Answer: jacob is right
Step-by-step explanation:
each face in a cube is equal, and we know that there are six sides on a cube
this means that we need to find the surface area of one side and multiply it by six to see if jacob is correct
to find the area of one side you would do
a = Lw
a = 10 * 10
a = 100
so one face equals 100 cm^2 so 100 * 6 = 600
600 is less than 1000 so jacob is correct
Answer:
19.7
Step-by-step explanation:
a^2+b^2=c^2
so 18^2+8^2=x^2
324+64=388
x is about 19.7
Answer:
17.11 meters
Step-by-step explanation:
You are using trigonometry in this problem.
The height of the flagpole represents the side <u><em>opposite</em></u> the given angle.
The base of the triangle is given as 19 meters and represents the side <u><em>adjacent</em></u> to the given angle.
Out of the main trigonomentric functions (sine, cosine, and tangent), only tangent uses both the opposite and adjacent sides.
Tan(angle) = opposite / adjacent
If we plug in what we know into that equation: <em>tan(42 degrees) = h / 19</em>
This means that <em>your answer = 19 * tan(42) = 17.11</em> meters
Answer: stratified sampling and judgement sampling
Step-by-step explanation:
Stratified sampling is a probability method that is superior to random sampling because it reduces sampling error. A stratum is a subset of the population that share at least one common characteristic.
While
Judgment sampling is a nonprobability method. The researcher chooses the sample based on judgment. This is usually and extension of convenience sampling. For example, a researcher may decide to draw the entire sample from one "representative" city, even though the population includes all cities. When using this method, the researcher must be confident that the chosen sample is truly representative of the entire population.
Answer:
In math, number blocks are commonly used as models, where a small square equals 1, a long rectangle equals 10, and a large square equals 100. As models, blocks can be used for addition, subtraction, multiplication, and division. You can represent a problem given by using the correct models.
