Which of the following statements is false?
A. A rhombus is a parallelogram.
B. Adjacent angles in a parallelogram are complementary.
C. The height of a trapezoid is the distance between its bases.
D. The diagonals of a parallelogram bisect each other.

Answer:

B

Step-by-step explanation:

Not much to say but that i the definition.  You sing the midpoint of each side, make a perpendicular line and see where the three perpendicular bisectors intersect.  

A is the incenter, C sounds like the Orthocenter and D sounds like the centroid.

Aside from being able to tell from the parts of the words, you just kinda have to memorize these.

The number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations

Combinations have to do with selection compared to permutation that has to do with the arrangement.

If a 3-member committee has to be formed from 2 teachers and 2 parents, the total committee is given as:

Total committee members  = 2 + 2

Total committee members = 4 committees

If 3-member committee has to be formed from them, the number of ways this can be done is given as:

4C3 = 4!/(4-3)!3!
4C3 = 41/3!
4C3 = 4 ways

Hence the number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations

Answer:

8 and 17

Step-by-step explanation:

Let the number x and y

Sum of numbers, x + y = 25 -----------( 1 )

One number exceeds other by 9,

 that is difference between the numbers is 9, x - y = 9

                                                                       => x = 9 + y   --------- ( 2 )

Substitute ( 2 ) in ( 1 )

( 9 + y ) + y = 25

2y = 25 - 9

2y = 16

y = 8

Substitute y = 8 in ( 2 ) : x = 9 + y

                                        = 9 + 8 = 17

Therefore the 2 numbers are 8 and 17

Answer:

The answer would be that one number is 8 and the second is 17.

The sum of these two numbers is 25, ad 17 and 8 have a difference of 9

Answer:

B, 33%

Step-by-step explanation:

Let us find the original price of four chairs without the special deal, and compare it with the deal to find the percent savings.

Step 1:

A customer must buy 4 chairs costing $75 each to recieve the deal. Let us multiply 4 by 75 to find the total cost without the deal:

[tex]4*75=\\300[/tex]

Step 2:

We now know the original cost of the 4 chairs, and the price of 4 chairs with a deal. Let us subtract the difference of costs and convert it into a percentage to find percent savings:

[tex]300-200=100\\\frac{100}{300} =\frac{1}{3}[/tex]

[tex]\frac{1}{3}=33[/tex]%

Therefore, B, the percent savings is 33%.

Answer:

La altura del depósito para que pueda contener 1000 metros cúbicos de agua es 2 m.

Step-by-step explanation:

Para calcular el volumen de un prisma rectangular, es necesario multiplicar sus 3 dimensiones: longitud*ancho*altura. El volumen se expresa en unidades cúbicas.

En este caso, se conoce la longitud y el ancho, cuyos valores son 25 y 20 metros. A su vez, se sabe que el depósito de agua debe contener 1000 m³. Entonces, siendo:

Volumen= longitud*ancho*altura

Y reemplazando los valores se obtiene:

1000 m³= 25 m* 20 m* altura

Resolviendo:

1000 m³= 500 m²* altura

[tex]altura=\frac{1000 m^{3} }{500 m^{2} }[/tex]

altura= 2 m

La altura del depósito para que pueda contener 1000 metros cúbicos de agua es 2 m.

Answer:

D. x ≈ 3.3, y = 15.7

Step-by-step explanation:

x = Opposite

y = Adjacent

16 = Hypotenuse

θ = 12°

To find x, we solve using the Trigonometric function of Sine

sin θ = Opposite/ Hypotenuse

x = Opposite

sin 12 = x/16

Cross Multiply

x = sin 12 × 16

x = 3.3265870531

Approximately, x ≈ 3.3

To find y, we solve using the Trigonometric function of cosine

cos θ = Adjacent/ Hypotenuse

y = Adjacent

cos 12 = y/16

Cross Multiply

y = cos 12 × 16

y = 15.650361612

Approximately, y ≈ 15.7

Therefore, x ≈ 3.3, y = 15.7

Option D is correct

Answer:

The granite countertop will cost $ 608.

Step-by-step explanation:

Given that a counter in Spencer's kitchen is 4 feet wide and 8 feet long, and Spencer wants to replace the counter with a granite countertop, which would cost $ 19.00 per square foot, to determine how much would the granite countertop cost the following calculation must be performed:

(4 x 8) x 19 = X

32 x 19 = X

608 = X

Therefore, the granite countertop will cost $ 608.

The volume occupied by a 350 pound sphere is 2.33 ft³.

Equation is an expression used to show the relationship between one or more numbers and variables.

Let y represent the weight of the sphere in pounds and x represent the volume in feet³, hence:

y = 150x

For a 350 pounds sphere:

350 = 150x

x = 2.33 ft³

Answer:

median is 2

Step-by-step explanation:

I arranged the numbers from low to greatest and found the "middle" number basically

Answer:

2

Step-by-step explanation:

In order to find the Median of a data set, you must first put the numbers in the data set in order so you'd get:1, 1, 1, 1, 2, 2, 4, 6, 6, 8, 48 Then you would count on each side to the middle and whichever digit is in the middle that is your median.

The student forgot to sort the values first.

The sorted data set is {162, 169, 174, 177, 178, 187, 192, 194, 196}

Cross off the first four items, and cross off the last four items. You'll find that 178 is the only thing left, so it's right in the middle. This is the median.

Another way to find the median is to notice that there are n = 9 items in the list, so n/2 = 9/2 = 4.5 which rounds to 5 represents the slot number where the median is located. The value 178 is in slot 5. This trick only works if n is odd.

The range is the difference between the min and max, so,

range = max - min = 196-162 = 34

The student got the range part correct.

Median = 178
