Final answer:

To decide the better purchase between two sizes of shampoo, the cost per ounce is calculated, showing that the 18oz option at $0.22 per ounce is more economical than the 24oz option at $0.25 per ounce.

Explanation:

To determine which shampoo option is the better buy, we calculate the cost per ounce for each option. Cost per ounce is calculated by dividing the total cost of the product by the total number of ounces.

For the 18oz shampoo at $3.99, cost per ounce = $3.99 / 18oz = $0.22 per ounce.

For the 24oz shampoo at $5.99, cost per ounce = $5.99 / 24oz = $0.25 per ounce.

The 18oz shampoo at $0.22 per ounce is the better buy compared to the 24oz shampoo at $0.25 per ounce because you are paying less per ounce.

Answer:

Option 4

Step-by-step explanation:

Given : d to the 7th power times g to the 13th power all over d to the 2nd power times g to the 7th power.

To find : The correct  simplification

Solution :

d to the 7th power = [tex]d^7[/tex]

g to the 13th power = [tex]g^{13}[/tex]

d to the 7th power times g to the 13th power =  [tex]d^7\times g^{13}[/tex]

d to the 2nd power = [tex]d^2[/tex]

g to the 7th power = [tex]g^7[/tex]

d to the 2nd power times g to the 7th power =  [tex]d^2\times g^{7}[/tex]

According to question,

d to the 7th power times g to the 13th power all over d to the 2nd power times g to the 7th power.

[tex]=\frac{d^7\times g^{13}}{d^2\times g^7}[/tex]

[tex]=d^{7-2}\times g^{13-7}[/tex]

[tex]=d^{5}\times g^{6}[/tex]

Therefore, Option 4 is correct.

Given is a square pyramid with a base length of 5 centimeters and a height of 6 centimeters.

The volume formula of square pyramid is given by :-

[tex] volume = \frac{1}{3} (base\; area)(height) [/tex]

Base area would be a square of side length equal to 5 centimeters.

Area of square = (side)² = 5 × 5 = 25 squared centimeters.

Now, volume of square pyramid = [tex] \frac{1}{3} (25)(6) [/tex] = 50 cubic centimeters.

So, final answer is 50 cubic centimeters.

The easiest option will definitely be:

x = 5 and y = y

Happy homework/ study/ exam!

we know that

the equation of the line in the form point-slope is equal to

[tex]y-y1=m*(x-x1)[/tex]

in this problem we have

[tex]point(4,-1)\\\\m=\frac{3}{2}[/tex]

Substitute the values

[tex]y+1=\frac{3}{2}*(x-4)[/tex]

[tex]y=\frac{3}{2}x-6-1\\\\y=\frac{3}{2}x-7[/tex]

therefore

the answer is

[tex]y=\frac{3}{2}x-7[/tex]

1. The value of x is 3.96

2. The value of x is 3.75

Similar triangles are triangles with equal corresponding side ratios and equal corresponding angles.

For two triangles to be Similar, the ratio of their corresponding sides must be equal.

Using similar triangles theorem;

1. x /6 = 3.3/5

5x = 19.8

x = 3.96

2. x/1.5 = 10/4

4x = 1.5 × 10

4x = 15

x = 15/4

x = 3.75

Answer: 120 people like brand A better

Step-by-step explanation:

Final answer:

By setting up an equation based on the given ratio 2:5 and the additional information that Julie receives £45 more than Pat, we find that Pat received £30.

Explanation:

The question deals with understanding ratios and how they can be used to solve problems involving sharing amounts in specified proportions. Pat and Julie share some money in the ratio 2:5, and it's given that Julie gets £45 more than Pat. To approach this problem, let's designate the amount Pat receives as 2x and the amount Julie receives as 5x, where x is a common multiplier.

It is stated that Julie gets £45 more than Pat, which can be represented as 5x = 2x + 45.

Solving the equation for x gives us 3x = 45, hence x = 15.

To find out how much Pat received, we substitute x = 15 into 2x, giving us 2(15) = 30.

Therefore, Pat got £30.

There were [tex]\(38\)[/tex] votes for blue and [tex]\(13\)[/tex] votes for green.

Let's break it down step by step:

1. Votes for Blue:

  Initially, [tex]\(5/8\)[/tex] of the votes were for blue. Let's denote the total number of votes as [tex]\(T\).[/tex]

  So, the number of votes for blue initially is [tex]\(5/8\) of \(T\)[/tex], which is [tex]\((5/8) \times T\)[/tex].

2. Remaining votes after blue:

  After blue votes are accounted for, the remaining votes are [tex]\(T - (5/8) \times T = (3/8) \times T\).[/tex]

3. Votes for Green:

  [tex]\(5/9\)[/tex] of the remaining votes are for green. So, the number of votes for green is [tex]\((5/9) \times (3/8) \times T\)[/tex].

4. Votes for Red:

  The remaining votes after blue and green are accounted for are 48 votes.

To find the solution, we need to set up equations based on the information given:

Equation 1: Votes for blue + Votes for green + Votes for red = Total votes

Equation 2: Votes for green = \(5/9\) of remaining votes

Equation 3: Votes for red = 48

Let's solve these equations:

Equation 1:

[tex]\[\frac{5}{8}T + \frac{5}{9} \times \frac{3}{8}T + 48 = T\][/tex]

Equation 2:

[tex]\[\frac{5}{9} \times \frac{3}{8}T = \frac{15}{72}T = \frac{5}{24}T\][/tex]

Now, let's substitute the value of [tex]\(T\)[/tex] from Equation 3 into Equation 1:

[tex]\[\frac{5}{8} \times \frac{48}{5} + \frac{5}{9} \times \frac{3}{8} \times \frac{48}{5} + 48 = \frac{48}{8} + \frac{15}{24} \times \frac{48}{5} + 48 = 6 + 3 \times 2 + 48 = 60\][/tex]

So, we have [tex]\(T = 60\).[/tex]

Now, let's find the number of votes for blue and green:

Votes for blue:

[tex]\[\frac{5}{8} \times 60 = 37.5\][/tex]

Votes for green:

[tex]\[\frac{5}{24} \times 60 = 12.5\][/tex]

Since we can't have half votes, we round 37.5 to 38 and 12.5 to 13.

So, there were [tex]\(38\)[/tex] votes for blue and [tex]\(13\)[/tex] votes for green.

The correct question is:

5/8 of the votes were for blue. 5/9 of the remaining votes were for green and the remaining 48 votes were for red. How many votes were for blue? How many votes were for green?
