during the summer you work 30 hours per week at a gas station and earned $8.75 per hour. You also work as a landscaper for $11 per hour and your work as many hours as you want. You want to earn a total of $400 per week. How many hours mostly work as a landscaper?
Answers
To earn a total of $400 per week, considering you already earn $262.50 working 30 hours a week at a gas station, you need to make up the rest ($137.50) working as a landscaper. This equates to approximately 12.5 hours of work a week at an hourly rate of $11.
Explanation:The nature of the question is mathematical, specifically relating to linear equations. Initially, we know you're earning $8.75 per hour from your job at the gas station, working 30 hours a week, which gives you a total of $8.75 * 30 = $262.50 per week. Your goal is to earn $400 in total per week. Therefore, your earnings from the landscaping job need to make up the difference, which is $400 - $262.50 = $137.50.
Next, to find out how many hours you need to work as a landscaper, we divide that by the landscaper's hourly wage of $11, so $137.50 / $11 = 12.5 hours approximately. Hence to meet your target of $400 per week, you need to work about 12.5 hours as a landscaper, in addition to your 30 hours at the gas station each week.

3x - 2 (x + 3) = 4x - 7
Answers
____________________________________________________
Given: " 3x − 2 (x + 3) = 4x − 7 " ; Solve for "x" ;
____________________________________________________
Start with the following term on the "left-hand side" of the equation:
" - 2 (x + 3) " ;
____________________________________________________
Note the "distributive property of multiplication" :
____________________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
____________________________________________________
As such,
" -2 (x + 3) = -2(x) + -2(3) = -2x + (-6) = -2x − 6 ;
____________________________________________________
So, we can rewrite our equation:
____________________________________________________
" 3x − 2 (x + 3) = 4x − 7 " ; substituting: " -2x − 6" (for " −2 (x + 3)" ; as follows:
____________________________________________________
3x − 2x − 6 = 4x − 7 ;
___________________________________________________
On the left-hand side off the equation;
________________________________
We can combine the "like terms" ; as follows:
3x − 2x = 1x = x ; and rewrite the equation:
__________________________________
x − 6 = 4x − 7 ;
____________________________________
We can subtract "4x" from each side of the equation; and add "6" to each side of the equation:
____________________________________
x − 6 − 4x + 6 = 4x − 7 − 4x + 6 ;
to get: -3x = -1 ;
____________________________________
Now, we divide EACH SIDE of the equation by "-3" ; to isolate "x" on ONE SIDE OF THE EQUATION; and to solve for "x" ;
____________________________________
-3x / 3 = -1/-3 ;
____________________________________
to get: x = ⅓ .
_____________________________________
→ Now, let us check our answer by plugging in "⅓" for all values of "x" in the ORIGINAL GIVEN EQUATION; to see if the equation holds true:
_____________________________________________________
→ 3x − 2 (x + 3) = 4x − 7 ;
→ [3 * (⅓) ] − 2 [ (⅓) + 3) = ? 4(⅓) − 7 ?? ;
→ (1) − 2(3 ⅓) =? (⁴/₃) − 7 ?? ;
→ (1) − 2(3 ⅓) =? (⁴/₃) − 7 ?? ;
→ (³/₃) − 2(¹⁰/₃) =? (⁴/₃) − (²¹/₃) ?? ;
→ (³/₃) − (²⁰/₃) =? (⁴/₃) − (²¹/₃) ?? ;

Answer:
[tex]x=20[/tex]
Step-by-step explanation:
We have been a triangle has one angle measuring [tex]3x[/tex] degrees the second angle measures [tex]2x+20[/tex] degrees and the third angle measures [tex]4x-20[/tex] degrees. We are asked to find the value of x.
We know that all interior angles of a triangle add up-to 180 degrees.
[tex]3x+2x+20+4x-20=180[/tex]
Combine like terms:
[tex]3x+2x+4x-20+20=180[/tex]
[tex]9x=180[/tex]
Divide both sides by 9:
[tex]\frac{9x}{9}=\frac{180}{9}[/tex]
[tex]x=20[/tex]
Therefore, the value of x is 20 for our given triangle.
Berto has $12 to put gas in his car. If gas costs $3.75 per gallon, which ordered pair relating number of gallons of gas, x, to the total cost of the gas, y, includes the greatest amount of gas Berto can buy?
Answers
Good Luck! :D
Answer:
The required ordered pair is (3.2,12).
Step-by-step explanation:
Let the x be the relating number of gallons of gas and y be the total cost of the gas.
It is given that the cost of gas is $3.75 per gallon. Total cost of x gallons is
[tex]y=3.75x[/tex]
Berto has $12 to put gas in his car.
[tex]y\leq 12[/tex]
[tex]3.75x \leq 12[/tex]
Divide both sides by 3.75.
[tex]x \leq 3.2[/tex]
The maximum number of gallons of gas is 3.2 and the total cost of the gas is 12.
Therefore the required ordered pair is (3.2,12).

