Mathematics

Licemer1 [7]4 years ago

The answer would be A) 2,640.

In order to find this we must first find an amount of people per square feet. Since we are given that 10 people fit in a 5x5 square, we know that 10 people fit in 25 square feet. This will be the basis for our final calculation.

Now we need to find how many square feet we have. Since it is a quarter of a mile long, we'll divide the number of feet in a mile by 4.

5,280/4 = 1320.

Now we take the length and multiply it by the width, which is 5ft.

1320 * 5 = 6,600 square feet.

So we now know the size of the crowd. We can use that and multiply it by the factor that we found at the start to find the number of people.

6,600 square feet * 10 people/ 25 square feet = 2,640 people.

The area of a rectangle is 72cm square. Length,/, of the rectangle is 6 cm longer than the width w
Butoxors [25]
As you haven't specifically stated what exactly the question is, I will be assuming that the question is most likely asking for what the dimensions ( length and width ) of the rectangle is. With this in mind, I will be answering the question so here I go...


STEP-BY-STEP SOLUTION:

Let's solve this problem step-by-step.

Let's first establish the formula for the area of a rectangle as displayed below:

Area = Length × Width

A = lw

From this, we will establish the values for each of the parts in the area formula using the information given in the problem as displayed below:

A = 72cm^2

l = w + 6

w = w

Now, we will substitute these values into the area formula and then make ( w ) the subject as displayed below:

A = lw

72 = ( w + 6 ) ( w )

72 = w ( w + 6 )

72 = w^2 + 6w

0 = w^2 + 6w - 72

0 = w^2 + 12w - 6w - 72

0 = w ( w + 12 ) - 6 ( w + 12 )

0 = ( w + 12 ) ( w - 6 )


w + 12 = 0

w = 0 - 12

w = - 12


w - 6 = 0

w = 0 + 6

w = 6

As the answer must be positive as measurements are always positive, the answer must be the option which is a positive number.

Therefore:

w = 6

Using the equation we made for the length before, we can substitute the value of ( w ) to obtain the value of the length as displayed below:

l = w + 6

l = ( 6 ) + 6

l = 12


FINAL ANSWER:

The dimensions of the rectangle are:

Length = 12cm

Width = 6cm

12.68 is greater than 12.8 because 68 is better than correct
77julia77 [94]

Answer:That is incorrect. 12.8 is greater than 12.68 because .8 is greater than .68

Step-by-step explanation: Since “68” has been placed after the decimal, it is actually “.68” which is less than 1. From here, you have to figure out if .8 or .68 is closer to the number 1 and since .8 is closer, point 12.8 is greater than 12.68

Help!!<br> (2x-5) -3i= 7 +2yi
mrs_skeptik [129]

Answer:

2x-12/2y+3

Step-by-step explanation:

Let's solve for i.

2x−5−3i=7+2yi

Step 1: Add -2iy to both sides.

−3i+2x−5+−2iy=2iy+7+−2iy

−2iy−3i+2x−5=7

Step 2: Add -2x to both sides.

−2iy−3i+2x−5+−2x=7+−2x

−2iy−3i−5=−2x+7

Step 3: Add 5 to both sides.

−2iy−3i−5+5=−2x+7+5

−2iy−3i=−2x+12

Step 4: Factor out variable i.

i(−2y−3)=−2x+12

Step 5: Divide both sides by -2y-3.

i(−2y−3)

−2y−3

=

−2x+12

−2y−3

i=

2x−12

2y+3

Answer:

i=

2x−12

2y+3
