Answer:
(7/8 - 4/5)^2 = 9/
1600
= 0.005625
Step-by-step explanation:
Subtract: 7/
8
- 4/
5
= 7 · 5/
8 · 5
- 4 · 8/
5 · 8
= 35/
40
- 32/
40
= 35 - 32/
40
= 3/
40
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by canceling.

In 2 mins., a conveyor belt moves 300 lbs. Of recycle aluminum from delivery truck to a storage area. A smaller belt moves the same quantity of cans the same distance in 18 mins. If both belts are used, find how long it takes to move the cans to the storage area
Answer:
1.8 minutes or 108 seconds
Step-by-step explanation:
The question tells us that the larger belt moves 300 lbs in 2 mins. And this is equal to 150 lb per minute
The question also tells us that a smaller belt moves the same quantity of 300 lbs in 18 mins. And this is equal to an average of 16.667 lb per min.
Both belts will move at a rate of 166.667 lb per min.
So it will take them 300 / 166.667 = 1.8 min or 108 s.
Therefore, the answer is 1.8 min

Answer:
your question is poorly written below is the properly written question
Find a coterminal Angle with measure θ ( -22° ) such that 0° ≤ θ < 360°
answer: 338°
Step-by-step explanation:
To find a coterminal angle of a given angle that falls between 0° and 360° we have to express the angle in terms of 360°
Hence express -22° in terms of 360°
-22° = -360° + 338°
hence the coterminal angle = 338°

Step-by-step explanation:
In a recent election, there were six candidates and 4700 total votes. The circle graph below summarizes the votes by candidate.
The central angle for the Bowerman slice is 36º. What percentage of the votes did Bowerman get? Do not round.
The circle is 360 degrees so,
360 degrees --> 4700 votes
36 degrees ---> x
4700*36 = 360*x
169,200 = 360*x
x= 169,200/360
x= 470
[tex] \frac{470}{4700} = 0.1 = 10\%[/tex]
The difference of a number and 4 is no more than 8
Can someone help!?
Considering the definition of an inequality, the number must be less than 12.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that the difference of a number and 4 is no more than 8.
Being "x" the number you want to know, and considering that the difference is the difference between two numbers or expressions, the inequality that expresses the previous relationship is
x - 4 < 8
Solving:
x < 8 +4
x < 12
Finally, the number must be less than 12.

Step-by-step explanation:

Complete the double number line
The given double number lines represent a linear function between cups of flour (c) and number of batched (n)
Pick any two pairs:
[tex](c_1,n_1) = (\frac{3}{4},1)[/tex]
[tex](c_2,n_2) = (3\frac{3}{4},5)[/tex]
First, calculate the rate of change (i.e. slope, m):
[tex]m = \frac{n_2 - n_1}{c_2 - c_1}[/tex]
[tex]m = \frac{5-1}{3\frac{3}{4} - \frac{3}{4}}[/tex]
[tex]m = \frac{4}{3}[/tex]
So: the equation is:
[tex]n = m(c - c_1) + n_1[/tex]
This gives:
[tex]n = \frac{4}{3}(c - \frac{3}{4}) + 1[/tex]
[tex]n = \frac{4}{3}c - 1 + 1[/tex]
[tex]n = \frac{4}{3}c[/tex]
So, the above represents the relationship between n and c.
To complete the table
When [tex]n = 2[/tex]
Substitute [tex]n = 2[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]2 = \frac{4}{3}c[/tex]
Make c the subject
[tex]c = \frac{3*2}{4}[/tex]
[tex]c = \frac{3}{2}[/tex]
When [tex]n = 3[/tex]
Substitute [tex]n = 3[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]3 = \frac{4}{3} * c[/tex]
Make c the subject
[tex]c = \frac{3*3}{4}[/tex]
[tex]c = \frac{9}{4}[/tex]
When [tex]c=3[/tex]
Substitute [tex]c=3[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]n = \frac{4}{3} * 3[/tex]
[tex]n = 4[/tex]
So, the complete table is:
[tex]c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5[/tex]

Bob, a lawyer, used to charge his clients $220 per hour Recently, he reconsidered his rates and ultimately decided to charge 30% more. Now how much does Bob charge per hour?
Answer:
The Poisson probability distribution gives the probability of a number of events occurring in a fixed interval of time or space if these events happen with a known average rate and independently of the time since the last event. For example, a book editor might be interested in the number of words spelled incorrectly in a particular book. It might be that, on the average, there are five words spelled incorrectly in 100 pages. The interval is the 100 pages.
Answer:
$286 per hour
Step-by-step explanation:
first we have to find out what 30% of $220 is
we do this by multiplying $220 by 0.3
We get $66
then we add the markup value to the initial value
$66 + $220= $286

A square has one
side that measures
6 inches. What is
the perimeter of
the square?
Answer:
24 inches
Step-by-step explanation:
a square has 4 equal sides. if one side is 6, the rest of the sides are also six. perimeter is all the sides added. so 6+6+6+6, or 6*4, equals 24 inches as perimeter.
Figure with four equal sides and four right (90°) angles. If a square has one side that measures 6 inches then perimeter of square is 24 inches.
What is Square?a figure with four equal sides and four right (90°) angles.
We know that in a square all the sides will measure equal length. So the formula for perimeter of square is P=4a or p equal to four times of a.
Where p is the perimeter and a is the measurement of a side.
It is given that measure of one side of square is 6 inches.
So value of a is 6.
Substitue the value of a in the perimeter formula.
Perimeter=4×6
When four is multiplied with six we get twenty four.
=24 inches.
Hence perimeter of the square with one side measure 6 inches is 24 inches.

Sound out the number after the comma next:
You would read that as seven hundred sixty-two.
