<h3>Given :</h3>
  • Base of triangle = 7 yd
  • Height of triangle = 10 yd

\\  \\

<h3>To find:</h3>
  • Area of triangle

\\  \\

We know:-

When base and height of triangle is given we use this formula:

\bigstar \boxed{ \rm Area \: of \: triangle =  \frac{base \times height}{2} }

\\  \\

So:-

\\  \\

\dashrightarrow \sf \: Area \: of \: triangle =  \dfrac{base \times height}{2}  \\

\\  \\

\dashrightarrow \sf \: Area \: of \: triangle =  \dfrac{7 \times 10}{2}  \\

\\  \\

\dashrightarrow \sf \: Area \: of \: triangle =  \dfrac{7 \times 5 \times2 }{2}  \\

\\  \\

\dashrightarrow \sf \: Area \: of \: triangle =  \dfrac{7 \times 5 \times\cancel2 }{\cancel2}  \\

\\  \\

\dashrightarrow \sf \: Area \: of \: triangle =  \dfrac{7 \times 5 \times1 }{1}  \\

\\  \\

\dashrightarrow \sf \: Area \: of \: triangle =7 \times 5

\\  \\

\dashrightarrow \bf \: Area \: of \: triangle =35 {yd}^{2}  \\

\\  \\

\therefore  \underline{\textsf{ \textbf {\: Area \: of \: triangle = \red{35}}} {  \red{\bf{yd} }^{ \red2} }}

\\  \\

Evaluate: ƒ(x) = 3 − 4x and ƒ(-5)
Zolol [24]

Answer:

23

Step-by-step explanation:

f(x)=3 − 4x

Let x=-5

f(-5) = 3-4(-5)

       = 3 -(-20)

      = 3+20

     =23

3 hours = 26.25

---------------------------------
Find wages for 1 hour :
---------------------------------
1 hour = 26.25 ÷ 3 = 8.75

---------------------------------
Find wages for 8 hours :
---------------------------------
8 hours = 8.75 x 8 = $70

---------------------------------
Find wages for a week :
---------------------------------
$70 x 7 = $350

---------------------------------
Salvador
---------------------------------
2 hours = $15

---------------------------------
Find 1 hour :
---------------------------------
1 hour = $15 ÷ 2 = $7.50

---------------------------------
Find 8 hours :
---------------------------------
8 hours = $7.50 x 8 = $60

---------------------------------
Find 1 week :
---------------------------------
1 week = $60 x 5 = $300

---------------------------------
Define x :
---------------------------------
Let x be the number of weeks needed 

---------------------------------
Construct equation :
---------------------------------
350x = 300x + 1000

---------------------------------
Solve for x :
---------------------------------
350x = 300x + 1000

---------------------------------
Take away 300x from both sides :
---------------------------------
50x = 1000

---------------------------------
Divide by 50 :
---------------------------------
x = 20

------------------------------------------------------------------
Answer: It will take 20 weeks.
