quadrilateral corn has coordinates C(-4,1) O(-3,3) R(2,3) N(0,-1). what is the most specific name for the quadrilateral. justify your conclusion
Answers
The quadrilateral is a trapezoid because it presents two parallel sides with different lengths.
For solving this question, first you need to plot the coordinate points given on the Cartesian graph. After that, you should connect the plotted points with a line. With this, you can see an image of a parallelogram, but you need to inform your specific name.
Main Types of Quadrilateralssquare: it presents all side equals and angles equal to 90°;rectangle: it presents all angles equal to 90°. On the other hand, the opposite sides are equals (same length);rhombus: it presents all side equals and angles different than 90° (two acute and two obtuse angles );trapezoid: all the sides may not have equal length also it presents two parallel sides.The image plotted from the coordinate points shows a quadrilateral with two parallel sides and different lengths. Therefore, this quadrilateral is a trapezoid.

Which net matches the solid figure shown below?
Answers
find the value of w and x
Answers
because angle x and 42° are alternate angles which are equal (these angles are found on a ‘Z’ shape)
y = quite some steps (need to work out other letters beforehand)
w = 70° because w and 70° are corresponding angles (also equal and are found on ‘F’ shapes, thus F is easier to see if the line is extended or mathematically called along the transversal, the transversal is just a line that intersects two parallel lines)
The angle opposite x is also 42° because vertically opposite angles are equal.
Now, all the angles in a triangle add to 180° so y + w (70) + 42 = 180
y = 180-112
y = 68°

How much material, in square inches, is needed to make the flag? square inches If the material costs $0. 15 per square inch, how much will Marta spend on materials to make the flag? $.
Answers
The amount of material needed by Marta to make the flag is;
[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] square inch.
The total cost of making the flag is;
[tex]\rm 0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] dollar.
Given
Marta is making a flag with the given dimensions.
The perimeter of the flag is 100 inches.
Let us consider that the flag has a triangular shape.
Hero's formula;According to the Hero's formula;
The area of the triangle is given by;
[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where, s is the semi perimeter and a, b, and c are the sides of the triangle.
Semi perimeter s = P/2,
Since the perimeter of the flag is 100 inches.
[tex]\rm S=\dfrac{100}{2}\\\\S=50[/tex]
The dimensions of triangular shape are [tex]\rm d_1, d_2 \ and \ d_3[/tex].
Then,
The area of the triangular flag becomes;
[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]
So the amount of material needed to make the flag is;
[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]
Therefore,
The cost of material = C = $0.15 per square inch
So the total cost in making the flag will be;
[tex]\rm C\times A=0.15 \times A\\\\=0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].
Hence, The amount of material needed by Marta to make the flag is [tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].

The answer is 70 feet
Step-by-step explanation:
Given;The area of therectangular billboard covered by the ribbon was approximately 4200 square feetThe width of the billboard was approximately 60 feet.To Find;The height of this billboard = ?Formula;Area = Width × HeightHere, We know the area so,
Area = Width × Height
Height = Area ÷ Width
H = 4200 ÷ 60 feet
H = 70 feet
Thus, The height of the billboard is 70 feet

solve system of equations:
-8x - 10y = 10
3x + 2y = 12
Answers
Answer:
x=10
y = -9
Step-by-step explanation:
-8x - 10y = 10
3x + 2y = 12
Multiply the second equation by 5
5(3x + 2y) = 12*5
15x+10y = 60
Add this to the first equation to eliminate y
-8x - 10y = 10
15x+10y = 60
-----------------------
7x + 0y = 70
Divide by 7
7x/7 = 70/7
x = 10
Now find y
3x+2y = 12
3(10) +2y = 12
30 +2y =12
Subtract 30 from each side
2y = 12-30
2y = -18
Divide by 2
2y/2=-18/2
y = -9

add the length of the top and the bottom face them multiply the sum of those two by the perpendicular height between them and the product is to be divided by 2 : ((a+b)h)/2)
Answer:
16 ft²
Step-by-step explanation:
First you'll find the area of the rectangle forming in the trapezoid:
3 x 4 = 12
Next, you'll think logically and understand that if BC is 3 feet, EF is also 3 feet. So, you'll subtract 5 - 3 = 2, so AE and FD is 1 foot.
So, you'll now multiply to find the area of the whole trapezoid:
4 x 1 = 4
So:
4 + 12 = 16
On Monday a shop receives $60.30 by selling bottles of water at 45 cents each
How many bottles are sold?
Answers
Answer:
134 bottles
Step-by-step explanation:
For this, I set up a proportion :
60.30/x = 0.45/1
60.30(1) = 0.45x
60.30/0.45 = 0.45x/0.45
x = 134 :)
Answer:
134 bottles
Step-by-step explanation:
conversion of dollars to cent:
$1 equals to 100 cents.
$60.30 will be (60.30*100) cents → 6030 cents
Bottles sold: total money / each bottle cost.
→ 6030 / 45
→ 134
So 134 bottles are sold for 45 cents to earn $60.30 or 6030 cents.
Given triangle ABC is similar to triangle DEF, angle A measures 30 degrees, and angle F measures 50 degrees, what is the measure of angle B?
Answers
Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees

which set of pairs represents a function? PLSS HURRY (100 POINTS)
Answers
Answer:
{(0, 0), (1, 2), (2, 4), (3, 4)}
Step-by-step explanation:
A set of ordered pairs that represent a function is one in which each different ordered pair has a unique x-coordinate (so no two different ordered pairs can have the same x -coordinate).
Therefore, {(0, 0), (1, 2), (2, 4), (3, 4)} is a function as each different ordered pair has a unique x-coordinate.
The other sets all have different ordered pairs that share the same x-coordinate and so these sets do not represent functions.
The vertical line test is also used to determine whether a graph represents a function. If the vertical line intersects the graph only once, then the curve represents a function. This test can be applied to ordered pairs, in that if two ordered pairs have the same x-coordinate but different y-coordinates, they will be on the same vertical line and therefore do not represent a function.
The sum of 2 numbers is 15 and their qoutient is 2
Answers
x + y = 15------(1)
x/y = 2------(2)
y = 15 - x
put this value in eq 2
x/(15-x) = 2
x = 2 (15 - x)
x = 30 - 2x
2x + x = 30
3x = 30
x = 10
y= 15 - x
y = 15 - 10
y = 5
Solution:
Given:
x + y = 15x/y = 2Let’s simplify the second equation to find out the value of x.
x/y = 2 x = 2yNow, let’s substitute the value of x into the first equation.
x + y = 152y + y = 153y = 15y = 5Now, let’s substitute the value of y into the simplified second equation.
x = 2yx = 2(5)x = 10Hence, the value of x and y are 5 and 10 respectively.

Sam has a party with snacks. One bowl of snacks has a mixture of fish crackers. There are 15 pretzels, 3 orange, 5 yellow, and 7 green fish crackers in the bowl.
What percent of the fish crackers are yellow?
Answers
Explanation:
Ignore the 15 pretzels. We're only focusing on the fish crackers.
