The Gomez’s deck is shown below. The deck is a regular hexagon. It has a perimeter of 45 units. What is the are of the deck
Answer:
The area of the deck is of 146.14 squared units.
Step-by-step explanation:
Regular hexagon:
A regular hexagon has 6 sides, all with the same measure.
Perimeter of a regular hexagon:
The perimeter of a regular hexagon with side x is given by:
[tex]P_h = 6x[/tex]
Area of a regular hexagon:
The area of a regular hexagon with side x is given by:
[tex]A_h = \frac{3\sqrt{3}x^{2}}{2}[/tex]
It has a perimeter of 45 units.
This means that:
[tex]6x = 45[/tex]
[tex]x = \frac{45}{6}[/tex]
[tex]x = 7.5[/tex]
What is the are of the deck
[tex]A_h = \frac{3\sqrt{3}x^{2}}{2} = \frac{3\sqrt{3}*(7.5)^{2}}{2} = 146.14[/tex]
The area of the deck is of 146.14 squared units.
Shawn is placing a fence around a circular garden with 15 foot diameter. How many feet of fencing will Shawn need to buy to enclosed the garden. Use 3.14 for π. Round the answer to the nearest foot
(A) 47 feet
(B) 48 feet
(C) 177 feet
(D) 707 feet
Answer:
47 feet
Step-by-step explanation:
Shawn is placing a fence around a circular garden with diameter of 15 foot
π = 3.14
Therefore the circumference can he calculated as follows
= π × diameter
= 3.14 × 15
= 47.1 feet
Hence the circumference to the beatesr tenth is 47 feet

Make y the subject of the formula
Answer:
[tex] y = \frac{w - x^2}{-2z} [/tex]
Step-by-step explanation:
Given:
w = x² - 2yz
Required:
Solve for y
Solution:
[tex] w = x^2 - 2yz [/tex]
Subtract x^2 from not sides
[tex] w - x^2 = - 2yz [/tex]
Divide not sides by -2z
[tex] \frac{w - x^2}{-2z} = \frac{-2yz}{-2z} [/tex]
[tex] \frac{w - x^2}{-2z} = y [/tex]
[tex] y = \frac{w - x^2}{-2z} [/tex]

Answer:
[tex]r = 107 \\ q + s = 180 - 107 \\ = 73 \\ q = 73 \div 2 \\ = 36.5[/tex]
I have to solve for x
The 3 angles of a triangle equal 180.
Subtract the bottom 2 angles from 180 and you get 50
So 8x + 2 = 50
Subtract 2 from both sides:
8x = 48
Divide both sides by 8
X = 6

1/3into a percent and a decimal
Answer:
33% or .33
Step-by-step explanation:
Divide 1/3 = .3333 (repeating). I would round to the nearest hundreths place:
1/3 = .33
For the precentage, multiple 0.33 by 100:
100 * 0.33 = 33%
Suppose Anthony Ianni attempted 18 baskets in a basketball game. If the ratio of baskets made to baskets missed is 1:5, how many baskets did Ianni make?
Answer:
Number of baskets Lanni make = 3 basket
Step-by-step explanation:
Given:
Total attempt = 18 times
Ratio(Basket make : Basket missed) = 1:5
Find:
Number of baskets Lanni make
Computation:
Number of baskets Lanni make = Total attempt x [Basket make ratio]
Number of baskets Lanni make = 18 x [1/(1+5)]
Number of baskets Lanni make = 3 basket
Solve the inequality x +8 > 3

What is the 10th term in -9,-6,-1,6,15
Answer:
90
Step-by-step explanation:
This is an increasing sequence, with -9 as its first term. The first increase is +3, then +5, +7, and +9. The differences increase by 2 each time. The sixth term will be 15 + 11, and the seventh would be 15 + 11 + 13. We can follow this pattern to get to the tenth term. 15 + 11 + 13 + 15 + 17 + 19 = 90

