Answer:

24°

Step-by-step explanation: a flat surface=180° 180-156=24

Answer:

24 °

Step-by-step explanation:

Supplementary angles are two angles that add up to 180°

One angle is 156 so 180-156 gives you the angle of the missing angle. The answer of 180-156 is 24 so therefore, x=24°

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)

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.

Answer:

52 Blocks

Step-by-step explanation:

We need to find how many blocks Mona walks per day.

Info Given:

Number of blocks she walks in one walk.

Add the total blocks in one "route".

[tex]5 + 2 = 7\\7 + 6 = 13[/tex]

Mona walks 13 blocks in one route.

She walks her dog 4 times a day.

[tex]13 * 4 = 52[/tex]

Mona would walk her dog 52 blocks total per day.

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 :)

Answer: D, It is a function because there is only one y value for every x value.

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.

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

The unknown number is: 21

Step-by-step explanation:

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

Answer:

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 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.

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
