Is it polynomial? In case of a polynomial, write its degree: t^2-1/2t+root 5
Answer:
Step-by-step explanation:
An algebraic expression with non.zero coefficients and variables having non-negative integers as exponents is called a polynomial.
Yes, It is a polynomial. The highest power of the variable is the degree of the polynomial.
So, Degree = 2

4.2kg of oranges are £8.76. How much does 2kg cost
Answer:
x = 4.17
Step-by-step explanation:
We can use a ratio to solve
4.2 k 2 k
---------------- = ---------------
8.76 x
Using cross products
4.2 * x = 2 * 8.76
4.2x =17.52
Divide by 4.2
x=4.17
Answer:
2kg cost £4.18
Step-by-step explanation:
4.2 kg of oranges cost £8.76
:. 1 kg of orange cost £8.76/4.2 = £2.09
2kg cost 2 × £2.09 = £4.18

2x+1
Step-by-step explanation:
f(g(x)) = 2(x-3)+7
=2x-6+7
=2x+1
Answer:
2x+1
Step-by-step explanation:
We know that g(x)= x-3
So f(g(x))= f(x-3)
We put it in the equation :
f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1

1 1/8, 0.7, and 1.4
Answer:
1.4, 1 1/8, 0.7
Step-by-step explanation:
1 1/8 is equal to 1.125 which it makes it less than 1.4 but more than 0.7.
Answer:
[tex]0.7, \frac{11}{8},1.4[/tex]
Step-by-step explanation:
In order to understand what numbers are greater and what numbers are smaller, we need to make them have the same common denominator. So firstly, we turn all of these numbers into fractions, and we get...
[tex]0.7 = \frac{7}{10}\\\\1.4 = \frac{14}{10}\\\\\frac{11}{8 }= \frac{11}{8 }[/tex]
Now we, need to find the least possible number divisible by 10 and 8, to find the least common denominator. And we get, that the least common denominator is 40, and knowing this, now we have to take each fraction and turn it into an equivalent fraction with the denominator of 40. So we do...
[tex]\frac{11}{8}= \frac{(11)(5)}{(8)(5)}= \frac{55}{40}\\\\\frac{7}{10} = \frac{(7)(4)}{(10)(4)} = \frac{28}{40} \\\\\frac{14}{10} = \frac{(14)(4)}{(10)(4)} = \frac{56}{40}[/tex]
Now we can put these fractions in order from least to greatest...
[tex]\frac{28}{40} < \frac{55}{40}<\frac{56}{40}[/tex]
Therefore, we know that...
[tex]0.7 < \frac{11}{8} < 1.4[/tex]

Step-by-step explanation:
the length of rope P is three times the length of rope Q. After 10cm of rope is cut from rope P and rope Q respectively, the length of rope P is four times the length of Q. Calculate the original length, in cm, of rope P before it is cut.
Answer:
150 cm
Step-by-step explanation:
The information in the question includes;
The length of rope P = 3 × The length of rope Q
The length of rope P - 10 cm = 4 × (The length of rope Q - 10 cm)
Let p represent the original length of rope P and let q represent the original length of rope Q, we have;
p = 3·q...(1)
p - 10 = 4·(q - 10)...(2)
Expanding equation (2) gives;
p - 10 = 4·q - 40
∴ p = 4·q - 40 + 10 = 4·q - 50
p = 4·q - 50...(3)
Equating the values of p in equation (1) and equation (3) gives;
p = 3·q, and p = 4·q - 50, therefore, by the substitution property of equality, we have;
3·q = 4·q - 50
50 = 4·q - 3·q = q
q = 50
p = 3·q
∴ p = 3 × 50 = 150
The original length of P before it was cut, p = 150 cm.

