Answer:
[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]
[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex] --- Distributive property
Step-by-step explanation:
Given
Ferns = 4
Palms = 2
Lillies = 10
Shrubs = 8
Required
Show the total cost of plants as an expression
Shorten it using the distributive property
First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;
So, 4 Ferns = 4F
2 Palms = 2P
10 Lilies = 10L
8 Shrubs = 8S
Total Plants = Summation of the above parameters
[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]
The above expression represents the total plants bought;
Now, to apply the distributive property; we simply look for a common factor;
In this case, the common factor is 2;
So, [tex]Total Plants = 4F + 2P + 10L+ 8S[/tex] becomes
[tex]Total Plants = 2(\frac{4F}{2} + \frac{2P}{2} + \frac{10L}{2}+ \frac{8S}{2})[/tex]
[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex]

1. How do you use the distance formula and slope formula to classify a quadrilaterals and triangles
Answer:
Both Distance formula and Slope formula are used to classify quadrilaterals and triangles, as Distance formula is used to calculate the length of each side while Slope formula is used to find the angle of a line with respect to an axis or another line.
We can classify the figure as finding the lengths of each side by using Distance formula. For example, if we find that a quadrilateral has all 4 sides equal, is it a square. If it has opposite sides equal, it can be a rectangle or a parallelogram, and so on. It can also tell whether a triangle is right angled, isosceles or equilateral.
Slope are used to find angles of the lines. If 2 lines have the same slope, it means they are parallel to each other. If the product of their slopes is -1, it means they are perpendicular to each other

Consider the below equation:
0.5x-7= sqrt(-5x+29)
Give 2 different ways to show that the equation does not have any solutions. One way must be solving algebraically, and the other way must be by graphing.
Answer:
Algebraically
0.5x-7= √(-5x+29)
(0.5x-7)² = -5x+29
(0.5x)² - 2*0.5x*7 + 7² = -5x+29
0.25x² - 7x + 49 + 5x - 29 = 0
0.25x² - 2x + 20 = 0
Its discriminant is:
b² - 4*a*c
(-2)² - 4*0.25*20
-16 < 0
Therefore, the equation has no solutions.
Graphically
In the picture attached, the plots of the functions are shown. We can see that they don't intersect each other, and that is why there is no solution.

pythagorean therom 1.6^2+3^2=x^2
Answer:
x = 3.4
Step-by-step explanation:
→You can use the Pythagorean Theorem to solve this:
[tex]a^2+b^2=c^2[/tex]
→The "a," and "b," are the legs, 3 and 1.6, and the "c," is the hypotenuse, which we are trying to find.
[tex]1.6^2+3^2=c^2[/tex]
[tex]2.56 + 9 = c^2[/tex]
→Add like terms (2.56 and 9) together:
[tex]11.56 = c^2[/tex]
→We need to get "c," by itself, and to do this we need to square root both sides, like so:
[tex]\sqrt{11.56} =\sqrt{c^2}[/tex]
[tex]3.4 = c[/tex]

Antonina needs to have worked at least 90 volunteer hours to graduate. She has already volunteered with a housing organization over the summer for 52 hours. Antonina needs to tutor after school for 3 hours per week to complete the remainder of her volunteer hours. If w is the number of weeks that Antonina needs to tutor in order to complete her volunteer hours, which of the following inequalities best models the situation described above?
Answer:
No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate
=> 52 + 3w >= 90
Step-by-step explanation:
Given that Antonina needs to have worked at least 90 volunteer hours to graduate means that she needs to volunteer either for 90 hours or more than that . Mathematically this can be written as
Total volunteer hours required to graduate greater than or equal to 90
Total volunteer hours required to graduate>= 90
No. of hours already volunteered = 52
no. of hours left for volunteering = Total volunteer hours required to graduate - No. of hours already volunteered = 90 - 52 = 38
No. of hours in one week she can dedicate for volunteering= 3
if w is the number of weeks that Antonina needs to tutor in order to complete her volunteer hours
then total volunteer hours dedicated in w weeks will be = w*No. of hours in one week she can dedicate for volunteering = w*3 = 3w
Thus,
No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate
=> 52 + 3w >= 90
Two friends, Terrence and Eric share a certain amount of money in the ratio 5:9. If Terrence gets $56 less than Eric find the total amount of money that is shared between the two boys.
Answer:
239.556
Step-by-step explanation:
Difference of ratio=9-5=4
Sum of ratio=9+5=14
we know that Eric got $56 more
which means
4/14=56
1/14=56/4
1/14=14
1=14*14
=196
now we need to find
9/14=(196*14)/9
= 239.556
For every 12 slices of pizza sold at Ping's Pizza Shop,
3 slices are pepperoni, 4 are sausage, and the rest are
cheese. What is the ratio of pepperoni to cheese?
Answer:
3:5 Is the ratio because there are five pieces of cheese.
Step-by-step explanation:
If there are 12 pieces, then you can add 4 and 3 together and get 7 and then you can take 7 from 12 and get 5 which is how many cheese pieces there are. Now you know that there are 3 slices of pepperoni and 5 pieces of cheese. Therefore the ratio is 3:5.

Darren and Quincy wanted to justify that the expression One-sixth (6 x + 12) minus one-half (4 x + 2) is equivalent to Negative x + 1. Their justifications are shown below. Darren’s Method: Substitute 2 into both expressions One-sixth (6 x + 12) minus one-half (4 x + 2) = one-sixth (6 (2) + 12) minus one-half (4 (2) + 2) = one-sixth (24) minus one-half (10) = negative 1. negative x + 1 = (negative 2) + 1 = negative 1 Quincy’s Method: Substitute 6 into both expressions One-sixth (6 x + 12) minus one-half (4 x + 2) = one-sixth (6 (6) + 12) minus one-half (4 (6) + 2) = one-sixth (48) minus one-half (26) = negative 5. negative x + 1 = (negative 6) + 1 = negative 5 Which explains who is correct? Only Darren is correct because he substituted x = 2 into the expressions. Only Quincy is correct because he substituted a number that is the same as the denominator of one of the fractions. Both are correct because after substituting the same value into both expressions, the result is the same. Both are correct because after submitting different values into each expression, the result is the same.
Answer:
Both are correct because after substituting the same value into both expressions, the result is the same.
Step-by-step explanation:

If a circle has a radius of 7 square root of 2 and it has a shaded region with an area of 34 pi, find the angle within the shaded region.
Answer:
The angle of the shaded region is 124.9°
Step-by-step explanation:
Since there's an region inside the circle that is shaded and has an area of 34 pi square units, we can apply the circle's sector area's formula in order to find the angle of this region. The formula is given by:
[tex]\text{sector area} = \frac{\text{angle}*\pi*r^2}{360}\\[/tex]
Applying the data from the problem gives us:
[tex]34*\pi = \frac{angle*\pi*(7*\sqrt{2})^2}{360}\\34 = \frac{angle*(49*2)}{360}\\98*angle = 34*360\\angle = \frac{12240}{98} = 124.9\°[/tex]
The angle of the shaded region is 124.9°
Write the slope intercept form through (-1, -1), perp to y= 1/3x -3
Answer:
y = - 3x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute (- 1, - 1) into the partial equation
- 1 = 3 + c ⇒ c = - 1 - 3 = - 4
y = - 3x - 4 ← equation of perpendicular line
