Sanjay went blueberry picking along a 3-mile walking path. He picked blueberries steadily along the walk. When he was finished, he had collected 50 ounces of blueberries.
How many ounces of blueberries did Sanjay pick each mile?
Write your answer as a proper fraction or mixed number.
Answer:
16 2/3 per a mile
Step-by-step explanation:
50 ounces of blueberries/3 miles = 16.666 repeated
16.666 repeated = 16 2/3 ounces/mile
Answer: Sanjay picked 16.66 ounces each mile
Step-by-step explanation:
For this exercise let "x" represents the amount of ounces of blueberries that Sanjay picked each mile, along the 3-mile walking path.
According to the information given in the exercise, you know that Sanjay picked a total amount of 50 ounces of blueberries along the walking path.
Then, knowing that the length of that walking path is 3 miles, you can set up the following proportion:
\(\frac{3}{50} = \frac{1}{x}\)
Now, the next step is to solve for "x" in order to find its value.
You get that this is:
\((x)(\frac{3}{50} )=1\\\\x=(1)(\frac{3}{50} )\\\\x=16.66\)
Therefore, knowing the value of "x", you can conclude that Sanjay picked 16.66 ounces of blueberries each mile.
16.66 = 16 2/3

Step-by-step explanation:
A composite figure is shown.
A five-sided figure with two parallel sides. The shorter one is 16 feet. The height of the figure is 22 feet. The portion from the vertex to the perpendicular height is 6 feet. The portion from a point to a vertical line created by two vertices is 6 feet.
Which of the following represents the total area of the figure?
968 ft2
616 ft2
484 ft2
352 ft2
Option (C) 484 ft²
Step-by-step explanation:The Five Sided figure can be divided into 2 Triangles and 1 Rectangle.
The Dimensions of the Triangle that is on the Left are as follows:Length of the triangle = 22 Feet
Breadth of the triangle = 8 Feet
Area of the triangle = (Length * Breadth) / 2
= (22 * 8) / 2
= 176/2
= 88 ft²
The Dimensions of the Triangle that is on the Right are as follows:Length of the triangle = 22 Feet
Breadth of the triangle = 4 Feet
Area of the triangle = (Length * Breadth) / 2
= (22 * 4) / 2
= 88/2
= 44 ft²
The Dimensions of the Rectangle are as follows:Length of the rectangle = 22 Feet
Breadth of the rectangle = 16 Feet
Area of the triangle = (Length * Breadth)
= (22 * 16)
= 352 ft²
The Total Area of the Five Sided figure can be found by summing up the areas of the Triangles and the Rectangle.
The Total Area of the figure is 88 + 44 + 352 = 484 ft²
So, the total area of the figure is 484 ft².

The area of the trapezoid is 308 ft2, the correct option is D.
We are given that;
Shorter side= 16 feet
b2=6+6=12 ft
Height= 22 feet
Now,
To find the area of a trapezoid, you need to know the lengths of the two parallel sides (the bases) and the height. The formula for the area of a trapezoid is:
A=21(b1+b2)h
where b1 and b2 are the lengths of the bases and h is the height1.
Substitute these values into the formula and simplify:
A=21(16+12)×22
A=21×28×22
A=14×22
A=352
Therefore, by the area the answer will be 308 ft2.

According to the information the expression that represents the average change in temperature each minute is -1.1°F/minute, and the average change in temperature each minute in the second experiment is -0.1°F/minute.
How to find the average change in temperature (first experiment)?a. To find the average change in temperature each minute, we need to calculate the total change in temperature over the 10 minutes and divide by the total number of minutes. We can represent the changes in temperature using the following values:
-2, -2, -2, -2, -3, -3, -3, 0, 0, 6
The total change in temperature is:
-2 -2 -2 -2 -3 -3 -3 + 0 + 0 + 6 = -11°F
The total number of minutes is 10, so the average change in temperature each minute is:
(-11°F) / (10 minutes) = -1.1°F/minute
Therefore, the expression that represents the average change in temperature each minute is -1.1°F/minute.
How to find the average change in temperature (second experiment)?b. Let's denote the average change in temperature each minute in the first experiment as x. Then the average change in temperature each minute in the second experiment is x+1°F/minute.
Using the same data as in part a, the total change in temperature in the second experiment would be:
(-2 -2 -2 -2 -3 -3 -3 + 0 + 0 + 6) * 1°F/minute = -11°F/minute
The total number of minutes is still 10, so the average change in temperature each minute in the second experiment is:
(-11°F/minute) / (10 minutes) = -1.1°F/minute
But this value is for the first experiment, so we need to add 1°F/minute to get the average change in temperature each minute in the second experiment:
-1.1°F/minute + 1°F/minute = -0.1°F/minute
Therefore, the average change in temperature each minute in the second experiment is -0.1°F/minute.

(conversion factors and equivalent rates homework by the way)
Answer: conversion factor is just how much of it is in another unit
Step-by-step explanation:
for example, 5280 feet are in a mile so the original rate of 15 in a hour can be turned into the equation on the first image.
Original rate (15 miles) x conversion factor (5280 feet are in a mile)
So when you multiple get 79,200 which simple means, in one hour she will go 79,200 ft. This concept can be applied to other scenarios such as feet and meter, liters and gallons, miles and kilometers, all that’s necessary is to know the conversion rate. The conversion factor is simple how much of your term is in another, this may be confusing but imagine it like this how many feet are in a yard? The answer is 3 so the conversion factor is just 3ft:1yd
Add the negatives.
+4 - 3 - 4 + 2 - 1
I just dont get it
Answer: -2
Step-by-step explanation:
since there are no multiplication you can simply go from left to right doing simple math. You start from a +4 that would be a positive 4, you subtract -3 so you get +1 then you subtract -4 and the result is -3 (negative 3) so now you are currently working with numbers lower than 0, adding +2 will make it -1 and finally you subtract for -1 and that will make it -2.

Step-by-step explanation:
The round-trip distance between City A and City B is 150 miles. City C and City D are between City A and City B. You make the round trip in 3 days. On the first day, you leave City A and travel 46.8 miles and stay in City C. On the second day, you travel 51.4 miles and stay in City D. Find the distance between City B and City D.
Answer: 51.8 Miles from D and B
Step-by-step explanation:
A - C = 46.8 ~ Day 1
C - D = 51.4 ~ Day 2
- Represents Total Trip -
A - 46.8 - C - 51.4 - D - ? - B
150 - 46.8 = 103.2
103.2 - 51.4 = 51.8
If you total
46.8+51.4+51.8 = 150 (Total Distance)
So, the distance between D and B is 51.8

D. 55,000
Answer:
1900
Step-by-step explanation:
hello bro how r u i think answer is 1835 but there is no option
The required mass of the proton is 1900 times the mass of the electron. Option B is correct.
What is proportionality?Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
here,
The mass of an electron is approximately e = 9.1 x 10⁻³¹ kilograms.
The mass of a proton is approximately p = 1.7 x 10⁻²⁷ kilograms.
Now
p/e = 1.7 x 10⁻²⁷/9.1 x 10⁻³¹
p/e ≈ 1900
p = 1900e
Thus, the required mass of the proton is 1900 times the mass of the electron.

Step-by-step explanation:
(<= means "is less than or equal to")
If we do reverse math, we can subtract 1 from both sides, leaving us with 4x <=-12. After that, we can divide both sides by 4, leaving us with X<=-3. This also falls within the parameters of 3x<=0, so no further solving is required.
