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

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)
I hope this helps!

A window has an actual height of 4.5 feet. If a blue print has a scale of 3 inches = 2 feet. Find the height of the window in the blue print.
Answer:
The height of the window in blue print 6.75 inches.
Step-by-step explanation:
Given that, the actual length of the window is 4.5 feet.
If a blue print has a scale of 3 inches = 2 feet.
The actual length of an object is 2 feet then length of the object in blue print is 3 inches.
Then the actual length of an object is 1 feet then length of the object in blue print is (3÷2) inches =1.5 inches
The height of the window in blue print = (4.5×1.5)= 6.75 inches.
Answer:
6.75 inches

Jordan and Carson go to the movie theater and purchase refreshments for their friends.
Jordan spends a total of $25.75 on 1 bag of popcorn and 3 drinks.
Carson spends a total of $81.25 on 4 bags of popcorn and 9 drinks.
Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink.
Using these equations, determine and state the price of a drink, to the nearest cent.
Answer:
$7.25
Step-by-step explanation:
Let p=popcorn
Let d=drinks
25.75=1p+3d
81.25=4p+9d
p=4
d=7.25
Answer:
$7.25
Step-by-step explanation:
Cost of popcorn: x
Cost of drink: y
x + 3y = 25.75
x = 25.75 - 3y
4x + 9y = 81.25
4(25.75 - 3y) + 9y = 81.25
103 - 12y + 9y = 81.25
3y = 103 - 81.25
3y = 21.75
y = 7.25
x = 25.75 - 3(7.25)
x = 4

Evaluate without calculator: 167^2−167·67
Answer: 16700
Step-by-step explanation:
First, we must factor 167^2-167*67
Factoring out 167 gives:
167(167-1*67)
Following Order of Operations, you get 167(167-67) which then gets 167(100)
Then, multiply and get 16700
A sample contains 10 pairs of values. Find the critical value for the linear correlation coefficient from Table A-6 corresponding to a 0.01 significance level.
a. 0.684
b. 0.632
c. 0.765
d. 0.798
The closest options provided are c. 0.765 or d. 0.798.
The question involves determining the critical value for the linear correlation coefficient for a sample with 10 pairs of values at a 0.01 significance level. Since the sample size is 10, the degrees of freedom (df) would be calculated as n - 2, which equals 8 (10 - 2 = 8). According to the provided studies and tables of critical values for determining the significance of a correlation coefficient, we reference a critical values table specific to our degrees of freedom and significance level.
At a 0.01 significance level and with 8 degrees of freedom, the corresponding critical value would typically be found in a statistical table designed for this purpose. However, based on the example given in the context, which is using a table with a standard significance level of α = 0.05, we can infer that the critical value for α = 0.01 would be higher, as the significance level is more stringent. None of the provided options (a. 0.684, b. 0.632, c. 0.765, d. 0.798) directly match the information given, but option c. 0.765 or d. 0.798 would typically be closer to a critical value at an α = 0.01 level with 8 degrees of freedom.

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]

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.

Use the inequality to express the statement in symbols. The population (P) varied from 1000 to 15000 in the rural towns.
PLEASE HELP ME IM IN A FINAL!!!!
Answer:
[tex]1000\leq P\leq 15000[/tex].
Step-by-step explanation:
It is given that the population (P) varied from 1000 to 15000 in the rural towns.
We need to write an inequality which express the statement in symbols.
Variable P represents the population of rural towns.
Since population varied from 1000 to 15000, therefore the value of P must be greater than or equal to 1000 and less than or equal to 15000.
It can be written as
[tex]1000\leq P\leq 15000[/tex]
Therefore, the required inequality is [tex]1000\leq P\leq 15000[/tex].
