Answer:

4000 is size of a crowd walking in a charity fundraising March.

Step-by-step explanation:

Given:

Dimensions of rectangular space 10 feet by 12000 feet

So we can say that,

Length = 1200 ft

Width = 10 ft

Now we will calculate the area of rectangular space which is given by

Hence Area will be = [tex]length\times width= 10\ ft \times 1200 \ ft= 12000 \ ft^2[/tex]

Now we know that 40 people occupy a rectangle measuring 10 feet by 12 feet.

Length = 12 ft

Width = 10 ft

Area = [tex]length\times width= 10\ ft \times 12 \ ft= 120 \ ft^2[/tex]

It says that 40 people are occupied in 120 [tex]ft^2[/tex]

So how many people will be there in 12000 [tex]ft^2[/tex]

By using unitary method we get,

Number of people = [tex]\frac{40\times 12000 \ ft^2}{120 \ ft^2} = 4000 \ peoples[/tex]

Size of a crowd walking in a charity fundraising March is 4000.

Answer:

4,000 people

Step-by-step explanation:

49 people occupy 120 ft^2

Dimensions of crowd: 10×1,200=12,000

120 ft^2/40 people = 12,000 ft^2/x people

X=4,000

Answer:

There are 44 yellow slabs.

Step-by-step explanation:

Multiply 1/5 x 55. This gives you 11. 55 - 11 = 44.

The number of yellow slabs in a garden patio is 44.

Given that, a garden patio is covered with grey slabs and yellow slabs 1/5 of the slabs are grey.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

The ratio of grey to yellow slabs are 1:4.

There are 55 slabs in total.

Number of grey slabs =1/5 ×55

= 11

So, the number of yellow slabs

= 55-11

= 44

Therefore, the number of yellow slabs in a garden patio is 44.

Answer:

131040

Step-by-step explanation:

10*9*8*7*26

=131040

Final answer:

To calculate the unique student numbers possible, multiply the number of options for each character position: 10 x 9 x 8 x 7 for the digits and multiply by 26 for the final letter, yielding 131,040 unique numbers.

Explanation:

The question asks us to calculate how many unique student numbers are possible with a specific format: the first four characters must be single-digit numbers with no repeat, and the last character must be a letter.

To find the total number of unique student numbers, we multiply the possibilities for each position. For the first position, we have 10 choices (0-9), for the second position 9 choices (excluding the first digit chosen), for the third position 8 choices, and for the fourth position 7 choices. This can be calculated using factorial notation as 10 x 9 x 8 x 7. The last character is a letter and since there are 26 letters in the English alphabet, we have 26 choices for the last character. The total number of combinations is hence 10 x 9 x 8 x 7 x 26, which equals 131,040.

Answer:

The number of adult tickets sold was 300 and that of child's ticket sold is 900.

Step-by-step explanation:

Let us assume that the ticket sales at Wednesday's game are x number adult and y number child's tickets.

Therefore, as per given conditions, we can write, y = 3x .......... (1)

Again, each adult ticket cost $20 and each child's ticket costs $10 and there was a $15000 ticket sale.

So, 20x + 10y = 15000

⇒ 2x + y = 1500 ......... (2)

Now, solving equations (1) and (2) we get,

2x + 3x = 1500

⇒ 5x = 1500

⇒ x = 300 and y = 3x = 900

Therefore, the number of adult tickets sold was 300 and that of child's ticket sold is 900. (Answer)

Answer:

When n=3 and x=−2  the answer is 11.

Step-by-step explanation:

Given:

Let p (n,x) be the function such that

[tex]p (n,x) = n + 2x^{2}[/tex]

To Find:

p (n,x) = p ( 3, -2) = ?

Solution:

[tex]p (n,x) = n + 2x^{2}[/tex]

Substituting n = 3 and x = -2 we get

[tex]p (3, -2) = 3 + 2(-2)^{2}[/tex]

Negative square gives positive number therefore (-2)²=4

[tex]p (3, -2) = 3 + 2\times 4[/tex]

[tex]p (3, -2) = 3 + 8\\p (3, -2) = 11[/tex]

When n=3 and x=−2  the answer is 11.

Final answer:

When evaluating the expression n+2x^2 with n=3 and x=-2, we substitute the values to get 3 + 2(-2)^2, which simplifies to 3 + 8. The final evaluated expression is 11.

Explanation:

To evaluate the expression n+2x² with given values for n and x, we need to substitute the values into the expression and simplify it.

In this case, n = 3 and x = -2. Substituting these values in, we get:

3 + 2(-2)²

First, we calculate the square of -2:

3 + 2(4)

Now, we multiply 2 by 4:

3 + 8

Finally, we add 3 and 8 together:

11

Therefore, the evaluated expression is 11.

3x+12=57

x= how many days

Step-by-step explanation:

Answer:

[tex]3x+12=57[/tex]

Step-by-step explanation:

Let x represent number of days.

We have been given that Marco earns $3 per day working. So amount earned in x days would be [tex]3x[/tex].

We are also told that Marco already has $12 saved, so total amount saved by Marco in x days would be [tex]3x+12[/tex].

Now we will equate total amount saved by Marco in x days with 57 as Marco needs to save $57 to buy new shoes.

[tex]3x+12=57[/tex]

Therefore, the equation [tex]3x+12=57[/tex] shows the number of days (x) that Marco must work before he can afford the shoes.

Answer:

2.5

Step-by-step explanation:

56(t+1/2)=70 t

56T + 28= 70T

28=70T-56T

28=14

2=T

s=T+ 1/2

S=2+ 1/2

S=2.5 hours

Tina traveled for 2 hours at a speed of 70 miles per hour, covering a distance of 140 miles.

Stephanie traveled for 2.5 hours at a speed of 56 miles per hour, also covering a distance of 140 miles.

The distance traveled by a vehicle is given by the formula: distance = speed × time.

For Stephanie:

Distance_stephanie = Speed_stephanie × Time_stephanie

Distance_stephanie = 56 × (t + 0.5)

For Tina:

Distance_tina = Speed_tina × Time_tina

Distance_tina = 70 × t

Since both Stephanie and Tina are traveling the same route, the distances they travel should be equal:

Distance_stephanie = Distance_tina

Substitute the expressions for distances:

56 × (t + 0.5) = 70 × t

Now solve for "t":

56t + 28 = 70t

28 = 14t

t = 28 / 14

t = 2

So, Tina traveled for 2 hours.

Now we can find the distance traveled by both Stephanie and Tina:

Distance_tina = 70 × t

Distance_tina = 70 × 2

Distance_tina = 140 miles

Distance_stephanie = 56 × (t + 0.5)

Distance_stephanie = 56 × (2 + 0.5)

Distance_stephanie = 56 × 2.5

Distance_stephanie = 140 miles

Both Stephanie and Tina traveled a distance of 140 miles.
