The sum of two numbers is 12. Three times the smaller number increased by the larger number is 20 . Find the numbers .Write the solution
Answer:
In these types of algebra problems where we are given numbers that are "unknown" and asked to find them, it is a good idea to give them names.
Let the larger number be X.
Let the smaller number be Y.
If the larger number is three times the smaller number, we can use this information to write an equation, using our labels for the two unknown numbers. See how I translate this sentence into an equation:
The larger number is three times the smaller number.
X = 3 * Y
X = 3*Y
We've got one equation down. Since we have two variables, we're going to need two equations to solve for both of them.
The sum of two numbers is twenty-four.
X + Y = 24
X+Y = 24
But, from our previous equation, we know that X is the same as 3*Y. This allows us to substitute "X" with "3*Y" in our second equation since the two are equal according to the first equation.
(3*Y) + Y = 24.
3Y + Y = 24
4Y = 24
4Y / 4 = 24/4
Y = 6
Now we've got the value of the smaller number. Let's plug it into our first equation,
X = 3*Y.
X = 3*(6)
X = 18
We can check our work by plugging both values into both equations and seeing if they work out:
6+18 = 24
6*3 = 18
So our bigger number is 18, and our smaller number is 6.

Student council is selling candy bars to raise money for the for Halloween dance because the student council $173 to rent a booth and $.45 for each candy bar. They sell the candy bars for $5 each. How many candy bars mostly so so that the money they spend is the same amount as they make
Answer:
The student council needs to sell 38 candy bars so that the money they spend is the same amount as they make.
Step-by-step explanation:
You have to write an expression where the price they spent that includes the money to rent a booth and the amount paid for each candy bar for the number of candy bars purchased is equal to the money spent that is the price at which they sell the candy bars for the number of candy bars sold:
173+0.45x=5x, where x is the number of candy bars
Now, you can solve for x:
173=5x-0.45x
173=4.55x
x=173/4.55
x=38
According to this, the answer is that the student council needs to sell 38 candy bars so that the money they spend is the same amount as they make.
The function f(x) = x is translated using the rule (x, y) - (x - 6, y + 9) to create A(x).
Which expression describes the range of A(x)?

It seems the correct function you need to mention is f(x) = sqrt x
so, I am assuming [tex]f(x) = \sqrt{x}[/tex] and will solve the question based on it.
Answer:
Check the explanation
Step-by-step explanation:
Given the function
[tex]f(x) = \sqrt{x}[/tex]
As the function is translated according to the rule
(x, y) → (x - 6, y + 9)Translation of the function [tex]f(x) = \sqrt{x}[/tex] 6 units to the left will bring the function
[tex]g(x) = \sqrt{x+6}[/tex]
Translation of the function [tex]g(x) = \sqrt{x+6}[/tex] 9 units up will bring the function
[tex]A\left(x\right)=\sqrt{x+6}+9[/tex]
Determining the range of [tex]A\left(x\right)=\sqrt{x+6}+9[/tex]
As we know that the range is the set of dependent values for which the function is defined.[tex]\mathrm{The\:range\:of\:an\:radical\:function\:of\:the\:form}\:c\sqrt{ax+b}+k\:\mathrm{is}\:\:f\left(x\right)\ge \:k[/tex]
[tex]k=9[/tex]
[tex]f\left(x\right)\ge \:9[/tex]
so
[tex]\mathrm{Range\:of\:}\sqrt{x+6}+9:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:9\:\\ \:\mathrm{Interval\:Notation:}&\:[9,\:\infty \:)\end{bmatrix}[/tex]
Therefore, the expression describes the range of A(x) will be:
[tex]f\left(x\right)\ge \:\:9\:or\:y\:\ge \:\:\:9[/tex]

Calculate the speed of a 5.2 kg object that possesses 26.1 J of kinetic energy
The speed of object is 3.68m\s.
Given that,
Mass of the object = 5.2 kg,
Object that possesses 26.1 J of kinetic energy.
We have to find,
The speed of the object.
According to the question,
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
If work, which transfers energy, is done on an object by applying a net force, the object speeds up and there by gains kinetic energy.
Then, The formula of kinetic energy is given as,
[tex]K.E = \frac{1}{2} mv^{2}[/tex]
Where, m = mass of the object
And v = speed of the object
Therefore, The speed of the object calculated as.
[tex]KE = \frac{1}{2} mv^{2} \\\\26.1 = \frac{1}{2} \times 5.2\times v^{2} \\\\26.1 = 2.6 \times v^{2} \\\\\frac{26.1}{2.6} = v^{2} \\\\v^{2} = 10.1\\\\v = \sqrt{10.1} \\\\v = 3.68[/tex]
Hence, The speed of object is 3.68m\s.

