Rebecca moves to a large city that had two event stadiums. The larger stadium can hold 4.5 times 10^4 people, which is about 15

NNADVOKAT [17]

Answer:

3,000 people

Step-by-step explanation:

Total number of people larger stadium can hold equals 4.5 times $10^{4}$ people,

which equals 45,000 people.

Now,

it is given that larger stadium can hold 15 times more people than small stadium .

So, smaller stadium will hold 15 times less people than the larger stadium ,

Which equals , $\frac{45000}{15}$ = 3,000 people.

Thus ,

Smaller stadium can hold a total of 3,000 people.

How do I find the variable?<br><br> N x 1/5 = 2/15<br><br> N / 1/5 = 1/3

algol [13]

First you need to get all variables on one side. You do that by multiplying the reciprocal of the fraction to everything.
N(5/1) x 1/5(5/1)=2/15(5/1)
5n=2/15 x 5/1
Then solve the multiplication problem
5n= 10/15
Then you should reduce the fraction
5n=2/3
Then divide both sides by 5
5n/5=N
2/3 divided by 5 =2/15

N=2/15

Write the slope intercept form of the r question of the line parallel to the graph of 2x+y=5 that passes through (0,1)

Fofino [41]

Step-by-step explanation:

first let's get the original line in slope intercept form.

the vegetal slope intercept form is

y = ax + b

a is the slope, b is the y-intercept.

2x + y = 5

y = -2x + 5

there !

a line parallel to this line must have the same slope (-2).

but it will intersect with the y-axis at a different point.

the y-intersect is the y value when x = 0.

the given point (0, 1) is already that y-intersect (because x=0).

so, the desired parallel line function is

y = -2x + 1

if we had a different point of the line, e.g. (4, -7), we would go back to the general equation

y = ax + b

put in the slope we know (-2)

y = -2x + b

and then put in the x and y cakes if the point and calculate b

-7 = -2×4 + b

-7 = -8 + b

b = 1

and then we get again

y = -2x + 1

If a>b, c<b, and d>a, then which of the following is the correct relationship?

tatuchka [14]

x > y is the same like y < x

If a > b and b > c then a > b > c

If d > a then d > a > b > c

<h3>Answer: (D) c < b < a < d</h3>
