Answer:
hey!
you said:
A bird was flying and saw a bunch of others and said to them, hello one hundred, and one of the birds from the bunch said we need twice the number of us and one of you (The bird flying) to be one hundred, and now my question is how many birds were flying, (not in total) but before the bird who was flying saw them.
Step-by-step explanation:
i think that the answer is 49.5 bids were flying because there needs to be tice the number plus 1 to get to 100. iknow there cant be 49.5 birds so round it up to 50 and plus the bird i see that there may have been 50 birds flying.

The total length of 2 pieces of rope is
108cm. If one piece is 18cm shorter, what is
the length of the longer piece?
Answer:
63 cm
Step-by-step explanation:
piece 1: x
piece 2: x - 18
First you would subtract 2x - 18 = 108
Second you would add 108 + 18 = 2x
Third you would divide 126 divided by 2x = 63
So that would mean x = 63
Answer:
63cm
Step-by-step explanation:
2 pieces of rope, and one is shorter by 18cm.
piece 1: x
piece 2: x-18
Add the equations together, combine both pieces
2x-18
2x-18 = 108
108+18 = 2x
126 = 2x
x = 63
Which of the binomials below is a factor of this trinomial?
X2-16x + 28
O A. x+7
O B. x2 + 7
O c. x+4
O D. X-14
Answer:
x-14
Step-by-step explanation:
The binomial which is a factor of this trinomial is (x- 14).
What is Trinomial?An algebraic expression with three terms is called a trinomial.
Examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z.
Given:
p(x) = x²-16x + 28
If x+ a is factor of any polynomial p(x) then x= -a satisfy the polynomial.
factorizing p(x)
x²-16x + 28
= x²-14x + 2x + 28
= x( x- 14) + 2 (x+ 14)
= (x- 14)(x+ 2)
Hence, the binomial is (x- 14).

Mr Frank purchased 5_1/4 pounds of rocks. He used 3/5 of a pound on one aquarium. He then split the rest of the rocks between his three remaining aquariums. How many rocks will be in one aquarium?
Answer:
1_11/20 pounds, or 1.55 pounds.
Step-by-step explanation:
Since at the beginning, he had 5 1/4 pounds and used 3/5, we subtract the amount of pounds. We are then left with 93/20 pounds, which he then splits among 3 containers. Dividing by three, we then get 31/20 pounds in one aquarium, or 1 11/20 pounds in each aquarium or 1.55 pounds.
The owners of a motel in Florida have noticed that in the long run, about 40% of the people who stop and inquire about a room for the night actually rent a room. (a) How many inquires must the owner answer to be 99% sure of renting at least one room? inquiries (b) If 20 separate inquiries are made about rooms, what is the expected number of inquiries that will result in room rentals? inquiries
Answer:
(a) n = 9 inquiries
The owner must answer 9 inquiries to be 99% sure of renting at least one room.
(b) E(x) = 8 inquiries
Therefore, the expected number of inquiries that will result in room rentals is 8.
Step-by-step explanation:
The given problem can be solved by Binomial distribution.
Let x be the people who stop and inquire about a room for the night actually rent a room.
P(x) = ⁿCₓ pˣ (1 - p)ⁿ⁻ˣ
Where n is the number of trials, x is the variable of interest and p is the probability of success.
(a) How many inquires must the owner answer to be 99% sure of renting at least one room?
For the given case, we have p = 0.40 and we want to find n such that
P(x ≥ 1) = 0.99
we know that
P(x ≥ 1) = 1 - P(x < 1)
P(x ≥ 1) = 1 - P(x = 0)
So,
1 - P(x = 0) = 0.99
P(x = 0) = 1 - 0.99
P(x = 0) = 0.01
For x = 0 and p = 0.40
P(x = 0) =(ⁿC₀) (0.40)⁰ (1 - 0.40)ⁿ⁻⁰
0.01 = (1)(1)(0.60)ⁿ
0.01 = 0.60ⁿ
ln(0.01) = ln(0.60ⁿ)
ln(0.01) = n ln(0.60)
n = ln(0.01)/ln(0.60)
n = 9.01
Rounding off to nearest whole number
n = 9 inquiries
Therefore, the owner must answer 9 inquiries to be 99% sure of renting at least one room.
(b) If 20 separate inquiries are made about rooms, what is the expected number of inquiries that will result in room rentals?
The expected number of inquiries is given by
E(x) = n×p
For the given case, we have n = 20 and p = 0.40
E(x) = 20×0.40
E(x) = 8 inquiries
Therefore, the expected number of inquiries that will result in room rentals is 8.
Jillian walked 0.5 miles before she started jogging at an average pace of 5 miles per hour. The equation d = 0.5 + 5t
can be used to relate the total distance, d, in miles to the time, t, that Jillian spent jogging. What are the independent
and dependent variables?
Answer:
independent: tdependent: dStep-by-step explanation:
In an equation of the form ...
variable = expression
we generally consider the variable on the left to be the dependent variable. The variable in the expression is the independent variable.
Here, the equation ...
d = 0.5 + 5t
suggests that the dependent variable is d; the independent variable is t.
Answer:
The independent variable is time and the dependent variable is distance.

