Thirty is 60% of what number

Answers

Answer 1

Answer: When you see 'is' that means an = sign
When you see 'of' that means a x (multiplication) sign

So

30 is 60% of what number

Let us define this 'what number' as x.

So:

30 is 60% of x

Translating that into an equation based on what I said above, we get:

$\sf{30 = (60)/(100)* x}$

Solve for x:

$\sf{(30*100)/(60)=x$

And simplfying that:

$\sf{x=50}$

So your final answer is $\sf{\boxed{50}}$

Snapchat : 10 + 30 = 40
Instagram : 40 + 20 = 60

Stefanie is painting her bedroom. She can paint 12 and 2/3 square feet in 2/5 of an hour. How many square feet can she paint in one hour?

Answers

The number of square feet that she can paint in one hour will be 31.67 square feet per hour.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Stefanie is painting her bedroom. She can paint 12 and 2/3 square feet in 2/5 of an hour.

The total number of squares is given as,

Area = 12 + 2/3

Area = 38/3 square feet

Then the number of square feet that she can paint in one hour is given as,

Rate = (38/3) / (2/5)

Rate = (38 x 5) / (2 x 3)

Rate = 31.67 square feet per hour

The number of square feet that she can paint in one hour will be 31.67 square feet per hour.

Answer:

31 2/3 .

Step-by-step explanation:

To find how many square feet Stefanie can paint in one hour, divide the number of square feet by the fraction of an hour:

12 2/3 divided by 2/5 = 38/3 divided by 2/5.

=38/3 times 5/2

=190/6

=31 2/3 .

Answer: LAST OPTION.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

Find the slope of the line with this formula:

$m=(y_2-y_1)/(x_2-x_1)$

Choose two points from the table and substitute the coordinates into the formula. Then, the slope is:

$m=(40-45)/(3-0)=-(5)/(3)$

By definition, the line intersects the y-axis when the value of "x" is zero ( $x=0$ ).

Based on the table, the y-intercept is:

$b=45$

Then the equation of the line is:

$y=-(5)/(3)x+45$

The line intersects the x-axis when the value of "y" is zero ( $y=0$ ), then you can substitute these value into the equation and solve for "x":

$0=-(5)/(3)x+45\n\nx=27$

So, you get the point:

$(27,0)$

Since the table shows the distance from the bus stop as a function of time, you can conclude that meaning of the x-intercept in this scenario is: "The distance away from the bus stop".

Answer: (27, 0); the distance away from the bus stop
