what number is divisible by 49 that is divisible by 27?
9514 1404 393
Answer:
1,323
Step-by-step explanation:
The smallest positive number divisible by both 49 and 27 is ...
49×27 = 1,323
__
49 and 27 have no common factors, so the least common multiple is their product.
find the value of each variable using sine and cosine round your answers to the nearest tenth
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.
3 pounds to 24 ounces write each ratio in simplest form
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.

Which critical thinking issue is most relevant to the following situation:
A survey asks the following: Should the President have the line item veto to eliminate waste?
self-interest study
O assumed accuracy from overly precise numbers
voluntary response bias
Ononresponse bias or missing data
perceived lack of anonymity
loaded or leading question
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.

An animal population is modeled by the function A(t) that satisfies the differential equation dA dt equals the product of A divided by 1125 and the quantity 450 minus A . What is the animal population when the population is increasing most rapidly?
45 animals 225 animals 40 animals 180 animals
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]

A standard deviation of 10 values is 8.19. You add 5 points to each score in the sample. The standard deviation for the new sample is:
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
What does standard deviation measure?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]
How to know the standard deviation of the new sample if each score was increased by 5 points?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:
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:
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:
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:
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%!
