Solution:

Question 3:

The image below gives a vivid explanation of the question

Concept:

The sum of angles in a triangle is

=180^0\begin{gathered} \angle A+\angle B+\angle C=180^0 \\ \angle A=61^0 \\ \angle B=90^0 \\ \angle C=4f+1 \end{gathered}

By substituting the values, we will have

\begin{gathered} \angle A+\angle B+\angle C=180^0 \\ 61^0+90^0+4f+1=180^0 \\ \text{collect similar terms, we will have} \\ 61+90+1+4f=180^0 \\ 152^0+4f=180^0 \\ 4f=180-152^0 \\ 4f=28^0 \\ \text{Divide both sides by 4} \\ \frac{4f}{4}=\frac{28}{4} \\ f=7^0 \end{gathered}

Hence,

The final answer is f = 7°

What is the largest flag jake can draw
alexgriva [62]
The ratio of length to width is 3/2.  Let's set up equations of ratios using first the 25 cm length of the paper and then the 20 cm width:

 3      25 cm
--- = ----------
 2           x

Solving for x, 3x = 50 cm, and x =16 2/3 cm.  This is possible, since 16 2/3 is less than the paper width 20 cm.

 3       20 cm
--- = -----------
 2         x

Solving for x:  3x = 40 cm; x = 40/3 cm, or  x= 13 1/3 cm.  This is possible, but does not make maximum use of the 20 by 30 cm paper.

Answer:  the largest flag Jake can draw on the paper given is 20 cm (length) by 16 2/3 cm.

What is the rate of return when 35 shares of Stock A, purchased for $20/share, are sold for $815? The commission on the sale is
wariber [46]

Cost price:-

\\ \sf\longmapsto 35\times 20

\\ \sf\longmapsto 700

  • Commision=$6
  • Total sold price=815+6=823$

Now

Return=823-700=123

Rate of return

\\ \sf\longmapsto \dfrac{123}{700}\times 100

\\ \sf\longmapsto \dfrac{123}{7}

\\ \sf\longmapsto 17.5\%

h=sqrt(16+36)
h=sqrt(52)
h=sqrt(4*13)
h=sqrt(4) sqrt(13)
h=2 sqrt(13)

Total Area: T.A.=2*(4*6/2)+[4+6+2 sqrt(13)] (8)
T.A.=2*(12)+[10+2 sqrt(13)](8)
T.A.=24+(10)(8)+[2 sqrt(13)](8)
T.A.=24+80+16 sqrt(13)
T.A.=104+16 sqrt(13)

Answer: 
( 104+16 sqrt(13) )
