Answer:

Area 5 x 8 = 40cm^2

If 5cm is a perpendicular height then of course its 40cm

But if its slant height then we can do the following by flipping the triangles diagonal to find the longer length that sits perpendicular with the perpendicular line.

47.2cm^2 if using full decimal in diagonal finding

and if rounding diagonal fining to 9.4cm we x by 5 we get 9.4 x 5 = 47cm^2

Step-by-step explanation:

Parallelogram no height

Step 1 we use Pythagoras to get the diagonal measure so we can flip the triangle measure and re calculate .

sqrt of 25+ sqrt 64 = sq rt 89 = 9.43

9.43cm is your hypotenuse diagonal

and then deduct 9.43 - 8 = 1.43cm x 5 use that length and area to deduct from 8x 5 = 40

1/2 x 9.43 x 5 = 23.575

1/2 x 1.43 x 5 = 3.575

23.575 - 3.575 = 20

20+20 = 40cm

If this is shown its proven the slant has been added and taken away.

To represent the method if just slant was given and no height.

In a school of 330 students, 85 of them are in a drama club, 200 of them are in a sports team and 60 of them do both

Neko [114]

Answer:

105/330 = 21/66 = 7/22

7/22 is the answer I think

Step-by-step explanation:

n(U) = 330

n(A) = 85

n(B) = 200

n(A n B) = 60

Now,

n(A U B) = n(A) + n(B) - n(A n B)

or, n(A U B) = 85 + 200 - 60

or, n(A U B) = 285 - 60 = 225

Now,

n(A U B) compliment = n(U) - n(A U B)

n(A U B) compliment = 330 - 225

so, n(A U B) compliment = 105

Now,

probability = 105/330

If f(x)=2x^3-x+c and f(2)=10 then what's the value of c?

Goshia [24]

Answer:

c = -4

Step-by-step explanation:

If f(x) = 2x^3 - x + c and f(2) = 10, plug in 2 for the x values in the function and make the function output 10.

10 = 2(2^3) - 2 + c Now, we only have to deal with one variable, that is c.

10 = 2(8) - 2 + c

10 = 16 - 2 + c

10 = 14 + c

-4 = c After simplifying, we get that c is -4.

To check this, plug in 2 for x, and -4 for c in the function. If the function produces 10 as the result, the halleluja!

f(2) = 2(2^3) - 2 - 4

f(2) = 2(8) - 2 - 4

f(2) = 16 - 2 - 4

f(2) = 10

Evaluate the expression if m = 3.<br><br> 3m^2<br><br><br> (SHOW YOUR WORK)

iragen [17]

The value of given expression when m = 3 is 27

<h3><u>Solution:</u></h3>

Given expression is $3m^2$

We have to evaluate the given expression for m = 3

To find for m is equal to 3, substitute m = 3 in given expression

From given expression,

$\rightarrow 3m^2$

Plug in m = 3 in above expression

$\rightarrow 3(3)^2$ ------ eqn 1

We know that,

$a^2$ can be expanded as,

$a^2=a \times a$

Applying this in eqn 1, we get

$\rightarrow 3(3)^2=3 \times (3 \times 3)$

Simplify the above expression

$\rightarrow 3(3)^2=3 \times (3 \times 3) = 3 \times 9 = 27$

Therefore, for m = 3 we get,

$\rightarrow 3(3)^2=27$

Thus value of given expression when m = 3 is found

Solve the equation in the image

Margaret [11]

Answer: 55

Step-by-step explanation:

$\sqrt[3]{4x-4}=6$

Begin by cubing each side of the equation to get rid of the cubic root.

$(\sqrt[3]{4x-4})^3=(6)^3\\ 4x-4=216$

add 4

$4x-4+4=216+4\\4x=220$

Divide by 4

$\frac{4x}{4}=\frac{220}{4}$

$x=55$
