Hamburger costs $1.50 per pound and soy costs $1.00 per pound. The school cafeteria uses 50 more pounds of soy than hamburger and spends $350 a week. How much soy does the school use?

Answers

Answer 1

Suppose the the school uses x pounds of Hamburger, then the number of pounds of soy is x+50, the cost of Hamburger is 1.50x, the cost of soy is 1.00(x+50), the total cost if 350
1.50x +1.00(x+50)=350
2.50x+50=350
2.50x=300
x=120
120+50=170
so the school uses 120 pounds of Hamburger and 170 pounds of soy

on a shopping trip gill spends 1/3rd of his money in store A then he spends 1/3 of money he has left in store B. Finally he spends his remaining $12 in store C. How many dollars did he have at the start?

Answers

Answer:

$18

Step-by-step explanation:

Let the money he had at the start be $x

Store A = 1/3 of $x = $ x/3

Remaining = $ x/1 - $x/3 = $ 2x/3

He spends remaining $12. So,

2x/3 = 12

2x = 36

10. Rosa received a monthly raise of $162.50. If this represented a 6.5% increase, what is her monthly salary after the raise?

Answers

$187.05 because you divide her raise by the percent increase and you get 25. So then you add 25 to 162.50

Answer:

$137.5

Step-by-step explanation:

First, you need to divide $162.50 by 6.5

If you divide correctly you should get 25

Since that month she got an increase, which means you have to subtract 25 from $162.50.

Answer: $137.5

Can someone explain to me how to solve this/these types of problems? Don't just answer it, explain.

Answers

The easiest method to solve problems like this is to graph the inequalities given and shade the regions that make them true. When you have properly shaded all of the regions, you will find that you have a region which is bounded on all four sides by one of the inequalities, and then you can find the x and y values which correspond to the vertices of the shaded region.

You didn't provide a function that you are trying to maximize in this example, but the idea is that you take all of the (x,y) points which correspond to the vertices and plug them into your objective function. The one which produces the largest value maximizes it (it is a similar process for minimizing it, but you'd be looking for the smallest value). Let me know if you need more help than that, or would like me to work out the example you have provided (I will need an objective function for it though).

What property did Ramon use? 150+214+89=214+89+150

Answers

This is the communicative property. This means you just move the numbers around, but the result will be he same as long as you’re ADDING

Final answer:

Ramon used the Commutative Property of Addition in the equation 150+214+89=214+89+150. This property indicates that the order in which numbers are added doesn't affect the result.

Explanation:

In the given equation, 150+214+89=214+89+150, Ramon is using an important property of addition known as the Commutative Property. The Commutative Property of Addition states that the order in which numbers are added does not change the sum. For example, if we have two numbers, 5 and 3, adding them in any order (5+3 or 3+5) will always give us the same result, which is 8. Hence, in this question, whether you add 150, 214 and 89 in the given order or reverse, the sum remains the same. Therefore, you can see how Ramon made use of the Commutative Property to rearrange the numbers while still keeping the total sum the same.

The volume of 1000 drops of a liquid is 0.1 fluid ounce.
What is the volume of 10,000 drops?

Answers

1 fluid ounce

1000= 0.1

when you add zeros you move the decimal point over to the left making it

10,000= 1fluid ounce

Final answer:

To find the volume of 10,000 drops, if 1000 drops equal 0.1 fluid ounce, we multiply the volume by 10 to get 1.0 fluid ounce.

Explanation:

The volume of 10,000 drops of a liquid, when 1000 drops is equivalent to 0.1 fluid ounce, can be calculated using a simple ratio. If 1000 drops equal 0.1 fluid ounce, then we can multiply both the number of drops and the volume by 10 to find the volume of 10,000 drops:

1000 drops = 0.1 fluid ounce

10,000 drops = 1.0 fluid ounce (since 0.1 fluid ounce x 10 = 1.0 fluid ounce)

Therefore, the volume of 10,000 drops is 1.0 fluid ounce.

A group of fans at a football game are sitting in 7 rows with 28 in each row. In the center, a section of 14 fans in 3 rows and a section of 11 fans in 3 rows have cards spelling out the team name. How many fans do not have a card?

Answers

I believe it would be 75.
I hope this helps

Final answer:

Out of 196 fans, 75 fans have cards. Therefore, 121 fans do not have a card.

Explanation:

The question is asking how many fans do not have a card at a football game. Initially, there are 7 rows of fans with 28 fans in each row, which gives us 196 fans in total (7 * 28). In the center, there are two sections where fans have cards. The first section has 14 fans in 3 rows, which equates to 42 fans (14 * 3), and the second section consists of 11 fans in 3 rows, which makes 33 fans (11 * 3). So, the total number of fans with cards is 75 (42 + 33). To find out how many fans do not have a card, we subtract the number of fans with cards from the total number of fans. Therefore, the answer is 196 - 75 = 121 fans.

A funnel is made up of a partial cone and a cylinder as shown in the figure. The maximum amount of liquid that can be in the funnel at any given time is 16.59375 cubic centimeters. Given this information, what is the volume of the partial cone that makes up the top part of the funnel?

Answers

The volume of the partial cone is the volume of the entire funnel minus the volume of the cylindrical part.

The volume of a cylinder is given by:

[tex]V=\pi r^2h[/tex]
where: r is the radius of the cylinder and h is the height of the cylinder.

Given that the cylindrical part of the funnel has a height of 1.5 cm and a diameter of 1.5 cm, thus the radius is 1.5 / 2 = 0.75 cm and the volume is given by:

[tex]V=\pi(0.75)^2(1.5)=0.84375\pi=2.65072cm^3[/tex]

Therefore, the volume of the partial cone is given by 16.59375 - 2.65072 = 13.94303 cubic cm.
