Answer:

Beto will reach school first

Step-by-step explanation:

Delia lives 3/4 mile from school, and if she walks at 16 minutes per mile, it would take her

3/4 x 16 = 12 minutes to reach school.

Beto lives 3 1/2 (7/2) miles from school, and if she walks 3 minutes a mile, it would take her

7/2 x 3 = 10.5 minutes to reach school

Answer:

Beto reaches school first

Step-by-step explanation:

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes [tex] \frac{3}{4} \times 16 = [/tex] 12 minutes to reach school.

While Beto lives 3 1/2 miles from school  and bikes at a pace of 3 minutes per mile.

So Beto takes [tex] \frac{7}{2} \times 3 = [/tex] 10.5 minutes to reach school.

Therefore, Beto reaches school first.

Answer:

1/1296

Step-by-step explanation:

Assuming that the probability of rolling a number is the same (1/6), all we have to do it multiply 1/6 by 4 (the number of times you roll the dice).

So 1/6 * 1/6 * 1/6 * 1/6 is just 1/6^4 and 6^4 is 1296.

Therefore the probability of rolling a 6 4 times in a row is 1/1296.

To solve the system of equations using the substitution method, substitute the value of x into the other equation and solve for y.

To solve the system of equations using the substitution method, we first need to solve one of the equations for one variable and then substitute that expression into the other equation. In this case, the second equation is already solved for x, so we can substitute x = 2 into the first equation:

2(2) + 3y = 13
4 + 3y = 13
3y = 9
y = 3

Therefore, the solution to the system of equations is x = 2 and y = 3.

50 individuals bought single tickets and 65 couples bought couple tickets.

Let's define our variables first:

Let [tex]x[/tex] be the number of individuals who bought single tickets.
Let [tex]y[/tex] be the number of couples who bought couple tickets.

From the problem, we have two pieces of information:

We can use these pieces of information to create the following system of equations:

[tex]x + 2y = 180[/tex]

[tex]3x + 5y = 475[/tex]

First, solve equation 1 for [tex]x[/tex]:

[tex]x = 180 - 2y[/tex]

Now, substitute this expression for [tex]x[/tex] in equation 2:

[tex]3(180 - 2y) + 5y = 475[/tex]

Simplify and solve for [tex]y[/tex]:

[tex]540 - 6y + 5y = 475[/tex]

[tex]540 - y = 475[/tex]

[tex]-y = 475 - 540[/tex]

[tex]-y = -65[/tex]

[tex]y = 65[/tex]

So there were 65 couples at the dance.

To find the number of individuals who bought single tickets, substitute [tex]y[/tex] back into the expression for [tex]x[/tex]:

[tex]x = 180 - 2(65)[/tex]

[tex]x = 180 - 130[/tex]

[tex]x = 50[/tex]

Answer: " 200 % . "  

___________________________________________________

          " 20 " is:  " 200 % " of:  "40 ."

___________________________________________________

Step-by-step explanation:

___________________________________________________

(n/100) * 20 = 40 ;   Solve for "n" ;

Note that:  percent =  per "100" ;  thus "(n/100)" ;

Divide each side of the equation by:  "20" :

(n/100) * 20 ÷ 20 = 40 ÷ 20 ;

to get:

(n/100) = 2 ;  

Multiply each side of the equation by "100" ; to get rid of the "fraction" ;

          and to isolate "n"  on one side of the equation ;

          and to solve for "n" ;

(n/100) * 100 = 2 * 100 ;

to get:

n = 200 ;

The answer is:  200 % .

There is 200% of number 20 is, 40

Since, A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

We can assume that,

x% of 20 is, 40

Hence, We can formulate;

⇒ x% of 20 = 40

Solve for x;

⇒ x/100 × 20 = 40

⇒ x / 5 = 40

⇒ x = 40 × 5

⇒ x = 200

Thus, There is 200% of number 20 is, 40

Answer: Less than

Without actually solving this, we can find that the product of 3 and 4/5 will be less than 3. The reason for this is because 4/5 < 1. If we simply would do 3 * 1 we would just get 3. But since we are multiplying it by a number smaller than 1, we will be getting a number less than 3.

Solving this:

4/5 = 0.8

3 * 0.8 = 2.4

Answer:

Its graph A on edge. Just took it!

Step-by-step explanation:

The graph that represents the inequality |x + 1| + 2 < –1 is at option 1. Since the equation has no solution (empty set), the graph does not get intersected.

The inequality equation is the one that is true for some values of the variable. The inequalities may be greater than, less than, greater than or equal, or less than or equal.

The given inequality equation is

|x + 1| + 2 < –1

⇒ |x + 1| +2 - 2 < –1 -2

⇒ |x + 1|  < –3

So, (x+1) < -3 or (x+1) > -3

⇒ x < -4 or x > -4

This is not possible. So the solution set of the given inequality is empty.

So, the graph is shown for different expressions.

The expressions are considered as

f(x) = |x + 1| + 2 and y < -1

In option 1, the graph shows these two expressions. So, the correct representation for the given inequality is option 1.

Since there is no solution, they do not have any intersecting points in the graph.

C. [tex]F(x)=2^{x}-1[/tex]

In order to find the correct option, we need to substitute/evaluate the given values of "x" into each function.

Substituting into the first equation, option A:

[tex]F(x)=3^{x} \\F(3)=3^{3}=27\\F(3)=3^{4}=81[/tex]

... and so.

We can see that the option A is not the correct option since the obtained values do not match with the given values.

Substituting into the second equation, option B:

[tex]F(x)=3x\\F(3)=3*3=9\\F(4)=3*4=12\\[/tex]

... and so.

We can see that the values obtained from the function do not match with the given values, so the option B is not correct.

Substituting into the third equation, option C:

[tex]F(x)=2^{x}-1\\F(3)=2^{3}-1=8-1=7\\F(4)=2^{4}-1=16-1=15\\F(5)=2^{5}-1=32-1=31\\F(7)=2^{7}-1=128-1=127\\F(8)=2^{8}-1=256-1=255\\[/tex]

So, since all the obtained values match with the given values, we can conclude that the correct option is the option C.
