First multiply five times two, which equals ten. Then, multiply four times zero which equals zero. Finally add four and you get fourteen.

5w - 4w + 4 = 14
5x2 -4x0 +4 =14

First combine the like terms 5w and -4w to get just w.
so now the problem looks like:
 
w + 4= 14

subtract 4 from each side now. and you get the answer:

w = 10

15.What is the area of the segment?
Strike441 [17]

Answer:

The Area of a Segment is the area of a sector minus the triangular piece (shown in light blue here). There is a lengthy reason, but the result is a slight modification of the Sector formula: Area of Segment = θ − sin(θ) 2 × r2 (when θ is in radians) Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)

Ron and Harry both parked their cars at a parking lot. Ron parked his car for 8 hours at $3 per hour and Harry parked his car fo
SpyIntel [72]
Alright, so Ron parked his car for 8 hours at $3 per hour.

Harry parked his car for 7 hours at $3 per hour.

So, per day Ron is spending (8 * 3) = $24 a day
and Harry is spending ( 7 * 3 ) = $21 a day

So now solve for 5 days. 24 * 5 = $120 21 * 5 = $105

Add both together
$120
+
$105

=
Your Answer:
$225 altogether.

<h3>Given:</h3>
  • Trapezium
<h3>To find:</h3>
  • Length of BC
  • Value of "x"
<h3>Solution:</h3>

We can divide the given shape into a triangle and a rectangle.

We'll have to use Pythagoras Theorem.

\large\boxed{Formula:{a}^{2}={b}^{2}+{c}^{2}}

In this question we have to find the hypotenuse so we'll have to add.

Let's substitute the values according to the formula.

BC= {6}^{2}+{7}^{2}

BC= 85

BC =  \sqrt{ 85}

\boxed{BC=9.22 \: cm}

Now, we can find the value of "x"

  • Adjacent= 7 cm
  • Opposite= 6 cm
  • Hypotenuse= 9.22 cm

We can use any one from SOHCAHTOA.

Here I'm using tan.

\large\boxed{Formula: tan(a)= \frac{opp}{adj}}

Let's substitute the values according to the formula.

tan \: x= \frac{6}{7}

We'll have to use tan inverse.

x= {tan}^{-1}(\frac{6}{7})

\boxed{x=40.6°}
