Answers

Answer:

600 square feet

Step-by-step explanation:

I notice it says "Estimate" in bold. Therefore, you would round all of the measurements. They're all pretty simple to round (to the nearest tens place). From here, you subtract the length of the large room from the length of both rooms. So, 50 - 30 = 20. This is the length of the small room. We now multiply this by the width of the small room (since area of a rectangle is length * width) and we get:

20 * 30 = 600, our final answer

Hope it made sense. I would appreciate Brainliest, but no worries.

how do I find the value of a in 30=5a​

Answers

Answer:

a = 30/5 = 6

Step-by-step explanation:

Answer:

a = 6

Step-by-step explanation:

You need to try to get "a" alone.

So, since the equation shows a is being multiplied by 5, you need to divide it by 5 to get "a" alone.

Whatever you do to one side, you must do the same to the other side.

So basically, you divide both sides by 5 to find "a"

Answers

Step-by-step explanation:

Start at the orgin.

The y intercept in the equation is -1 so I would shift 1 unit down to the orgin at (0,-1)

Then at the point, since the slope is -4. I would go down -4 units then go over 1 unit to the right.. So the next point would be (1,-5) then so on and so on.

You can check if your graph is correct by writing out specific points on the linear equation and making sure there slope is equal to -4.

Answer:

4x + 2.5y = 184

x = y - 6

Step-by-step explanation:

Let the number of smoothies sold by stand = x

And number of cones sold = y

If the selling price of each cone = $2.5

Selling price of the 'y' cones = $2.5y

Selling price of each smoothies = $4

Then sales of smoothies = $4x

If the total sales of one day = $184

Equation for this situation will be,

4x + 2.5y = 184 -------(1)

If the stand sold 6 less smoothies than the cones,

x = y - 6 -----(2)

Therefore, system of equations contains two equations (1) and (2).

A building 220 feet casts a 100 foot long shadow. If a person stands at the end of the shadow and looks up to the top of the building, what is the angle of the personas eyes to the top of the building? 62.14 65.56 64.95 27.86

Answers

Answer:

65.56°

Step-by-step explanation:

= We solve the above question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

Opposite = 220 feet = Height of the building

Adjacent = 100 feet = Length of the shadow

Hence,

tan θ = 220/100

tan θ = 2.2

= arctan(2.2)

= 65.55604522°

Approximately = 65.56°
