Answer:
198.57 cm^2
Step-by-step explanation:
If we join the 2 semi circles, we get a circle.
We can A = pi*r^2
d= 10, r = 5
Area of circle = pi*5^2 ,
= 25*pi
Since diameter= 10 vertically, it should be 10 horizontally too, but it's divided into 2 because of the 2 semi circles.
Thus, width of each semi circle is 5 cm.
Area of rectangle = l *b
Area = (22-10)*10
Area = 12*10
= 120 cm ^2
Total area = 25pi + 120
= 120 + 25(22/7)
= 120 + 78.57
= 198.57

Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{100}[/tex] ( multiply both sides by 100 )
100 × tan35° = opp , that is
opp ≈ 100 × 0.7002 = 70.02
Thus height of tree = 70.02 + 5 = 75.02 ft
--------------------------------------------------------------------
Using the tangent ratio in the right triangle on the right.
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{25.17}{rope}[/tex] ( multiply both sides by rope )
rope × tan40° = 25.17 ( divide both sides by tan40° )
rope = [tex]\frac{25.17}{tan40}[/tex] = [tex]\frac{25.17}{0.839}[/tex] = 30 ft

Someone invested some money at 8% and $300 more than
twice this amount at 12%. Her total annual income from
the two investments is $548. How much is invested at
each rate?
32
Answers
Answer:
$1600 at 8% and 3500 at 12%
Step-by-step explanation:
The rule of the interest is I = PRT, where
P is the amount of investment R is the rate in decimalT is the timeAssume that the amount of money is $x
∴ P = x
∵ The rate is 8%
∴ R = 8/100 = 0.08
∵ She has an annual income
∴ T = 1
→ Substitute them in the rule to find the interest amount
∴ I = x × 0.08 × 1
∴ I = 0.08x
∵ She invested $300 more than twice the previous amount
∴ P = 2x + 300
∵ The rate is 12%
∴ R = 12/100 = 0.12
∵ T = 1
→ Substitute them in the rule to find the other interest amount
∴ I = (2x + 300) × 0.12 × 1
∴ I = 0.24x + 36
∵ Her total annual income from both investments is $548
→ Add the two amount of interest and equate their sum by 548
∴ 0.08x + 0.24x + 36 = 548
→ Add the like terms in the left side
∴ 0.32x + 36 = 548
→ Subtract 36 from both sides
∴ 0.32x + 36 - 36 = 548 - 36
∴ 0.32x = 512
→ Divide both sides by 0.32
∴ x = 1600
∴ She invested $1600 at 8%
→ Substitute x by 1600 in the expression of the other amount to find it
∵ 2x + 300 = 2(1600) + 300 = 3500
∴ She invested $3500 at 12%

Caelan is saving to buy a vacation home. He inherits some money from a wealthy uncle, then combines this with the $ 24162 he has already saved and doubles the total in a lucky investment. He ends up with $ 146012 , just enough to buy a cabin on the lake. How much did he inherit?
Answers
Answer:
The amount inherited is $48,844
Step-by-step explanation:
Here, we want to know the amount of money inherited by Caelan.
Let the amount be $x
From the question, the amount inherited was combined with 24,162 and doubled in an investment to give 146,012
Thus, the amount before the lucky investment will be;
x + 24,162
Thus , after doubling, the amount becomes;
2(x + 24,162)
and this equals 146,012
2(x + 24,162) = 146,012
divide both sides by 2
x + 24,162 = 73,006
x = 73,006 - 24,162
x = $48,844
