two years ago the cats tim and tom were toghether 15 years old.Now tom is 13 years old.In how many years will tim be 9 years old?

Answers

Answer 1

Answer:

  3 years

Step-by-step explanation:

As with many age problems, you can reason it without equations. If Tom is 13 now, 2 years ago he was 11. If the total age of the two cats at that time was 15, then Tim was 15 -11 = 4.

That means Tim is now 4+2 = 6, so will be 9 in 3 years.

_____

Additional comment

If you want to write equations, there are several ways you can do it. We often like to use variables to represent the current age. We can assign ...

  x = Tim's current age; y = Tom's current age.

The sum of their ages 2 years ago was ...

  (x -2) +(y -2) = 15

Tom's current age is 13, so we have y=13. Using that in the equation gives ...

  x -2 +13 -2 = 15

  x = 6 . . . . . . . . . . subtract 9, collect terms

That's Tim's current age, so Tim will be 9 years old in 3 years.

1. Mrs. Galicia is building a chicken farm in 2021 with an initial population of 3750 chickens. The farm grows at a rate of 2.15% annually.
(a) Use the exponential growth model to write an equation that estimates the population t years after 2021.
(b) Estimate the population of the town in 2036. *please show plug in step*

Answers

Hey there!

a) --›initial number = 3750

--›rate = 2.5%

let y be the population t years after 2021

So, y = 3750(1+2.15) ^ t

=> 3750 × 1.0215 ^ t

b) In 2036,

=> t = 2036 - 2021

=> 15

Substitute into the first value

=> 3750 × 1.0215 ^ t

=> 3750 × 1.0215 ^ 15

=> 5159.

Therefore, the population in 2036 would be 5159

Answer:

407,102 meters

Step-by-step explanation:

Convert the kilometers to meters.

394 km x 1000 = 394000 meters

13 km x 1000 = 13000 meters

Add the results together.

407,000

Find X and Y please !

Answers

Answer:

So first we need to find y, to do that we make an equation.
3y-12+63=180, first add 63 to -12.
3y+51=180, we move our constant to the right.
3y=180-51, subtract 51 from 180
3y=129, divide both sides by 3.
3y/3=129/3, and your answer is...
y=43

Now to find x, so we know that both the top and bottom lines are the same since they are cut into equal angles by the vertical line. To make this easier let’s do the math knowing that y=43, 3(43)-12=117. This means that the top right angle on the top line equals 177 degrees. And if you invert the angles that means the bottom left angle of the top line equals 177. Now we know what 5x+2 will equal however we still need to find x, before we make an equation we also need to be aware that the top left angle on the top line is also 63 degrees, by inverting that we also know the bottom right angle of the top line equals 63 degrees. So now we make our equation to find x.

5x+2+63=180, first we add 2 to 63.
5x+65=180, then we move our constant to the right.
5x=180-65, subtract 65 from 180.
5x=115, divide both sides by 5.
5x/5=115/5, and your answer is...
x=23

Angles A and B are complementary to each other. If mA = 130 + x and mB = 170 + x, what is the value of x?∠∠

Answers

Answer:

-105

Step-by-step explanation:

This means their measures add to 90 degrees, so:

(130+x)+(170+x)=90

300+2x=90

2x=-210

x=-105

The value of x in the expression for the measure of the complementary angle is -105.

What is the numerical value of x?

Complementary angles are simply angles that sum up to 90 degrees.

Given the parameter:

Angles A and B are complementary.

Measure of angle A = 130 + x

Measure of angle B = 170 + x

Value of x =?

Since angles A and B are complementary, their sum should be equal to 90 degrees.

Hence:

Angles A + Angle B = 90

Plug in the expressions:

(130 + x) + (170 + x) = 90

Combine like terms:

x + x + 130 + 170

2x + 300 = 90

Subtract 300 from both sides:

2x + 300 - 300 = 90 - 300

2x = -210

x = -210/2

x = -105

Therefore, x has a value of -105.

