Answer:

0.5%/year

24.2%

Step-by-step explanation:

Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation

Percentage of females by year:

1980 = 6.2%

1990 = 10.8%

2000 = 13.6%

2012 = 21.7%

Average yearly increase :

Percentage increase between 1980 - 2012 :

2012% - 1980% = ( 21.7% - 6.2%) = 15.5% increase over [(2012 - 1980)] = 32 years

15.5 % / 32 years = 0.484375% / year = 0.5%/year

b. Estimate the percentage of first-year college females who will claim no religious affiliation in 2030,

Given an average increase of 0.484375% / year

(2030 - 1980) = 50 years

Hence by 2030 ; ( 50 years × 0.484375%/year) = 24.218% will claim no religious affiliation.

=24.2% (nearest tenth)

In this exercise we have to use the percentage knowledge to calculate an estimate per year, in this way we find that;

A) \(0.5\%/year\)

B) \(24.2\%\)

Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation.  Percentage of females by year:

\(1980 = 6.2\%\\1990 = 10.8\%\\2000 = 13.6\%\\2012 = 21.7\%\)

A) Average yearly increase  can be caculeted by:

\(2012\% - 1980\% = ( 21.7\% - 6.2\%) = 15.5\% = 32 years \\15.5 \% / 32 years = 0.484375\% / year = 0.5\%/year\\\)

B)  Estimate the portion of first-old age institution of higher education woman the one will claim no religious association with an organization fashionable 2030, Given an average increase of:

\((2030 - 1980) = 50 years\\ ( 50 years * 0.484375\%/year) = 24.2\%\)

Answer:

27 units

Step-by-step explanation:

Answer:

VW = 27 units

Step-by-step explanation:

the opposite sides of a rectangle are equal , then

perimeter = 2(3x - 3) + 2(2x + 3)

                 = 6x - 6 + 4x + 6

                 = 10x

given perimeter = 100 , then

10x = 100 ( divide both sides by 10 )

x = 10

Then

VW = 3x - 3 = 3(10) - 3 = 30 - 3 = 27 units

Answer:

$5.40

Step-by-step explanation:

First, find Dave's purchase. To do this, you multiply 15 by the tax percent and add that to the original.

So:

15 x 8% = 15 x 0.08 = 1.2

15 + 1.2 = 16.2

Next, do the same for Mel's purchase:

20 x 8% = 20 x 0.08 = 1.6

20 + 1.6 = 21.6

Then, you subtract Dave's purchase from Mel's:

21.6 - 16.2 = 5.4

This comes out to $5.40

The interest accumulated in the account after the first and second year indicates;

The amount Miguel originally put into the bank is about $728

An interest is a reward or cost of borrowing or lending money.

Let P represent the amount Miguel deposited in the bank, and let r represent the interest rate in percentage, therefore, we get;

The amount in the account after the first year is; P + r·p = P·(1 + r)

P·(1 + r) = $757.12...(1)

The amount in the account after the second year can be obtained using the following formula;

Principal at the start of the second year = P·(1 + r)

Therefore; Amount = P·(1 + r)  + P·(1 + r) × r = P·(1 + r) × (1 + r) = P·(1 + r)²

P·(1 + r)² = $787.40...(2)

Equation (1) indicates that we get; (1 + r) = 757.12/P

Therefore; P·(1 + r)² = P·(757.12/P)² = 787.40

757.12²/P = 787.40

P = 757.12²/787.40 ≈ 728

The amount Miguel deposited in the bank is about $728

Answer:

Step-by-step explanation:

B is right because she is earning money, so the slope would have to be positive.

Next, the y-intercept of the 300 needs to be negative because she does not have the money to start with. It is also negative because you can think of it that you are subtracting the final babysitting money with 300.

Answer:

y = 25x - 300

Step-by-step explanation:

She has to save up 25 PER week and once she has enough, you subtract 300 since that's the cost of the bike

Step-by-step explanation:

so, we calculate the perpendicular slope, and then we start with the point-slope form (since we were given a specific point of the line), and transform into the regular slope-intercept form.

the slope in

y = 2x + 2

is the factor of x : 2 or 2/1

the perpendicular slope is turning this upside down and flips the sign : -1/2

the point- slope form is

y - y1 = a(x - x1)

"a" being the slope, (x1, y1) being the point.

y - 9 = -1/2(x - -2)

y - 9 = (-1/2)x - 1

y = (-1/2)x + 8

The values of tht missing part of the triangle are;

A= 20.9°

a = 13.06

c = 33.6

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

To find side c

sinB/b = sinC/c

sin45.9/26.30 = sin113.2/c

csin 45.9 = 26.30 × sin113.2

0.718c = 23.90

c = 23.90/0.718

c = 33.6

Angle A = 180-(113.2+ 45.9)

angle A = 20.9°

sinA/a = sinB/b

sin20.9/a = 0.718/26.30

0.357 × 26.30 = 0.718a

Answer:

Step-by-step explanation:

The angle measure explained in the solution.

Given that, a || b, we need to find the missing angles,

∠1 = 42° [vertically opposite angles]

∠3 = 62° [vertically opposite angles]

∠2 = 180°-(∠1+62°) [angle in a straight line]

∠2 = 76°

∠4 = ∠2 [vertically opposite angle]

∠4 = 76°

∠4 = ∠9 = 76° [alternate angles]

∠9 = ∠12 = 76° [vertically opposite angle]

∠3 = ∠ 6 = 62° [alternate angles]

∠ 6 = ∠7 = 62° [vertically opposite angle]

∠3 + ∠5 = 180° [consecutive angles]

∠5 = 118°

∠5 = ∠8 = 118° [vertically opposite angle]

∠4 + ∠10 = 180° [consecutive angles]

Step-by-step explanation:

QM is parallel to NR so we can say

angle MQP = angle NRP and

angle QMP = angle PNR

(Alternate angles)

Question also shows that Line QM = Line NR

So the two triangles PMQ and PNR are congruent by Angle Side Angle (ASA)

To analyze the relationship between the slopes of two lines, specifically the slope of line AB and the slope of the perpendicular line through point C, we need to consider the properties of perpendicular lines.

If line AB and the perpendicular line intersect at point C, then the slopes of these two lines are related by the concept that the product of their slopes is equal to -1. In other words, the slopes of perpendicular lines are negative reciprocals of each other.

Let's denote the slope of line AB as m_AB and the slope of the perpendicular line through point C as m_perpendicular. If the slopes are related by the property of perpendicular lines, we have the equation:

\(m_AB * m_perpendicular = -1\)

This relationship holds true for any pair of perpendicular lines.

For example, if the slope of line AB is 2/3, then the slope of the perpendicular line through point C would be -3/2. The product of these slopes (-3/2 * 2/3) is indeed equal to -1, confirming the perpendicularity of the lines.

This property of perpendicular lines and their slopes arises from the geometric interpretation of slopes. The slope of a line represents the ratio of vertical change (rise) to horizontal change (run).

When two lines are perpendicular, one has a positive slope while the other has a negative slope, and their ratios of rise to run are reciprocals of each other. This reciprocal relationship ensures that the product of their slopes is -1.

In conclusion, the relationship between the slopes of perpendicular lines is that they are negative reciprocals of each other. This property provides a convenient way to determine the slope of a perpendicular line given the slope of another line, facilitating calculations and geometric analysis involving perpendicularity.
