Step-by-step explanation:

Let the total number of flowers planted be 1

Given

Number of roses = 1/3

Fraction of daises = 3/6

Required

Fraction of tullips

Fraction of tullips = 1-(1/3+3/6)

Fraction of tullips = 1-(2+3/6)

Fraction of tullips = 1-5/6

Fraction of tullips = 1/6

Hence the fraction of tulip left is 1/6

Step-by-step explanation:

Answer:

For any exponential function in which the base is less than 1, it will be an exponential decay situation.  In this problem, the base is 0.97.  The amount that the base is less than 1  ( i.e. 1 - base) represents, in decimal form, the percent of decrease, which in this case is 0.03 or 3%.  

Step-by-step explanation:

The formula for exponential decay is y=a(1-r)x.  

r is the decay rate.

Answer:

F. (-4, oo)

Step-by-step explanation:

Start from the left side.

The arrow on the left side shows that the graph continues increasing forever as x decreases. Beginning at the highest value of y you see on the left side at point (-6, 5), as x increases, moving right along the x-axis, the y-values decrease. When you get to x = -4, y is at its lowest value which is 1.

Starting just to the right of x = -4, the y-values begin to increase from the lowest y-value of 1. The arrowhead at the right side top shows that the curve continues increasing forever to infinity.

The values of x for which y increases are all values greater than -4 and all the way to positive infinity.

This function is increasing for x > -4.

Now we need to write x > -4 in interval notation.

In interval notation, use a curved parenthesis to mean a number that is not included. The interval starts at -4, so it starts as

(-4

Then you write a comma to separate from the value where the interval ends.

(-4,

The interval in x of increasing values goes to positive infinity, so now you write the infinity symbol, and you close the interval with a curved parenthesis. By convention, infinity always gets a curved parenthesis. Also, I'll use oo for infinity below.

(-4, oo)

Answer: F. (-4, oo)

Answer:

We conclude that:

f(x) = 5 for x =  -7, -6, -5, -4, -3, -2, -1, 0 and 2.

Step-by-step explanation:

From the diagram, it is clear that:

There are two parts of the graph:

LEFT GRAPH

On the left side, the graph of the function indicates that the value of y remains  5 for the values x = -7, -6, -5, -4, -3, -2, -1, and 0.

In other words,

f(x) = 5, for x = -7, -6, -5, -4, -3, -2, -1, and 0.

RIGHT GRAPH

On the right side, the graph of the function indicates that the value of y is 5 at x = 2

In other words,

f(x) = 5, for x = 2.

Therefore, we conclude that:

f(x) = 5 for x =  -7, -6, -5, -4, -3, -2, -1, 0 and 2.

The additive inverse of the polynomial 7x-20 is -7x+20.

The given algebraic expression is 7x-20.

The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.

Here, the additive inverse of given polynomial is

-7x+20

Therefore, the additive inverse of the polynomial 7x-20 is -7x+20.

Explanation:

For any 45-45-90 right triangle, the hypotenuse H is always sqrt(2) times the leg L

In terms of symbols, we can say

[tex]H = L*\sqrt{2}[/tex]

We're told the hypotenuse is e, so H = e

Let's solve for L in terms of e

[tex]H = L*\sqrt{2}\\\\e = L*\sqrt{2}\\\\L*\sqrt{2} = e\\\\L = \frac{e}{\sqrt{2}}\\\\[/tex]

Now let's multiply top and bottom by [tex]\sqrt{2}[/tex] to rationalize the denominator

[tex]L = \frac{e}{\sqrt{2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{2}*\sqrt{2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{2*2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{4}}\\\\L = \frac{e\sqrt{2}}{2}\\\\[/tex]

If the hypotenuse is e, then the length of each leg is [tex]\frac{e\sqrt{2}}{2}[/tex]

This matches with choice C, which is one of the two answers. This allows us to rule out choices A and B, as those expressions are not equivalent to the expression for choice C.

----------------

The two legs of any right triangle form the base and height. The order doesn't matter. The base is always perpendicular to the height. In a right triangle, the two legs are always perpendicular.

The base and height are [tex]\frac{e\sqrt{2}}{2}[/tex] each.

The area of the triangle is...

[tex]\text{Area} = \frac{1}{2}*\text{base}*\text{height}\\\\\text{Area} = \frac{1}{2}*\frac{e\sqrt{2}}{2}*\frac{e\sqrt{2}}{2}\\\\\text{Area} = \frac{e\sqrt{2}*e\sqrt{2}}{2*2*2}\\\\\text{Area} = \frac{e*e\sqrt{2*2}}{2*2*2}\\\\\text{Area} = \frac{e^2\sqrt{4}}{2*2*2}\\\\\text{Area} = \frac{e^2*2}{2*2*2}\\\\\text{Area} = \frac{e^2}{2*2}\\\\\text{Area} = \frac{e^2}{4}\\\\[/tex]

This matches with choice E, which is the other answer. Choices D and F are eliminated as they are not equivalent to the expression for choice E.

The required points that are correct are the length of the leg is given as e√2/2 and the area of the triangle is given as e²/4. Options D and E are correct.

Given that,
An isosceles right triangle has a hypotenuse of length e.

In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.

Here,
Let the measure of the leg be x,
Apply Pythagoras' theorem,
e² = x ² + x²
e² = 2x²
x = √e²/2
x = e/√2
or
x = e√2/2

Now,?
area of the triangle is given as,
area = 1/2 × e/√2 ×e/√2
area = e² / 4

Thus, the required points that are correct are the length of the leg is given as e√2/2 and the area of the triangle is given as e²/4. Options D and E are correct.

#SPJ2

Answer:

108 student tickets, and 176 adult tickets  were sold

Step-by-step explanation:

Adult ticket $8  Call the number of adult tickets sold "a"

Student ticket $5  Call the number of student tickets sold "s"

Since we are talking about TWO consecutive days of sold out seats, the total number of seats sold were 2* 142 = 284

Then we create two different equations with the information given:

a + s = 284

8 * a + 5 * s = 1948

we can solve for s in the first equation as follows: s = 284 - a

and use it in the second equation

8 a + 5 (284 - a) = 1948

8 a + 1420 - 5 a = 1948

combining

3 a = 528

a = 528/3

a = 176

we find the number of student tickets using this answer in the substitution equation we used:

s - 284 - 176 = 108

Therefore 108 student tickets, and 176 adult tickets  were sold.

sqrt81 is 9 which is a whole number it is rational

sqrt16 is 4 which again is a whole number and is rational

1.9 is rational because it can be written as a fraction or ratio

but sqrt39 is a repeating decimal that goes on forever it still is a real number not fitting into the imaginary category but not a ration number.

After 1 year = $2548

Step-by-step explanation:

Answer:

Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.

Step-by-step explanation:

Distance Tony ran last week are

6.25 km

4 km 750 m

872 km (Note: This would be 8 [tex]\frac{1}{2}[/tex] km and not 872 km)

We will add all the distances to check if they sum up to 20km or not.

First we will convert 4 km 750 m into km

We know that 1000 m = 1 km

So, 1 m = 1/1000 km

750 m = 750/1000 = 0.75 km

Now 4km + 0.75 km = 4.75 km

So, 4 km 750 m = 4.75 km

and 8 [tex]\frac{1}{2}[/tex] km = 8.5 km

Now, finding Distance covered by Tony during last week = 6.25 km + 4.75 km + 8.5 km

= 19.5 km

So, Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.
