The difference between the maximum number of computers and the minimum number of computers is 35. ​ ​Which statement are true about the number of computers in these libraries? ​Select each correct answer. A There must be 3 libraries with 12 computers. B A library could have less than 12 computers. C A library could have more than 50 computers. D All libraries must have less than 35 computers. E At least 1 library does bot have 12 computers.

Answer:

If I wanted to safely climb a 50 foot wall, I would use a 51 foot ladder.

Step-by-step explanation:

If I wanted to climb a fifty foot (50 ft) wall, I would use a fifty one foot (51 ft) ladder because the safe way to position a ladder against the wall requires that I leave one foot (1 ft) distance from the base of the ladder to the wall. That way, the ladder won't be too close nor too far from the wall.

Answer:

2.30 = ?

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp side/ hypotenuse

sin 50 = ? / 3

Multiply each side by 3

3 sin 50 = ?

2.298133329 = ?

To the nearest hundredth

2.30 = ?

Answer:

Givens

[tex]DR=PT=3cm[/tex] and [tex]RP=4cm[/tex]

Points D, R, P and T are collinear.

The image attached shows a representation of this problem.

By sum of segments, we have

[tex]DT=DR+RP+PT[/tex]

Replacing all given values, we have

[tex]DT=3+4+3=10 \ cm[/tex]

Therefore, the segment DT is 10 centimeters long.

Now, we know that point E is the center of segment RP, which means is a middle point, divides the segment equally. So, to prove that segment DT is symmetrical regarding point E, we need to prove that both sides are equal.

[tex]RE=EP=2cm[/tex], by definition of middle point.

By sum of segments, we have

[tex]DR+RE=3+2=5cm\\EP+PT=5cm[/tex]

Which means [tex]DR+RE=\frac{DT}{2}\\ EP+PT=\frac{DT}{2}[/tex].

Therefore, segment DT is symmetrical regarding point E.

you could use a calculator, but it works like this too i guess. :P also you could just try and guess, "what squared (multiplied by itself) is 25" good luck

Answer:

5 should be the answer for the square root

By Probability, 0.25 is simulation could you use to answer questions about whether a surfer will see a dolphin.

What does a probability simple definition entail?

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%. Probability is a measure of how likely or likely-possible something is to happen.

                                         For instance, the chance of flipping a coin and obtaining heads is 1 in 2, as there is only one method to acquire a head and there are a total of 2 potential outcomes (a head or tail). P(heads) = 12 is the formula.

the beach lifeguards, there is a 25% chance.

                25%  = 1/4 = 0.25

Answer:

∠B = 36.87

Step-by-step explanation:

Since you are trying to find the angle measurement, you must use the inverse of cosine: [tex]cos^{-1}[/tex] (you're using cosine because you have the opposite side and adjacent side):

[tex]cos^-1(4/5)[/tex]

Answer:

(x-9)(x-3)

Step-by-step explanation:

Look to the number on the right, 27, and list out the factors. (1 and 27, 3 and 9, -1 and -27, -3 and -9)

Next, find the factors that would equal the middle number, -12, when added. -3 and -9 add to -12. Therefore, choose these numbers and put them in the form (x-9)(x-3).

Answer:

In 6 years form now, the balance in Gordon's account will be = {$1,200 x [1 + (2.5% x 6 years)]} = $1,380

his account will have earned = 2.5% x 6 years x $1,200 = $180 in interests over the six years

In 6 years form now, the balance in Bailey's account will be = $900 x (1 + 3.25%)⁶ = $1,090.39

his account will have earned = $190.39 in interests over the six years

Bailey's account earned more interest than Gordon's, even though his initial balance was much lower. This was due to higher interest rates and more important, because Bailey earned compound interest.

Answer:

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AC² = AB² + BC² , substitute values

AC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )

AC = [tex]\sqrt{225}[/tex] = 15 cm

-------------------------------------------

The area of Δ ABC is calculated as

A = [tex]\frac{1}{2}[/tex] × BC × AB = [tex]\frac{1}{2}[/tex] × 12 × 9 = 6 × 9 = 54 cm²

Answer:

Step-by-step explanation:

5sin(3pix)+8=4

5sin(3pix) = -4

sin(3pi x) = -0.8

Basic angle: sin^-1(0.8) = 0.927295218

3pi x = pi+0.927295218, 2pi-0.927295218

Part A. Yes, these ratios forms a proportion

Part B-  the ratio of the number of friends in Case 1 to the number of friends in Case 2 is 5:1

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The ratios in cases 1 and 2 form a proportion. IT can be seen by dividing case a by 5 which gives 4:3;

i.e 20:15

If we divide both numerator and denominator by 5, then we have 4/3.

This shows case 1 and 2 have the same proportions of friends to strangers.

Part B; The number of friends in case 1 is 20 while in case 2 is 4.

we have, 20:4

= 20  4

Dividing each by 4, we have 5:1.

Which means that the ratio of friends that in case 1 to case 2 is 5:1.

Answer:

6 ways

Step-by-step explanation:

The total number of people we have entering Kennywood is 6, since it’s Jim with 5 of his friends.

Now, we can only have movement through the game one at a time

The number of ways they can move through the gate one at a time is 6C1 ways

and that is mathematically;

if we are to select a number of r items from a total of n, the number of combinations or ways is;

nCr = n!/(n-r)!r!

Applying these to the problem at hand, we have

6!/(6-1)!1! = 6!/(5!)(1!) = (6 * 5!)/5! = 6 ways

A)

X/3 -2 = 6

Add 2 to both sides:

X/3 = 8

Multiply both sides by 3:

X = 24

B)

X/5 +1 = 5

Subtract 1 from both sides:

X/5 = 4

Multiply both sides by 5:

X = 20

Answer:

a) 24.

b) 20.

Step-by-step explanation:

a) x/3 - 2 = 6

x/3 = 6 + 2 = 8

x = 3*8

x = 24.

b).  x/5 + 1 = 5

x/5 = 5 - 1 = 4

x = 5*4

x = 20.

Answer:

x=((log(81))/(log(3))+2)/3

Step-by-step explanation:

so what you want to do is get 3x-2 out of the exponent

you can do that by using log

so apply log to both sides and you get

log(81)=(3x-2)log(3)

the 3x-2 is moved in front of the log due to a log rule

then (log(81))/(log(3))=3x-2

(log(81))/(log(3))+2=3x

((log(81))/(log(3))+2)/3=x

then use a calculator to find the exact value
