Answers

Answer 1

Answer:

34.5

Approximately= 35

Step-by-step explanation:

The ratio of the number of boys= 8

Ratio of number of girls= 5

Total ratio= 8+5=13

number of boys in that class =52

Let total number of students= X

Ratio of number of boys= 8/13 × X=52

= 8X/13 = 52

8X=13 × 52

8X= 676

X= 84.5

Then, the number of girls= (84.5-50)

34.5

Answer 2

Answer:

the answer is 84.5-50 is the answer

Now describe a situation involving area in square feet that can be modeled using the function g(x) = 2x2 − 13x + 6 so that it relates to last situation you came up with.

Answers

Answer:

[tex]Length = 2x - 1[/tex]

[tex]Width = x - 6[/tex]

Step-by-step explanation:

Given

[tex]g(x) = 2x^2 - 13x + 6[/tex]

Required

Model as the area

[tex]g(x) = 2x^2 - 13x + 6[/tex]

Expand:

[tex]g(x) = 2x^2 - 12x -x+ 6[/tex]

Factorize:

[tex]g(x) = 2x(x - 6) -1(x- 6)[/tex]

[tex]g(x) = (2x - 1) (x- 6)[/tex]

Area is calculated as:

[tex]Area = Length * Width[/tex]

So, by comparison:

[tex]Length = 2x - 1[/tex]

[tex]Width = x - 6[/tex]

Answer:

Based on the situation in part A, the width of a rectangular garden is x feet, and its length is 5 feet more than twice its width. The right side of the equation, g(x) = 2x2 − 13x + 6, can be factored to g(x) = (2x − 1)(x − 6). This function could represent an inner region of the garden from the first equation, such as a vegetable garden with a border around it. The length of this inner garden would be 2x − 1 feet, and the width would be x − 6, which would leave a 3-foot border around the garden.

New Orleans averages 77% humidity in the mornings, but it decreases by 20% in the afternoon. What is the average relative humidity in the afternoon in New Orleans? (enter a percent rounded to the tenths place)

Answers

Answer: 61.6%

Step-by-step explanation:

The afternoon humidity average is 20% of the morning average.

The morning average is 77% so the afternoon average must be:

= Morning average * ( 1 - percentage decrease)

= 77% * 80%

= 61.6%

Rewrite the following equation in slope-intercept form.

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

Slope-intercept form is

y = mx + b

We want to get the y by itself on one side of the equation.

0 = 18x + 6y – 2

First let's subtract 6y from both sides.

-6y = 18x – 2

Next let's divide both sides by -6.

y = (18 / -6)x - (2 / -6)

y = -3x + 1/3

What will a $160,000 house cost 8 years from now if the price appreciation for homes over that period averages ​7% compounded​ annually?

Answers

Answer:

Step-by-step explanation:

We will use the A=P*(1+r/n)^nt formula

P = 160,000

R = the rate 7%

N= the times compounded. Since it is annually it is 1

T = 8 years

Filling in the information...

A = 160,000 x (1 + .07)^1*8

   = 160,000 x 1.07^8

   = 160,000 x 1.71818617983

   = 274909.788773
