Stephanie is a taxi driver. She rents her taxi for $300/week. She feels she can take in $120/day in fares. Let D be the number of days she drives her taxi in a week and T be the total earnings she expects after subtracting the rental charge.

a. Identify four ordered pairs (D,T).
b. Write an equation that gives T as a function of D.
c. What is the most she can earn in a year at this rate?

Answers

Answer 1

Answer: a. (0, -300), (1, -180), (2, -60), (7, 540)

b. T=120D-300

c. $28080

Step-by-step explanation:

a. T=120D-300 ==> per week

D=0: T=120(0)-300

D=0: T=-300 ==> (0, -300)

D=1: T=120(1)-300

D=1: T=120-300

D=1: T=-180 ==> (1, -180)

D=2: T=120(2)-300

D=2: T=240-300

D=2: T=-60 ==> (2, -60)

D=7: T=120(7)-300

D=7: T=840-300

D=7: T=540 ==> (7, 540)

b. T=120D-300

c. T=120(7)-300

T=840-300

T=$540 per week

1 year = 52 weeks

540*52=$28080

an envelope contains eight bills: two $ 1 bills, two $ 5 bills, two $ 10 bills, and two $ 20 bills. two bills are drawn at random without replacement. what is the probability that their sum is $ 20 or more? (a) 1 4 (b) 2 5 (c) 3 7 (d) 1 2 (e) 2 3

Answers

Probability is nothing but the ratio of favorable cases to all possible cases or in simple terms it is the ratio of sample set to all set

We are required to find all the cases in which sum of any two bills is 20$ or more

The total number of bills are two $ 1 bills, two $ 5 bills, two $ 10 bills, and two $ 20 bills.

The total case of drawing any two bills will be =

2 for $ 1 bill x two for 5$ bill x two for 10$ bill x two 20$ bills

=2 x 2x2x2 =16

Hence 16 ways in which two bills can be drawn at random

Cases in which bill can be greater than 20$= (1,20)(20,1)(5,20)(20,5)(10,10)(20,10)(10,20) (20,20)= 8 cases

Hence, total number of possible outcomes = 8

Hence the probability of bill to be 20$ or more= favorable outcome/total outcome

=8/16 =1/2

Hence the probability is 1/2

Answers

Answer:

V = 1 (Please mark the answer as brainliest)

Step-by-step explanation:

8(5 - 6v) = -7 - v

40 - 48v = -7 - v

40 = -7 + 47v

47 = 47v

1 = v

Answer:

v = 1

Step-by-step explanation:

Let's solve the problem,

→ 8(5 - 6v) = -7 - v

→ 40 - 48v = -7 - v

→ 40 + 7 = -v + 48v

→ 47v = 47

→ v = 47/47

Answers

The total volume of the solid = 1,035,000 cm³

What is the Volume of a Pyramid and a Cuboid?

Volume of a Pyramid = 1/3(length)(width)(height).

Volume of a cuboid = (length)(width)(height).

Volume of the Pyramid = 1/3(length)(width)(height)

Volume of the Pyramid = 1/3(90)(50)(240 - 225)

Volume of the Pyramid = 1/3(90)(50)(15)

Volume of the Pyramid = 22,500 cm³

Volume of the cuboid = (length)(width)(height)

Volume of the cuboid = (90)(50)(225)

Volume of the cuboid = 1,012,500 cm³

The total volume of the solid = 22,500 + 1,012,500

Answers

Rick will have to wash the plates for three minutes.

By first figuring out the value of a single unit and then multiplying the number by that value, the unitary approach in mathematics can be used to determine the required value.

• The unitary technique can be used to determine how many kilometres can be covered with 2 litres of gasoline, for instance, if a car goes 80 km on 6 l of fuel.

He washed 4 dishes in 2 minutes, thus we need to calculate how long it would take Rick to wash 6 plates. 4 plates, according to the rule, equals 2 minutes. Applying the unitary approach 1 plate in 2/4 of a minute 1 plate Equals 12 minute. 3 minutes equals 6 plates (12 times 6.6 plates).

∵AB⊥XY ∴BX=BY
∵XY=3cm ∴BX= ½XY=1.5cm
Let the radius be r cm.
then, OX=OY=OA=r cm
∵AB=3.5cm ∴OB=3.5cm-r cm
∵AB⊥XY ∴OB²+BX²=OX²
∴(3.5-r)²+1.5²=r² ∴r=29/14
So the answer is 29/14 (2.1).

