Answer: If by m you mean meters and not a variable, then you get 4 for the length of the sides. If you mean m as a variable, then the answer is 2m

Step-by-step explanation: First simplify the equation by squaring 4. This gives you the area, which is 16. Then take the square root of 16 to get the area, which is 4. If m is a variable in the equation then you must take the square root of  (4m^2) and the answer you get for the side length you get is 2m

Answer:

5/8=20/32

Step-by-step explanation:

Answer:

f = 6 cm

g =  8 cm

Step-by-step explanation:

ABCD   f*g = 48

ABCE   f*g + 1/2 (4*f) = 60

48 + 2f = 60

2f = 12

f = 6

g = 48/6 = 8

Answer: It would be 2x-19

Step-by-step explanation:

Answer:

the Largest shed dimension is 13.5 ft by 13.5 ft

Largest Area is 182.25 ft²

Step-by-step explanation:

Given that;

Perimeter = 54 ft

P = 2( L + B ) = 54ft

L + B = 54/2

L + B = 27 ft

B = 27 - L ------------Let this be equation 1

Area A = L × B

from equ 1, B = 27 - L

Area A = L × ( 27 - L)

A = 27L - L²

for Maxima or Minima

dA/dL = 0

27 - 2L = 0

27 = 2L

L = 13.5 ft

Now, d²A/dL² = -2 < 0

That is, area is maximum at L = 13.5 using second derivative test

B = 27 - L

we substitute vale of L

B = 27 - 13.5 = 13.5 ft

Therefore the Largest shed dimension = 13.5 ft by 13.5 ft

Largest Area = 13.5 × 13.5 = 182.25 ft²

Answer:

[tex]Scale\ Factor = \frac{1}{2}[/tex]

ABC dilated

Step-by-step explanation:

Given

Triangles ABC and DEF

Required

Determine the scale of dilation

First, we pick a side on ABC

[tex]AB = 6[/tex]

Pick a corresponding side on DEF

[tex]DE = 3[/tex]

The scale factor is then calculated as:

[tex]Scale\ Factor = \frac{DE}{AB}[/tex]

[tex]Scale\ Factor = \frac{1}{2}[/tex]

i.e. ABC was dilated by 1/2

Answer:

59.02%

Step-by-step explanation:

SO SORRY THAT THIS IS LATE anyway what you is minus the biggest number by the smallest number which would be 3,529 - 2,806 = 723

BECAUSE 3,529 is the original number you would do 723 / 3,529 = 0.5902521

then you would times that number by 100

0.5902521 x 100 = 59.02%

hope this helps

Step-by-step explanation:

Everything the parallel lines has the same slope

[tex]y = mx + b[/tex]

m = slope

b = y intercept

then the equation of the line is:

[tex]y = 3x - 1[/tex]

Answer:

It's 15

c. x=15 is a solution but x=9 is not

Answer:

4) d. 30%. 5) 55/21. 6) 16

Step-by-step explanation:

4) 6/20 × 100 = 30%

5) Change mixed numbers to fraction. So you're getting 58/7 - 17/3. LCM = 21

= 174 - 119 / 21

= 55 / 21

6) Change to fraction

8/3 ÷ 1/6

= 8/3 × 6/1

= 16

Step-by-step explanation:

Answer:

Step-by-step explanation:

The required equation is translated as:

Step-by-step explanation:

yx = k, where k is a real constant.

When y = 30, x = 3.

=> k = (30)(3) = 90.

Hence when y = 6, x = k/y = (90)/(6) = 15.

Answer:

6^5

Step-by-step explanation:

put the 5 and make it tiny on top of the 6

Answer:

6^5 to give u the same thing as 6×6×6×6×6×6

Answer:

Step-by-step explanation:

your questions may have left out what the slope is.. but.. what ever it is.. just use m =  ( your number )

and plug it into this slope-intercept formula  [ y = mx +b }

y = mx -56 ..  just plug your slope into the variable m

Answer:

75 child tickets and 100 adult tickets were sold.

Step-by-step explanation:

Given that adult tickets cost $ 6 and children's tickets cost $ 2, knowing that 175 tickets were sold for $ 750, to determine how many child tickets were sold the following calculation must be performed:

2 x 175 = 350

750 - 350 = 400

6 - 2 = 4

400/4 = 100

175 - 100 = 75

100 x 6 = 600

75 x 2 = 150

Therefore, 75 child tickets and 100 adult tickets were sold.

Step-by-step explanation:

For every 3 blocks across, the line graph goes up by 2 blocks. Therefore the slope of the line is 2/3.

The line also intercepts the y-axis at -3.

Hence the slope-intercept form is y = 2/3 x - 3.
