Answer:

644ft^2

Step-by-step explanation:

Area of triangle=1/2bh

Area of square=l*l

so we have;

4 triangles with a base of 14ft and height of 16ft and 1 square with l=14ft

AreaTriangle=1/2(14ft)(16ft)=112ft*4=448ft^2

AreaSquare=14ft*14ft=196ft^2

Area Total=448ft+196ft=644ft^2

How fast does a driven gear turn if it has 25 teeth (t) and is driven by a10-tooth driver gear (T) at 250 RPM?

vazorg [7]

Given:

The number of teeth = t = 25

The gear is driven by a 10-tooth driver gear (T) at 250 RPM

Let the speed = s

So, using the ratio and proportion

$\frac{25}{s}=\frac{10}{250}$

Solve for s:

$\begin{gathered} 10s=25\cdot250 \\ \\ s=\frac{25\cdot250}{10}=25\cdot25=625 \end{gathered}$

So, the fear will be driven by 625 RP

Pls help asapp picture attached

Olin [163]

Answer:

Step-by-step explanation:

Angle 1 is 110.

Angle 3 is 2x plus 10.

Angle 1 and 3 are vertically opposite angles.

And vertically opposite angles r equal.

Which means, angle 1=angle 3,and angle 2=angke 4.

Here we only Need angle 2 and 3.

Angke 2= angle 3.

Which is 2x plus 10=110.

Therefore 2x=110-10=100

Therefore x = 100÷2=50

There u have it ma'am.

Determine if the events A and B are independent. Show all steps.

zmey [24]

Answer:

$P(A U B ) = \frac{13}{25}$

Step-by-step explanation:

STEP:-1

Given that events A and B are independent then

P(A ∩B ) = P(A) P(B)

Given that P(A) = 2/5 and P(B) = 1/5

STEP:- 2

P(A ∩B ) = P(A) P(B)

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

$P(A U B ) = P(A) +P(B) - P(A) P(B)$

Step(iii):-

$P(A U B ) = \frac{2}{5} +\frac{1}{5} - \frac{2}{5} X \frac{1}{5}$

$P(A U B ) = \frac{3}{5} - \frac{2}{5} X \frac{1}{5}$

$P(A U B ) = \frac{3}{5} - \frac{2}{25}$

$P(A U B ) = \frac{15-2}{25} = \frac{13}{25}$
