A typical dove weighs 345g. A typical duck weighs 1.2kg. What is the difference, in grams, of the weights of a duck and a dove?
Answers
Answer:
855 grams
Step-by-step explanation:
First convert the 1.2kg into grams.
1.2kg=1200 grams.
Now we have equal units of measurement. We then subtract: 1200g-345g=855g

Water makes up about 71% of the Earth’s surface, while the other 29% consists of continents and islands. 96% of all the Earth’s water is contained within the oceans as salt water, while the remaining 4% is fresh water located in lakes, rivers, glaciers, and the polar ice caps.
The total volume of water on Earth is 1,386 million cubic kilometers.
a. What is the volume of salt water.
b. What is the volume of fresh water.
Answers
Answer:
a. what is the volume of salt water.
explanation:
So 71 percent of the earth's surface is water and that water is broken down as salt, water and fresh water, so 96 percent of 71 percent is salt.

Find the surface area of the prism. Write your answer as a decimal.
A triangular prism. The base triangle is a right triangle with base of 10 inches, height of 9 inches, and hypotenuse of 13.5 inches. The height of the prism is 9 inches.
Answers
Answer:
5
Step-by-step explanation:
9×9 - 13.5 ÷10=9 =*÷&#>÷<$<÷>#*#*#*#*#*=*/&=
The area of the triangular base is:
Area = (1/2) * base * height = (1/2) * 10 in * 9 in = 45 in^2
The area of the three rectangular faces is:
Area = length * width
For the rectangular face adjacent to the base triangle, the length is the hypotenuse of the base triangle, which is 13.5 inches, and the width is the height of the prism, which is 9 inches. Therefore, the area is:
Area = 13.5 in * 9 in = 121.5 in^2
For the other two rectangular faces, the length is the hypotenuse of a right triangle with legs of 9 inches and 10 inches, which can be found using the Pythagorean theorem:
c^2 = a^2 + b^2
c^2 = 9^2 + 10^2
c = sqrt(81 + 100) = sqrt(181) ≈ 13.45 in
The width is still 9 inches, so the area of each face is:
Area = 13.45 in * 9 in ≈ 121.05 in^2
Therefore, the total surface area of the prism is:
Surface Area = 2 * Area of Base + 3 * Area of Rectangular Face
Surface Area = 2 * 45 in^2 + 3 * 121.05 in^2 ≈ 549.15 in^2
Rounding to two decimal places, the surface area of the prism is approximately 549.15 in^2.

Lola finished her swimming lesson at 2:15 p.m. and read a book at 2:50 p.m.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
Lola's swimming class began at 1:30 p.m. and lasted 45 minutes.
She then spent 35 minutes reading a book.
To determine the time did she finish her swimming lesson and the time did she finish reading.
swimming end time = began time + class duration
swimming end time = 1:30 p.m. + 45 minutes
swimming end time = 2:15 p.m.
reading end time = began time + reading duration
reading end time = 2:15 p.m. + 35 minutes
reading end time = 2:50 p.m.
Thus, she finished her swimming lesson at 2:15 p.m. and read a book at 2:50 p.m.

Answer:
First one is 7.1415926,
Second one is \(84 inch^{2}\)
Step-by-step explanation:
First for the square plus the two half circles: The two half circles are semi-circles, so two semi-circles put together equals a full circle.
Equation for the circle:
\(\pi (2/2)^{2} \\=\pi (1)^{2}\)
=\(\pi\)
≅3.1415926 \(inch^{2}\) (This is too long for me to write down, actually no body can write it down , since it's an infinity unrepeating decimal)
Then the square's area is:
\(2^{2} \\=4\)
Lastly 4+3.1415926
=7.1415926
Second one I am going to draw in the file first, then I'll write how I solved it here!
OK, so:
\((5)(10)+(7)(4)+(15-(5+7))(4)/2)\\=50+28+(12/2)\\=78+6\\=84 inch^{2}\)

Hope it helped!
Answer: C
Step-by-step explanation:
Well Well, so from Lesson 4 to 6 The $ added is 55 then from lesson 6 to 9 the $ added is 82.50. So you subtract 82.50-55=$27.50 which is the cost per lesson. Then to find out the initial fee you do 4*27.50=110 which means that you subtract 145-110=$35 and you get the initial fee. What you do to get the the initial fee is you go back to 0 lessons that's why I multiplied 4*27.50 and subtract that from the cost 145 and u get the initial fee! Hope this helped you comprehend what they're asking you!

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

The cost to rent a boat can be modeled by the equation C = 18h + 35 where C is the total cost in dollars and h is the number of hours in which the boat is rented.
What is the rate of change?
Answers
Answer:
18
Step-by-step explanation:
Slope, rate of change, unit rate, speed are synonyms
y = mx + b
Slope "m" is a rate of change.
~~~~~~~~~~
C = 18h + 35
m = 18
The rate of change from the given equation is 18 dollars per hour
Given :
The cost to rent a boat can be modeled by the equation C = 18h + 35
Where h is the number of hours and 'C' is the total cost
Rate of change represents the cost to rent a boat for one hour .
From the given equation , \(C=18h+35\)
35 is the initial cost and 18 is the cost to rent a boat every hour
The rate of change is cost to rent a boat for one hour that is our slope.
Slope is 18
The rate of change is 18 dollars per hour

Ix+1/2I=3 ( is is the absolute value symbols)
Answers
Answer:
x= 2.5 and -3.5
Step-by-step explanation:
To solve the equation Ix+1/2I=3, we can break it down into two cases: one where x+1/2 is positive, and one where x+1/2 is negative.
Case 1: x+1/2 is positive
In this case, the absolute value of x+1/2 is equal to x+1/2 itself. So we can rewrite the equation as x+1/2=3. To solve for x, we subtract 1/2 from both sides: x=3-1/2. Simplifying further, we have x=2.5.
Case 2: x+1/2 is negative
In this case, the absolute value of x+1/2 is equal to -(x+1/2). So we can rewrite the equation as -(x+1/2)=3. To solve for x, we first distribute the negative sign: -x-1/2=3. Then, we add 1/2 to both sides: -x=3+1/2. Simplifying further, we have -x=3.5. To isolate x, we multiply both sides by -1: x=-3.5.
So, the solution to the equation Ix+1/2I=3 is x=2.5 and x=-3.5.
