Answer:

121.66

Step-by-step explanation:

To solve, use the Pythagorean Theorem, which says c² = a² + b². Enter 95 as a and 76 as b and square them both. This will give you 9025 for a, and 5776 as b. Add them to get 14,801. So, c² = 14,801. Find the square root of this to get approximately 121.66. So, the third side is about 121.66 in length.

Answer:

Is there an option C?

Answer:

See below.

Step-by-step explanation:

(a) Difference = 71 - 37 = 34 beats/minute.

(b) Number of standard deviations = 34 /18.2 = 1.868.

(c) z score = (x - m )/ s     where m = mean and s = standard deviation

= (37 - 71) / 18.2 = -1.868.

(d)  This  z score lies between -2 and 2 so  a pulse rate of 37 is not significant.

Answer:

An arithmetic sequence has a constant difference between each term. ... A geometric sequence has a constant ratio (multiplier) between each term. An example is: 2,4,8,16,32,… So to find the next term in the sequence we would multiply the previous term by 2.

Answer:

13

Step-by-step explanation:

Add all of the numbers, and divide by the amount of numbers. In this instance, all four added together numbers is 52, and divided by 4 is 13. Hope this helps!

Answer:

The answer is 13.

Step-by-step explanation: In order to find the average in a set of numbers, you must add all numbers and divide them by the numbers of numbers which you have added.

For example for your problem, I added 12 + 4 +16 +20 and I got 52. Then count the numbers which u have added. There are 4 numbers I have added. Then divide that number by the total. So it would be 52/4 and once you divide, you have your answer!

The additional information required to prove the SSS Triangle Congruence Postulate is BC = KC

The congruence postulate is given as:

SSS Triangle Congruence Postulate

The above means that the three sides of the triangles are congruent.

From the figure, the following side lengths are said to be congruent

AK and AB

AC and AC

For the congruence postulate of the triangle to be SSS Triangle Congruence Postulate, then the third corresponding sides must be congruent

Answer:

352 OZ

Step-by-step explanation:

One pound = 16 OZ

take 22 and multiply it by 16

22 x 16 = 352

Answer:

15 ounces per hour

Step-by-step explanation:

This is dimensional analysis, so we need to find conversion factors for ounces per pound and hours per day.  Once we have those we write the equation such that the units we need are left and the others cancel:

22lb/1 day  x  16 ounces/1 lb x 1 day/24hrs = 14.66666666666 ounces per hour

Since the problem was written with no decimals, our answer probably shouldn't either and in most cases like this we want to round to the nearest whole number, which is 15.

empirical rule: about 68% of the data is within 1 standard deviation of the mean.

Step-by-step explanation:

The volume v of the described solid s = 8 cubic units .

Given : a parabola y = 4 - ( x ^ 2 )

Writing eq . y = 4 - ( x ^ 2 ) in terms of x ,

( x ^ 2 ) = 4 - y

x = ± [tex]\sqrt{4 - y}[/tex]

A ( y ) = ± [tex]\sqrt{4 - y}[/tex] * ( ± [tex]\sqrt{4 - y}[/tex] )

A ( y ) = 4 - y

Volume the given solid = [tex]\int\limits^4_0 {( 4 - y )} \, dy[/tex]

                                        = 4 ( 4 ) - [ ( 4 ^ 2 ) / 2 ]

                           = 16 - 8

                           = 8

Hence , the volume v of the described solid s = 8 cubic units .

Answer:

a) System of equations will be:  [tex]x+y=500\: and\:5x+2y=1789[/tex]

b) Number of adult tickets sold =  263

Number of students tickets sold =  237

Step-by-step explanation:

Let:

Number of adult tickets sold = x

Number of students tickets sold = y

a)

As Marc sold total 500 tickets, the expression will be: [tex]x+y=500[/tex]

Student tickets cost $2 and adult tickets cost $5. Marc's sales totalled $1,789.

The expression will be: [tex]5x+2y=1789[/tex]

So, system of equations will be:  [tex]x+y=500\: and\:5x+2y=1789[/tex]

b)

Solve the system to find value of x and y

Let:

[tex]x+y=500--eq(1)\\5x+2y=1789--eq(2)[/tex]

Multiply equation 1 by 2 and subtract

[tex]2x+2y=1000\\5x+2y=1789\\-\:\:\:-\:\:\:\:\:\:\:\:\:-\\------\\-3x=-789\\x=\frac{-789}{-3}\\x=263[/tex]

We get value of x = 263

Now finding value of y by putting value of x in eq(1)

[tex]x+y=500\\263+y=500\\y=500-263\\y=237[/tex]

We get value of y = 237

Number of adult tickets sold = x = 263

Number of students tickets sold = y = 237

Answer:6
-3y= 6 - 2x

Answer:

y=-2x-2

Step-by-step explanation:

Parallel means the same slope from the given slope in the statement.

To find the slope-intercept form equation, you must use the point-slope form which is y-y1=m(x-x1).

The given point (0, -1) includes 0 as the x-intercept and -1 as the y-intercept.

Because parallel is the same slope, the slope we'll insert into our equation is -2.

The point-slope form substituted with the given point and slope looks like the following:

y-(-1)=-2(x-0) which can be simplified to y+2=-2x+0

Solve the simplified equation.

y+2=-2x+0

 -2        -2

y=-2x-2

That's the final equation.

Answer:

congruent

Step-by-step explanation:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

so yes, they are congruent because they have the same angle

Answer:

108 degrees

Step-by-step explanation:

Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:

Combine like terms: 14x - 16 = 180

Add 16 to both sides: 14x = 196

Divide both sides by 14: x = 14

Now that you know x, you can plug it into the expression for angle A (7x+10):

A = 7(14) + 10 = 98+10 = 108
