Answer:
1
Step-by-step explanation:
Hello!
We can solve this by using the Difference of Squares formula:
(a + b)(a - b) = a² - b²47² - 46², the numerator, is very similar to a² - b², so we can extract 47 as a, and 46 as b.
Rewrite the numerator:
47² - 46²(47 + 46)(47 - 46)(93)(1)93We can use the same formula for the denominator the same way:
17² - 14²(17 + 14)(17 - 14)(31)(3)93Rewrite the fraction and simplify:
[tex]\frac{93}{93}[/tex][tex]\frac11[/tex]1The answer is 1.

The perimeter of a rectangular picnic area is 590 yards. It is 100 yards wide. How long is it?
Answer:
195
Step-by-step explan
Answer:
195 yards
Step-by-step explanation:
remember a rectangle has 4 sides.
100 yards wide is how wide 1 side is. so 2 sides are 200 yards wide.
to determine the width you subtract 200 yards from 590 which give you the answer 390. finally to determine just one side of the length you need to divide 390 in two to get 195 yards.

Answer:
[tex]6\pi[/tex] inches
Step-by-step explanation:
The area of a circle is [tex]\pi r^2[/tex].
Since [tex]\pi r^2=9\pi[/tex]
[tex]r^2=9[/tex]
And
[tex]r=3[/tex]
Since the radius is 3 inches,
the diameter would then be 6 inches. (3 * 2)
The circumference of a circle is [tex]\pi d[/tex], d being the diameter.
Hence, the circumference is [tex]6\pi.[/tex]

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

There are 80 students in the sixth grade at Baker Street School, and 50% of thern take notes with a pencil sixth-grade students who take notes with a pencil.
how many sixth grade students take notes with a pencil?
I think the answer would be 40
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

Find the shaded area of the figure shown, correct to one decimal place. Use the pi button on your calculator for pi in your calculations.
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.
Thus, the required area of the two concentric circles is given as 204.20 square cm.

Using the following data, calculate the mean absolute deviation:
7 2 8 5 9 9 5 6 8 1
What is the mean absolute deviation for these data?
2.2
6
6.5
8
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
What is Mean?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

The Lunchroom Murder
On an otherwise uneventful Thursday afternoon police heard a shot inside the local bistro, Ernie’s Lunchroom. They rushed in and found the scene shown in Figure 1.4.
They identified the body as that of a prominent racketeer named Fannin. Ernie, who is both the owner and only employee, had only one fact to tell: the murderer had leaned against the wall while firing at point-blank range. The imprint of his hand is in clear view.
The police have also noticed that the cash register had just been rung up at $8.75.
This is a difficult case. Your investigative team must attempt to determine which of the people in the lunchroom killed Fannin. You will have to observe the details carefully. There is enough evidence to help you explain most of what happened.
QUESTION: Which set of footprints are Ernie’s? What is the evidence?

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

What is the solution set for -4x-10 ≤ 2?
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
brainliest please?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
