Answer:
I need points bro
Step-by-step explanation:
Answer: B) rose bush: $6, geranium $7
Step-by-step explanation:
Jose spent $70 on 7 rose bushes and 4 geraniums.
( 7 x $6 = $42 ) ( 4 x $7 = $28 )
$42+$28= $70
Eugene spent $50 on 6 rose bushes and 2 geraniums.
( 6 x $6 = $36 ) ( 2 x $7 = $14 )
36+14 =50

The 40th percentile is (1.6 + 1.6) / 2 = 1.6
What is percentile ?
In statistics, a k th percentile is a score below which a given percentage k of scores in its frequency distribution falls or a score at or below which a given percentage falls.
The data are in ascending order.
Compute the position of the pth percentile (index i):
i = (p/100)*n
i = (40/100)*50
i = 20
The index i is an integer ⇒ the 40th percentile is the average of the values in the 19th and 20th positions (1.6 and 1.6 respectively).
Therefore, the 40th percentile is (1.6 + 1.6) / 2 = 1.6
P40=1.6 Mbps

Anna wants to purchase advertising space in the school newspaper. Each square inch of advertisement space sells for $3.00. She wants to purchase a rectangular space with length and width in the ratio 3:2 and she has up to $50.00 to spend. What are the dimensions of the largest advertisement she can afford to purchase?
(please explain how you got the answer and show me some work!!)
Answer:
The largest advertisement she can afford has dimensions of 5 in x 10/3 in
Step-by-step explanation:
Assume the dimensions of the advertisement are L and W.
The area of the advertisement is:
A = L.W
The ratio length/width is 3:2, thus the proportion is:
[tex]\displaystyle \frac{L}{W}=\frac{3}{2}[/tex]
Thus:
[tex]\displaystyle L=\frac{3}{2}W[/tex]
The area is:
[tex]\displaystyle A=\frac{3}{2}W^2[/tex]
Since the square inch of advertisement space sells for $3, the cost for Anna to purchase it is:
[tex]\displaystyle C=3\cdot\frac{3}{2}W^2[/tex]
Simplifying:
[tex]\displaystyle C=\frac{9}{2}W^2[/tex]
This cost can be a maximum of $50, thus:
[tex]\displaystyle \frac{9}{2}W^2=50[/tex]
Multiplying by 2:
[tex]9W^2=100[/tex]
Solving for W:
[tex]\displaystyle W=\sqrt{\frac{100}{9}}=\frac{10}{3}[/tex]
[tex]\displaystyle W=\frac{10}{3}[/tex]
And
[tex]\displaystyle L=\frac{3}{2}\cdot \frac{10}{3}[/tex]
L = 5
Thus the largest advertisement she can afford has dimensions of 5 in x 10/3 in

10 POINTS Solve for x:
7-2x=9x+19
A.x = 11/12
B.x = -12/11
C.x = 1
Answer:
Answer is "B"
Step-by-step explanation:
Rearrange terms: 7-2x=9x+19
-2x+7=9x+19
Subtract 7 from both sides of the equation: -2x+7=9x+19
-2x+7-7=9x+19-7
Simplify: -2x=9x+12
Subtract 9x from both sides: -2x=9x+12
-2x-9x=9x+12-9x
simplifiy: -11x=12
solution: x=-12/11

There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.
The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.
The real surface area is between 214.9 square inches and 668.3 square inches.
The mistaken surface area found by Jayden is 443 square inches.
How to determine the surface area of a right angled parallelepiped
In this problem we find a right angled parallelepiped whose dimensions are known. The surface area of the parallelepiped is the sum of the areas of the six faces. There are three pairs of faces with the following dimensions:
Pair 1
A' = (4.92 in) · (15.3 in)
A' = 75.276 in²
Pair 2
A'' = (15.3 in) · (7.28 in)
A'' = 111.384 in²
Pair 3
A''' = (4.92 in) · (7.28 in)
A''' = 35.818 in²
There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.
The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.
The range of measures for the area of the parallelepiped is represented by the following inequality:
6 · 35.818 in² < 444.956 in² < 6 · 111.384 in²
214.908 in² < 444.956 in² < 668.304 in²
The real surface area is between 214.9 square inches and 668.3 square inches.
Lastly, the mistaken surface area found by Jayden is:
A = 2 · (4.92 in) · (15.1 in) + 2 · (111.384 in²) + 2 · (35.818 in²)
A = 442.988 in²
The mistaken surface area found by Jayden is 443 square inches.

Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.
Selection of menu, food, clothes, subjects, the team are examples of combinations.
The formula for combinations is: nCr = n!/[r! (n-r)!]
nCr represents the number of combinations from “n” objects taken “r” at a time.
given that
select 6 restaurants from 11.
nCr = n!/[r! (n-r)!]
we are looking at a Combination of 11 things takes 6 at a time, or 11C6
11C6=11!/(6!5!)
11C6=11×10×9×8×7 / 5×4×3×2×1.

Water freezes at 0 degrees Celsius, which is the same as 32 degrees Fahrenheit. Also water boils at 100 degrees Celsius, which is the same as 212 degrees Fahrenheit. (Use fractions in your answers.)
(a) Use the freezing and boiling points of water to find a formula expressing Celsius temperature C as a linear function of the Fahrenheit temperature F.
I saw the same question but it kept saying the answers were wrong, so
The required equation which represents the expression of Celsius temperature as a linear function of the Fahrenheit temperature is; C = (9/5)F - 57.6.
What is the linear equation expressing the Celsius temperature in terms of the Fahrenheit?It follows from the task content that the linear equation which relates both the Celsius and Fahrenheit temperature is to be determined.
On this note, the two points which can be inferred to describe the linear relationship are;
(32, 0) and (212, 100)
Hence, the slope of the linear equation;
m = (C2 - C1)/(F2 - F1)
m = (212 - 32)/(100 - 0)
m = 180/100
m = 9/5
Hence, from the point-slope equation form; (y-y1) = m (x -x1).
We have; (C - 0) = (9/5) (F - 32)
C = (9/5)F - 57.6

Answer: formula - (x/4)+x
Step-by-step explanation:
Since there are no numbers, here is just the formula and what it means :)
(x/4)+x
(btw x is whatever your number is)
so what you need to do first is to divide your number by 4 because 25% is 1/4 of 100%
and then add that number that you just got to your number.
Its a little confusing to say out in words, so here is an example using 24
