The error interval for the area is 64.2< a < 63.93
What is error interval?Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.
Given:
Area of circle = 76.9 cm²
Area of square = 12.7 cm²
Now, 1 decimal point
Area of circle,
= 76.9+0.05 and = 76.9-0.05
= 76.95 and = 76.85
Area of square,
= 12.7-0.05 and = 12.7+-0.05
=12.65 and = 12.75
Area of shaded region in the form m < a < n .
m= 76.95-12.75
m= 64.2
n= 76.85-12.65
n= 63.93
Area of shaded region is 64.2< a < 63.93.

What is the slope of the line that passes through the points (-6,8) and (-16,33)
Answer:
-5/2 or -2.5
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
(y2 - y1) / (x2 - x1)
(33 - 8) / (-16 + 6)
25 / -10
= -5/2
So, the slope is -5/2 or -2.5
Answer:
Solution :-We know that
Slope

Where
y2 = 33
y1 = 8
x2 = -16

The scatter plot shows the average movie ticket prices since 1995.
write an equation in slope intercept form for the line that is drawn
use your equation to make a conjecture about the average cost of a movie ticket in 2020
Answer:
The average movie ticket prices in 2020 was $ 10.25.
Step-by-step explanation:
If (0 , 4) and ( 8, 6) are two points on a line, the slope of the line is:
m= y2 - y1/ x2 - x1
m= (6 - 4) / (8 - 0)
m= 1 / 4
The y-intercept is $ 4, meaning it is the average movie ticket price in 1995.
Therefore,
Y = mx + b
Y = 1/4 x + b
It is m= 1/4, interpreting the slope we have that for every additional 4 years the average movie ticket price will increase by $ 1.
The year 2020 is 25 years after 1995, then
Y= 1/4 (25) + 4
Y = $ 10.25
The average movie ticket price was $10.25 in 2020.

Sodas cost $1.50 and a cup of coffee costs $1.25 at a football game. Sally
bought 8 drinks total for all of her friends and her total cost was $11.50. How
many of each drink did she buy?
Answer:
the answer 4
Step-by-step explanation:
4 of each because (1.25x4) + (1.50x4) = 11.50
Answer:
Sally bought 6 sodas and 2 cups of coffee.
Step-by-step explanation:
Variable x = number of sodas
Variable y = number of coffees
$1.50x + $1.25y = $11.50
x + y = 8 drinks
$1.50(6) + $1.25(2) = $11.50
$9.00 + $2.50 = $11.50
I simply plugged in numbers that totalled to 8 drinks until I reached $11.50 as the total.
For example:
$1.50(5) + $1.25(3) = $11.50
$7.50 + $3.75 = $11.50
$11.25 = $11.50
This is not correct as they do not equal so this cannot be the answer.

Which of the following statements represents a correct relationship?
a.) 345 > 354
b.) 400 < 40
c.) 4,008 < 4,080
d.) 23,090 = 23,009
Answer:
I think C
so it's kind of a process of elimination you have to see the order of the numbers and what order each number is in so for A you can see that it's 345 is greater than 354 which is inspect cuz 354 is greater than 345 for B that's an obvious answer is is 400 is less than 40 which is obviously wrong because 400 is greater has two zeros and 40 only has one 0 for C it has 4008 is less than 4080which is actually correct if you look at the way that the numbers are written you could see that 80 is greater than 8 D it's obviously not correct because it says 20090 is equal to 23009 which is incorrect because 90 is greater than 9

11y = 165
y = 15
m<A = 4y + 14 = 4(15) + 14 = 74°

What is the slope and y-intercept of the line?
Answer:
Slope = 3
Y-intercept = -2
Step-by-step explanation:
Points on the line: (0, -2) and (1,1)
Slope:
m=(y2-y1)/(x2-x1)
m=(1+2)/(1-0)
m= 3/1
m = 3
Slope-intercept:
y - y1 = m(x - x1)
y + 2 = 3(x - 0)
y + 2 = 3x
y = 3x - 2
y = mx + b, where
m = slope
b = y-intercept

A regular hexagonal prism has an edge length 11 cm, and height 8 cm. Identify the volume of the prism to the nearest tenth.
Answer:
it may be V ≈ 4191.6 cm3 so sorry if i'm wrong!!!
Step-by-step explanation:
Answer: V ≈ 2514.9 cm3
Step-by-step explanation:
To find the volume of the prism, first calculate the area of the base.
To find the apothem of the hexagonal base, recognize that the sum of the measures of the interior angles in a hexagon is (6−2)⋅180°=720°. So, the interior angle has measure 720°6/=120°.
The base angle of the triangles with the hexagon's sides as their base is one-half of 120°, or 60°. The apothem bisects these triangles to form two right triangles with the short leg length of 5.5 cm.
By the definition of tangent, tan 60°=?/5.5.
Solve for ?.
?=5.5 ⋅ tan 60°
Therefore, the apothem length equals 5.5 ⋅ tan 60°.
The area of a hexagonal base.
B=6⋅(12⋅11⋅?)
Substitute 5.5⋅tan60° for ?.
B=6⋅(12⋅11⋅5.5 ⋅ tan60°)
Simplify.
B=181.5 ⋅ tan60° cm2
The volume of a prism.
V=Bh
Substitute 181.5 ⋅ tan60° for B and 8 for h.
V=(181.5 ⋅ tan60°)⋅8
Multiply 181.5 by 8.
V=1452 ⋅ tan60°
Use a calculator to approximate.
V≈2514.9 cm3
Therefore, the volume of the hexagonal prism is approximately 2514.9 cm3.

step 1
step 2
step 3
olga did not make a mistake
Answer:
Step 3
Step-by-step explanation:
Given the equation :
1/4(1/3k+9)=6
Step 1 : Olga multiplied both sides by 4
1/4(1/3k + 9) * 4 = 6* 4
1/3k + 9 = 24
Step 2 : Olga subtracted 9 from sides
1/3k + 9 - 9 = 24 - 9
1/3k = 15
Step 3 : Both sides should be multiplied by 3
1/3k * 3 = 15 * 3
k = 45
This is the step Olga made a mistake. Olga attempted to divide 15/3 = 5 instead of Multiplying 15 * 3 to obtain 45
