========================================================

Explanation:

Her original balance starts off at $32. After making the $60 purchase, her balance becomes 32-60 = -28 dollars. We wouldn't say 60-32 = 28 because the expense is larger than her balance.

Being in the negative territory means Emily is in debt to the bank, until she can get her balance back to $0 or higher. Since they charge her $3 a day for being in the negative area, and her balance is like this for 7 days, then they charge a total of 7*3 = 21 dollars.

So the -28 will drop to -28-21 = -49 dollars

If she doesn't want any more charges done, she needs to deposit $49 or more into the account on the 8th day.

Answer:

x = 6

y = 13

Step-by-step explanation:

x + y = 19

x - y = -7

To eliminate x, subtract ther second equation from the first

2y = 26

y = 13

To eliminate y, add the equations

2x = 12

x = 6

Answer:

x = 46, y = 67

Step-by-step explanation:

x = ∠ AEC = 46 ( alternate angles )

Since Δ ACE is isosceles then the base angles are congruent, then

y = [tex]\frac{180-46}{2}[/tex] = [tex]\frac{134}{2}[/tex] = 67

Answer:

x=46° and y=67°

Step-by-step explanation:

triangle ACE is isosceles, meaning <A=<B=y

any triangle is add up to 180. <A+<B+<C=180

y+y+46=180

2y=180-46

2y=134

divide both sides by 2

y=134/2

y=67°

for angle x°

since AB is parallel to CD,hence

<AEC=<ECD

x=46°

Answer:

150.72

Step-by-step explanation:

Area of circle formula is r²π

Do find radius you do d/2, diameter/2. 13/2= 6.5

6.5 * 6.5 = 42.25

π  is also known as 3.14

42.25 * 3.14 = 132.665

That is the area of the smaller one.

For the larger one, 19/2 = 9.5

9.5 * 9.5 = 90.25

90.25 * 3.14= 283.385

Now you subtract both of them and the difference is 150.72.

Hope this helps !!

Answer

150.72 m2

Step-by-step explanation:

Find the radius of the larger

merry-go-round.

19^2 = 9.5

Substitute 9.5 for r in the formula for the

area of a circle.

A-n • 9.52

= 71 -90.25

- 283.385

Find the radius of the smaller

merry-go-round.

13-^-2-6.5

Substitute 6.5 for r in the formula for the

area of a circle.

A~n • 6.52

= n - 42.25

-132.665

Subtract the area of the smaller merry go-round from the area of the larger

merry-go-round.

283.385 - 132.665 = 150.72

Answer:

I am against testing on animals.

Step-by-step explanation:

Personally based on my faith humans are told to make the earth their dominion. To dominate doesn't only mean to use to one's advantage but to also take care of and replenish any loss caused by unintentioned damage. Animals do have feelings, both emotional and physical, and though those feelings may not be quite as developed as those of humans, they are undoubtedly existent. With how far technology has come when it comes to predictability and how calculated and concise science experiments have become, if as the most advanced species on earth we are still unable to determine how long a deodorant or lipstick or eyeliner would last without torturing other species, then what exactly have we achieved, and are we truly any more advanced than we were 10000 years ago? And for things that quite necessarily do need testing like vaccines and medicines it is to some extent understandable, but then again if the death sentence still exists for offenders of heinous crimes , why don't we instead of killing those criminals dedicate them to science and research for testing of vaccines and medicines. That way we all benefit from it. They don't have to die and neither do the animals and neither do we. It's a far stretch of a solution but alternatives can be made. Where there's a will there's a way.

Answer:

1.2r

Step-by-step explanation:

The arc length in terms of r will be equal to 1.2r.

The distance between two places along a segment of a curve is known as the arc length. Curve rectification is the process of measuring the length of an irregular arc section by simulating it with connected line segments.

It is given that the angle in radians is 1.2 and the radius is r then the arc length will be calculated as below:-

The arc length = Angle x radius

The arc length  = 1.2 x r

The arc length  = 1.2r

Therefore, the arc length in terms of r will be equal to 1.2r.

Answer:

$52.08

Step-by-step explanation:

There are 12 months in a year, so 3 years will have 36 months.

Find how much money she has to save in total:

6375 - 4500

= 1875

Divide this by 36 to find how much she has to save each month:

1875/36

= $52.08

So, she will have to save approximately $52.08 each month
