Answer:
72.5 miles/hour
Step-by-step explanation:
When we say "miles per hour" in English this just is simply the question "If Bailey drove for only one hour, how far did she go?". Now mathematically we can find this very easily by simply dividing 290 by 4, which is equal to 72.5. So Bailey travels 72.5 miles every hour.
If it is confusing about why we do this, think about splitting up 290 miles evenly between 4 hours, how many miles does each hour 'get'. Each would 'get' 72.5 miles. So for every hour Bailey drives she travels 72.5 miles which is the same as saying that she drove at 72.5 miles per hour.

0.7 dividee by 0.35
Answer:
2
Step-by-step explanation:
We can find this because it's asking how many times 0.35 goes into 0.7.
Here's an easier example without decimals:
10 / 2 = 5
This is asking how many times 2 goes into 10. The second number in the equation is asking how many times it can go into the first number. In this case, 2 goes into 10 five times.
So in this case, 0.35 goes into 0.7 2 times. To make it easier, you can also do 70 / 35, which makes it easier without the decimals.
Hope this helps!
Answer: 2
Step-by-step explanation: To divide decimal numbers:

How will the volume of the prism change if each side is increased by a factor of 4?
The volume will be 2 times the original volume.
The volume will be 4 times the original volume.
The volume will be 16 times the original volume.
The volume will be 64 times the original volume.
Answer:
64
Step-by-step explanation:
The volume of a prism is defined by the product of its length (L) times its width (W) times its Height (H): [tex]Volume= L * W * H[/tex]
So, if these dimensions are increased each by a factor of 4, the volume now becomes:
[tex]Volume= 4L *4 W * 4 H = 64 L*W*H[/tex]
That is 64 times the original volume LWH
Answer:

A fish starts at -9 meters and changes -11 meters
Answer:
the growth difference would be -3
Step-by-step explanation:
The final elevation of a fish starts at -9 meters and changes -11 meters is -20 meters.
What is an Integer?Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.
Given that, a fish starts at -9 meters and changes -11 meters.
The fish starts at -9 meter than swims down another 11 meters which results in being -20 meters because it is below sea level.
Therefore, the final elevation of a fish starts at -9 meters and changes -11 meters is -20 meters.

If we convert 22,647 inches into miles, we can get 0.357433710227 miles.
What are miles?The mile, sometimes known as the international mile or the statute mile to differentiate it from other miles, is a British imperial unit and a customary unit of distance in the United States; both are based on the older English unit of length equal to 1,760 yards.
What are yards?Yards are a measurement that is 36 inches long (or wide) in US units.
How to solve this problem?We have to convert 22,647 inches into miles.
Since 36 inches = 1 yard,
1 inch = 1/36 yards
i.e. 22,647 inches = 22,647/36 yards = 629.08333 yards.
Since 1,760 yards = 1 mile,
1 yards = 1/1760 miles
i.e. 629.08333 yards = 629.08333/1760 miles = 0.357433710227 miles
Therefore if we convert 22,647 inches into miles, we can get 0.357433710227 miles.

The combined area of a square and 4 semicircles with each semicircle's diameter equal to the side length (15 cm) of the square is approximately 578.42 cm², hence the closest approximation is 580 cm².
Explanation:To find the closest approximation of the area of a figure that consists of a square and 4 semicircles, where the diameter of each semicircle is equal to the sides of the square (15 cm), we must first calculate the area of the square and then the combined area of the semicircles.
The area of the square (Area_square) is given by the formula:
Area_square = side × side = 15 cm × 15 cm = 225 cm²The area of a full circle with a diameter of 15 cm is:
Area_circle = πr²Since the diameter is 15 cm, the radius (r) is 7.5 cmArea_circle = π(7.5 cm)² ≈ 176.71 cm²The total area of the 4 semicircles is:
Total_semicircles_area = 4 * (0.5 * Area_circle) = 2 * Area_circle ≈ 2 * 176.71 cm² ≈ 353.42 cm²Add the area of the square to the combined area of the 4 semicircles to obtain the total area:
Total_area = Area_square + Total_semicircles_area ≈ 225 cm² + 353.42 cm² ≈ 578.42 cm²Based on this calculation, the closest approximation from the options provided is 580 cm².

5/6 * 1 1/8 * 4/5. First we convert 1 1/8 from a mixed fraction, to give us 9/8, as 8/8 = 1.
5/6 * 9/8 * 4/5. 5 * 9 = 45, and 6 * 8 = 48. 45/48 reduces to 15/16.
15/16 * 4/5. 15 * 4 = 60, and 16 * 5 = 80. 60/80 reduces to 6/8, which reduces to 3/4.