Answer:

2.1 cm (nearest tenth)

Step-by-step explanation:

The radius (r) of a circle is the distance between its center and its circumference.  Therefore, from inspection of the given circle:

⇒ r = OX = OY = OA

Given:

AB = 3.5 cmOA = r

⇒ AB = OA + OB

⇒ 3.5 = r + OB

⇒ OB = 3.5 - r

As OX = OY and AB is perpendicular to XY then XB = BY.

As XY = 3 cm:

⇒ XB = BY = 1.5 cm

Therefore, for ΔOBX:

Leg a = OB = (3.5 - r) cmLeg b = XB = 1.5 cmHypotenuse = OX = r cm

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

a and b are the legs of the right triangle.c is the hypotenuse (longest side) of the right triangle.

Use Pythagoras Theorem and the defined sides of ΔOBX to find r:

[tex]\implies OB^2+XB^2=OX^2[/tex]

[tex]\implies (3.5-r)^2+1.5^2=r^2[/tex]

[tex]\implies 12.25-7r+r^2+2.25=r^2[/tex]

[tex]\implies 14.5-7r+r^2=r^2[/tex]

[tex]\implies 14.5-7r+r^2-r^2=r^2-r^2[/tex]

[tex]\implies 14.5-7r=0[/tex]

[tex]\implies 14.5=7r[/tex]

[tex]\implies 7r=14.5[/tex]

[tex]\implies \dfrac{7r}{7}=\dfrac{14.5}{7}[/tex]

[tex]\implies r=2.07142857...\: \sf cm[/tex]

What is Euclidean geometry?

Euclidean geometry is the study of geometrical shapes (plane and solid) and figures based on different axioms and theorems.

Now since Spherical geometry is the geometry of the two-dimensional surface of a sphere. In this context the word "sphere" refers only to the 2-dimensional surface and other terms like "ball" or "solid sphere" are used for the surface together with its 3-dimensional interior.

Euclidean geometry differs from spherical geometry because Euclidean Geometry are known to make use of a plane to be able to set points and lines, but Spherical Geometry are known to make use of spheres to set up points and great circles.

Thus, Euclidean geometry differs from spherical geometry because Euclidean geometry is used to set points by the use of plane.

Answers

Answer:

The equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.

Step-by-step explanation:

We have,

Spend on parking and admission = $235.75  

Spend on parking  = $6.25

Cost of ticket per person = $25.50

Let number of number of people = x

Now,

According to the question;

25.50x + 6.25 = 235.75

So, this the equation for number of number of people.

Now,

25.50x + 6.25 = 235.75

25.50x = 229.50

x = 9

So, number of number of people is 9, which we find out using the above mentioned equation.

Hence, we can say that the equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.

The number of people who can go to the amusement park is 9 they have $235.75 to spend on parking and admission. Parking is $6.25.

What is a linear equation?

A group of friends wants to go to the amusement park. They have $235.75 to spend on parking and admission.

Parking is $6.25, and tickets cost $25.50 per person, including tax.

Let x be the number of people

6.25 + 25.50x = 235.75

25.50x = 235.75 - 6.25

25.50x = 229.5

x = 9

[tex]2(p+w)[/tex] means, the plane speed, plus the windspeed, will take 2 hours to travel 450 KM. The reason we add the plane speed and the windspeed is because we have a tailwind instead of a headwind, the wind is pushing us forward, adding to the planes speed.

[tex]3(p-w)[/tex] means, the plane speed, minus the windspeed, will take 3 hours to travel 450 KM. We subtract the wind speed from the plan speed because the wind is a headwind, it's pushing us backwards, taking away from the planes speed.

The volume of a cuboid having health is double of the height and length is triple of the height is 1296 cm ³ find the area of base.​

Answers

The area of the base is 216 cm².

The volume of a cuboid is 1296 cm³.

The breadth of the cuboid is double the height of the cuboid and the length of the cuboid is triple the height of the cuboid.

Let the length, breadth, and height of the cuboid be l, b, and h respectively.

Then,

l = 3(h)

b = 2(h)

The volume of a cuboid is given as:

V = l × b × h

1296 = 3(h) × 2(h) × h

1296 = 6 × h³

h³ = 1296 / 6

h³ = 216

h = ∛216

h = ∛(6)³

h = 6 cm

Therefore, the length of the b is l = 3(h) = 3 × 6 = 18 cm

The breadth of the cuboid will be:

b = 2(h)

b = 2 × 6

b = 18 cm

Now the volume of the cuboid is also given as:

Volume = base area of  cuboid × height

1296 = base area × 6

base area = 216 cm²
