Answer: x=6
Y=6
Step-by-step explanation:
Using the elimination method
3x+5y=48.....equ1
-3x+5y=12......equ2
Add equation 1 &2
3x+5y=48
+
-3x+5y=12
Answer =
10y=60
Y=60/10
Y=6
Substitute for y in equation 1
3x+5y=48
3x+5(6)=48
3x+30=48
3x=48-30
3x=18
X=18/3
X=6
Therefore,
X= 6
Y= 6
Answer: x=6
Step-by-step explanation:
Let's solve your system of equations by elimination.
3x+5y=48;−3x+5y=12
Steps:
3x+5y=48
−3x+5y=12
Add these equations to eliminate x:
10y=60
Then solve
10y=60
for y:
10y/10=60/10
(Divide both sides by 10)
y=6
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
3x+5y=48
Substitute
6 for y in 3x+5y=48:3x+(5)(6)=48
3x+30=48
(Simplify both sides of the equation)
3x+30+−30=48+−30
(Add -30 to both sides)
3x=18
3x/3=18/3
(Divide both sides by 3)
x=6

What is the mode of the following set of numbers? 15, 20, 18, 20, 15, 20 A 20 B 18 C 5 D 19 .
Answer:
A
Step-by-step explanation:
Mode is the one that appears the most. The number that is there the most is 20 that makes it the mode.
The correct answer is A. 20.
To find the mode of a set of numbers, one must identify the number that appears most frequently in the list. In the given set of numbers: 15, 20, 18, 20, 15, 20, we can see that the number 20 appears three times, which is more frequent than any other number in the set. The number 15 appears twice, while the numbers 18 and 20 each appear once. Since 20 is the number with the highest frequency, it is the mode of the set.
Therefore, the mode of the given set of numbers is 20.

Options
What kind of metal are the coins made of?
Bronze (8700 kg per cubic meter)
Silver (10500 kg per cubic meter)
Lead (11300 kg per cubic meter)
Gold (19300 kg per cubic meter)
Answer:
Gold
Step-by-step explanation:
Density is mass per unit volume of an object hence calculated as
d=m/v
Where m is the mass of an object, v is the volume and d is rhe density.
Substituting 4825 Kg for m and 0.25 m3 for v then
D=4825/0.25=19300 kg/m3
From the options given, this density is equivalent to that of gold.
Marty and Juan took turns driving a cargo truck. The ratio of the miles Marty drove to the miles Juan drove is 6 to 7. Juan drove 150 more miles than Marty. How many miles did Marty and Juan drive in all?
The total miles are 1950 miles. Marty drove 900 miles and Juan drove 1050 miles, if the ratio of the miles Marty drove to the miles Juan drove is 6 to 7 and Juan drove 150 more miles than Marty.
Step-by-step explanation:
The given is,
Ratio of the miles Marty drove to the miles Juan drove is 6 to 7
Juan drove 150 more miles than Marty
Step:1
Calculate the difference in the ratio of the miles Marty drove to the miles Juan drove,
X = 7-6 = 1
Calculate the difference in the miles of Marty drove to the miles of Juan drove,
X = 150 ( Juan drove 150 more miles than Marty)
Equate the Difference between ratio and miles,
From the above values,
X = 150 miles
Step:2
From the ratio of Marty : Juan = 6 : 7
Distance drove by Marty,
= 6X = ( 6 × 150 ) = 900
Distance drove by Marty = 900 miles
Distance drove by Juan,
= 7X = ( 7 × 150 ) = 1050
Distance drove by Juan = 1050 miles
Step:3
Check for solution,
Difference in the miles of Marty drove to the miles of Juan drove
150 = 1050 - 900
150 = 150
Result:
The total miles are is 1950 miles. Marty drove 900 miles and Juan drove 1050 miles, if the ratio of the miles Marty drove to the miles Juan drove is 6 to 7. Juan drove 150 more miles than Marty

The coned shaped room has a height of 15 ft and a radius of 72. Find the volume
Answer:
81430.08
Step-by-step explanation:
Final answer:
The volume of a cone with a height of 15 ft and a radius of 72 ft is found using the formula V = (1/3)πr²h, and the calculated volume is approximately 81457.9 cubic feet.
Explanation:
The question is asking to find the volume of a cone, which has a height of 15 ft and a radius of 72 ft. The formula to calculate the volume of a cone is V = (1/3)πr²h, where 'V' represents the volume, 'r' is the radius of the base, and 'h' is the height of the cone.
To solve for the volume:
V = (1/3)π(72 ft)²(15 ft)
V = (1/3)π(5184 ft²)(15 ft)
V = (1/3)π(77760 ft³)
V = 25920π ft³
Therefore, the volume of the cone is approximately 25920π cubic feet, or when π is approximated as 3.14159, the volume is about 81457.9 cubic feet.

