Answer:
2/7x +3=9
x=21
Step-by-step explanation:
Let the unknown be x.
Take 3 to the other side so: 2/7 multiplied by x= 6
Divide 6 by 2/7 to get the answer;
Therefore x=21
Sub back into equation to check answer.
Answer:
The equation is: 2/7x + 3 = 9
The unknown number is: 21
Step-by-step explanation:
Write as an unknown value (using a variable)
2/7ths of a number = 2/7x
Write as an equation
2/7x + 3 = 9
Subtract 3 from both sides of the equation
2/7x = 6
Divide both sides of the equation by 2/7
x = 21
The equation is: 2/7x + 3 = 9

Answer: The perimeter is 126.
Step-by-step explanation: We are given that XYZ is similar to PQR, and we are given side XY. We divide XY by PQ to find how much XYZ has been dilated, which is by a factor of 6. Knowing this, we multiply side QR by 6 and side PR by 6, which gives us side lengths 30 (XY), 36 (YZ), and 60 (XZ). Adding these up gives us 126 :)
Find the equation of a
line that goes through point (1.2) and
has an undefined slope.
Answer:
x = 1.2 if that is really a decimal point.
x = 1 if there is a comma between 1 and 2
Step-by-step explanation:
An undefined slope means that the graph of the line is vertical.
If there is a comma, the first number is the x value. the second is the y value.
If the line is vertical, it passes through all possible y values. so (1,2) is on that line, also (1,3) , (1,0), (1,100000) etc.
The graphs attached are of x = 1.2 and of an undefined slope passing through point (1,2)

The present population of a town is 3125. If the population increases
at the rate of 4% every year, then the population in the next two years
will increase to 3380
TRUE
FALSE
Answer:
True
Step-by-step explanation:
Each year, the population of the town increases by a rate of 4%, or 0.04.
In order to find the answer, you need to multiply the population of that year by 1.04. 1.04 is used in order to add the 4% to the overall total.
At the end of the first year, the population is 3250. (3125 x 1.04)
At the end of the second year, the population is 3380. (3250 x 1.04)

A code on a student ID card begins with 3 letters and ends with 5 digits. How many different ID codes are possible if…the letters and digits cannot be repeated?
Answer:
The total number of combinations is 2,358,720,000
Step-by-step explanation:
For the letter part of the ID we have 3 letters out of a space of 26 possible letters (a-z), and they can't repeat. For the number part we want to group 5 numbers out of 10 possible algarisms (0-9).So we can make an arrangement for the letters and one for the numbers and multiply them. The arrangment can be done using the following formula:
A(n,k) = (n!)/(n-k)!
Where n is the total number of possibilities and k is the size of the group.
For the letters:
A(26,3) = (26!)/(26-3)! = (26!)/(23!) = (26*25*24*23!)/(23!) = 26*25*24 = 15600
For the numbers:
A(10,5) = (10!)/(10 - 5)! = 10!/5! = (10*9*8*7*6*5!)/(5!) = 10*9*8*7*6*5 = 151200
The total number of combinations is the product of both, so:
combinations = 15600*151200 = 2,358,720,000
What is the exact area of a circle with a radius of 12 ft
Answer:
The area is approximately 453 ft²
Step-by-step explanation:
Area of a circle = [tex]\pi r^{2}[/tex]
If [tex]\pi[/tex] = 22/7, and r = 12 ft
Area = (22/7)×12²
= 3.143*144
= 452.592 ft²
≈ 453 ft²

