Miguel is ordering 6 bags of cat food from Canada. Each bag has a mass of 7.5 kg. To determine the shipping costs, Miguel needs to know the total weight in pounds. What is the weight of the cat food in pounds? Use 1 kg = 2.2 lbs and do not round any computations.

Answers

Answer:

99 pounds

Step-by-step explanation:

7.5×6=45kg

1kg=2.2lb and we have 45kg because this is direct proportion what you do to one side you havbe to do to the other

so 2.2lb×45 gives you 99 pounds

Work out the size of angle x.
Not drawn accurately
132°
X Х
54°

Answers

Answer:

x = 84

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the given angles and equate to 360

x + 132 + 54 + 90 = 360

x + 276 = 360 ( subtract 276 from both sides )

x = 84

Answer:

x = 84°

Step-by-step explanation:

→ Recall the fact that angles around a point add up to 360°

360 - (90 + 54 + 132 ) = x

→ Simplify

360 - 276 = x

→ Simplify again

84 = x ∴ x = 84°

Find the area of each regular polygon. Round to the nearest tenth.

A= _ In2 ?

Answers

Answer:

Area of the square = 225.0 in²

Step-by-step explanation:

Given polygon is a regular polygon that means given quadrilateral has all sides equal in measure.

And a quadrilateral with all sides equal is known to be a square.

Therefore, area of a square = (Side)²

                                              = (15)²

                                              = 225

                                              ≈ 225.0 in²

A cyclist travels at an average speed of 13 mph for 3 hours.
How far did she travel in miles?

Answers

Answer:

39 miles

Step-by-step explanation:

We know that a cyclist travelled at an average rate of 13 miles per hour for 3 hours and are asked to how far she travelled in miles.

To solve, we need to take into mind that for three hours, the cyclist drove 13 miles per hour.

Meaning that for every hour, 13 miles were driven.

Therefore we need to multiply 13 by 3 to get our answer :

13 miles * 3hrs

39 miles

After 14 years, I shall be three times as old as I was 4 years ago. What is my present age?

Answers

Answer:

Present age = 13 years

Step-by-step explanation:

Let the present age be x years.

14 years after age = (x + 14) years

4 years ago age = (x - 4)

According to the given information:

14 years after age = 3 times 4 years ago age

x + 14 = 3(x - 4)

x + 14 = 3x - 12

14 + 12 = 3x - x

26 = 2x

x = 26/2

x = 13 years

Thus, the present age is 13 years

A pet store owner, Byron, needs to determine how much food he needs to feed the animals. Byron knows that he needs to order the same amount of bird food as hamster food. He needs four times as much dog food as bird food and needs half the amount of cat food as dog food. If Byron orders 600 packages of animal food, how much dog food does he buy? Let b represent the number of packages of bird food Byron purchased for the pet store.

Answers

Answer:

300 bags of dog food

Step-by-step explanation:

4b + 2b + b + b = 600

(dog) + (cat) + (bird) + (hamster) = 600

8b = 600

b = 75

Byron purchased 75 bags of bird food. He needs 4 times that of dog food. So, he purchased 300 bags of dog food.

Step-by-step explanation:

hey hey. i’ll help you. sorry if this is long. :)

okay so let’s think about this. there’s a lot of extra information that we don’t need so let’s get rid of everything up to ”7 years”.

now.. she works 40 hours per week right? and she makes $2.13 per hour. so now that we have that, let’s think what 40 x $2.13 is. if you do the math right you should get 85.2 or $85.20. so that’s in one week, but then in a typical week sheserves 75 tables that have an average bill of $4q. so now that we have those numbers, we take 41 x 75 then add it to our weekly number. so we multiply the two together and we get 3075. not 30.75 but $3075.00! so take that and add it to 85.20.. you should get 3160.2, or $3160.20. but then typically an 18% tip, so let’s go back to the number before (41) and find what 18% of 41 is.

18% of 41 is 7.38 or in this case, $7.38. so once we have that, you’re gonna want to multiply 7.38 by 75 to get that total. if you do that you should get 553.5

okay.. now we have all the numbers we need. we’re already basically done, we just need to add the tips to the other total!

$3160.20 + $553.50 = $3713.70

so in a week, she makes $3713.70

What is a transvarsal line?

A line is called a transvarsal line when it intersects two or more than two lines at two or more than two different points.When a transvalsal intersect two lines at two different points two pairs of alternate angle forms and if they are congruent to each other then the lines which are intersected by a transvarsal are parallel to each other.

We know two are supplimentary if their sum is 180° and we also know that when two lines intersect each other their adjacent angles supplimentary to each other.

∴ Angles that are supplimentary to ∠1 are, ∠4 and ∠2 meaning ∠1 and ∠4 together form a supplimentary angle and ∠1 and ∠2 together form a supplimentary angle.

.

Answers

Answer:

B

Step-by-step explanation:

if you put the rest of your money in a savings account you can use that money for your college fund or maybe buy a car ect.

Answer:

OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for "thinking about your future"

Step-by-step explanation:

In the absence of any more information, I am going to assume that Simple Interest applies. (see attached)

hence the applicable formula is:

A = P(1+rt), where

A = final amount after t years

P = Principal (beginning) amount ($1500 for option A and $1000 for option B)

r = annual interest rate (5% = 0.05 for option A and 5.5% = 0.055 for option B)

t = time (we are asked to evaluate t = 10 years and t = 20 years)

For option A :

P = $1500 and r = 5% = 0.05

A = P(1+rt)

A = 1500 [ 1 + (0.05)t]

at 10 years: A = 1500 [ 1 + (0.05)(10)] = $2,250

at 20 years: A = 1500 [ 1 + (0.05)(20)] =$3,000

For option B :

P = $1000 and r = 5.5% = 0.055

A = P(1+rt)

A = 1000 [ 1 + (0.055)t]

at 10 years: A = 1000 [ 1 + (0.055)(10)] = $1,550

at 20 years: A = 1000 [ 1 + (0.055)(20)] = $2,100

Comparing all the 4 results above, we can see that OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for long term returns.
