The Chemistry Club is experimenting with different mixtures of water with a
certain chemical to make fake snow.
To make each mixture, the students start with some amount of water, and then add
1/7 of that amount of the chemical, and then 9 more grams of the chemical. The
chemical is expensive, so there can't be more than a certain number of grams of the
chemical in any one mixture. How much water can you start with so that you don't
use up too much of the chemical?
a. 1/7x + 9 < 26.25
b. 9x + 1/7 s 26.25
26.25x + 9 = 1/7
C.
d. 1/7x + 26.25 39
Answer:
Suppose we have with x, the amount of water we use (in grams).
1/7 of this will be the chemical, then we have (1/7)*x grams of chemical.
Then we add another 9g of the chemical, then we have in total:
(1/7)*x + 9g of the chemical.
And we know that the chemical is expensive, so there can't be more than a given number of grams of the chemical, because of the phrase:
"...There can't be more than..."
We will have a relation like:
(1/7)*x + 9g ≤ something.
By looking at the options, we can see that "something" = 26.25 grams
then we will have the inequality:
(1/7)*x + 9g ≤ 26.25 g
Now we can solve this for x, the amount of water used:
(1/7)*x ≤ 26.25 g - 9g
x ≤ (26.25 g - 9g)*7
x ≤ 120.75 grams
This means that the maximum amount of water we can use is 120.75 grams of water.
A roller coaster is being designed that starts at (0,22) and ends at (19,2),
Along the ride there is a relative minimum at (5,6) and a relative
maximum at (10,18). The roller coaster is almost finished but one
section is missing. Find the correct function that completes the roller
coaster so that the ride is smooth and continuous.
Answer:
The function is, f(x) = 6·sin((π/5)(x + 3π/2)) + 12
Step-by-step explanation:
The general form of equation of a roller coaster is given as follows;
y = A·sin(B(x - C)) + D
Where;
A = The amplitude = (18 - 6)/2 = 6
D = The vertical shift = 12
One revolution = 10 unit
∴2·π = 10 unit
Therefore, 10 = 2·π/B
B = 2·π/10
The phase shift = 3·π/2
Therefore, we have the function as follows;
f(x) = 6·sin(2·π/10(x + 3π/2)) + 12 = 6·sin((π/5)(x + 3π/2)) + 12

Answer:
Part A: Choice 3) Reasonable. The grapes and apples is about 2 cups and pears and oranges is exactly 3 cups.
Part B: Exactly 4 11/12 cups
almost equal to 5 cups
Step-by-step explanation:
The missing part of the question is :
2 1/2 cups of pears. 2/3 cup of grapes 1 1/4 cups of apples 1/2 of orange slices .
Pears + apples
2 1/2+1 1/4 =

Reasonable. The pears and apples is about 3 cups and the grapes
and oranges is exactly 2 cups. This statement is wrong.
Grapes and oranges
2/3 + 1/2
= 4+3/6
=7/6
=1 1/6 cups
grapes and apples
2/3 cup of grapes 1 1/4 cups of apples
2/3 + 5/4
= 8+15/12

= 1 11/12 cups
pears and oranges
2 1/2 cups +1/2 of orange slices
3 cups
Reasonable. The grapes and apples is about 2 cups and pears and
oranges is exactly 3 cups. this statement is true as shown above.
N.B the answer may vary due to the different measurements given in the missing part of the question.
Part B:

A)
175 cm
B)
196 cm?
C)
216 cm?
D)
222 cm?
Answer:
222 cm²
Step-by-step explanation:
Each triangle's area is 6 cm², each side rectangle's area is 75 cm², and the bottom rectangle's area is 60 cm². Since there are two triangles, two side rectangle's, and one bottom rectangle, you would add all of their areas together:
6 + 6 + 75 + 75 + 60 leads you to the answer of 222 cm².
PLEASE HELP ME KSDAKJDSAJDJKS
Answer: x = 16

Order the sides of each triangle from shortest to longest.
Answer:
FG, GH, FH
Step-by-step explanation:
H=180-100-50=30°
Since H is the smallest degree, the side opposite it (FG) is the shortest length.
Since F is the middle degree, the side opposite it (GH) would be the middle length.
Since G is the highest degree, the side opposite it (FH) would be the longest.

What is the median of the data set?
9
8.5
8
10
Answer:
8.5
Step-by-step explanation:
When you write out the data set, it looks like this:
5, 8, 8, 8, 8, 9, 9, 9, 10, 10
The median means the exact middle of the data set. In this case, it falls between the 8 and the 9, so the middle would be 8.5, so that's the median of the set. I hope this helps :)
Answer:
The median is 8.5
Step-by-step explanation:
The median is the middle number in a data set. For example, if you had a data set:
2, 2, 3, 4, 4
You would go forwards and backwards in the set until you found the middle number, which is 3. 3 would be the median.
However, if there is no middle number (there are an even number of points in the set), you add the two remaining numbers and divide it by two.
For example, if the final two numbers were:
2, 6
You would add 2 and 6 to get 8, and divide by 2, and you get the median 4.
In this set, we have
5, 8, 8, 8, 8, 9, 9, 9, 10, 10.
The final two numbers are 8 and 9, so you add 8+9=17, divided by 2 = 8.5.

