Sasha is collecting cans to recycle. When she collected 180 cans she knew she had reached 60% of her goal. How many more cans does Sasha need to collect to reach her goal?

Answers

So her goal is x after we make an equation you have .60+180=x so divide 180 into .60 to get 300 so I think she needs 300 more cans

Sasha needs to collect 120 more cans to reach her goal.

let us say the total goal is 100x

it is given that

when she collected 180 cans she knew she had reached 60% of her goal.

what is the percentage?

it is made up of two words 'per' and 'cent' means it is the value out of a hundred.

60% of 100x= 60x

60x = 180(given)

x=3

total goal = 100x= 100*3=300

total goal left= 300-180=120

therefore, Sasha needs to collect 120 more cans to reach her goal.

As input 20 relates to two different outputs 40 and 50 the relation is not a function.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

We know a relation is a function if it is one to one implies every input relates to different output or many one as different inputs lead to the same output.

The given information is represented by a diagram has one-to-many relations as the input 20 leads to the same output 50 so this is a one-to-many relation and not a function.

At 2 pm the machine starts working.
It makes 750 nuts and then changes to making bolts.
How many bolts will the machine make by 8.00 pm?

Answers

Answer:

3780 bolts will be made by 8pm

Step-by-step explanation:

One Hour : 500 nuts or 840 bolts

Divide by 2

30 minutes : 250 nuts or 420 bolts

750 nuts : 500 + 250 = 750

so the machine took 1 hour and 30minutes

14:00 it started (2pm)

15:30 it switched to bolts

20:00 (8pm)

4 hours and 30minutes to get to 8pm

840 × 4 = 3360 bolts + 420 bolts = 3780 bolts was made

Write the equation of the line represented by y =2/3x-5 in standard form

Answers

Answer:

2x-3y=15

Step-by-step explanation:

y=2/3x-5

2/3x-y=5

3(2/3x-y)=3(5)

2x-3y=15

The required equation of the line is represented by 2x-  3y = 15 in standard form.

What is the standard form of linear equations?

A linear equation is written in the standard form as Ax + By = C, where A, B, and C are integers and x and y are variables.

For example, 8x + 2y = 7 is the standard form of a linear equation in two variables.

The equation is given in the question

⇒ y = 2/3x - 5

We have to determine the standard form of the given linear equation

⇒ y = 2/3x - 5

⇒2/3x - y = 5

Multiply by 3 into both sides of the above equation,

⇒3(2/3x-y) = 3(5)

⇒2x - 3y = 15

Therefore, the required equation of the line is represented by 2x-  3y = 15 in standard form.

Answers

Answer: y = -1x + 2

Step-by-step explanation:

Points ( -3,5 )( 6,-4 )

You use the slope formula to find the slope.

Note: You'll need to learn the slope formula to make more sense of it, I suggest watching a video about it.

M = Y2 - Y1 over

      X2 - X1

Which is -4 - 5

               6 - -3 =         -9/9 = -1

The slope is -1

Now to find the y-intercept we use one of the x,y points ( I'll use 6,-4 )

And plug them in

-4 = -1(6) + b

-4 = -6 + b

+6   +6

2 = b

The equation will be y = -1x + 2

Answers

Answer:

Step-by-step explanation:

Since the sum of all interior angles of a triangle is 180 degrees, we are able to derive the answer of what x (m<1 in this case) measures.

For example, in number 1, you can do

m<1 = 180 - 94 - 45

For the 2nd one, the tick marks show that the highlighted angles measure the same.

So, it would be (180-58)/2 = m<1

Finally, for the third one, there is a right angle, meaning that it measures 90 degrees

Therefore, 180-90-77 = m<1

- El resultado de la conversión de 350 km/h a m/s es:
A. 1.26x10 m/s
B. 1260 m/s
C. 97.22 m/s​

Answers

Answer:

350 kilómetros por hora son 97,2222 metros por segundo ;)

The result of converting 350 km/h to meter per second is 97.22 m/s.

To convert from kilometers per hour (km/h) to meters per second (m/s), you need to apply the conversion factor.

The conversion factor for this conversion is 1 km/h = 0.2778 m/s.

To convert 350 km/h to m/s, multiply 350 by the conversion factor:

350 km/h×0.2778 m/s

= 97.22 m/s

Therefore, the result of converting 350 km/h to m/s is approximately 97.22 m/s.
