What is the total area, in square feet, of the figure? (If possible please explain how you got your answer)

9514 1404 393

Answer:

  a = 14.9

  b = 11.1

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relationships.

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

In this triangle, that means ...

  sin(48°) = b/a

  cos(48°) = 10/a

Using the cosine relation, we can find 'a':

  a = 10/cos(48°) ≈ 14.9

Then using the sine relation, we have ...

  b = a·sin(48°) ≈ 11.1

_____

Additional comment

When computing 'b', the full precision value of 'a' should be used.

Step-by-step explanation:

Answer:

4 Blue chips

6 Yellow chips

10 Red chips

Imagine 20% as 2 of 10. We have 20 chips, and that's double of that. So if we have 2/10... we will have 4/20

Same with the yellow chips. Imagine 30% as 3 of 10, again double that... 6/20.

It doesn't directly say the percent of design a computer representation but we can infer that if we have 20% and 30%... that makes 50%, there is only 100 in a percent, so that means there is 50% left! We repeat the process where we envision 50% as 5 of 10, double that. Now we have 10 of 20, 50%!

Answer:

£212.5

Step-by-step explanation:

15% of 250 = 37.5

250 - 37.5 = 212.5

Answer:

8

Step-by-step explanation:

so openeing the parenthesis we get

Answer:

5.5

Step-by-step explanation:

57-29.5 / 10-5 = 5.5

Answer:

5.5

Step-by-step explanation:

The rate of change of a relationship is the ratio of corresponding changes in value. Symbolically, we indicate a change with the greek letter Δ (pronounced "delta"). A change in x is written Δx ("delta eks") and a change in y is written Δy ("delta why"). We're looking for the ratio Δy/Δx ("delta y over delta eks").

Mathematically, Δx and Δy are the differences between two corresponding x an y values. To pick these, we can take any two rows in our table. Let's pick rows 4 and 2, nice whole numbers:

[tex]\Delta{x}=20-10=10\\\Delta{y}=112-57=55\\\Delta{y}/\Delta{x}=55/10=11/2=5.5[/tex]

We can confirm that this holds for every other pair, too - picking rows 2 and 1 as an example:

[tex]\Delta{x}=10-5=5\\\Delta{y}=57-29.5=27.5\\\Delta{y}/\Delta{x}=27.5/5=275/50=11/2=5.5[/tex]

Answer:

B. -3d + 47.25

Step-by-step explanation:

Each of them has $15.75

Each spent $d

Amount each still has = 15.75 - d

Therefore, total amount the 3 of them has = 3(15.75 - d) = 3*15.75 - 3*d

= 47.25 - 3d

Which is also am equivalent of -3d + 47.25

Answer:

8.19

Step-by-step explanation:

Adding 5 points to each score in the sample has no effect on the standard deviation. The standard deviation remains the same and constant.

Therefore, the standard deviation for the new sample is 8.19

You can use the fact that standard deviation is a measure of variation.

The standard deviation of the new sample will be same as the old standard deviation, which is 8.19

Standard deviation measures how much the data points vary or disperse from the mean of the data.

The standard deviation is calculated as:

[tex]\sigma = \sqrt{\dfrac{\sum (\overline{x} - x_i)}{n}[/tex]

Since each score was increased by 5 points, we have the mean increased by  5 point too

[tex]\overline{x} = \dfrac{1}{n}\sum(x_i) \\\\x_i -> x_i + 5\\\\\overline{x} = \dfrac{1}{n}\sum(x_i + 5) = \dfrac{5n}{n} + \dfrac{1}{n}\sum(x_i) = 5 + \dfrac{1}{n}\sum(x_i)[/tex]

Putting new mean and new values in the standard deviation formula, we get:

[tex]\sigma = \sqrt{\dfrac{\sum (\overline{x} + 5 - x_i - 5)^2}{n}} = \sqrt{\dfrac{\sum (\overline{x} - x_i)}{n}\\[/tex]

Thus, standard deviation won't change and will stay same as before.

Thus,

The standard deviation of the new sample will be same as the old standard deviation, which is 8.19

Answer:

a) [tex]\log_{9} 8 + \log_{9} 11 = \log_{9} 88[/tex]

b) [tex]\log_{7} 11 - \log_{7} 3 = \log_{7} \frac{11}{3}[/tex]

c) [tex]\log_{7}\frac{1}{81} = -4\cdot \log_{7} 3[/tex]

Step-by-step explanation:

Now we proceed to solve each case by appropriate rules for logarithms.

a) The following property shall be used: [tex]\log_{c} a +\log_{c} b = \log_{c} a\cdot b[/tex] ([tex]a = 8[/tex], [tex]b = 11[/tex], [tex]c = 9[/tex])

[tex]\log_{9} 8 + \log_{9} 11 = \log_{9} 8\cdot 11[/tex]

[tex]\log_{9} 8 + \log_{9} 11 = \log_{9} 88[/tex]

b) The following property shall be used: [tex]\log_{c} a - \log_{c} b = \log_{c} \frac{a}{b}[/tex] ([tex]a = 11[/tex], [tex]b = 3[/tex], [tex]c = 7[/tex])

[tex]\log_{7} 11 - \log_{7} 3 = \log_{7} \frac{11}{3}[/tex]

c) The following properties shall be used: [tex]\frac{1}{d} = d^{-1}[/tex], [tex]\log_{c} a^{b}[/tex]

[tex]\log_{7} \frac{1}{81} = \log_{7} 81^{-1}[/tex]

[tex]-\log_{7} 81[/tex]

[tex]-\log_{7} 3^{4}[/tex]

[tex]\log_{7}\frac{1}{81} = -4\cdot \log_{7} 3[/tex]

Answer:

225 animals

Step-by-step explanation:

From the given information:

[tex]\dfrac{dA}{dt} = ( \dfrac{A}{1125}) (450 - A)[/tex]

[tex]\dfrac{dA}{dt} = \dfrac{450A - A^2}{1125}[/tex]

For a population increasing most rapidly; we have:

[tex](\dfrac{dA}{dt} \implies max = A')[/tex]

Thus; for [tex]\dfrac{d}{dA} ( \dfrac{dA}{dt}) \implies \dfrac{450-2A}{1125}[/tex]

[tex]\dfrac{dA'}{dA} \implies 0 \\ \\ \\ A = 225[/tex]

Answer: loaded or leading question

Step-by-step explanation:

Loaded or leading questions aim to elicit a particular response from the respondents by including an assumption that makes people feel bad or good if they answer in a certain way. It essentially plays on their emotions and ideals.

The question in the survey is a loaded question because in saying/assuming that the veto will be able to eliminate waste, it makes people more likely to vote in the affirmative as they would want the president to either get rid of waste or would feel bad if they did vote for such an environmental endeavour.

Answer:

2:1

Step-by-step explanation:

First we convert 3 pounds into ounces which is 3x16 because 1 pound=16 ounces. So 48 ounces=3 pounds. So know we have the ratio 48:24 which we can simplify to 2:1

Hope this helps :)

The required simplest ratio for 3 pounds to 24 ounces is 1 : 8.

Given that,
3 pounds to 24 ounces write each ratio in simplest form is to be determined.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Here,
The ratio of 3 pounds to 24 ounces,
Simplest form = 3 / 24 = 1 / 8.

Thus, the required simplest ratio for 3 pounds to 24 ounces is 1 : 8.
