Answer:

464

Step-by-step explanation:

\frac{27}{125} = \frac{216}{1000}

\frac{40}{125} = \frac{320}{1000}

216+320 = 536

1000-536 = 464

Answer:

The second one

Step-by-step explanation:

A linear function will always increase or decrease by the same amount:

The first one adds eight for every increase of 1 in the x value

The third one subtracts three for every increase of 1 in the x value

However,

The second one starts by adding three, and then adds 1.5 for the rest

The second table is nonlinear

Which represents a function?
ollegr [7]

Answer:

Only the given table represents a function. Option 1 is correct.

Step-by-step explanation:

A relation is called a function, if there exist a unique value of y for each value of x. It means for each input there exist a unique output.

A function is always a relation but all relations are not function.

In the given table for each value of x, we have unique value of y, therefore the given table represents a function.

In second relation, at x=-2, the values of y are y=10 and y=-7. For single x, there are more than one value of y, therefore the second relation is not a function.

In third relation, at x=6,  the values of y are y=-2 and y=1. For single x, there are more than one value of y, therefore the third relation is not a function.

Please help i need the answer and how you did it
Arturiano [62]
1. First, do 12 x 8 to work out the area of the rectangle, which is 96ft.
Then, to work out the area of a circle, you use the equation πr² to help you. You would multiply π by the radius², which is 16. Now you have just worked out the area of a circle, but not a semicircle, so you would have to divide your answer by two to get the area of this, which would be 25.13 (rounded to 2 d.p).
To get the area of the whole shape, you just have to add the two totals together.
25.13 + 96 = 121.13ft.
Remember to put the units there, or you can lose marks.

Try your best with the next questions! I have written the formulas for the other shapes to help you work out the answers.

Area of a square = Multiply sides together.
Area of rectangle = Multiply width by length.
Area of a circle = Multiply π by the radius².
Area of a semicircle = Multiply π by the radius², and the divide by two.
Area of a triangle = Multiply the base by the height, and then divide by two.

Really hope this helps!

What is the area of this composite figure, in square centimeters?<br> 176<br> 209<br> 242<br> 264
e-lub [12.9K]

Answer:

209

Step-by-step explanation:

We can divide the figure into 2 parts to make this easier.

11x16=176 so the square is 176 square cm.

(11x6)/2 = 66/2 = 33 so the triangle is 33 square cm.

176+33 = 209 sq cm.