Step-by-step explanation:
-5(x - 1) = 2x - 7x + 5
Answer:
This is true! 1x=1
Step-by-step explanation:
So let's rewrite the question again.
-5(x - 1) = 2x - 7x + 5
So we will solve from left to right.
-5(x-1) <- In here, we cannot add a variable to a whole number. So, we simply multiply -5 by x and -1.
-5(x - 1) = -5x+5
2x - 7x + 5 <- Here, we can subtract 2x-7x. They are both variables. But, we cannot add 5 to a variable.
2x - 7x + 5 = -5x+5
Now, here is the equation that we have so far.
-5x+5 = -5x+5
+5x +5x
----------------------
5=5
-5 -5
0=0
So in here, we can have anything. 1, 2, 3, 4, 5, 6, 100, anything. So, the answer is:

ASAP HELP Which equation is equivalent to: 3r=90−5 ?
A. 3r+5=90
B. −3r=−90−5
C. −3r=90+5
D. 3r=90+5
Answer:
The answer is A.
This is because adding 5 to both sides of the original equation gives us A.
An equivalent equation to 3r = 90 - 5 is 3r + 5 = 90
The correct answer is an option (A)
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
What is equivalent equations?"The equations that have the same answer or solution."
For given question,
We have been given an equation 3r = 90 - 5
We know that the addition property of equality which states that when the same quantity is added to both sides of an equation, the equation does not change.
⇒ 3r = 90 - 5
Add 5 on the both the sides of the equations.
⇒ 3r + 5 = 90 - 5 + 5
⇒ 3r + 5 = 90 + 0
⇒ 3r + 5 = 90
Therefore, an equivalent equation to 3r = 90 - 5 is 3r + 5 = 90
The correct answer is an option (A)

Distance to bus stop = 320 ÷ 100 = 0.32 km
Total distance= 0.32 km + 2.85 km

What are the values of x and y in the matrix equation below?
Answer : value of x and y in the matrix equation is:
x = -3
y = +4, -4
Step-by-step explanation :
The matrix expression is:
[tex]\left[\begin{array}{ccc}x+4\\y^2+1\end{array}\right]+\left[\begin{array}{ccc}-9x\\-17\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]
First we have to add left hand side matrix.
[tex]\left[\begin{array}{ccc}(x+4)+(-9x)\\(y^2+1)+(-17)\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]
Now we have to add left hand side terms.
[tex]\left[\begin{array}{ccc}x+4-9x\\y^2+1-17\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}4-8x\\y^2-16\end{array}\right]=\left[\begin{array}{ccc}28\\0\end{array}\right][/tex]
Now we have to equating left hand side matrix to right hand matrix, we get:
[tex]\Rightarrow 4-8x=28\text{ and }y^2-16=0\\\\\Rightarrow 8x=4-28\text{ and }y^2=16\\\\\Rightarrow x=-3\text{ and }y=\pm 4[/tex]
Therefore, the value of x and y in the matrix equation is -3 and +4, -4 respectively.
Answer:
D is wrong. The correct answer choice is C ( x=-3 and y= +4, -4)
