Answer:

8ft^{2} of  outdoor carpet is needed for the hole

Step-by-step explanation:

The question is not properly formatted

The expression for the dimension is 4ft * 2ft* 5ft

Given data

Area A =  ?

Length l =  4ft

Width w=  2ft

Height h =  5ft

since we are required to find the area in ft^{2}

we do not need the height for our calculation

we know that the expression for area is

area= length* width\\area= 4*2\\area= 8ft^{2}

Evaluate.<br> 6[5(3-9)-1]+2 the answer of this divided by the answer of this one 7(8-2)+4
Snowcat [4.5K]


According to PEMDAS, these are the steps for evaluating this equation -

3-9=-6

-6 x 5 = -30 - 1 = -31

-31 x 6 = -186, + 2 = -184

Now our first answer is -184 (I think this is correct)

Next thing we'll do is the second equation

8-2 = 6

6 x 7 = 42

42 + 4 = 46

Now, we can divide :)           -184 / 46 equals -4

Hope this helps :D!

Solve the system and give your answer as a coordinate point in the form (k, c) k+c=100 51k+11c=2500
Aleks [24]

Answer:

k = 35, c = 65

Step-by-step explanation:

Solve the following system:

{c + k = 100 | (equation 1)

{11 c + 51 k = 2500 | (equation 2)

Swap equation 1 with equation 2:

{11 c + 51 k = 2500 | (equation 1)

{c + k = 100 | (equation 2)

Subtract 1/11 × (equation 1) from equation 2:

{11 c + 51 k = 2500 | (equation 1)

{0 c - (40 k)/11 = -1400/11 | (equation 2)

Multiply equation 2 by -11/40:

{11 c + 51 k = 2500 | (equation 1)

{0 c+k = 35 | (equation 2)

Subtract 51 × (equation 2) from equation 1:

{11 c+0 k = 715 | (equation 1)

{0 c+k = 35 | (equation 2)

Divide equation 1 by 11:

{c+0 k = 65 | (equation 1)

{0 c+k = 35 | (equation 2)

Collect results:

Answer: {c = 65 , k = 35
