If 5/8 of the people in a water aerobics class are over age 65 and 1/4 of the people in the class are under age 40, what fraction of the people in the class are either over 65 or under 40?

Answers

Answer 1

Answer:

7/8

Step-by-step explanation:

You just need to add the two fractions together. Since no one can be both, no  other revision is needed.

5/8 + 1/4 = 5/8 + 2/8 = 7/8

The measures of two angles are represented by the expressions (5x + 24)° and (9x − 17)°. If the two angles are equal, what is the value of x?

Answers

Answer:

x=10.25

Step-by-step explanation:

Angle 1 = (5x+24)°

Angle 2 = (9x-17)°

The two angles are equal. It means,

(5x+24)°=(9x-17)°

Taking like terms together,

5x-9x=-17-24

-4x=-41°

Dividing each side by -4

x=10.25°

So, the value of x is 10.25.

Answer:

[tex](f\circ g)(4)=31[/tex]

Step-by-step explanation:

Composite Function

Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:

[tex](f\circ g)(x)=f(g(x))[/tex]

For practical purposes, it can be found by substituting g into f.

We have:

[tex]f(x)=3x+1[/tex]

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

Computing the composite function:

[tex](f\circ g)(x)=f(g(x))=3(x^2-6)+1[/tex]

Operating:

[tex](f\circ g)(x)=3x^2-18+1[/tex]

Operating:

[tex](f\circ g)(x)=3x^2-17[/tex]

Now evaluate for x=4

[tex](f\circ g)(4)=3(4)^2-17=48-17[/tex]

[tex]\boxed{(f\circ g)(4)=31}[/tex]

The height of an Egyptian pyramid is 146.5 meters and its base is 230.38 meters. Find the slope of the face of a pyramid.

Answers

Answer:

[tex]Slope = 1.57[/tex]

Step-by-step explanation:

Given

[tex]Height = 230.38\ m[/tex]

[tex]Base = 146.5\ m[/tex]

Required

Determine the slope

Slope is calculated as thus:

[tex]Slope = Rise/Run[/tex]

In this case:

[tex]Rise = Height = 230.38 m[/tex]

[tex]Run = Base = 146.5 m[/tex]

So, we have:

[tex]Slope = 230.38 / 146.5[/tex]

[tex]Slope = 1.57[/tex] (approximated)

The Lake Placid Town Council decided to build a new community center to be used for conventions, concerts, and other public events, but considerable controversy surrounds the appropriate size. To provide structure for the decision process, the council narrowed the building alternatives to three sizes: small, medium, and large. Everybody agreed that the critical factor in choosing the best size is the number of people who will want to use the new facility. The town council suggested using net cash flow over a 5-year planning horizon as the criterion for deciding on the best size. The following projections of net cash flow (in thousands of dollars) for a 5-year planning horizon have been developed.All costs, including the consultant's fee, have been included.
Demand Scenario
Center Size Worst Case Base Case Best Case
Small 400 500 660
Medium -250 650 800
Large -400 580 990
a) What decision should Lake Placid make using the expected value approach?
b) Construct risk profiles for the medium and large alternatives. Given the mayor's concern over the possibility of losing money and the result of part (a), which alternative would you recommend?
c) Compute the expected value of perfect information. Do you think it would be worth trying to obtain additional information concerning which scenario is likely to occur?

A recipe for salad dressing calls for 4 parts oil for every 3 parts vinegar.How much oil should you use to make a total of 28 teaspoons of dressing

Answers

Answer:

16 teaspoons

Step-by-step explanation:

4x4= 16 teaspoons

The amounts of oil and vinegar combined to make the salad dressing are

in a constant definite proportion.

The quantity of oil required to make 28 teaspoons of dressing is 16

teaspoons.

Reasons:

According to the question, 4 parts of oil are added to every 3 parts of

vinegar.

Therefore;

The ratio or proportion of oil to vinegar in the salad dressing is 4 : 3

4 : 3 = [tex]\dfrac{4}{3}[/tex]

The proportion of oil to vinegar is therefore;

[tex]\mathrm{Amount \ of \ oil = \mathbf{\dfrac{4}{3} \times \ Amount \ of \ vinegar}}[/tex]

Which gives;

[tex]\mathrm{Amount \ of \ vinegar= \dfrac{3}{4} \times \ Amount \ of \ oil}[/tex]

Let x represent the amount of oil required to make 28 teaspoons of dressing,

we have;

[tex]\mathrm{Amount \ of \ vinegar \ required = \dfrac{3}{4} \times x}[/tex]

Which gives;

[tex]\mathrm{x + \dfrac{3}{4} \times x = 28}[/tex]

[tex]\mathrm{x + \dfrac{3}{4} \times x = \dfrac{7}{4} \times x = 28}[/tex]

Therefore;

[tex]x = \dfrac{4}{7} \times 28 = \dfrac{4}{7} \times 7 \times 4 = 4 \times 4 = 16[/tex]

The amount of oil required to make 28 teaspoons of dressing, x = 16 teaspoons.
