What kind of number is 92 and why? if you know the others that'd be great!!
Answer:
hello!
Step-by-step explanation:
The number 92 is a rational number if 92 can be expressed as a ratio, as in RATIOnal. A quotient is the result you get when you divide one number by another number. For 92 to be a rational number, the quotient of two integers must equal 92.
5(-42/-7) + (-15) - (-3)

For a certain city, the temperature each day this week can be described by the inequality below.
3d +6<A
In the inequality, d is the daily temperature in degrees Fahrenheit and A is the average temperature for the year. If A = 54 °F, which statement BEST interprets the solution to the in
A The temperature each day this week was less than 90 "F
B The average temperature for the year was less than 90 °F
c The temperature each day this week was less than 72 °F
DO The average temperature for the year was less than 72 °F
Answer:
Option C.
Step-by-step explanation:
We have the following inequality :
[tex]3d+6<A[/tex] (I)
In which :
[tex]d[/tex] : '' The daily temperature in degrees Fahrenheit ''
[tex]A[/tex] : '' The average temperature for the year ''
We first need to find the solution (the inequality related to the value of [tex]d[/tex]) given that we set [tex]A=54[/tex] °F ⇒
Using the equation (I) :
[tex]3d+6<54\\3d<48\\d<16[/tex]
We find that the ''[tex]d[/tex]'' variable (daily temperature in degrees Fahrenheit) is less than [tex]16[/tex] °F.
The option B and the option D give us an interpretation about the [tex]''A''[/tex] variable.
Only the options A and C give us an interpretion about the [tex]''d''[/tex] variable
Between A and C, the option C is a more accurate option (because 72°F is closer to 16°F).
We answer that the option C best interprets the solution.
Max has the 14 stickers shown
at the right. He wants to put an
equal number of stickers on each
of 2 posters. Draw circles in each
box to represent the stickers Max
puts on each poster.
Answer:
7 Stickers on Each Poster
Step-by-step explanation:
Max has 14 stickers, and 2 posters. You have to divide 14 by 2. Or, put one sticker in each box until you run out of stickers. Eventually, you'll end up with 7 stickers in each poster.
A total of 587 tickets were sold for the school play. They were either adult tickets or student tickets. There were 63 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
'325 adult tickets' is the ACTUAL answer
Step-by-step explanation:
I am editing this because I made a mistake beforehand
Let's say that x=adult tickets. If we subtract 63 tickets from adult tickets you get the number of children's tickets, so that means x+(x-63)=587. Or,
2x-63=587
Add 63 to both sides to get 2x=650. Divide it all by 2, and you get 325 adult tickets

= (2a)^3 - b^3
= (2a -b) (4a^2 + 2ab + b^2)
An expression is defined as a set of numbers, variables, and mathematical operations. The given expression 8a³-b³ can be rewritten in factor form as (2a-b)(4a²+2ab+b²).
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The given expression can be rewritten as,
8a³ - b³
= (2a)³ - b³
It is known that x³-y³ can also be written as (x-y)(x²+xy+y²). Therefore, the above expression can be written as,
= (2a)³ - b³
= (2a - b)[(2a)² + (2a × b) + b²]
= (2a - b)(4a² + 2ab + b²)
Hence, the given expression 8a³-b³ can be rewritten in factor form as (2a-b)(4a²+2ab+b²).

How many chirps can you expect a cricket to make in 1 min when the outside temperature is 50 ° F ? ( it’s not 75)
F = n/4 + 37, for F = 50
50 = n/4 + 37
Subtract 37 from both sides
13 = n/4
Multiply both sides by 4
52 = n

Both of the equations below have the same solution when solved for x. What is the value of t?
Answer:
-.75x-6
Step-by-step explanation:
Step 1: simplify the first equation
1/4(x-28)=2x, or .25x-7=2x.
Step 2: simplify the second equation so that one side equals 2x
13-5x=-7.5x-t. Add 7x to either side to get 13+2x=-.5x-t. Then, subtract 13 from either side and then you have 2x=-.5x-t-13
Step 3: make both equations into one equation
Since 2x=.25x-7, and 2x=-.5x-t-13, then it's safe to say .25x-7=-.5x-t-13.
Step 4: Simplify this final equation
Add .5x to both sides to get .75x-7=-t-13. Then add 13 to both sides to get .75x+6=-t. Then multiply everything by -1 to get -.75x-6=t

A basketball player has a 60% accuracy rate for making free throws. During practice, this player fails to make a free throw three times in a row, but is finally successful on the fourth attempt. P (X equals k )equals (1 minus p )to the power of k minus 1 end exponent p Using the geometric distribution formula, what is the probability of this player successfully making a free throw on the fourth attempt
This question is incomplete, the complete question is;
A basketball player has a 60% accuracy rate for making free throws. During practice, this player fails to make a free throw three times in a row, but is finally successful on the fourth attempt.
p(x=k) = p^k (1-p)^k-1
Using the geometric distribution formula, what is the probability of this player successfully making a free throw on the fourth attempt? Each attempt is independent of each other and answer choices are rounded to the hundredths place.
a.) 0.04
b.) 0.60
c.) 0.40
d.) 0.10
Answer: a.) 0.04
Step-by-step explanation:
Given that;
The basketball player has 60% accuracy of free throws
Now the probability of the player successfully making a free throw on the fourth attempt.
probability of success p = 0.60
number of failure k = 3
the given p.d.f of geometric distribution p(x=k) = p^k (1-p)^k-1
{ 0 <p<= 1 , k=0,1,2,3... }
we substitute our given data
p(x=3) = 0.60^3 (1-0.6)^3-1
= (0.60)^3 (0.40)^2
= 0.216 * 0.16
= 0.035 = 0.04 ( OPTION A)

Car A is moving twice as fast as car B. Car B starts 174. Meters in front of car A. If car A passes car B in 27 seconds, how fast is car B going.
Answer: The speed of car B is 6.44 m/s
Step-by-step explanation:
Let's define:
Sa = Speed of car A.
Sb = Speed of car B.
I assume that at t = 0s, the position of car A is 0m (then at t = 0s, the position of car B is 174m)
Then we can write the positions of each car as:
Pa(t) = Sa*t
Pb(t) = Sb*t + 174m.
We also know that Sa = 2*Sb.
And we know that at t= 27s, car A passes car B.
Then at t = 27s, the positions of both cars must be the same:
Pa(27s) = Pb(27s)
Sa*27s = Sb*27s + 174m.
Now we can replace Sa by 2*Sb (from the above equation)
2*Sb*27s = Sb*27s + 174m
Now we can solve this for Sb.
2*Sb*27s - Sb*27s = 174m
Sb*27s = 174m
Sb = 174m/27s = 6.44m/s.
The speed of car B is 6.44 m/s

Step-by-step explanation:
You can break down 36 through ways down to its prime factors through multiple ways like a facor tree
36

2 2 3 3
Since two and three cannot be broken down anymore, they are prime factors. Also, because you are left with two 2s and two 3s, you would mark that as squared when giving an answer.
