Answer:
Now, the formulas for other trigonometry ratios are: Cot θ = 1/tan θ = Adjacent side/ Side opposite = AB/BC. Sec θ = 1/Cos θ = Hypotenuse / Adjacent side = AC / AB. Cosec θ = 1/Sin θ = Hypotenuse / Side opposite = AC /BC
The population density of City A is 6000 people per square mile. City B is a dilation of City A with scale factor 1.5 . If City B has 3/5 of the population of City A, what is the population density of City B?
Answer:
[tex]1600\ \text{people per square mile}[/tex]
Step-by-step explanation:
Number of people per square mile in City A is 6000.
In terms of size City B is a dilation of City A with scale factor 1.5.
This means a length of 1 mile in city A would be 1.5 miles in city B.
So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]
City B has [tex]\dfrac{3}{5}[/tex] of the population of City A.
So the population density of City B would be
[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]
The population density of City B is [tex]1600\ \text{people per square mile}[/tex].

Identify the pair of congruent corresponding angles and the corresponding sides.
What is the equation of the line that passes through the point (-1, 4) and has a
slope of -5?
Answer:
Step-by-step explanation:
y - 4 = -5(x + 1)
y - 4 = -5x - 5
y = -5x - 1
ASAP! what type of angles are <3 and <10
A. Consecutive interior angles
B. Alternate exterior angles
C. alternative interior angles
D. Corresponding angles
Answer:
∠3 and ∠10 are;
B. Alternate exterior angles
Step-by-step explanation:
From the given diagram, we have;
∠3 and ∠10 are angles on the same transversal
The location of ∠3 and ∠10 are on the outer (exterior) part of the two lines crossed by the transversal that forms ∠3 and ∠10 such that the two lines comes between the angles
∠3 and ∠10 are on the alternate sides of the transversal such that ∠3 is below the transversal and ∠10 is above the transversal
Therefore, ∠3 and ∠10 are alternate exterior angles.
Diego and Jada are both trying to write an expression with fewer terms that is equivalent to
7a + 5b - 3a + 4b
Jada thinks 10a - 1b is equivalent Diego thinks 4a + 9b is equivalent
Answer: Diego, 4a + 9b is equivalent
Step-by-step explanation:
7a + 5b - 3a + 4b
= (7a - 3a) + (5b + 4b) We rerange the variables, and put them together with (), which make it more clear to solve.
= 4a + 9b

Answer: 6
Step-by-step explanation:
0.8) 498 what is the answer
Step 1: We make the assumption that 498 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=498$100%=498.
Step 4: In the same vein, $x\%=4$x%=4.
Step 5: This gives us a pair of simple equations:
$100\%=498(1)$100%=498(1).
$x\%=4(2)$x%=4(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{498}{4}$
100%
x%=
498
4
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{4}{498}$
x%
100%=
4
498
$\Rightarrow x=0.8\%$⇒x=0.8%
Therefore, $4$4 is $0.8\%$0.8% of $498$498.

A rectangle prisms base is 8 feet long. It is 2 1/2 times taller than it is long and 1/2 wide as it is tall. What is the volume of the rectangular prism?
Answer:
1600 cubic feet
Step-by-step explanation:
8 x 2 1/2 = 8 x 2.5 = 20
20 divided by 1/2 = 10
8 x 10 x 20 = 1600

While running a 2-sample z-test for two proportions, you find a test statistic of z=1.946. If the test is two-tailed and α=0.05, what decision will you make?
Answer:
Decision is to fail to reject the null hypothesis.
Step-by-step explanation:
Since our significance level is α = 0.05, but since it's a two tailed test for two proportions, in each tail, we will have 0.05/2 = 0.025.
Now, the rejection region will be the critical value at 1 - 0.025 = 0.975
From the z-table attached, the critical value at 0.975 is 1.96.
Thus, our decision rule will be;
If Z-score is less than -1.96, or greater than 1.96, we will reject the null hypothesis.
Now, we have a z-score of z = 1.946 in the question. This lies between -1.96 and 1.96.
Thus,we will fail to reject the null hypothesis

An urn contains 5 red marbles 9 white and 7 blue marbles marbles.A child randomly selects three (without replacement) from the urn.Round to four decimal place.Find the probability all marbles are the same.
Answer:
0.0970
Step-by-step explanation:
Red marbles, R= 5
White, W = 9
Blue, B = 7
Total = (5 + 9 + 7) = 21
Selecting 3 marbles without replacement :
Probability that all marbles are the same
P(RRR) or P(BBB) or P(WWW)
(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)
0.0075187 + 0.0263157 + 0.0631578
= 0.0969922
= 0.0970

Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880
