The equivalent fraction of 8/9 with the denominator 18 is 16/18.

To write the fraction 8/9 as an equivalent fraction with the given denominator 18, we have to find a number that we multiply by 9 (the original denominator) to get 18. This number, in this case, is 2. What we do to the bottom of a fraction, we should also do to the top, therefore we would also multiply the numerator (8) by the same number (2). So, the equivalent fraction is 8 * 2 / 9 * 2 = 16 / 18.

By using algebra to model the problem, we find that the pharmacist had 36 prescriptions for tranquilizers.

In the given problem, we need to find out the number of prescriptions for tranquilizers. We know that the pharmacist has 4/3 as many prescriptions for antibiotics as tranquilizers. We also know that the total number of prescriptions for both the drugs is 84. We can make a mathematical model out of this information and solve for the number of tranquilizer prescriptions.

Let us suppose the number of tranquilizer prescriptions is x. Then the number of antibiotic prescriptions would be 4/3*x. Together, these prescriptions add up to 84.

So, we can write the equation: x + 4/3*x = 84

To make the equation simpler we can multiply the entire equation by 3 which transforms the equation into: 3x + 4x = 252

Combining like terms gives us: 7x = 252

Finally, dividing both sides of the equation by 7 gives us the solution: x = 252 / 7

So, x = 36

Therefore, we conclude that the pharmacist had 36 prescriptions for tranquilizers.

The value of y is 1.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

Let's simplify the left-hand side first:

4y - 7 + 2y = 6y - 7

Now let's simplify the right-hand side:

-3(y - 1) - 1 = -3y + 2

Now we can substitute these simplified expressions back into the original equation and solve for y:

6y - 7 = -3y + 2

Adding 3y to both sides, we get:

9y - 7 = 2

Adding 7 to both sides, we get:

9y = 9

Dividing both sides by 9, we get:

y = 1

Therefore, the solution is y = 1.

Answer:

810 feet.

Step-by-step explanation:

We are supposed to find the final altitude of the helicopter.

We have been given that a helicopter is flying at a altitude of 785 feet, this means that altitude of helicopter is positive.

Further, the helicopter descends 570 feet, this means that altitude of helicopter is [tex]-570[/tex].

Finally, the helicopter ascends 595 feet, this means that altitude of helicopter is [tex]595[/tex].

[tex]\text{Helicopter's final elevation}=785\text{ ft}-570\text{ ft}+595\text{ ft}[/tex]

[tex]\text{Helicopter's final elevation}=810\text{ ft}[/tex]

Therefore, the final elevation of helicopter is 810 feet.

The student is asking about fractions. In a fraction, the denominator (bottom number) represents the total number of equal parts the whole is divided into, while the numerator (top number) signifies the parts we're considering. When multiplying, the numerators and denominators multiply separately to form the new fraction.

The student is referring to the concept of fractions. In a fraction, the number on the bottom (the denominator) is the total number of equal parts into which a whole is divided, and the number on the top (the numerator) is the number of those parts we are considering. To clarify by using an example, let’s take 2/4. In this scenario, the denominator is 4, which means our whole is divided into 4 equal parts. The numerator is 2, which shows that we're referring to 2 out of those 4 parts. When multiplying fraction, the numerators multiply to create the new numerator and denominators multiply to create the new denominator. Hence, 2/4 multiplied with 3/4 would produce 6/16.

Final answer:

To find the perimeter of Jill's room in the scale drawing, convert the actual room measurements using the scale and then calculate the perimeter based on the scaled dimensions. The perimeter on the drawing is 12 inches.

Explanation:

The question asks us to calculate the perimeter of a room in a scale drawing. Jill's room measurements are 12.5 feet in length and 11.5 feet in width, with a scale of 0.5 inch equals 2 feet. To find the perimeter on the drawing, we first convert the actual measurements into scale measurements:

Scale for Length: 12.5 feet / 2 feet = 6.25; then 6.25 × 0.5 inch = 3.125 inches.

Scale for Width: 11.5 feet / 2 feet = 5.75; then 5.75 × 0.5 inch = 2.875 inches.

Next, we calculate the perimeter of Jill's room on the drawing:

Perimeter = 2 × (Length + Width) in the drawing.

Perimeter = 2 × (3.125 inches + 2.875 inches) = 2 × 6 inches = 12 inches.

Therefore, the perimeter of Jill's room on the drawing is 12 inches.

Answer:

Cost:$ 920 each or $5,520

Total annual interest: $65 per bond and $390 total

Yield: 7.06%

Step-by-step explanation:

The cost of the bonds is given by the multiplication of the value of the bonds by 92 and divided by 100:

1000*92/100=920

So the cost of each bond would be $920

Then the interest that is payed by the bonds is based on its value which is $1000, so he receives 65 dollars per bond a year, that multiplied by the 6 bonds is equal to $390.

The yield is the real money paid to return interest rate relation, so you just have to take the percentage if 5,520 is the 100, how much is $390=

5520/100=390/x

x=39000/5520=7.06%

Using the concept of similar triangles to calculate the scale factor, the height of the streetlight is 3 times the height of the person.

Length of shadow cast = 10 feets

Height of person = 6 feets

Distance of person from streetlight light = 20 feets

Since the triangles are similar :

Comparing the length of both triangles :

The scale factor is :

Using the scale factor ; the height of the streetlight will be :

Height of streetlight = 18 feets

The coat would cost $0.60 more in Delaware County than in Fairfield County.

To determine how much more the coat would cost in Delaware County compared to Fairfield County, we need to calculate the total cost of the coat in both counties, including their respective sales tax rates, and then find the difference between these two amounts.

First, let's calculate the total cost of the coat in Delaware County:

1. Original price of the coat: $80

2. Sales tax rate in Delaware County: 7.25%

The sales tax amount in Delaware County is calculated as:

[tex]\[\text{Sales tax} = \text{Original price} \times \left(\frac{\text{Sales tax rate}}{100}\right) = 80 \times \left(\frac{7.25}{100}\right) = 80 \times 0.0725 = 5.80\][/tex]

So, the total cost in Delaware County is:[tex]\[\text{Total cost} = \text{Original price} + \text{Sales tax} = 80 + 5.80 = 85.80\][/tex]

The sales tax amount in Fairfield County is calculated as:

[tex]\[\text{Sales tax} = \text{Original price} \times \left(\frac{\text{Sales tax rate}}{100}\right) = 80 \times \left(\frac{6.5}{100}\right) = 80 \times 0.065 = 5.20\][/tex]

So, the total cost in Fairfield County is:

[tex]\[\text{Total cost} = \text{Original price} + \text{Sales tax} = 80 + 5.20 = 85.20\][/tex]

Now, let's find the difference in total costs between Delaware County and Fairfield County:

[tex]\[\text{Difference} = \text{Total cost in Delaware County} - \text{Total cost in Fairfield County} = 85.80 - 85.20 = 0.60\][/tex]