Sales Daria sells televisions. She earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Daria sells 15 televisions with extended warranties, she earns \$1,500 . How much is the fixed amount Daria for each television? The fixed amount Daria ears for each television she sells is
Answer:
$70
Step-by-step explanation:
Daria's total income = fixed income + variable income
Let
Daria's Fixed income = x
additional $30 if the buyer gets an extended warranty
Daria's variable income = 30s
Where,
s = number of televisions with extended warranties she sells
If Daria sells 15 televisions with extended warranties, she earns \$1,500. Find her fixed income
Daria's total income = fixed income + variable income
1500 = x + 30(15)
1500 = x + 450
1500 - 450 = x
1,050 = x
x = $1,050
Daria's total fixed income = $1,050
How much is the fixed amount Daria for each television?
Fixed income per television = Total fixed income / number of television sold
= 1050 / 15
= 70
Fixed income per television = $70

The probability that it will rain on 'Hari Merdeka' is 2/15.Find the probability that will be no rain on 'Hari Merdeka'.
The probability it will rain of Hari Merdeka is 2/15. Since you are finding the probability that will be no rain on Hari Merdeka, you also need to find the part of 15/15 that is not 2/15. You can do this by subtracting.
15/15-2/15=13/15.
The probability that will be no rain on Hari Merdeka is 13/15.

Coach Dan has decided to surprise the athletic department's team members with new hats. Hats are sold in boxes of 18. If there are a total of 168 team members he would like to buy hats for, how many boxes would he have to order? Explain your reasoning.
Answer:
10 boxes
Step-by-step explanation:
Let's say Coach Dan orders b boxes.
Then since there are 18 hats in each box, we will have a total of 18b hats.
We would like to buy enough for 168 team members, so let's set 18b equal to 168 and solve for b:
18b = 168
b = 168/18 = 9.33
Well, we clearly need at least 9 boxes, but it's not possible to have 0.33 of a box. Thus, we must order one more box for a total of 10 boxes.

a. Their corresponding sides are congruent.
b. Their corresponding angles are in a ratio of 1:5
c. Their areas have a ratio of 1:5.
d. their perimeters are in a ratio of 1:5
Answer:
c
Step-by-step explanation:

d. their perimeters are in a ratio of 1:5
Explaination
A is untrue because the sides have the ratio of 1:5, explained in the quastion, so they are not equal/congruent.
B is untrue because the angles are the same in both triangles because the triangles are similar, mentioned in the question.
C is untrue because the ratio of area is squared to the ratio of the perimeter, so the actual areas would be 1:25.

In a 30°-60°-90° triangle, what is the length of the longer leg when the length of the hypotenuse is 18 inches?
9✓2 in.
9✓3in.
18✓2 in.
18✓3in.
Answer:
9sqrt(3) in.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is:
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
If the short leg measures 1, then the hypotenuse measures 2.
The length of the hypotenuse is twice the length of the short leg.
The length of the long leg is sqrt(3) times the length of the short leg.
If the hypotenuse measures 18 in., then the short leg measures 9 in.
Then the long leg measures 9sqrt(3) in.
The length of the longer leg is 9√3 inches.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, the length of the hypotenuse is 18 inches.
The ratio of the lengths of the sides of a 30°-60°-90° triangle is:
Short leg: long leg: hypotenuse = 1 : √3 : 2
Since the hypotenuse is 18 inches, it follows that the value of 2 is 18:
2 = 18
1= 9
√3 = 9√3
Hence, the length of the longer leg is 9√3 inches.
