The sum of twice a number and a larger number is 145. The difference between the numbers is 55. Let x represent the smaller number and y represent the larger number. Which equations represent the situation? Check all that apply.
Answer:
2x+y=145 and x-y=55.
Step-by-step explanation:
Let x represent the smaller number and y represent the larger number.
ATQ,
The sum of twice a number and a larger number is 145.
2x+y=145 ...(1)
The difference between the numbers is 55.
x-y=55 ...(2)
Hence, the two equations that represent the situation are 2x+y=145 and x-y=55.
Answer:
C. 2x+y=145 D. y-x=55 E. y=x+55

24% is 120% of what number?
Answer:
Step-by-ste24 is 120% of [20]
I don't know if you meant 24 is 120% of x but if that is what you meant, then the answer would be 20. If you meant 24% is 120% of x then x=.2.
24 is 120% of 20 because 20*1.2=24
24% (AKA .24) is 120% of .2 because .2*1.2=.24 and .24=24%

Answer: V = 1649.34
Step-by-step explanation:
The formula for solving the volume of a right cylinder is V = pi r^2h where r = radius and h = height.
We know that radius is half the diameter so r = 5 because the diameter is 10 ft. We already know height = 21 so our equation looks like pi x 5^2 x 21
5^2 = 5 x 5= 25
so pi x 25 x 21 = 1649.34
Answer:
V ≈ 1649.34 ft³
Step-by-step explanation:
Volume of a Cylinder: V = πr²h
Diameter = 2 · radius
Step 1: Define
d = 10 ft
h = 21 ft
Step 2: Substitute and Evaluate
10 = 2r
r = 5
V = π(5)²(21)
V = π(25)(21)
V = 525π
V ≈ 1649.34 ft³

what is the solution for 3х + y = -5
[tex]\tt Step-by-step~explanation:[/tex]
[tex]\tt Solve~for~y:[/tex]
To solve for y, we have to move all of the terms that do not equal to y on one side, and let y be on the other side alone. Do this by subtracting 3x on both sides to cancel it out from the left side and bring it to the right.
[tex]\tt 3x-3x+y=-5-3x\\y=-5-3x\\y=-3x-5[/tex]
[tex]\tt Solve~for~x:[/tex]
To solve for x, we will do the same thing we did to solve for y: move all the terms that do not equal to x to one side, and leave x on another side of the equation. We can do this by first subtracting y from both sides.
[tex]\tt3x+y-y=-5-y\\3x=-y-5[/tex]
Then, we divide all terms by 3 to isolate the x.
[tex]\tt \frac{3x}{3}=x\\\\ \frac{-y}{3}=\frac{-y}{3} \\\\\frac{-5}{3}=\frac{-5}{3}[/tex]
[tex]\tt x=-\frac{y}{3} -\frac{5}{3}[/tex]
[tex]\lare\boxed{\tt Our~final~answer:~y=-3x=5,~x=-\frac{y}{3}-\frac{5}{3} }[/tex]

It's in your genes: Human genetic material (DNA) is made up of sequences of the molecules adenosine (A), guanine (G), cytosine (C), and thymine (T), which are called bases. A codon is a sequence of three bases. Replications are allowed, so AAA, CGC, and so forth are codons. Codons are important because each codon causes a different protein to be created (a) how many different codons (b) how many different codons are there in which all three bases are different (c) the bases A and G are called purines, while C and T are called pyrimidines. How many different codons are there in which the first base is a purine and the second and third are pyrimidines?
Answer:
a. 64
b. 24
c. 16
d. 6/16
e. 1/8
Explanation:
a. How many different codones are there?
Answer: there are 64 different codons
b. How many different codons are there in which all three bases are different?
Answer:there are 24 different codons in which all three bases are different
c. The base A and G are called purines, while C and T are called pyrimidines. How many different codons are there in which first base is purines and second base is pyrimidines
Answer: there are 16 different codons where the which first base is purines and second base is pyrimidines
d. What is the probability that all three bases are different?
Answer: probability of all three bases being different is
Number of codons with three different bases / total number of codons
= 24/64 = 6/16
e. What is the probability that first base is purines and second and third base is pyrimidines?
Answer: prob is number of codons with first base being purine and second and third base being pyrimidines / total number of codons
= 8/64 = 1/8

Write the following expression in exponential form: ^8√x^3
Answer: x^(3/8)
====================================================
Explanation:
The rule we use is
[tex]\Large \sqrt[n]{x^m} = x^{m/n}[/tex]
This allows us to go from root form to exponent form, and vice versa.
The index of the root is the denominator of the fractional exponent.
In this case, m = 3 and n = 8, so,
[tex]\Large \sqrt[8]{x^3} = x^{3/8}[/tex]
Answer:
x^(3/8)
Step-by-step explanation:
Your teacher is giving out fruit for lunch. A paper bag contains 4 apples, 6 pears, and 8 oranges. What is the probability you will pick an orange at random? What is the complement to this event? What is the probability of the complement? Which fruit is more likely to be chosen?
Answer:
What is the probability you will pick an orange at random? 4/9
What is the complement to this event? Pulling either an apple or a pear from the bag
What is the probability of the complement? 5/9
Which fruit is more likely to be chosen? Orange
The probability you will pick an orange at random is 4/9, the complement event is taking an apple or a pear out of the bag, and the probability of complement event is 5/9, and the fruit is orange.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have the total number of fruits = 4+6+8 = 18
The probability you will pick an orange at random = 8/18 = 4/9
Complement of the above event: Taking an apple or a pear out of the bag
The probability of the complement
P = 1 - 4/9 = 5/9
As the probability of the choosing an orange is greater than others, so the orange is the fruit which is more likely to be chosen.
Thus, the probability you will pick an orange at random is 4/9, the complement event is taking an apple or a pear out of the bag, and the probability of complement event is 5/9, and the fruit is orange.

What is the volume of a cone with a radius of 4 centimeters and a height of 5 centimeters? please help
Answer:
V = [tex]\frac{80\pi }{3}[/tex]
Step-by-step explanation:
Using the equation for finding the volume of a cone
V = [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
Were "V" is Volume, [tex]\pi[/tex] is pi, r² is radius to the second power, and [tex]\frac{h}{3}[/tex] is height divided by 3.
We can fill in the missing components to find "V" as in for Volume.
V = [tex]\pi[/tex]4²[tex]\frac{5}{3}[/tex]
Now let's simplify
V = 16[tex]\pi \frac{5}{3}[/tex]
Now simplify for the last time
V = [tex]\frac{80\pi }{3}[/tex]
