The table shows the weight of a newborn infant for its first year. During which three-month period was the infant's weight gain the greatest?
0 Months: 7 1/4 lb
3 Months: 12 1/2 lb
6 Months: 16 5/8 lb
9 Months: 19 4/5 lb
12 Months: 23 3/20 lb
Answer:
12,9,6
Step-by-step explanation:
12=23 3/20. 9=19 4/5. 6=16 5/8.
The infant's weight was gain the greatest during (0 - 3 Months) three-month period.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
The weight gain during (0 - 3 Months) three-month period
⇒ 12 1/2 - 7 1/4 = 25/2 -29/4 = 12.5-7.25 = 5.25 lb
The weight gain during (3 - 6 Months) three-month period
⇒ 16 5/8 - 12 1/2 = 16.625 - 12.5 = 4.125 lb
The weight gain during (6 - 9 Months) three-month period
⇒ 19 4/5 - 16 5/8 = 19.8 - 16.625 = 3.175 lb
The weight gain during (9 - 12 Months) three-month period
⇒ 23 3/20 - 19 4/5 = 23.15 - 19.8 = 3.35 lb
Therefore, the infant's weight was gain the greatest during (0 - 3 Months) three-month period.

A vender is loading candybars into a vending machine. Each slot holds 130cm of candy barsand each candy bar is 1.5cm thick, how many bars will fit.
Answer:
86
Step-by-step explanation:
since the slot is 130 cm thick you divide that by the thickness of the candy bar 130/1.5 and then you get 86.6666666.....which rounds to 86 because the slot is not thick enough for another candy bar. good luck on whatever you needed this for!

The length of a rectangle is 2cm longer than the width. The perimeter is 52cm. What is the length and width of the rectangle?
Answer:
Width = 12 cm
Length = 14 cm
Step-by-step explanation:
Rectangle:
Let the width = x cm
So, the length = (x+2) cm
Perimeter = 52 cm
2 *(l+b) = 52
2 *(x+2 + x) = 52
2 * ( 2x + 2) = 52
2x + 2 = 52/ 2
2x + 2 = 26
2x = 26- 2
2x = 24
x = 24/2
x = 12
Width = 12 cm
Length = 14 cm
Given the function f(x) = 3x + 1 and the linear function g(x), which function has a greater value when x = 3?
f(x) is greater.
g(x) is greater.
f(x) and g(x) are the same when x = 3.
g(x) is undefined when x = 3.
Answer:
f(x) is greater.
Step-by-step explanation:
if you replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9
The function that has a greater value when x = 3 is option A: f(x) is greater.
What is the functionThe function [tex]\(f(x) = 3x + 1\)[/tex] is a linear function with a slope of 3 and a y-intercept of 1. The function[tex]\(g(x)\)[/tex] is not explicitly provided in your question, so we don't have information about its slope or intercept.
To determine which function has a greater value when x = , we need to evaluate both functions at x = 3 and compare their values.
So, when one replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9

Use the commutative property of addition to write an equivalent algebraic expression
Answer:
9(x+5)=9(5+x)
Step-by-step explanation:
This is tricky because you were probably thrown off by the multiplication step from the parentheses. Since the question wants you to demonstrate your knowledge of the commutative property of addition, you will only worry about inside the parentheses.
So, the commutative property is basically just moving numbers/variables around the addition sign to show that the answer will remain the same either way.
Because of this, we can simply move the (x+5) around to (5+x).
Final answer: 9(x+5)=9(5+x)
Which of the following expressions are equivalent to 3/11
Answer:
-3/-11
Step-by-step explanation:
2 negitives make a positive and plus i got it right
The Equivalent Expressions fractions to 3/11 from the options provided are 9/33 and 15/55, as they can be obtained by multiplying the numerator and denominator of 3/11 by the same number.
To find equivalent fractions to 3/11, you would need to multiply or divide both the numerator and denominator by the same number. We need to identify options that result from such actions on 3/11.
Option A: 6/21: No multiplicative or dividing relation can be found between 3 and 6 or 11 and 21, so this option is invalid.
Option B: 9/33: This is obtained by multiplying both numerator and denominator of 3/11 by 3. So, this option is valid.
Option C: 15/55: This is obtained by multiplying both numerator and denominator of 3/11 by 5. So, this option is valid.
Option D and E: There is no such multiplier or divider that can obtain these fractions from 3/11, so both are invalid.
Thus, the equivalent expressions to 3/11 from the options provided are options B (9/33) and C (15/55).

