Find the perimeter of the figure. Round to the nearest tenth.
Answer:
perimeter = 20.9 units
Step-by-step explanation:
perimeter
perimeter = distance around two dimensional shape
= addition of all sides lengths
perimeter of the figure= AB+BC+CD+ADdistance formula:
[tex]d = \sqrt{( x_{2} - x_{1}) {}^{2} + ( y_{2} - y_{1}) {}^{2} } [/tex]
1) distance of ABA(-3,0) B(2,4)
x1 = -3 x2 = 2
y1 = 0 y2 = 4
(substitute the values into the distance formula)
[tex]ab = \sqrt{(2 - ( - 3)) {}^{2} + (4 - 0) {}^{2} } [/tex]
[tex]ab = \sqrt{5 {}^{2} + 4 {}^{2} } [/tex]
[tex]ab = \sqrt{41} [/tex]AB = 6.4 units
2) distance of BCB(2,4) C(3,1)
x1 = 2 x2 = 3
y1 = 4 y2 = 1
[tex]bc = \sqrt{(3 - 2) {}^{2} + (1 - 4) {}^{2} } [/tex]
[tex]bc = \sqrt{1 {}^{2} + ( - 3) {}^{2} } [/tex]
[tex]bc = \sqrt{10} [/tex]
BC = 3.2 units
3) distance of CDC(3,1) D(-4,-3)
x1 = 3 x2 = -4
y1 = 1 y2 = -3
[tex]cd = \sqrt{( - 4 - 3) {}^{2} + ( - 3 - 1)) {}^{2} } [/tex]
[tex]cd = \sqrt{( - 7) {}^{2} + ( - 4 ){}^{2} }[/tex]
[tex]cd = \sqrt{65} [/tex]
CD = 8.1 units
4) distance of ADA(-3,0) D(-4,-3)
x1 = -3 x2 = -4
y1 = 0 y2 = -3
[tex]ad = \sqrt{( - 4 - ( - 3)) {}^{2} + ( - 3 - 0) {}^{2} }[/tex]
[tex]ad = \sqrt{( - 1) {}^{2} + ( - 3) {}^{2} } [/tex]
[tex]ad = \sqrt{10} [/tex]
AD = 3.2 units
perimeter of figure= AB+BC+CD+AD
= 6.4 + 3.2 + 8.1 + 3.2
= 20.9 units

A- y = 3/8x + 2
B- y = 3/8x - 2
C- y = -3/8x + 2
D- y = -3/8x - 2
Answer:
y = 3/8 x - 2
Step-by-step explanation:
Put 8y on the other side to get
8y + 16 = 3x
8y = 3x - 16 and thus
y = 3/8 x - 2

. Find three consecutive square numbers whose sum is 149.
Answer:
The three consecutive square numbers that added together give 149 are 6, 7 and 8.
Step-by-step explanation:
To determine which are the three square consecutive numbers that added together add up to 149, the following calculation must be performed:
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16
5 x 5 = 25
6 x 6 = 36
7 x 7 = 49
8 x 8 = 64
9 x 9 = 81
10 x 10 = 100
Thus, we can see that 36 + 49 + 64 gives the result 149. Therefore, the three consecutive square numbers that added together give 149 are 6, 7 and 8.

