Solve this equation or formula for the variable indicated.
Solve for t: 7t = x
Greetings!
In this literal equation, the only thing we will have to do is get t by itself. In order to do that we will perform the opposite relation it has with 7, which is division, on both sides.
The answer will be x divided by 7 equals t, x / 7 = t.
Hope this helps!

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!

(a) About what percent of calls lasted 30 minutes or
more?
(b) Estimate the interquartile range (IQR) of the
distribution.
Answer:
a) 35%
b) 19 minutes
Step-by-step explanation:
The graph for this question is attached in the image below.
Part a) Percent of calls that lasted 30 minutes or more
As seen in the graph, the x-axis represent the duration of the call in minutes and y-axis represent the cumulative frequency of the calls.
From the graph we can see that the cumulative frequency against the point 30 minutes is about 65%. This means, 65% of the calls lasted for less than 30 minutes.
Since, out of 100%, 65% of the calls lasted for less than 30 minutes, the percentage of call that lasted for 30% or more would be:
100% - 65% = 35%
This means, 35% of calls lasted 30 minutes or more.
Part b) The interquartile range (IQR) of the distribution.
Interquartile range is defined as the difference of the 3rd Quartile and the 1st Quartile.
3rd Quartile is the point, below which 75% of the data values are present.
1st Quartile is the point, below which 25% of the data values are present.
So, from the cumulative frequency graph we have to look for the values on time axis against the cumulative frequency of 25% and 75%.
The amount of time against 25% cumulative frequency is approximately 13 minutes.
So, 1st Quartile = 13 minutes
The amount of time against 75% cumulative frequency is approximately 32 minutes.
So, 3rd Quartile = 32 minutes
Therefore,
IQR = 3rd Quartile - 1st Quartile
IQR = 32 - 13
IQR = 19 minutes
The interquartile range (IQR) of the distribution is 19 minutes.

The angles of a rectangle are equal.
always
sometimes
never
Answer: A rectangles angles are always equal.
Step-by-step explanation:
Suppose you have a rectangle, four sides, two pairs of parallel lines. in order to be a rectangle, the quadrilateral has to have equal angles, similar to a square, if they didn't, they could be a trapezoid, which is not a rectangle, because it only has one pair of parallel lines.
Hope this helps!
Answer:
They are always equal
Step-by-step explanation:
Because they all have equal sides they can be measured to confirm that the sides are equal.

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

Harry needs 21 square meters of fabric for every 6 wizard cloaks he makes. How many cloaks could he make with 7 square meters of fabric
Answer: 2
Step-by-step explanation:
First, set up a proportion based on the amount of square meters over the number of cloaks he can make:
21/6 = 7/x
Cross multiply to get your next proportion and result with this:
21x = 42
Divide both sides by 21 (always divide the side with the variable):
21x/21 = 42/21
Cancel out the 21 (it's being divided by 21 so that makes it equivalent to 1 so you wind up with just x)
x = 2
Answer: 2
Step-by-step explanation:
Given : Harry needs 21 square meters of fabric for every 6 wizard cloaks he makes.
Using Unitary method , The number of cloaks can be made in 1 square meter fabric will be :-
[tex]6\div21=\dfrac{6}{21}=\dfrac{2}{7}[/tex]
Now , the number of cloaks made in 7 square meters of fabric will be :-
[tex]\dfrac{2}{7}\times7=2[/tex]
Hence, the number of cloaks made in 7 square meters of fabric =2

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)

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

If f x = x2 + 2x − 5 and g x = 2x + 4, what is (f · g)(x) ?
[tex]\((f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \)[/tex].
To find [tex]\((f \cdot g)(x)\)[/tex], you need to multiply the functions \(f(x)\) and \(g(x)\).
Given:
[tex]\[ f(x) = x^2 + 2x - 5 \]\[ g(x) = 2x + 4 \]To find \( (f \cdot g)(x) \), multiply \( f(x) \) and \( g(x) \):\[ (f \cdot g)(x) = f(x) \cdot g(x) \]\[ (f \cdot g)(x) = (x^2 + 2x - 5) \cdot (2x + 4) \][/tex]
Now, use the distributive property to expand the expression:
[tex]\[ (f \cdot g)(x) = 2x^3 + 4x^2 + 4x^2 + 8x - 10x - 20 \]\[ (f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \][/tex]

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.

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.
