Answer:

The percentage of fans that will be able to park in the stadium lot is 20%

Step-by-step explanation:

step 1

Find the number of fans who will be able to park in the stadium.

Multiply stadium capacity by two (because they arrive two fans per car)

7,000*2=14,000\ fans

step 2

Find out the percentage of fans that will be able to park in the stadium lot

we know that

70,000 fans represent the 100%

so

using proportion

Find out the percentage that represent 14,000 fans

Let

x ----> the percentage of fans that will be able to park in the stadium lot

\frac{70,000}{100}=\frac{14,000}{x}\\\\x=14,000*100/70,000\\\\x=20\%

So you should know that an independent variable is a variable that is not changed by other variables but a dependent variable does change by other variables.
So in this question, c is a dependent variable and m is an independent variable :))))

The weight of Jacob’s backpack is made up of the weight of the contents of the backpack as well as the weight of the backpack it
Dafna11 [192]
If the backpack (b) contains only textbooks (t) and notebooks (n), the total weight of the backpack is:

b+t+n

but notebooks are 4 pounds, so actually:

b+t+4

also, the backpack weights 2 pounds, so the total weight is:

2+t+4 =t+6
 now, "Seventy percent of <span> the total weight is textbooks. ", this means that


t=70%(t+6) - this equation can be used to determine the weight of the textbooks!

Melissa and Jane are planting trees. Melissa plants 10 trees in 1 hour. Jane plants 17 tree in 2 hours.
nadezda [96]

Answer:

6 hours

Step-by-step explanation:

Let both of them plan for  t hours to plant 111 trees n t hours

Melissa  can plants 10 trees in 1 hour

in t hours she can plant 10 t trees

Jane plants 17 tree in 2 hours

in one hour Jane can plant 17/2 trees

in t hours she can plant (17/2)t  trees.

Total trees planted by both of them in t hours in terms of t will be

10t + (17/2)t

= (10t*2 + 17t)/2

= (20t + 17t)/2

= 37t/2

but it is given that they planted 111 trees together

so 37t/2 should be equal to 111

37t/2 = 111

=> 37t = 111*2 = 222

=> t = 222/37 = 6.

Thus, it takes 6 hours for both of them to plant 111 trees together.

Kellan collected two sets of data and recorded them in the table. 
tigry1 [53]

Answer:

Set 2 has a wider spread and has range of 27

Explanation:

We are given the below two sets of data:

Set 1             Set 2

17                     81

13                     70

18                     94

24                     68

21                      95

Now, let's find the range of Set 1:

Range=Maximum-Minimum

        =24-13

        =11

Now, let's find the range of Set 2:

Range= Maximum -Minimum

        =95-68

        =27

Since, the Set 2 has more range, therefore, Set 2 has a wider spread and a range of 27

nikitadnepr [17]

Answer:

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

<em>Lacey's mom makes her a birthday cake in the shape of an "L" . Lacey loves frosting, so her mom covers the entire outside of the cake in frosting, even the bottom of the cake. </em>

<em>How much space does Lacey's mom cover in frosting? </em>

My answer:

As we know that the surface area of the the cake is made up of rectangles. The formula for find the area of a rectangle is A = lw

  • The area of rectangle ABCD: 4*2 = 8
  • The area of rectangle ADFE : 12*2 = 24
  • The area of rectangle TJVS : 4*2 = 8
  • The area of rectangle ESFV :9*2 = 18
  • The area of rectangle HTJG: 5*2 = 10
  • The area of rectangle CBHG: 2*8 = 16

The area of CDEVGJ = ABHTFS

= 4*12 + 4*5

= 68

So the total area is: 68 +68  +16+10+18+8+24+8 = 220

Hope it will find you well