I only need help on questions 6 and 7. (Use the congruent figure on top to answer 6 and 7.)
Answer:
See below.
Step-by-step explanation:
All statements of congruent angles and congruent segments are correct.
A similarity statement can be written ...
Write a similarity statement ...
ABCD ~ HJKL
The reason written in the problem is incorrect. The polygons are similar, not congruent, so you cannot state that they are congruent as a reason for them to be similar.
This is the correct reason:
"The reason as why the two shapes are similar is that each angle A, B, C, D is congruent to each corresponding angle H, J, K, L, respectively, and the lengths of corresponding sides are proportional."
"A similarity ratio is a ratio that compares the lengths of the corresponding sides of two similar polygons. The ratio is written in the same order as the two
polygons."
For the similarity ratio, we use two corresponding sides.
AB = 8; HJ = 12
AB/HJ = 8/12 = 2/3
The similarity ratio of ABCD to HJKL is 2/3.

HOW DO YOU GRAPH USING LINER PROBLEMS
Answer:
You need to plot points onto the graph
Step-by-step explanation:
It takes only 2 points to draw a graph of a straight line. In other words, if we can find two points that satisfy the equation of the line, then the line can be accurately drawn. But it can be more than 2 points as well. IT CANNOT BE 1. Just 1 point can fo anything at all. You cannot make a linear line or a line in general with just one point. You need 2 or more to make a line.

The length of a photograph of Mr. Lemley playing golf is 1475 inches. If the area
of the photo is 33/20 square inches, what is the width of the photograph? *
Answer:
1.12 × 10^-3
Step-by-step explanation:
The computation of the width of the photograph is as follows:
As we know that
Area of the rectangle = length × width
33 ÷ 20 square inches = 1475 inches × width
So, the width is
= Length ÷ area
= 1475 inches ÷ (33 ÷ 20 square inches)
= 1.12 × 10^-3
A test is worth 60 points. Multiple-choice questions are worth 2 points, and
short-answer questions are worth 5 points. If the test has 15 questions, how
many multiple-choice questions are there?
O A. The number of multiple-choice questions minus the number of
short-answer questions is 60.
OB. The number of multiple-choice questions times the number of
short-answer questions is 15.
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
D. The number of multiple-choice questions plus the number of
short-answer questions is 60
Answer:
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of multiple-choice questions
y is the number of short-answer questions.
Multiple-choice questions are worth 2 points, and short-answer questions are worth 5 points.
This means that:
[tex]2x + 5y = 60[/tex]
The test has 15 questions.
This means that:
[tex]x + y = 15[/tex].
Which means that option C is the correct answer.
Answer:
C. The number of multiple-choice questions plus the number of short-answer questions is 15.
Step-by-step explanation:
x + y = 15
The length of a rectangle is 9 yd more than twice the width x. The area is 455 yd?.
Write an equation in terms of x that represents the given relationship.
Answer:
x * (2x + 9) = 455
Step-by-step explanation:
To express the width in terms of x, given information
x = width
The given information says the length is 9 more than 2 times the width. Length can be expressed in terms of x like this.
2x + 9 = length
The area of a rectangle is length x width, and the given area is 455.
x * (2x + 9) = 455 or 2x^2 + 9x = 455
The equation in terms of x of the area of the rectangle should be [tex]2x^2 + 9x = 455[/tex]
Given that
The length of the rectangle is 9 yards i.e. more than twice the width. i.e.. 2x + 9.And, the width is x.The area is 455 yards.The area of the rectangle is
= [tex]length \times breadth[/tex]
[tex](2x + 9( (x) =455 \\\\ 2x^2 + 9x = 455[/tex]
Therefore we can conclude that The equation in terms of x of the area of the rectangle should be [tex]2x^2 + 9x = 455[/tex]

What is the equation of the line?
Answer:
So first y intercept
SO the first part where the line hits the Y axis is 2
So the y intercept is 2 Which leaves 2 choices .
Now from that y-intercept or from any point, find the slope by just rising or running till you reach a point which in this case would be
Y=1/2x+2
Quick help fast pleaseeeeee
Answer:
No.
Step-by-step explanation:
I am not exactly sure, but you can't divide x and y, which would already make the question null and void. The simplest form would be the form it is in right now.
