What is the distance of the​ run? What is the distance of the bicycle​ race?

Answers

Answer 1

Answer:

so the answer will be 1

Step-by-step explanation:

An oil tanker can be emptied by the main pump in 5 hours.

An auxilary pump can empty the tanker in 14 hours.

If the main pump is started at 7pm, when should the auxilary pump be started

so that the tanker is emptied by 11pm?

:

Let t = no. of hrs to run the Aux pump

:

The main pump will run 4 hr (7 - 11 pm)

:

Let the completed job = 1; (an empty Tanker)

:

The shared work equation

4%2F5 + t%2F14 = 1

Multiply equation by 70 to get rid of the equation, results:

14(4) + 5t = 70

56 + 5t = 70

5t = 70 - 56

5t = 14

t = 14%2F5

t = 2.8 hrs to run the aux pump

:

2.8 hr = 2 + .8(60) = 2 hrs 48 min

:

Subtract 2:48 from 11:00 = 8:12 PM start the aux pump

;

;

Check solution

4/5 + 2.8/14 =

.8 + .2 = 1

A Spanish teacher informed her class that she would be giving 4 quizzes each month. Write an equation that shows the relationship between the number of months elapsed, x, and the total number of quizzes, y.

Answers

Answer:

y = 4x

Step-by-step explanation:

Since there are going to be four quizzes a month (x), we know that we will multiply the number of months (x) by the number of quizzes (4). However, because we don't know how many months there are, we can define the months as (x), and instead put the total (y) is equal to the number of quizzes per month (4), multiplied by the number of months (x). Out final result is

(y = 4x)

#13. line QR is 26.

#14. a) x = 2 b) m = 6

Step-by-step explanation:

13. We can use the Pythagorean therom: a^2 + b^2 = c^2

We will substitue PQ for a and PR for b

10^2 + 24^2  = c^2

100 + 576 = c^2

100 + 576 = 676

Then, we find the square root of 676, which is 26.

14. a) 3(2x -1) = 9

we first use distributive property:

6x - 3 = 9

then we add 3 to both sides to counteract the -3:

6x = 12

we divide both sides by 6 to get x alone:

x = 2

b) 3m - 12 = 6

we add 12 to both sides to counteract the -12:

3m = 18

we divide both sides by 3:

m = 6

En un parqueadero hay 50 vehículos. Pero si contamos sus llantas hay 140.¿Cuántos carros y motos hay? Por favor alguien que me ayude este tema es de matemáticas problemas lineales 2x2

Answers

Answer:

Carros = 20

Motos = 30

Step-by-step explanation:

Carros = x

Motos = y

x + y = 50

4x + 2y = 140

x = 50 - y

4 (50-y) + 2y = 140 (substitución)

200 - 4y + 2y = 140

- 2y = 140 - 200

y = -60/-2

y = 30

x + 30 = 50

x = 50-30

x = 20

a model of a ship is made to a scale of 1:200
the surface area of the model is 7500 cm²
calculate the surface area of the ship, giving your answer in square meters

Answers

The surface area of the ship is 1500000 cm²

Scaling is used to either increase or decrease the size of a figure so as to create an image.

Given a scale of 1:200, this means that it is a scaling down (decrease in size) of the ship to create a model.

The surface area of the model is 7500 cm², hence that of the ship is:

Surface area of ship * (1 : 200) = surface area of model

Surface area of ship = surface area of model * 200 = 7500 * 200 = 1500000 cm²

The surface area of the ship is 1500000 cm²

So 5t+6 = 41, 41-6 is 35. 35/5 is 5, so t is 5.

A tennis racket with a price of $180 is subject to a sales tax of 7%. What is the total
price of the racket?
$192.60
$187

Answers

The total price of the racket is $192.60 (first option).

What is the total price?

A tax is a compulsory amount of money that is levied by the government or an agency of the government on goods and services. A sales tax is levied on the sales of goods and services.

The total price of the racket would include the amount of tax that would be paid.

Total price = (1 + tax/100) x initial price

Total price = (1 + 7%/100) x $180

Total price = (1 + 0.07) x $180

Total price = (1,07 x $180)  

Total price = $192.60
