which is it ppl?i need this

Answer:

36degrees

Step-by-step explanation:

2x + 26 = 3x + 21

2x - 3x = 21 - 26

-x = -5

x = 5

m<B = (3x+21)°

m<B = 3(5) + 21

m<B = 15+21

m<B = 36degrees

Answer:

1

Step-by-step explanation:

Hello!

We can solve this by using the Difference of Squares formula:

47² - 46², the numerator, is very similar to a² - b², so we can extract 47 as a, and 46 as b.

Rewrite the numerator:

We can use the same formula for the denominator the same way:

Rewrite the fraction and simplify:

The answer is 1.

Answer:

2.2

Step-by-step explanation:

If you find the mean of the deviation, you get 2.2

The mean absolute deviation of the data is M = 2.2

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the total number of points be n

Now , the value of n = 10

And , the number of points on each data is given by set A

Now , the value of set A = { 7 , 2 , 8 , 5 , 9 , 9 , 5 , 6 , 8 , 1 }

So , the total sum of data = 7 + 2 + 8 + 5 + 9 + 9 + 5 + 6 + 8 + 1

The total sum of data = 60

Now , the mean number of data points = 60/10 = 6

And , the mean deviation is M

M = 1/10 | [ ( 7  - 6 ) + ( 2 - 6 ) + ( 8 - 6 ) + ( 5 - 6 ) + | ( 9 - 6 ) | + ( 9 - 6 ) + ( 5 - 6 ) + ( 6 - 6 ) + ( 8 - 6 ) + ( 1 - 6 ) |

M = ( 1/10 ) [ 1 + 4 + 2 + 1 + 3 + 3 + 1 + 0 + 2 + 5 ]

M = ( 1/10 ) [ 22 ]

M = 2.2

Therefore , the value of M is 2.2

Hence , the mean deviation is 2.2

Answer: it is a statistical question

Step-by-step explanation:

Answer:

read the explanation.

Step-by-step explanation:

Part A:

I would expect her to collect a certain number of times, such as: each dot = 1 hour. For example, if she had a dot plot or a chart to divide how much time each student stays at the beach (if that is understandable), along with her collecting the students' names to figure out the answer to her question.

Part B:

This is definitely a statistical question.

A statistical question is a question that can be solved by collecting data that varies.

so this can definitely be solved by collecting data. To even solve this, you need to collect data. The easiest way to solve this is with a dot plot. In my opinion, you also need to gather the students data, such as their names and how many (for example) hours at the beach they spent time there.

Answer:

204.2     square cm

Step-by-step explanation:

Area of the whole circle

PI x 9 squared =

PI x 81 = 254.4690...

Area whire circle

PI x 4 squared=

PI x 16 = 50.2654

        Subtract white circle from the whole circle

254.4654 - 50.2654 = 204.2035...

The required area of the two concentric circles is given as 204.20 square cm.

Given that,
The shaded area of the figure shown, correct to one decimal place is to be determined.

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
According to the question,
Area of the shaded area = 3.14 [9]²- 3.14[4]²
Area of the shaded area = 204.20 square.

Step-by-step explanation:

Answer:

the answer in the image is Y

Step-by-step explanation:

[tex]0.4 \div 0.2 = 2 \\✓ = option \: 3[/tex]

Answer:

The model that correctly shows the problem 0.4 divided by 0.2 is option 3.

Step-by-step explanation:

Option 3 has 4 out of 10 rowS shaded in, which you can infer immediately is the correct answer. Since 10 rows represent 1 whole, that means that 4 rows shaded in are 0.4. In option 3, the four rows are split by blue lines and have 2 rows, or 0.2, in each group, so option 3 matches the problem 0.4 divided by 0.2.

7. adjacent

8.127°

Step-by-step explanation:

adjacent angles on a straight line add up to 180°

180-53=127°

Answer:

they are supplementary

x = 127

Step-by-step explanation:

supplementary angles equal 180 degrees so you would do: 180 - 53 to find x

Answer:

B. is the correct answer.

Thank you.

Step-by-step explanation:

Answer:

r2 means r x r

Step-by-step explanation:

2 is an exponent, meaning that the number (what r is) will multiply twice, meaning r x r.

For example, if r was 4, then you would multiply 4 x 4, which is 16 and not 4 x 2, which is 8.

Many make this mistake, which can cause big trouble. As you saw in the example above, products are not the same.

Answer:

x≥−3

Step-by-step explanation:

Let's solve your inequality step-by-step.

−4x−10≤2

Step 1: Add 10 to both sides.

−4x−10+10≤2+10

−4x≤12

Step 2: Divide both sides by -4.

−4x /−4 ≤ 12 /−4

= x≥−3

Answer:

x ≥ -3

Step-by-step explanation:

you add 10 on both sides

-4x - 10 ≤ 2

      +10  +10

=   -4x ≤ 12

then you divide -4 on both sides to get the x by itself

12/-4 is -3

since you divided by a negative you flip the sign

Answer:  Hello, There! your Answer is Below

40 Is your Answer

Step-by-step explanation:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with XStep 3:

From step 1 above,$80=100

Step 4: Similarly, x=50

Step 5: This results in a pair of simple equations:This results in a pair of simple equations:

$80=100\(1)

$x=50(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

80/x = 100%/50%

Step 7: Again, the reciprocal of both sides gives

x/80 = 50/100

x=40$

Therefore, 50%of 80i s 40

Answer:

Take the square root of each side

D (x+b/2a)  =±sqrt( (b^2-4ac)/ 4a^2)

Step-by-step explanation:

We have

(x+b/2a) ^2 = (b^2-4ac)/ 4a^2

We need to take the square root of each side to continue to isolate x

(x+b/2a)  =±sqrt( (b^2-4ac)/ 4a^2)
