Answer:
since the sum of interior angles of hexagon is 720 °
you add the known angles
ie 115 +90+145+160
you get 510
subtract it from 720
you get 210
divide 210 by 3
you get 70
angle cde is 140
Answer:
∠ CDE = 140°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
let ∠ DEF be x then ∠ CDE = 2x
sum the interior angles and equate to 720
160 + 90 + 145 + 115 + 2x + x = 720 , that is
510 + 3x = 720 ( subtract 510 from both sides )
3x = 210 ( divide both sides by 3 )
x = 70
Then
∠ CDE = 2x = 2 × 70 = 140°

the perimeter of a square piece of confetti is 28 mm. how long is each side of the piece of confetti?
Answer:
7 mm
Step-by-step explanation:
A square has 4 equal sides, so the piece of confetti will have 4 sides of the exact same length.
Find the length of each side by dividing the perimeter by 4
28/4
= 7
So, each side of the confetti piece is 7 mm
What type of correlation exists between the temperature and the number of fruit bars sold? What is the real-world meaning of the slope of the line of best fit for the given scenario? There are approximately more fruit bars sold for every degree(s) the temperature rises
Answer:
There's no figure, but okay! The type of correlation that exists between the temperature and the number of fruit bars sold is a positive correlation.
The real-world meaning of the slope of the line of best fit for the given scenario is that: As the temperature increases, so too does the number of fruit bars sold.
I hope that helps you!! ^-^
Answer:

Determine the length of the rectangle if the area is 800 cm² and the breadth is 20 cm
Answer:
40 cm
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = lb ( l is the length and b the breadth )
Here b = 20 and A = 800 , then
l × 20 = 800 ( divide both sides by 20 )
l = 40 cm

6.3 + 6.8
8(3+6)
Answer:
6(3+8)
Step-by-step explanation:
6(3+8)= 6×3+6×8=18+48
this is the given value of A
The correct expressions for total area = 6x3 + 6x8 or 6(3+8)
What is rectangle?Rectangles are four-sided polygons with all internal angles equal to 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from a square in that its opposite sides are equal in length.
In the given figure,
Area of one room = 18 square feet
Area of second room = 48 square feet
Now since we can see that,
the width of both rooms is same,
therefore,
we have 6 as common factor of 18 and 48
As, 18 = 6x3
48 = 6x8
Total are of the given figure = 18 + 48
Since we know that,
Area of rectangle = length x width
Therefore,
area of both rooms = 18 + 48
= 6x3 + 6x8
= 6(3+8)
Hence,
The rooms total area of both rooms = 6x3 + 6x8 or 6(3+8)

Let the graph of g be a vertical stretch by a factor of 2, followed by a translation 5 units down of the graph of f(x) = e". Write a rule for g
Answer:
g(x) = 2e - 5
Step-by-step explanation:
f(x) = e
2 f(x) = 2e : vertical stretch by a factor 2
2 f(x) - 5 : transition 5 units down
g(x) = 2 f(x) - 5 = 2e - 5

Answer:
67.5 feet
Step-by-step explanation:
If 1 inch = 9 feet, and the model is 7.5 inches,
you just need to do 7.5 • 9 = 67.5 feet.
OR
7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5
63 + 4.5 = 67.5
*I'm pretty sure it says 1 inch = 9 feet and I'm also basing this off the fact that your work for question 2 is showing the same ratio of 1 inch = 9 feet

Matteo has &400 in his saving account. On average he spends $10 per week on buying apps. Luca has $200 in his savings account. He is saving $15 a week in order to buy a new Playstation. When will matteo and luca have the same amount of money?
Answer: By the 8th week.
Step-by-step explanation:
Let the time that matteo and luca have the same amount of money be represented by x.
The information given in the question can be formed into an equation as:
400 - 10x = 200 + 15x
Collect like terms
400 - 200 = 15x + 10x
200 = 25x
x = 200/25
x = 8
Matteo and Luca will have the same amount of money by the 8th week.

definition of a parallelogram a quadrilateral with both pairs of opposite sides parallel
five properties/theorems for parallelograms opposite sides are parallel, diagonals bisect each other, opposite sides are congruent, opposite angles are congruent, consecutive angles are supplementary
definition of a rectangle a quadrilateral with four right angles
rectangle theorems if a parallelogram is a rectangle, then its diagonals are congruent; if the diagonals of a parallelogram are congruent, then the paralellogram is a rectangle
five properties of a rectangle opposite sides are congruent and parallel; opposite angles are congruent; consecutive angles are supplementary; diagonals are congruent and bisect each other; all four angles are right angles
definition of a rhombus a quadrilateral with four congruent sides
rhombus theroems the diagonals of a rhombus are perpendicular; if the diagonals of a parallelogram are perpendicular, then the paralellogram is a rhombus; each diagonal of a rhombus bisects a pair of opposite angles
properties of a rhombus all parallelogram properties apply; all four sides are congruent; diagonals are perpendicular; the diagonals bisect opposite angles
definition of a square a quadrilateral with four right angles and four congruent sides
properties of a square the properties of a rectangle plus the properties of a rhombus; four right angles; all four sides are congruent
definition of a trapezoid a quadrilateral with exactly one pair of parallel sides
definition of an isosceles trapezoid a trapezoid with the legs congruent
isosceles trapezoid theroems both pairs of base angles are congruent; the diagonals are congruent
trapezoid median theorem the median of a trapezoid is parallel to the bases and its measure is one-half the sum of the measures of the bases, or median=1/2(x+y)

in these quadrilaterals, the diagonals are perpendicular rhombus, square
a rhombus is always a... parallelogram
a square is always a... parallelogram, rhombus, and rectangle
a rectangle is always a... parallelogram
a square is never a... trapezoid, because trapezoids only have one pair of parallel sides
a trapezoid is never a... parallelogram, rhombus, rectangle, or square, because trapezoids only have one pair of parallel sides
these quadrilaterals always have all four congruent sides rhombus, square

What is the length of segment QV?
32 units
36 units
40 units
44 units
Answer:
44
Step-by-step explanation:
because i just did the test
The length of the segment in the given figure is 44 units.
Consider triangle STR and ΔQTR.
We have to find the length of QV.
∠TRQ = ∠TRS = 90°
TR = TR (Common)
SR = RQ (Given)
So, ΔTSR ≅ ΔTQR ( By SAS Congruence Criterion)
So, By CPCT (Correspondence part of congruent triangle)
TS = TQ
2x+8=40
2x=32
Divide both sides by 2
x=16
Now segment QV=3x-4
3(16)-4
48-4=44 units

Georgia makes trail mix by mixing fruit
and nuts in a ratio of 3 to 2. If Georgia
mixes in 18 ounces of fruit, how many
Ounces of nuts should she add?
Answer: 12 ounces
Step-by-step explanation:
Let the ounces of fruits that should be added be represented by x.
Based on the information given in the question, this can be represented by:
3/2 = 18/x
Cross multiply
3 × x = 18 × 2
3x = 36
x = 36/3
x = 12
Therefore, 12 ounces of nuts should be added.
