To solve this problem, we need to know the formulas for the areas of each of these shapes. The formula for the area of a circle is πr², the area of a rectangle is b * h, the area for a square is s², and the area for a triangle is 0.5bh. Now we can solve.

1) This is a circle, so the area is πr² = π(6)² = 36<span>π square feet

2) This is a square, so the area is s</span>² = 12² = 144 square yards

3) This is a rectangle, so the area is b * h = 6 * 14 = 84 square inches

4) This is a rectangle, so the area is b * h = 7 * 3 = 21 square inches

5) This is a circle, so the area is πr² = π(4)² = 16<span>π square feet

6) This is a triangle, so the area is 0.5bh = 0.5 (8 * 8) = 0.5 * 64 = 32 yd.</span>²

7) This is a triangle, so the area is 0.5bh = 0.5 (5 * 10) = 50 * 0.5 = 25 yd.²

8) This is a rectangle, so the area is b * h = 10 * 2 = 20 in²

9) This is a square, so the area is s² = 9² = 81 ft²

Please help on this math question!!
katrin2010 [14]

Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= \sqrt{(7\sqrt{(33)^{2} }- (33)^{2}

=\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}

The side that continues next to 33: x -33

Applying similarity property on right triangles:

\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}

(33)(x-33)=(4\sqrt{33} )^{2}

33x-1089=528

33x=528+1089

x=\frac{528+1089}{33} =49

Hope this helps

Camila is putting together gift bags for nurses at a local clinic. Each of the 5 gift bags contains 'x' cookies. Camila adds 3 m
Vladimir [108]

Answer:

A- X= 20÷5-3

B- 20÷5=4; 4-3=1

C- X=1

Step-by-step explanation:

Okay, well we have to work backwards. 20 cookies, and she makes 5 bags. We need to find out what 'x' means. To do that, we take 20 cookies and divide it by 5. 4 cookies. Then we want to take 3 cookies out of each bag to find out how many cookies she first put in. 1 cookie.

Let's check:

bag 1:

o (one cookie)

bag 2:

o (one cookie)

bag 3:

o (one cookie)

bag 4:

o (one cookie)

bag 5:

o (one cookie)

Now we have 15 cookies left. Now let's put 3 in each:

bag 1:

o (one cookie)

v v v ( three cookies)

bag 2:

o (one cookie)

v v v ( three cookies)

bag 3:

o (one cookie)

v v v ( three cookies)

bag 4:

o (one cookie)

v v v ( three cookies)

bag 5:

o (one cookie)

v v v ( three cookies)

Now we have no cookies left, and we put 4 cookies in each. (o representing the first cookie, v representing the next three cookies)

What is the equivalent decimal to this fraction? 10/45 0.2 0.222222222... 0.232323232323... 0.181818181818...​
Ivan

Factorize the numerator and denominator, then simplify:

10/45 = (2×5)/(9×5) = 2/9

Now,

1/9 = 1/10 + 1/90

1/90 = 1/10 × 1/9 = 1/10 × (1/10 + 1/90) = 1/100 + 1/900

1/900 = 1/100 × 1/9 = 1/100 × (1/10 + 1/90) = 1/1000 + 1/9000

and so on, which is to say

1/9 = 1/10 + 1/100 + 1/1000 + …

or

1/9 = 0.111…

so that multiplying both sides by 2 gives

2/9 = 0.222…
