Answer:

There's 9 nickels and no dimes

Step-by-step explanation:

the quarters equal $2.25

so there is at least 9 nickel's witch equals .45 cents add them and get $2.70 so

The system of equations to find the number of quarters, 9, dim, d, and nickels, n, that Gabby has are;

Since, the total value of quarters, dim, and nicke is; $2.70.

Since the number of nickels that she has is equal to the number of quarters plus the number of dimes; we have;

Since, Gabby has 20 coins in her pocket.

Therefore 2n = 20 from n = q + d

Inequality :

α1+(n−1)a−(⌊n÷m⌋×(a−b))≥x

The following is as far as I get:

α1+(n−1)a−(⌊n÷m⌋×(a−b))≥x

(n−1)a−(⌊n÷m⌋×(a−b))≥x−α1

n−1−(⌊n÷m⌋×(a−b))≥x−α1a

n−(⌊n÷m⌋×(a−b))≥x−α1a + 1

Answer: “samuel earns $20 for each lawn he mows”

Step-by-step explanation:

The statements that represent proportional relationship are statement [1], [2] and [4].

        y = mx + c

        for [c] = 0

        m = y/x

        where [m] is the constant of proportionality.

Given are some statements depicting proportional relationship.

For the statement [1], we can write the equation as -

y = 0.08x + 59

For the statement [2], we can write the equation as -

y = 25x + 45

For the statement [1], we can write the equation as -

y = 20x

Therefore, the statements that represent proportional relationship are statement [1], [2] and [4].

Answer:

-1

Step-by-step explanation:

This is the slope because x is the slope, and if there is no number in front of x then x is 1. There is also a negative in front of x which means the answer is -1.  

The slope of the equation y = -x + 7 equals -1.

Answer:

10 % of the total time will be saved on the new route with the new speed.

Step-by-step explanation:

Let x miles  be the old route. Then the new route would be 1.26 x miles

Let y be the speed on the old route . Then the speed on the new route would be 1.4 y .

And let t be the time on the old route

Speed = Distance / Time

or

Time = Distance / Speed

t= x/y

     Time for the new route   = 1.26x/ 1.4y= 0.9 t

0.9 t means 90% of the old time will be required to cover 1.26x  miles with 1.4 y speed.

And 10 % of the total time will be saved on the new route with the new speed.

Answer:

133 feet²

Step-by-step explanation:

To find the area of a shape you need to use the the formula "length(L) times(×) width(W)". In this problem it gives you both the length and width which means you just need to multiply the two numbers to get your answer. (You need to add feet because that's what is being used in the problem and ²(squared) because area is measured in square units.

Step-by-step explanation:

Given that,

Thomas's time is 8 seconds more than Mia's time.

Jasmine's time is į times the quantity of 21 seconds more than Mia's time

The sum of all three times is 71 seconds.

To find,

The value of m.

Solution,

Let Mia's time is m.

Thomas's time = 8+m

Jasmine's time = 21 + 8+ m

ATQ,

m + 8 + m + 21 + 8 + m = 71

3m + 37 = 71

3 m = 71 - 37

m = 34/3

m = 11.34

So, the value of m or Mia's time is 11.34 seconds.

Answer:

m+1/3(m+21)+m+8=71, m=24

Answer:

[tex]\bold{\frac{1}{6}}[/tex] of the bottle was used

Step-by-step explanation:

Amount of cleaning solution present in spray bottle = [tex]\frac{2}3[/tex] of the bottle

Amount of cleaning solution present in the spray bottle used = [tex]\frac{1}4[/tex] of the cleaning solution present initially

To find:

How much of the bottle was used?

Solution:

Here, we need to find how much amount of the cleaning solution spray was used from the complete bottle.

Amount of spray used = [tex]\frac{1}{4}\times \frac{2}{3}[/tex] of the cleaning solution = [tex]\bold{\frac{1}{6}}[/tex] of the cleaning solution.

Therefore, the answer is:

[tex]\bold{\frac{1}{6}}[/tex] of the bottle was used