The circumference (C) of the base of a grain silo is 160 feet. To the nearest tenth, what is the radius (r) of the silo? (C = 2πr)
A) 18.5 feet
B) 25.5 feet
C) 50.9 feet
D) 64.8 feet
Answer: B) 25 feet
Step-by-step explanation:
The formula to find the circumference of a circle is given by :-
[tex]C=2\pi r[/tex], where r is the radius of the circle. (1)
Given : The circumference (C) of the base of a grain silo is 160 feet.
Then,by using (1), we have
[tex]160=2(3.14)(r)\\\\\Rightarrow\ r=\dfrac{160}{2\times3.14}\\\\\Rightarrow\ r=25.4777070064approx25.5\text{ feet }[/tex]
Hence, the radius (r) of the silo= 25 feet
Stan's, Marks and Wayne's ages are consecutive whole numbers. Stan is the youngest, and Wayne is the oldest. The sum of their ages is 102. Find their ages
Answer: Wayne is 35, Mark is 34, and Stan is 33.
33+34+35 = 102
Stan is 33 years old, Mark is 34 years old, and Wayne is 35 years old.
Explanation:Let's solve the problem step by step:
Let's assume Stan's age to be x.
According to the given information, Mark's age is one more than Stan's age, so Mark's age is x + 1.
Similarly, Wayne's age is one more than Mark's age, so Wayne's age is (x + 1) + 1 = x + 2.
Now we know that the sum of their ages is 102, so:
x + (x + 1) + (x + 2) = 102
Combining like terms, we get:
3x + 3 = 102
Simplifying the equation, we get:
3x = 99
Dividing both sides by 3, we get:
x = 33
Now we can substitute the value of x in the previous equations:
Stan's age = 33
Mark's age = 33 + 1 = 34
Wayne's age = 34 + 1 = 35
So, Stan is 33 years old, Mark is 34 years old, and Wayne is 35 years old.
Are the sets equivalent? A= {Larry,Moe,Curly,Shemp}. B= {Posh, Sporty,Baby,Scary}
Answer:
yes
Step-by-step explanation:
equivalent sets have the same number of members
Sets A and B are not equivalent, have the same cardinality but no common elements in their intersection.
The sets A and B are not equivalent because they have different members.
The cardinality of set A is 4, and the cardinality of set B is also 4, meaning they have the same number of elements.
The intersection of sets A and B is the empty set, as they have no common elements.

Write an equation of the cosine function with the given amplitude, period, phase shift, and vertical shift. amplitude: 2, period = , phase shift = – , vertical shift = –2
Answer:
[tex]y=2\cos(2x+\frac{1}{4})-2[/tex]
or
[tex]y=-2\cos(2x+\frac{1}{4})-2[/tex]
Step-by-step explanation:
[tex]y=a cos(c(x-b))+d[/tex] has:
1) amplitude=|a|
2) phase shift=b
3) period=2pi/c
d) vertical shift=d
--------------------------------------------------
You are given the amplitude is 2. This means a could either be 2 or -2.
You are given phase shift is -1/8. This means b is -1/8.
You are given the period is pi. So we need to solve pi=2pi/c.
pi=2pi/c
Dividing both sides by pi gives:
1=2/c
Multiply both sides by c gives:
c=2
The vertical shift is -2 so d=-2.
The equation could either be:
y=2cos(2(x-(-1/8)))-2
or
y=-2cos(2(x-(-1/8)))-2
Simplifying a little gives:
y=2cos(2x+1/4)-2
y=-2cos(2x+1/4)-2
Write the equation of the line through (3, −1) and parallel to 2x−y=6.
Answer:
2x - y = 7
Step-by-step explanation:
Parallel lines have the same slope and the equation will have the same form
That is
2x - y = c ← c will have different values depending on the point it passes through.
Here the line passes through (3, - 1 ) , thus substituting into the left side
2(3) - (- 1) = 6 + 1 = 7 ← value of c, hence
2x - y = 7 ← equation of line
The line's equation is y = 2x - 7.
What are parallel lines?In geometry, the coplanar straight lines that do not intersect at any point are called parallel lines. The slopes of parallel lines are equal because they are equally inclined with the positive x-axis.
How to solve this problem?The equation of the given line is
2x-y = 6
i.e. y = 2x-6
We know that If the equation of a line can be expressed as y = mx+c, then the slope of this line is m.
So, the slope of this given line is 2.
We can assume that the equation of the line which is parallel to the given line can be written as
y = 2x + c ...(1)
, where c is a constant.
Since this line passes through the point (3, -1), you have to put x = 3 and y = -1 in (1), to get the value of the constant.
Now, c = y - 2x = (-1) - 2*3 = (-1) - 6 = -7
Putting this value in (1), we get
y = 2x - 7
Therefore the required equation of the line is y = 2x - 7.
