Answer:

745.44 square mm

Step-by-step explanation:

The figure can be decomposed into ...

a semicircle of radius 12.5 mm
a rectangle 12.5 mm by 25 mm
a triangle 12.5 mm by 30 mm

The relevant area formulas are ...

Semicircle: A = 1/2πr² = 1/2π(12.5 mm)² ≈ 245.437 mm²

Rectangle: A = LW = (12.5 mm)(25 mm) = 312.500 mm²

Triangle: A = 1/2bh = 1/2(12.5 mm)(30 mm) = 187.500 mm²

Total area of the figure is ...

245.437 +312.500 +187.500 = 745.437 . . . mm²

The area of the figure is about 745.44 square mm.

Mr. Trager has $500.00 to spend at a bicycle store. All prices listed below include tax. . He buys a new bicycle for $273.98. .

Anon25 [30]

Answer:

2 outfits

Step-by-step explanation:

first you have the total amount of money he has.

next subtract the amount of money he spends on the new bicycle

500-273.98=226.02

next find the total cost of the 3 bicycle reflectors

7.23 times 3 = 21.69

Subtract that total from the remaining amount of money left

226.02 - 21.69 = 204.33

Then subtract the helmet from the remaining money

204.33 - 42.36 = 161.97

now divide the remaining money by 78.12 to find out how many outfits he can buy

161.97 / 78.12 = around 2.07

So the answer is he can only buy 2 outfits with the remaining money

(you can not buy 2.07 outfits)

What is the coefficient of b in the expression b+10? Explain

MariettaO [177]

Hello!

A coefficient is a constant multiplied by a variable. As you can see, b is not being multiplied by a number we can see. The thing is, it still has a coefficient. Isn't 1b the same thing as b? This would mean our coefficient would be 1.

I hope this helps!