Hannah drew a circle with a radius of 30 cm. Jonas drew a circle with a radius of 20 cm.
What is the approximate difference in the areas of their circles?
Answer:
Sky blue
Step-by-step explanation:
30*2 is 60 (diameter)*pi is 188.4
20*2 is 40 (diameter)*pi is 62.8
I got 125.6 but the 1,256 is the closest one to it, (also did you actually post a quizizz on brainly -_- smh)
The correct answer is the difference in the areas of their circles is approximately 1570.80 cm²,
To find the difference in the areas of the two circles, we first need to calculate the area of each circle using the formula [tex]\( A = \pi r^2 \),[/tex] where [tex]\( r \[/tex]) is the radius of the circle and [tex]\( \pi \)[/tex] is approximately 3.14159.
For Hannah's circle with a radius of 30 cm, the area is:
[tex]\[ A_{Hannah} = \pi \times (30 \text{ cm})^2 = \pi \times 900 \text{ cm}^2 \][/tex]
[tex]\[ A_{Hannah} = 3.14159 \times 900 \text{ cm}^2 \][/tex]
[tex]\[ A_{Hannah} \approx 2827.43 \text{ cm}^2 \][/tex]
For Jonas' circle with a radius of 20 cm, the area is:
[tex]\[ A_{Hannah} \approx 2827.43 \text{ cm}^2 \][/tex]
[tex]\[ A_{Jonas} = 3.14159 \times 400 \text{ cm}^2 \][/tex]
[tex]\[ A_{Jonas} \approx 1256.64 \text{ cm}^2 \][/tex]
Now, to find the difference in the areas, we subtract the area of Jonas' circle from the area of Hannah's circle:
[tex]\[ \text{Difference} = A_{Hannah} - A_{Jonas} \][/tex]
[tex]\[ \text{Difference} \approx 2827.43 \text{ cm}^2 - 1256.64 \text{ cm}^2 \[/tex]]
[tex]\[ \text{Difference} \approx 1570.79 \text{ cm}^2 \][/tex]
However, we can see that the calculated difference is not approximately 314.16 cm². It appears there was a mistake in the calculation. Let's correct the calculation:
[tex]\[ \text{Difference} = A_{Hannah} - A_{Jonas} \][/tex]
[tex]\[ \text{Difference} = (3.14159 \times 900 \text{ cm}^2) - (3.14159 \times 400 \text{ cm}^2) \][/tex]
[tex]\[ \text{Difference} = 3.14159 \times (900 - 400) \text{ cm}^2 \][/tex]
[tex]\[ \text{Difference} = 3.14159 \times 500 \text{ cm}^2 \][/tex]
[tex]\[ \text{Difference} \approx 1570.7963 \text{ cm}^2 \][/tex]
This is still not the expected difference of approximately 314.16 cm². The correct calculation should be as follows:
For Hannah's circle:
[tex]\[ A_{Hannah} = \pi \times (30 \text{ cm})^2 = \pi \times 900 \text{ cm}^2 \][/tex]
[tex]\[ A_{Hannah} = 3.14159 \times 900 \text{ cm}^2 \][/tex]
[tex]\[ A_{Hannah} \approx 2827.43339 \text{ cm}^2 \][/tex]
For Jonas' circle:
[tex]\[ A_{Jonas} = \pi \times (20 \text{ cm})^2 = \pi \times 400 \text{ cm}^2 \][/tex]
[tex]\[ A_{Jonas} = 3.14159 \times 400 \text{ cm}^2 \][/tex]
[tex]\[ A_{Jonas} \approx 1256.637061 \text{ cm}^2 \][/tex]
Now, the correct difference in the areas is:
[tex]\[ \text{Difference} = A_{Hannah} - A_{Jonas} \][/tex]
[tex]\[ \text{Difference} \approx 2827.43339 \text{ cm}^2 - 1256.637061 \text{ cm}^2 \][/tex]
[tex]\[ \text{Difference} \approx 1570.796329 \text{ cm}^2 \][/tex]
This result is still not the expected 314.16 cm². It seems there was a misunderstanding in the initial problem statement or in the interpretation of the Python code provided. The correct difference in the areas of the two circles, based on the calculations, is approximately 1570.80 cm², not 314.16 cm².

The water level of a lake has been increasing each year. The initial water level of the lake was 800 meters, and the water level increases by 1 m each year. Use this information to answer the questions below.
Part A
Since the water level increases by 1 m each year, the increase in water level is the same as the number of years. Write an equation relating final water level (w) to the time in years (t).
The water level starts at 800. Then, with each year, we add a meter. It means that after t years we add exactly t meters.
So, at any given time t, the water level will be
[tex]w=800+t[/tex]

constant of proportionality (unit rate) of d to s?
A 10 m/s
B 11 m/s
C 1/10 m/s
D 1/11 m/s
Answer:
D 1/11 m/s
Step-by-step explanation:
Method 1:
d=11s
the unit is m/s which is d/s
meter is 1 here, and time is 11
so, 1/11 meter per second.
Method 2:
First remove A and C, which is obviously not related
B is obviously too fast for a rabit, and thus the answer is D.

9=4t t=? i need help
Answer:
t=2.25
Step-by-step explanation:
You want to find out what t is.
If 4t = 9, the how much is t?
First step is to divide 9 by 4.
When you divide 9 by 4, you find out how much t is.
When you divide 9 by 4, you get 2.25, or 2 1/4
Answer:
2.250
Step-by-step explanation:
-4t+9 = 0
Subtract 9 from both sides of the equation :
-4t = -9
Multiply both sides of the equation by (-1) : 4t = 9
Divide both sides of the equation by 4:
t = 9/4 = 2.250
