Solve the equation :6/x+10=2/15

Answers

Answer:

x = - 45 / 74

Step-by-step explanation:

6 / x + 10 = 2 / 15

6 / x = 2 / 15 - 10

6 / x = 2 / 15 - 150 / 15

6 / x = - 148 / 15

6 = ( - 148 / 15 ) x

6 ( 15 / - 148 ) = x

x = 90 / - 148

x = - 45 / 74

Two Grade 7 students, Monique and Matt, both solved the following math problem: If the temperature drops from 7°F to -17°F, by how much did the temperature decrease? The students came up with different answers. Monique said the answer is 24°F, and Matt said the answer is 10°F. Who is correct? Explain, and support your written response with details .
​

Answers

Answer: It decreased by 24F not 10F because if it were 10F the starting temperature had to be -7F since the difference between this number and -17F is 10F but in this case it starts at 7F so we subtract 7-0=7 and 17-0=17 and add 17+7=24F.

Step-by-step explanation:

7-0=7

17-0=17

17+7=24F

The change in temperature is -24°F.

Monique said the answer of 24°F is true.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Let f(x) = 5x-7 and g(x) = 2x-3. Find f(x)+g(x)

Answers

Answer:

7x - 10

Step-by-step explanation:

f(x)= 5x - 7

g(x)= 2x - 3

f(x) + g(x)

= 5x - 7 + 2x - 3

= 7x - 10

The sum of f(x) and g(x) is 7x - 10.

To find the sum of f(x) and g(x), you simply need to add the two functions:

f(x) + g(x) = (5x - 7) + (2x - 3)

Now, combine like terms:

f(x) + g(x) = 5x + 2x - 7 - 3

f(x) + g(x) = 7x - 10

Therefore, the sum of f(x) and g(x) is 7x - 10.

During the year, the company started and completed only two jobs-- Alpha, which used 62,300 direct labor-hours, and Job Omega. The job cost sheets for the these two jobs are shown below.

Step-by-step explanation:

Note: Question is incomplete and similar question is attached as picture below

sally runs 5km in 25 minutes. she plans to run in 20 km race. based on the current speed how long will it take her to complete the race?

Answers

Given:

Sally runs 5km in 25 minutes.

Total distance of race = 20 km

To find:

How long will it take her to complete the race?

Solution:

We have,

Time taken by Sally for 5 km = 25 minutes

Time taken by Sally for 1 km = [tex]\dfrac{25}{5}[/tex] minutes

                                               = 5 minutes

Time taken by Sally for 20 km = [tex]20\times 5[/tex] minutes

                                               = 100 minutes

                                               = 1 h 40 minutes               [ 1 h = 60 min]

Therefore, the time taken by Sally to complete the race is 1 h 40 minutes.

If m is the midpoint of CD, CM= 4x-5, and md=2x +5, find CM

Answers

Answer:

CM = 15

Step-by-step explanation:

since M is the midpoint of CD , then

CM = MD , that is

4x - 5 = 2x + 5 ( subtract 2x from both sides )

2x - 5 = 5 ( add 5 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Then

CM = 4x - 5 = 4(5) - 5 = 20 - 5 = 15

Answer:

Step-by-step explanation:

The "experimental probability" is the ratio of actual outcomes of interest to the number of trials. It is based on actually performing the selection over and over some number of times. The "theoretical probability" will be the fraction that is the outcomes of interest divided by the total number of possible outcomes.

We note that Mel's purse contains a total of 6 +8 +4 +7 = 25 coins. The theoretical probability of selecting any given coin is then 1/25.

A. The experimental probability of selecting a dime is ...

  number of dime outcomes / number of trials = 30/150 = 1/5

B. The theoretical probability of selecting a dime is ...

C. The assumption in probability experiments is that randomly selected outcomes will always approach the theoretical probability in their frequency of occurrence.

A cylinder trash can is 30in high and has a base radius of 7in. a manufacturer wants to know the surface of this trash can, including the top of the lid.

Answers

The surface area of the given cylinder trash can is 1,628 in²

The surface area of a cylinder is equal to the area of curved surface plus the area of flat surfaces. The flat surfaces are the base and the lid.

Area of the curved surface = 2 π.r.h

Area of the flat surfaces = 2 π.r²

Hence,

Total surface area of a cylinder = 2 π.r.h + 2 π.r²

                                                 = 2 π.r (h + r)

Where:

h = height

r = radius of the base

Parameters given:

h = 30 in.

r = 7 in.

Substitute these parameters into the formula:

Area = 2. (22/7) . 7. (7 + 30)

Answers

The area of the given figure is 100 cm².

In the above figure, we calculate total area by dividing the figure into two sub figures wherein we get a square portion of side 5 cm and a rectangular portion of length 15cm and breadth 5 cm. The area of the square and rectangle can be given as product of their two sides that is length multiplied by breadth.

Area of square portion = 5*5 = 25 square centimeter

Area of rectangular portion =15*5 = 75 square centimeter

Hence total area of the figure = Area of square portion + Area of rectangular portion.

Therefore, Total area of figure = 25 + 75 = 100 cm².
