WILL GIVE BRAINLIEST + MAX POINTS!!!
Sara is working on a Geometry problem in her Algebra class. The problem requires Sara to use the two quadrilaterals below to answer a list of questions. Part A: For what one value of are the perimeters of the quadrilaterals the same? (Hint: The perimeter of a quadrilateral is the sum of its sides.) Part B: For what one value of are the areas of the quadrilaterals the same? (Hint: The area of a quadrilateral is the product of its base and height.) Please help me outtt!

Answer:

86

Step-by-step explanation:

Answer:

9 yrs ago

Step-by-step explanation:

(50-x)(20-x) = 451

x^2-70x + 1000 = 451

x^2-70x + 549 = 0

(x-9)(x-61) = 0

x = 9 (if it was 61 yrs ago, the father and son both wouldnt be a live)

Answer:

14.99 + 25.99 - X = 30.98

14.99 + 25.99 - X

Step-by-step explanation:

They all relate to what the question is asking, and make the most sense

Answer:

b = 20 cm.

Step-by-step explanation:

Define and explain:

This is a right triangle, so the Pythagorean Theorem applies.

The Pythagorean Theorem states that the sum of the squared legs will equal the squared length of the hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side; the hypotenuse is always diagonal from the small square indicating a right angle.

Solve:

[tex]a^2+b^2=c^2[/tex]

[tex]a,b-legs[/tex]

[tex]c-hypotenuse[/tex]

[tex]15^2+b^2=25^2[/tex]

[tex]225+b^2=625[/tex]

[tex]625-225=400[/tex]

[tex]b^2=400[/tex]

[tex]b=20[/tex]

Conclude:

Therefore, the length of the unknown side is 20 centimeters.

Answer:

C

Step-by-step explanation:

Answer:

Height = 4 cm and slant height = 5 cm

Step-by-step explanation:

Given that,

The surface area of the cone, A = 75.4 cm²

Radius, r = 3 cm

The surface area of the cone is given by the formula as follows :

[tex]A=\pi r^2+\pi rl[/tex]

Put all the values,

[tex]75.4=3.14\times 3^2+3.14\times 3\times l\\\\75.4=28.26+9.42l\\\\75.4-28.26=9.42l\\\\47.14=9.42l\\\\l=\dfrac{47.14}{9.42}\\\\l=5\ cm[/tex]

Also,

[tex]l^2=r^2+h^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{5^2-3^2}\\\\h=4\ cm[/tex]

Hence, the height of the cone is 4 cm and the slant height is 5 cm.

Answer:

A - since the median can be any number we know of. B - Again the median can be any number we know of, since it is a undetermined amount. E - The range can be 10 flights, this is because it is not a determiend value, and it is possible for the value to be 10.

Step-by-step explanation:

Wrong answer reasoning:

The mode doesnt need to be 9 if there is more than 1 mode, so that isnt it. Eliminating D. The mean can most definatly be determinded if we know the values. This elimnates C. The mean can be 6.875, but we dont know, so we can assume it IS 6.875. This eliminates F.

Hope this helps!

Answer:

Angle M=14.25°

Step-by-step explanation:

Sin(M)=16/65

Sin^-1(16/65)=14.25°

Step-by-step explanation:

please I'm not sure for the numbers 3 and 2.

for number 10,

2/3x -4 = 3 +5

2/3x = 8+4

2/3x = 12

2x= 12 x 3

2x = 36

x = 18

and for number 4

(y+1)/5 - (y-2)/4 = -1

to clear out the fraction, multiply throughout by 20

after multiplying, we have

4(y+1) -5(y-2)= -20

4y+4-5y+10 =-20

14 -y = -20

-y = -20 + 14

-y = -6

y = 6

Answer:

[tex]-\infty < y < -2[/tex]

Step-by-step explanation:

Given

The attached graph

Required

The range of the graph

From the graph we can see that the curve points down towards the y-axis,

This means that y starts from a [tex]-\infty[/tex] number

Coming up, the curve stops increasing at 2 and becomes horizontal; This means that y ends at 2

Hence, the range is: [tex]-\infty < y < -2[/tex]

Answer:

A.) Independent

B.) Independent

C.) Dependent

D.) Independent

E.) Dependent

F.) Independent

Step-by-step explanation:

To find - Select from the following pairs of events all the pairs that are independent.

A. Draw a 2 of clubs from a standard deck of 52 cards, keep it, then draw a 2 of diamonds.

B. Draw a 3 of spades from a standard deck of 52 cards, replace it, then draw a 5 of hearts.

C. Roll a number cube. Then roll again if the first roll is a 6.

D. Roll a 2 on a number cube and spin a 3 on a spinner.

E. Events A and B, where P(A) = 0.4, P(B) = 0.2, and P(A and B) = 0.8.

F. Events A and B, where P(A) = 0.1, P(B) = 0.5, and P(A and B) = 0.05.

Proof -

We know that,

Independent events are the events that does not depend on the previous events.

