What is a quadrilateral?A quadrilateral is a four-sided polygon with four edges and four corners in geometry. The word comes from the Latin words quadri, a variant of four, and latus, which means "side." A quadrilateral is a closed shape that has four sides, four vertices, and four angles. It's made by connecting four non-collinear points. The sum of quadrilateral interior angles is always 360 degrees.
A rectangle is a quadrilateral with four right angles in Euclidean plane geometry. It can also be defined as an equiangular quadrilateral because all of its angles are equal; or a parallelogram with a right angle. A square is a rectangle with four equal-length sides.
A parallelogram is a simple quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are equal in length, and its opposite angles are equal in size.

A tablespoon is equivalent to about 4 teaspoons. A recipe calls for 2/3 cup of sugar for every 1/2 teaspoon vanilla. What is the unit rate in tablespoons
per cup?
Answer:
I understand the exercise is about unit rates, but why go out of the way to state false information? A tablespoon is exactly 3 teaspoons!
Anyway,
(1/2 tsp)/(2/3 cup) * (1tbsp)/(4tsp) = 1/2 * 3/2 * 1/4 = 3/16 tbsp/cup

Kira is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges an initial fee of $35 and an additional 60 cents for every mile driven.
Company B charges an initial fee of $42 and an additional 50 cents for every mile driven.
For what mileages will Company A charge less than Company B?
Write your answer as an inequality, using m for the number of miles driven.
Answer:
m < 0.7
Miles less than 0.7
Step-by-step explanation:
Company A: 60m + 35
Company B: 50m + 42
60m + 35 < 50m + 42
60m - 50m < 42 - 35
10m < 7
m < 7/10 (0.7)

Hi there!
We are given two exterior angles. Don't panic! We know that exterior angles form a linear pair, which means they add up to 180 degrees.
180-130=50
180-96=84
Now that we have those angles, how can we work out the value of x?
Turns out that all the angles in any triangle add up to 180 degrees.
So
180-84-50=46 degrees.
So the value of x is 46 degrees.
Now let's work out the value of x in the next problem.
180-126=54
180-54-43=83 degrees
So the value of x in this problem is 83 degrees.
Let's move on to the third problem.
At first, it seems like we do not have enough information.
If we know that the right angle is 90 degrees (it is shown by a little square), then we have enough information.
180-90-43=47 degrees
So the value of x is 47 degrees.
Hope this helps you!

PLEASE HELP!!!!! ASAP
thank you so much!
Answer:
a. 53.68
b. 53.53
Step-by-step explanation:
a. Step 1: Approximate the value for [tex]\sqrt{62}[/tex]:
Since [tex]\sqrt{62}[/tex] is close to [tex]\sqrt{64}[/tex] (which is 8), this value can be approximated as a number that is less than but very close to 8. I chose 7.9.
The expression becomes 6(7.9)+2π
Step 2: Approximate the value for 2π
Since π is approximately 3.14, 2π is approximately 6.28.
The expression becomes 6(7.9)+6.28
Step 3: Use order of operations
6(7.9)+6.28=47.4+6.28=53.68
b. Step 4: If allowed, use a calculator to check how close your approximation is to the actual value
[tex]6\sqrt{62} +2\pi =53.5272[/tex]
The approximation 53.68 is decently close to the actual value, so no minor math errors were made.
Answer:
54 and 53.53 see below
Step-by-step explanation:
Estimate the square root first. 7x7 = 49 and 8x8=64 so you can use 8 for your estimate. You can also estimate Pi as 3.
Now you have:
(6 x 8) + 2(3) which is 48 + 6 = 54
Using your calculator you get
47.244 + 6.283 = 53.53 rounded to the nearest hundredth

on a coordinate grid what is the distance of (-2,4) and (5,4)
Answer:
the distance is 7 units
Step-by-step explanation:
Since the we calculate the distance between (-2,4) and (5,4) and those points have the same y=4 coordinate then they are both part of a horizontal line.
The distance is found by looking at the x-axis.
From -2 to 5 so is form -2 until 0 is (2 )+ (5 )more = 7

Distance = 28.5
Hence,
Speed = 28.5/0.75
= 38 miles/hr

A pack of 24 crayons costs the manufacturer $0.05 to make and is sold to the stores for $0.25. The

. It represents
[ Select]
The answers is P(C)=2c P(C) =5c P(C) =10c
We want to find equations for the different markups for the manufacturer and the stores that sell the crayons.
We know that a pack of 24 crayons costs $0.05 to make.
Is sold to stores for $0.25
The stores sell it for $0.50
Now we want to get the markup equation for the manufacturer, this is:
Markup = 100%*(price - cost)/(cost) = 100%*($0.25 - $0.05)/$0.05 =400%
For the store it is:
Markup = 100%*($0.50 - $0.25)/($0.25) = 100%
For the composition of these two I assume you refer to the total markup (notice that these are not functions, we can't make a composition if we do not have a variable).
Comp = 100%*($0.50 - $0.05)/($0.05) = 900%

There were 110 students at a creative writing workshop last year. This year there are 132 students. What is the percent of increase in the number of students at the workshop?
Answer:
20% increase
Step-by-step explanation:
the initial number is 110 so lets take that as a 100%
the final number is 132 and it will be x
110/132=100/x
we multiply the numerator of the first fraction with the denominator of the second fraction and vice versa.
110*x=132*100
110x=13200
x=120
Then we deduct 120 by 100 to know how much the percent increase is
(120-100)%=20% :)
