Answer:
89 m is the answer gl!
:)))
Answer:
Area 5 x 8 = 40cm^2
If 5cm is a perpendicular height then of course its 40cm
But if its slant height then we can do the following by flipping the triangles diagonal to find the longer length that sits perpendicular with the perpendicular line.
47.2cm^2 if using full decimal in diagonal finding
and if rounding diagonal fining to 9.4cm we x by 5 we get 9.4 x 5 = 47cm^2
Step-by-step explanation:
Parallelogram no height
Step 1 we use Pythagoras to get the diagonal measure so we can flip the triangle measure and re calculate .
sqrt of 25+ sqrt 64 = sq rt 89 = 9.43
9.43cm is your hypotenuse diagonal
and then deduct 9.43 - 8 = 1.43cm x 5 use that length and area to deduct from 8x 5 = 40
1/2 x 9.43 x 5 = 23.575
1/2 x 1.43 x 5 = 3.575
23.575 - 3.575 = 20
20+20 = 40cm
If this is shown its proven the slant has been added and taken away.
To represent the method if just slant was given and no height.

Answer: 2,048 in³
Step-by-step explanation:
Step 1: Find the radius
r=8
*Radius: 1/2 a circle*
Step 1: Plug the numbers into the formula
V= 4/3πr to the power 3
Even though pi is an irrational number, the question says to use 3 in its place.
V= 4/3(3)(8 to the power 3)
Step 3: Solve the equation
Method #1: Break it down using PEMDAS to solve manually
According to PEMDAS, exponents come first.
8³= 8x8x8= 512
Now, multiplication comes next, from left to right.
the first multiplication is 4/3x3= 4.
Finally, we have 4x512= 2,048 in³ (inches cubed).
That is the volume.
Method #2: Use a calculator

Step-by-step explanation:
The associative property is ax(bxc)=(axb)xc
So the first option is merely moving the parentheses around. This is associative.
The second option is distributive. Do not pick this option.
The 3rd option is also moving parentheses around. This is associative.

janine wants to build a model using 1/2 inch cube how many 1/2 inch cube would she use to build a solid, cube-shaped model with side lengths of 4 inches? show your work
Answers
Answer:
512 1/2 inch cubes
Step-by-step explanation:
-In order to get 4 inches width, you will need 8 1/2 cubes (1/2 x 8 = 4)
-In order to get 4 inches height, you will need 8 1/2 cubes (1/2 x 8 = 4)
-In order to get 4 inches length, you will need 8 1/2 cubes (1/2 x 8 = 4)
8 length x 8 width x 8 height = 512 1/2 inch cubes to build a solid 4x4x4 inch cube.
Answer:
512 1/2 cubes
Step-by-step explanation:
The volume of the cube model : 4 x 4 x 4 = 64 cubic inches
1/2 x 1/2 x 1/2 = 1/8 - one 1/2 inch cube
64 / 1/8 = 512 1/2 inch cubes

Rosalinda is 45 years old. How old is Erik if the
mean age of the four friends is 33.5?
Answers
Answer:
28 years
Step-by-step explanation:
Sum of the years of Lance , Ted, Rosalinda = 39 + 22 +45 = 106 year
Sum of the years of Lance , Ted, Rosalinda & Erik = 33.5*4 = 134.0 year
Age of Erik = 134 - 106 = 28 years

You exercise for 34 of an hour. You jump rope for 13 of that time. In simplest form, what fraction of the hour do you spend jumping rope?
Answers

You spend 1/4 of the hour jumping rope. The question states that 1/3 of 3/4 of an hour is spent jumping rope.
Step-by-step explanation:
Answer: You spend 1/4 of the hour jumping rope.
Step-by-step explanation:
The question states that 1/3 of 3/4 of an hour is spend jumping rope
To find this, multiply 3/4 by 1/3
3/4 times 1/3 = 3/12 = 1/4
So one third of 3/4 is 1/4
A certain star is 4.6 x 10^2 light years from the Earth. One light year is about 5.9 x 10^12 miles. How far from the earth (in miles) is the star? Has to be answered in scientific notation
Answers
Answer:
2.537 x 10¹⁵ miles
Step-by-step explanation:
We are given the following:
1 light year = 5.9 x 10¹² miles
Distance of the star = 4.3 x 10² light years
To get this we just convert the distance of the star in light years into miles.
We cancel out the light years and then we are left with:
In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.
Coefficients:
4.3 x 5.9 = 25.37
Exponents of 10:
10² x 10¹² = 10⁽²⁺¹²⁾=10¹⁴
Then we combine them again to form a scientific notation:
25.37 x 10¹⁴
But since the standard in writing a scientific notation, the coefficient needs to be a number from 1-9, we need to move the decimal. When we move the decimal to the right or left, we change the exponent of the power of 10. Since we will move it once to the left, we add 1.
The answer will then be:
2.537 x 10¹⁵ miles

1. Is the average change in population the same now as it was 50 years ago? Explain your answer.
2. Reflect on the interpretation of your data.
3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.
Answers
1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.
2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.
3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.