What is the answer for -3p(p+2) - (2p+3) using the distribution method?
Answer: -3p^2-8p-3
Step-by-step explanation: By distributing we get, -3p^2-6p-2p-3. Then simplify accordingly.
To figure out this problem, we need to break down the steps:
-3p(p + 2) - (2p + 3)
because -3p is next to the equation in parentheses, (p + 2), you should multiply -3p into both p and 2
-3p x p = -3p² (if you multiply a variable (p) by another of the same variable with no power, it becomes squared)
-3p x 2 = -6p
so the first part of the equation went from -3p(p + 2) to -3p² -6p
and the second part of the equation has no multiplying to do
so now we add like terms!
-3p² -6p - 2p + 3
-3p² -8p + 3
order from greatest power to least power (first goes the number/variable with the highest power, then the term with a variable, and lastly the number. Right now it is currently in the correct order).
-3p² -8p + 3 is your final answer
Two friends are planning a vacation. They are deciding between Arizona and New York. The airfare for Arizona is $95 per person and the airfare for New York is $150 per person. The hotel in New York is $120 per night and the hotel in Arizona is $150 per night. They would share a hotel room. After how many nights would the trip's cost be equal to each other?
Answer:
7
Step-by-step explanation:
Let number of nights spent in both the locations be [tex]x[/tex]
Airfare for Arizona for 2 persons for two way journey = [tex]95\times 4=\$380[/tex]
Airfare for New York for 2 persons for two way journey = [tex]150\times 4=\$600[/tex]
Cost of night spent in Arizona = [tex]150x[/tex]
Cost of night spent in New York = [tex]120x[/tex]
Cost of going and coming back from Arizona = [tex]380+150x[/tex]
Cost of going and coming back from New York = [tex]600+120x[/tex]
Now the costs should be equal so
[tex]380+150x=600+120x\\\Rightarrow 150x-120x=600-380\\\Rightarrow x=\dfrac{220}{30}\\\Rightarrow x=7.33\ \text{nights}[/tex]
The number of nights is approximately 7 at which the cost of the trip becomes equal.
What is the image of A(1,-3)?
use the following transformations with each question:
Reflection across the x-axis
Reflection across the y-axis
Reflection across the y = x
Reflection across the y = -x
Step-by-step explanation:
Given A(1 , -3)
Reflection across the x -axis
= A'( 1 , 3)
Reflection across the y-axis
= A'( -1 , - 3)
Reflection across the y = x
= A' ( -3 , 1)
Reflection across the y = - x
=A'( 3 , - 1)

(Always, sometimes, never question) If two sides and a non-included angle of one triangle are congruent to two sides and a non-incldued angle of another triangle, then the two triangles are congruent.
A: always
B: sometimes
C: never
sometimes
the description is describing SSA, which is NOT a type of congruence.
since the congruent angle is non-included (which means it is not in between the two congruent sides), we can't say for sure if the triangles are congruent.
this is because the third side of the triangle is unknown, and that side might not be congruent to the same side in the other triangle.

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the doghouse?
A right trapezoid with top side 7 feet and height 7 feet. The bottom side is extended to the right with 3 more feet.
24.5 square feet
59.5 square feet
70 square feet
147 square feet
Answer:
70 square feet
Step-by-step explanation:
This is because the correct formula for this problem is: base x height
Using this formula, you first have to find the base of the trapezoid. Since the square's base is 7 ft, and the triangle's base is 3 ft, you add these together and get 10 ft as a base. For the height, you need the square's height which is 7 ft. Then you multiply and get 70 ft.
hope this helps <3!
Two parallel lines are crossed by a transversal. Vertical and parallel lines h and i are cut by transversal g. At the intersection of lines h and g, the uppercase right angle is 70 degrees and the bottom left angle is x degrees. What is the value of x?
Answer:
x = 70°
Step-by-step explanation:
There are two vertical and parallel lines h and i. Also, a transversal line g cuts across these parallel lines. The intersection of the transversal line and line h produces an upper right angle of 70° and bottom left angle of x°.
These angles x and 70 are vertically opposite angles, hence:
x = 70° (vertically opposite angles are equal to each other)
Answer:
70

Event B is a subset of the sample space S.
what is represented by the shaded area?
A. the complement of B
B. the intersection of B and S
C. the union of B and S
D. the complements of S
Step-by-step explanation:
The shaded area shows the region where it is enclosed in sample space S but does not include the subset B.
Hence it is the complement of B. (A)
If event B is a subset of the sample space S, hence the area represented by the shaded part is complement of B
Set theoryThe set is a collection of members and things.
According to the venn diagram given, the whole set including the set B is the universal set.
The part not shaded is not part of the universal set, hence, we name them the complement of a set.
If event B is a subset of the sample space S, hence the area represented by the shaded part is complement of B

-4u = -48
u = 12
Answer:
u = 12
Step-by-step explanation:
4u - 8u - 15 = -63
Step 1: Combine 4u and -8u
-4u - 15 = -63
Step 2: Add 15 to both -15 and -63
-4u = -48

Which of the following is an equation of the line through (11, –3) and (7, 9)?
Answer:
y = -3x + 30.
Step-by-step explanation:
The slope of line = (9- (-3)) / (7 - 11)
= 12/-4
= -3.
We use the point-slope form of a straight line:
y - y1 = m(x - x1) where m = slope = -3 and (x1, y1) = (7, 9)
y - 9 = -3(x - 7)
y - 9 = -3x + 21
y = -3x + 21 + 9
y = -3x + 30.
