How do you prove a quadrilateral is a Rhombus?

Answers

Answer 1

Answer:

There are two ways to do this depending on the information you know.

Step-by-step explanation:

In order for a quadrilateral to be a rhombus, the sides have to be of equal length, so proving that all four sides are the same length would be one way. A second way is to prove that diagonals connecting opposite corners are perpendicular bisectors (connect in such a way that they cut each other into equal pieces at right angles).

To feed his plants logan creates a mixture that requires 3/8 cup of plant food for every gallon of water. If he uses 10 1/2 gallons of. Water what is the total amount of. Plant food he needa

Answers

Answer:

[tex]3\ \frac{15}{16}[/tex]

Step-by-step explanation:

The mixture  requires 3/8 cup of plant food for every gallon of water

Then it requires (10 1/2)×(3/8) cup of plant food for 10 1/2 gallons of water

Now we have to calculate (10 1/2)×(3/8)

[tex]10\ \frac{1}{2} \ =\ \frac{10\times 2}{2} +\frac{1}{2} \ =\frac{20+1}{2} =\frac{21}{2}[/tex]

[tex]\frac{21}{2} \times \frac{3}{8} =\frac{63}{16} =3\ \frac{15}{16}[/tex]

NO LINKS!! Use the cylinder shown to mark each statement as true or false. Rewrite and correct any false statements.​

Answers

Problem 9

Answer: False

Reason:

The height of the cylinder is 2.5 ft. It's misleading because the cylinder is tipped onto its side, so it appears that 4 ft is the height. The height of any cylinder is always perpendicular to the circular base. It might help to rotate the paper so that the circular base is horizontal.

==============================================================

Problem 10

Answer: False

Reason:

The diameter of the base is 4 feet, which divides in half to 2 feet and it's the radius of the circle.

Area = pi*(radius)^2 = pi(2)^2 = 4pi

So the area expression should be either pi(2^2) or pi(4) or 4pi

==============================================================

Problem 11

Answer: True

Reason:

V = pi*r^2*h

V = 3.14*2^2*2.5

V = 31.4 cubic feet

This volume is approximate since pi = 3.14 is approximate.

In a certain Algebra 2 class of 21 students, 12 of them play basketball and 14 of them play baseball. There are 5 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?

Answers

The probability that a student is chosen randomly from the class plays both basketball and baseball is 4/21

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

If the total number of people in the class is 21 students, hence the total outcome is 21

Get the number of students that plays both basketball and baseball

n(U) = n(B)only + n(Ba)only + n(BnBa) + n(BuBa)'

21 = 6-x + 14-x + x + 5

21 = 25 -x

x = 25 - 21

x = 4

Hence 4 students play both basketball and baseball

Pr(basketball and baseball) = 4/21

Hence the probability that a student chosen randomly from the class plays both basketball and baseball is 4/21

Given :   Eitan rolls a fair six-sided die and a fair four-sided die simultaneously. A be the event that the sum of the dice is 8 and B be the event that Eitan rolls doubles

To find : probability of event A  , event B  , Event A or B  , Event A & B

Solution:

Six  Sides  Dice has { 1 , 2 , 3 , 4 , 5 ,6  }

4 Sides Dice has  = {  1 , 2 , 3 ,  4 }

Total possible outcome = 6 * 4  = 24

n(S) = 24

A  = Sum of Dice  = 8

(4 , 4)  , ( 5 , 3) , ( 6 , 2)

n(A) = 3

B  =   Double  ( means same number on each Dice )

B = ( 1 , 1) , (  2, 2) , ( 3 , 3) , ( 4, 4)

n(B) = 4

A U B  = ( 1 , 1) , (  2, 2) , ( 3 , 3) , ( 4, 4) ( 5 , 3) , ( 6 , 2)

n (A U B )   =  { 6 }

A ∩ B = { 4 , 4}

n(A ∩ B)  = 1

Probability of Event A  =  3/24  = 1/8

probability of Event B = 4/24   = 1/6

Probability of Event A or B  = 6/24  = 1/4

Probability of Event  A and B = 1/24

Find the area of the figure​

Answers

Answer:

132cm^2

Step-by-step explanation:

to solve for the area of this we can split it into smaller shapes and sum the areas afterward-

the top rectangle has an area equal to Length x Width

4x7 = 28cm^2

the centre rectangle is done similarly-

7x8 = 56cm^2

lastly the two triangles which are solved with base x height divided by two

now since we know that the centre piece is 7cm across, and that the two side triangles are equal in size, that means that we know the base to be 19-7 divided by 2 which gives 6 each-

[tex]\frac{(6)(8)}{2}[/tex] (2) = (6)(8) = 48cm

now summing them we have 28 + 56 + 48 = 132cm^2

Step-by-step explanation:

just solve them out

The expressions to the correct function combination is (f. g)(x).

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

f(x) = 12 - 61 – 27

g(t) = 1 - 9

Now,

To match the expressions to the correct function combinations, you can substitute the values of f(x) and g(t) into the expressions and simplify. For example:

( + 5)() = (f(x) + 5)(g(t))

( + 5)() = ((12 - 6x - 27) + 5)(1 - 9t)

( + 5)() = (17 - 6x)(1 - 9t)

( + 5)() = 17 - 153t - 6x + 54xt

Therefore, by the given equation the answer will be (f. g)(x).

A trapezoid has sides of length 11 inches, 1.5 inches, 11 inches, and 19.1 inches. What is the perimeter?

Answers

Answer:

The Perimeter of the trapezoid = 42.6 inches

Step-by-step explanation:

______

Formula:

let a , b , c , d be consecutively the lengths of the sides of the trapezoid

then

The Perimeter of the trapezoid  = a + b + c + d

___________________________________

Suppose a = 11 , b = 1.5 , c = 11 , d = 19.1

therefore,

The Perimeter of the trapezoid  = a + b + c + d

                                                     = 11 + 1.5 + 11 + 19.1

On x-axis between A and C are 6 -2 = 4 units

On y-axis between A and C are 1 + 7 = 8 units

AB = (1/3) BC

Divide the distance between AC in 3 pieces

On x-axis will have 4/3 units on each piece

On y-axis will have 8/3 units on each piece

Now move away from A the 1/3 distance

A (x= 6, y= 1)

B (x= 6 -(4/3) , y= 1 -(8/3))

Answers

Answer:

1. 144 m; 2. 720m²;

Step-by-step explanation:

1.

First we need to know how much edges are of the figure. Since there is 12, we need to multiple the length of an edge to how many of them are:

12 • 12 = 144 m

2.

Since one edge is 12 m, first calculate the plot of a little square (as there are 5 in the pic):

12 • 12 = 144 m² (one square)

Now we know that one square's plot is 144 m².

Since there is 5 of them, we need to multiply the plot 5 times, since there are five mini squares:

144 • 5 = 720 m²

Now we know the plot of the full figure.
