5 The area of a trapezium is 54 cm^2. The length of one of the parallel sides is 8 cm and the height is 6 cm. Find the length of the other parallel side.​

Answers

Answer 1

Answer:

come here if you want to see

Answer 2

The length of the other parallel side is 10 cm.

Trapezium is a quadrilateral (has four sides and four angles) with a pair of parallel sides. The area (A) of a trapezium is given by:

A = (1/2)(a + b)h

where a and b are the length of the parallel sides, h is the height of the trapezium

Given A = 54, a = 8 cm, h = 6 cm, hence:

54 = (1/2)(8 + b)6

8 + b = 18

b = 10 cm

The length of the other parallel side is 10 cm.

X = 50

Step-by-step explanation:

Both equations TOGETHER equal 180 degrees so you write the equation:

2x + 30 + x = 180

(combine X's. Subtract 30 from both sides):

3x = 150

(divide both sides by 3)

X = 50

The perimeter of a rectangular tennis court is 228 feet. If the length of the court exceeds the twice the width by 6 feet, find its dimensions.

Answers

Answer:

Width= 36 Length=78

Step-by-step explanation:

width= w

length = 2w+6

perimeter = 2(l+w)

228=2(2w+6+w)

228 = 2(3w+6)

228=6w+12

216 =6w

w=36

width= w=36 ft

length = 2w+6 = 2(36)+6=78 feet

Find the measure of Z1 given angle 2 is 70 degrees. ​

Answers

Answer:

Step-by-step explanation:

Since all angles on a straight line add upto 180°,

Angle 1 + Angle 2 = 180

Angle 1 + 70 = 180

Angle 1 = 180 -70

Angle 1 = 110°

there are 500 children in a school for the PT drill they have to stand in such a manner that the number of rows is equal to the number of columns.how many children would be left out in this arangement​

Answers

Answer:

16 children would be left out in this arrangement​

Step-by-step explanation:

Total number of children in a school = 500

For P.T. Drill number of rows = number of columns =x

The number of children who will be left out = 500−x^2  .

The square root of 500 gives remainder as 16 that means, the square of 22 is less than 500 by 16

To make it a perfect square = 500−16=484 Therefore, number of children left will be 16

= 16 children would be left out in this arrangement​

What is arithmetic operations?

A number juggling activity is determined by consolidating operands with one math administrator. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations.

Both the plus sign and the minus sign can be used as operators with prefixes or infixes. Only infix operators can be used to represent all other arithmetic operators.

Given cost of 2/5 pound of grapes is $2

2/5p = 2

where p = pound

p = (2 x 5)/2

1p = 5

1 pound = $5

Therefore the 1 pound of grapes cost $5.

h(-4) = -1

h(-1) = -1

h(0) = 2

Step-by-step explanation:

h(-4) = -1 because -4<-1 and from the instructions if x < -1, it is -1

h(-1) = -1 because -1 = -1

h(0) = 2 because if 1<x<2 than we have to solute this -(x-1)^2 + 3

in this we have to replace x with 0

-(0-1)^2 + 3= -(-1)^2 + 3 = -1 +3 = 2

y is directly proportional to x. When y = 30, x = 6 a) Work out an equation connecting y and x. b) Work out the value of y when x = 12.​

Answers

Answer:
y=5x (your equation)

y=60 (your answer)

Step by step explanation:
You are given two numbers, 6 and 30. Since 6 goes into 30, 5 times, then y(which is equal to 30) is equal to x(which is equal to 6) multiplied by 5, so you get your equation,

Y=5X

then you have to solve for y, so just substitute

Y=5(12)

And simplify

Y=60
