Answer:
Hey! Answer: F
Step-by-step explanation:
13.5 ÷ 9= 1.5
18 ÷ 12 = 1.5
So our pattern is to enlarge/multiply it by 1.5
So 1.5 x 15 = 22.5
So F is our answer!
A regular hexagon is inscribed in a circle with a diameter of 8 inches.
a. What is the perimeter of the hexagon?
b. What is the area of the hexagon?
Step by step please!!!
Answer:
b) 41.6 square inches
Step-by-step explanation:
A regular hexagon is inscribed in a circle with a diameter of 8 inches.
Step 1
We find the radius
Radius = Diameter/2
= 8 inches/2 = 4 inches
a. What is the perimeter of the hexagon?
b. What is the area of the hexagon?
An hexagon has 6 sides
The number of angles in an hexagon is calculated as:
[(Number of sides - 2) x 180]
= (6 - 2) x 180 = 720 ÷ 6 = 120°
The hexagon into 6 equilateral triangles with 4 for each of its sides.
The area of one of the triangles:
Height = 2√3
- one triangle's area = (1/2)bh = (1/2)(4)(2√3) = 4√3
The area of the hexagon by multiplying the one triangle's area by 6:
6 x 4√3 = 24√3 square inches
= 41.569219382 square inches
Approximately = 41.6 square inches
Solve for x.........
Answer:
x = 12
Step-by-step explanation:
Angle QPR + Angle PQR = Angle HRQ
[tex]30 + 4x + 2 = 8 + 6x \\ (6 - 4)x = 30 + 2 - 8 \\ 2x = 24 \\ x = 12[/tex]
Answer:
17°
Step-by-step explanation:
30°+8+6x=180 ...angles on a str. line
180-30=150
150÷6=25
25-8=17°
therefore 8+6(17°)
4(17°)+2=70°

[tex]\tan(A - \frac{\pi}{4}) = \frac{-\sqrt{15}- 1}{1 -\sqrt{15}}[/tex]
Step-by-step explanation:
Given
[tex]\tan A =-\sqrt{15[/tex]
Required
Find [tex]\tan(A - \frac{\pi}{4})[/tex]
In trigonometry:
[tex]\tan(A - B) = \frac{\tan A - \tan B}{1 + \tan A \tan B}[/tex]
This gives:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - \tan \frac{\pi}{4}}{1 + \tan A \tan \frac{\pi}{4}}[/tex]
[tex]tan \frac{\pi}{4} = 1[/tex]
So:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A * 1}[/tex]
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A}[/tex]
This gives:
[tex]\tan(A - \frac{\pi}{4}) = \frac{-\sqrt{15}- 1}{1 -\sqrt{15}}[/tex]

Step-by-step explanation:
6^2 because,
6^1 is not a perfect square because 6 is its own number because 6 x 1 =6 Therefore being eliminated.
6^3 is not a perfect square because 6 x 6 x 6 (216) is cubed not square
*This one almost tricked me*
6^5 is not a perfect square because 6 x 6 x 6 x 6 x 6 (7776) it isn't an equal factor combination, that when multiplied together, produce the number 7,776. That means 7,776 is not a perfect square.
6^2 is a perfect square because 6x6= 36 and 36 is a perfect square.
Therefore, its 6^2

even though r5 looks correct, you always have to put the varible on the right side of a number. 2r+3r is correct because if you combine like terms, you get 5r
brass is an alloy of zinc and copper. if 30% of the content is zinc . find the weight of zinc and copper in 300 gram of brass.
Step-by-step explanation:
Here's your solution
=> percentage of zinc = 30%
=> total weight of alloy = 300 gram
=> amount of zinc = (30/100)*300 = 90 gram
=> amount of copper = 300 - 90 = 210 gram

