1. This problem lacks given values, where are the numbers? Just fill-in the numbers I will variables in this case.

Let us say that:

x = number of cups of flour

y = number of cups of white sugar

z = number of cups of brown sugar

(a) Just divide x by 6 to get cups of flour per serving

x / 6

(b) Simply add y and z and divide the sum by 6

(y + z)/6

(c) From (a) we know that there are x / 6 flours per serving, so simply multiply that by 9 then subtract the original x to know how much more you need:

[(x / 6) * 9] – x

 

2.

(a) We know that we deposit $5 per day, so after 5 days we got:

total deposit = ($5 / day) * 5 days = $25

(b) The total deposit is 25 dollars, so removing $2 a day we need:

25 / 2 = 12.5 days

 

3.

(a) d is distance, R is rate, T is time

32.12 = 8.8 T

(b) It is rightful to write distance d as a positive number since the scuba diver was ascending towards the surface. If this is to be plotted on a Cartesian plane, we are moving towards the positive y axis

(c) solving for T:

32.12 = 8.8 T

T = 32.12 / 8.8

T = 3.65 minutes

what is the equation of the line, in point-slope form, that passes through the given point and has the given slope ? point (7,3)
Maru [420]

Answer:

y-3 = 4/7(x-7)

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1)

We know the slope (4/7)

and a point (7,3)

Lets substitute into the equation

y-3 = 4/7(x-7)

A common practice of airline companies is to sell more tickets for a particular flight than there are seats on the​ plane, becau
Serga [27]

Answer:

0.0159

Step-by-step explanation:

Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the​ plane, because customers who buy tickets do not always show up for the flight.

Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)

The plane is overbooked if more than 150 show up

i.e. less than 2 do not show up

Hence  the probability that the airline overbooked this​ flight

=P(X

Suppose that y varies directly with x, and y=15 when x=24. Write a direct variation equation that relates x and y. Find y when x
Lapatulllka [165]

Just set up a proportion with the original numbers and then the numbers you want to find like so: (x1/y1)=(x2/y2) and since you want to find the second y value, just leave y as a variable like so: (15/24)=(3/y) after this just cross multiply and get the answer: 15y=72.....y=4.8

Answer: the distance of the boat from the foot of the lighthouse is 290.5 feet.

Step-by-step explanation:

The right angle triangle ABC representing the scenario is shown in the attached photo.

Angle A is alternate to the angle of depression, hence, they are the same.

The height of the lighthouse represents the opposite side of the right angle triangle. The distance, x of the boat from the foot of the lighthouse represents the adjacent side of the right angle triangle.

To determine x, we would apply

the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan 11.1 = 57/x

x = 57/Tan 11.1 = 57/0.1962

x = 290.5 feet to the nearest tenth.
