Answer:

the two integers are 20 and 60

Step-by-step explanation:

Let x and y be two positive numbers ,where x < y.

• The difference between the two positive numbers x and y is 40.

 Means

y - x = 40

• the ratio of these integers is 1:3

 Means

y = 3x

We obtain these two equations:

y - x = 40

y = 3x

Solving the system of equations by substitution :

y - x = 40

y = 3x

⇔

3x - x = 40

y = 3x

⇔

2x = 40

y = 3x

⇔

x = 20

y = 3 × 20 = 60

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Answer: 15 square Inches

Step-by-step explanation: I believe you should divide 75 and 5(75mi÷5mi=15in) to get 15in.

Answer: 3 square inches.

If the park is 25 square miles, it could be 5×5 miles. If the scale is 1 inch = 5 miles, that would be 1×1 inch or 1 square inch on the map. Since 75 is 3×25, it will be 3×1 square inches on the map.

Step-by-step explanation: Remember that the scale represents linear measurements. For area, you must square the linear "sides" to get the number of actual square units represented by a square unit on the map.

Answer:

(1.5, 4.5 ) and (- 1.5, - 4.5 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

(1.5, - 4.5 ) → (1.5, 4.5 )

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

(1.5, - 4.5 ) → (- 1.5, - 4.5 )

If x- axis then y- axis

(1.5, - 4.5 ) → (1.5, 4.5 ) → (- 1.5, 4.5 )

​Answer:

b=120

Step-by-step explanation:

Solve for b by simplifying both sides of the equation, then isolating the variable.

1) Subtract 3/4b from both sides.

6+ 2/3b− 3/4b = -4

2) Combine 2/3b and -3/4b to get -1/12b

3) Subtract 6 from both sides

6-6-1/12b

4) subtract 6 from -4 to get -10

-1/12b = -10

5) multiply both sides by -12 (the reciprocal of -1/12)

b= -10(-12)

6) multiply -10(-12) to get 120

b=120

Answer:

b=120

Step-by-step explanation:

Solve for b by simplifying both sides of the equation, then isolating the variable.

1) Subtract 3/4b from both sides.

6+ 2/3b− 3/4b = -4

2) Combine 2/3b and -3/4b to get -1/12b

3) Subtract 6 from both sides

6-6-1/12b

4) subtract 6 from -4 to get -10

-1/12b = -10

5) multiply both sides by -12 (the reciprocal of -1/12)

b= -10(-12)

The final answer is:

\(-7 \geq z\)

Step-by-step explanation:

Solve the inequality:

\(-20 \geq z - 13\)

-Add 13 both sides of the equation:

\(-20 +13 \geq z - 13 +13\)

\(-7 \geq z\)

So, the answer is \(-7 \geq z\) .

Answer:

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

See attachment for the graph of the equation.

Step-by-step explanation:

Given equation:

\(y=\dfrac{1}{3}x\)

To complete the table, find the corresponding values of y by substituting each given value of x into the equation.

\(x=6 \implies y=\dfrac{1}{3}(6)=\dfrac{6}{3}=2\)

\(x=12 \implies y=\dfrac{1}{3}(12)=\dfrac{12}{3}=4\)

\(x=18 \implies y=\dfrac{1}{3}(18)=\dfrac{18}{3}=6\)

Therefore the completed table is:

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

Please got brainliest

Reason:

The numerator is \((2.1)^5\)

Raising that to the third power gives

\(((2.1)^5)^3 = (2.1)^{5*3} = (2.1)^{15}\)

We multiply the exponents. The general rule is

\((a^b)^c = a^{b*c}\)

Use that same rule to cube the denominator.

\(((0.9)^4)^3 = (0.9)^{4*3} = (0.9)^{12}\)

Therefore,

\(\left(\frac{(2.1)^5}{(0.9)^4}\right)^3=\frac{((2.1)^5)^3}{((0.9)^4)^3}\\\\=\frac{(2.1)^{5*3}}{(0.9)^{4*3}}\\\\=\frac{(2.1)^{15}}{(0.9)^{12}}\\\\\)

In short

\(\left(\frac{(2.1)^5}{(0.9)^4}\right)^3=\frac{(2.1)^{15}}{(0.9)^{12}}\\\\\)

Answer:

50% chance for a 15% discount

20% chance for a 30% discount

30% chance for a 20% discount

Step-by-step explanation:

On average, each customer can expect to receive a 20.5% discount.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's find the probability of getting each type of discount:

Even number:

There are 5 even numbers between 1 and 10, so the probability of getting an even number is 5/10 = 1/2.

Odd number greater than 6:

There are 3 odd numbers greater than 6 (7, 9, and 10 is not odd), so the probability of getting an odd number greater than 6 is 3/10.

Other:

The remaining 2 odd numbers and the 4 even numbers between 1 and 6 make up the numbers that give a 20% discount.

The probability of getting one of these numbers is 2/10 = 1/5.

Now we can calculate the expected discount:

Expected discount = (probability of getting an even number x discount for even number) + (probability of getting an odd number greater than 6 x discount for odd number greater than 6) + (probability of getting other number x discount for other number)

Expected discount = (1/2 x 15%) + (3/10 x 30%) + (1/5 x 20%)

Expected discount = 7.5% + 9% + 4%

Expected discount = 20.5%

Therefore,

On average, each customer can expect to receive a 20.5% discount.
