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).
Find the distance between M(–2, 3) and N(8, 2).
a) 10
b) (image #1)
c) 8
d) (image #2)
Answers
The answer is b) (image #1)
The distance between points M(-2,3) and N(8,2) is sqrt(101) which is calculated using the distance formula. None of the provided choices match this answer.
Explanation:The subject of this question is in the field of Mathematics, specifically involving the use of the Distance Formula in a coordinate plane. The distance between two points in a plane, Point M(-2, 3) and Point N(8, 2) can be calculated using the formula:
D = sqrt[(x2-x1)² + (y2-y1)²]
Substituting the given coordinates, we get:
D= sqrt[(8-(-2))² + (2-3)²]
D= sqrt[(10)² + (-1)²] = sqrt[100+1] = sqrt[101]
None of the provided options in the choices seem to be correct, assuming 'sqrt[101]' is not among the image choices.

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.
If the expression is 3x+1 is equal to -7 for the some value of x, Then what is the value of the expression 6x+5 for the same value of X? Show the work that leads to your solution

3x = -8 subtract 1 from both sides to separate the x
X= -8/3 divide both sides by 3 to find the value of x
6(-8/3) + 5 replace x with the value of x that you found in the other equation
16 + 5 multiply 6 * (-8/3)

Are points A, C, D, and F coplanar? Explain.
a) Yes; they all lie on plane P.
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.

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