Janet Foster bought a computer and printer at Computerland. The printer had a $880 list price with a $100 trade discount and 2/10, n/30 terms. The computer had a $4,000 list price with a 25% trade discount but no cash discount. On the computer, Computerland offered Janet the choice of (1) paying $155 per month for 17 months with the 18th payment paying the remainder of the balance or (2) paying 7% interest for 18 months in equal payments.
a. Assume Janet could borrow the money for the printer at 7% to take advantage of the cash discount. How much would Janet save? (Use 360 days a year. Round your answer to the nearest cent.)
Part A (Printer): $12.63
Part B (Computer): $180.83
Step-By-Step
A:
"take advantage of the cash discount" Since Janet is taking the cash discount we need to use the terms.
2/10 => Means if paid in 10 days apply a 2% discount
($880 - $100) = $780 (This is because of the trade discount stated also)
$780 * 0.98 = $764.40
(Note: 0.98 is the term "2/10" it is the 2% discount, represented as (1-0.02) )
$764.40 * 0.07 * (20/360) = $2.9726666 (Note: Here 20/360, 20 represents the rest of the days left in the term agreement)
No Discounts: ($780 - 764.40) = $15.60
Discounts: $2.9726666
How much would Janet save?
$15.60 - $2.9726666 = $12.62733 = $12.63
===============================================
Question has a part B:
"On the computer, what is the difference in the final payment between choices 1 and 2?"
Note: Computer Price w/ Trade Discount => $4,000 - ($4,000*0.25) = $3000
(1) "$155 per month for 17 months" => $155 × 17 = $2,635
Last payment $3,000 – $2,635 = $365
(2)-------------- Note: 18 Months = 1.5 Years
$3,000 × 0.07× 1.5 = $315
$3,000 + $315 = ($3,315) / 18 Months = $184.1666
Difference in the final payment?
$365 - $184.1666 = $180.8334 = $180.83
A. Janet would save $12.63
B. Computer: $180.83
How much would janet save ?Since Janet is taking the cash discount we need to use the terms.
"take advantage of the cash discount"
2/10 => Means if paid in 10 days apply a 2% discount
($880 - $100) = $780 (This is because of the trade discount stated also)
$780 * 0.98 = $764.40
[0.98 is the term "2/10" it is the 2% discount, represented as (1-0.02)]
$764.40 * 0.07 * (20/360) = $2.9726666 (Note: Here 20/360, 20 represents the rest of the days left in the term agreement)
No Discounts: ($780 - 764.40) = $15.60
Discounts: $2.9726666
Janet would save = $15.60 - $2.9726666 = $12.62733 = $12.63
On the computer, what is the difference in the final payment between choices 1 and 2?Computer Price w/ Trade Discount => $4,000 - ($4,000*0.25) = $3000
(1) "$155 per month for 17 months" => $155 × 17 = $2,635
Last payment $3,000 – $2,635 = $365
(2) 18 Months = 1.5 Years
$3,000 × 0.07× 1.5 = $315
$3,000 + $315 = ($3,315) / 18 Months = $184.1666
Difference in the final payment= $365 - $184.1666 = $180.8334 = $180.83

Answer:
(-14,0)
Step-by-step explanation:
lets find the equation of the line first
so lets take two points (-74,18) and (-54,12)
so slope is rise/run= -6/ 20 or -3/10
plugging into the equation
y= mx+b
we get
12= 5.4*3+b
12= 16.2+b
b= -4.2
so equation is y= -.3x-4.2
simplyfying we get
10y= -3x-42
3x= -10y-42
x= -10y-14

The equations of lines K,P,and M are given below
K: x+2y=6
P: 6x + 3y=12
M: -x+ 2y=10
which statement is true
*ANSWERS ARE IN THE PICTURE*
Answer:
M is perpendicular to KStep-by-step explanation:
Given the equations of the following line
K: x+2y=6
P: 6x + 3y=12
M: -x+ 2y=10
First we need to get the slpe of each line as shown;
For K:
K: x+2y=6
Rewrite in standard form;
2y = -x + 6
y = -1/2 x + 6/2
y = -1/2 + 3
Slope of K is -1/2
For P:
P: 6x + 3y=12
Rewrite;
3y = -6x + 12
y = -6/3 x + 12/3
y = -2x + 4
Slope of P is 2
For M;
M: -x+ 2y=10
Rewrite
2y = x + 10
y = 1/2 x + 10/2
y = 1/2 x + 5
Slope of M is 1/2
Taking the product of slope K and P
Mk * Mp = -1/2 * 2
Mk * Mp = -1
Since the slope of K and P is -1, hence line M and line P are perpendicular