Does it seem fair to you that a hit could be a home run at one stadium but not at others?Explain.
Answer:
No. If standards differ at different sports stadiums, that makes the game unfair for one team or the other. A win at one stadium could be a loss at another. To make the game fair, all facilities should be equal.
Step-by-step explanation:
The unique dimensions and characteristics of each baseball stadium, known as park factors, can impact whether a hit becomes a home run. Although it might seem unfair, it's the same for all teams and is part of the game's complexity. Not only the player's skill but also their knowledge of the park's attributes can influence the outcome of the game.
Explanation:The different sizes and features of baseball stadiums, known as park factors, can impact game dynamics, including whether a hit results in a home run. This is part of the sport's complexity and challenge, as players must adapt their strategies for different venues. It might seem unfair, but it's the same for all teams as they each host and visit various stadiums throughout the season.
In some parks, for example, the distance from home plate to the outfield wall is less, which could make it easier for a hit to become a home run. In contrast, larger parks or those at higher altitudes, where the air is thinner and ball travels further, might be tougher to score a home run.
All these make baseball a fascinating sport, where not only the player's skill but also nuanced aspects like knowledge of the park play an essential role in the outcome of the game. Thus, by definition, a home run is still a successful hit, but where that hit ends up can depend on numerous variables, including the park's attributes.

Barney is an ecologist who studies the change in the tiger population of Siberia over time.
The relationship between the elapsed time t, in decades, since Barney started studying the population, and the
number of tigers, N(t), is modeled by the following function:
N() = 710 (35)
Complete the following sentence about the rate of change in the tiger population. Round your answer to two
decimal places.
The tiger population loses
3/5
of its size every____ decades
The tiger population loses approximately 3/5 of its size every 97.14 decades.
Explanation:The rate of change in the tiger population can be determined by examining the equation N(t) = 710(35). The coefficient of 35 represents the exponential growth factor of the population, which can be interpreted as the population multiplying by 35 over each time period.
To determine the rate of change in terms of the percentage size lost, we can calculate the fractional change by subtracting 1 from the growth factor. In this case, 35 minus 1 equals 34. The percentage size lost can then be calculated by dividing the fractional change by the growth factor and multiplying by 100, giving us (34/35) x 100 = 97.14%.
Therefore, the tiger population loses approximately 3/5 of its size every 97.14 decades.

correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)
Step-by-step explanation:
Here we need to simplify a logarithmic expression and find which expression is equivalent to it . Let's find out:
We have ,
log Subscript 12 Baseline (StartFraction one-half Over 8 w EndFraction) or ,
⇒ [tex]Log_1_2(\frac{\frac{1}{2} }{8w} )[/tex]
We know that : [tex]Log(\frac{a}{b} )=Log(a)-Log(b)[/tex]
⇒ [tex]Log_1_2(\frac{1}{2}) - Log_1_2(8w)[/tex]
We know that : [tex]Log(ab) = Log(a)+Log(b)[/tex]
⇒ [tex]Log_1_2(\frac{1}{2}) -( Log_1_2(8)+Log_1_2(w))[/tex]
Therefore , correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)

The question involves using the quadratic formula where a=1, b=0.0211, and c=-0.0211 to find the two possible values for d.
Explanation:To solve for the values of a, b, c, and d using the given information, we can identify the quadratic formula, which is expressed as:
x = (-b ± √(b² - 4ac)) / (2a)
Given that a = 1, b = 0.0211, and c = -0.0211, we can substitute these into the formula to find the value for x, which could represent d in this case:
x = -0.0211 ± √(0.0211² - 4(1)(-0.0211)) / 2(1)
This simplifies to:
x = -0.0211 ± √(0.00044421 + 0.0844) / 2
From this, we can calculate the two possible values for d.