take the derivative of the equation 4 times. f 4 (x)=0.
Step-by-step explanation:
if you put in the values (-1/2, 1/4, 2/5) in the function
{–8, –2, 18}
Step-by-step explanation:
y = 5x − 2
x = −1.2 > y = 5(−1.2) − 2 = −6 − 2 = −8
x = 0 > y = 5(0) − 2 = 0 − 2 = −2
x = 4 > y = 5(4) − 2 = 20 − 2 = 18
{-1/2, 1/4, 2/5}
Step-by-step explanation:
All you have to do is go on a graphic calculator and input the equation by pressing y= then after putting it in to y= all you have to do is press 2nd (the only blue button) and graph and that will show you all the points to that equation (also known as range and domain)
Hope this helps. :)
Domain is inputs, input the domain for x
y=5(-1.2)-2
y=-6-2
y=-8
y=5(0)-2
y=0-2
y=-2
y=5(4)-2
y=20-2
y=18
range is {-8, -2, 18}
For x = 0,
we substitute zero into the equation to find its y value like so:
y = 5x-2
y = 5(0)-2
y = -2
There you go.
Take the derivative of the equation 4 times. f 4 (x)=0.
Y = 5x – 2
domain. {–5, –1, 0, 2, 10}
x = -5 then y = 5(-5) – 2 = -27
x = -1 then y = 5(-1) – 2 = -7
x = 0 then y = 5(0) – 2 = -2
x = 2 then y = 5(2) – 2 = 8
x = 10 then y = 5(10) – 2 = 48
answer
{–27, –7, –2, 8, 48}

What is the total number of digits required in numbering a book that has 1724 pages?
Answer:
5,789
Step-by-step explanation:
I got 5,789 because there are 9 one digit numbers. 1-9 -> 9x1=9. There are 90 two digit numbers. (10-99)-> 90x2=180. There are 900 three digit numbers. (100-999)-> 900x3=2700. There are 725 four digit numbers. (1000-1724)-> 724x4= 2900. Then, I added 9+180+2700+2900=5789.
In conclusion, the total number of digits required in numbering a book that has 1724 pages is 5789.
There are 5,789 digits in total required to number the pages of a book with 1,724 pages.
What is Numbering?A numbering is the assignment of natural numbers to a set of objects in some formal language, such as functions, rational numbers, graphs, or words, in computability theory.
Digits required in numbering a book that has 1724 pages?Given the total number of pages is 1,724
Let's break down the pages now to find the total digits.9
one-digit numbers (1-9) = 9 x 1 = 9 digits make up the number 1,724.90 numbers with two digits (10-99) = 90 x 2 = 180 digits900 three-digit numbers (from 100 to 999) = 900 times three = 2700 digits725 numbers with four digits (1000-1724) = 725 x 4 = 2900 digits
Let's add the digits now.9 + 180 + 2700 + 2900 = 5,789
As a result, the total number of digits required to number the pages of a 1,724-page book is 5,789.

Laura wants to cover a box with fabric.
• The box is in the shape of a rectangular prism.
• It measures 15 in. long, 11 in. wide, and 24 in. tall.
Answer:
Area of rectangular prism = 1,578 inch²
Step-by-step explanation:
Given:
Length of rectangular prism = 15 in
Width of rectangular prism = 11 in
Height of rectangular prism = 24 in
Find:
Total fabric need
Computation:
Total fabric need = Area of rectangular prism
Area of rectangular prism = 2[lb + bh + hl]
Area of rectangular prism = 2[(15)(11) + (11)(24) + (24)(15)]
Area of rectangular prism = 2[165 +264 + 360]
Area of rectangular prism = 2[789]
Area of rectangular prism = 1,578 inch²

ABCD is a parallelogram. If a CDA - 57 then BCD-_?
The diagram is not to scale.
133
57
114
123
Answer:
57
Step-by-step explanation:
It is given in the question that length CDA = 57.
Since the shape is a parallelogram, then we know that length AD=BC and AB=CD.
CDA = CD + AD
BCD = BC + CD
Since BC=AD and CD=CD
BCD = BC + CD is the same as CD + AD = CDA
Therefore BCD is the same length as CDA = 57
In other words, CDA is made up of a long side and a short side = 57
BCD is also made up of a long side and a short side, and since the longs sides are equal to each other and the short sides are also equal to each other in a parallelogram, BCD is the same length as CDA = 57.
Hope this helped!
