Answer:

6 gallons   54 fish

Step-by-step explanation:

is she has 12 gallons and in 2 minutes its gone at a steady rate then just divide 12 by 2 so 6 every minute

just 3 multiplied by 18 since hes adding 3 fish every day for 18 days so you could just do 3+3+3+3 for 18 or simpler 3x18

Answer:

D. (x-3)(x^2 + 4x - 5)

Step-by-step explanation:

P(x) = x³ + x² - 17x + 15 can be written as (x - 3) (x² + 4x - 5) as a product of two factors.

Polynomials are expressions in algebra which consist of variables, constants and exponents combined using the basic operations in mathematics like addition, subtraction, multiplication and division.

Polynomials can be classified as monomials, binomials and trinomials depending on the degree of the variables as 1, 2 and 3 respectively.

The given polynomial is P(x) = x³ + x² - 17x + 15.

We already have x - 3 is the factor of this polynomial.

To get the other factor which is a binomial, we have to divide the given polynomial with x - 3.

On dividing, we get x² + 4x - 5 as the quotient and remainder equals zero.

So x² + 4x - 5 is the other factor of the given polynomial.

Hence, the polynomial P(x) = x³ + x² - 17x + 15 can be written as (x - 3) (x² + 4x - 5) as a product of two factors.

Answer:

Joe's rate = 7 mph

Ralph's rate = 8 mph

Step-by-step explanation:

Give. That:

Joe's rate = x

Ralph rate = x + 1 kmph

Travel time = 2 hours

Hence, distance traveled = Speed * time

Joe's distance : 2 * x

Ralph's distance = 2 * (x + 1)

2x + 2(x + 1) = 30

2x + 2x + 2 = 30

4x + 2 = 30

4x = 30 - 2

4x = 28

x = 28/4

x = 7

Joe's rate = 7

Ralph's rate = 7 + 1 = 8

Answer:

The ratio of apples to oranges in the basket is 2:5.

Step-by-step explanation:

the answer is D

Step-by-step explanation:

Total fruit (apples + oranges ) = 125

only oranges = 7/25 of total fruit = (7/25)× 125

7×5= 35 (orange)

then only apples = 125 - 35 = 90

Answer:

[tex]\textsf{C.} \quad C = \$10 + \$5h[/tex]

Step-by-step explanation:

Given information:

Given variables:

The Park admission fee of $10 is independent of the fee charged per hour per sport.  Therefore, it is represented by a constant in the equation.

The fee per hour of sledding is dependent on the number of hours spent.  Therefore, it is represented by the cost of the specific sport multiplied by the given variable for time (h).

Therefore the equation that represents the cost of sledding per hour is:

C = $10 + $5h

[tex]\huge \boxed{\sf C}[/tex]

Each hour costs 5 dollars for sledding and an extra fee of 10 dollars.

[tex]\sf C = 5h + 10[/tex]

An equation contains variables and integers.

C and h are variables which means the value changes.

5 and 10 are integers.

Answer:

Monthly deposit= $262.062

Step-by-step explanation:

Giving the following information:

Future value= $10,000

Number of periods= 12*3= 36 months

Interest rate= 0.04/12= 0.0033

To calculate the monthly deposit, we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (10,000*0.0033) / [(1.0033^36) - 1]

A= $262.062

Answer:

√3/2

Step-by-step explanation:

We are to find the exact value of the expression below

Cos(Tan^- 1 - (sqrt(3))/3)

Evaluate the one in bracket first

Tan^-1√3/3 = 30°

Cos(Tan^- 1 (sqrt(3))/3) = Cos30°

Now find cos30°

cos30° = √3/2

Hence the value for the trigonometric expression is √3/2

=============================================

Explanation:

If you graphed the equation 2x-5y = 14, you'll find it has a positive slope. It turns out the slope in this equation is 2/5, which is positive. A positive slope means the line goes uphill as you move from left to right. This means we can rule out choice because of this (since we want the line to slope downward).

Now let's turn to choice D. If we multiply both sides of the first inequality by -1, then we go from [tex]-2x-5y \le 14[/tex] to [tex]2x+5y \ge -14[/tex]. Note the inequality sign flips. This always happens when we multiply both sides by any negative number. The inequality [tex]2x+5y \ge -14[/tex] implies that the shaded region will be above the boundary line, but this contradicts the drawing which shows the shaded region is below the diagonal boundary line. We can rule out choice D because of this. Choice A can be ruled out for similar reasoning.

You should find that only choice B is left. The diagonal line is 2x+5y = 14, and we shade below this boundary line, as well as shading to the right of the y axis (to indicate all values have positive x coordinates). Values on the boundary count as solution points as well.

Answer:

24 pictures for $5

Step-by-step explanation:

To find out the better value, we have to find the price of a singular picture. To do this, we will divide each number by the amount of pictures.

For the first deal, 36 pictures cost $8, so 1 picture costs about $0.22.

For the second deal, 24 pictures cost $5, so 1 picture costs about $0.21.

Since the second deal costs less, it is a better deal.

Answer:

The best deal is 24 pictures for $5.

Step-by-step explanation:

In order to find out which price is better, we need to find the amount of pictures per dollar. This is also known as the unit rate.

36 ÷ 8 = 4.5 or 5 when rounded to the nearest whole number.

24 ÷ 5 = 4.8 or 5 when rounded to the nearest whole number.

However, since 4.8 is in fact higher than 4.5, the best deal is 24 pictures for $5.

the estimation of the quotient is  7

Step-by-step explanation:

The computation of estimating the quotient is shown below:

It is given that the number is 27

After that the two-third would be divided by 3

And, then the nine-tenth

Based on the above information, the estimation of the quotient is  

= 27 + 2 ÷ 3 ÷ 3 + 9 ÷ 10

= 27 + 0.67 ÷ 3 + 0.9

Step-by-step explanation:

x = ky, where k is a real constant.

When y = 36, x = 24.

=> (24) = k(36), k = 2/3.

Hence x = (2/3)y.

When y = 132, x = (2/3)(132) = 88.

Answer:

see explanation

Step-by-step explanation:

Given x varies directly with y then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 24 when y = 36, then

36 = 24k ( divide both sides by 24 )

1.5 = k

y = 1.5x ← equation of variation

When y = 132, then

132 = 1.5x ( divide both sides by 1.5 )

x = 88
