In rectangle ABCD, the diagonals AC and BD intersect at E. If AE = 2x+4 and BD = 8x - 32, then the length of AC is​

Answers

Answer 1

The length of the diagonal AC is equal to the length of the diagonal BD,

which is 8×10 - 32 = 48.

Response:

The length of AC is 48

Which properties of a rectangle is used to find the length the diagonal AC?

The given parameters are;

The diagonals of the rectangle are AC and BD

The point of intersection of the rectangle = Point E

AE = 2·x + 4

BD = 8·x - 32

Required:

The length of AC

Solution:

The diagonals of a rectangle bisect each other and have equal length.

Therefore;

AE = [tex]\mathbf{\frac{1}{2}}[/tex] × BD

Which gives;

[tex]2 \cdot x + 4 = \mathbf{\dfrac{1}{2} \times \left(8 \cdot x - 32\right)}[/tex]

2·x + 4 = 4·x - 16

4·x - 2·x = 4 + 16 = 20

2·x = 20

[tex]x = \dfrac{20}{2} = 10[/tex]

x = 10

AC = 2 × AE

Which gives;

AC = 2 × (2·x + 4) = 4·x + 8

The length of AC = 4 × 10 + 8 = 48

What is the greatest common monomial factor of _________ ?

Answers

Answer:

A

Step-by-step explanation:

find the value of w and x​

Answers

x = 42°

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°

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

Answer:  33.3% approximately

Explanation:

Ignore the 15 pretzels. We're only focusing on the fish crackers.

3 orange + 5 yellow + 7 green = 15 total fish crackers

Of that total, 5 are yellow.

So approximately 5/15 = 1/3 = 0.333 = 33.3% of the crackers are yellow.

For the angles shown in the diagram, which statements are true? Select all that apply.
The sum of m∠3 and m∠4 is 180°.
The sum of the measures of the adjacent interior angle and one of the remote interior angles is equal to the measure of the exterior angle.
∠3 is supplementary to ∠1.
m∠4 = m∠1 + m∠2.
m∠1 + m∠2 + m∠3 = 180°

Answers

The statements that are true regarding the diagram given are:

What is the Triangle Sum Theorem?

The triangle sum theorem states that all the three interior angles in a triangle have a sum of 180 degrees all together.

Thus, in the diagram given, the statements that are all true are:

m∠3 + m∠4 = 180° (angles on a straight line)

m∠4 = m∠1 + m∠2 (external angle theorem)

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

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].

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:

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 = 2

Let’s simplify the second equation to find out the value of x.

x/y = 2 x = 2y

Now, let’s substitute the value of x into the first equation.

x + y = 152y + y = 153y = 15y = 5

Now, let’s substitute the value of y into the simplified second equation.

x = 2yx = 2(5)x = 10

Hence, the value of x and y are 5 and 10 respectively.

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.

Find the values of x and y.

Answers

Answer:

Given, x,y and 40 are the angles of a triangle.

Therefore, x+y+40=180

x+y=140

The difference between the two angles x and y is 30.

Therefore, x−y=30 ....(2)

Add equations (1) and (2), we get

2x=170

⇒x=85

Substitute this value n equation (2), we get

85−y=30

⇒y=85-30

⇒y=55

Therefore, angles of a triangle are x=85, y=55 and 40.

Answer:

Step-by-step explanation:

for x :

180° - 40° = 140°  

40° / 2 = 20°

x = 20°

for y :

20° + 90° = 110°

180° - 110° = 70°

x = 70°

Answers

Answer:

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
