1, then y = 3;

And x = 2, then y = 1;

This matches the graph, so this seems to be the equation of the graph.

Answer:

Step-by-step explanation:

total cups to make green paint:  36/15

total cups of blue paint in green paint:  18/15

18/15 is what % of 36/15

(18/15) ÷ (36/15) = x÷100

the above proportion can be simplified to be:

(6/5) ÷ (12/5) = x÷100

cross-multiply to get:

(12/5)x = 600/5

x = (600/5) · (5/12)

x = 50

x = 1

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Step-by-step explanation:

The rectangular coordinate of [tex]\mathbf{(4,\pi)}[/tex] is (-4,0)

The polar coordinate is given as:

[tex]\mathbf{(4,\pi)}[/tex]

To represent the polar coordinates properly, we make use of:

[tex]\mathbf{(r,\theta) = (4,\pi)}[/tex]

Where r represents radius

The rectangular coordinate is represented as: (x,y)

Where:

[tex]\mathbf{x = rcos(\theta)}[/tex]

[tex]\mathbf{y = rsin(\theta)}[/tex]

So, we have:

[tex]\mathbf{x = 4 \times cos(\pi)}[/tex]

Evaluate cos(pi)

[tex]\mathbf{x = 4 \times -1}[/tex]

Multiply

[tex]\mathbf{x = -4}[/tex]

Similarly,

[tex]\mathbf{y = 4 \times sin(\pi)}[/tex]

Evaluate sin(pi)

[tex]\mathbf{y = 4 \times 0}[/tex]

Multiply

[tex]\mathbf{y = 0}[/tex]

Recall that the rectangular coordinate is represented as (x,y)

Hence, the rectangular coordinate of [tex]\mathbf{(4,\pi)}[/tex] is (-4,0)

The slope of the line is  

✔ 7/3

The y-intercept is at  

✔ –3

The graph represents the function  

✔ g(x) = (7/3)x–3

Step-by-step explanation:

these are the right answers i got them right on edg 2021

The slope of the line is 7/3

The y-intercept is at y=-3

The graph represents the function 3y-7x + 9=0

What is slope of line ?

Slope of line is the angle made by the line from positive x-axis in anticlockwise direction, it also denoted the steepness of the line.

It is given that a coordinate plane with a straight line with a positive slope passing through the points, (0,-3) and (3, 4)

How using slope formula to find the slope m of line :

m = (y₂-y₁)/(x₂-x₁)

m = (4+3)/(3-0)

m = 7/3

Let us first find the equation of the line using point slope equation of line, Substituting all the values in above equation to get the equation of line :

(y-y₁) = m(x-x₁)  

(y+3) = 7/3(x-0)

3y+9 = 7x

3y-7x + 9=0

Now, for y-intercept x= 0 that is :

3y-7x + 9=0

3y -0+9=0

3y = -9

y = -3

Therefore, the slope of the line is 7/3

The y-intercept is at y=-3

The graph represents the function 3y-7x + 9=0
