Step-by-step explanation:
You are testing fertilizers on plants. One plant is 11 cm tall and growing at a rate of 2 cm/day. Write an equation that can be solved to find the number of days, d, it will take for the plant to be 65 cm tall.
The required equation that can be solved to find the number of days, d, it will take for the plant to be 65 cm tall is d= [tex]\frac{5.5\times 65}{11}\\[/tex]
From the question given, we are told that when testing fertilizers on a plant that is 11 cm tall, it is growing at a rate of 2 cm/day. This can be expressed as:
11cm = 2cm/dayWe can get the number of days it will take the 11cm plant to grow:
11cm = x
2cm = 1 day
[tex]2x = 11 * 1\\2x = 11\\x = 11/2\\x = 5.5 days\\[/tex]
Since it will take 5.5days for 11 cm plant tall to grow, to calculate the number of days 'd' it will take a 65cm plant tall to grow, we can say:
11cm = 5.5days
65cm = "d"
Cross multiply
[tex]11d = 5.5 \times 65\\d = \frac{5.5\times 65}{11}\\[/tex]
Hence the required equation that can be solved to find the number of days, d, it will take for the plant to be 65 cm tall is d= [tex]\frac{5.5\times 65}{11}\\[/tex]

In one problem, he gave her a store receipt that listed 72 identical items, each the
same price, for a total cost of
$ * 67.9*
Bryn's Grandpa covered the first and last digits of the total price on the receipt
with stars.
Determine the values of the digits that Bryn's Grandpa covered.
Answer:
The first covered digit = x = 3
The last covered digit = y = 2
The total price on the receipt = $367.92
Step-by-step explanation:
Given data:
total cost = $ * 67.9*
First we check for the multiples of 72
9 × 8 = 72
Let
the first covered digit be denoted by x
the last covered digit be denoted by y
Solution
First we find the last covered digit
If a number should be divisible by 8,
It must be a multiple of 8
From the given price:
The last 3 digits = 79*
number in multiples of 8
7.9* = 7.20 + 0.64+ 0.08
7.9* = 7.92
Therefore, the last two digit is 2.
Next We find the first covered digit.
If a number is divisible by 9, it is a multiple of 9
The first digit = x would be determined as:
= x + 6 + 7 + 9 + 2
= x + 24
= x + 24
multiple of 9 nearer to 24 = 27
27 = x + 24
x = 27 - 24
x = 3.

The 7 a.m. flight from Dallas to Chicago is on time 75% of the time. Fran created this spinner to simulate the scenario. A spinner with 4 equal sections. 3 sections are shaded. Fran spun the spinner three times to predict whether the flight will be on time or late next Monday, Tuesday, and Wednesday. How should she interpret this outcome of the three spins: shaded-shaded-unshaded? The flight will be late all three days. The flight will be on time all three days. The flight will be late on one of the three days. The flight will be on time on one of the three days.
Answer:
CORRECT OPTION is (C) The flight will be late on one of the three days.
Step-by-step explanation:
The 7am flight from Dallas to Chicago is on time 75% of the time.
A spinner with four sections was created by Fran to simulate this scenario.
Since the 4 sections were equal, it means each section was 25% of the spinner.
3 sections were shaded. That implies 25 × 3 = 75% of the spinner was shaded area.
This coincides with the 75% probability that the flight is on time on a given day.
In other words, if the spinner's pointer lands on shaded area, the flight will be on time. If the pointer lands on an unshaded portion, the flight will be late.
Now Fran spun the spinner 3 times so she has 3 outcomes. The outcomes are:
- Shaded - Shaded - Unshaded
CORRECT OPTION is (C) The flight will be late on one of the three days.
Answer:
C

In the above-given set, there are 8 elements and 12 possible outcomes so, the equation is:

[tex]= \frac{2}{3}[/tex]
by using the general addition Rule:
[tex]\to P(F \cup G) = P(F) +P(G)- P(F \cap G)[/tex]
[tex]=\frac{5}{12}+\frac{4}{12}- P(E \cap H)\\\\=\frac{6}{12}+\frac{3}{12}- \frac{1}{12}\\\\=\frac{6+3-1}{12}\\\\=\frac{8}{12}\\\\=\frac{2}{3}\\\\[/tex]

When the output value of a real-valued function, f(x), is equal to f(-x), for all values of x inside the domain of f, the function is said to be an even function.
It is claimed that a real-valued function f(x) is an odd function when, for all values of x in the domain of f, the output value of f(-x) is equal to the negative of f(x).
Given:
As, we know the first graph graph of an odd function is at the same distance from the origin but in opposite directions and, graph of an even function remains the same after reflection about the y-axis.
So, The polynomial function for this graph is of odd degree and the leading coefficient is negative.
and, The polynomial function for this graph is of even degree and the leading coefficient is negative.

At Henry's yearly physical, he measured 5 feet 8 inches tall. If there are 2.54 centimeters in 1 inch, what is Henry's height in centimeters?
Answer:
172.72 centimeters
Step-by-step explanation:
1. 5 ft. = 60 in.
2. 60 in. + 8 in. = 68 in.
3. 68 x 2.54 = 172.72
4. add unit of measurement to your answer
Henry's height in centimeters is 172.72 cm
What is unitary method ?"A process of finding the value of a single unit, and based on this value we can find the required value. "
For given question,
Henry measured 5 feet 8 inches tall.
There are 2.54 centimeters in 1 inch.
that is, 1 inch = 2.54 cm
First we convert Henry's height in inches.
We know that 1 feet = 12 inches
⇒ 5 feet = 60 inches
so, Henry's height in inches would be,
5 feet 8 inches
= (60 + 8) inches
= 68 inches
From given, 1 inch = 2.54 cm
⇒ 68 inches = 172.72 cm
Therefore, Henry's height in centimeters is 172.72 cm

Is the relationship between the number of tickets sold and the number of hours proportional? If so, how many tickets were sold in 8 hours?
Answer:
640 tickets.
Step-by-step explanation:
8hours × 80 = 640
There are 640 tickets are sold in 8 hours.
What is Proportional?
The equality between two ratio is called Proportional.
Given that;
Number of hours for selling number of tickets.
Since, To check the relationship is proportional or not, we check the equality between two given ratio.
Hence, The ratio are;
Number of hours : Number of Tickets
= 3 : 240 : : 5 : 400
It can be solve as;
= 3/240 = 5/400
= 1/80 = 1/80
= 1:80 : : 1:80
Thus, The given relationship between the number of tickets sold and the number of hours is proportional.
Now, Let number of tickets in 8 hours = x
Then, By definition of proportional we get;
⇒ 3 : 240 :: 8 : x
Solve the proportional as;
⇒ 3/240 = 8/x
⇒ x = 8 × 80
⇒ x = 640
So, There are 640 tickets are sold in 8 hours.
