Answer:
1
Step-by-step explanation:
(2^3 x 2^-1) / 2^2
First, solve what's in the parentheses remembering that when two exponents have the same base and are being multiplied together, their exponents add together:
3 + (-1) = 2
(2^2) / 2^2
And when two exponents with the same base are being divided by each other, the exponents subtract:
2 - 2 = 0
(2^0)
And any number to the power of 0 equals 1:
(2^0) = 1

Holland added three decimals that made a sum of 2. One of the decimals was 0.34.
What are two other decimals Holland could have used to make a sum of 2? Explain how you know.
The two other numbers could be 0.83.
First, do the equation 2 - 0.34 = 1.66.
Next, divide 1.66 ÷ 2 = 0.83.
Finally, add 0.83 + 0.83 + 0.34 = 2.
So the two other decimals Holland could do is 0.83.

Martin Luther King Jr was 5 feet tall, 7 inches (67 inches) tall. The statue is 30 feet tall. What is the ratio of Martin Luther King Jr's actual height to the statue?
Answer:
67 inches : 360 inches
Step-by-step explanation:
30 feet = 360 inches
Martin Luther King Jr : Statue
67 : 360
The ratio of Martin Luther King Jr's actual height to the statue is 67 : 360.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
Martin Luther King Jr height = 5 feet tall and 7 inches
This is 67 inches tall.
The statue height = 30 feet tall.
This is 12 x 30 = 360 inches
Now,
The ratio of Martin Luther King Jr's actual height to the statue.
= 67 : 360
Thus,
The ratio is 67 : 360.

Determine whether the measures for the figure shown proportional.
A. the length of a side and the perimeter
B. the length of a side and the area
Answer: 5 length & width
Step-by-step explanation:
Since this is a square all sides would be the same length & width which would be 5 because each side is symmetric. So if you do 5 times as many sides as there is (5 x 4) it would give you 20
So the LENGTH of EACH side is 5 and the AREA in total or PREMIETER would be 20 all together.

Which of the following points best represents the location of -1 5/8 on the number line?
Answer:
A
Step-by-step explanation:
Looking at the number line, you will notice that A, B, and C are less than 0.
Eliminate D, which is greater than 0.
Further still, as negative numbers get 'smaller', they go from -1 to -∞.
i.e.: -1 > -2 > -3
if you forget the above fact, looking at the number line, you can see that A is between -1 and -2, and [tex]-1\frac{5}{8}[/tex] is between -1 and -2 just as [tex]1\frac{5}{8}[/tex] is between 1 and 2.
Then, simply counting the ticks from -1 to -2, you can see that A falls on the 5th tick, while -2 falls on the 8th tick from -1.
Hope this helped.

It is away from the hive for a total of 19 minutes. A. what equation can you use to find the distance of the flowerbed from the hive? B. How far is the flowerbed from the hive? Let d be the distance of the flowerbed from the hive.
Answer:
5 minutes
Step-by-step explanation:
d / r = t
The bee is flying for 19 - 14 minutes
(d / 6) + d / 4) = 5
Answer: 25 feet
Step-by-step explanation:
19 - 14 = 5
total travel time = 5 min
av. between 6 and 4
= 6+4÷2 = 5

Answer: Not what's written down.
Step-by-step explanation:
Okay, so basically, if you have a letter, no other number can go with that number with a letter. So like 5x + 2b -7.
There is only one number that has x, so 5x.
Same with b. 5x + 2b.
Now, there is no letter with the 7, so that will stay the same.
So, the answer is 5x + 2b -7.

Write an equation with a slope: -3/4 and y-intercept: -1/4
Answer:
y = (-3/4)x - 1/4
Step-by-step explanation:
Use the slope-intercept formula y = mx + b. Here m = -3/4 and b = -1/4, and so: y = (-3/4)x - 1/4
The equation of the line with slope -3/4 and y-intercept is -1/4 is y=-3/4x-1/4.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of the line is the ratio of the rise to the run, or rise divided by the run.
It describes the steepness of line in the coordinate plane.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Given that the slope is -3/4 and y-intercept is -1/4.
We have to find the equation of line with slope -3/4 and y-intercept is -1/4.
m=-3/4 and b = -1/4
Now plug in these values in slope intercept form y=mx+b
y=-3/4x-1/4
Hence, y=-3/4x-1/4 is the equation of the line with slope -3/4 and y-intercept is -1/4.

Let's write a rule for the relationship between the number of non-fiction books (n) and the number of fiction books (f) based on the given information.
We are told that the library loans 4 times as many non-fiction books as it does fiction books.
This means that the number of non-fiction books (n) is equal to 4 times the number of fiction books (f).
Mathematically, we can express this relationship as:
n = 4f
Where:
n = Number of non-fiction books
f = Number of fiction books
Thus,
The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

Answer: 20c + 10.
Step-by-step explanation:
(c represents crates)
I wrote each equation separately first.
Supplier A: 4c + 6
Supplier B: 6c - 1
Supplier C: 10c + 5
We can add all the cs from each supplier giving us 4c + 6c + 10c which equals 20c. Now we can add the extra shoes as, 6 + (-1) + 5 equaling 10. I wrote -1 because we are missing that shoe, but you can write it as 6 - 1 + 5 instead. Together the two numbers make the equation 20c + 10. Hope that helps : )

—————————————————
(6 − 3) × 4 − 7
Answer:
42 - 12 ÷ 6 = 40
(6 - 3) x 4 - 7 = 5
Step-by-step explanation:
First of all, when coming over to an equation with a division or multiplication sign, we first solve the division or multiplication first, then the subtraction or addition. So, 12 ÷ 6 = 2. Then, 42 - 2 = 40. And in the other one we must first solve what's in the parenthesis. So, 6 - 3 = 3. Then, we multiply, 3 x 4 = 12. Then subtract. 12 - 7 = 5.