Answer:

Step-by-step explanation:
Step 1 find probability of pulling 1 pink marble
Like stated previously probability = # of favorable outcomes / # of possible outcomes
The favorable outcomes is what we want to happen
We want to pull a pink marble and there are a total of 3 pink marbles
So # of favorable outcomes = 3
To find the # of possible outcomes we simply find the number of marbles. There are a total of ten marbles
So probability of pulling one pink marble = 3/10
Step 2 find the probability of pulling another pink marble ( IMPORTANT NOTE: It says to find the probability of pulling 2 pink marbles if the first one is NOT put back before the second pull. this meaning that we must subtract 1 from the total # of marbles and 1 from the total # of pink marbles )
3 - 1 = 2
10 - 1 = 9
So after the first pull there would be 2 pink marbles out of 9 total marbles
So the probability of pulling a pink marble on the second pull is 2/9
Finally we multiply the two probabilities together to find our answer
3/10 * 2/9 = 1/15

Find the value of L in the equation.
s=(n÷2)(a+L)
Answer:
2s/n-a=L
Step-by-step explanation:
So first we divide (n÷2) so it will be s/(n÷2) =a+L. Next we subtract L and get s/(n÷2)-a. That's not it yet, since 2 is being divided in the denominator, we have to reciprocal it meaning multiply, it to the top value. So it would 2s/n-a=L. But you can just leave it like that if you desire and your teacher doesn't mind.
Em 2016 o brasil vendeu para o exterior cerca de 3,5 milhoes de ingressos para espectadores estrangeiros sabendo total de ingressos vendidos é de 7,9 milhoes a quantia de ingressos vendida para a população brasileira foi de? a) 4.050.000 B) 4.400.000 C) 5.000.000 D) 5.500.000
Responder:
4.400.000
Explicação passo a passo:
A quantidade total de ingressos vendidos = 7,9 milhões = 7.900.000
Desse total, o valor vendido ao espectador estrangeiro = 3,5 milhões, = 3,5 milhões
O valor dos ingressos vendidos ao espectador brasileiro será a diferença entre o valor total do ingresso vendido e o total vendido ao espectador estrangeiro.
7.900.000 - 3.500.000 = 4.400.000

Answer: the root of 145 so b
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Use the Pythagorean theorem:
a^2 + b^2 = c^2
9^2 + 8^2 = c^2
81 + 64 = c^2
144 = c^2
[tex]\sqrt{144}[/tex] = c

Answer:
36 degrees
Step-by-step explanation:
Angles on a line equal 180
180-117=63
a=63
Angles in a triangle equal 180
180-(63+81)=36
b=36 degrees
Answer:
a=117(being straight line angle)
a=180-117
a=63ans
a+b+81=180(being the sum of the angle of triangle)
b+63+81=180
b+144=180
b=180-144
b=36ans

120 to 150 find the percentage of increase
Answer:
25%
Step-by-step explanation:
increase by = 150 - 120
=30
increase percent = 30/120 * 100%
=3000/120
=25 %
Answer:
25%
Step-by-step explanation:
Percentage increase=(new value-original value)/(original value) x 100%
Percentage increase=(150-120)/120 x 100%
Percentage increase=30/120 x 100%
Percentage increase=1/4 x 100%
Percentage increase=25%
Let A and B be two independent events. If p(A)=3/5 and p(B')=1/3 then the value of p(AUB)' is equal to?
Answer:
P(AUB)'=2/15
Step-by-step explanation:
According to the Question,
Given That, A and B be two independent events. If P(A)=3/5 and P(B')=1/3.So, P(B)=1-P(B') ⇒ P(B)=1-(1/3) ⇔ P(B)=2/3
The Product Rule of Probability says For independent events P(A∩B)=P(A)×P(B)P(A∩B)=3/5 × 2/3 ⇒ P(A∩B)=2/5
We know, P(AUB)=P(A)+P(B)-P(A∩B)Thus, P(AUB)= 3/5 + 2/3 - 2/5
P(AUB)=1/5 + 2/3
P(AUB)=(3+10)/15 ⇔P(AUB)=13/15
Now, The Value Of P(AUB)'=1-P(AUB) ⇔ 1 - 13/15 ⇒ P(AUB)'=2/15
What is the volume, in cubic feet, of a rectangular prism with a height of 2 feet, a

Alana, a talk show host, invited The studio audience to voice their opinions on raising The driving age. Of the 10 audience members who chose to speak, seven of them were against the idea. Is this sample of the audience members likely to be biased. Yes or no please help fast !!!
Answer:
they might be since they could be like 16 and if it was raised they couldn't drive any more
Answer:
Yes, there is a high chance that this sample is biased since our pool of participants is not random.
Step-by-step explanation:
The population from which the talk show host drew is not representative of the entire country's population. Being a part of the live studio audience, these viewers are not considered a random sample and may be influenced by the opinions of the talk show due to response bias, specifically a desire to please bias.
