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,

Really hope this helped couldnt really see it

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:

find the value of:Cos = 0.54

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

Step-by-step explanation:

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

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:

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:

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)

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.

Step-by-step explanation:

x=y³/z

(y³/z) to the power of a = y to the power of b

[tex] {y}^{3a} \div {z}^{a} = {y}^{b} [/tex]

[tex] {y}^{3} \div z = {y}^{b \div a} [/tex]

[tex] {y}^{3 \div b} \div {z}^{1 \div b} = {y}^{1 \div a} [/tex]

[tex] {y}^{3 \div b} = {y}^{1 \div a} {z}^{1 \div b} [/tex]

[tex] {y}^{b} = {z}^{c} [/tex]

[tex]z = {y}^{b \div c} [/tex]

[tex] {y}^{3 \div b} = {y}^{1 \div a} \times ({y^{b \div c} })^{1 \div b} [/tex]

[tex] {y}^{3 \div b} = {y}^{1 \div a} \times {y}^{1 \div c} [/tex]

as b/c × 1/b = 1/c

and so we see based on the exponents that

3/b = 1/a + 1/c
