Answer and explanation:
The ratio 1:2 is different from the ratio 2:1. The ratio 1:2(one to two) means a comparison of two sizes; the ratio of one part of that thing to the ratio of two parts of that thing. Likewise, the ratio 2:1 is the comparison of two parts of a thing to the ratio of one part of the thing. For the ratio 2:1, we could say for example that for every two crushed tomatoes there is one tomato paste.

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted. Since then, it has grown approximately 0.5 centimeter per day.
a. Write a rule to describe the function.
b. After how many days will the zucchini plant be 0.195 meter tall?
A. h(d) = 12d + 0.5; 1.3 days
B. h(d) = 0.5d +12; 15 days
C. h(d) = 0.5d; 39 days
D. h(d) = d/0.5 = 12; 4 days
Answer:
B. h(d) = 0.5d +12; 15 days
Step-by-step explanation:
here they want to write an equation to describe the growth of the plant. set y = height of the plant (in cm). set x = days (since planting). the plant was planted on day 0 (x=0). We know that the plant was 12 cm tall when it was first planted, so we know that y(0) = 12 cm. y(0) just means the value of the equation y when x = 0, or y(x=0), or just y(0). Every day the plant grows .5 cm so we know the value of y will increase at .5cm for every x days, or .5x. Add the initial value of y (where x=0) and you have the equation y = 12 + .5x (in cm). usually we write equations in meters and not cm, so you can change it to y = .12 +.005x (in meters).
now just set your equation equal to .185 meters and solve for x
.185 = .12 + .005x
.065 = .005x
x = 13 days
Answer
(a) Find out the a rule to describe the function.
To prove
Let us assume that the days be represted by d .
Let us assume that the height of plant be represted by y.
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
Than the function becomes
y = 12 + 0.5 × d
y = 12 + 0.5d
(b) Find out after how many days will the zucchini plant be 0.195 meter tall .
To prove
Let us assume that the days be represted by d .
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
As
1meter = 100cm
0.195 meter convert into centimeter.
= 19.5cm
Than the equation becomes
12 + 0.5d = 19.5
0.5d = -12 + 19.5
0.5d = 7.5
d = 15 days
Therefore 15 days will the zucchini plant be 0.195 meter tall .
a) 12 + 0.5d d=day
b) 0.195/0.5=0.39d
Answer:
15 days will the zucchini plant be 0.195 meter tall .
Step-by-step explanation:
(a) Find out the a rule to describe the function.
To prove
Let us assume that the days be represted by d .
Let us assume that the height of plant be represted by y.
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
Than the function becomes

y = 12 + 0.5d
(b) Find out after how many days will the zucchini plant be 0.195 meter tall .
To prove
Let us assume that the days be represted by d .
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
As
1meter = 100cm
0.195 meter convert into centimeter.
= 19.5cm
Than the equation becomes
12 + 0.5d = 19.5
0.5d = -12 + 19.5
0.5d = 7.5
d = \frac{7.5}{0.5}
d = 15 days
Therefore 15 days will the zucchini plant be 0.195 meter tall .

Find the rate of change of the function by using two points from the table.
x y
1 15
2 11
3 7
4 3
The rate of change of the function is -4.
What is the slope of a line?The slope of a line indicates the direction and the steepness of the line. The formula for the slope of a line passing through the points (x₁,y₁) and (x₂, y₂) is m = (y₂-y₁)/(x₂-x₁).
Consider the two points (1,15) and (2,11).
The rate of change of the function is nothing but the slope of the line passing through the points (1,15) and (2,11) which is:
m = (11 - 15)/(2 -1)
m = -4
Hence, the rate of change of the function is -4.

Carol opened a savings account and deposited 2,650. The account earned 4% interest compounded annually how much money will carol have in her account after 3 years
Answer:
$2968
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
I = 2650 × 0.04 × 3 = 318
I = $ 318.00
The simple interest accumulated
on a principal of $ 2,650.00
at a rate of 4% per year
for 3 years is $ 318.00.

Step-by-step explanation:
12/15 can be simplified as 4/5, 4/5 can be rewritten as 8/10, or 80%. 0 is of course 0%, 1/2 is 50%, and 1 is 100%. 80% is closest to 100%, so 12/15 is closest to 1.

What is compound interest?
Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Compound interest formula[tex]CI = P(1+\frac{r}{n}) ^{nt} -P[/tex]
and, the Amount is given by
[tex]A = P(1+\frac{r}{n} )^{nt}[/tex]
Where,
A is amount
P is principal
r is rate of interest
n is number of times interest is compounded per year
t is time
According to the given question
Principal, P = $210
Amount, A = $250
Time, t = 5 years
n = 1
Therefore, the interest rate is given by
Amount = [tex]P(1+\frac{r}{n}) ^{nt}[/tex]
⇒[tex]250 = 210(1+\frac{r}{1}) ^{5}[/tex]
⇒[tex]\frac{250}{210} =(1+r)^{5}[/tex]
⇒[tex]1.19 = (1+r)^{5}[/tex]
⇒[tex]\sqrt[5]{1.19} = 1+r\\[/tex]
⇒ 1.035 = 1 + r
⇒ r = 1.035 - 1
⇒ r = 0.35
Hence, the interest rate is o.35.

A store offers a 30% discount on a clarinet that was marked up by 5% form the original retail price for $405.the sales tax is 9%. What does the clarinet cost?.
Answer:
$324.46
Step-by-step explanation:
$405 × 0.05= $20.25 is how much it is marked up if the original price is $405.
$405 +$ 20.25 = $425.25 is the new total of the clarinet
Now 30 % of $425.25... $425.25×0.30= $127.58 is what 30% is.
You have to subtract th $127.58 from $425.25 to get the discounted price.
$425.25 - $127.58 = $297.67
Next you have to calculate for the 9% and add it to the discounted price.
$297.67 × .09 = $26.79
$297.67 + $26.79= $324.46
$324.46 is the cost of the clarinet.

If you know that Indy and Fort Wayne are actually 120 miles apart, how far apart would Indy and Kokomo be in real life? Express your answer rounded to the nearest tenth of
Answer: 60 miles
Step-by-step explanation:
On a map, Indy and Fort Wayne are 19 centimeter apart while Kokomo and Indy are 9.5 cm apart on the map.
In real life, Indy and Fort Wayne are actually 120 miles apart, the distance between Indy and Kokomo in real life would then be:
= 9.5 × 120/19
= 120/2
= 60 miles
Indy and Kokomo are 60 miles apart in real life.
