Answer:

A=782\ yd^2

Step-by-step explanation:

The area of the figure is equal to the area of four right triangles

so

The area of one right triangle is equal to

A=\frac{1}{2}(23)(17)

A=195.5\ yd^2

Multiply by 4

A=(4)195.5=782\ yd^2

<em>Alternative Method</em>

The figure is a Rhombus

The area of the Rhombus is equal to

A=\frac{1}{2}(D_1)(D_2)

where

D1 and D2 are the diagonals of the rhombus

we have

D_1=(23+23)=46\ yd\\D_2=(17+17)=34\ yd

substitute

A=\frac{1}{2}(46)(34)

A=782\ yd^2

The square shown has a perimeter of 32 units. The square is rotated about line k. What shape is created by the rotation and what
harkovskaia [24]
The perimeter of the square is calculated through the equation,
                                        4x = P
where P is the perimeter and x is the measure of the sides.

When P is 32 units then,
                                         32 units = 4(x)
                                                 x = 8 inches

This 8 inches is the diameter of the cylinder formed by the rotation. 
The circumference of the base is calculated through,
                            C = 2πr = πD
Substituting the known values,
                              C = π(8 units) = <em>8π units
</em>
<em></em>When π is equal to 3.14, we solve for the numerical value of the cylinder as follows,
<em>                                      C = 8(3.14) = 25.12 units
</em>
<em></em>Thus, the figure formed is a cylinder with base circumference equal to 25 units. The answer is the third choice. <em>

What is 4 minus 1 5/12
klasskru [66]

Answer: 2 and 7/12

Step-by-step explanation: To subtract 4 - 1 and 5/12, first subtract the fractions. Since 4 has no fraction, imagine the fraction 0/12.

Notice however that we can't subtract 0/12 - 5/12.

So, let's rewrite 4 and 0/12 as 3 + 1 and 0/12 or 3 + 12/12 by changing 1 and 0/12 into an improper fraction.

Now we have 3 and 12/12 - 1 and 5/12.

Now we can subtract our fractions 12/12 - 5/12 and we get 7/12. Next we subtract our whole numbers 4 - 1 to get 3.

So 5 - 1 and 5/12 is 2 and 7/12.

26 divided by 5 1/2 I dont know!!
zavuch27 [327]

Answer:

4.727

Step-by-step explanation:

An easy way to think of something being divided by a fraction is by turning the fraction into a decimal. In this case, it's 5 1/2, which is the same as 5.5. So, you can just calculate 26 / 5.5, by hand, or on a calculator, and the answer is 4.727.

<em>Hope this helps!</em>

Subtract the cube root of the product of x and 3y from the square of the sum of a and b.
rosijanka [135]

Answer:

a^2 + b^2 + 2ab - (3xy)^1/3

Step-by-step explanation:

Here we want to make a subtraction

Cube root of the product of x and 3y

x * 3y = 3xy

Cube root of this;

(3xy)^1/3

The sum of a and b is (a + b)

Square of this sum;

(a + b)^2 = a^2 + 2ab + b^2

Now, subtract the cube root

we have;

a^2 + b^2 + 2ab - (3xy)^1/3