Assume that based on 2,000 calories per day, you want to choose 1/8 of your daily calories from consuming milk. How many calories am I allowed to get from milk and how many cups per serving?(1 cup of milk has 150 calories)

Answers

Answer:

1.7 cups

Step-by-step explanation:

Firstly, we need to figure out how many calories of milk we are allowed to consume. This would be solved by dividing 2000 by 8 to find 1/8 of 2000.2000 ÷ 8 is 250 calories. With this information, now we can use the information we have about one cup of milk.If one cup of milk is 150 calories and we are allowed to consume 250 calories of milk, we can solve by dividing 250 by 150.250 ÷ 150 is 1.7 cups of milk.

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 60 pounds. The truck is transporting 70 large boxes and 60 small boxes. If the truck is carrying a total of 4000 pounds in boxes, how much does each type of box weigh?

Answers

Answer:

large: 40 lbssmall: 20 lbs

Step-by-step explanation:

A system of equations can be written for the weights of the boxes based on the relationships given in the problem statement. One equation will be for the total weight of 1 large and 1 small box; the other will be for the total weight of 70 large and 60 small boxes.

Let L and S represent the weights of Large and Small boxes, respectively. The system of equations is ...

  L + S = 60 . . . . . . combined weight is 60 lbs

  70L +60S = 4000 . . . . weight of boxes in the truck

__

We can solve this by substituting for s in the second equation.

  70L +60(60 -L) = 4000

  10L = 400 . . . . . . . . . subtract 3600, simplify

  L = 40

  S = 60 -L = 20

A large box weighs 40 pounds; a small box weighs 20 pounds.

Breaking Even on Pizza

Suppose the student organization you are apart of has decided to hold a pizza fund-raiser during finals week. Sure we have Cost + Markup = Selling Price, but this sounds more like Pizza + Finals = Success. Your club plans to purchase 50 pizzas and resell them in the student center. For your initial post, I'm hoping you'll get creative: tell us about your student group (and yes, you can make up one that you think you' be apart of).

Next, choose a pizza store to purchase from. You can purchase from somewhere local, or you can choose a chain as well. Research their current promotions on pizzas and find the cost per pizza (you can decide what size of pizzas to purchase since specials will vary). It probably makes sense to explain why you made the choice you did. How much will it cost to purchase 50 pizzas?

Lastly, calculate what you would need to charge per slice to break even. In other words, if you only wanted to sell pizza and not make a profit, what would you charge for each slice?

For your first reply post, reply to your own post. Since this is a fund-raiser, what would you suggest charging for each slice and, based on this, what would the percent markup be? Also, what would the net profit be if you sold all 50 pizzas?

For your second reply post, reply to someone else's post and decide if their cost per slice is too high. Would you pay that much for a slice of pizza? Suppose they only sold 40 pizzas. Will they still make a profit? Will they break even? If you think they should adjust the cost per slice, explain why.

Suppose a potter has 15 choices of glazes to apply on her pottery. She knows that if she applies glaze A OVER glaze B, it may not look the same as applying glaze B OVER glaze A. She wants to test the effect of combining these glazes by dipping a small vessel into 3 of these glazes. She will dip deeply into the first glaze (to see how it looks alone), then less deep into the next glaze (to see how it looks when applied OVER the first glaze) and then barely dip into the third glaze (to see how it looks when applied OVER the previous two glazes).

Required:
How many possible test vessels can be glazed?

Answers

The potter probably doesn't want to apply the same glaze multiple times, in which case she has 15 choices for the first layer, 14 for the second, and 13 for the third, giving

15 * 14 * 13 = 2730

possible test vessels.

On the other hand, it's possible that the potter is fine with re-using the first glaze in the third layer. In that case, whichever glaze is used first is not counted among the options for the second layer, but it comes back for the third layer, so that there would be

15 * 14 * 14 = 2940

test vessels.
