Mathematics

Answer:

H = 13.67

Step-by-step explanation:

Given:

The the algebraic expression is

H + \frac{340}{30} = 25

We need to write the above equation for h.

Solution:

H + \frac{340}{30} = 25

First we divide the fraction part of the equation by common factor 10.

H + \frac{34}{3} = 25

Subtract both side of the equation by \frac{34}{3}.

H + \frac{34}{3}-\frac{34}{3} = 25- \frac{34}{3}

H = 25- \frac{34}{3}

To write  25  as a fraction with a common denominator, multiply by \frac{3}{3}.

H = 25\times \frac{3}{3}- \frac{34}{3}

H = \frac{25\times3}{3}- \frac{34}{3}

H = \frac{75}{3}- \frac{34}{3}

H = \frac{75-34}{3}

H = \frac{41}{3}

H = 13.67

Therefore the value of H is 13.67.

The highest rated of the four European cities under consideration: This can be done by multiplying factor and importance and sum
arlik [135]

Answer:

The question is not complete, as the table containing the data is missing, but I found a matching table that can be used to answer the question.

The Question is:

Which is the highest rated, of the four European cities under consideration, using the table.

The correct answer is: City A is the highest rated European city.

Step-by-step explanation:

The highest rated European city can be found by multiplying the factor and the importance of the factors, and summing up their final values. the cty with the highest number is the one with the highest rated city. Having this in mind, let us calculate the ratings for each of the cities as follows:

City A:

(70 × 20) + (80 × 20) + (100 × 20) + (80 × 10) + (90 × 10) + (65 × 10) + (70 × 10) = 1400 + 1600 + 2000 + 800 + 900 + 650 + 700 = 8050

City B:

(70 × 20) + (60 × 20) + (50 × 20) + (90 × 10) + (60 × 10) + (75 × 10) + (60 × 10) = 1400 + 1200 + 1000 + 900 + 600 + 750 + 600 = 6450

City C:

(60 × 20) + (90 × 20) + (75 × 20) + (65 × 10) + (50 × 10) + (85 × 10) + (65 × 10) = 1200 + 1800 + 1500 + 650 + 500 + 850 + 650 = 7150

City D:

(90 × 20) + (75 × 20) + (90 × 20) + (65 × 10) + (70 × 10) + (70 × 10) + (80 × 10)   = 1800 + 1500 + 1800 + 650 + 700 + 700 + 800 =7950

Therefore, from the ratings computed above, City A with a rating of 8050, is the highest rated, while City B with a rating of 6450, is the lowest rated.

The domain of the function, y=2x+4 is {3, 5,6,8}. Identify the range
polet [3.4K]

Domain is the x-values

Range is the y-values

To identify the range, plug in the x-values they gave you into the equation to find its y-value

x = 3

y = 2x + 4       Plug in 3 for x

y = 2(3) + 4

y = 10

x = 5

y = 2x + 4    Plug in 5 for x

y = 2(5) + 4

y = 10 + 4

y = 14

x = 6

y = 2x + 4       Plug in 6 for x

y = 2(6) + 4

y = 16

x = 8

y = 2x + 4      Plug in 8 for x

y = 2(8) + 4

y = 20

The range is {10, 14, 16, 20}
