What I need to know is how to find angels of a parallelogram.
Answer:There are six important properties of parallelograms to know:
Opposite sides are congruent (AB = DC).
Opposite angels are congruent (D = B).
Consecutive angles are supplementary (A + D = 180°).
If one angle is right, then all angles are right.
The diagonals of a parallelogram bisect each other.
Each diagonal of a parallelogram separates it into two congruent

Find the measurement.
Answer:
∠ C = 35°
Step-by-step explanation:
The sum of the 4 interior of a kite = 360°
The opposite angles D and F are congruent, that is
∠ F = 125°
Sum the 4 angles and equate to 360°, thus
∠ C + 125° + 75° + 125° = 360°
∠ C + 325° = 360° ( subtract 325° from both sides )
∠ C = 35°

Solve similar triangles (advanced)
Answer:
x = 24Step-by-step explanation:
6 = x
8 x + 8
8x = 6x + 48
8x - 6x = 48
2x = 48
x = 48/2
x = 24
The value of x is 6.
What are similar triangles?Those triangles look the same but are different in size.
And in similar triangles,
the corresponding sides are in proportion to each other and the corresponding angles are equal to each other.
Given:
The triangle ABC and AED are similar triangles.
So,
the corresponding sides are in proportion of each other.
ED/CB = AD / AB

1. Anne wants to join five pieces of paper together. She plans to use 3 rectangular pieces of the same size and 2 square pieces of the same size. The length of each rectangular piece is 3 1/2 feet. The width of each rectangular piece, w, is the same as the length of each square piece. The expression below can be used to find the total surface area of the five pieces of paper. Anne decides that the width, w, of the rectangular pieces should be 2 feet. What is the total surface area, in square feet, of all five pieces of paper?
Answer and explanation:
Surface area of a rectangle = length * width
Surface area of a square = a² where a is length of a side
To find total surface area of the the five pieces of paper, we add up all the areas of all the shapes
Given that length of rectangle =3.5
And width = 2
Area of rectangle =3.5*2=7
Area of 3 rectangles given they are all equal = 7*3=21
Since width of rectangle equal to width of square and all sides of square are equal
Area of square = 2 *2 =4
Area of the two squares =4*2=8
Total surface area of the five plane shapes = 21+8= 29
Andre rode his bike at a constant speed. He rode 1 mile in 5 minutes. Which of these equations represents the amount of time t (in minutes) that it takes him to ride a distance of d miles?
t = 5d
t = 1/5d
t = d + 4
t = d - 4
Answer:
the first one
Step-by-step explanation:
Answer:
A) t=5d
Step-by-step explanation:
Since the problem states "He rode 1 mile in 5 minutes", that means for every mile Andre travels, it will take him 5 minutes for each mile.
Therefore, the equation that best works is t=5d because the coefficient is 5 where it's the slope representing 5 minutes per mile.
Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply.
A. 400 • 0.32
B. 400 • 3.2
C. 400 • 1.32
D. 400 + 400(0.32)
E. 400 • 400(1.32)
Answer:
Expressions C and D correctly determine the markup price.
Step-by-step explanation:
A markup in mathematics is when an object's price is raised by a certain percentage. Therefore, because we are told that the telescope is originally $400 and is marked up by 32%, we can actually mathematically evaluate this.
When you markup a price, you multiply the original price by [tex]1+x[/tex], where x is the percentage at which the object is marked up. However, x needs to be in decimal form for it to work out.
[tex]\frac{32}{100} = \small\boxed{0.32}[/tex]
Therefore, with this new decimal, we can add 1 to it.
[tex]1 + 0.32=\small\boxed{1.32}[/tex]
Finally, we multiply this result by the original price.
[tex]1.32 \times 400=\small\boxed{528}[/tex]
Therefore, we can already confirm that Expression C is one way to find the markup price.
We can eliminate expression A because it did not use the formula [tex]1+x[/tex]. It only uses the decimal form of the percentage.We can eliminate expression B because the division to convert from the percentage form to the decimal form is flawed (the expression divided by 10 instead of 100) and also forgot to add 1 to the determined value.Now, we can test the math for expressions D and E to see if either of these will equal $528.
Expression D is basically saying to add 32% of 400 to the original price. This would work out because we marked up the original price by 32%. Therefore, we can confirm that Expression D is also an expression that can be used to determine the markup price.
[tex]400 + 400(0.32)\\400(0.32) = 128\\400 + 128 = \small\boxed{528}[/tex]
Finally, we also need to check expression E. This expression is saying to add the already marked up price to 400. This would not be correct.
[tex]400 \times 400(1.32)\\400(1.32) = 528\\400 \times 528 = \small\boxed{\$ 211,200}[/tex]
Therefore, it has been determined that Expression C & Expression D are both equations that will find a markup price.
292500 rounded to the nearest 1000
Answer:
293000
Step-by-step explanation:
Since were rounding to the nearest thousand, we're looking at the hundred digit. If it's 5 or great, we round up. If it's 4 or less, we round down.
In this case, it's 5. So we round 292500 up to 293000

We can see 22 is being added to the given function f(x) to get the transformed function.
Note: According to transformation rule, y = f(x) +k shift k units up.
22 is being added to the original function. So, function would shift 22 units up that is y-intercept is 22 spaces higher.
Therefore , correct option is : The y-intercept is 22 spaces higher.
Answer:
the y-intercept is 22 spaces higher.

What is the diameter of a circle with the equation (x – 4)2 + (y + 6)2 = 64?
a. 4
b. 8
c. 16
d. 64
Answer:
16Step-by-step explanation:
step one:
given data
we are given the equation of the circle as
[tex](x -4)2^ + (y + 6)^2 = 64[/tex]----------------1
We know that the general equation for a circle is
[tex]( x - h )^2 + ( y - k )^2 = r^2[/tex]--------------2
comparing the two equations above, we can immediately compare the term on the other side of the equality sign that is
r^2=64
square root both sides
r=√64
r=8
since the radius is 8, hence the diameter is
d=2
r= 2*8
=16

Answer:
No. are 35&43
Step-by-step explanation:
Let the one no. Be= X
Then the other no.= X+8
Sum of both no.= X+ X+8= 2X+8
When sum is increased by 17 = 2X+8+17=95
2X+25=95
2X=70
X=35
Other no=X+8= 35+8=43
