Answer:

The area is 5 units²

Step-by-step explanation:

∵ The area of the square of side length 3 which contains

the quadrilateral ABCD = 3 × 3 = 9 units²

∵ The area of the 4 triangles on the sides of the quadrilateral ABCD

= 1/2(2)(1) + 1/2(1)(2) + 1/2(2)(1) + 1/2(1)(2) = 4 units²

∴ The area of quadrilateral ABCD = 9 - 4 = 5 units²

Harry measures the big prize wheel on a game show and calculates that it has an area of 12.56 square yards. What is the prize wh

Alex_Xolod [135]

Answer:

The prize wheel diameter is 4.00 yards

Step-by-step explanation:

Area (A) = πd^2/4

πd^2 = 4A

d^2 = 4A/π

d (diameter) = √(4A/π)

A = 12.56 square yards, π = 3.142

d = √(4×12.56/3.142) = √15.99 = 4.00 yards

I really need help

Allushta [10]

Answer:

The Correct Option is C. a =4 , b = 2.

Therefore the values, For a = 4 and b =2 the Quadrilateral PQRS, will be a Parallelogram.

Step-by-step explanation:

Given:

$QR = 4a-1$

$PS = 2a+9$

$PQ = 6b$

$RS = 11b-10$

To Find:

a and b =? for PQRS to be a Parallelogram.

Solution:

For a Parallelogram,

Opposite sides are parallel.
Opposite sides are equal.
Opposite angles are equal.

∴ QR || PS and PQ || SR .....Opposite sides are parallel.

∴ QS = PS and

PQ = SR ..............Opposite sides of Parallelogram are equal.

Substituting the values we get

$QR=PS\\4a+1 = 2a+9\\2a=8\\a=\dfrac{8}{2}=4\\\\\therefore a = 4$

Similarly,

$PQ=RS\\6b = 11b-10\\5b=10\\\\b=\dfrac{10}{5}=2\\\\\therefore b=2$

Therefore the values, For a = 4 and b =2 the Quadrilateral PQRS, will be a Parallelogram.

Since there is a total of 10 balls, then the fraction would be 3/10 , the decimal form would be 0.3, and the word form could be put in many ways. one way would be to say, "out of the total 10 sport balls,3 of them are kickballs."
