Answer:

  Y = 7.2

Step-by-step explanation:

We can multiply each element of the set by 5/6 and see which result is an integer. We find 5(7.2)/6 = 6, an integer.

  Y = 7.2

Answer:

12×5=60

1/2×4×12=24

24×2=48

60+48=108

=108cm²

Answer:  108cm%2F%222+cm%22=54 .

Then you would add more rows like that for a total of

72cm%2F%222+cm%22=36 rows.

Step-by-step explanation:

many 2cm by 2cm square can be used to cover the rectangle without any spaces or overlapping.

It is possible because 72 and 108 are both divisible by 2.

You can start by lining up in row 54 such 2cm by 2cm squares along with one of the 108cm long sides,

Answer:

13/36

Step-by-step explanation:

1 - 2/3 equals 1/3 which is inside the parenthesis

square the number in parenthesis (1/3) and it equals 1/9

multiply the 2 fractions 1/4 and 1/9 to get 1/36

finally add 1/3 with 1/36

12/36 + 1/36 would equal 13/36

Answer:

option C.

Step-by-step explanation:

since the graph y = 6x is shrunk by a factor of ½

it becomes y = 3x

to find one coordinate of this graph we put x = 1 so that we get y = 3

so one point we have is (1, 3).

and the other point is origin

[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]

now this graph is translated 9 units in the negative y direction

so the point that initially was (0, 0) now becomes (0, -9).

we see that the only graph passing thru (0, -9) is C.

so the answer is option C.

Answer:

rounding is used to make long/rough calculations cleaner or easier

Step-by-step explanation:

Answer:

Rounding is used in instances where you can only have a limited number of digits or You must round to the nearest digit.

Step-by-step explanation:

For example lets say i have the problem 12.5 + 4 + 3.2.

I am told to round up to the nearest whole number.

After adding all the numbers up, I find I have 19.7 since the tenths place is a 7, I would round up leaving my final answer as 20.

Answer:

1.31

Step-by-step explanation:

3.28 - 1.97

p=70°

q=32°

r=38°

Answer:

Solution given:

r=38°[inscribed angle on a same arc are equal]

p=½*140°=70°[inscribed angle is half of the central angle]

<OBA=38°[base angle of isosceles triangle]

again

<C=<B[inscribed angle is half of the central angle]

70°=<OBA+q

70°=38°+q

q=70°-38°

q=32°

Answer:

Step-by-step explanation:

1985:

x = 5 years  ( 1980 to 1985- 5 years)

0.142x + 1.93 = 0.142*5 + 1.93

                     = 0.71 + 1.93

                     = $ 2.64

1999:

x = 19 years

0.142x + 1.93 = 0.142*19+ 1.93

                     = 2.698 + 1.93

                     =4.628 =  $ 4.63

2010:

x = 30 years

0.142x + 1.93 = 0.142*30 + 1.93

                     =  4.26 + 1.93

                     = $ 6.19

Answer:

4!

Step-by-step explanation:

In word MAXIMUM, consonants are M & X. According to the question itself, consonants should not occur together.

So, we have to put vowels at each even position; only then the condition will be satisfied.

We can put this in 3! ways (permutations of A, I & U).  

For odd positions we can put 3-M's & a X. Total ways is 4!/3!   (as repetitions of M).

Hence, the answer is 4!/3! x 3! = 24 ways.  

24=4!.

Answer:

(A) Over the interval [-2.5, 0.5], the local maximum is 2.

Step-by-step explanation:

"Over the interval [-2.5, 0.5], the local maximum is 2."

Correct. The local maximum is the maximum, or highest point, of the graph in a certain area of interval. In [-2.5, 0.5], the highest point is at the y-value of 2.

"As the x-values go to positive infinity, the function's values go to negative infinity."

Wrong. As the x values go to positive infinity (meaning they go to the right, or positive side of the graph), the function goes up, meaning the function's values go to positive infinity.

"The function is decreasing over the interval (-1, 0.75)."

Wrong. Only from [-1, 0] is where that area of the graph decreases. The other half of it, (0, 0.75), is where the graph increases.

"The function is negative for the interval [-2, 0]."

Wrong. Only from [-1, 0] is the function negative. In the interval [-2, -1], the function is positive.

Answer:

2.) (3,-2)

3.) (5,3)

4.) *Still trying to solve*

Step-by-step explanation:

2.)

Step 1.

   5x + 4y = 7

    3x - 4y = 17

+ ------------------

    8x      =   24

    8              8

         x = 3

Step 2.

    5x + 4y = 7

    5(3) + 4y = 7

     15 + 4y = 7

     -15          -15

      4y =  -8

      4        4

        y = -2

Final Answer: (3,-2)

3.

Step 1.

    4x + 5y = 35

         x = 2y - 1

   4(2y - 1) + 5y = 35  

    8y - 4 + 5y = 35

      13y - 4 = 35

            +4     +4

        13y = 39

        13      13

        y = 3

Step 2.

    x = 2y - 1

    x = 2(3) - 1

     x = 6 - 1

     x = 5

Final Answer: (5,3)

B. {All numbers less than 2}

Step-by-step explanation:

X + 5 < 7

Subtract 5 from each side

X + 5-5 < 7-5

x<2

All numbers less than 2

Step-by-step explanation:

The position of the median of an even data set is 1/2(8+1)=4.5

That is between two values, 4 and 5.

(5x-10+3x+30)/2=82

(8x+20)/2=82

(8x+20)=41

8x=41-20

8x=21

x=21/8

Answer:

i) The distance between Sarah's house and the school is 9

ii) The distance between the school and the library is 5

iii) The distance between the library and the park is 9

iv) The distance between the park and Sarah's house is 5

2) The total distance Sarah travels is 28

Step-by-step explanation:

The given coordinates of the locations are;

Sarah's house (2, -5)

The school (2, 4)

Library (-3, 4)

Park (-3, -5)

Sarah's journey is;  From the house → The school → Library → Park → House

The distance, d, between two coordinate points, (x₁, y₁) and (x₂, y₂) is given as follows;

d = [tex]\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

i) Therefore, the distance between Sarah's house ((x₁, y₁) = (2, -5)) and the school ((x₂, y₂) = (2, 4)), d₁, is d₁ = √((2 - 2)² + (4 - (-5))²) = 9

Sarah's house → The school = 9

ii) The distance between the school ((x₁, y₁) = (2, 4)), and the library, ((x₂, y₂) = (-3, 4)), d₂ = √((-3 - 2)² + (4 - 4)²) = 5

The school → Library = 5

iii) The distance between the library ((x₁, y₁) = (-3, 4)), and the park ((x₂, y₂) = (-3, -5)), d₃ = √((-3 - (-3))² + (-5 - 4)²) = 9

The library → The park = 9

iv) The distance between the park ((x₁, y₁) = (-3, -5)), and Sarah's house ((x₂, y₂) = (2, -5)), d₃ = √((2 - (-3))² + (-5 - (-5))²) = 5

The park → Sarah's house → 5

2) The total distance = 9 + 5 + 9 + 5 = 28.

Answer:

(x+6)^2 +(y-4)^2 = 49

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 +(y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x- -6)^2 +(y-4)^2 = 7^2

(x+6)^2 +(y-4)^2 = 49
