hello good evening

be happy always

Edit, my calc is broken, sorry for the inconvenience, please disregard.

The number decreased by 14%  is found as the 133.7.

A percentage is defined as a relative value that represents the hundredth part of any quantity. Each percent (symbolized 1%) is one hundredth portion; thus, 100 percent symbolizes the entire amount and 200 percent defines twice the given amount.

Let the original number be 'x'.

number decreased by 14%

That means of x = 460.

Then,

86% of x = 1115

86x/100 = 115

x = 11500/86

x = 133.7

The original number be 133.7.

Answer:

C

Step-by-step explanation:

I think it would be easiest to see these numbers in decimal form to determine which number is the greatest and which is the smallest.

2 as a decimal=2.0

Square root of 7 as a decimal= 2.64575131106

1/3 as a decimal= 0.3333333333333333333333333333333333333333333...

So, 0.3333333...<2.0<2.64575131106

or 1/3, 2, square root of 7

Answer is C

Answer:

x^23

Step-by-step explanation:

Cancel the common factor of x^5^2 and x^2

Factor x^2 out of x^5^2

(x^2) (x^5^2-2) / (x^2)

cancel common factors

x^25-2 = x^23

(30*100):45=

3000:45=66.67

Answer:8:36

Step-by-step explanation:

Answer: 1 : 4

Step-by-step explanation:

The simplified ratio of large dogs to small dogs is 1 : 4.

The original, unsimplified ratio would be 2 : 8, because there are 2 large dogs for every 8 small dogs. But to simplify it, we can divide each side by 2.

2 ÷ 2 = 1, while 8 ÷ 2 = 4.

Therefore, the simplified ratio of large dogs to small dogs is 1 : 4.

Hope this helps!

Answer:

100

Step-by-step explanation:

360 is the total degree for every quadrilateral. 80+75+105=260. 360-260=100.

Answer:

1:4

Step-by-step explanation:

Answer:

1:4

Step-by-step explanation:

15 is the common factor so divide both numbers by 15 and that's what you get

Answer:

Option (2)

Step-by-step explanation:

Equations of the lines have bee given as,

y = [tex]\frac{4}{3}x-5[/tex]

y = [tex]\frac{4}{3}x+3[/tex]

Both the equations are in the slope intercept form. (y = mx + b)

They have same slopes but different y-intercepts.

Same slopes of the equations define the lines to be the parallel lines.

Therefore, Option (2) will be the correct option.

Answer:

One ticket equals $169

Step-by-step explanation:

The family buys 4 airline tickets online.

The travel insurance costs $19 per ticket.

The total cost is $752.

A.

An equation that models this problem could be

Basically, we know that the insurance costs $19 which represents an additional costs after the price per ticket, that's why we need to add them. Then, we know that the familiy bought 4 tickes, that's why we multiply by 4, and finally, the total cost must be equal to 752, according to the problem.

B.

To find the price of one ticket, we just need to solve the equation for

Therefore, one ticket costs $169.

The derivatives of sin(x) follow a simple pattern:

f(x) = sin(x)

f '(x) = cos(x)

f ''(x) = - sin(x)

f '''(x) = - cos(x)

f ''''(x) = sin(x)

and so on. 96 is a multiple of 4, so

f ⁽⁹⁶⁾(x) = sin(x)

Answer: g=-424

Step-by-step explanation:

Given

-g+2(3+g)=-419+1

Expand parenthesis

-g+6+2g=-419+1

Combine like terms

g+6=-418

Subtract 6 on both sides

g+6-6=-418-6

g=-424

Hi how are you doing Jasmine

Answer:

Well, BLM has done a lot.

It brought people together, but also shredded others from each other.

Answer:

43

Step-by-step explanation:

You are going to want to substitute the x of the function f(x) with the function of g(x) and replace the x in g(x) with -4

(f+g)(-4) = 4+3((-4)^2-3)

=43