Also,

If A and B are two independent events, then

P(A and B) = P(A) * P(B)

Now,

A.)

Draw a 2 of clubs from a standard deck of 52 cards, keep it, then draw a 2 of diamonds.

Here,

Event 1 - Draw a 2 of clubs from a standard deck of 52 cards

Event 2 - keep it, then draw a 2 of diamonds.

These Events are independent

Because

Event 1 is about picking a card that is club

Event 2 is about picking a card that is diamond

And Diamond and spades are 2 different types of card in a pack of standard deck.

So, they are not related to each other.

So,

Both the Events are Independent.

B.)

Draw a 3 of spades from a standard deck of 52 cards, replace it, then draw a 5 of hearts.

Event 1 is about picking a card that is spade

Event 2 is about replacing the card to heart.

These Events are independent

Because

And spade and heart are 2 different types of card in a pack of standard deck.

So, they are not related to each other.

So,

Both the Events are Independent.

C.)

Roll a number cube. Then roll again if the first roll is a 6.

Event 1 is Roll a number cube.

Event 2 is Roll again if the first roll is 6.

These Events are Dependent

Because

Event 2 is dependent on Event 1.

If Event 1 given no 6 then Event 2 would not happen

If Event 1 given 6 then Event 2 would happen.

So, They are related to each other

So,

Both the Events are Dependent.

D.)

Roll a 2 on a number cube and spin a 3 on a spinner.

Event 1 is Roll a 2 on a number cube

Event 2 is spin a 3 on a spinner

These Events are independent

Because

Cube and spinner are two different objects.

So, they are not related to each other.

So,

Both the Events are Independent.

E.)

Events A and B, where P(A) = 0.4, P(B) = 0.2, and P(A and B) = 0.8.

These Events are Dependent

Because

P(A and B) = P(A)*P(B)

⇒0.8 = 0.4*0.2

⇒0.8 = 0.08

But they are not equal

So, they are not independent Events.

F.)

Events A and B, where P(A) = 0.1, P(B) = 0.5, and P(A and B) = 0.05.

These Events are independent

Because

P(A and B) = P(A)*P(B)

⇒0.05 = 0.1*0.5

⇒0.05 = 0.05

They are not equal

So, they are independent Events.

Answer:

The area of the rectangle is 4 sq yards.

Step-by-step explanation:

Given that,

The length of the rectangle, [tex]L=\dfrac{2}{13}\ yards[/tex]

The breadth of the rectangle, B = 26 yards

We need to find the area of the rectangle. The formula for the area of a rectangle is given by :

A = LB

Put all the values,

[tex]A=\dfrac{2}{13}\times 26\\\\A=2\times 2\\\\A=4\ yd^2[/tex]

So, the area of the rectangle is 4 sq yards.

Answer:

m<G = 59°

Step-by-step explanation:

Recall: the angle formed outside a circle when 2 secants intercept is equal to half of the difference of the intercepted arcs

m<G = ½(arc TE - arc HF)

m<G = ½(175 - 57)

m<G = ½(118)

m<G = 59°

Given:

[tex]\frac{AD}{DC}=\frac{BE}{EC}[/tex]

To Prove:

AB║DE

Solution:

Since, corresponding sides of ΔACB and ΔDCE are proportional,

[tex]\frac{AD}{DC}=\frac{BE}{EC}[/tex]

Both the triangles will be similar.

ΔACB ~ ΔDCE [By SAS property of similarity]

Therefore, ∠1 ≅ 2 [CPCTC]

Since, ∠1 and ∠2 are the corresponding angles

Therefore, AB║DE [Converse of corresponding angles theorem]

9514 1404 393

Answer:

  x = 6.4

Step-by-step explanation:

The corresponding sides are proportional, so we have ...

  horizontal/vertical = x/(5+3) = 4/5

  x = 8(0.8) = 6.4 . . . . . . multiply by 8

Answer:

Where is the picture

Step-by-step explanation:

The figure shown above is triangle. The area of the triangle is a= 1/2base times height.

Base  is 10 .  The height is 6.

A= 1/2bh

A= 1/2*10*6

A= 1/2*60

A= 30

Or you can find the area of the triangle separately and add them up.

First triangle :

The half of the base is 10/2= 5

B= 5  H= 6

A= 1/2*6*5

A=  15

Second triangle :

b= 5

h= 6

a= 1/2*5*6

a= 15

Add up them both areas 15+15= 30

Answer:

x  = 73

Step-by-step explanation:

A circle is 360 degrees

4x-5 + x = 360 degrees

5x - 5 = 360 degrees

5x = 365 degrees

Divide by 5

5x/5 = 365/5

x =73
