Answer:
Percent error is 44.4%
Step-by-step explanation:
Here, we want to get the percent error
From the question, prediction is 54 while actual value is 78
from the formula given;
Percent error = |prediction-actual|/actual * 100%
so we have
|54-78|/54 * 100%
= 24/54 * 100% = 44.4%
convert 0,6 to percentage
Answer:
6/10 is the percentage form of 0.6
Answer:
0,6 to a percentage is 60%.

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.

A cyclist rides his bike at a speed of 27 miles per hour what is the speed in miles per minute? How many miles will the cyclist travel in 2 minutes ? Do not round answer
Answer:
The cyclist can travel 0.9 miles in 2 minutes.
Step-by-step explanation:
1 hour = 60 minutes
Set up a conversion equation:
27 mi/1 hr × 1hr/60 mins
It is easier to see when writing it on paper, but the fractions are set up in a way to cancel the units out until the only units left are miles and minutes
After multiplying the numerators together and then multiplying the denominators together, you should reach the answer:
27 mi/60 mins
The cyclist can travel 27 miles in 60 minutes, but how many miles can he travel in 2 minutes?
Set up an equation:
Variable x = number of miles
27 mi/60 mins = x/2 mins
Cross multiply
27 × 2 = 60 × x
54 = 60x
Divide both sides by 60
0.9 = x

Find the missing dimension. Use the scale factor 1 : 12.
Answer:
3.84m
Step-by-step explanation:
If the scale for this Water tower is 1 : 12 then this means that for every 1cm of the model, the actual water tower has 12cm. Therefore, in order to find the actual depth of the water tower we first need to multiply the depth of the model by 12.
32cm * 12 = 384cm
1 cm is equal to 0.01 m , therefore we now have to multiply the depth of the actual water tower which is in cm by 0.01 to get the actual depth in meters
384 * 0.01 = 3.84m

math question:
simon believes that 3^0 • 3^2 is equal to 1 because 0 • 2 = 0 and any number raised to a power of 0 is 1. Is Simon correct? Justify your response.
Answer:
Simon is incorrect
Step-by-step explanation:
3^0 is not 0, it is 1.
A way of thinking about this is if to get from 3^2 to 3^1, you need to divide by 3, then to get from 3^1 to 3^0 you need to divide by 3 again. 3 divided by 3 is 1.
This means 3^0*3^2=1*9=9

A right cylinder has a height of 8 inches and a volume of 100 cubic inches. Which measurement is closest to the radius, in inches, of the cylinder? B. C. 16 D. 50
Answer:
A
Step-by-step explanation:
volume of a cylinder:
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
We are given the volume (V) and the height (h) and we need to find the radius (r).
To find the radius we are going to want to plug in the given values into the formula for volume of a cylinder and solve for r
so, * plug in given values *
[tex]400= \pi r^28[/tex]
Now we solve for r
step 1 take the square root of each side
[tex]\sqrt{400} =20\\\sqrt{\pi r^28} =\sqrt{\pi } 4*r\\[/tex]
now we have [tex]20=\sqrt{\pi } 4*r[/tex]
step 2 divide each side by sqrt (π) 4
[tex]\frac{20}{\sqrt{\pi } 4} =3.989 \\\\\frac{\sqrt{\pi } 4*r}{\sqrt{\pi } 4}=r\\[/tex]
we're left with r = 3.989
Finally we round to the nearest whole number and get that the answer is A.4
Prove quadrilateral MATH, M (-4,-1) A(-3,2). T(3, 0), H(2, -3) is a rectangle
Answer:
Quadrilateral MATH is a rectangle
Step-by-step explanation:
Prove quadrilateral MATH, M (-4,-1) A(-3,2). T(3, 0), H(2, -3) is a rectangle
A rectangle is a quadrilateral whose opposite sides have the same lengths and are parallel.
We solve the above question using the formula below to find the length of its sides
= √(x2 - x1)² + (y2 - y1)² when we are given vertices(x1, y1) and (x2, y2)
For side MA
M (-4,-1) A(-3,2)
√(-3 - (-4))² + (2 - (-1))²
= √1² + 3²
= √1 + 9
= √10 units
For side AT
A(-3,2). T(3, 0)
√(3 - (-3))² + (0 - 2)²
= √6² + -2²
= √36 + 4
= √ 40 units
For side TH
T(3, 0), H(2, -3)
√(2 - 3)² + (-3 - 0)²
√-1² + -3²
= √1 + 9
= √10 units
For side MH
M (-4,-1) H(2, -3)
√(2 - (-4))² + (-3 - (-1))²
= √6² + 2²
= √36 + 4
= √40 units
From the above calculation, we can see that
Side MA = Side TH = √10 units
Side AT = Side MH = √40 units
Opposite sides are parallel to each other, hence quadrilateral MATH is a rectangle

The minimum is the lowest number in the data set.
Since it is listed from smallest to largest, we know that the minimum is
29
.
The median is the middle number. Cancel out
3
numbers from each side and we are left with the median:
29
,
33
,
36
,
37
,
39
,
40
,
41
Therefore, the median is
37
.
The first quartile (Q1) is the median of the lower half of data which lies at 25% of the data.
Let's look at the lower half of numbers:
29
,
33
,
36
The number in the middle is
33
, so that is the first quartile.
The third quartile (Q3) is the median of the upper half of data which lies at 75% of the data.
Let's look at the upper half of numbers:
39
,
40
,
41
The number in the middle is
40
, so that is the third quartile.
The maximum is the highest number in the data set; it is
41
.
So here's the five-number summary:
Minimum: 29
First quartile: 33
Median: 37
Third quartile: 40
Maximum: 41

You start at (9, 5). You move right 1 unit. Where do you end? y x 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 0 ( , )
Answer:
(10, 5)
Step-by-step explanation:
Starting coordinate : (9, 5)
x = 9 ; y = 5
Vertical distance (up and down) = y
Horizontal distance (left and right) = x
Movement to the right = positive
Movement to the left = negative
Hence, 1 unit moved to the right ; x + 1
Therefore ;
(9 + 1, 5)
= (10, 5)
