1. Perimeter is 3 + 3 +3 +4 +5 = 18 feet

  Area = 3*3 = 9, 1/2*3*4 = 6, 9 + 6 =15 square feet

2. perimeter = 2.5 +2.5+ 2.5+2.5+0.5+0.5 = 11 meters

   Area = 3*.5 = 1.5, 3*2=6,  6+1.5 = 7.5 square meters

3. perimeter = 3.14*2*3 = 18.84 +8 = 26.8 inches

   Area = 6*4 = 24 + 3.14*3^2 = 28.26 = 28.26 +24 = 52.3 inches

4. surface area = 2*π*6*20+2*π*6^2= 980.2 yards

Volume = π*6^2*20 = 2261.9 cubic yards

5.surface area = 2*(9*7+2*2+2*9) = 190 cm

 Volume = 2*7*9 = 126 cubic cm

6. surface area = <span>2*(11*11+11*11+11*11) = 726 mm</span>

<span>  Volume = 11 *11*11 = 1331 cubic cm</span>

Which ordered pairs in the form (x, y) are solutions to the equation
Ann [662]

Answer:

A, D

Step-by-step explanation:

Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.

If the left side is equal to the right side, it is a solution.

Example:

4x-5y=24

4(-9)-5(-12)=24

-36+60=24

24=24

Remember: if the left side does not equal the right side, it is not a solution.

PLZ HELP!!! CORRECT ANSWER ONLY PLEASE<br><br> What is the value of x?
irina1246 [14]

Answer:

  x = 98 mm

Step-by-step explanation:

The angle bisector YT divides the triangle into proportional segments:

  VY/VT = KY/KT

Filling in the numbers and multiplying by VT, we have ...

  VY/57 = 68/129.2

  VY = 57·68/129.2 = 30

Then we can find x from ...

  x = VY + YK = 30 +68 = 98 . . . mm

The value of x is 98 mm.

Help me please with this I will give brainliest
MAVERICK [17]

Answer:

1. 18

2. 72

3. 90%

Step-by-step explanation:

For number 1

To find percentage you multiply the total number of kids with the percentage.

To do this you have to convert the percent into a decimal by moving the dot 2 times from its original location Ex. 20% = .20 as 20 would look like 20.00 in decimal form.

So .20 x 90 = 18

For number 2

Subtract 18 and 90 to find the remanding kids

For number 3

Divide 72 and 90. Make sure the lower number is being divided.

The answer you will get is .8 so move the decimal back two times because you are converting it to a percentage."

You will then get 80.00 as an answer then from there turn it to a percentage

80%

Hope this helps!
