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.
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.

The Johnsons framed a family picture to hang on the wall. The perimeter of the frame is 72 inches. Use the formula p= 2l ÷ 2w to find the length of the frame if the width is 14 inches
Answers
length of the frame = ?
width of the frame = 14 inches
formula to use is
p = 2l ÷ 2w
now put the values of width and perimeter
72 = 2l ÷ 2(14)
72 = 2l ÷ 28
72 x 28 = 2l
2016 = 2l
l = 2016/ 2
l = 1008 inches
length of the frame is 1008 inches
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).

What is the average height of the ocean at low tide with respect to sea level?
Answers
The average height of the ocean is -2.
What is Average?Average The arithmetic mean is calculated by adding a set of integers, dividing by their count, and then taking the result.
For instance, the result of 30 divided by 6 is 5, which is the average of 2, 3, 3, 5, 7, and 10.
Averages are used to condense a vast number of data points into a single value. It is a visual depiction of all the data set's accessible numbers.
Given data:
Monday a.m.: −4
Monday p.m.: −6
Tuesday a.m.: −3
Tuesday p.m.: −1
Wednesday a.m.: 0
Wednesday p.m.: 2
Thursday a.m.: −1
Thursday p.m.: −3
So, the average height of the ocean at low tide
=(-4 + (-6)+ (-3)+ (-1) + 0+ 2 + (-1) + (-3))/8
= (-18 + 2 ) / 8
= -16 /8
= -2
Hence, the average height of the ocean is -2.

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) ?? ;
→ ⁽³ ⁻²⁰⁾/₃) =? ⁽⁴⁻²¹⁾/₃) ??

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.

The slope is undefined for figure 2.
In general, when the x-values or x-coordinates is the same for both points, the slope is undefined.
For example, let us try to get the slope for a line passing through the points (1, 3) and (1, 9)
Let x₁ = 1 , y₁ = 9 and x₂ = 1 and y₂ = 3
Slope, m = (y₂ − y₁)/((x₂ − x₁)
m = (3 − 9)/(1 − 1)
m = -6/0, which is undefined.