Slope - Intercept form looks like:
y = mx + b, where m is the slope of the line and b is the y-intercept
so, for

a sewage treatment plant has two inlet pipes to its settling pond. one piece can fill the pond 3 times as fast as the other pipe, and together they can fill the pond in 12 hours. how long will it take the faster pipe to fill the pond alone
Answer:
The faster pipe will take 16 hours to fill the pond alone
Step-by-step explanation:
* Lets explain how to solve the problem
- A sewage treatment plant has two inlet pipes to its settling pond
- One pipe can fill the pond 3 times as fast as the other pipe
∴ The rate of the faster pipe is 3 times the rate of the second pipe
- The rate and the time are inverse proportion because;
time = job/rate and the job here is constant (fill pool), then
time × rate = constant
∵ The rate of the faster pipe is 3 times the rate of the second pipe
∴ The time of the second pipe is 3 times the time of the faster pipe
- Assume that the time of the faster pipe is t
∵ The time of the faster pipe is t
∴ The time of the second pipe is 3t
- Together they can fill the pond in 12 hours
∴ [tex]\frac{1}{3t}+\frac{1}{t}=\frac{1}{12}[/tex]
- The L.C.M of 3t and t is 3t
∴ [tex]\frac{1}{3t}+\frac{3}{3t}=\frac{1}{12}[/tex]
∴ [tex]\frac{1+3}{3t}=\frac{1}{12}[/tex]
∴ [tex]\frac{4}{3t}=\frac{1}{12}[/tex]
- By using cross multiplication
∴ 48 = 3t
- Divide both sides by 3
∴ t = 16
∵ t represents the time of the faster pipe
∴ The time of the first pipe is 16 hours
* The faster pipe will take 16 hours to fill the pond alone
Final answer:
The faster pipe will take 6 hours to fill the sewage treatment pond by itself, calculated by setting up and solving a rate problem based on the information provided.
Explanation:
To determine how long it will take for the faster pipe to fill the sewage treatment pond alone, we can set up a rate problem where the pipes are filling the pond at their rates and a combined rate.
Let's define the rate of the slower pipe as 1/x ponds per hour (where x is the number of hours it takes the slower pipe alone to fill the pond). This means that the faster pipe works at a rate of 3/x (since it's three times as fast).
Combined, their rate is 1/12 ponds per hour (because together they fill the pond in 12 hours). Our equation will now look like this: 1/x + 3/x = 1/12.
Solving this equation, we find that x, the time it takes for the slower pipe to fill the pond alone, is 18 hours. Therefore, the faster pipe, being three times as fast, will take 18 hours divided by 3, which equals 6 hours to fill the pond alone.

Answer: 3rd option
Step-by-step explanation: The answer would be the third option. Let's go through each one and explain why it's correct or incorrect. First of all, our function is y = x - 3 so we can plug numbers into our X and Y. If we follow the function y = x - 3, we have 8 = 10 - 3 which is incorrect for the first one so that can't be it. For the nest one, we have 13 = 10 - 3 which also does not make sense. For the third one, we have 7 = 10 - 3 which is correct. And the last one, we have 3 = 10 - 2 which is wrong. Therefore, the third option is the answer.
Martha spent $2.90 on 3 1\2 pounds of bananas. How much did she spend on each pound of bananas
I think th answer is $0.82.
Hope this helps
Answer:
$ 0.83 on one pound
Step-by-step explanation:
Given: Martha spent $2.90 on 3 1\2 pounds of bananas.
To Find: How much did she spend on each pound of bananas
Solution:
Amount spent by martha on bananas = [tex]\$[/tex] [tex]2.90[/tex]
Quantity of bananas bought = [tex]3\frac{1}{2}[/tex] [tex]\text{pound}[/tex]
= [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex]
Now,
Martha spent [tex]\$[/tex] [tex]2.90[/tex] on = [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex] of bananas
therefore,
Amount spent by Martha on one pound of banana= [tex]\frac{\text{quantity of banana bought}}{\text{Amount spent on bananas}}[/tex]
= [tex]\frac{2.90}{\frac{7}{2}}[/tex]
= [tex]\frac{2.90\times2}{7}[/tex]
= [tex]\$[/tex] [tex]0.83[/tex]
Hence amount spent by martha on one pound of banana is [tex]\$[/tex] [tex]0.83[/tex]
