Answer this for me real quick

Answer:

Step-by-step explanation:

=9.88/132 (this is in fraction form)

for calculating percentage just multiply the fraction by 100%

=9.88/132*100%

=9.88*100/132

=988/132

=7.48 %

Step-by-step explanation:

Factor x^2 + 11x + 28 using the AC method.

Answer:

[tex]30[/tex]; Obtuse, isosceles triangle OR "[tex]B[/tex]"

Step-by-step explanation:

If you replace the [tex]z^o[/tex] variable with [tex]30^o[/tex] on both angles.

The angles will be:

[tex]30^o[/tex]

[tex]120^o[/tex] ([tex]4(30)=120^o[/tex])

[tex]30^o[/tex]

This angle is isosceles (two sides are equal). It is obtuse (there is one angle that is greater than [tex]90^o[/tex]).

Answer:  (x,y) = (-1, 1)

This means that x = -1 and y = 1

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

Explanation:

The first equation says that y is the same as 2x+3

That allows us to substitute y for 2x+3 in the second equation like so:

2x+5y = 3

2x+5( y ) = 3

2x + 5(2x+3) = 3 .... y replaced with 2x+3

2x+10x+15 = 3

12x+15 = 3

12x = 3-15

12x = -12

x = -12/12

x = -1

Then we'll substitute this into the first equation to find y

y = 2x+3

y = 2(-1) + 3 .... x replaced with -1

y = -2+3

y = 1

Together x = -1 and y = 1 pair up to form the ordered pair solution (x,y) = (-1,1)

If you were to graph y = 2x+3 and 2x+5y=3 on the same xy grid, then you should see that the two lines intersect at the location (-1,1). This is a visual way to determine the solution quickly through use of a graphing calculator.

Answer:

x = 55

y = 70

Step-by-step explanation:

since it's all sides are equal its an equilateral triangle

each angle of an equilateral triangle is 60°

therefore,

y - 10 = 60 => y = 60 + 10

y = 70

x + 5 = 60 => x = 60 - 5

x = 55

Answer:

x+5=y-10

x-y = -15

y-10+X+5+X+5=180

2x+y =180

x-y+2x+y =180-15

3x.=165

x. =55

2x+y =180

y =180-(110)

y =70

Answer:

the surface area is 112 ft^2

Step-by-step explanation:

if you separate listen to two different rectangles you get what's a rectangle a being 3 + 10 + 3 equals 16 * 2 what gives you 32 okay and rectangle b being 3 + 2 + 3 what gives you 8 x 10 that gives you the area of 80 now you add the area both rectangles being 32 + 80 and to get a hundred and twelve feet squared

Answer:

[tex]P (Yes | Nebraska) = 0.10[/tex]

Step-by-step explanation:

Given

See attachment for contingency table

Required

[tex]P (Yes | Nebraska)[/tex]

From the contingency table, we have:

[tex]P (Yes\ n\ Nebraska) = 0.044[/tex]

[tex]P (No\ n\ Nebraska) = 0.400[/tex]

The required can be represented as:

[tex]P (Yes | Nebraska) = \frac{P(Yes\ n\ Nebraska)}{P(Nebraska)}[/tex]

Where

[tex]P (Nebraska) = P (No\ n\ Nebraska) +P (Yes\ n\ Nebraska)[/tex]

So, we have:

[tex]P (Nebraska) = 0.400 + 0.044[/tex]

[tex]P (Nebraska) = 0.444[/tex]

So, we have:

[tex]P (Yes | Nebraska) = \frac{P(Yes\ n\ Nebraska)}{P(Nebraska)}[/tex]

[tex]P (Yes | Nebraska) = \frac{0.044}{0.444}[/tex]

[tex]P (Yes | Nebraska) = 0.10[/tex] --- approximated

24 ×12 /3 = 96 units³

Answer:

15d + 74 > 200

d > 8.4 days

Step-by-step explanation:

Total cans needed = over 200

Number of cans they have = 74

Number of cans needed per day = 15

Number of days = d

The inequality is

74 + 15d > 200

Also written as

15d + 74 > 200

15d > 200 - 74

15d > 126

d > 126/15

d > 8.4 days

Answer:

15d + 74 > 200

d > 8.4 days

Step-by-step explanation:

Total cans needed = over 200

Number of cans they have = 74

Number of cans needed per day = 15

Number of days = d

The inequality is

74 + 15d > 200

Also written as

15d + 74 > 200

15d > 200 - 74

15d > 126

d > 126/15

d > 8.4 days

Answer:

4.9

Step-by-step explanation:

use this equation : [tex]a^2 + b^2 = c^2[/tex] (your hypotenuse is always going to be c)

 [tex]7^2 - 5^2 = b^2[/tex]

 [tex]49 - 25 = b^2\\[/tex]          

         [tex]24 = b^2[/tex]

      [tex]\sqrt{24} = b[/tex]

        [tex]4.9 = b[/tex]

Answer:

Not enough info

Step-by-step explanation:

Find the length from the school to the community center (this is the shortest route).

2^2+7^2 = c^2

c = sqrt(53)

The amount of time the trip takes depends on how long it takes Miguel to walk one city block.

sqrt(53)*lengthOfTimeForOneCityBlockInMinutes = the minimum time.

Answer: Hi I think that I can help you with your problem!

Let  which means

Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.

To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.

So, we can rewrite  as:

......(1)

Now, let us multiply the above with 10.

....... (2)

Now, let us subtract (1) from (2):

So, in simplified fractions:

Answer:

942m^3

Step-by-step explanation:

Given data

Radius of cone= 5m

Height= 12 m

We know that volume of a cone is given as

V= πr^2h

V= 3.14*5^2*12

V= 3.14*25*12

V= 942 m^3

Hence the volume is 942m^3