Write 28 as a product of its prime factors write the factors in order, from smallest to largest
Answers
2 x 2 = 4
4 x 7 = 28
hope this helps
Final answer:
To express 28 as a product of its prime factors, you would write [tex]28 = 2^2 \times 7[/tex], where 2*2 represents 2 multiplied by itself and 7 is a prime number.
Explanation:
To write 28 as a product of its prime factors, we begin by finding the smallest prime number that divides 28. Since 28 is an even number, we know it's divisible by 2. So we start with 2 and keep dividing:
28 ÷ 2 = 14
14 ÷ 2 = 7
Now, 7 is a prime number and cannot be divided further except by 1 and itself. So, we end up with:
28 = 2 × 2 × 7
We can also express this using exponents:
28 = 2² × 7
These are the prime factors of 28, written in order from smallest to largest.
Are points A, C, D, and F coplanar? Explain.

b) No; three lie on the same face of the pyramid and the fourth does not.
c) Yes; they all lie on the same face of the pyramid.
d) No; they are not on the same line.
Answers
The points A, C and D form a triangle which is the front face you see in the pyramid. Point F is not on this triangle at all. Point F is towards the back at the base of the pyramid away from this front face. So we consider A,C,D,F collectively as a whole to be not coplanar. If we ignored the point F, then we can say that A,C,D are coplanar.
The points A, C, D, and F are not coplanar points.
What are the coplanar points?The points that are on the same plane is called coplanar points.
Here, a square pyramid is drawn on a plane.
Points A, C, D are three vertices of a side of the pyramid.
Hence, points A, C, D are coplanar.
However, the point F is the vertex of the opposite side triangle of the square pyramid.
Therefore, the point F is not on the same plane of points A, C, and D.
Hence, points A, C, D, and F are not coplanar.

how do u decompose 122 and 3 in math
Answers
Decomposing 3 is more simple because it is a single digit. It will look like this: 3, because all you are representing is the ones unit. However, some instructors will want you to break a single digit into its various addends, so if your instructor is asking you to do this, it will look like this: 3+0=3, 2+1=3, 1+2=3, 0+3=3.
Final answer:
Decomposing the number 122 involves breaking it into place values: 100 + 20 + 2. The number 3 is prime and can't be decomposed further except when used as an exponent, as in 3² = 9. Decomposing non-integer exponents, suggested by 3¹.⁷, is complex and often requires a calculator for exact results.
Explanation:
To decompose the number 122 in mathematics means to break it down into parts that can be more easily understood or used in calculations. One common method of decomposition is to break the number into its place values. For 122, this would be 100 + 20 + 2. As for the number 3, it is a prime number and cannot be decomposed into other numbers, except if we are talking about an operation such as factoring 3², which would be 3 x 3 or 9.
When dealing with exponents, as in the expression 3¹.7, we face a different type of decomposition. This is not a standard notation, and it might be a typo, as decimal exponents are not normally used. However, if we try to make sense of it, we could assume the intention was to represent a non-integer exponent, which might occur in expressions like [tex]3^{(17/10)[/tex], which would have to be calculated using a calculator or logarithms for a precise result. The decomposition in such scenarios is not as straightforward as with integer exponents like in 3´, which is simply 3 x 3 x 3 x 3.

Rodrigo researched the number of pets owned in the U.S. and displayed his results in the bar graph shown. in his research, he found that $7,737.6 million was spent on annually on veterinary visits for the dogs and $5,913 million was spent annually on visits for cats. How much more was spent, on average, by each person for dogs than cats?
Answers
Answer:
$29 million is spent more by each person for dogs than cats.
Step-by-step explanation:
Amount spent on visits for the dogs = $7,737.6 millions.
Number of dogs owned = 31.2 millions (by bar graph)
∴ On average amount spent on each person = [tex]\frac{7,737.6}{31.2} = $248 millions [/tex]
Amount spent on visits for the cats = $7,737.6 millions.
Number of cats owned = 27 millions (by bar graph)
∴ On average amount spent on each person = [tex]\frac{5913}{27} = $219 millions [/tex]
Thus, on average, by each person amount spent for dogs than cats = $248 millions - $219 millions = $29 millions.
