The area of the given composite figure is 74.24cm^2

<h3>Area of composite figure</h3>

The figure is made up of semi circle and rectangle

Area = area of semicircle + Area of rectangle

Area = 3.14(4)^2 + 3(8)

Area = 50.24 + 24

Area. = 74.24cm^2

Hence the area of the given composite figure is 74.24cm^2

A. A newborn red panda weighs 100 grams. A
77julia77 [94]

Answer:

y=100\cdot (1.07)^d

Step-by-step explanation:

Find the expression to represent how much you would expect a cub to weigh d days after it's born as exponential growth function y=a\cdot b^d, where a is the initial panda's weight and b is the rate of growth.​

A newborn red panda weighs 100 grams, then a=100.

A healthy cub gains about 7% of its newborn weight per day, then

b=1+0.07=1.07

Hence,

y=100\cdot (1.07)^d

Alim buys 2 t-shirts for $9.50 each, a 3-pack of socks for $7.95, and a pair of shoes for $7.95 and a pair of shoes for $49.95.
Usimov [2.4K]
First, I add all of my prices together.
$9.50(2)+$7.95+$7.95+$49.95= $84.85
Change 6% to a decimal = .06
Then multiply: 84.85 x .06 =  $5.09
$5.09 is the sales tax
$84.85 + $5.09 = $89.94

Answer: $89.94
I hope this helps :)

30<br> 20<br> Y<br> Find x<br><br> Can someone please help me
irakobra [83]

Answer:

B

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos30° = \frac{\sqrt{3} }{2} , then

cos30° = \frac{adjacent}{hypotenuse} = \frac{x}{20} = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 20\sqrt{3} ( divide both sides by 2 )

x = 10\sqrt{3} → B
